A Study Evaluating Efficacy of ABT-888 in Combination With Temozolomide in Metastatic Melanoma

A Randomized, Double-Blind, Placebo-Controlled, Phase 2 Study Evaluating the Efficacy of ABT-888 in Combination With Temozolomide Versus Temozolomide Alone in Subjects With Metastatic Melanoma

The purpose of this study is to evaluate the efficacy of ABT-888 in combination with temozolomide versus temozolomide alone in subjects with metastatic melanoma.

Inclusion Criteria:

• Histologically (or cytologically) confirmed metastatic melanoma.
• Unresectable Stage III or Stage IV metastatic melanoma.
• Measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) criteria.
• Subjects with no history of brain metastases demonstrated by a baseline MRI, or subjects with a history of previously treated brain metastases who have history of operable/SRS treatable brain metastases and completed surgical resection/stereotactic radiosurgery with or without adjuvant whole brain radiation at least 28 days prior to Day 1; have baseline MRI that shows no evidence of active intercranial disease; have discontinued taking medications for symptom management of brain metastases at least 7 days prior to Day 1
• 28 days since prior anti-cancer therapy.
• Eastern Cooperative Oncology Group (ECOG) Performance Score of 0-1.
• Adequate hematologic, renal and hepatic function.
• Partial Thromboplastin Time (PTT) is <= 1.5 x upper normal limit of institution's normal range and international normalized ratio (INR) < 1.5.
• Subject's with significant fluid retention may be allowed at the discretion of the investigator.
• Life expectancy > 12 weeks.
• Females must not be pregnant.
• Voluntarily signed informed consent.

Exclusion Criteria:

• Lactate Dehydrogenase (LDH) > 2 x Upper Limit of Normal (ULN).
• Ocular malignant melanoma.
• History of central nervous system metastases or leptomeningeal disease.
• Prior treatment with Dacarbazine (DTIC) or Temozolomide (TMZ).
• Prior DNA damaging agents or cytotoxic chemotherapy.
• Prior Whole Brain Radiation Therapy (with exceptions).
• Received an investigational agent within 28 days of study.
• History of seizure disorder and/or taking medication for seizure disorder.
• Active malignancy within the past 5 years, except cervical cancer in situ, in situ carcinoma of the bladder or non-melanoma carcinoma of the skin.
• Medical condition that would cause a high risk for toxicities.
