Abstract
Dupilumab (Dupixent®) is a fully human monoclonal antibody against the interleukin (IL)-4 receptor α subunit of IL-4 and IL-4/IL-13 receptor complexes. IL-4 and IL-13 are key cytokines in driving type 2 inflammation, a dominant and largely eosinophilic inflammatory pathway in asthma. Trials evaluating the efficacy of dupilumab in asthma include three pivotal, placebo-controlled, phase 3 or 2b trials of 24-52 weeks' treatment duration in patients aged ≥ 12 years with moderate-to-severe asthma (inadequately controlled with medium-to-high dose inhaled corticosteroids) or severe asthma [dependent on oral corticosteroids (OCS) for control]. In these studies, adding subcutaneous dupilumab (200 or 300 mg every 2 weeks) to background therapy was generally well tolerated and reduced the rate of severe asthma exacerbations, improved lung function, as well as asthma control and, where specified, health-related quality of life (HR-QOL), and enabled OCS maintenance doses to be reduced without impacting asthma control. Dupilumab displayed efficacy across various patient subgroups, although those with heightened type 2 immune activity, including elevated eosinophils and fractional exhaled nitric oxide, tended to have a more prominent treatment benefit. Dupilumab is consequently widely indicated (and a valuable treatment option) as an add-on therapy in patients aged ≥ 12 years who have severe/moderate-to-severe asthma with a type 2 inflammation/eosinophilic phenotype despite conventional treatments or have OCS-dependent asthma.

Abstract
Sotagliflozin (Zynquista™) is the first dual inhibitor of sodium-glucose co-transporter-1 and -2 (SGLT1 and 2). In the phase 3, inTANDEM 1-3 trials, adjunctive use of oral sotagliflozin (200 mg or 400 mg once daily) improved glycaemic control and reduced bodyweight and insulin requirements relative to placebo over 24 weeks of treatment in adults whose type 1 diabetes (T1D) was inadequately controlled by insulin therapy. Similar benefits were seen with the drug in patients who were overweight/obese [i.e. body mass index (BMI) ≥ 27 kg/m2] in inTANDEM 1 and 2 (pooled). The benefits of sotagliflozin were largely maintained over 52 weeks of treatment. Overall, use of sotagliflozin in this setting is generally well tolerated and reduces, or at least does not increase, the likelihood of hypoglycaemia; however, as with other SGLT inhibitors, sotagliflozin carries a risk of diabetic ketoacidosis (DKA). On the basis of its risk/benefit profile, sotagliflozin is indicated in the EU as an adjunct to insulin in adults with T1D with a BMI ≥ 27 kg/m2 who have failed to achieve adequate glycaemic control despite optimal insulin therapy, thus expanding the currently limited adjunctive oral treatment options available for use in this population.

Abstract
Cabozantinib is an inhibitor of multiple receptor tyrosine kinases (RTKs) with roles in cancer pathogenesis. This review focuses on data relevant to the use of cabozantinib tablets (Cabometyx®) in the treatment of hepatocellular carcinoma (HCC) in patients who have been previously treated with the multi-RTK inhibitor sorafenib, an indication for which cabozantinib tablets are approved in the EU and USA. Approval of cabozantinib in this setting was based largely on the findings of CELESTIAL, a phase 3 trial in adults with advanced HCC who had previously received sorafenib, had progressive disease after at least one systemic therapy and had received up to two systemic treatments for their advanced disease. Compared with placebo in this study, cabozantinib prolonged both overall survival and progression-free survival, with these findings largely unaffected by patient/disease characteristics. The tolerability profile of cabozantinib in CELESTIAL was acceptable and consistent with that of other multi-RTK inhibitors, with adverse events that were manageable with dose modification and supportive care. Thus, cabozantinib is a welcome additional treatment option for use in adults with HCC previously treated with sorafenib.

Abstract
Damoctocog alfa pegol (Jivi®) is approved in the USA, EU, Japan and Canada for the treatment and prophylaxis of previously treated patients aged ≥ 12 years with haemophilia A. Formulated with a 60 kDa polyethylene glycol (PEG) moiety, damoctocog alfa pegol is an intravenously (IV) administered recombinant factor VIII (rFVIII) product with a longer terminal half-life than non-PEGylated FVIII and rFVIII products. In the multinational phase II/III PROTECT VIII trial, prophylaxis with damoctocog alfa pegol reduced the likelihood of bleeding in previously treated patients aged ≥ 12 years with severe haemophilia A, with dosing schedules ranging from twice weekly to once every 7 days. Interim data from the ongoing extension phase indicated that the reduced annualized bleeding rates (ABRs) were maintained for up to 5.2 years of prophylaxis with damoctocog alfa pegol. Damoctocog alfa pegol was also effective in treating bleeding episodes and in providing haemostatic control during surgery. Damoctocog alfa pegol was generally well tolerated in adult and adolescent patients with severe haemophilia A, with most adverse events considered to be unrelated to treatment. There were no new or confirmed cases of FVIII inhibitor development and anti-PEG antibodies, observed in some patients, were of low titre and transient. Damoctocog alfa pegol extends the available treatment options in previously treated adults and adolescents with haemophilia A, offering the possibility of up to once-weekly administration for suitable patients.

