Chemotherapy Combined With Immunotherapy Versus Immunotherapy Alone for Older Adults With Stage IIIB-IV Lung Cancer, The ACHIEVE Trial
NCT06096844
Recruiting
This phase III trial compares the effect of adding chemotherapy to immunotherapy (pembrolizumab) versus immunotherapy alone in treating patients with stage IIIB-IV lung cancer. 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 work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividin... Read More

Studying the Safety and Determining the Optimal Dose of Novobiocin in Patients With Tumors That Have Alterations in DNA Repair Genes
NCT05687110
Recruiting
This phase I trial tests the safety, side effects, and best dose of novobiocin in treating cancer patients with alterations in deoxyribonucleic acid (DNA) repair genes. Novobiocin is an antibiotic that blocks the activity of a protein called DNA polymerase theta, which helps repair DNA that has become damaged as cells grow and divide. Cancer cells that cannot repair their damaged DNA die. This medication may help shrink or stabilize cancer with a mutation in DNA repair genes.

Optimizing HBV Care Cascade Among Foreign-Born in the United States (FOCUS-HBV Study)
NCT05621304
Recruiting
Background: People who were born outside of the country are the largest group of adults infected with chronic hepatitis B virus (HBV) in the US. HBV affects the liver. If not treated, HBV infection can lead to serious liver disease, including cancer. One recent study showed that only 35% of foreign-born US adults were aware of their HBV infections. Foreign-born US adults may also have trouble getting proper care after they are diagnosed with HBV. In one small survey, language, cultural, and fin... Read More

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...
NCT05621291
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

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.
