Phase 2

Completed

• Conditions: Gastrointestinal Stromal Tumor; Recurrent Adult Soft Tissue Sarcoma; Stage I Adult Soft Tissue Sarcoma; Stage II Adult Soft Tissue Sarcoma; Stage III Adult Soft Tissue Sarcoma; Stage IV Adult Soft Tissue Sarcoma
• Interventions: Drug: temsirolimus; Other: laboratory biomarker analysis

• Registration Number: NCT00087074
• Lead Sponsor: National Cancer Institute (NCI)

Brief Summary

This phase II trial is studying how well CCI-779 works in treating patients with soft tissue sarcoma or gastrointestinal stromal tumor. Drugs used in chemotherapy, such as CCI-779, work in different ways to stop tumor cells from dividing so they stop growing or die.

Detailed Description

PRIMARY OBJECTIVES:

I. To assess the antitumor activity of CCI-779 in this patient population.

SECONDARY OBJECTIVES:

I. To assess the following in patients with soft tissue sarcomas and following treatment with CCI-779: duration of response, time to progression, survival.

TERTIARY OBJECTIVES:

I. To describe and correlate the following with patient characteristics and outcome in this patient population and following treatment with CCI-779: relative levels of 4EBP1 to eIF4E, phospho 4EBP1, total and phospho ribosomal S6 on pretreatment tumor tissue, expression levels of EGFR, activated EGFR, Her2, c-Myc, phospho Akt, total Akt, phospho-mTOR and total mTOR on pretreatment tumor tissue, drug induced inhibition of p70S6 kinase activity, and phosphorylation of S6 in PBMC, relative levels of serum sirolimus in post-treatment samples.

OUTLINE:

Patients receive CCI-779 IV over 30 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) receive 2 additional courses beyond CR.

Patients are followed every 3 months for 1 year, every 4 months for 1 year, and then every 6 months for 3 years.

Arm && Interventions

Group	Intervention	Description
Treatment (temsirolimus)	laboratory biomarker analysis	Patients receive CCI-779 IV over 30 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) receive 2 additional courses beyond CR.
Treatment (temsirolimus)	temsirolimus	Patients receive CCI-779 IV over 30 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) receive 2 additional courses beyond CR.

Primary Outcome Measures

Name	Time	Method
Proportion of confirmed tumor responses, defined to be either a CR or PR noted as the objective status on 2 consecutive evaluations at least 4 weeks apart	Up to 6 months (6 courses)

Secondary Outcome Measures

Name	Time	Method
Survival time	Time from registration to death due to any cause, assessed up to 5 years	The distribution of survival time will be estimated using the method of Kaplan-Meier.
Time to disease progression	Time from registration to documentation of disease progression, assessed up to 5 years	The distribution of time to progression will be estimated using the method of Kaplan-Meier.
Duration of response is defined for all evaluable patients who have achieved an objective response as the date at which the patient's objective status is first noted to be either a CR or PR to the date progression is documented	Up to 5 years
Time to treatment failure	Time from the date of randomization to the date at which the patient is removed from treatment due to progression, toxicity, or refusal, assessed up to 5 years
