Apremilast for genital erosive lichen planus in women (the AP-GELP Study): study protocol for a randomised placebo-controlled clinical trial. Trials 2021; 22:469. [PMID: 34284808 PMCID: PMC8290211 DOI: 10.1186/s13063-021-05428-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Accepted: 07/06/2021] [Indexed: 11/16/2022] Open
Abstract
Background Genital erosive lichen planus (GELP) is a genital subtype of lichen planus, a chronic autoimmune inflammatory disease of unknown aetiology. In women, GELP is characterised by painful vulvo-vaginal mucosal erosions and scarring, often resulting in poor sexual health and reduced quality of life. Treatment options are limited and often with little effect. Apremilast, a phosphodiesterase 4-inhibitor, has been shown to have a positive effect on psoriasis and other inflammatory skin diseases. We aim to investigate the effect and safety of peroral apremilast in women with GELP in a randomised placebo-controlled double-blinded clinical trial. Methods We will recruit 42 adult women with characteristic clinical and/or histological features of moderate-to-severe GELP from a specialised vulva clinic in Oslo, Norway. The patients will be randomised 1:1 to either apremilast 30 mg BID (with an initial dose titration on days 1–6) or a placebo for 24 weeks. The concomitant use of topical corticosteroids will be allowed. The primary end point will be the mean GELP score, a clinical scoring system, at week 24 in the apremilast-treated patients versus the placebo-treated patients. The secondary end points will include the mean GELP score improvement from weeks 0 to 24, patient-reported use of topical steroids, the pain score on a visual analogue scale and the number of patients with GELP score improvements at weeks 16 and 24. The Physician Global Assessment , Patient Global Assessment and selected quality of life and sexual function assessments will be recorded at weeks 0, 16 and 24. The exploratory endpoints include description of immunohistochemical changes before and after apremilast therapy, assessed in vulvar or vaginal biopsies at weeks 0 and 24. Regular follow-ups for possible adverse events will be conducted. Discussion The study design is based on experience from studies on apremilast in other inflammatory skin diseases using equivalent apremilast doses for approved indications. The trial may provide evidence for the use of apremilast in women with this burdensome genital dermatosis. Trial registration ClinicalTrials.govNCT0365666. Registered on 4 September 2018. Supplementary Information The online version contains supplementary material available at 10.1186/s13063-021-05428-w.

Risk of inflammatory bowel disease in patients with psoriasis, psoriatic arthritis and ankylosing spondylitis initiating interleukin 17 inhibitors: a nationwide population-based study using the French national health data system. Arthritis Rheumatol 2021; 74:244-252. [PMID: 34279061 DOI: 10.1002/art.41923] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Revised: 05/14/2021] [Accepted: 07/08/2021] [Indexed: 11/07/2022]
Abstract
OBJECTIVES To investigate whether IL17-inhibitors (IL17i) initiation in real life is associated with a higher risk of inflammatory bowel disease (IBD) in patients with psoriasis (PsO), psoriatic arthritis and ankylosing spondylitis (PsA/AS). METHODS This nationwide cohort study involved the French national health data system database. All adults with PsO and PsA/AS who were new-users of IL17i during 2016-2019 were included. Two non-exposed PsO and PsA/AS population were included: new-users of (1) apremilast and (2) etanercept. End of follow-up was September 30, 2019. The primary end-point was an occurrence of IBD in a time-to-event analysis with propensity score-weighted Cox and Fine-Gray models. RESULTS A total of 16,793 IL17i new-users (mean age 48.4±13 years; 46% men); 20,556 apremilast new-users (mean age 52.5±14.6 years; 53% men); and 10,245 etanercept new-users (mean age 46.3±15 years; 44% men) were included. Previous systemic treatements were closer between IL17i and etanercept compared with apremilast. IBD occurred in 132 cases: 72 (0.43%) in IL17i new-users, 11 (0.05%) in apremilast new-users and 49 (0.48%) in etanercept new-users. Most IBD cases occurred after 6 months of exposure (82%, 55% and 76% respectively). After propensity score weighting, the risk of IBD was significantly greater with IL17i than apremilast (HRw 3.8, 95%CI 2.1-6.8). No difference was observed between IL17i and etanercept new-users (HRw 0.8, 95%CI 0.5-1.2). CONCLUSION Compared with patients initiating etanercept that displayed the same severity of the underlying disease, IL17i new-users did not present a higher risk of IBD. These results need to be confirmed in other large databases.

Risk of major adverse cardiovascular events in patients initiating biologics/ apremilast for psoriatic arthritis: a nationwide cohort study. Rheumatology (Oxford) 2021; 61:1589-1599. [PMID: 34244706 PMCID: PMC8996783 DOI: 10.1093/rheumatology/keab522] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Revised: 06/20/2021] [Indexed: 11/20/2022] Open
Abstract
Objective Several biological DMARDs (bDMARDs) have demonstrated anti-inflammatory effects in PsA. However, their comparative cardiovascular safety profiles remain unknown. We evaluated the risk of major adverse cardiovascular events (MACEs) in PsA patients on therapy with different classes of bDMARDs and apremilast. Methods This nationwide cohort study involved the administrative healthcare database of the French health insurance scheme linked to the hospital discharge database. All adults with PsA who were new users of bDMARDs/apremilast (neither in the year before the index date) during 2015–19 were included. Patients with previous cardiovascular diseases were excluded. End of follow-up was 31 December 2019. The primary endpoint was an occurrence of MACEs in a time-to-event analysis with propensity score-weighted Cox and Fine–Gray models. Results Between 2015 and 2019, we included 9510 bDMARD new users [mean age 48.5 (s.d. 12.7) years; 42% men], including 7289 starting a TNF inhibitor, 1058 an IL-12/23 inhibitor and 1163 an IL-17 inhibitor, with 1885 apremilast new users [mean age 54.0 (s.d. 12.5) years; 44% men]. MACEs occurred in 51 (0.4%) patients. After propensity score weighting, the risk of MACEs was significantly greater with IL-12/23 (weighted hazard ratio 2.0, 95% CI 1.3, 3.0) and IL-17 (weighted hazard ratio 1.9, 95% CI 1.2, 3.0) inhibitors than TNF inhibitors, with no significant increased risk with apremilast (weighted hazard ratio 1.3, 95% CI 0.8, 2.2). Similar results were observed with the Fine–Gray competing risks survival model. Conclusion Analysis of a large database revealed a small overall number of MACEs, and the risk of MACEs was greater for PsA new users of IL-12/23 and IL-17 vs TNF inhibitors.

Nonclinical genotoxicity and carcinogenicity profile of apremilast, an oral selective inhibitor of PDE4. Regul Toxicol Pharmacol 2021; 125:104985. [PMID: 34237378 DOI: 10.1016/j.yrtph.2021.104985] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 06/16/2021] [Accepted: 06/28/2021] [Indexed: 11/26/2022]
Abstract
Apremilast is an oral, selective small molecule inhibitor of phosphodiesterase-4 (PDE4) that has been approved for the treatment of active psoriatic arthritis, moderate to severe plaque psoriasis, and for patients with oral ulcers associated with Behçet's disease. Apremilast modulates the inflammatory cascade in cells by inhibiting PDE4, thus preventing the degradation of cyclic adenosine monophosphate, resulting in the upregulation of interleukin (IL)-10 and the downregulation of proinflammatory cytokines, including IL-23, interferon gamma (IFNγ), and tumor necrosis factor alpha (TNFα). Here, we evaluated the genotoxic and carcinogenic potential of apremilast using Good Laboratory Practice (GLP)-compliant in vitro and in vivo studies. Apremilast was not genotoxic in the genetic toxicology battery, as evaluated for mutagenicity in the Ames test up to concentrations of 5000 μg/plate, clastogenicity in cultured human peripheral blood lymphocytes up to concentrations of 700 ug/mL was in excess of the solubility limit in culture medium and not able to assess; and negative for the induction of micronuclei in the bone marrow micronucleus test in mice up to doses of 2000 mg/kg/day. Furthermore, apremilast did not increase the incidence of tumors in lifetime rat or mouse carcinogenicity studies up to the maximum tolerated dose. In summary, in non-clinical studies, apremilast is not genotoxic and is not carcinogenic.

