University of Chinese Academy Sciences

Status and phase: Unknown; Phase 2

Conditions: Metastatic Breast Cancer

Treatments: Drug: Physician's choice chemotherapy; Drug: Thalidomide

Study type: Interventional

Funder types: Other

Identifiers

NCT02649101

ZCHBC-007

Details and patient eligibility

About

Sixty advanced breast cancer patients are planed to enrolled in this clinical trial. Forty patients are enrolled into thalidomide plus chemotherapy group. Twenty patients are enrolled into chemotherapy alone group. There is no restriction on chemotherapy regimen and lines.

Full description

The study compares the combination of thalidomide and chemotherapy with chemotherapy alone for the treatment of stage IV breast cancer. Efficacy and safety of the chemotherapy-thalidomide combination will be evaluated. Assessing the isolated effects of thalidomide in a setting where pre and post treatment serum specimens can be obtained will provide essential information about the mechanisms by which vascular endothelial growth factor(VEGF) inhibition affects tumor growth, and represents an ideal opportunity to evaluate the molecular effects of thalidomide on breast tumor.

Enrollment: 60 estimated patients

Sex: Female

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
