About

This Phase I clinical trial is studying the side effects and best dose of ABT-888 when given together with Temozolomide (chemotherapy) in treating patients with solid tumors, including metastatic melanoma (MM), BRCA deficient breast, ovarian, primary peritoneal, or fallopian tube cancer, and hepatocellular carcinoma (HCC).

Full description