Abstract
The present study aimed to develop Apremilast loaded nanostructured lipid carriers (NLCs) for topical delivery to overcome the limitations of oral therapy and increase the efficacy. Apremilast loaded NLCs were prepared by hot emulsification technique. The developed formulation was optimized by Box Behnken design and characterized for size, entrapment efficiency, and zeta potential. The selected formulation was investigated for in-vitro release, ex-vivo skin retention, dermatokinetic, psoriasis efficacy, in-vivo skin retention and skin irritation study. The NLCs characterization results showed its spherical shape with the particle size of 157.91 ± 1.267 nm (0.165 ± 0.017 PDI). The entrapment efficiency and zeta potential were found to be 69.144 ± 0.278% and -16.75 ± 1.40 mV, respectively. The in-vitro release study revealed a controlled release of Apremilast from NLCs up to 24 h. The ex-vivo study showed 3-fold enhanced skin retention compared to conventional gel preparation. The formulation depicted improved psoriasis efficacy indicating reduced TNF-α mRNA expression. The cytotoxicity and skin irritation study revealed the prepared formulation has no toxicity or irritation. The study depicts the NLCs loaded Apremilast can be explored for the topical delivery for treatment of psoriasis with improved skin retention and efficacy.

Long-Term Effectiveness and Drug Survival of Apremilast in Treating Psoriasis: A Real-World Experience. Dermatology 2021; 238:267-275. [PMID: 34091455 DOI: 10.1159/000515763] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Accepted: 03/08/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Apremilast is an oral phosphodiesterase 4 (PDE4) inhibitor used for the treatment of moderate to severe psoriasis. Long-term data on the effectiveness and drug survival of patients treated with apremilast are limited. OBJECTIVE The aim of this study was to analyze the characteristics, effectiveness, and drug survival of patients treated with apremilast in a real-world setting. METHODS We conducted a retrospective cohort study of patients with psoriasis who received at least 1 dose of apremilast between 2015 and 2018. We documented sex; age; type, duration, and severity (using Psoriasis Area Severity Index [PASI] and Dermatology Life Quality Index [DLQI]) of psoriasis; comorbidities; previous treatment modalities; adverse events; and reasons for therapy discontinuation. For drug survival, estimates and efficacy analysis with Kaplan-Meier statistics were used. RESULTS The drug survival rate of the 93 reviewed patients was 69.5% at 6 months, 34.7% at 12 months, and 25.8% at 24 months after initiating therapy. The median survival duration was 8.0 months. Therapy was discontinued in 66.6 and 27.8% due to loss of efficacy and adverse events, respectively. At 24 months, 35.9% had achieved PASI75 response and 23.7% had achieved PASI90 response. Most observed adverse events were gastrointestinal issues, weight loss, and headache. CONCLUSIONS Apremilast is an effective and well-tolerated therapy for patients with moderate to severe psoriasis, especially for patients with difficult-to-treat locations and/or contraindications to other biologics. Furthermore, apremilast was used for patients with a history of nonresponse to biologics and was favored for patients with relatively low PASI (<10) and a high DLQI.

The Protective Effects of Apremilast Against Oxygen-Glucose Deprivation/Reperfusion (OGD/R)-Induced Inflammation and Apoptosis in Astroglia Mediated by CREB/BDNF. Neurotox Res 2021; 39:754-763. [PMID: 33826130 DOI: 10.1007/s12640-021-00340-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 02/03/2021] [Accepted: 02/15/2021] [Indexed: 12/21/2022]
Abstract
Oxygen-glucose deprivation and reoxygenation (OGD/R)-induced impairment of astrocytes may lead to neuronal dysfunction in the central nervous system (CNS). Apremilast is a phosphodiesterase 4 (PDE4) inhibitor primarily used for the treatment of psoriasis and psoriatic arthritis that has demonstrated certain neuroprotective properties. PDE4 is an isoenzyme that degrades 3'-5'-cyclic adenosine monophosphate (cAMP), which serves as a neuroprotective agent by promoting neuronal recovery through protein kinase (PKA)-mediated phosphorylation of cAMP response element-binding protein (CREB) and subsequent expression of the neurotrophic factor brain-derived neurotrophic factor (BDNF) and anti-apoptotic B cell lymphoma (Bcl-2). However, the effects of apremilast in astrocytes have not been elucidated. In the present study, we employed an in vitro model of ischemic stroke using oxygen-glucose deprivation and reoxygenation (OGD/R)-challenged astrocytes to investigate the effects of apremilast against apoptosis (the flow cytometry assay), cell death (the lactate dehydrogenase release assay), oxidative stress (2', 7' dichlorofluorescin diacetate staining), and the expression of the key neuroprotective factors CREB and BDNF (Western blot analysis). Our findings show that treatment with apremilast could significantly reduce astrocyte apoptosis and cell death induced by OGD/R as evidenced by reduced release of glial fibrillary acidic protein (GFAP) and improvement of the Bax/Bcl-2 ratio. The results of MTT assay, measurement of lactate dehydrogenase (LDH) release, and flow cytometry confirmed the improvement in cell viability mediated by apremilast. Importantly, we found that CREB phosphorylation was required for the increases in BDNF and Bcl-2 induced by apremilast as well as the decrease in astrocyte apoptosis. These preliminary findings indicate that apremilast may have the potential to prevent astrocyte cell death and promote neuronal healing in cerebral ischemic injury. Further in vivo research will expand our understanding of these promising results.

Characterization and Outcomes in Patients Treated With Apremilast in Routine Clinical Practice in Spain: Results From the APPRECIATE Study. ACTAS DERMO-SIFILIOGRAFICAS 2021; 112:S0001-7310(21)00202-7. [PMID: 34052202 DOI: 10.1016/j.ad.2021.05.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 04/29/2021] [Accepted: 05/09/2021] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND AND OBJECTIVES It is necessary to expand the knowledge in the use of apremilast in clinical practice. The APPRECIATE study (NCT02740218) aims to describe the characteristics of patients with psoriasis treated with apremilast, to evaluate their perspectives and those of dermatologists, as well as the outcomes obtained in clinical practice in Spain. METHODS Observational, retrospective, cross-sectional, multicenter study of patients with chronic plaque psoriasis who could be contacted 6 (±1) months after apremilast initiation. The data were obtained from medical records and questionnaires from patients and physicians. RESULTS A total of 80 patients were evaluated; at apremilast onset, they showed mean (standard deviation, SD) Psoriasis Area and Severity Index (PASI) = 8.3 (5.3), mean (SD) Dermatology Life Quality Index (DLQI) = 8.9 (6.6). At six months, 58.8% (n=47) of patients continued apremilast treatment (discontinuations due to lack of efficacy [16.3%], safety/tolerability [20.0%]). In patients continuing treatment, PASI75 was achieved by 36.7% of patients; mean (95% CI) DLQI score was 2.2 (0.7-3.6) and mean (SD) Patient Benefit Index score was 2.8 (0.8). Compliance with physicians' expectations was correlated with benefits reported by patients (r=0.636). Adverse events were reported by 56.3% of patients (the most common were diarrhoea and nausea). CONCLUSIONS Patients receiving apremilast for 6 months in Spanish clinical practice, reported substantial improvements in their quality of life (mean DLQI reduced by more than 6 points) and disease severity (PASI75 achieved by over one-third of patients), despite less skin involvement than patients who enrolled in clinical trials.

Abstract
Behçet disease (BD) is a complex, multi-systemic inflammatory condition mainly hallmarked by oral and genital ulcers which can also affect the vessels, gastrointestinal tract, central nervous system and even the axial skeleton. Without a clear classification among autoimmune or autoinflammatory conditions, BD has been recently classified as a MHC-I-opathy. BD aetiology is still obscure, but it is thought that certain microorganisms can elicit an aberrant adaptive immune response in the presence of a permissive genetic background. Altered T-cell homeostasis, mostly Th1/Th17 expansion and Treg impairment, could lead to an overactivation of the innate immunity, which underlies tissue damage and thus, signs and symptoms. Immunosuppression and/or immunomodulation are central to the BD management. A complex armamentarium ranging from classical synthetic disease-modifying antirrheumatic drugs to new-era biologic agents or small molecules is available in BD, with different therapeutic outcomes depending on disease manifestations. However, the precise disease mechanisms that underlie BD symptoms are not fully deciphered, which may limit their therapeutic potential and add a significant layer of complexity to the treatment decision-making process. The aim of the present review is to provide an exhaustive overview of the latest breakthroughs in BD pathogenesis and therapeutic options.

