Characteristics of clinical trials of new oncology drugs approved in China.

BACKGROUND: Since reforms were introduced to incentivize drug innovation in 2015, the Chinese pharmaceutical market has experienced unprecedented prosperity, with more new drugs than ever before, especially anticancer treatments. In 2021, Chinese regulatory agencies issued the new guideline for clinical research and development of antitumor drugs, triggering a series of responses on the drug market. Limited research has outlined the nature of the original new drugs in China to understand the dynamic response of the market. METHODS: The objective of this article was to map the clinical development of approved new oncology drugs in China from 2015 to 2021 and differed from previous studies by focusing on original new drugs, using the United States as a benchmark, and elaborating the endogenous features of clinical trials. RESULTS: Clinical trials conducted in China have risen to a level similar to that of the United States in many aspects of trial design, but there is still distance between the implementation and operational details of clinical trials. In the meantime, China has made significant breakthroughs in drug approval. Greater than 60% of novel anticancer drugs in China received accelerated approved for their first listing. Approximately 90% of the pivotal clinical trials supporting initial drug approval used surrogate measures as end points, and one half were nonrandomized or did not have a control group. However, duplicate development without evidence of a clinical advantage compared with current therapies was widely observed. CONCLUSIONS: By presenting a multidimensional landscape of clinical trials and approvals in the real world, this review allows interested researchers, developers, and even regulators to understand what has been done and what should be done next in anticancer drug development in China.

Characteristics and use of patient-reported outcomes of clinical trials for high-risk neurological medical devices that received FDA premarket approval from 2001 to 2022.

Neurological medical devices have revolutionized the management of neurological disorders, providing diagnostic, therapeutic, and monitoring solutions. High-risk neurological devices, such as deep brain stimulation and neurostimulators, offer groundbreaking treatments, emphasizing patient benefits while considering risks. To gain FDA approval, high-risk Class III devices necessitate premarket approval (PMA) applications with pivotal clinical trials, often assessing patient-reported outcomes (PROs). This article analyzes FDA-approved high-risk neurological devices from 2001 to 2022 via the PMA pathway. It explores device characteristics and pivotal clinical trials, and PRO incorporation. Of the 23 identified devices, pain neurology devices (30.4 %) predominated. All devices were therapeutic, with varying study designs. Pain neurology devices notably emphasized PRO endpoints as expected. This study underscores the significance of PROs in assessing device efficacy and safety, offering insights into regulatory processes and patient-centered care in neurological disorder management.
