Drug Resistance Inhibition in Treating Women With Recurrent or Metastatic Breast Cancer
A Phase 2 study testing paclitaxel and valspodar in people with Breast Cancer, run by Eastern Cooperative Oncology Group at 9 sites in United States.
Trial summary
RATIONALE: Some tumors become resistant to chemotherapy drugs. Combining PSC 833 with a chemotherapy drug may reduce resistance to the drug, and allow the tumor cells to be killed. Read more about this study

About this study
Official title: A PILOT PHASE II TRIAL OF PSC 833 MODULATION OF MULTIDRUG RESISTANCE TO PACLITAXEL IN THE TREATMENT OF METASTATIC CARCINOMA OF THE BREAST
RATIONALE: Some tumors become resistant to chemotherapy drugs. Combining PSC 833 with a chemotherapy drug may reduce resistance to the drug, and allow the tumor cells to be killed.
PURPOSE: Phase II trial to study the effectiveness of PSC 883 and paclitaxel in treating women who have recurrent or metastatic breast cancer.
Read the detailed description
OBJECTIVES: I. Evaluate the antitumor activity, as measured by frequency of objective response and time to progression, of the multidrug resistance modulator PSC 833 in combination with paclitaxel in women with recurrent or metastatic breast cancer. II. Describe the toxicity of this regimen.
OUTLINE: All patients receive PSC 833 by mouth every 6 hours for a total of 12 doses. Paclitaxel is infused over 3 hours, after the 5th dose of PSC 833. Treatment is repeated every 3 weeks in stable and responding patients. PSC 833 must not be mixed with grapefruit juice. Growth factors may be used at the discretion of the investigator. Patients are followed every 3 months for the first two years, then every 6 months for years 2-5, and then annually thereafter.
PROJECTED ACCRUAL: It is anticipated that approximately 36 patients will be entered over 24 months if there are at least 6 responses in the first 17 patients.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing paclitaxel and valspodar in people with Breast Cancer, run by Eastern Cooperative Oncology Group at 9 sites 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 7 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites 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?
On the ClinicalTrials.gov record for NCT00002826, which also lists 1 linked publication.
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 7 Jun 2023.