Abstract
Polatuzumab vedotin (polatuzumab vedotin-piiq; Polivy™) is an antibody-drug conjugate comprising a monoclonal antibody against CD79b (a B cell receptor component) covalently conjugated to the anti-mitotic cytotoxic agent monomethyl auristatin (MMAE) via a cleavable linker. After binding to CD79b on the B-cell surface, polatuzumab vedotin is internalized and the linker is cleaved, releasing MMAE into the cell, where it inhibits division and induces apoptosis. Polatuzumab vedotin is being developed by Genentech (a subsidiary of Roche) for the treatment of haematological malignancies. In June 2019, the US FDA granted accelerated approval to polatuzumab vedotin, in combination with bendamustine plus rituximab, for the treatment of adults with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) who have received at least two prior therapies. Use of the compound in combination with bendamustine plus rituximab is also under regulatory review for relapsed/refractory DLBCL in the EU and is in ongoing phase 1b/2 development in this setting or relapsed/refractory follicular lymphoma (FL) in several countries. Various other polatuzumab vedotin combination therapy regimens are also in phase 1b/2 development for relapsed/refractory non-Hodgkin lymphoma (NHL) [including DLBCL and FL] or in phase 2 or 3 development for previously untreated DLBCL, while polatuzumab vedotin monotherapy has been in phase 1 development for relapsed/refractory B-cell NHL in Japan. This article summarizes the milestones in the development of polatuzumab vedotin leading to this first approval for its use in combination with bendamustine plus rituximab for relapsed/refractory DLBCL.

Abstract
Tapentadol prolonged release (tapentadol PR) [Palexia® SR in EU] is a long-acting tablet formulation of the strong central analgesic tapentadol, which acts as both a μ-opioid receptor (MOR) agonist and a noradrenaline reuptake inhibitor. Tapentadol PR is approved for chronic pain in various countries, with its EU indication (severe chronic pain manageable only with opioid analgesics) being the focus here. Well-designed trials and clinical practice data support tapentadol PR use in this setting. Short term, tapentadol PR was an effective and generally well tolerated analgesic for moderate to severe pain of varying aetiologies, including neuropathic pain. It provided analgesia at least as good as that of conventional strong opioids and appeared more favourable in terms of gastrointestinal tolerability, likely due to less potent MOR binding. Severe back pain with a neuropathic component responded well to moderate-dose tapentadol PR in some patients, while for others, an increase to the maximum recommended tapentadol PR dosage provided analgesia at least as good as that of moderate-dose tapentadol PR plus pregabalin and appeared to have some CNS tolerability benefits. Data also support the use of tapentadol PR in opioid rotation, including when conventional opioids are intolerable. Longer-term data in musculoskeletal pain conditions indicate continued benefit over up to 2 years’ treatment with tapentadol PR with no evidence of tolerance. Thus, tapentadol PR is a useful option for the management of severe chronic pain.

Abstract
Fexinidazole Winthrop (hereafter referred to as fexinidazole) is a DNA synthesis inhibitor developed by the Drugs for Neglected Diseases initiative (DNDi), in collaboration with Sanofi, for the oral treatment of human African trypanosomiasis (HAT) [commonly known as 'sleeping sickness'] and Chagas' disease. The drug is a 5-nitroimidazole derivative first discovered by Hoechst AG (now part of Sanofi) and was identified by the DNDi in 2005 as having activity against Trypanosoma brucei gambiense and T. b. rhodesiense. Under Article 58 of Regulation (EC) no. 726/2004 (a regulatory mechanism for reviewing new medicines destined for use outside of the EU), fexinidazole has been granted a positive opinion by the EMA for the treatment of both the first-stage (haemo-lymphatic) and second-stage (meningo-encephalitic) of HAT due to T. b. gambiense (g-HAT) in adults and children aged ≥ 6 years and weighing ≥ 20 kg. This approval will facilitate and support marketing authorization application in endemic countries in 2019; following registration, fexinidazole will be distributed via the WHO to endemic countries for g-HAT. Phase 3 evaluation of fexinidazole for g-HAT is ongoing in the Democratic Republic of the Congo and Guinea and the drug is also in development for Chagas' disease, with a study currently ongoing in Spain. Clinical development for visceral leishmaniasis is discontinued. This article summarizes the milestones in the development of fexinidazole leading to this first approval for g-HAT.