Abstract
INTRODUCTION Data on the characteristics of apremilast patients in real-world settings are limited. We assessed the demographics and disease characteristics of apremilast-treated patients in the Corrona Psoriasis Registry overall and by treatment history. METHODS The Corrona Psoriasis Registry is a large, independent, prospective, observational registry of adult patients (age ≥ 18 years) who initiate an eligible systemic medication for treatment of psoriasis at or after enrollment (incident users) or within 12 months before enrollment (prevalent users). The current analyses included psoriasis patients enrolled in the Corrona Psoriasis Registry between April 1, 2015, and January 7, 2018. Patients were adults (age ≥ 18 years) with psoriasis who were enrolled between April 1, 2015, and January 7, 2018 and initiated apremilast at the time of registry enrollment or a subsequent visit (incident users) or within the 12 months prior to registry enrollment (prevalent users). Patient characteristics were evaluated descriptively at the index date, defined as the enrollment date for prevalent users and the visit when apremilast was initiated for incident users. RESULTS Among 660 patients who initiated apremilast at registry enrollment or a visit thereafter, psoriatic arthritis, hypertension, and hyperlipidemia were common. There were more systemic-experienced (61.4%) versus systemic-naive (38.6%) patients; 43.8% had prior biologic exposure. Most patients were not receiving concomitant systemic treatment (70.2%); 27.4% were receiving concomitant biologic therapy. Most patients had mild or moderate disease (psoriasis-involved body surface area ≤ 10% [76.0%], Investigator Global Assessment ≤ 3 [88.3%], Psoriasis Area and Severity Index ≤ 10 [84.5%]). Dermatologist-reported psoriatic arthritis was present in 47.0% of patients; 33.9% of patients had a Psoriasis Epidemiology Screening Tool score of ≥ 3, suggestive of psoriatic arthritis. Systemic-experienced apremilast patients had higher rates of obesity and comorbidities and experienced a greater impact on quality of life (mean Dermatology Life Quality Index, 7.3 vs. 6.5) versus systemic-naive patients. CONCLUSION In this real-world observational study of apremilast users in the Corrona Psoriasis Registry, most patients had less-severe disease and higher rates of prior exposure to biologic treatments compared with patients with moderate-to-severe psoriasis enrolled in phase 3 clinical studies.

Abstract
Introduction: Psoriasis is an immune-mediated inflammatory skin disorder, which follows a chronic course. Apremilast is a novel phosphodiesterase 4 (PDE4) inhibitor, approved by US-FDA for the treatment of moderate to severe plaque psoriasis and psoriatic arthritis. A majority of the data related to the effectivity and safety of apremilast use in psoriasis is extracted from clinical trials. The present study was planned to get an insight into real-world experience with the use of apremilast in patients with moderate-to-severe plaque psoriasis related to its effectiveness and safety in India. Materials and Methods: The present study was a retrospective one, wherein a review of the medical records of patients with psoriasis was conducted at one center in Kolkata, who were prescribed apremilast for 16 weeks in a community dermatology practice, from December 2017 to May 2018. Results: Out of 39 patients, two patients discontinued treatment due to diarrhea. Only three patients were treatment naïve; the rest had taken some form of systemic therapy before apremilast. At the end of 16 weeks of treatment with apremilast, PASI 100 was achieved in one patient (2.7%), PASI 90 in one (2.7%), PASI 75 in 18 patients (48%), while 14 patients (38%) achieved PASI 50. Eighteen (46%) experienced adverse events, diarrhea being the most common (29.7%). Conclusion: The findings of the present study indicate that apremilast is effective in a real-world setting, as compared with clinical trials in achieving certain endpoints like PASI 75, as was found in other real-world studies in other countries, as well.

Abstract
Background Immune checkpoint inhibitors targeting cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), programmed death-1 receptor (PD-1), and programmed death-1 receptor and its ligand (PD-L1) increased the survival of patients affected by metastatic malignant melanoma. Due to their mechanism of action, these drugs are associated with a unique toxicity profile. Indeed, immune-related adverse events (irAEs) present a wide clinical spectrum representing the Achilles' heel of immunotherapy. Overall, cutaneous toxicities are among the most common irAEs. Immunomodulatory drugs are used for the management of irAEs and can theoretically lead to tumor escape. Case Presentation We report the case of a 75-year-old man with metastatic melanoma receiving the anti-PD1 Pembrolizumab therapy. After 10 treatment cycles, the patient came to our clinic with itchy psoriatic manifestations widespread >30% of the body surface [12.3 Psoriasis Area and Severity Index (PASI) score] that negatively impacted on the patient's quality of life and compliance with immunotherapy. Additionally, he had no positive personal history of psoriasis. Given the severity of the cutaneous manifestations, in a multidisciplinary approach, Apremilast (an oral small molecule PDE4 inhibitor) was started. Furthermore, Pembrolizumab was interrupted for 4 weeks until the improvement of skin lesions and the disappearance of itching. Immunosuppressive methylprednisolone therapy was initiated with a dose of 16 mg/die; then, this initial dose was progressively reduced until discontinuation. After 10 months, the patient had a good general clinical condition with psoriasis complete remission. Moreover, positron emission tomography (PET) and computed tomography (CT) scans showed complete response by immune Response Evaluation Criteria in Solid Tumors (iRECIST). Conclusion To the best of our knowledge, this is the first report on the safety and efficacy of Apremilast for the treatment of immunotherapy-induced psoriasis in metastatic melanoma.

Multidisciplinary Management of the Adverse Effects of Apremilast. ACTAS DERMO-SIFILIOGRAFICAS 2020; 112:134-141. [PMID: 32910923 DOI: 10.1016/j.ad.2020.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 05/31/2020] [Accepted: 08/22/2020] [Indexed: 10/23/2022] Open
Abstract
We present a series of general and specific recommendations based on pathophysiologic considerations for managing the most common adverse effects of apremilast that lead to treatment discontinuation: diarrhea, nausea, and headache. The recommendations are based on a review of the literature and the experience of a multidisciplinary team of 14 experts including dermatologists, rheumatologists, neurologists, gastroenterologists, pharmacists, and nurses. We propose a series of simple algorithms that include clinical actions and suggestions for pharmacologic treatment. The adverse effects of apremilast can be managed from a multidisciplinary approach. The purpose of optimizing management is to bring clinical benefits to patients.

Abstract
PURPOSE OF REVIEW Obesity and psoriasis represent chronic inflammatory states that are interconnected in a vicious cycle, sharing also a degree of synergy. In this review, we aim to decipher the various lines of evidence supporting the bidirectional association between psoriasis and obesity highlighting their pathophysiologic connections as well as we attempt to strategize a therapeutic holistic approach for obese psoriatic patients. RECENT FINDINGS Recent meta-analyses have shown that (1) genetically higher BMI increased the odds of psoriasis occurrence; (2) obesity is associated with higher incidence and prevalence of psoriasis as well as psoriasis severity; (3) obesity is associated with lower efficacy to anti-TNF agents and may predict biologic treatment discontinuation; and (4) weight loss through diet and physical exercise may improve pre-existing psoriasis and prevent from de novo psoriasis. Methotrexate, acitretin, and cyclosporine could worsen hypertension, liver steatosis, and dyslipidemia. Since infliximab and ustekinumab are weight adjusted, they may be ideal drugs to treat obese psoriatic patients. IL-17 inhibitors are very effective independently from body weight; however, they tend to present better clearance rates in normal weight patients. There is a paucity on weight data regarding the efficacious IL-23 inhibitors. Apremilast may induce weight loss as an adverse effect presenting also some beneficial metabolic actions. Finally, simvastatin and some antidiabetic drugs could decrease psoriasis severity. More mechanistic, observational studies and well-conducted RCTs are necessary to decipher the enigmatic link between psoriasis and obesity, and to provide evidence-based specific guidelines for the screening and management of obese psoriatic patients.

Abstract
Apremilast, an oral small molecule, is a phosphodiesterase 4 (PDE-4) blocker. It has been shown to be efficacious in managing psoriasis (PS) and psoriatic arthritis (PSA). In two controlled studies, it was also effective in controlling oral ulcers of Behçet syndrome (Bsy). The main side effects associated with apremilast are diarrhea, nausea and headaches. These are usually transient and apremilast requires almost no laboratory monitoring during its use. An important issue is whether apremilast will also be useful in other debilitating and life-threatening manifestations of Bsy, for which there is yet no negative or positive evidence. The experience with apremilast use in PS/PSA will surely be helpful in foreseeing and managing potential adverse events of apremilast use for any other indication in Bsy. On the other hand, the author does not consider the proposed similarities in disease mechanisms between PS/PSA and Bsy strong enough to guide us as to where and when to use apremilast in Bsy.

