Phase 1 Study of Mevrometostat for Treating RelapsedRefractory Small Cell Lung Cancer, Castration Resistant Prostate Cancer, and Follicular Lymphoma

What this Trial Is About

Researchers are studying the safety and effects of a medicine called Mevrometostat for treating three types of cancer RelapsedRefractory Small Cell Lung Cancer SCLC, Castration Resistant Prostate Cancer CRPC, and Follicular Lymphoma FL. This study is a Phase 1 trial that includes three parts, with Parts 1 and 2 now closed for enrollment. The current enrollment is open for men with CRPC who have previously been treated and whose disease has progressed since their last treatment. The purpose is to evaluate how Mevrometostat works alone or combined with other treatments in these cancers. The study involves giving Mevrometostat by mouth either alone or with other drugs such as Enzalutamide and Itraconazole, depending on the specific part or cohort. Part 3 consists of two substudies a Bioequivalence BE substudy where participants take three single doses of two Mevrometostat formulations over three periods, and a Drug-Drug Interaction DDI substudy with two cohorts receiving Mevrometostat alone or combined with Enzalutamide andor Itraconazole. After these assessment phases, participants enter a maintenance phase where they take Mevrometostat twice daily and Enzalutamide once daily until the cancer no longer responds. During the study, participants will be closely monitored for safety, including adverse events, laboratory tests, and vital signs over about two years. The researchers will also assess how well the drug works by measuring cancer response and progression-free survival. Pharmacokinetic studies will track how the drug behaves in the body. Patient experiences and symptoms will be evaluated through questionnaires. Overall, participants can expect regular visits to receive the study drugs, undergo testing, and provide feedback throughout their participation, which may last until disease progression or study completion.