Abstract
Canagliflozin (Invokana®) is a sodium-glucose co-transporter-2 (SGLT2) inhibitor indicated in various countries worldwide for the once-daily oral treatment of type 2 diabetes (T2D). Canagliflozin lowers blood glucose levels independently of insulin, with the inhibition of SGLT2 reducing renal reabsorption of glucose and increasing excretion of glucose in the urine. In well-designed clinical trials, canagliflozin (as first-line monotherapy or add-on therapy to other antihyperglycaemic agents) improved glycaemic control in adults with T2D, including those of older age and/or at high cardiovascular (CV) risk, and also had beneficial effects on their bodyweight and blood pressure (BP). CV risk reduction, as well as possible renal benefits, were also seen with canagliflozin in T2D patients at high CV risk in the CANVAS Program, an integrated analysis of two large CV outcomes studies. Canagliflozin was generally well tolerated, had a low risk of hypoglycaemia and was most commonly associated with adverse events such as genital and urinary tract infections and increased urination, consistent with its mechanism of action. Although the amputation and fracture risk observed among recipients of the drug require further investigation, canagliflozin is an important option for T2D management in adults.

Abstract
Tofacitinib (Xeljanz®) is the first Janus kinase (JAK) inhibitor approved at a dosage of 5 mg twice daily (BID) in the EU and the USA for the treatment of active psoriatic arthritis (PsA), where it is indicated in combination with methotrexate for patients who have had an inadequate response or who have been intolerant to a prior therapy with a disease-modifying antirheumatic drug (DMARD). Two well-designed phase III trials (OPAL Broaden and OPAL Beyond) in patients with PsA with or without prior tumour necrosis factor inhibitor (TNFi) therapy showed that tofacitinib 5 mg BID (co-administered with methotrexate or another approved conventional synthetic DMARD) significantly improved the key clinical signs/symptoms and disability associated with PsA after 3 months of treatment, while also improving skin psoriasis, enthesitis, dactylitis, physical function and fatigue. According to interim data, the improvements in clinical signs/symptoms were maintained for up to 30 months in the ongoing long-term extension study OPAL Balance, with minimal radiographic progression seen after 12 months' therapy in the OPAL Broaden study. Tofacitinib 5 mg BID had an acceptable tolerability profile, with low incidences of serious infections, malignancies, cardiovascular events and gastrointestinal perforations over 36 months. Changes in laboratory parameters generally remained stable over 36 months of treatment. Although further studies are required to more definitively establish its efficacy and safety, currently available evidence indicates that tofacitinib expands the treatment options available for the treatment of PsA in patients who have had an inadequate response or who have been intolerant to a prior DMARD therapy.

Abstract
A fixed-dose combination of the hepatitis C virus (HCV) NS5B polymerase inhibitor sofosbuvir, the HCV NS5A inhibitor velpatasvir and the HCV NS3/4A protease inhibitor voxilaprevir (sofosbuvir/velpatasvir/voxilaprevir; Vosevi®) is approved in the EU for the treatment of chronic HCV genotype 1, 2, 3, 4, 5 or 6 infection in adults. In the phase III POLARIS trials, in patients who had HCV genotype 1-6 infection with or without compensated cirrhosis, overall rates of sustained virological response at 12 weeks post-treatment (SVR12) with sofosbuvir/velpatasvir/voxilaprevir were high after 8 weeks of treatment in direct-acting antiviral (DAA)-naïve patients and 12 weeks of treatment in DAA-experienced patients. However, 8 weeks of sofosbuvir/velpatasvir/voxilaprevir was inferior to 12 weeks of sofosbuvir/velpatasvir in cirrhotic or non-cirrhotic DAA-naïve patients with HCV genotype 1, 2, 4, 5 or 6 infection and non-cirrhotic DAA-naïve patients with HCV genotype 3 infection, mostly due to an insufficient treatment period. Sofosbuvir/velpatasvir/voxilaprevir was generally well tolerated, with most adverse events being of mild or moderate intensity. The most common adverse events included headache, fatigue, nausea and diarrhoea. In conclusion, sofosbuvir/velpatasvir/voxilaprevir is an important and effective option for the treatment of HCV genotype 1-6 infection in adults, especially those who have previously failed a DAA therapy with or without an HCV NS5A inhibitor.

