This Phase 2 trial tests whether adding decitabine to one of three targeted medicines (ruxolitinib, fedratinib, or pacritinib) can improve outcomes in people with advanced myeloproliferative neoplasms that are progressing to a blast phase. It may help control the disease by combining blood-cancer chemotherapy with drugs that block disease-driving signaling.
Seattle, WashingtonAges 18 years+ - NCT04293562RecruitingPhase 3
Testing targeted drugs plus chemo for newly diagnosed AML
This study compares standard chemotherapy to chemotherapy plus CPX-351 and/or gilteritinib in children and young adults newly diagnosed with AML. It aims to see whether adding these targeted treatments improves outcomes, especially for certain gene changes like FLT3.
Birmingham, AlabamaAges Up to 21 years - NCT04305691RecruitingPhase 2
Ixazomib for skin Kaposi sarcoma in people with HIV
This trial studies ixazomib (a targeted anti-cancer medicine) to treat cutaneous (skin) Kaposi sarcoma. It aims to shrink measurable skin lesions and improve symptoms, especially in people living with HIV.
San Diego, CaliforniaAges 18 years+ - NCT04304846Recruiting
Follow-up program for very preterm babies at age 3
This trial is part of a regional follow-up program for babies born very early. It looks at how these “extremely preterm” children do as they grow, and can help the care team spot needs earlier at the age-3 visit.
AngersAges 3–6 - NCT04305834RecruitingPhase 2
Abemaciclib plus hormone pills for metastatic breast cancer in older adults
This Phase 2 study tests whether abemaciclib combined with standard hormone (endocrine) therapy can better control metastatic breast cancer in people age 70 and older. It may help if your cancer has already grown despite prior hormone therapy and/or other cancer medicines.
Duarte, CaliforniaAges 70 years+ - NCT04329494RecruitingPhase 1
Study of targeted drug delivery into the abdomen using PIPAC
This Phase 1 trial tests PIPAC, a way to deliver anti-cancer medicine directly into the abdomen using a minimally invasive procedure. It is for people with peritoneal spread from certain cancers to see whether this approach is safe and potentially helpful.
Duarte, CaliforniaAges 18 years+ - NCT04334031Recruiting
Hospital follow-up study for immune-related disease
