This study sought to systematically evaluate the characteristics of the innovative drugs approved in China. The cross-sectional study included all innovative small molecules that submitted a marketing application after 2016 and were approved by the NMPA before 2024, as well as all innovative biologics and Chinese medicines that submitted after 2020 and were approved before 2024. Based on the NMPA's open databases, information on each drug and its pivotal trial was collected. A total of 167 innovative drugs were approved, consisting of 58.1% small molecules, 31.1% biologics, and 10.8% Chinese medicines. The domestic drugs dominated (86.8%) and continued to grow from 2018 to 2024. The drugs were concentrated in the oncology area (43.7%), particularly in biologics (55.8%). Most oncology drugs (90.4%) were approved based on surrogate end-point evidence. Chinese medicines received much less regulatory flexibility than small molecules/biologics. The expedited programs helped accelerate the clinical development and review processes. However, the review time tended to exceed the stipulated timeframes. The great efforts of the Chinese regulator and industry in nurturing innovation are bearing fruit. More investments from the regulator and drug developers are needed to focus on R&D in differentiated therapies, financial incentives and regulatory priorities for high-quality innovations, along with review capacity improvements, in order to facilitate an innovation-driven and internationally competent pharmaceutical industry in China.</p>","PeriodicalId":153,"journal":{"name":"Clinical Pharmacology & Therapeutics","volume":" ","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identifying effective sequential therapies after denosumab discontinuation is crucial to mitigate these risks. We conducted the Denosumab Sequential Therapy (DST) trial, a two-year, multicenter, open-label, randomized controlled trial, conducted at a referral center and two affiliated hospitals in Taiwan. The DST trial enrolled 101 patients aged 50 years or older who received denosumab for at least 2 years (median: 2 years) and stratified the patients into four intervention groups to evaluate the effectiveness of three therapeutic strategies compared to continuous denosumab treatment. The four arms were as follows: (1) continued denosumab for 2 years (denosumab group); (2) two consecutive annual zoledronate infusions (annual-zoledronate group); (3) one zoledronate infusion followed by a supervised medication-free year (biennial-zoledronate group); and (4) one zoledronate infusion followed by resumed denosumab (double-switching group). The primary outcome was the percent change in the lumbar spine (LS) bone mineral density (BMD), total hip BMD (TH-BMD), and femoral neck BMD (FN-BMD). Secondary outcomes included changes in BTMs, the incidence of clinical fractures, and the need for rescue zoledronate in the biennial-zoledronate group.

One-third of patients in the biennial-zoledronate group showed LS-BMD loss exceeding the least significant change (LSC), and 22% required rescue zoledronate infusions. Given the significant bone loss observed, a single zoledronate infusion followed by a medication-free year is not recommended.

Preclinical evidence suggests MEZI is primarily metabolized by cytochrome P450 (CYP) 3A4/5 and has the potential to inhibit efflux transporters P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) in vitro. To predict the magnitude of enzyme- and transporter-mediated drug-drug interactions (DDI) and inform clinical study design, a physiologically based pharmacokinetic (PBPK) model was developed. A PBPK-informed Phase I clinical DDI study was conducted that evaluated MEZI as an object of CYP3A induction (rifampin) and inhibition (itraconazole) and as a precipitant of transporter-mediated interactions (digoxin and rosuvastatin). PBPK modeling predicted substantial interactions with strong and moderate CYP3A modulators, which informed a unique dose selection strategy, PK sampling time, and washout period. Clinical results confirmed reductions in MEZI exposure with rifampin (AUC reduced 93-95%) and increases with itraconazole (~14-fold for dose normalized AUC). MEZI was well-tolerated despite these changes in exposure. Additionally, coadministration of MEZI with P-gp and BCRP substrates, digoxin and rosuvastatin, showed no clinically meaningful changes in substrate plasma PK, indicating a low likelihood of significant transporter-mediated DDIs. The prospective PBPK model was refined with clinical data, improving predictions and supporting simulations for moderate/weak CYP3A modulators. This iterative \"learn-confirm\" approach underscores the utility of PBPK modeling in optimizing clinical trial design, ensuring participant safety, and anticipating DDI risks. The findings support MEZI's clinical development with informed dosing strategies, particularly for coadministration with CYP3A modulators.</p>","PeriodicalId":153,"journal":{"name":"Clinical Pharmacology & Therapeutics","volume":" ","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145243359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drug repositioning strategy of Pegbing® from CHB to ET aims to accelerate development and reduce costs. Through the application of pharmacometrics, the existing data from CHB patients were leveraged to inform dose selection and clinical trial design for ET patients.

According to the parameter distribution and correlation from the extrapolated PK/PD relationship, 1,000 virtual ET patients were generated to form an in silico clinical trial, revealing that baseline PLT and WBC levels were key factors for hematologic response.

We also evaluated combinations of up to four drugs and identified associations at the ATC level of drug class(es). In this study, we reproduced several known adverse drug events and protective drug effects, while some associations were attributable to confounding, mutual indications, or reverse causation.

In this paper, insights from multiple formal regulatory interactions related to the RADIAL trial, conducted between 2021 and 2022, are presented. These interactions included (i) a consultation with the European Medicines Agency's Innovation Task Force, (ii) a national Scientific Advice procedure, and (iii) the clinical trial application submission under the EU Clinical Trials Regulation (Regulation EU 536/2014). Given the novelty of the decentralized approach and lack of guidelines, many constructive comments and questions were received that supported the finalization of the protocol and conduct of the trial. It is important to acknowledge that clinical trials often span multiple countries and regulatory jurisdictions, creating complexity due to variations in complementary national legal and regulatory requirements. We conclude that early and continuous regulatory engagement is essential for the successful implementation of innovative trial designs.
