Impact of prophylactic dexamethasone on the efficacy of immune checkpoint inhibitors plus platinum-based chemotherapy in patients with advanced Non-Squamous Non-Small-Cell lung cancer. Int Immunopharmacol 2023; 125:111138. [PMID: 37948858 DOI: 10.1016/j.intimp.2023.111138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Revised: 10/22/2023] [Accepted: 10/24/2023] [Indexed: 11/12/2023]
Abstract
BACKGROUND Baseline corticosteroids exposure is associated with inferior clinical outcomes in patients with non-small-cell lung cancer (NSCLC) treated with programmed cell death-1 (PD-1) axis blockade. Dexamethasone is a potent corticosteroid used in the prevention of chemotherapy-associated adverse events (CAAEs). OBJECTIVE Since dexamethasone has immunosuppressive properties, this study attempted to elucidate its effects on the efficacy of immunotherapy plus chemotherapy in patients with non-squamous NSCLC. METHODS The study retrospectively analyzed the medical records of 254 advanced non-squamous NSCLC patients who received front-line treatment with a PD-1 pathway inhibitor and platinum-based chemotherapy at three academic institutions. The average dosage of prophylactic dexamethasone per chemotherapy cycle was calculated. Patients were divided into three groups based on the dose of dexamethasone: High-d (≥24 mg), Moderate-d (12-24 mg), and Low-d (<12 mg). Spearman's rank correlation was used to assess the correlation between the dosage of dexamethasone and progression-free survival (PFS). Logistic regression was used to assess the correlation between dexamethasone dosage and the occurrence of immune related adverse effects (irAE). Univariate and multivariate Cox proportional hazards regression models were used to analyze the differences in survival among the different dexamethasone dosage groups. RESULT The dosage of prophylactic dexamethasone was not significantly correlated with PFS (Spearman's rho = -0.103, P = 0.098). Results from the univariate [hazard ratio (HR)Low-d/High-d, 1.00; P = 0.997; HRModerate-d/High-d, 0.85; P = 0.438] and multivariate (HRLow-d/High-d, 0.71; P = 0.174; HRModerate-d/High-d, 0.87; P = 0.512) analyses showed no significant association between dexamethasone and PFS. Dexamethasone did not have significant effect on the objective response rate, disease control rate or overall survival. The toxicity profiles of irAE were similar across all three groups. CONCLUSION The results of this study suggest that the use of prophylactic dexamethasone does not have an adverse effect on the clinical outcomes of non-squamous NSCLC patients treated with PD-1 blockade therapy and chemotherapy. Routine use of dexamethasone for preventing CAAEs should be recommended for patients undergoing combined immunotherapy and chemotherapy.

Abstract
This review examines the role of the neuropeptide substance P within the neuroinflammation that follows traumatic brain injury. It examines it in reference to its preferential receptor, the neurokinin-1 receptor, and explores the evidence for antagonism of this receptor in traumatic brain injury with therapeutic intent. Expression of substance P increases following traumatic brain injury. Subsequent binding to the neurokinin-1 receptor results in neurogenic inflammation, a cause of deleterious secondary effects that include an increased intracranial pressure and poor clinical outcome. In several animal models of TBI, neurokinin-1 receptor antagonism has been shown to reduce brain edema and the resultant rise in intracranial pressure. A brief overview of the history of substance P is presented, alongside an exploration into the chemistry of the neuropeptide with a relevance to its functions within the central nervous system. This review summarizes the scientific and clinical rationale for substance P antagonism as a promising therapy for human TBI.

