In June 2023, the product's new indication was re approved by the FDA for the treatment of mCRPC patients with HRR gene mutations in combination with enzalutamide. In a phase 3 TALAPRO-2 trial targeting mCRPC patients, a favorable overall survival (OS) trend was observed with the combination therapy of talazolparib, along with statistically and clinically significant rPFS data. Compared with placebo combined with enzalutamide, the combination therapy of talazolparib reduced the risk of disease progression or death in mCRPC patients by 55%.
3. Beierda Pharmaceutical's third-generation EGFR inhibitor approved for new indications in China

According to the official website of Beierda Pharmaceutical, the newly approved indication for this drug is first-line NSCLC. According to a previous study published in BMC Medicine, a phase 2a clinical trial evaluated the efficacy and safety of remitinib as first-line treatment for locally advanced or metastatic/recurrent EGFR mutant NSCLC patients. The study included 43 patients, and as of the data deadline of December 23, 2021, the ORR assessed by BICR was 83.7%; The median DoR is 19.3 months. The median PFS assessed by BICR and researchers were 20.7 months and 22.0 months, respectively. The data about OS is not yet mature.
4. Nivolumab approved as first-line treatment for urothelial carcinoma in China

This approval is based on positive data from the Phase III study CheckMate-901. Data shows that at a median follow-up of approximately 33 months, patients receiving combination chemotherapy with oxaliplatin and sequential monotherapy with oxaliplatin had an overall survival rate of 21.7 months (18.9 months in the chemotherapy group), significantly reducing the risk of death by 22% (HR=0.78, p=0.0171); The median PFS was 7.9 months (7.6 months in the chemotherapy group), significantly reducing the risk of disease progression or death by 28% (HR=0.72, p=0.0012). In terms of treatment response, the combination of Odiwo and chemotherapy also showed clinically significant improvements: ORR reached 57.6% (chemotherapy group 43.1%); 21.7% of patients achieved CR, which is nearly twice the proportion of the chemotherapy group (11.8%); And the median duration of CR can reach 37.1 months, which is nearly three times longer than the chemotherapy group (13.2 months).
