- Brief Summary
This will be a phase 1, multicenter, open-label trial to evaluate the safety, tolerability, PK and efficacy of ZN-A-1041 as a monotherapy or in combination in patients with HER2-positive advanced solid tumors.
The study will consist of three phases: phase 1a (dose escalation with ZN-A-1041 monotherapy), phase 1b (dose escalation with ZN-A-1041 in combination with Capecitabine and Trastuzumab) and phase 1c (dose expansion with ZN-A-1041 in combination with Capecitabine and Trastuzumab).
- Detailed Description
Phase 1a of the study will adopt the "modified 3+3" dose escalation design with a total of 7 planned dose levels. Patients with HER2-positive advanced solid tumor (including those with brain metastases) will be enrolled to receive a single-dose administration of ZN-A-1041 followed by multiple-dose administration of ZN-A-1041.
Phase 1b of the study will adopt the "traditional 3+3" dose escalation design. In phase 1b, patients with HER2-positive advanced breast cancer (including those with brain metastases) will be enrolled to receive multiple doses of ZN-A-1041 in combination with Capecitabine and Trastuzumab.
In phase 1c patients with HER2-positive breast cancer with brain metastases were planned to be enrolled to receive ZN-A-1041 in combination with Capecitabine and Trastuzumab The dose levels will be determined based on the recommended doses obtained from the Phase 1b study, and the possible changes in the dosage form and the food effect study, which will be decided by the sponsor and the investigator after discussion.
Each phase of the study includes a screening period, a treatment period and a follow-up period. During the trial, the safety, tolerability, PK and efficacy data of ZN-A-1041 as monotherapy and in combination with Capecitabine and Trastuzumab in the subjects will be collected and analyzed, thereby providing RP2D for the subsequent clinical trials.

Group Intervention Description ZN-A-1041 MAD+Capecitabine 1000 mg/m2+Trastuzumab 8 mg/kg iv. First Cycle ZN-A-1041 MAD +Capecitabine 1000 mg/m2 + Trastuzumab 8 mg/kg iv. First Cycle Phase 1b: If the MTD is still not reached at the maximum dose level in Phase 1a study, the maximum dose level (MAD) of ZN-A-1041 in Phase 1a will be used in Phase 1b study. If intolerance, reduce Capecitabine dose to 750 mg/m2 for exploration ZN-A-1041 400mg ZN-A-1041 400mg BID Phase 1a: Subjects will be given ZN-A-1041 orally 400mg Bid, for 21days as one cycle ZN-A-1041 800mg ZN-A-1041 800mg BID Phase 1a: Subjects will be given ZN-A-1041 orally 800mg Bid, for 21days as one cycle ZN-A-1041 1000mg ZN-A-1041 1000mg BID Phase 1a: Subjects will be given ZN-A-1041 orally 1000mg Bid, for 21days as one cycle ZN-A-1041 100mg ZN-A-1041 100mg BID Phase 1a: Subjects will be given ZN-A-1041 orally 100mg Bid, for 21days as one cycle ZN-A-1041 200mg ZN-A-1041 200mg BID Phase 1a: Subjects will be given ZN-A-1041 orally 200mg Bid, for 21days as one cycle ZN-A-1041 600mg ZN-A-1041 600mg BID Phase 1a: Subjects will be given ZN-A-1041 orally 600mg Bid, for 21days as one cycle ZN-A-1041 50mg ZN-A-1041 50mg BID Phase 1a: Subjects will be given ZN-A-1041 orally 50mg Bid, for 21days as one cycle ZN-A-1041 level 2+Capecitabine 1000 mg/m2+ Trastuzumab 8 mg/kg iv. First Cycle ZN-A-1041 Level 2 +Capecitabine 1000 mg/m2 + Trastuzumab 8 mg/kg iv. First Cycle Phase 1b: ZN-A-1041 Level 2 ( dose of MTD) to be used in the combination therapy will be determined based on the MTD identified in the Phase 1a study. Capecitabine will be given at the dose of 1000 mg/m2, BID (2000 mg/m2/day), during the first 2 weeks of the 21-day treatment cycle. Trastuzumab (8 mg/kg in cycle 1 followed by 6 mg/kg beginning in cycle 2, administered as an IV infusion.
