這是一項 CGT9486 聯合 sunitinib 的第三期、開放標籤、國際、多中心研究。這是一項多部分研究,將納入約 482 名患者。第一部分包含兩項評估:1)在約 20 名已接受至少一線治療的胃腸道基質瘤(GIST)患者中,確認將用於後續部分的 CGT9486 更新配方的劑量;以及 2)評估其潛在
適應症:Advanced Gastrointestinal Stromal Tumors、Metastatic Cancer
收案條件
納入條件
- Histologically confirmed locally advanced, metastatic, and/or unresectable GIST. Molecular pathology report must be available for Part 2; if molecular pathology report is unavailable or inadequate, an archival or fresh tumor tissue sample will be required to evaluate mutational status prior to randomization. (GIST 1L Substudy: must have documented mutation in KIT Exon 9 with an available molecular pathology report; archival or fresh tumor tissue sample will be required)

- Subjects must have received the following treatment:
- DDI Substudy/Part 1a: Treatment with ≥1 prior lines of therapy for GIST
- Part 1b: Treatment with ≥2 prior TKI for GISTs
- Part 2: Prior treatment with imatinib only
- GIST 1L Substudy: No prior systemic therapy for GIST including adjuvant therapy. Exception: up to 10 subjects with ongoing imatinib therapy of ≤4 weeks
- Have at least 1 measurable lesion according to mRECIST v1.1 (Part1a, Part 1b, Part 2, GIST 1L Substudy)
