Adding an Immunotherapy Drug, MEDI4736 (Durvalumab), to the Usual Chemotherapy Treatment (Paclitaxel, Cyclophosphamide, and Doxorubicin) for Stage II-III Breast Cancer
NCT06058377
Recruiting
This phase III trial compares the addition of an immunotherapy drug (durvalumab) to usual chemotherapy versus usual chemotherapy alone in treating patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, 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 paclitaxel, doxorubicin, and... Read More

FORAGER-1: A Study of LOXO-435 (LY3866288) in Participants With Cancer With a Change in a Gene Called FGFR3
NCT05614739
Recruiting
The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435 by itself or when it is combined with other standard medicines that treat cancer. LOXO-435 may be used to treat cancer of the cells that line the urinary system and other solid tumor cancers that have a change in a particular gene (known as the FGFR3 gene). Participation could last up to 30 months (2.5 years) and possibly longer if the disease does not get worse.

NCT05564390
Recruiting
This MyeloMATCH Master Screening and Reassessment Protocol (MSRP) evaluates the use of a screening tool and specific laboratory tests to help improve participants' ability to register to clinical trials throughout the course of their myeloid cancer (acute myeloid leukemia or myelodysplastic syndrome) treatment. This study involves testing patients' bone marrow and blood for certain biomarkers. A biomarker (sometimes called a marker) is any molecule in the body that can be measured. Doctors look... Read More

This ComboMATCH patient screening trial is the gateway to a coordinated set of clinical trials to study cancer treatment directed by genetic testing. Patients with solid tumors that have spread to nearby tissue or lymph nodes (locally advanced) or have spread to other places in the body (advanced) and have progressed on at least one line of standard systemic therapy or have no standard treatment that has been shown to prolong overall survival may be candidates for these trials. Genetic tests loo... Read More

Comparing Cytarabine + Daunorubicin Therapy Versus Cytarabine + Daunorubicin + Venetoclax Versus Venetoclax + Azacitidine in Younger Patients With Intermediate Risk AML (A MyeloMATCH Treatment Trial)
NCT05554393
Recruiting
This phase II MyeloMATCH treatment trial compares cytarabine with daunorubicin versus cytarabine with daunorubicin and venetoclax versus venetoclax with azacitidine for the treatment of younger patients with intermediate risk acute myeloid leukemia (AML). Cytarabine is a drug that inhibits some of the enzymes needed for deoxyribonucleic acid (DNA) replication and repair and can slow or stop the growth of cancer cells. Daunorubicin is a drug that blocks a certain enzyme needed for cell division a... Read More
