Evaluation of Drug Resistance in Patients With Metastatic Breast Cancer

• Status: Unknown status
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Some patients may develop a resistance to chemotherapy drugs.

PURPOSE: Phase II trial to determine the reliability of a test for measuring drug resistance to paclitaxel in patients with metastatic breast cancer.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Oncotech
• Treatments: Albumin-Bound Paclitaxel; Antineoplastic Agents; Paclitaxel
