The changing landscape of clinical trials for mitochondrial diseases: 2011 to present.

ABSTRACT: We reviewed the status of interventional clinical trials for primary mitochondrial diseases. Using national and international search engines, we found 48 randomized controlled trials (RCTs) registered as of May 15, 2019. Consilience between lay and professional mitochondrial disease communities to engage in RCTs has increased, as has progress in developing new disease and treatment biomarkers and potential therapies. The continued advancement of general knowledge of mitochondrial biology has fostered appreciation for the fundamental role mitochondria play in the etiopathology of other rare and common illnesses, emphasizing the therapeutic potential of mitochondrially-targeted small molecules for an increasing spectrum of human diseases.

Project description:BackgroundCardiometabolic disease is a clinical syndrome characterized by multiple metabolic disorders, with atherosclerosis as the core and cardiovascular and cerebrovascular events as the outcome. Drug research and development (R&D) in cardiometabolic diseases has grown rapidly worldwide. However, the development of cardiometabolic drug clinical trials in China remains unclear. This study aims to depict the changing landscape of drug clinical trials for cardiometabolic diseases in China during 2009-2021.MethodsThe detailed information of drug trials on cardiometabolic diseases registered in the National Medical Products Administration (NMPA) Registration and Information Disclosure Platform was collected between January 1, 2009, and July 1, 2021. The landscape of cardiometabolic drug clinical trials was analyzed by the characteristics, time trends, indications, pharmacological mechanisms, and geographical distribution.ResultsA total of 2466 drug clinical trials on cardiometabolic diseases were extracted and analyzed. The annual number of drug trials increased rapidly in the past twelve years. Among all the trials, the bioequivalence trials (1428; 58.3%) accounted for the largest proportion, followed by phase I (555; 22.5%), phase III (278; 11.3%), phase II (169; 6.9%), and phase IV (26; 1.1%). Of 2466 trials, 2133 (86.5%) trials were monomer drugs, only 236 (9.6%) trials were polypills and 97 (3.9%) were traditional Chinese medicine (TCM) compounds. In terms of pharmacological mechanisms, the number of trials in dihydropyridine (DHP) calcium antagonists 321 (11.9%) ranked first, while trials in angiotensin receptor blocker (ARB) 289 (10.7%) and dipeptidyl peptidase-4 (DPP-4) inhibitor 205 (7.6%) ranked second and third place respectively. Of 236 chemical polypills trials, 23 (9.7%) polypills were the combination of DHP calcium antagonists and statins, while others were the combination of two same pharmacological effect agents. As for the geographical distribution of leading units, 36 trials were led by principal investigators (PI) units from Beijing, followed by Jiangsu (n = 29), Shanghai (n = 19), Guangdong (n = 19), and Hunan (n = 19), showing an uneven regional distribution.ConclusionsGreat progress has been made in drug clinical trials on cardiometabolic diseases, especially in antihypertensive agents, hypoglycemic agents, and hypolipidemic agents. However, the insufficient innovation of first-in-class drugs and polypills should be carefully considered by all stakeholders in drug trials.

Project description:BackgroundIn recent years, new drug development on lung cancer is in full swing in China. The aim of this study was to overview the changing landscape of anti-lung cancer drug clinical trials in mainland China from 2005 to 2020.MethodsWe analysed anti-lung cancer drug clinical trials registered on three websites including the China National Medical Products Administration Centre for Drug Evaluation platform, the Chinese Clinical Trial Registry and ClinicalTrials.gov.FindingsA total of 1595 anti-lung cancer drug clinical trials from Jan 1st, 2005 to Dec 31st, 2020 were extracted, which included 630 (39•5%) investigator-initiated trials (IITs), 698 (43•8%) domestic industry-sponsored trials (ISTs), and 267 (16•7%) international ISTs. During the past 16 years, the number of anti-lung cancer clinical trials including IITs and domestic ISTs had a remarkable growth, however, the number of international ISTs increased slowly. The number of principal clinical trial units also increased significantly over time. Of the 1595 trials, the largest growth was observed in phase I trials during 2013-2020, with an average annual growth rate of 38•6%. 278 trials were led by principal investigators (PI) from Guangdong, followed by Beijing (n=273) and Shanghai (n=257). Among the 965 ISTs, clinical trials involving targeted drugs (588, 60•9%) accounted for the largest proportion, followed by immunotherapeutic drugs (284, 29•4%), cytotoxic drugs (75, 7•8%), and traditional Chinese medicine (18, 1•9%). In terms of targeted drugs, EGFR-TKIs remained the most studied drugs (225/588, 38•27%). As for immunotherapy, 125 out of 284 (44•01%) trials involved PD-1 inhibitors, 60 (21•13%) trials involved PD-L1 inhibitors, and seven (2•46%) trials involved CTLA-4 inhibitors.InterpretationIn the past 16 years, the development of anti-lung cancer drug clinical trials has achieved much progress in mainland China. The most progress lied in targeted therapy and immunotherapy.FundingThis work was financially supported in part by China National Major Project for New Drug Innovation (2017ZX09304015) and Chinese Academy of Medical Sciences (CAMS) Innovation Fund for Medical Sciences (CIFMS) (2016-I2M-1-001).