Commentary: Phosphodiesterase 4 inhibitors as potential adjunct treatment targeting the cytokine storm in COVID-19. Metabolism 2020; 109:154282. [PMID: 32497535 PMCID: PMC7263254 DOI: 10.1016/j.metabol.2020.154282] [Citation(s) in RCA: 45] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 05/29/2020] [Accepted: 05/30/2020] [Indexed: 01/08/2023]
Abstract
The most severe presentation of COVID-19 is characterized by a hyperinflammatory state attributed to the massive pro-inflammatory cytokine release, called "cytokine storm". Several specific anti-inflammatory/immunosuppressive agents are being evaluated by ongoing clinical trials; however, there is currently insufficient evidence for their efficacy and safety in COVID-19 treatment. Given the role of phosphodiesterase 4 (PDE) 4 and cyclic adenosine monophosphate in the inflammatory response, we hypothesize that selective PDE4 inhibition may attenuate the cytokine storm in COVID-19, through the upstream inhibition of pro-inflammatory molecules, particularly TNF-α, and the regulation of the pro-inflammatory/anti-inflammatory balance. Conversely, other anti-cytokine agents lead to the downstream inhibition of specific targets, such as IL-1, IL-6 or TNF-α, and may not be efficient in blocking the cytokine storm, once it has been triggered. Due to their mechanism of action targeting an early stage of the inflammatory response and ameliorating lung inflammation, we believe that selective PDE4 inhibitors may represent a promising treatment option for the early phase of COVID-19 pneumonia before the cytokine storm and severe multiorgan dysfunction take place. Furthermore, PDE4 inhibitors present several advantages including an excellent safety profile; the oral route of administration; the convenient dosing; and beneficial metabolic properties. Interestingly, obesity and diabetes mellitus type 2 have been reported to be risk factors for the severity of COVID-19. Therefore, randomized clinical trials of PDE4 inhibitors are necessary to explore their potential therapeutic effect as an adjunct to supportive measures and other therapeutic regiments.

Abstract
Nanocrystals can enhance skin penetration of drug by increased saturation solubility, dissolution rate and adhesion on the skin. Apremilast is 'difficult-to-deliver' in viable layers (epidermis, dermis) and stratum corneum (SC) owing to its poor aqueous solubility and modest lipophilicity, respectively. Apremilast is currently available as oral tablet formulation for the indication of psoriasis but its effectiveness is limited by systemic side effects. Therefore, the present study aimed to develop novel nanocrystal-based formulations of apremilast for improved topical delivery. Nanosuspension was prepared using wet media milling and exhibited a mean particle size of 200 nm. The saturation solubility of nanocrystals was improved by 2-fold than micronized apremilast and showed significant advantage during dissolution study. Nanosuspension and micronized apremilast was incorporated into gel and cream and characterized for rheological properties. Skin permeation and ex vivo dermatokinetic study of topical formulations were performed on pig ear skin at a dose of 1% w/w using Franz diffusion cells. Skin permeation studies indicated that non-detectable amount of apremilast permeated through pig ear skin during exposure of formulations. Nanosuspension showed 2.6- and 3.2-fold drug penetration in SC and viable layers, respectively, over microsuspension. Nanogel showed 2.7- and 2.4-fold drug penetration in SC and viable layers, respectively, over microgel. Nanocream showed 1.2- and 2.8-fold drug penetration in SC and viable layers, respectively, over microcream. Thus, nanocrystal-based formulations of apremilast aid in selective delivery into viable layers by crossing the SC barrier. This is of paramount importance in enhancing therapeutic effectiveness utilizing localized delivery and provides an alternative delivery approach for the treatment of psoriasis. Graphical abstract.

Abstract
INTRODUCTION Psoriatic arthritis (PsA) is a chronic immune-mediated inflammatory spondyloarthropathy associated with psoriasis. PsA is frequently associated with metabolic disorders including, obesity, metabolic syndrome, and diabetes mellitus (DM). Type 2 DM is among the most common metabolic disorders, with a prevalence ranging from 2.4 to 14.8% in the general population. METHODS We conducted a narrative review of the English-language studies from January 1989 to September 2019 investigating the risk of type 2 DM in patients with PsA, the pathogenic mechanism linking DM to PsA, and the effects on insulin sensitivity exerted by systemic therapies for PsA. RESULTS The prevalence of type 2 DM in patients with PsA ranges from 6.1 to 20.2%, generally higher when compared to the general population. The higher risk of DM is reported in women with more severe forms of PsA. Elevated serum levels of adipokines, including TNF-α, which inhibits the autophosphorylation of the insulin receptor and suppresses the expression of glucose transporter 4, favor insulin resistance and could partially explain the association between PsA and DM. Moreover, adiponectin and omentin, with insulin-sensitizing and anti-atherogenic properties, are decreased in patients with PsA. Some of the treatments for PsA could affect the glucose homeostasis. Systemic corticosteroids are known to impair insulin resistance, whereas apremilast (phosphodiesterase type 4 inhibitor) and TNF-α inhibitors could exert neutral effect or reduce the insulin-resistance. The role of IL-17 or IL-23 inhibitors has been marginally investigated. CONCLUSIONS Patients affected by PsA have a higher prevalence of type 2 DM compared with the general population. The mechanism linking PsA with DM has not been completely clarified, but some of the principal mediators could be TNF-α and adipokine, especially adiponectin and omentin. Apremilast and TNF-α inhibitor may have a favorable effect and could be safely used in patients with DM.

Abstract
Objective Researchers have confirmed that chronic administration of drugs at high doses causes genotoxicity which serve as first step in development of cancers. Apremilast, a phosphodiesterase-4 inhibitor is Food and Drug Administration (FDA) approved drug for Psoriatic Arthritis. The present study designed to conduct genotoxicity testing using the genotoxic study which give simple, sensitive, economical and fast tools for the assessment of damage of genetic material. Methods To conduct genotoxicity study of Apremilast, 60 Swiss albino male mice divided into 6 groups (n = 10). Group1 served as a normal control group without any treatment, Group 2 treated as a disease control and administered with cyclophosphamide 40 mg/kg, IP. Group 3, 4, 5 and 6 treated as test groups and received 10, 20, 40 and 80 mg/kg/day Apremilast respectively. The total duration of study was 13 weeks. At termination day animals were sacrificed and chromosomal aberration assay (BMCAA) and micronucleus assay (BMMNA) were performed to know the genotoxicity potential of Apremilast. Results The results indicates significant rise in chromosomal aberrations (CA) frequency in bone marrow cells and decrease in the MI of the disease control animals as well as Apremilast treated groups. Further significant (p < 0.001; p < 0.0001) increase in score of micronucleated polychromatic erythrocytes (MNPCEs) and percentage of micronucleated PCEs per 1000 PCEs and decrease in the ratio of polychromatic/normochromatic erythrocytes (PCE/NCE) was observed in micronucleus assay. Genotoxic effect increases with the increase of Apremilast dose. Conclusion: Finding of present indicates that Apremilast shows genotoxic potential on high administration although further detailed toxicity studies required for confirmations.

