Temsirolimus in Treating Patients With Locally Advanced or Metastatic Cervical Cancer That Cannot Be Removed By Surgery

Official Title: “A Phase II Study of Temsirolimus (NSC 683864), an mTOR Inhibitor, in Patients With Recurrent, Unresectable, Locally Advanced or Metastatic Carcinoma of the Cervix”

RATIONALE: Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase II trial is studying how well temsirolimus works in treating patients with locally advanced or metastatic cervical cancer that cannot be removed by surgery.

OBJECTIVES: - To assess the efficacy of temsirolimus, in terms of objective response rate, in patients with unresectable, locally advanced or metastatic carcinoma of the cervix. - To assess the time to progression and response duration in patients treated with this drug. - To assess the adverse events associated with this drug in these patients. - To explore the relationship between expression of proteins in the mTOR pathway in archival tissue samples and objective response to therapy.

OUTLINE: This is a multicenter study.

Patients receive temsirolimus IV over 30 minutes on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Patients undergo tumor tissue sample collection for laboratory biomarker studies, including analysis of PTEN expression by IHC, PTEN promoter methylation, and PTEN genomic losses and PIK3CA copy number by FISH.

After completion of study therapy, patients are followed up at 4 weeks and then every 3 months thereafter until relapse/progression.

PRIOR CONCURRENT THERAPY:

• No prior treatment with an mTOR inhibitor
• No more than one prior chemotherapy regimen
• Radiosensitizing cisplatin given concurrently with radiotherapy at the time of initial diagnosis and treatment is not considered systemic chemotherapy

• At least 28 days since prior radiotherapy (except for low-dose, palliative radiotherapy) and recovered
• At least 28 days since prior major surgery (wound healing must have occurred)
• No other concurrent investigational agents or anticancer therapy
• Concurrent therapeutic anticoagulation allowed provided PT/INR or PTT is closely monitored during study therapy
