Testing the Effectiveness of an Anti-cancer Drug, Triapine, When Used With Targeted Radiation-based Treatment (Lutetium Lu 177 Dotatate), Compared to Lutetium Lu 177 Dotatate Alone for Metastatic Neuroendocrine Tumors
Recruiting
This phase II trial compares the effect of adding triapine to lutetium Lu 177 dotatate versus lutetium Lu 177 dotatate alone (standard therapy) in shrinking tumors or slowing tumor growth in patients with neuroendocrine tumors that have spread from where they first started (primary site) to other places in the body (metastatic). Triapine may stop the growth of tumor cells by blocking some of the enzymes needed for deoxyribonucleic acid synthesis and cell growth. Lutetium Lu 177 dotatate is a rad... Read More

A Study to Compare Standard Therapy to Treat Hodgkin Lymphoma to the Use of Two Drugs, Brentuximab Vedotin and Nivolumab
Recruiting
This phase III trial compares the effect of adding immunotherapy (brentuximab vedotin and nivolumab) to standard treatment (chemotherapy with or without radiation) to the standard treatment alone in improving survival in patients with stage I and II classical Hodgkin lymphoma. Brentuximab vedotin is in a class of medications called antibody-drug conjugates. It is made of a monoclonal antibody called brentuximab that is linked to a cytotoxic agent called vedotin. Brentuximab attaches to CD30 posi... Read More

ONC-392 Versus Docetaxel in Metastatic NSCLC That Progressed on PD-1/PD-L1 Inhibitors
Recruiting
The goal of this Phase 3 clinical trial is study the safety and efficacy of the nextgen anti-CTLA-4 antibody, gotistobart (ONC-392/BNT316), in patients with metastatic non-small cell lung cancer who have disease progressed on anti-PD-1/PD-L1 antibody based therapy. The study will test whether gotistobart, in comparison with chemotherapy agent docetaxel, could prolong the life for NSCLC patients. Patients will be randomized to be treated with either gotistobart or docetaxel, IV infusion, once eve... Read More
