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

This phase I 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 temosirolimus may kill more tumor cells.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose of temsirolimus when administered with sorafenib in patients with metastatic, recurrent, or unresectable melanoma.

II. To determine the safety and toxicity of this regimen in these patients.

SECONDARY OBJECTIVES:

I. To Determine the population pharmacokinetics of this regimen in these patients.

II. To correlate tumor and blood biomarkers with clinical outcome in patients treated with this regimen.

OUTLINE: This is a multicenter, phase I, dose-escalation study followed by a phase II, open-label study (2005-0215).

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.

Eligibility Criteria:
Criteria:

* Tumor must be accessible to biopsy unless appropriate tumor sample collection has occurred within the past 3 months and patient agrees to provide these samples for this study.
* 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.

* 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 PT INR \< 1.1 times ULN.
