Clinical Trials for Breast Cancer

HARMONY: Harnessing the Analysis of RNA Expression and Molecular Subtype to Optimize Novel TherapY for Metastatic Breast Cancer

Low burden on patient

The trial has a low burden on patients. An example would be a trial testing an oral drug, with scans every 12 weeks which would be similar to standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: Adults with metastatic breast cancer (up to one prior line of metastatic therapy) are eligible to have their tumor tissue analyzed using PAM50 RNA-based molecular subtyping, with results shared with their treating oncologist to inform and potentially change treatment planning; no investigational drugs are administered.

VIKTORIA-2: A Randomized, Open-Label, Phase 3 Study of Fulvestrant and CDK4/6 Inhibitors With or Without Gedatolisib as First-Line Treatment in Patients With HR-Positive and HER2-Negative Advanced Breast Cancer

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

TrialFetch AI summary: This trial enrolls adults with HR-positive, HER2-negative advanced or metastatic breast cancer whose disease progressed during or within 12 months of (neo)adjuvant endocrine therapy and who have not received prior systemic therapy for advanced disease; participants are randomized to receive standard fulvestrant plus a CDK4/6 inhibitor with or without gedatolisib, an investigational pan-PI3K/mTOR inhibitor that targets key resistance pathways.

ClinicalTrials.gov ID: NCT06757634

A Phase 2, Randomized, Active-controlled, Open-label, Multicenter Study of Belzutifan Plus Fulvestrant in Participants With Estrogen Receptor Positive, HER2 Negative Unresectable Locally Advanced or Metastic Breast Cancer After Progression on Previous Endocrine Therapy (LITESPARK-029)