Abstract
Denosumab (Prolia®; Pralia®) is a human monoclonal antibody targeting the key bone resorption mediator RANKL. The drug is administered via subcutaneous injection once every 6 months and is approved for various indications, including the treatment of postmenopausal (PM) women with osteoporosis at increased/high risk of fracture or failure/intolerance of other osteoporosis therapies (indications featured in this review). Denosumab showed benefit in several phase 3 or 4 studies in PM women with osteoporosis or low bone mineral density (BMD), including the pivotal 3-year double-blind FREEDOM trial and its 7-year open-label extension. Denosumab reduced the risk of vertebral, nonvertebral and hip fractures and increased BMD across skeletal sites versus placebo in FREEDOM, with these benefits maintained over up to 10 years' therapy in the extension. The drug was also more effective in improving BMD than bisphosphonates, including in women switched from a bisphosphonate regimen, in 1-year trials; however, whether these differences translate into differences in anti-fracture efficacy is unclear. Denosumab was generally well tolerated over up to 10 years' treatment, although an increased risk of multiple vertebral fractures was observed after discontinuation of the drug. Thus, denosumab is a key treatment option for PM women with osteoporosis who have an increased/high risk of fracture or failure/intolerance of other osteoporosis therapies, although the potential for multiple vertebral fractures to occur after discontinuation of the drug requires consideration of subsequent management options.

Abstract
GP2015 is the second biosimilar of the reference p75 TNF receptor-Fc fusion protein etanercept. It is approved for use in all indications for which reference etanercept is approved, including rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, non-radiographic axial spondyloarthritis, plaque psoriasis and paediatric plaque psoriasis. GP2015 has similar physiochemical and pharmacodynamic properties to those of reference etanercept, and the pharmacokinetic biosimilarity of the agents has been shown in healthy volunteers. GP2015 demonstrated clinical efficacy equivalent to that of reference etanercept in patients with moderate-to-severe plaque psoriasis; the tolerability, safety and immunogenicity profiles of the two agents were also generally similar. Switching between GP2015 and reference etanercept had no impact on clinical efficacy, tolerability or immunogenicity. The role of reference etanercept in the management of inflammatory autoimmune conditions is well established and GP2015 provides an effective biosimilar alternative for patients requiring etanercept therapy.

Abstract
Cladribine is a deoxyadenosine analogue prodrug that preferentially depletes lymphocytes, key cells underlying multiple sclerosis (MS) pathogenesis. Cladribine tablets (Mavenclad®) represent the first short-course oral disease-modifying drug (DMD) for use in MS. The tablets, administered in two short courses 1 year apart, are indicated for the treatment of adults with highly active relapsing MS on the basis of data from pivotal clinical trials, including the phase 3 study CLARITY and its extension. A cumulative cladribine tablets dose of 3.5 mg/kg administered in this fashion in CLARITY reduced clinical relapse, disability progression and MRI-assessed disease activity and also improved some aspects of health-related quality of life (HR-QOL) versus placebo over 96 weeks in adults with relapsing-remitting MS (RRMS). Moreover, in the 96-week extension (plus 24 weeks' supplemental follow-up), no additional clinical benefit was gained from continuing versus discontinuing cladribine tablets after the first two annual courses of therapy, although MRI activity was more notable in a subset of cladribine tablet recipients who discontinued the drug. In post hoc analyses of CLARITY and/or a phase 2b trial, benefits of cladribine tablets were seen in patients with high disease activity (HDA) relapsing MS that were sometimes greater than in patients without HDA. Cladribine tablets have an acceptable tolerability profile and do not appear to be associated with an increased risk of overall infection or with an increased risk of malignancy (vs. matched reference populations). Active comparisons and longer-term follow-up would be beneficial, although current data indicate that for adults with highly active relapsing MS, cladribine tablets are an effective treatment option with the convenience of low-burden, short-course, oral administration.

Abstract
Lesinurad (Zurampic®) is an oral selective inhibitor of the URAT1 and OAT4 uric acid (UA) transporters of the kidney, via which it inhibits UA reabsorption and thus increases renal UA excretion and lowers serum UA (sUA) levels. Lesinurad 200 mg once daily is indicated for use in combination with a xanthine oxidase inhibitor (XOI) to treat hyperuricaemia in adults with gout who have not achieved target sUA levels with an XOI alone. Approval was based on three 12-month phase 3 trials that evaluated lesinurad in combination with allopurinol in adults with gout inadequately responsive to allopurinol (CLEAR 1 and 2) and in combination with febuxostat in adults with tophaceous gout (CRYSTAL). The target sUA level of <6 mg/dL at 6 months (primary endpoint) was achieved by significantly more lesinurad plus allopurinol than placebo plus allopurinol recipients in the CLEAR trials. In CRYSTAL (which enrolled patients regardless of prior XOI experience, and included 3 weeks of febuxostat before randomization), the proportion of patients who achieved an sUA target of <5 mg/dL did not reach statistical significance between lesinurad plus febuxostat and placebo plus febuxostat at 6 months (primary endpoint), although significantly favoured the lesinurad plus febuxostat group at 12 months. Notably, the sUA target of <5 mg/dL at 6 months was met with lesinurad plus febuxostat in the CRYSTAL subgroup that had uncontrolled hyperuricaemia at baseline, despite having received febuxostat pre-randomization. Lesinurad plus XOI regimens were generally not associated with improvements in flares and tophi in these trials, although clinical benefit became more apparent in 12-month extension studies; the regimens were also generally well tolerated. Thus, lesinurad, in combination with an XOI, is an emerging option for the treatment of hyperuricaemia in adults with gout who have not achieved target sUA levels with an XOI alone.