Treatment Switch Patterns and Healthcare Costs in Biologic-Naive Patients with Psoriatic Arthritis. Adv Ther 2020; 37:2098-2115. [PMID: 32141018 PMCID: PMC7467475 DOI: 10.1007/s12325-020-01262-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Indexed: 01/06/2023]
Abstract
Introduction We compared treatment switch patterns and healthcare costs among biologic-naive patients with psoriatic arthritis (PsA) who initiated apremilast or biologics. Methods A 1:2 propensity score match was used to adjust administrative claims data for adults initiating apremilast or biologics from January 1, 2014, to September 30, 2016, for possible selection bias. Patients had at least 12 months of pre- and post-index continuous enrollment in the Optum Clinformatics™ Data Mart database. Outcomes included switch frequency, days to switch, adherence on index treatment, and healthcare costs (total and per patient per month). Switch rate was defined as the proportion of patients who switched to a new treatment after initiation of the index treatment, and days to switch was calculated as the days between initiation of the index treatment and initiation of the new treatment. Adherence was calculated using the proportion of days covered and the medication possession ratio. The t test and chi-square, Kaplan–Meier, and Wilcoxon rank-sum tests were used to evaluate differences between the cohorts. Results Patient characteristics and switch rates were similar between the matched apremilast (n = 170) and biologic (n = 327) cohorts. After matching, patient characteristics were similar between the matched cohorts. The 12-month switch rates were similar for patients initiating apremilast versus those on biologics (17.7% vs. 25.1%, P = 0.06). This trend was similar at 6 months (7.7% vs. 13.2%, P = 0.07) and 18 months (24.4% vs. 29.3%, P = 0.33). Regardless of treatment switching, 12-month total healthcare costs were lower with apremilast versus biologics (all: $28,423 vs. $41,178, P < 0.0001; switched: $39,803 vs. $51,517, P = 0.0040; did not switch: $25,984 vs. $37,717, P < 0.0001). Conclusions Biologic-naive patients with PsA who initiated apremilast had switch rates similar to biologic users and significantly lower healthcare costs, regardless of treatment switching. Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects an estimated 30% of psoriasis patients who use systemic therapy. Symptoms of PsA, such as joint swelling and tenderness, can be painful and disabling and may worsen quality of life. PsA can also impart a substantial economic burden. Treatment for moderate to severe PsA often involves the use of systemic oral medications (e.g., conventional systemic treatments such as methotrexate or targeted systemic treatments such as apremilast) or biologic therapy given by injection or infusion. Because PsA symptoms and responses to treatment can vary, patients may switch treatments over time. More research is needed to better understand how switching treatments affects healthcare costs among patients starting treatment with apremilast or a biologic for PsA. This study compared treatment switching and healthcare costs among patients with PsA who had never been treated with a biologic and who started treatment with apremilast or a biologic for PsA. Rates of treatment switching at 12 months were similar for patients starting treatment with apremilast versus those starting a biologic. Patients starting treatment with apremilast had significantly lower total healthcare costs compared with those starting a biologic, even if they later switched to a biologic. Healthcare costs calculated per patient per month (PPPM) were also lower with apremilast versus biologics, driven by lower PPPM pharmacy costs. These findings suggest that starting treatment with apremilast may be an effective and cost-effective strategy for managing PsA, even for patients who later switch to a biologic.

Formulation, optimization, and in vitro evaluation of nanostructured lipid carriers for topical delivery of Apremilast. Dermatol Ther 2020; 33:e13370. [PMID: 32250507 DOI: 10.1111/dth.13370] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Revised: 03/12/2020] [Accepted: 03/31/2020] [Indexed: 02/06/2023]
Abstract
This work was aimed to formulate topical Apremilast (APM)-loaded nanostructured lipid carriers (NLCs) for the management of psoriasis. NLCs were prepared by a cold homogenization technique using Compritol 888ATO, oleic acid, Tween 80 and Span 20, and Transcutol P as a solid lipid, liquid lipid, surfactant mixture, and penetration enhancer, respectively. Carbopol 940 was used to convert NLC dispersion into NLC-based hydrogel to improve its viscosity for topical administration. The optimized formulation was characterized for size, polydispersity index (PDI), zeta potential (ZP), percentage of entrapment efficiency (%EE), and surface morphology. Furthermore, viscosity, spreadability, stability, in vitro drug diffusion, ex vivo skin permeation, and skin deposition studies were carried out. APM-loaded NLCs showed a narrow PDI (0.339) with a particle size of 758 nm, a %EE of 85.5%, and a ZP of -33.3 mV. Scanning electron microscopy confirmed spherical shape of NLCs. in vitro drug diffusion and ex vivo skin permeation results showed low drug diffusion, sustained drug release, and 60.1% skin deposition. The present study confirms the potential of the nanostructured lipid form of poorly water-soluble drugs for topical application and increased drug deposition in the skin.

Abstract
Introduction: Apremilast is an oral phosphodiesterase inhibitor, approved for moderate to severe psoriasis in adults. Despite the advancement in dermatology, and the introduction of newer biological drugs, apremilast this is the only novel oral medication that has been introduced to treat psoriasis in the past two decades. Like additional other more traditional oral medications, its advantages and disadvantages should be discussed and compared within this group of oral-systemic medications.Area covered: We conducted a review to assess the safety, efficacy, and adherence of apremilast for psoriasis treatment. The aim of this paper was to provide an overview of apremilast regarding its mechanism of action, indications, and adverse events.Expert opinion: Apremilast has been found to be a safe and efficacious drug for moderate-to-severe psoriasis, and despite minor numerous side effects, most of the patients adhere to the therapy. Therefore, overall, it may be easily embraced as the drug of choice for this category. However, for more severe psoriasis cases newer biological drugs seem to be superior to apremilast.

TGF-β activity restoration and phosphodiesterase 4 inhibition as therapeutic options for inflammatory bowel diseases. Pharmacol Res 2020; 155:104757.

Abstract
In the last decades, the better understanding of inflammatory bowel diseases (IBD) pathogenesis has contributed to the identification of new therapeutic targets that can be modulated to induce and maintain disease remission. Monoclonal antibodies against tumor necrosis factor, interleukin (IL)-12/IL-23p40, and the integrin α4β7 and inhibitors of Janus kinase molecules are valid compounds to limit the function of molecules implicated in the control of IBD-related inflammation. However, not all patients respond to treatment with such drugs, some of them lose response over time and others develop serious side effects, such as infections or malignancies, which lead to the discontinuation of the therapy. Thus, an intensive research is ongoing with the goal to identify new targets and develop novel therapeutic options. In this context, restoration of TGF-β activity and inhibition of phosphodiesterase 4 (PD4) represent two relevant strategies. TGF-β is an immunesuppressive cytokine, whose activity is severely impaired in IBD due to the abundance of the intracellular inhibitor Smad7. Knockdown of Smad7 with a specific antisense oligonucleotide restores TGF-β signalling and dampens effector immune responses in pre-clinical studies and initial clinical trials in Crohn's disease patients, even though a recent phase 3 trial was discontinued due to an apparent inefficacy. PD4 inhibition determines the increase of intracellular levels of cyclic adenosine monophosphate, a mechanism that decreases pro-inflammatory cytokine production. A recent phase 2 study has shown that oral administration of PD4 associates with clinical benefit in patients with ulcerative colitis. In this article, we review the rationale and the available data relative to the use of these two agents in IBD.

The Use of Apremilast in Psoriasis: A Delphi Study. ACTAS DERMO-SIFILIOGRAFICAS 2020; 111:115-134.

Abstract
BACKGROUND Experience in the use of apremilast in clinical practice complements the information available from pivotal clinical trials. MATERIAL AND METHOD Following a review of the literature, a panel of dermatologists with expertise in the management of psoriasis considered 5 scenarios in which the evidence supporting the use of apremilast to treat moderate psoriasis is insufficient or controversial. These scenarios were then assessed using a Delphi questionnaire. RESULTS Consensus was reached on 96 (67%) of the 143 items (positive in 85 and negative in 11). The therapeutic goal for apremilast should be based on 4 outcomes: clinical response, symptoms, quality of life, and patient satisfaction. The scenario in which the use of apremilast was considered to have the greatest possibility of success was in patients with stable moderate psoriasis. Most of the clinicians considered apremilast to be an appropriate treatment when conventional therapies fail or are contraindicated, preferably before the prescription of biologic therapy. Consensus was reached that apremilast is an appropriate treatment for psoriasis in difficult locations, such as the scalp or the palms and soles. It was also agreed that apremilast requires less prescreening and monitoring than other conventional and biologic systemic therapies. CONCLUSIONS Apremilast could be a treatment option for patients with a different profile to that of clinical trial participants. The limitations of this proposal are the absence of consensus on the definition of moderate psoriasis, the lack of real-world evidence on the use of apremilast, and certain aspects related to tolerability.

Abstract
INTRODUCTION In recent years, different studies regarding psoriatic arthritis (PsA) have shown the pathogenetic role of dysfunction of signaling pathways involving the phosphodiesterase-4 enzyme and transcription factors or enzymes belonging to the kinase (JAK)-signal family pathway. These also represent the target of several drugs known as targeted synthetic disease-modifying antirheumatic drugs (tsDMARDs). AREAS COVERED The authors performed a systematic literature search using the PubMed database, as well as through retrieving data from randomized controlled trials, their post-hoc analysis, and pooled data analysis on the efficacy and safety profile of the PDE4 inhibitor (PDE4i), apremilast, and the inhibitors of JAK (JAKis), tofacitinib, filgotinib, baricitinib, and upadacitinib, in PsA. EXPERT OPINION In PsA, the PDE4i, apremilast, and the JAKi, tofacitinib, are effective across multiple clinical domains and have an acceptable tolerability profile, thus expanding the treatment options available for PsA patients. Apremilast and tofacitinib show several advantages mainly represented by their oral administration, a fast onset of action, and a short half-life. Data on tsDMARDs in PsA are still limited, and randomized trials and real-life studies are advocated.