Abstract
Background Renal fibrosis is the final common pathway of chronic kidney disease (CKD), which is clinically irreversible and without effective therapy. Renal tubules are vulnerable to various insults, and tubular injury is involving in the initiation and evolution of renal inflammation and fibrosis. Neurokinin-1 receptor (NK-1R) functions by interacting with proinflammatory neuropeptide substance P (SP), exerting crucial roles in various neurological and non-neurological diseases. However, its roles in renal inflammation and fibrosis are still unknown. Methods We collected renal biopsy specimens and serum samples of individuals with or without CKD. Additionally, knockout mice lacking NK-1R expression, SP addition and NK-1R pharmacological antagonist treatment in the unilateral ureteral obstruction (UUO) model, and NK-1R-overexpressed HK-2 cells were employed. Results Renal SP/NK-1R and serum SP were increased in patients with CKD and mice experiencing UUO and correlated with renal fibrosis and function. SP addition enhanced UUO-induced progressive inflammatory responses and renal fibrosis, whereas genetically or pharmacologically targeting NK-1R attenuated these effects. Mechanistically, TFAP4 promoted NK-1R transcription by binding to its promoter, which was abolished by mutation of the binding site between TFAP4 and NK-1R promoter. Furthermore, SP acted through the NK-1R to activate the JNK/p38 pathways to modulate cell fate of tubular epithelial cells including growth arrest, apoptosis, and expression of profibrogenic genes. Conclusion Our data reveals that SP/NK-1R signaling promotes renal inflammatory responses and fibrosis, suggesting NK-1R could be a potential therapeutic target for the patients with CKD.

Abstract
The clinical management of glioblastoma (GBM) is still bereft of treatments able to significantly improve the poor prognosis of the disease. Despite the extreme clinical need for novel therapeutic drugs, only a small percentage of patients with GBM benefit from inclusion in a clinical trial. Moreover, often clinical studies do not lead to final interpretable conclusions. From the mistakes and negative results obtained in the last years, we are now able to plan a novel generation of clinical studies for patients with GBM, allowing the testing of multiple anticancer agents at the same time. This assumes critical importance, considering that, thanks to improved knowledge of altered molecular mechanisms related to the disease, we are now able to propose several potential effective compounds in patients with both newly diagnosed and recurrent GBM. Among the novel compounds assessed, the initially great enthusiasm toward trials employing immune checkpoint inhibitors (ICIs) was disappointing due to the negative results that emerged in three randomized phase III trials. However, novel biological insights into the disease suggest that immunotherapy can be a convincing and effective treatment in GBM even if ICIs failed to prolong the survival of these patients. In this regard, the most promising approach consists of engineered immune cells such as chimeric antigen receptor (CAR) T, CAR M, and CAR NK alone or in combination with other treatments. In this review, we discuss several issues related to systemic treatments in GBM patients. First, we assess critical issues toward the planning of clinical trials and the strategies employed to overcome these obstacles. We then move on to the most relevant interventional studies carried out on patients with previously untreated (newly diagnosed) GBM and those with recurrent and pretreated disease. Finally, we investigate novel immunotherapeutic approaches with special emphasis on preclinical and clinical data related to the administration of engineered immune cells in GBM.

Cancer Sci 2020; 112:744-750.

Abstract
Delayed chemotherapy‐induced nausea and vomiting (CINV) is not well controlled in colorectal cancer (CRC) patients undergoing oxaliplatin (L‐OHP)‐based chemotherapy. Whether neurokinin‐1 receptor antagonist addition to a first‐generation 5HT3 antagonist (1st 5‐HT3RA) and dexamethasone (DEX) is beneficial to these patients remains controversial. Furthermore, whether palonosetron (PALO) or aprepitant (APR) is more effective in controlling delayed CINV is unclear. We, therefore, investigated whether PALO+DEX or 1st 5‐HT3RA+DEX+APR was more effective in controlling delayed CINV, and the risk factors for delayed CINV, in CRC patients undergoing L‐OHP–based chemotherapy. Data were pooled from two prospective observational Japanese studies and a phase III trial to compare CINV incidence between the PALO + DEX (PALO) and 5‐HT3RA+DEX+APR (APR) groups by propensity score–matched analysis. CINV risk factors were identified using logistic regression models. The CINV incidence was higher in the PALO group than in the APR group. Logistic regression analysis revealed alcohol consumption, motion sickness, and the PALO+DEX regimen as independent risk factors for delayed nausea, and female sex and the PALO+DEX regimen as those for delayed vomiting. Compared with prophylactic PALO + DEX, 1st 5‐HT3RA+DEX+APR was more effective in controlling delayed CINV. Thus, CRC patients receiving L‐OHP–based chemotherapy should be treated with three antiemetics, including APR.

