First-in-Human Study of OKI-219 in Advanced Solid Tumors and Advanced Breast Cancer
Bu çalışma, PI3Kα H1047R mutasyonu taşıyan ileri evre solid tümörleri ve ileri evre meme kanseri (breast cancer) olan hastalarda OKI-219 adlı ilacın (tek başına ya da Fulvestrant, Trastuzumab, Tucatinib gibi ilaçlarla birlikte) güvenliliğini incelemektedir. Çalışmaya, en az bir ölçülebilir tümör lezyonu bulunan ve daha önce belirli tedavileri almış yetişkin hastalar alınmaktadır. Çalışma Faz 1 aşamasında yürütülmekte ve halen katılımcı almaktadır.

Additional Cohort-specific key inclusion criteria: Part A * Participants with HR+/HER2- locally advanced, unresectable or metastatic breast cancer, must have received at least 1 prior line of hormonal therapy and at least 1 prior line of CDK4/6-inhibitor in the advanced or metastatic setting. * Participants with HER2+ locally advanced, unresectable or metastatic breast cancer, must have received prior taxane, trastuzumab, pertuzumab, and tucatinib. Prior trastuzumab deruxtecan is allowed but not required. * Participants with HER2-low breast cancer must have received prior trastuzumab deruxtecan. * Participants with colorectal cancer must have KRAS wild-type disease. Part B * Participants with locally advanced, unresectable or metastatic HR+/HER2- breast cancer must have received at least 1 prior line of hormonal therapy in the advanced or metastatic setting and at least 1 prior CDK4/6-inhibitor. * Participants with HER2-low breast cancer should have received prior trastuzumab deruxtecan Part C ● Participants with HR±/HER2+ locally advanced, unresectable or metastatic breast cancer must have received prior taxane, trastuzumab, and pertuzumab unless unavailable in the region or contraindicated. Prior trastuzumab deruxtecan is allowed but not required. Part D ● Participants must have HR+/HER2- locally advanced, unresectable or metastatic breast cancer Part E ● Participants must have HR+/HER2- locally advanced, unresectable or metastatic breast cancer.