Abstract
Apremilast is an anti-inflammatory agent. It has been a flourishing molecule in the field of dermatology. In the year 2014, Apremilast got its approval for treatment of psoriatic arthritis. Presently it is known to treat a number of other conditions, including atopic dermatitis and plaque psoriasis. Apremilast a phthalimide derivative, is non-hygroscopic in nature. It is practically insoluble in water. Apremilast acts by inhibiting the activity of phosphodiesterase 4 (PDE4), an intracellular enzyme. Analytical method plays a key role to understand the physio-chemical properties of a drug molecule. Because of poor solubility and low permeability, analytical method development and formulation becomes challenging. Till date, there are no standard test methods available to analyze Apremilast. So, a critical review of the analytical techniques of Apremilast was carried out. The literature search was done by screening the papers reporting analytical techniques of Apremilast from year 2014 to 2019. Methodologies particularly UV spectroscopy, HPTLC, HPLC, X-ray diffraction, NMR, LC-MS were collected and reviewed. Interminable efforts are made by the researchers to develop simple, accurate, robust and cost-effective methods of analysis. In pharmaceutical research, this information will aid in the development of new delivery systems. The review will prove beneficial and advantageous pre-formulation studies and will guide the formulation development.

Abstract
Introduction: Apremilast is the new oral drug in the management of moderate-to-severe plaque psoriasis with well-established effectiveness and safety in long-term clinical trials and a few real-world studies. However, its effectiveness and safety in Indian setup have not been reported yet. Materials and Methods: This was retrospective, single-center, longitudinal, observational cohort study where the total study period was 24 weeks. Effectiveness parameters were the proportion of patients achieving psoriasis area and severity index (PASI) 50, 75, 90, and 100 response at week 16 and 24. Safety was measured as the proportion of patients reporting ≥1 adverse event (AE) during the study period. Results: Data of a total of 70 patients were included in our study. At week 16, 76.92%, 41.53%, 15.38%, and 6.15% patients achieved PASI 50, 75, 90, and 100, respectively. At week 24, 81.53%, 58.46%, 29.23%, and 10.76% patients achieved PASI 50, 75, 90, and 100, respectively. Mean percentage reduction in PASI was 67% at week 24 and DLQI score was reduced significantly to 3.4 from mean baseline DLQI score of 10.8 (P < 0.001). 40% of patients reported ≥1 AE during the study period. 5 out of 70 patients discontinued apremilast due to AE. Nausea was most common AE reported by 21.4% patients followed by diarrhea (18.57%), headache (17.4%), vomiting (8%), weight loss (7.69%), myalgia (6.15%), and gastritis (6.15%). Most of the AEs were of mild-to-moderate severity. Conclusion: The results of this study support the long-term use of apremilast monotherapy as an efficacious and safe treatment option for the management of moderate-to-severe plaque psoriasis.

Abstract
Objective: Information on treatment costs for psoriatic arthritis (PsA) can be valuable for payers and providers who make treatment and formulary decisions. This study compared real-world treatment patterns and healthcare costs among biologic-naive patients with PsA initiating apremilast or biologics.Methods: A retrospective cohort study was conducted using the Optum Clinformatics™ claims database. The study included biologic-naive patients with PsA who initiated treatment with apremilast or a biologic between 1 January 2014, and 31 December 2015. Propensity score matching was used to adjust for selection bias. Treatment persistence/adherence and all-cause healthcare costs were evaluated. Cost differences were determined using Wilcoxon rank-sum tests.Results: In all, 125 biologic-naive patients initiating treatment with apremilast were matched to 245 biologic-naive patients initiating treatment with a biologic. Twelve-month treatment persistence was similar for apremilast vs. biologic users (43.2 vs. 36.7%; p = .2277). While persistent on treatment for up to 12 months, total healthcare costs (from all utilizations) were significantly lower among apremilast vs. biologic users ($28,130 vs. $37,093; p < .0001). Likewise, per-patient per-month costs while persistent on treatment were significantly lower among apremilast vs. biologic users whether they switched treatments ($2,455 vs. $3,497; p = .0103), remained persistent on treatment ($2,434 vs. $3,521; p < .0001), or discontinued but did not switch treatments ($2,178 vs. $2,696; p = .0082).Conclusions: Apremilast patients had significantly lower healthcare costs than biologic patients, even when they switched to a biologic, during the 12-month post-index period. These results may be useful to payers and providers seeking to optimize PsA care while reducing healthcare costs.

Complex methodology for rational design of Apremilast-benzoic acid co-crystallization process. Int J Pharm 2019; 570:118639. [PMID: 31465834 DOI: 10.1016/j.ijpharm.2019.118639] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Revised: 08/17/2019] [Accepted: 08/20/2019] [Indexed: 01/09/2023]
Abstract
A new co-crystal of pharmaceutical active ingredient Apremilast was successfully designed in this work. The discovered co-crystal with benzoic acid significantly improves key properties like the dissolution and stability of an otherwise poorly soluble Apremilast. A crystallization process was developed, which includes efficient solvent selection and ternary phase diagram construction to minimize risks during scale up. To increase efficiency, we propose that both steps be combined into a single methodology based on solubility data. A suitable solvent for the co-crystallization process was selected and ternary phase diagrams were constructed using three different modifications of thermodynamic model of solid-liquid equilibria. Based on the obtained information, the co-crystallization process was scaled-up to 100 mL. This provides a feasible process to produce larger amounts of this promising pharmaceutical solid form of Apremilast necessary for further drug development.

Apremilast mechanism of efficacy in systemic-naive patients with moderate plaque psoriasis: Pharmacodynamic results from the UNVEIL study. J Dermatol Sci 2019; 96:126-133. [PMID: 31787506 DOI: 10.1016/j.jdermsci.2019.09.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2019] [Revised: 08/13/2019] [Accepted: 09/06/2019] [Indexed: 01/13/2023]
Abstract
BACKGROUND Pharmacodynamic (PD) subanalyses of clinical trials in patients with moderate to severe psoriasis demonstrated the efficacy of apremilast correlated with reductions in cytokines involved in the pathogenesis of psoriasis. OBJECTIVE This PD subanalysis of a phase IV, randomized, controlled trial (UNVEIL) in systemic-naive patients with moderate plaque psoriasis (psoriasis-involved body surface area [BSA] 5%-10%; static Physician's Global Assessment [sPGA] = 3) evaluated the relationship between efficacy and changes in inflammatory biomarkers with apremilast 30 mg twice daily (BID) versus placebo. METHODS Patients were randomized (2:1) to apremilast 30 mg BID or placebo for 16 weeks. Blood samples were analyzed for interleukins (IL)-17A, -17F, -22, and -23; cardiometabolic biomarkers (leptin; adiponectin; apolipoproteins A-I, A-II, B, and E); and the number of T-helper 17 (Th17) cells, regulatory T cells, and total T cells at Weeks 0, 4, and 16. Correlations were examined between percentage change in biomarkers and efficacy (based on PGAxBSA). RESULTS Of 221 randomized patients, 38 were included in PD analyses (placebo, n = 12; apremilast, n = 26). Median percentage reductions in plasma cytokine levels were significantly greater with apremilast versus placebo for IL-17A (P < 0.05), IL -17F (P < 0.001), and IL-22 (P < 0.01) at Week 4 and IL-22 (P < 0.05) at Week 16. At Week 16, in patients receiving apremilast, improvement in PGAxBSA significantly correlated with change in IL-17A (r = 0.45, P = 0.04). Adipokines, apolipoproteins, and T-cell population levels were largely unchanged. CONCLUSION Clinical improvements in psoriasis correlated with apremilast-mediated decreases in IL-17A without significantly affecting systemic IL-23 levels, adipokines, or Th17 and regulatory T-cell numbers.

