Nemiralisib is a potent anti-inflammatory agent for the treatment of chronic obstructive pulmonary disease (COPD) and other inflammatory lung diseases. The Cytochrome P450 3A4 (CYP3A4) is a major route of clearance for nemiralisib. The co-administration of drug therapies, which modulate CYP3A4, may alter the exposure of nemiralisib. Hence, this clinical drug interaction study with itraconazole (a potent CYP3A4 inhibitor) is required. The study will evaluate the PK, safety and tolerability of nemiralisib when administered alone and when administered concomitantly with repeat doses of itraconazole in healthy males and females. Subjects will receive treatment with nemiralisib alone in Period 1 and itraconazole followed by nemiralisib in Period 2 in single sequence crossover manner. Approximately 20 subjects will be enrolled such that approximately 16 evaluable subjects complete the study. Each subject will participate in the study for approximately 7 weeks including screening visit, 2 treatment periods and a follow up visit.

How to Design an Inhaled Drug: CHF-6523

Article

Author: Perry, Matthew W. D.

Inhalation provides an opportunity to target drugs to the lung, potentially improving efficacy and safety margins for the treatment of respiratory conditions. The discovery of inhaled medicines is a specialized endeavor and has different challenges to medicinal chemistry for oral drugs. The appearance of a successful campaign delivering an inhaled PI3Kδ inhibitor is therefore an opportunity to highlight how a team can address the challenges involved in the identification of such a compound. This Viewpoint seeks to highlight a great example of medicinal chemistry in the inhaled space.

Prediction of Inhibitory Activity against the MATE1 Transporter via Combined Fingerprint- and Physics-Based Machine Learning Models

Article

Author: Sasaki, Shunta ; Bender, Andreas ; Iijima, Takeshi ; Kageyama, Michiharu ; Asano, Satoshi ; Handa, Koichi

Renal secretion plays an important role in excretion of drug from the kidney. Two major transporters known to be highly involved in renal secretion are MATE1/2 K and OCT2, the former of which is highly related to drug-drug interactions. Among published in silico models for MATE inhibitors, a previous model obtained a ROC-AUC value of 0.78 using high throughput percentage inhibition data [J. Med. Chem. 2013, 56(3), 781-795] which we aimed to improve upon here using a combined fingerprint and physics-based approach. To this end, we collected 225 publicly available compounds with pIC50 values against MATE1. Subsequently, on the one hand, we performed a physics-based approach using an Alpha-Fold protein structure, from which we obtained MM-GB/SA scores for those compounds. On the other hand, we built Random Forest (RF) and message passing neural network models using extended-connectivity fingerprints with radius 4 (ECFP4) and chemical structures as graphs, respectively, which also included MM-GB/SA scores as input variables. In a five-fold cross-validation with a separate test set, we found that the best predictivity for the hold-out test was observed in the RF model (including ECFP4 and MM-GB/SA data) with an ROC-AUC of 0.833 ± 0.036; while that of the MM-GB/SA regression model was 0.742. However, the MM-GB/SA model did not show a dependency of the performance on the particular chemical space being predicted. Additionally, via structural interaction fingerprint analysis, we identified interacting residues with inhibitor as identical for those with noninhibitors, including substrates, such as Gln49, Trp274, Tyr277, Tyr299, Ile303, and Tyr306. The similar binding modes are consistent with the observed similar IC50 value inhibitor when using different substrates experimentally, and practically, this can release the experimental scientists from bothering of selecting substrates for MATE1. Hence, we were able to build highly predictive classification models for MATE1 inhibitory activity with both ECFP4 and MM-GB/SA score as input features, which is fit-for-purpose for use in the drug discovery process.

Efficacy of Nemiralisib in Chronic Obstructive Pulmonary Disease: A Systematic Review

Review

Author: Liang, Linbao ; Yang, Hongkuan ; Pan, Junjie ; He, Shuifeng

PURPOSE:

Chronic obstructive pulmonary disease (COPD) is a major public health concern. Exacerbation of COPD leads to poor health and frequent episodes of increased systemic and airway inflammation. Immunomodulatory drugs have garnered extensive attention because they may reduce the rate of COPD exacerbation. This review aimed to evaluate the efficacy and safety of nemiralisib in COPD patients.

METHODS:

Medical databases, including the Cochrane Library, EMBASE, and PubMed, were queried from inception to June 2023 to identify randomized controlled trials (RCTs) on the efficacy of nemiralisib in COPD patients. This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The Cochrane Collaboration tool was used to assess the risk of bias of the included RCTs. Two authors independently conducted literature screening and data extraction. Key information from the included studies was extracted, tabulated, and compared using a data extraction table. Moreover, the key characteristics, quality, potential bias, and endpoint outcomes of the included studies were summarized. A meta-analysis was conducted when the study outcomes were sufficiently comparable, and the required data were available for extraction.

