Changsha, HunanAges 18 years+ - NCT07708571Recruiting
Coaching program for women on ribociclib and aromatase inhibitor
This study tests whether a coaching program based on personality types helps women with early-stage hormone receptor-positive, HER2-negative breast cancer stick to their treatment plan. Participants must be taking ribociclib (Kisqali) and an aromatase inhibitor, and their cancer must not have spread to other organs.
Augsburg, BavariaAges 18 years+ - NCT04819243RecruitingPhase 2
Test a BRCA-targeted drug plan for advanced ER-positive breast cancer
This Phase 2 study tests how well a treatment plan using palbociclib followed by talazoparib (and possibly atezolizumab) works in certain people with advanced ER-positive breast cancer. It may help by targeting cancer biology linked to BRCA/HRD changes and by strengthening how the cancer is controlled.
Seoul, Gannam-guAges 19 years+ - NCT06832202RecruitingPhase 2
HLX22 plus Enhertu for HR+, HER2-low breast cancer
This trial tests a new drug, HLX22, combined with Enhertu (trastuzumab deruxtecan) for people with advanced breast cancer that is hormone receptor positive and HER2-low. The goal is to see if the combination works better than Enhertu alone.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07109726RecruitingPhase 1/Phase 2
Testing TER-2013 for advanced tumors with AKT/PI3K/PTEN changes
This trial tests a new drug called TER-2013, alone or combined with another drug (fulvestrant), for people with advanced solid tumors that have specific genetic changes in the AKT/PI3K/PTEN pathway. It aims to see if the drug is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT07661641RecruitingPhase 1
Study of new radioactive treatments for GRPR-positive tumors
This early-phase study tests two new radioactive treatments (lutetium-177 and actinium-225) together with a guided imaging agent in people with GRPR-positive solid tumors (including prostate, breast, or colorectal cancers). The goal is to see if these treatments can shrink tumors that have stopped responding to standard therapies.