The biological DMARD (bDMARD) abatacept (Orencia®), a recombinant fusion protein, selectively modulates a co-stimulatory signal necessary for T-cell activation. In the EU, abatacept is approved for use in patients with highly active and progressive rheumatoid arthritis (RA) not previously treated with methotrexate. Abatacept is also approved for the treatment of moderate to severe active RA in patients with an inadequate response to previous therapy with at least one conventional DMARD (cDMARD), including methotrexate or a TNF inhibitor. In phase III trials, beneficial effects on RA signs and symptoms, disease activity, structural damage progression and physical function were seen with intravenous (IV) or subcutaneous (SC) abatacept regimens, including abatacept plus methotrexate in methotrexate-naive patients with early RA and poor prognostic factors, and abatacept plus methotrexate or other cDMARDs in patients with inadequate response to methotrexate or TNF inhibitors. Benefits were generally maintained during longer-term follow-up. Absolute drug-free remission rates following withdrawal of all RA treatments were significantly higher with abatacept plus methotrexate than with methotrexate alone. Both IV and SC abatacept were generally well tolerated, with low rates of immunogenicity. Current evidence therefore suggests that abatacept is a useful treatment option for patients with RA.

Abstract
Ibrutinib (Imbruvica®) is an oral irreversible inhibitor of Bruton's tyrosine kinase, a B-cell receptor (BCR) signalling kinase expressed by various haematopoietic cells, B-cell lymphomas and leukaemias. The drug is indicated for the treatment of certain haematological malignancies, including chronic lymphocytic leukaemia (CLL)/small lymphocytic lymphoma (SLL), which are the focus of this review. In phase III CLL/SLL trials, ibrutinib monotherapy was more effective than chlorambucil in the first-line treatment of elderly patients (RESONATE-2) and more effective than ofatumumab in previously-treated adults (RESONATE). Likewise, a combination of ibrutinib, bendamustine and rituximab was more effective in previously-treated adults than bendamustine plus rituximab in a phase III placebo-controlled study (HELIOS). These ibrutinib regimens were associated with significantly better progression-free survival, overall response rates, and overall survival than the comparators (in protocol-specified or planned analyses), with ibrutinib therapy providing benefit regardless of adverse prognostic factors, such as del(17p)/TP53 mutation and del(11q). Ibrutinib has an acceptable tolerability profile, although certain adverse events (e.g. bleeding and atrial fibrillation) require consideration. Redistribution lymphocytosis can occur, but is not indicative of disease progression. Although longer-term data would be beneficial, ibrutinib is a welcome treatment option for patients with CLL, including those who have higher-risk disease or are less physically fit. Indeed, current EU and US guidelines recommend/prefer the drug for the first- and/or subsequent-line treatment of certain patients, including those with del(17p)/TP53 mutation.

Abstract
Gabapentin enacarbil is an extended-release prodrug of gabapentin that is approved in the USA (Horizant(®)) and Japan (Regnite(®)) for the treatment of moderate to severe primary restless legs syndrome (RLS) in adults [featured indication]. This article summarizes pharmacological, efficacy and tolerability data relevant to the use of oral gabapentin enacarbil in this indication. In double-blind, multicentre trials, treatment with gabapentin enacarbil 600 mg/day for 12 weeks significantly improved the symptoms of moderate to severe primary RLS in adults. Gabapentin enacarbil also significantly improved RLS pain scores and generally improved sleep and mood outcomes. These data are supported by retrospective pooled analyses of three of these trials (XP081, PIVOT RLS I and PIVOT RLS II), with gabapentin enacarbil generally improving symptoms irrespective of disease severity, associated sleep disturbance or prior dopamine agonist use. Responses to gabapentin enacarbil were sustained in longer-term trials, with lower relapse rates in gabapentin enacarbil than placebo recipients in a longer-term maintenance study. Overall, in short and longer-term trials, relatively few patients discontinued treatment, adverse events were mostly mild to moderate in severity, and somnolence/sedation and dizziness were the most commonly reported adverse events. Notably, there were no reports of augmentation or QT-interval prolongation. Gabapentin enacarbil is an important agent for the treatment of adults with moderate to severe primary RLS.

