Procedure

Focused Ultrasound + Gemcitabine for Breast Cancer (Breast 54 Trial)

Phase 1
Recruiting
Research Sponsored by Patrick Dillon, MD
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion.
Patients must have a lesion in the breast/chest wall/axilla that is accessible to focused ultrasound ablation.
Must not have
Known history of HIV (Patients with HIV will be excluded because immunotherapy may impact the T cell profiling as part of the biologic correlates and the natural history of the disease)
Known active Hepatitis B virus or Hepatitis C virus
Timeline
Screening 3 weeks
Treatment Varies
Follow Up through month 7 (follow-up visit 2)
Awards & highlights
No Placebo-Only Group

Summary

This trial will test whether focused ultrasound ablation, low-dose gemcitabine, or a combination of the two can help early-stage breast cancer patients by affecting cells in the immune system. The hypothesis is that the combination of the two will be more effective and have fewer negative side effects than either treatment alone.

Who is the study for?
This trial is for adults with newly diagnosed breast cancer stages 1-3, regardless of hormone receptor status. Participants must have a lesion accessible to focused ultrasound and be willing to provide tissue samples. They should have good performance status (ECOG 0-2) and adequate organ function. Exclusions include those with breast implants on the treatment side, prior treatments for current cancer, pregnancy, certain steroid therapies or immunodeficiencies, known allergies to gemcitabine, other active cancers or infections.
What is being tested?
The study examines the safety and immune system effects of three regimens: focused ultrasound ablation alone, low-dose gemcitabine chemotherapy alone, and their combination in early-stage breast cancer patients. It aims to see if these treatments can reduce suppressor cells that hinder immunity while boosting T cell activity without compromising surgery outcomes.
What are the potential side effects?
Potential side effects may include typical reactions associated with chemotherapy like nausea, fatigue, lowered blood counts leading to increased infection risk; skin irritation from ultrasound; plus any unforeseen complications related to combining these two treatments.
