New cancer drug OC-001 tested in advanced tumors – trial ends early

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Criteria: Inclusion Criteria: 1\. Have histological or cytological evidence of a diagnosis of selected cancer types that is locally advanced and/or metastatic 1.

Must have failed a previous immune checkpoint inhibitor. Must not have any history of tumors that test positive for epidermal growth factor receptor (EGFR), Receptor Tyrosine Kinase (ROS1), Anaplastic Lymphoma Kinase (ALK) mutations or ALK fusions or any other mutations for which tyrosine kinase inhibitors are available. * Renal Cell Carcinoma (RCC): Must have failed at least one prior systemic therapy. Must have failed a previous IO agent. * Urothelial Cancer: Must have failed at least one prior systemic therapy. Must have failed a previous IO agent. * Merkel Cell: Must have failed at least 1 prior systemic therapy for advanced disease and may have failed a previous IO agent. * Squamous Cell Carcinoma of the Skin: Must have failed at least 1 prior systemic therapy for advanced disease and may have failed a previous IO agent. 3\. Phase 1b - combination dose escalation: * Cervical Cancer Must have failed at least 1 chemotherapy regimen. * Bladder Cancer Must have failed a platinum-containing chemotherapy regimen. Must have failed a previous immune checkpoint inhibitor. * RCC Must have failed at least 1 prior systemic therapy. Must have failed a previous IO agent. * Urothelial cancer Must have failed at least 1 prior systemic therapy. Must have failed a previous IO agent. * Diffuse large B cell lymphoma Must have failed prior rituximab therapy. May have failed prior chemotherapy or other IO agents. * NSCLC Must have failed a single agent PD-1 or PD-L1 inhibitor as the last regimen and must have responded to the agent. * Must not have any history of tumors that test positive for EGFR, ROS1, ALK mutations or ALK fusions, or any other mutations for which tyrosine kinase inhibitors are available or are under development. 4\. For Phase 2a: Must have histological or cytological confirmation of a solid tumor that is locally advanced or metastatic. At least two cancer type will be selected amongst the ones evaluated in the Phase 1b combination dose escalation part of the study. 5\. Have adequate organ function 6 Have a performance status (PS) of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) scale 7 Have discontinued cytotoxic therapy, biologic therapy, immunotherapy, radiotherapy, and cancer-related hormonal therapy at least 21 days prior to study enrollment 8. Are recovered or recovering from the acute adverse effects of any chemotherapy, biologic, therapy, immunotherapy, cancer-related hormonal therapy, or radiotherapy 9. Patients who have had major surgery must be fully recovered and greater than (≥)4 weeks post-operative 10. Men with partners of child-bearing potential or women with child-bearing potential must agree to use a medically approved contraceptive method during and for at least 12 weeks following the last dose of study drug (e.g., intrauterine device (IUD), birth control pills, or barrier method) 11. Women of child-bearing potential must have a negative serum pregnancy test documented 12. Have an estimated life expectancy of at least 3 months Exclusion Criteria: 1. Have symptomatic central nervous system (CNS) metastasis. Patients with treated CNS metastases are eligible for this study if they are asymptomatic and off of corticosteroids for a minimum of 7 days.