Abstract
OBJECTIVE To assess the relative efficacy and safety of apremilast, secukinumab, and ustekinumab at different doses in patients with active psoriatic arthritis (PsA). METHOD A Bayesian network meta-analysis was conducted, which included randomized controlled trials (RCTs) that examined the efficacy and safety of apremilast 20 mg, apremilast 30 mg, secukinumab 75 mg, secukinumab 150 mg, secukinumab 300 mg, ustekinumab 45 mg, and ustekinumab 90 mg compared with placebo. RESULTS Of the RCTs 8 comprising 3289 patients met the inclusion criteria. The American College of Rheumatology (ACR) 20 response rate was significantly higher in the secukinumab 300 mg group than in the placebo group (odds ratio OR, 7.55; 95% confidence interval CI, 3.18-17.63). Secukinumab 150 mg, secukinumab 75 mg, ustekinumab 90 mg, apremilast 30 mg, apremilast 20 mg, and ustekinumab 45 mg were also more efficacious than placebo. There were no significant differences in the efficacy between the interventions. A dose-response relationship among the same drug groups was observed. The number of serious adverse events was not significantly different among the apremilast, secukinumab, ustekinumab, and placebo groups. CONCLUSION All drug treatments were more efficacious than placebo; however, there were no significant differences in the efficacy and safety between the drugs at the different doses.

Abstract
Apremilast is used as a systemic therapy for the treatment of psoriasis and psoriatic arthritis. This drug is considered relatively safe with a very low incidence of serious side effects. Common side effects are diarrhea, nausea, headache, nasopharyngitis, upper respiratory tract infections which are mild to moderate in severity. Diarrhea tends to occur within 2 weeks of starting treatment and resolve spontaneously within 4 weeks without dose adjustment or discontinuation of therapy. Chronic diarrhea and malnutrition due to apremilast have not been reported yet. We report a case of apremilast induced chronic diarrhea leading to malnutrition, necessitating discontinuation of therapy.

Abstract
INTRODUCTION/OBJECTIVE Apremilast, PDE4 competitive inhibitor, has been recently introduced in the treatment of adult psoriatic arthritis (PsA) patients, but only preliminary data are available on imaging evaluation. Thus, we evaluated the response to apremilast in PsA patients by ultrasonographic (US) assessment. METHODS Thirty-four patients (M/F 7/27; median age 61 years, IQR 15; median disease duration 10 years, IQR 13) treated for polyarticular involvement were longitudinally evaluated. All the patients were assessed at baseline (T0), and after 6 (T1), 12 (T2), and 24 weeks (T3) by DAS28, CDAI, SDAI, and DAPSA. At the same time-points, US assessment was performed in 22 sites (wrists, MCPs, PIPs): synovial effusion/hypertrophy and power Doppler were scored with a semi-quantitative scale (0-3). A total score, corresponding to patient's inflammatory status, was obtained by their sum (0-198). We assessed also the presence of tenosynovitis of flexor tendons of hands' fingers bilaterally, registering the number of involved tendons (US-tenosynovitis score 0-10). RESULTS We found a significant reduction in the US inflammatory score values after 6 weeks (T0, median 15 (IQR 11.2); T1, 6 (10.0); P = 0.0002), confirmed at T2 (4.0 (4.0), P = 0.0002) and T3 (4.0 (6.0); P = 0.0003). Finally, US-detected tenosynovitis was observed in 44.1% of patients: a significant improvement in tenosynovitis score was identified at 6 weeks (T0, median 4 (IQR 4); T1, 1 (2); P < 0.0001) and maintained at T2 (0 (IQR 1); P < 0.0001) and T3 ((IQR 1.25); P < 0.0001). CONCLUSIONS Apremilast is able to induce an early and sustained improvement of ultrasonographic inflammatory status at articular and peri-articular level. Key points •Apremilast induces a significant, early, and sustained improvement of inflammatory joint status in psoriatic arthritis patients. •Ultrasonographic assessment is able to monitor articular and peri-articular response to apremilast.

Abstract
Psoriasis is a chronic immune-mediated inflammatory condition, affecting 2–3% of the population. In recent years, advent of biologics, including secukinumab, have been a major advancement in the management of difficult-to-treat plaque psoriasis. However, high cost of biologics is often a deterrent, especially for Indian socioeconomic condition. Apremilast is an oral phosphodiesterase 4 inhibitor that is safe for use along with many other systemic therapies of psoriasis, including biologics. We report two cases of psoriasis on secukinumab therapy for long duration with good response to therapy. Later, addition of apremilast, allowed halving the dose of secukinumab with maintenance of improvement.

Long-term experience with apremilast in patients with psoriatic arthritis: 5-year results from a PALACE 1-3 pooled analysis. Arthritis Res Ther 2019; 21:118. [PMID: 31077258 PMCID: PMC6509758 DOI: 10.1186/s13075-019-1901-3] [Citation(s) in RCA: 47] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Accepted: 04/18/2019] [Indexed: 02/25/2023] Open
Abstract
BACKGROUND The efficacy and safety of apremilast were assessed in patients with psoriatic arthritis (PsA) in three phase III clinical trials with similar designs (PALACE 1, 2, and 3). METHODS Following a 24-week, randomized (1:1:1 to apremilast 30 mg twice daily, 20 mg twice daily, or placebo), double-blind phase and a 28-week blinded active treatment phase, patients could receive apremilast in open-label extension studies for an additional 4 years. Eligible adult patients had active PsA for ≥ 6 months and three or more swollen joints and three or more tender joints despite prior treatment with disease-modifying anti-rheumatic drugs. RESULTS A total of 1493 randomized patients received one or more doses of study medication (placebo: n = 496; apremilast 30 mg twice daily: n = 497; apremilast 20 mg twice daily: n = 500). In patients continuing apremilast treatment, response was sustained without new safety issues. At week 260, 67.2% of remaining patients achieved an ACR20 response, and 44.4% and 27.4% achieved ACR50 and ACR70 responses, respectively. Among patients with baseline enthesitis and dactylitis, 62.4% achieved a Maastricht Ankylosing Spondylitis Enthesitis Score of 0 and 80.9% achieved a dactylitis count of 0, respectively. In patients who had ≥ 3% baseline psoriasis body surface area involvement, 43.6% achieved ≥ 75% reduction from the baseline Psoriasis Area and Severity Index scores. The most commonly reported adverse events (AEs) were diarrhea, nausea, headache, upper respiratory tract infection, and nasopharyngitis, with most diarrhea and nausea AEs occurring within the first 2 weeks of treatment and usually resolving within 4 weeks. Reported rates of depression during the study were low (≤ 1.8%). The majority of patients maintained their weight within 5% of baseline during the study. No new safety concerns or increases in the incidence or severity of AEs were observed over the long term. CONCLUSIONS Apremilast maintained clinical benefit and a favorable safety profile for up to 5 years among patients with PsA.

Abstract
Acrodermatitis continua of Hallopeau (ACH) is a chronic, inflammatory, and relapsing disorder characterized by the progressive destruction of fingernails and toenails. This condition is rare, difficult to treat, and often misdiagnosed. Several antipsoriatic treatments have been used, without any therapeutic guideline and no real improvement. Apremilast is an oral phosphodiesterase 4 inhibitor, approved for the treatment of chronic plaque psoriasis and psoriatic arthritis. It increases the intracellular concentration of cAMP and restores cytokine equilibrium, especially IL-10, which is particularly involved in nail psoriasis. We reported the case of a 58-year-old man affected by ACH, successfully treated with Apremilast, who achieved a complete healing in just 1 month of treatment without any side effect. We suggest this drug as a successful new treatment for ACH, which can improve clinical manifestations rapidly and has no or few adverse effects. Future formal clinical trials and additional case reports are needed to establish the safety and efficacy of Apremilast in the treatment of ACH.

Abstract
Purpose: Apremilast is a phosphodiesterase-4 inhibitor FDA approved for psoriatic arthritis and moderate to severe plaque psoriasis. In recent years, multiple studies have suggested other potential uses for apremilast in dermatology. A summary of these various studies will be a valuable aid to dermatologists considering apremilast for an alternative indication.Materials and methods: The PubMed/MEDLINE and ClinicalTrials.gov databases were queried with the term 'apremilast,' with results manually screened to identify published data on off-label uses of apremilast. The article was structured by the quality of evidence available.Results: Apremilast use in dermatology beyond plaque psoriasis and psoriatic arthritis is frequently described in the literature, with a mixture of positive and negative results. Randomized controlled data is available for Behçet's disease, hidradenitis suppurativa, nail/scalp/palmoplantar psoriasis, alopecia areata, and atopic dermatitis.Conclusion: The relatively safe adverse effect profile of apremilast and its broad immunomodulatory characteristics may make it a promising option in the future for patients with difficult to treat diseases in dermatology, refractory to first line therapies, but further studies will be necessary to clarify its role.

