Sorafenib and Temsirolimus in Treating Patients With Metastatic, Recurrent, or Unresectable Melanoma

Study Overview
=================
Brief Summary
-----------------
This phase II portion of the trial is studying the side effects and best dose of temsirolimus when given together with sorafenib and to see how well they work in treating patients with metastatic, recurrent, or unresectable melanoma. Sorafenib and temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Sorafenib may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving sorafenib together with temsirolimus may kill more tumor cells.

Detailed Description
-----------------
PRIMARY OBJECTIVES: To evaluate the clinical activity, in terms of overall response rate (complete and partial response), of this regimen in these patients. (Phase II) To evaluate the in vivo biological activity of this regimen in these patients. SECONDARY OBJECTIVES: I. To determine the progression-free survival and overall survival of patients treated with this regimen. II. To determine the safety and toxicity of this regimen in these patients. III. To Determine the population pharmacokinetics of this regimen in these patients. IV. To correlate tumor and blood biomarkers with clinical outcome in patients treated with this regimen. OUTLINE: Upon completion of the multicenter, phase I, dose-escalation study followed to be followed by this phase II, open-label study. Patients receive temsirolimus IV over 30 minutes on days 1, 8, 15, and 22 and oral sorafenib once or twice daily on days 1-28. Treatment course repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed every 3-6 months.

Eastern Cooperative Oncology Group (ECOG) performance status 0-1. Bilirubin normal Creatinine normal or creatinine clearance ≥ 60 mL/min Not pregnant or nursing Negative pregnancy test Fertile patients must use effective contraception during and for 30 days after completion of study treatment. No history of allergic reactions attributed to compounds of similar chemical or biological composition to sorafenib or temsirolimus. No uncontrolled hypertension, defined as systolic blood pressure > 140 mm Hg on 2 separate days < 1 week prior to study entry OR diastolic pressure > 90 mm Hg on 2 separate days < 1 week prior to study entry. No evidence of bleeding diathesis or coagulopathy. No condition that would impair the ability to swallow pills (e.g., gastrointestinal tract disease resulting in an inability to take oral medication; requirement for IV alimentation; or active peptic ulcer disease). No uncontrolled illness including, but not limited to, any of the following: ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia or psychiatric illness or social situations that would limit study compliance. No traumatic injury within the past 3 weeks. No more than 1 prior systemic chemotherapy regimen for metastatic melanoma (Phase II). No prior sorafenib, temsirolimus, or any other agents targeting raf, vascular endothelial growth factor (VEGF)/VEGF receptor, or mTOR (Phase II). No prior surgical procedures affecting absorption. At least 3 weeks since prior major surgery. At least 4 weeks since prior chemotherapy (6 weeks for nitrosoureas or mitomycin C) for melanoma and recovered. At least 4 weeks since prior radiotherapy and recovered. Prior biologic or immunotherapeutic regimens allowed. Prior regional chemotherapy regimens (e.g., isolated limb perfusion) allowed but only 1 prior regional chemotherapy regimen allowed if all target lesions are within the prior regional treatment field. No concurrent enzyme-inducing antiepileptic drugs including, but not limited to, any of the following: phenytoin, carbamazepine, phenobarbital, rifampin or Hypericum perforatum (St. John's wort). No concurrent prophylactic hematopoietic colony-stimulating factors. No other concurrent investigational agents. No other concurrent anticancer agents or therapies for this cancer. No concurrent full-dose anticoagulation (i.e., warfarin, IV heparin, or low-molecular weight heparin). No concurrent grapefruit or grapefruit juice. No concurrent combination antiretroviral therapy for HIV-positive patients. Concurrent prophylactic anticoagulation therapy (e.g., low-dose warfarin) allowed provided prothrombin time (PT) international normalized ratio (INR) < 1.1 times upper limits of normal (ULN). Unidimensionally measurable disease >= 20 mm by conventional techniques or >= 10 mm by spiral computed tomography (CT) scan (longest diameter to be recorded) and margins of visible cutaneous metastatic lesions should be clearly defined and measured in at least one dimension as >= 10 mm. No known brain metastases unless the following criteria are met: no radiographical evidence of recurrences in the brain >= 3 months after complete resection of the brain metastases, asymptomatic brain metastases stable for >= 3 months since whole-brain radiation therapy and/or stereotactic radiosurgery and must not require steroid for brain metastases. White Blood Count (WBC) >= 3,000/mm³ Absolute neutrophil count >= 1,500/mm³ Platelet count >= 100,000/mm³ Serum cholesterol =< 350 mg/dL Triglycerides =< 400 mg/dL Alanine aminotransferase (ALT)/aspartate aminotransferase (AST) =< 2.5 times upper limit of normal. No peripheral neuropathy > grade 2. At least 5 years since prior chemotherapy for other types of cancer.