Abstract
Tenofovir alafenamide (tenofovir AF) is a novel oral prodrug of the nucleos(t)ide reverse transcriptase inhibitor (NRTI) tenofovir that has several pharmacological advantages over tenofovir disoproxil fumarate (tenofovir DF), including increased plasma stability and reduced tenofovir systemic exposure. Tenofovir AF has been coformulated with elvitegravir, cobicistat and emtricitabine as a once-daily, single-tablet regimen (elvitegravir/cobicistat/emtricitabine/tenofovir AF; Genvoya(®)) for the treatment of adults and adolescents with HIV-1 infection. With regard to establishing and/or maintaining virological suppression over 48 weeks in randomized, phase III trials, elvitegravir/cobicistat/emtricitabine/tenofovir AF was noninferior to elvitegravir/cobicistat/emtricitabine/tenofovir DF in antiretroviral therapy (ART)-naive adults, and statistically superior (subsequent to established noninferiority) to ongoing treatment with tenofovir DF-containing regimens in ART-experienced adults with virological suppression. In single-arm, phase III trials, elvitegravir/cobicistat/emtricitabine/tenofovir AF also provided high rates of virological suppression among ART-naive adolescents and ART-experienced adults with stable renal impairment. In general, elvitegravir/cobicistat/emtricitabine/tenofovir AF was well tolerated and associated with more favourable renal and bone parameters, but a less favourable lipid profile, than tenofovir DF-containing regimens. Thus, elvitegravir/cobicistat/emtricitabine/tenofovir AF is an alternative single-tablet regimen for adults and adolescents with HIV-1 infection, particularly those with an estimated creatinine clearance of ≥30 to <50 mL/min or an increased risk of tenofovir DF-related bone toxicity.

Abstract
Dapsone 7.5% gel (Aczone®) is indicated for the once-daily topical treatment of acne vulgaris in patients aged ≥12 years. Dapsone is a sulfone antibacterial with anti-inflammatory actions, which are thought to be largely responsible for its efficacy in treating acne vulgaris. In two phase III trials of 12 weeks' duration in patients aged ≥12 years with moderate acne vulgaris, once-daily dapsone 7.5% gel reduced acne severity (as per the Global Acne Assessment Score) and lesion counts versus vehicle. The benefits of dapsone 7.5% gel over vehicle were seen as early as week 2 for inflammatory lesion counts, and from week 4 or 8 for other outcomes. Dapsone 7.5% gel was well tolerated, with a low incidence of treatment-related adverse events, with the majority of adverse events being administration-site related and mild or moderate in severity. Thus, dapsone 7.5% gel is an effective and well tolerated option for the topical treatment of acne vulgaris in patients aged ≥12 years, with the convenience of once-daily application.

Abstract
Certolizumab pegol (Cimzia®) is a subcutaneously administered polyethylene glycolylated (PEGylated) antigen-binding fragment of a recombinant human monoclonal antibody that selectively neutralizes TNFα. The drug is indicated for a variety of inflammatory autoimmune diseases, including Crohn's disease (CD), rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA), based on its benefit in these settings in well-designed clinical trials. In these studies, certolizumab pegol (as first- or subsequent-line therapy) reduced the severity of CD when used as an induction or maintenance therapy, and improved the signs/symptoms and slowed the radiographic progression of RA (with or without concomitant methotrexate), PsA and axSpA. Certolizumab pegol is generally well tolerated, with upper respiratory tract infections, rash and urinary tract infections being among the most frequent adverse reactions. Thus, certolizumab pegol is an effective option for the management of these autoimmune diseases.

Abstract
Mepolizumab (Nucala(®)) is a humanized monoclonal antibody against interleukin-5, a cytokine involved in the development, recruitment and activation of eosinophils (cellular mediators of airway inflammation, hyper-responsiveness and tissue remodelling). The drug is indicated as an add-on treatment for severe eosinophilic asthma, on the basis of its clinical benefit in this setting in the placebo-controlled DREAM, MENSA and SIRIUS trials. Based on the 52-week, phase II, DREAM study (which assessed varying intravenous mepolizumab dosages), intravenous mepolizumab 75 mg every 4 weeks (q4w) and the corresponding (recommended) subcutaneous dosage of 100 mg q4w were studied in the 32- and 24-week phase III MENSA and SIRIUS trials. In patients aged ≥12 years with severe eosinophilic asthma in the phase III studies, adding subcutaneous mepolizumab 100 mg q4w to current asthma therapy significantly reduced the rate of clinically relevant asthma exacerbations and, in those dependent on oral glucocorticoids (OCSs) for asthma control, enabled the daily OCS dose to be significantly reduced, relative to adding placebo. This mepolizumab regimen also significantly improved asthma control, health-related quality of life and (in one of the two studies) lung function, and had acceptable tolerability (with headache the most common adverse event). In the MENSA and SIRIUS extension, COSMOS, mepolizumab provided durable clinical benefit over up to 84 weeks' therapy with no new tolerability concerns. Thus, mepolizumab is a valuable add-on treatment option for adults and adolescents aged ≥12 years who have severe eosinophilic asthma despite optimized standard therapies.

