Sequential High-Dose Chemotherapy and Stem Cell Transplantation in Treating Patients With Chemotherapy-Sensitive Metastatic Breast Cancer
A Phase 2 study testing filgrastim, cyclophosphamide and megestrol acetate in people with Breast Cancer, run by Yale University at 1 site in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may kill more tumor cells. Read more about this study

About this study
Official title: Phase II Trial of Sequential High-Dose Alkylating Agents in Metastatic Breast Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may kill more tumor cells.
PURPOSE: Phase II trial to study the effectiveness of sequential high-dose chemotherapy followed by peripheral stem cell transplantation in treating patients with metastatic breast cancer that is responding to chemotherapy.
Read the detailed description
OBJECTIVES: I. Determine the feasibility and efficacy of sequential high-dose cyclophosphamide, melphalan, and thiotepa plus autologous peripheral blood stem cell rescue in patients with metastatic breast cancer with ongoing objective response to prior induction chemotherapy.
OUTLINE: Patients receive sequential therapy beginning with regimen A. Regimen A: Patients receive cyclophosphamide IV over 1 hour every 6 hours or more for 4 doses within 36 hours. Patients receive filgrastim (G-CSF) subcutaneously (SC) daily beginning 2 days after completion of cyclophosphamide and continuing until autologous peripheral blood stem cells (PBSC) are harvested. Regimen B: Beginning at least 3 weeks after initiation of regimen A, patients receive melphalan IV on days 1 and 2. Beginning on day 4, a portion of the PBSC are reinfused. Patients receive G-CSF SC daily beginning on day 4 and continuing until at least day 10. Regimen C: Beginning at least 3 weeks after initiation of regimen B, patients receive thiotepa IV over 2 hours on days 1 and 2. Beginning on day 5, the remaining PBSC are reinfused. Patients receive G-CSF SC daily beginning on day 5 and continuing until blood counts recover. During regimens A, B, and C, G-CSF must be discontinued at least 2 days before administration of any chemotherapy. Regimen D: After recovery from chemotherapy, patients with hormone receptor-positive tumors and no prior refractoriness to hormonal therapies receive oral tamoxifen daily, while patients with prior failure on tamoxifen receive oral megestrol 4 times daily. Patients undergo irradiation to sites of prior cutaneous, nodal, bone, or soft tissue bulk disease and resection of residual lesions. Patients are followed weekly for 1 month, biweekly for 2 months, monthly for 5 months, and then bimonthly for 1 year.
PROJECTED ACCRUAL: A minimum of 30 patients will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing filgrastim, cyclophosphamide and megestrol acetate in people with Breast Cancer, run by Yale University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2013; AzTrials last refreshed its copy on 1 Nov 2026.
