ClinicalTrials.gov Identifier: NCT00417677
Recruitment Status :
(Decision was made not to attempt a lower dose)
This study is being conducted to determine the Maximum Tolerated Dose (MTD) and efficacy of the combined treatment of Temsirolimus and Sunitinib for the treatment of Advanced Kidney Cancer
Condition or disease
Renal Cell Carcinoma
Drug: Combination of Temsirolimus and Sunitinib
Phase 1Phase 2
A study to determine the safety, tolerability, and maximum tolerated dose (MTD) of the combination of temsirolimus and sunitinib in subjects with advanced Renal Cell Carcinoma (RCC) (dose escalation phase). Once the MTD is determined, this study will also evaluate the efficacy of this combination by determining progression free survivial (PFS) at 12 months in subjects with advanced RCC (expanded cohort phase).
Initially, an ascending dose design will be used in order to evaluate the tolerability and safety of the combination and to determine the MTD of this combination (dose escalation phase)
Once appropriate doses of each agent have been determined, an expanded cohort of 100 subjects with advanced RCC will be enrolled and treated at the MTD, to obtain further safety and efficacy information
Secondary Outcome Measures :
To examine additional efficacy endpoints including: Response rate (RR), Overall Survival (OS), & Progression Free Survival at 6 months and 24 months.
To determine the pharmacokinetic (PK) parameters of temsirolimus alone and temsirolimus and sunitinib in combination
PK samples will be collected from 20 subjects in the expanded cohort. Concentrations of temsirolimus, sirolimus, and sunitinib will be analyzed using a noncompartmental modeling approach.The PK parameters will include estimation of the peak concentr

Inclusion Criteria for Dose Escalation Phase
Histologically confirmed advanced RCC.
Up to 2 prior systemic regimens for RCC.
Subject must have at least 1 measurable lesion that can be accurately measured in at least 1 dimension with the longest diameter ³10 mm when measured by spiral computed CT (5-mm slice thickness contiguous) or ³20 mm when measured by conventional CT (10-mm slice thickness contiguous) (lesion must be ³ 2 times the size of the slice thickness per RECIST).
More criteria apply
Exclusion Criteria for Dose Escalation Phase
Subjects with known active central nervous system (CNS) malignancy (primary or metastatic).
Prior therapy with sirolimus, temsirolimus or sunitinib.
Subjects receiving known strong Cytochrome P450 (CYP)3A4 isoenzyme inhibitors and/or inducers. Subjects receiving other CYP3A4 isoenzyme inhibitors and/or inducers not classified as strong inhibitors or inducers are eligible, provided they have been on a stable regimen for at least 4 weeks before screening.
More criteria apply
Inclusion Criteria for Expanded Cohort Phase
Subjects with histologically confirmed advanced RCC regardless of nephrectomy status who have received no prior systemic therapies for their disease.
Subjects with histologically confirmed advanced RCC regardless of nephrectomy status who have a least 4 weeks since prior treatment with palliative radiation therapy, and/or surgery and resolution of all toxic effects of prior therapy to NCI CTCAE (version 3.0) grade £1.
Subjects must have at least 1 measurable lesion that can be accurately measured in at least 1 dimension with the longest diameter ³10 mm when measured by spiral CT (5-mm slice thickness contiguous) or ³20 mm when measured by conventional CT (10-mm slice thickness contiguous) (lesion must be ³2 times the size of the slice thickness per RECIST).
More Criteria apply
Exclusion Criteria for the Expanded Cohort Phase
Subjects with a history of a CNS malignancy or metastatic disease to the CNS and subjects with a known, active CNS malignancy (primary or metastatic).
Subjects receiving known strong CYP3A4 isoenzyme inhibitors and/or inducers. Subjects taking other CYP3A4 isoenzyme inhibitors and/or inducers not classified as strong inhibitors or inducers are eligible, provided they have been on a stable regimen for at least 4 weeks before screening.
