BiCaZO: A Study Combining Two Immunotherapies (Cabozantinib and Nivolumab) to Treat Patients With Advanced Melanoma or Squamous Cell Head and Neck Cancer, an immunoMATCH Pilot Study
Recruiting
This phase II trial studies the good and bad effects of the combination of drugs called cabozantinib and nivolumab in treating patients with melanoma or squamous cell head and neck cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune...

Targeted Therapy to Increase RAI Uptake in Metastatic DTC
Recruiting
Papillary thyroid cancer (PTC) is a common type of differentiated thyroid cancer (DTC) in children and represents the second most common cancer in adolescent females. Recently targeted drugs that block many of the genetic drivers of DTC have become available. While Investigators know that these drugs shrink DTC tumors in many cases, the impact on radioactive iodine (RAI) avidity has not been systematically studied.

A Phase III Study to Investigate if the Study Drug Diamyd Can Preserve Insulin Production and Improve Glycemic Control in Patients Newly Diagnosed With Type 1 Diabetes
Recruiting
The objective of DIAGNODE-3 is to evaluate the efficacy and safety of three intranodal injections of 4 μg of Diamyd compared to placebo, along with oral Vitamin D supplementation, to preserve endogenous beta cell function and influence glycemic parameters in adolescent and adults recently diagnosed with T1D carrying the HLA DR3-DQ2 haplotype.

Combination Therapy for the Treatment of Diffuse Midline Gliomas
Recruiting
This phase II trial determines if the combination of ONC201 with different drugs, panobinostat or paxalisib, is effective for treating participants with diffuse midline gliomas (DMGs). Despite years of research, little to no progress has been made to improve outcomes for participants with DMGs, and there are few treatment options. ONC201, panobinostat, and paxalisib are all enzyme inhibitors that may stop the growth of tumor cells by clocking some of the enzymes needed for cell growth. This phas... Read More

Testing Combination Erdafitinib and Enfortumab Vedotin in Metastatic Bladder Cancer After Treatment With Chemotherapy and Immunotherapy
Recruiting
This phase Ib trial evaluates the best dose, potential benefits, and/or side effects of erdafitinib in combination with enfortumab vedotin in treating patients with bladder cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and possesses genetic alterations in FGFR2/3 genes. Erdafitinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal FGFR protein that signals cancer cells to multiply. Th... Read More