Abstract
Flibanserin (Addyi™) is chemically described as a benzimidazole and is being developed by Sprout Pharmaceuticals for the treatment of hypoactive sexual desire disorder (HSDD). The drug has a high affinity for serotonin 5-HT1A and 5-HT2A receptors (5-HT1A agonist/5-HT2A antagonist) and is believed to treat HSDD by increasing levels of dopamine and noradrenaline and lowering levels of serotonin in the brain. Flibanserin has been approved in the USA for the treatment of premenopausal women with acquired, generalized HSDD. Earlier phase III development of the agent for HSDD in the EU and Canada had been discontinued by Boehringer Ingelheim, following regulatory feedback. Boehringer Ingelheim had also evaluated flibanserin for the treatment of depression but, due to displaying very mild antidepressant activity, its development in this indication was discontinued. This article summarizes the milestones in the development of flibanserin leading to its first approval for HSDD.

Abstract
Patiromer (Veltassa(™)) for oral suspension is a sodium-free potassium binder that is approved in the USA for the treatment of hyperkalaemia. In clinical trials, patiromer significantly reduced serum potassium levels from baseline to week 4 in patients with chronic kidney disease (CKD) and mild to severe hyperkalaemia (OPAL-HK), or CKD, mild to moderate hyperkalaemia and type 2 diabetes mellitus (AMETHYST-DN), who were receiving renin-angiotensin-aldosterone system inhibitors (RAASis; drugs that inhibit the renal excretion of potassium). Among patients in OPAL-HK who had moderate to severe hyperkalaemia at baseline and normokalaemia on patiromer and RAASis at week 4, continuing patiromer for a further 8 weeks maintained reductions in potassium levels more effectively than switching to placebo (i.e. withdrawing patiromer); consequently, fewer patiromer than placebo recipients experienced recurrent hyperkalaemia during this period. Furthermore, almost all patiromer (vs. less than half of placebo) recipients were still receiving RAASi therapy at the end of this trial. In AMETHYST-DN, the significant reduction from baseline in serum potassium levels seen at week 4 was sustained for up to 52 weeks. Patiromer was generally well tolerated in these trials, with no treatment-related serious adverse events or deaths. Commonly occurring treatment-related adverse events include mild to moderate constipation and hypomagnesaemia, and there is a low risk of hypokalaemia. In conclusion, oral patiromer is a useful new option for patients with hyperkalaemia.

Abstract
Asenapine (Saphris(®), Sycrest(®)) is an atypical antipsychotic that is administered sublingually twice daily and is approved for schizophrenia in the USA, Japan and other countries, but not in the EU. This article reviews the pharmacology, clinical efficacy and tolerability profile of asenapine in the treatment of adults with schizophrenia. Clinical trials with asenapine have demonstrated efficacy in terms of both positive and negative symptoms of schizophrenia, although findings have not always been consistent. Across three short-term (6-week) studies in acute schizophrenia (including one in Asian patients), asenapine was generally superior to placebo and had broadly similar efficacy to active controls in improving total scores on the Positive and Negative Syndrome Scale. A meta-analysis of four short-term trials with asenapine (that also included a negative study and a failed trial) also showed significant benefit with asenapine over placebo. In longer-term trials and extensions (up to ≈3 years' duration), asenapine was effective relative to placebo in preventing relapse in schizophrenia, but was less effective than olanzapine in patients with schizophrenia or schizoaffective disorder (according to intent-to-treat LOCF analysis). However, in two trials in patients with persistent negative symptoms of schizophrenia, asenapine and olanzapine were similarly effective in reducing negative symptoms at week 26, with asenapine providing better results than olanzapine at week 52 in one of the extensions. The most frequently reported adverse events with asenapine are somnolence, akathisia and oral hypoesthesia. Although potentially associated with more extrapyramidal symptoms, asenapine appears to have less weight gain and metabolic effects than some other antipsychotic agents, such as olanzapine.