Abstract
PURPOSE To identify factors associated with chemotherapy-induced vomiting (CIV) control in pediatric patients receiving highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC). MATERIALS AND METHODS An individual, patient-level, pooled analysis was performed using data from five clinical trials of aprepitant or fosaprepitant in pediatric patients receiving HEC or MEC. The proportion of individuals who experienced no vomiting (complete CIV control) during the phase of interest was the primary study end point. The association of acute-phase complete CIV control (from first chemotherapy dose to 24 hours after the last chemotherapy dose of the chemotherapy block) with age, sex, race, cancer type, acute-phase duration, and antiemetic regimen was examined. Association of the same factors and acute-phase complete CIV control with complete CIV control in the delayed phase (end of acute phase until ≤ 96 hours later) was examined. RESULTS A total of 735 patients (mean age, 8.9 years; range, 0.3 to 17.9 years) were included in the acute-phase analysis. Acute-phase complete CIV control was less likely in older patients (relative risk [RR], 0.97 per year; 95% CI, 0.96 to 0.98 per year) and longer acute-phase duration (RR, 0.89 per day; 95% CI, 0.84 to 0.94 per day). Receipt of ondansetron plus aprepitant or fosaprepitant was associated with a higher likelihood of acute-phase complete CIV control versus ondansetron alone (RR, 1.28; 95% CI, 1.09 to 1.50). Delayed-phase complete CIV control was more likely in patients with acute-phase complete CIV control (RR, 1.19; 95% CI, 1.06 to 1.34) and in those who received aprepitant or fosaprepitant. CONCLUSION Younger age, shorter acute-phase duration, and antiemetic regimen were associated with acute-phase complete CIV control in pediatric patients receiving HEC or MEC. Acute-phase complete CIV control and antiemetic regimen were associated with delayed-phase complete CIV control.

Abstract
Pharmacological interventions of diabetic gastroparesis (DG) constitute an essential element of a patient’s management. This article aimed to systematically review the available pharmacological approaches of DG, including their efficacy and safety. A total of 24 randomised clinical trials (RCTs) that investigated the efficacy and/or safety of medications targeting DG symptoms were identified using several online databases. Their results revealed that metoclopramide was the only approved drug for accelerating gastric emptying and improving disease symptoms. However, this medication may have several adverse effects on the cardiovascular and nervous systems, which might be resolved with a new intranasal preparation. Acceptable alternatives are oral domperidone for patients without cardiovascular risk factors or intravenous erythromycin for hospitalised patients. Preliminary data indicated that relamorelin and prucalopride are novel candidates that have proven to be effective and safe. Future RCTs should be conducted based on unified guidelines using universal diagnostic modalities to reveal reliable and comprehensive outcomes.

Abstract
BACKGROUND Olanzapine, neurokinin-1-receptor-antagonists (NK-1-RA), and thalidomide added to palonosetron + dexamethasone (PALO-DEX) have been evaluated in separate studies as prophylaxis for chemotherapy-induced nausea and vomiting (CINV) due to highly emetogenic chemotherapy (HEC). We conducted a Bayesian network meta-analysis to compare the prophylactic efficacy of these agents in combination with PALO-DEX. METHODS PubMed, Medline/Ovid, Embase, and Clinicaltrials.gov were searched from inception through 22 Mar 2018. Study quality was assessed using the Cochrane methodology. A Bayesian network meta-analysis using random-effects models was used to asses complete response (CR) and rate of no nausea (RNN) in acute, delayed, and overall phases and were expressed as odds ratios (OR) and 95% credible interval (95% CrI). Ranking probabilities of treatments were calculated using the surface under the cumulative ranking curve (SUCRA) to identify the probability of a given treatment as the best option against the worst option. RESULTS Nine RCTs involving two thousand nine hundred fifty-nine patients were included. The olanzapine-based regimen showed greater CR in the acute, delayed, and overall-phases versus the PALO-DEX regimen (OR = 3.97, 95% CrI = 1.02-19.13; OR = 5.62, 95% CrI = 1.66-28.58; OR = 4.79, 95% CrI = 1.40-24.02, respectively). Additionally, it showed greater RNN than the NK-1-RA-based and the PALO-DEX regimens in the delayed phase only (OR = 2.90, 95% CrI = 1.34-5.15; OR = 4.53, 95% CrI = 1.89-10.55, respectively). Olanzapine-, NK-1-RA-, and thalidomide-based regimens did not differ in CR in the three phases. SUCRA probabilities ranked the olanzapine-based regimen as the best option in terms of CR and RNN, while ranking the NK-1-RA-based regimens as the second best option in terms of CR throughout the three phases. CONCLUSION Based on the data included in the analyses, there is insufficient evidence to support adding thalidomide or NK-1-RA to PALO-DEX in preventing CINV induced by HEC. However, adding olanzapine to PALO-DEX achieves better CR and RNN. Olanzapine side-effects and the absence of direct comparisons explain why some guidelines are cautious in suggesting the use of olanzapine.

