Attention Bias Modification for the Improvement of Anxiety in Adolescent and Young Adult Cancer Survivors
NCT06682039
Recruiting
This clinical trial studies how well attention bias modification (ABM) improves anxiety in adolescent and young adult (AYA) cancer survivors. Cancer-related anxiety is the most prevalent mental health problem affecting AYA cancer survivors. Cancer-related anxiety is associated with long-term negative outcomes such as poor quality of life, depression, distress, substance use, sleep problems, fatigue, and pain. ABM uses techniques to help patients change the way they react to environmental trigger... Read More

Testing the Addition of a Type of Drug Called Immunotherapy to the Usual Chemotherapy Treatment for Non-small Cell Lung Cancer, an ALCHEMIST Treatment Trial (Chemo-IO [ACCIO])
NCT04267848
Recruiting
This phase III ALCHEMIST treatment trial tests the addition of pembrolizumab to usual chemotherapy for the treatment of stage IIA, IIB, IIIA or IIIB non-small cell lung cancer that has been removed by surgery. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, pemetrexed, carboplatin, gemcitabine hydrochloride, and paclita... Read More

A Study of Ripretinib vs Sunitinib in Patients With Advanced GIST With Specific KIT Exon Mutations Who Were Previously Treated With Imatinib
NCT05734105
Recruiting
This is a Phase 3, 2-arm, randomized, open-label, global, multicenter study comparing the efficacy of ripretinib to sunitinib in participants with GIST who progressed on first-line treatment with imatinib, harbor co-occurring KIT exons 11+17/18 mutations, and are without KIT exon 9, 13, or 14 mutations. Upon disease progression as determined by an independent radiologic review, participants randomized to sunitinib will be given the option to either crossover to receive ripretinib 150 mg QD or di...

Testing the Addition of Pembrolizumab, an Immunotherapy Cancer Drug to Olaparib Alone as Therapy for Patients With Pancreatic Cancer That Has Spread With Inherited BRCA Mutations
NCT04548752
Recruiting
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

Fecal Microbiota Transplant and Dietary Fiber Supplementation for the Treatment of Gut Graft Versus Host Disease
NCT05067595
Recruiting
This phase I trial studies how well fecal microbiota transplant and dietary fiber supplementation work in treating patients with gut graft versus host disease. Fecal microbiota transplant entails inoculating donor stool into a recipient's gastrointestinal tract.

Testing the Addition of an IDH2 Inhibitor, Enasidenib, to Usual Treatment (Cedazuridine-Decitabine) for Higher-Risk Myelodysplastic Syndrome (MDS) With IDH2 Mutation (A MyeloMATCH Treatment Trial)
NCT06577441

This phase II MyeloMATCH treatment trial compares the usual treatment of cedazuridine-decitabine (ASTX727) to the combination treatment of ASTX727 and enasidenib in treating patients with higher-risk, IDH2-mutated myelodysplastic syndrome (MDS). ASTX727 is a combination of two drugs, decitabine and cedazuridine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have... Read More
