Capecitabine for Breast Cancer
Trial Summary
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you are on antiestrogen treatments like aromatase inhibitors or selective estrogen modulators, you can continue them. Denosumab and zoledronic acid are also allowed as adjunct therapies.
What data supports the effectiveness of the drug Capecitabine (Xeloda) for breast cancer?
Is capecitabine (Xeloda) safe for humans?
How is the drug Capecitabine (Xeloda) unique in treating breast cancer?
Capecitabine (Xeloda) is unique because it is an oral medication that is selectively activated at the tumor site, producing the active drug 5-fluorouracil (5-FU) directly where it's needed. This drug is particularly beneficial for patients with metastatic breast cancer who have not responded to other treatments, and it is known for being well-tolerated with fewer side effects like hair loss and low blood cell counts.12359
What is the purpose of this trial?
This phase II trial evaluates the effect of capecitabine on tumor response using imaging and tumor markers to adjust dose (adaptive therapy) in patients with estrogen receptor (ER) positive, HER2 negative breast cancer that has spread from where it first started to other areas in the body (metastatic). Capecitabine is in a class of medications called antimetabolites. It is taken up by tumor cells and breaks down into fluorouracil, a substance that kills tumor cells. Adaptive therapy with capecitabine based on tumor burden response may slow or stop the growth of tumor cells in patients with metastatic ER positive, HER2 negative breast cancer.

Eligibility Criteria
This trial is for individuals with a type of breast cancer that responds to hormones (ER positive) and lacks the HER2 protein, which has spread beyond its original location. Participants must not have been treated with capecitabine before.Inclusion Criteria

Timeline
Screening
Participants are screened for eligibility to participate in the trial
Initial Standard Phase
Patients receive standard dose of capecitabine orally twice daily on days 1-14 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Adaptive Phase
Patients receive 50% reduced dose of capecitabine orally twice daily on days 1-14 of each cycle. Dose adjustments are made based on disease burden assessed via CT or blood samples. Cycles repeat every 21 days.
Follow-up
Participants are monitored for safety and effectiveness after treatment completion. Follow-up includes blood sample collection, CT or MRI, and bone scan if indicated.