FINDINGS:

Initially, 48 references were identified, leading to the inclusion of four trials. No significant difference was found between the nemiralisib and placebo groups in St George's Respiratory Questionnaire score, modified Medical Research Council Dyspnea Scale score, COPD Assessment Test score, time to next on-treatment exacerbation, proportion of patients achieving exacerbation recovery, time to exacerbation recovery, and rescue medication use. Contrastingly, the results demonstrated that nemiralisib may lower oral corticosteroid use during acute exacerbation of COPD. Meanwhile, the efficacy of nemiralisib on the exacerbation rate, as well as several parameters associated with lung function, including forced expiratory volume in 1 second, specific airway conductance, specific imaging airway wall thickness, distal specific imaging airway volume measured at functional residual capacity, specific imaging airway resistance, low attenuation score, and internal airflow lobar distribution in the lower pulmonary region, were conflicting. Attributed to the limited number of included RCTs and insufficient extracted data, it was not feasible to conduct a comprehensive meta-analysis.

IMPLICATIONS:

Because of insufficient data, this systematic review could not make any definitive statement regarding the efficacy of nemiralisib in COPD patients. In terms of safety, nemiralisib was generally well tolerated. Further trials are required to explore the efficacy of this drug.

GSK Cuts Six Respiratory Assets as It Continues to Focus on Oncology Treatments

Courtesy of Willy Barton/Getty Images GlaxoSmithKline has been in the midst of a significant reshaping to focus on pharmaceuticals, particularly a renewed interest in oncology treatments. As a result, the company has made some cuts to its pipeline, including six quietly announced this morning in the company’s year-end report. Willy Barton / Shutterstock.com GlaxoSmithKline has been in the midst of a significant reshaping to focus on pharmaceuticals, particularly a renewed interest in oncology treatments. As a result, the company has made some cuts to its pipeline, including six quietly announced this morning in the company’s year-end report. In a slide-show of graphics used during a conference call with analysts and media members, the company revealed it had terminated eight programs, mostly in its respiratory line. In the small section marked “terminated,” GSK said it shed two treatments for chronic obstructive pulmonary disease, GSK1325756 (danirixin) and GSK2269557 (nemiralisib). It also cut GSK2245035, a TLR7 agonist used for treating asthma and the TRPV4 antagonist GSK2798745, under development for acute respiratory distress syndrome and cough. Additionally, the company cut the combination treatment of GSK2398852 + GSK2315698 (anti-SAP) in transthyretin cardiomyopathy (ATTR-CM) and GSK3008348, an aVb6 antagonist for the treatment of idiopathic pulmonary fibrosis. The respiratory asset cuts are not much of a surprise, as the company has increasingly focused its resources on oncology treatments. In October, Alex Hoos, head of oncology at GSK, indicated that the company was shifting away from its respiratory base due to increased competition and loss of patent exclusivity. In an interview with S&P Global Market Intelligence , Hoos said the company could narrow its drug development focus to aim at products that will generate growth. The Hoos announcement followed the long-term plan for R&D unveiled over the summer by GSK Chief Science Officer and head of R&D, Hal Barron. The company said it will focus on the development of medicines that target mechanisms of action with strong human genetic validations. Those targets have a higher probability of success, which means a shift to a genetics-driven portfolio, the company said. Since taking over the helm of GSK, Chief Executive Officer Emma Walmsley has been driving the company toward its new focus and has reshaped her executive leadership and made several significant deals to support the plan. Among the deals made by GSK, was the December 2018 decision to put down $5.1 billion to acquire Tesaro and its PARP inhibitor, Zejula, which is used as maintenance treatment for ovarian cancer. Barron has touted the belief in PARP inhibitors that “that have been underappreciated in terms of the impact they can have on cancer patients.” More recently, GSK struck a deal with Merck KGaA, Darmstadt, Germany to collaborate on the development and potential commercialization of M7824 , an immunotherapy for difficult to treat cancers. M7824 is an investigational bifunctional fusion protein immunotherapy that has the potential to be a treatment for difficult-to-treat cancers including non-small cell lung and biliary tract cancers. Barron said the alliance with Merck KGaA is an “opportunity to further accelerate our oncology strategy.” In its announcement today, GSK noted that in its oncology pipeline, it has 16 oncology assets in clinical development with a potential for three launches by 2020. In July of 2018, the company only had eight oncology assets in clinical development. The doubling of the number of assets over the past eight months demonstrated the company’s discipline in building its oncology program. Over the course of the next year, the U.K.-based company said it will strengthen its oncology pipeline as it anticipates several key data readouts this year, including one with Zejula as first-line maintenance therapy in ovarian cancer. GSK is also anticipating a respiratory readout this year, its CAPTAIN study of Trelegy, which it expects will support regulatory submission.