Abstract
Introduction: The addition of neurokinin-1 receptor antagonists (NK1RAs) to standard prophylaxis of 5-hydroxytryptamine-3 RA (5-HT3RA) plus dexamethasone more effectively prevents chemotherapy-induced nausea and vomiting (CINV) associated with highly and moderately emetogenic chemotherapy. Areas covered: This review presents the evidence base for the use of oral and intravenous (IV) NK1RAs, focusing on the pharmacologic and clinical properties as a class, and highlighting differences between agents. A PubMed literature search was conducted from 2000 to 2018. Expert opinion: Adherence to international antiemetic guidelines remains a clinical challenge. Strategies to simplify antiemetic regimens and facilitate their administration may improve compliance and treatment outcomes. The use of fixed-combination antiemetics offers clinical utility, in combining an NK1RA with a 5-HT3RA in a single oral dose. The use of long-lasting NK1RAs and administering CINV prophylaxis closer to the time of chemotherapy may also assist with guideline and treatment compliance, diminishing the need for home-based administration, and potentially reducing resource utilization. The availability of IV and oral formulations of NK1RAs and NK1RA-5-HT3RA fixed combinations offers further utility, particularly for those patients unsuited for oral administration. However, safety considerations with respect to injection site toxicity and hypersensitivity reactions of the new NK1RA IV formulations deserve close attention.

Comparison of palonosetron and granisetron in triplet antiemetic therapy in nonmetastatic breast cancer patients receiving high emetogenic chemotherapy: a multicenter, prospective, and observational study. Cancer Chemother Pharmacol 2019; 83:1091-1097. [PMID: 30963213 DOI: 10.1007/s00280-019-03831-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2018] [Accepted: 04/03/2019] [Indexed: 10/27/2022]
Abstract
PURPOSE We aimed to investigate the efficacy of 0.25 mg dose of palonosetron and granisetron in triplet antiemetic prophylaxis in breast cancer patients receiving HEC. METHODS Patients with nonmetastatic breast cancer who received HEC [doxorubicin or epirubicin plus cyclophosphamide (AC/EC)] were enrolled in the study. The prophylactic triplet antiemetic regimens were used according to the doctor's preference during the first cycle of HEC as intravenous dexamethasone and palonosetron 0.25 mg or granisetron 3 mg on day 1 as well as oral aprepitant (125 mg on day 1 and 80 mg on days 2 and 3).The primary endpoint was complete response rate (CR) on acute and delayed chemotherapy-induced nausea and vomiting (CINV), separately. RESULTS A total of 118 female patients were included in the study. Patients received AC (83%), EC (3%), and dose-dense AC (14%) as adjuvant (88%) or neoadjuvant (12%). The majority of patients received palonosetron (59%) containing antiemetic treatment. The CR rate on acute and delayed vomiting was very high and not statistically different in both of the arms (acute 87% vs. 96%, p = 0.089; delayed 90% vs. 92%, p = 0.489), respectively. Nevertheless, the CR rate on either acute or delayed nausea was lower than vomiting (acute 51% vs. 51%; delayed 38% vs. 29%, p = 0.203; respectively). CONCLUSIONS This is the second study that compared a 0.25 mg dose of palonosetron with first-generation setron in triplet antiemetic prophylaxis in cancer patients receiving HEC. We could not find meaningful statistical differences between two arms, regarding CR rate on acute and delayed CINV.

