Filter by:Study CP-MGC018-03 is an open-label, two-part, Phase 2 study. Part 1 of the study will enroll participants with metastatic castration-resistant prostate cancer (mCRPC) previously treated with one prior androgen receptor axis-targeted therapy (ARAT). ARAT includes abiraterone, enzalutamide, or apalutamide. Participants may have received up to 1 prior docetaxel-containing regimen, but no other chemotherapy agents. This part of the study will assess the efficacy and tolerability of vobramitamab duocarmazine (MGC018) in two experimental arms (2.0 mg/kg every 4 weeks [Q4W] and 2.7 mg/kg Q4W) . Approximately 100 participants will be randomized 1:1. Part 2 of the study will enroll participants with locally advanced or metastatic squamous cell carcinoma (SCC) of the anus, melanoma, head and neck squamous cell carcinoma (HNSCC), squamous non-small cell lung carcinoma (NSCLC), and small cell lung carcinoma (SCLC). Participants must have progressive following at least 1 prior line of standard chemotherapy for advanced or metastatic disease. Participants will receive vobramitamab docarmazine at a dose of 2.7 mg/kg every 4 weeks. Up to 200 participants may be enrolled in Part 2. In both parts, vobramitamab duocarmazine will be administered intravenously (IV) in clinic on Day 1 of each 4-week cycle. Vobramitamab duocarmazine will be administered for up to 26 cycles, approximately 2 years, until criteria for treatment discontinuation are met. Participants will undergo regular testing for signs of disease progression using computed tomography (CT) scans, magnetic resonance imaging (MRI), bone scans, and prostate-specific antigen (PSA) blood tests. Routine examinations and blood tests will be performed and evaluated by the study doctor.
Despite the low androgen receptor (AR) transcriptional activity of treatment-emergent small cell neuroendocrine prostate cancer, there is persistent AR expression observed in the majority of treatment-emergent small-cell neuroendocrine prostate cancer (t-SCNC) biopsies. This indicates that epigenetic dysregulation leads to reprogramming away from an AR-driven transcriptional program. Therefore, continuation of AR blockade in the form of apalutamide may provide additive benefit compared to immune checkpoint blockade alone. The investigators hypothesize that the combination of apalutamide plus cetrelimab will achieve a clinically significant composite response rate with sufficient durability of response in mCRPC patients with evidence of treatment-emergent small cell neuroendocrine prostate cancer
An open-label, multicenter, Phase 1b/2 study to identify the recommended Phase 2 dose and assess the efficacy and safety of BXCL701 administered orally, as monotherapy and in combination with PEMBRO, in patients with mCRPC. Patients enrolled in the Phase 2a portion of the study will have either Small Cell Neuroendocrine Prostate Cancer(SCNC)(Cohort A) or adenocarcinoma phenotype (Cohort B), while the Phase 2b randomized portion of the study will enroll only the histologic subtype(s) showing preliminary evidence in Phase 2a. The study will also assess other efficacy parameters, such as rPFS, PSA PFS, OS, and DOR, as well as the safety of the combined treatment. The study will consist of three components.
This phase II trial studies how well pembrolizumab works in treating patients with rare tumors that cannot be removed by surgery or have spread to other parts of the body. Monoclonal antibodies, such as pembrolizumab, may block specific proteins found on white blood cells which may strengthen the immune system and control tumor growth.