Abstract
Empagliflozin/linagliptin (Glyxambi(®)) is a once-daily sodium glucose co-transporter type 2 (SGLT2) inhibitor and dipeptidyl peptidase (DPP)-4 inhibitor fixed-dose combination product that is approved in the USA as an adjunct to diet and exercise in adults with type 2 diabetes (T2D) when treatment with both empagliflozin and linagliptin is appropriate. This article reviews the clinical efficacy and tolerability of oral empagliflozin/linagliptin in patients with T2D and summarizes the pharmacological properties of the agents. Results of two randomized controlled trials of 52 weeks' duration in adults with T2D demonstrated that empagliflozin/linagliptin improved glycaemic control significantly more than linagliptin when administered as initial therapy (whereas results vs. empagliflozin were mixed in this setting) and significantly more than linagliptin or empagliflozin when administered as an add-on therapy to metformin. In addition to glycaemic control, empagliflozin/linagliptin provided significant weight loss compared with linagliptin in both trials. Empagliflozin/linagliptin was generally well tolerated in patients with T2D, with a low risk of hypoglycaemia and no reports of exacerbations of, or hospitalizations for, heart failure during the trials. As the first SGLT2 inhibitor/DPP-4 inhibitor fixed-dose combination available, empagliflozin/linagliptin is a useful new option for patients with T2D.

Abstract
A fixed-dose tablet comprising ombitasvir (an NS5A replication complex inhibitor), paritaprevir (an NS3/4A protease inhibitor) and ritonavir (a cytochrome P450 inhibitor) taken in combination with dasabuvir (an NS5B polymerase inhibitor) is indicated for the treatment of chronic hepatitis C virus (HCV) genotype 1 infection in several countries, including the USA (copackaged as Viekira Pak(™)) and those of the EU (Viekirax(®) and Exviera(®)). In phase II and III trials, this interferon-free regimen, taken ± ribavirin, provided high rates of sustained virological response 12 weeks post-treatment in adults with chronic HCV genotype 1a or 1b infection, including those with compensated cirrhosis, liver transplants or HIV-1 co-infection. The regimen was generally well tolerated, with nausea, insomnia, asthenia, pruritus, other skin reactions and fatigue being among the most common tolerability issues. Thus, ombitasvir/paritaprevir/ritonavir plus dasabuvir is an effective interferon-free, direct-acting antiviral regimen for use ± ribavirin in a broad range of adults chronically infected with HCV genotype 1.

Abstract
Alirocumab (Praluent(®)) is a monoclonal antibody against proprotein convertase subtilisin/kexin type 9 (PCSK9) that is administered via subcutaneous injection every 2 weeks. Across ten phase III studies from the ODYSSEY clinical trial program in patients with heterozygous familial hypercholesterolemia (heFH) or nonfamilial hypercholesterolemia (nonFH), including some with mixed dyslipidemia, subcutaneous alirocumab 75 or 150 mg every 2 weeks was significantly more effective with regard to reducing low-density lipoprotein-cholesterol (LDL-C) over 24 weeks than comparator agents (i.e. matching placebo, once-daily oral ezetimibe, or modified oral statin therapy), including when administered as monotherapy or in combination with statin therapy, and when administered with non-statin lipid-lowering therapy (LLT) in patients with statin intolerance. Alirocumab provided sustained LDL-C-lowering efficacy over 52-78 weeks' treatment in longer-term trials, and was associated with significantly favorable effects on several other lipid parameters, including non-high-density lipoprotein-cholesterol (non-HDL-C) and lipoprotein (a) [Lp(a)]. Alirocumab was generally well tolerated in phase III trials, with no apparent increase in muscle-related adverse events compared with placebo. Thus, alirocumab is a valuable emerging option for use in patients with hypercholesterolemia, particularly patients with statin intolerance or inadequately-controlled LDL-C despite statin therapy; however, more data are needed to establish its potential cardiovascular benefits.

Abstract
Olodaterol (Striverdi(®) Respimat(®)) is an inhaled long-acting β2-adrenoceptor agonist (LABA) indicated as a once-daily maintenance bronchodilator therapy in adults with COPD. Several well-designed phase III trials have assessed use of the drug over 6 or 48 weeks in this patient population. In these studies, once-daily olodaterol improved lung function relative to placebo over 48 weeks of treatment, with such improvements being achieved and maintained within the 24-h dosage interval, supporting its once-daily administration. In addition, combined analyses of 48-week trials indicated that olodaterol reduces rescue medication use and may also improve dyspnoea and health-related quality of life, and crossover studies showed improvements in exercise endurance after 6 weeks of treatment with the drug. Pooled analyses of crossover studies assessing 24-h bronchodilation after 6 weeks of therapy indicated that once-daily olodaterol has a 24-h bronchodilatory profile generally similar to that of once-daily tiotropium bromide and twice-daily formoterol. Olodaterol was generally well tolerated and had an acceptable cardiovascular and respiratory adverse event profile. However, further longer-term and active comparator-controlled studies would be beneficial, including trials powered to assess COPD exacerbations.