Abstract
Background Co-administration of multiple antiemetics that inhibit several molecular pathways involved in emesis is required to optimize chemotherapy-induced nausea and vomiting (CINV) control in patients receiving highly emetogenic chemotherapy (HEC). NEPA, a fixed combination of a highly selective NK1 receptor antagonist, netupitant (300 mg), and the pharmacologically distinct 5-HT3RA, palonosetron (PALO 0.50 mg), has shown superior CINV prevention compared with PALO in cisplatin and anthracycline/cyclophosphamide-based settings. This study is the first head-to-head comparison of NEPA versus an aprepitant (APR)/granisetron (GRAN) regimen. Patients and methods This randomized, double-blind phase III study conducted in Asia was designed with the primary objective to demonstrate non-inferiority of a single oral dose of NEPA compared with a 3-day oral APR/GRAN regimen in chemotherapy-naïve patients receiving cisplatin-based HEC. All patients also received oral dexamethasone (DEX) on days 1–4. The primary efficacy endpoint was complete response (CR: no emesis/no rescue medication) during the overall (0–120 h) phase. Non-inferiority was defined as a lower 95% CI greater than the non-inferiority margin set at − 10%. Secondary efficacy endpoints included no emesis, no rescue medication, and no significant nausea (NSN). Results Treatment groups were comparable for the 828 patients analyzed: predominantly male (71%); mean age 54.5 years; ECOG 0–1 (98%); lung cancer (58%). NEPA demonstrated non-inferiority to APR/GRAN for overall CR [NEPA 73.8% versus APR/GRAN 72.4%, 95% CI (−4.5%, 7.5%)]. No emesis [NEPA 75.0% versus APR/GRAN 74.0%, 95% CI (−4.8%, 6.9%)] and NSN rates [NEPA 75.7% versus APR/GRAN 70.4%, 95% CI (−0.6%, 11.4%)] were similar between groups, but significantly more NEPA patients did not take rescue medication [NEPA 96.6% versus APR/GRAN 93.5%, 95% CI (0.2%, 6.1%)]. NEPA was well tolerated with a similar safety profile to APR/GRAN. Conclusions In this first study comparing NK1RA regimens and DEX, NEPA administered only on day 1 was non-inferior to a 3-day oral APR/GRAN regimen in preventing CINV associated with HEC.

Abstract
Chemotherapy-induced nausea and vomiting (CINV) can be prevented in most patients receiving appropriate antiemetic treatment. However, inadequate uptake of current antiemetic guideline recommendations by physicians, and poor treatment adherence by patients, lead to suboptimal CINV control. There is an unmet need to optimize guideline-consistent use of antiemetics to improve CINV management and prevention. Herein, we provide an overview of CINV, then discuss oral and intravenous NEPA, the first fixed combination antiemetic, composed of netupitant/fosnetupitant and palonosetron. We describe the main pharmacologic and pharmacokinetic characteristics of NEPA, and review the clinical evidence supporting its use in the prevention of CINV.

Abstract
The neurokinins are indisputably essential neurotransmitters in numerous pathoand physiological events. Being widely distributed in the Central Nervous System (CNS) and peripheral tissues, their discovery rapidly promoted them to drugs targets. As a necessity for molecular tools to understand the biological role of this class, endogenous peptides and their receptors prompted the scientific community to design ligands displaying either agonist and antagonist activity at the three main neurokinin receptors, called NK1, NK2 and NK3. Several strategies were implemented for this purpose. With a preference to small non-peptidic ligands, many research groups invested efforts in synthesizing and evaluating a wide range of scaffolds, but only the NK1 antagonist Aprepitant (EMENDT) and its prodrug Fosaprepitant (IVEMENDT) have been approved by the Food Drug Administration (FDA) for the treatment of Chemotherapy-Induced and Post-Operative Nausea and Vomiting (CINV and PONV, respectively). While non-peptidic drugs showed limitations, especially in side effect control, peptidic and pseudopeptidic compounds progressively regained attention. Various strategies were implemented to modulate affinity, selectivity and activity of the newly designed ligands. Replacement of canonical amino acids, incorporation of conformational constraints, and fusion with non-peptidic moieties gave rise to families of ligands displaying individual or dual NK1, NK2 and NK3 antagonism, that ultimately were combined with non-neurokinin ligands (such as opioids) to target enhanced biological impact.

