Testing the Addition of an Anti-cancer Drug, DT2216, to the Usual Chemotherapy Treatment for Relapsed or Refractory Solid Tumors and Fibrolamellar Carcinoma
Recruiting
This phase I/II trial tests the safety, side effects and best dose of DT2216 in combination with irinotecan and how well it works in treating children, adolescents and young adults with solid tumors and fibrolamellar cancer that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). DT2216 is an anti-apoptotic protein B-cell lymphoma-extra large targeted protein degrader. It may stop the growth of tumor cells by blocking Bcl-xL, a pro... Read More

Testing the Role of DNA Released From Tumor Cells Into the Blood in Guiding the Use of Immunotherapy After Surgical Removal of the Bladder, Kidney, Ureter, and Urethra for Urothelial Cancer Treatment, MODERN Study
Recruiting
This phase II/III trial examines whether patients who have undergone surgical removal of bladder, kidney, ureter or urethra, but require an additional treatment called immunotherapy to help prevent their urinary tract (urothelial) cancer from coming back, can be identified by a blood test. Many types of tumors tend to lose cells or release different types of cellular products including their DNA which is referred to as circulating tumor DNA (ctDNA) into the bloodstream before changes can be seen...

A Study to Evaluate Next-Generation Sequencing (NGS) Testing and Monitoring of B-cell Recovery to Guide Management Following Chimeric Antigen Receptor T-cell (CART) Induced Remission in Children and Young Adults With B Lineage Acute Lymphoblastic Leu...
Recruiting
Background: Chimeric antigen receptor T-cell (CART) therapy is a form of immunotherapy which can be used to treat people with relapsed B-ALL. For those who achieve remission after CART alone, it may cure up to 50% of people who receive this therapy. However, for people who relapse after CART, it can be hard to achieve remission again. In patients where CART fails, stem cell transplant (HCT) can be used to prevent relapse and achieve cure. But HCT can cause serious side effects. Better testing i... Read More

Tiragolumab and Atezolizumab for the Treatment of Relapsed or Refractory SMARCB1 or SMARCA4 Deficient Tumors
Recruiting
This phase I/II trial studies how well tiragolumab and atezolizumab works when given to children and adults with SMARCB1 or SMARCA4 deficient tumors that have either come back (relapsed) or do not respond to therapy (refractory). SMARCB1 or SMARCA4 deficiency means that tumor cells are missing the SMARCB1 and SMARCA4 genes, seen with some aggressive cancers that are typically hard to treat. Immunotherapy with monoclonal antibodies, such as tiragolumab and atezolizumab, may help the body's immune... Read More

This phase II trial studies whether adding pembrolizumab to olaparib (standard of care) works better than olaparib alone in treating patients with pancreatic cancer with germline BRCA1 or BRCA2 mutations that has spread to other places in the body (metastatic). BRCA1 and BRCA2 are human genes that produce tumor suppressor proteins. These proteins help repair damaged deoxyribonucleic acid (DNA) and, therefore, play a role in ensuring the stability of each cell's genetic material. When either of t... Read More
