Recruiting now · Phase 1/Phase 2

Conditions studied: Advanced Solid Tumor

In brief

This is a phase I/II study to preliminarily explore of the safety, tolerability, pharmacokinetics, and efficacy of WJB001 combination therapy, consisting of three stages: Dose escalation (Phase Ia), dose extension (Phase Ib), and efficacy extension (Phase II). The preliminary plan includes seven combination therapy regimens, namely Arm A: WJB001+taxanes (A1: WJB001+paclitaxel, A2: WJB001+albumin paclitaxel); Arm B: WJB001+platinum (B1: WJB001+carboplatin, B2: WJB001+nedaplatin); Arm C: WJB001+paclitaxel+carboplatin; Arm D: WJB001+PARP inhibitor; Arm E: WJB001+VEGF inhibitor; Arm F:WJB001+JS207/JS001（F1：WJB001+JS207，F2：WJB001+JS001）；Arm G：WJB001+JS207/JS001+paclitaxel+carboplatin（G1: WJB001+JS207 +paclitaxel+carboplatin；G2：WJB001+JS001+paclitaxel+carboplatin）.
