What this Trial Is About

Researchers are evaluating the safety and effectiveness of BL-M05D1 in patients with advanced gastric cancer or gastroesophageal junction adenocarcinoma that is positive for Claudin 18.2. This Phase III, randomized, open-label, multicenter trial focuses on patients who have already undergone prior first-line treatment and aims to compare BL-M05D1 with other common chemotherapy options. The study is led by Sichuan Baili Pharmaceutical Co., Ltd. and aims to provide new options for patients with these advanced cancers. Participants in this study will be randomly assigned to receive either BL-M05D1 or an investigator-chosen chemotherapy regimen which includes paclitaxel, docetaxel, or irinotecan hydrochloride. BL-M05D1 is given by intravenous infusion every 3 weeks. In the comparator group, paclitaxel is infused every 4 weeks, docetaxel every 3 weeks, and irinotecan hydrochloride every 2 weeks. Those who show clinical benefit may continue treatment for additional cycles until disease progression, intolerable side effects, or other reasons for stopping treatment occur. During the trial, participants will be closely monitored with assessments including overall survival and progression-free survival up to approximately 24 months. Other measures include response rates, duration of response, and treatment-related adverse events. Tumor tissue samples will be collected, and participants must have measurable lesions. Regular evaluations will help track the disease and safety of treatments. The study will last as long as needed to gather data, with safety and efficacy followed throughout and after treatment periods.

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

Treatment

Duration - Variable, based on individual response until disease progression or discontinuation

Participants receive intravenous drug treatment cycles. Participants in the experimental group receive BL-M05D1 every 3 weeks. Participants in the control group receive investigator's choice of paclitaxel every 4 weeks, docetaxel every 3 weeks, or irinotecan hydrochloride every 2 weeks. Treatment continues until disease progression, intolerable toxicity, or other reasons.

Repeated visits for each treatment cycle (every 2 to 4 weeks depending on assigned treatment)