Abstract
Treatment of psoriasis and psoriatic arthritis in patients with concomitant chronic, severe viral infections, particularly HIV or HBV, represents a challenge, due to contraindication to conventional immunomodulating systemic drugs and biologics, including anti-TNF alpha, anti-IL12/23, and anti-IL17 agents. Recently, apremilast, a selective inhibitor of phosphodiesterase E4 has been suggested to be a safe and effective therapeutic option in HIV-infected population with psoriatic arthritis. We report the case of a patient with psoriatic arthritis and concomitant HIV and HBV infection successfully treated with apremilast.

Abstract
Acute lung injury (ALI) due to chemotherapy occurs frequently. It presents a challenge for clinicians managing therapies for different types of cancers. Carfilzomib (Kyprolis™) is a new proteasome inhibitor that shows promise for the treatment of relapsing multiple myeloma. However, several cases of severe ALI have raised concern about the use of carfilzomib against relapsed multiple myelomas. To improve the efficacy of carfilzomib, a new anti-inflammatory drug for psoriasis treatment, apremilast (Otezla™) was investigated for its protective effects against carfilzomib-induced ALI in rats. RT-PCR analyses revealed that carfilzomib administration in rats markedly increased the levels of tumor necrosis factor-alpha and nuclear factor-kappa B and myeloperoxidase activity with a concomitant increase in lipid peroxidation. The anti-inflammatory cytokine, interleukin-10, was downregulated following carfilzomib administration. Reduction in glutathione levels indicated diminished cellular antioxidant defenses in response to carfilzomib-induced ALI. ALI was confirmed by histopathological observations in lung tissue slices. Apremilast administration reduced lung inflammation in terms of reduction in myeloperoxidase activity and levels of tumor necrosis factor-alpha and alveolar infiltrating cells. Apremilast reversed all observed toxic effects of carfilzomib and prevented ALI in rats.

Abstract
Severe atopic dermatitis, which affects both adults and children, is a debilitating disorder with a significant decline of patients' quality of life. Although aetiopathogenic factors are currently a topic of study and interpretation, the main features of atopic eczema are skin barrier disturbance and immune dysregulation. Severe refractory disease that fails to improve with conventional therapy may benefit from biologic therapy. Progress in understanding immunopathology of atopic dermatitis have allowed identification of therapeutic molecular targets in the field of biological therapy. We reviewed the different biological treatments with a focus on novel targeted agents: Systemic immunotherapy (Omalizumab, Dupilumab, Lebrikizumab, Tralokinumab, Nemolizumab, Ustekinumab, Fezakinumab, Tezepelumab, Apremilast, allergen specific immunotherapy), and topical agents (Tofacitinib, Crisaborole).

Abstract
Alopecia areata (AA) is a common autoimmune disease that results in non-scarring hair loss. AA pathogenesis is thought to involve multiple inflammatory cytokines. Apremilast is a phosphodiesterase 4 (PDE4) inhibitor that reduces pro-inflammatory cytokine production. Recent studies demonstrate upregulation of PDE4 in human scalp lesions of AA patients and hair regrowth in a humanized AA mouse model upon apremilast treatment, suggesting a possible potential of apremilast in AA. To assess the efficacy and safety of apremilast in AA, we conducted a double-blind, placebo-controlled single-center pilot study in 30 moderate-to-severe AA patients (≥ 50% scalp involvement) that were randomized 2:1 to receive apremilast (n = 20) or placebo (n = 10) orally for 24 weeks. The primary endpoint was the percentage of patients achieving 50% reduction in severity of alopecia tool (SALT) score (SALT50) at 24 weeks compared to baseline, and the secondary endpoints included the percent change in SALT score at weeks 24 and 48. Eight patients in the apremilast arm withdrew prior to week 24 along with two patients in the placebo group, mostly due to lack of efficacy and adverse events. At 24 weeks, only 1 of 12 apremilast-treated subjects achieved SALT50, and similarly 1 of 8 placebo-treated subjects achieved SALT50. The difference between the mean percent improvement in SALT score at week 24 compared to baseline of the two study arms was not statistically significant (p = 0.38). The lack of treatment response in most of our patients argues against a pathogenic role for PDE4 specifically in moderate-to-severe AA, but targeting this pathway may still be of value in patients with mild AA as there is less of an inflammatory burden in this population. However, future larger studies may be needed to conclude apremilast's lack of efficacy in moderate-to-severe AA.

Abstract
Background: Real-world data differ from clinical trial data. Although some real-world data regarding apremilast use for psoriasis treatment has been reported in Western countries, no such data has been reported in Asian countries. Objective: To study the efficacy, including Psoriasis Area and Severity Index (PASI) and drug survival, and safety of apremilast in Japanese patients with psoriasis. Methods: Data on all the patients treated with apremilast in Kurume University Hospital between May 2017 and June 2018 were retrieved, with June 30 2018, as the data lock date. Efficacy was analyzed by PASI50, PASI75, and PASI90; drug survival by Kaplan-Meier analysis; and drug safety by the proportion of adverse events (AEs). Results: Fourteen of 42 (33.3%) patients achieved PASI75/90; 16 (32%) patients had discontinued apremilast by the data lock date. Drug survival at week 28 was 70%. No serious AEs were reported; the most prevalent one was loose stools/diarrhea (60%), followed by nausea (38%). The most common reason for apremilast discontinuation was primary/secondary failure. Conclusions: Apremilast is safe and effective in Japanese patients with psoriasis. Higher occurrence of loose stools/diarrhea was noted in our cohort than that reported in Western real-world studies on apremilast.

Apremilast Ameliorates Experimental Arthritis via Suppression of Th1 and Th17 Cells and Enhancement of CD4 +Foxp3 + Regulatory T Cells Differentiation. Front Immunol 2018; 9:1662. [PMID: 30072998 PMCID: PMC6058600 DOI: 10.3389/fimmu.2018.01662] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2018] [Accepted: 07/04/2018] [Indexed: 01/08/2023] Open
Abstract
Apremilast is a novel phosphodiesterase 4 (PDE4) inhibitor suppressing immune and inflammatory responses. We assessed the anti-inflammatory effects of Apremilast in type II collagen (CII)-induced arthritis (CIA) mouse model. To determine whether Apremilast can ameliorate arthritis onset in this model, Apremilast was given orally at day 14 after CII immunization. Bone erosion was measured by histological and micro-computed tomographic analysis. Anti-mouse CII antibody levels were measured by enzyme-linked immunosorbent assay, and Th17, Th1 cells, and CD4+Foxp3+ regulatory T (Treg) cells were assessed by flow cytometry in the lymph nodes. Human cartilage and rheumatoid arthritis (RA) synovial fibroblasts (RASFs) implantation in the severe combined immunodeficiency mouse model of RA were used to study the role of Apremilast in the suppression of RASF-mediated cartilage destruction in vivo. Compared with untreated and vehicle control groups, we found that Apremilast therapy delayed arthritis onset and reduced arthritis scores in the CIA model. Total serum IgG, IgG1, IgG2a, and IgG2b were all decreased in the Apremilast treatment groups. Moreover, Apremilast markedly prevented the development of bone erosions in CIA mice by CT analysis. Furthermore, in the Apremilast treated group, the frequency of Th17 cells and Th1 cells was significantly decreased while Treg cells’ frequency was significantly increased. The high dose of Apremilast (25 mg/kg) was superior to low dose (5 mg/kg) in treating CIA. Apremilast treatment reduced the migratory ability of RASFs and their destructive effect on cartilage. Compared with the model group, Apremilast treatment significantly reduced the RASFs invasion cartilage scores in both primary implant and contralateral implant models. Our data suggest that Apremilast is effective in treating autoimmune arthritis and preventing the bone erosion in the CIA model, implicating its therapeutic potential in patients with RA.

Abstract
Providing safe and effective pharmacotherapy to geriatric patients with rheumatologic disorders is challenging. Multidisciplinary care involving rheumatologists, primary care physicians, and other specialties can optimize benefit and reduce adverse outcomes. Oral disease-modifying antirheumatic drugs, including methotrexate, hydroxychloroquine, sulfasalazine, and leflunomide, and the small molecule inhibitors tofacitinib and apremilast have distinctive monitoring requirements and specific adverse reaction profiles. This article provides clinically relevant pearls for use of these interventions in older patients.
