Testing the Addition of Duvelisib or CC-486 to the Usual Treatment for Peripheral T-Cell Lymphoma
Recruiting
This phase II trial studies the effect of duvelisib or CC-486 and usual chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone in treating patients with peripheral T-cell lymphoma. Duvelisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as CC-486, cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone, work in different ways to stop the growth of cancer cells, either by... Read More

Additional Support Program Via Text Messaging and Telephone-Based Counseling for Breast Cancer Patients Receiving Hormonal Therapy
Recruiting
This phase III trial compares an additional support program (text message reminders and/or telephone-based counseling) with usual care in making sure breast cancer patients take their endocrine therapy medication as prescribed (medication adherence). Medication adherence is how well patients take the medication as prescribed by their doctors, and good medical adherence is when patients take medications correctly. Poor medication adherence has been shown to be a serious barrier to effective treat... Read More

Testing the Use of the Usual Chemotherapy Before and After Surgery for Removable Pancreatic Cancer
Recruiting
This phase III trial compares perioperative chemotherapy (given before and after surgery) versus adjuvant chemotherapy (given after surgery) for the treatment of pancreatic cancer that can be removed by surgery (removable/resectable). Chemotherapy drugs, such as fluorouracil, irinotecan, leucovorin, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before... Read More

Collection of Research Data and Samples From Patients Who Experience Immunotherapy Side Effects
Recruiting
This trial collects research data and samples from patients who experience immunotherapy side effects to store for use in future research studies. Studying research data and samples from patients who experience immunotherapy side effects may help researchers better understand how to predict, prevent, and treat these side effects.

Genetic Testing in Guiding Treatment for Patients With Brain Metastases
Recruiting
This phase II trial studies how well genetic testing works in guiding treatment for patients with solid tumors that have spread to the brain. Several genes have been found to be altered or mutated in brain metastases such as NTRK, ROS1, CDK, PI3K, or KRAS G12C. Medications that target these genes such as abemaciclib, paxalisib, entrectinib and adagrasib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Genetic testing may help doctors tailor treatment for... Read More