Abstract
AIM We compare neurokinin-1 receptor antagonist (NK-1RA)-based triple regimen and conventional duplex regimen for antiemetic efficacy for patients with moderately emetogenic chemotherapy (MEC). Patients & methods: Pooled risk ratios (RRs) were used to evaluate the complete response and no significant nausea. The results were separately analyzed for pure MEC regimens, carboplatin-based regimens and oxaliplatin-based regimens. RESULTS Ten trials focused on MEC involving 2928 cancer patients using NK-1RA triple regimens or conventional duplex regimen were included. NK-1RA-based triple regimen showed significant better complete responses in overall (RR: 1.14; 95% CI: 1.05-1.24), acute (RR: 1.02; 95% CI: 1.00-1.04) and delayed (RR: 1.13; 95% CI: 1.04-1.23) phase compared with duplex regimen in patients with MEC. Similar results were found for no significant nausea. Subgroup analyses showed that triple regimen showed superior antiemetic efficacy significantly in patients with carboplatin-based chemotherapy, instead of oxaliplatin-based chemotherapy. CONCLUSION NK-1RA is recommended to use in carboplatin-based chemotherapy, not oxaliplatin-based chemotherapy.

Olanzapine-Based Triple Regimens Versus Neurokinin-1 Receptor Antagonist-Based Triple Regimens in Preventing Chemotherapy-Induced Nausea and Vomiting Associated with Highly Emetogenic Chemotherapy: A Network Meta-Analysis. Oncologist 2018; 23:603-616.

Abstract
BACKGROUND The current antiemetic prophylaxis for patients treated with highly emetogenic chemotherapy (HEC) included the olanzapine-based triplet and neurokinin-1 receptor antagonists (NK-1RAs)-based triplet. However, which one shows better antiemetic effect remained unclear. MATERIALS AND METHODS We systematically reviewed 43 trials, involving 16,609 patients with HEC, which compared the following antiemetics at therapeutic dose range for the treatment of chemotherapy-induced nausea and vomiting: olanzapine, aprepitant, casopitant, fosaprepitant, netupitant, and rolapitant. The main outcomes were the proportion of patients who achieved no nausea, complete response (CR), and drug-related adverse events. A Bayesian network meta-analysis was performed. RESULTS Olanzapine-based triple regimens showed significantly better no-nausea rate in overall phase and delayed phase than aprepitant-based triplet (odds ratios 3.18, 3.00, respectively), casopitant-based triplet (3.78, 4.12, respectively), fosaprepitant-based triplet (3.08, 4.10, respectively), rolapitant-based triplet (3.45, 3.20, respectively), and conventional duplex regimens (4.66, 4.38, respectively). CRs of olanzapine-based triplet were roughly equal to different NK-1RAs-based triplet but better than the conventional duplet. Moreover, no significant drug-related adverse events were observed in olanzapine-based triple regimens when compared with NK-1RAs-based triple regimens and duplex regimens. Additionally, the costs of olanzapine-based regimens were obviously much lower than the NK-1RA-based regimens. CONCLUSION Olanzapine-based triplet stood out in terms of nausea control and drug price but represented no significant difference of CRs in comparison with NK-1RAs-based triplet. Olanzapine-based triple regimens should be an optional antiemetic choice for patients with HEC, especially those suffering from delayed phase nausea. IMPLICATIONS FOR PRACTICE According to the results of this study, olanzapine-based triple antiemetic regimens were superior in both overall and delayed-phase nausea control when compared with various neurokinin-1 receptor antagonists-based triple regimens in patients with highly emetogenic chemotherapy (HEC). Olanzapine-based triplet was outstanding in terms of nausea control and drug price. For cancer patients with HEC, especially those suffering from delayed-phase nausea, olanzapine-based triple regimens should be an optional antiemetic choice.
