Clinical Trial Summary

In the past 5 years, treatment for metastatic Renal Cell Carcinoma (mRCC) has focused on agents directed at blocking tumor and vascular growth pathways. Sunitinib blocks the vascular endothelial growth factor receptor (VEGFr) and temsirolimus is an inhibitor of mammalian target of rapamycin (mTOR). Both sunitinib and temsirolimus are FDA approved agents for mRCC. When agents like these are given together, the toxicity increases but they can be given safely, at full doses, sequentially. We hypothesize that alternating these agents will double the progression free survival (PFS) of the agents when given sequentially.

Description:

SUMMARY: Alternating Targeted Therapy in Patients with Metastatic Renal Cell Carcinoma: A Phase II Study of Alternating Sunitinib and Temsirolimus Patients with measurable metastatic renal cell carcinoma (any histology) are eligible. All patients will be treated as outlined below with sunitinib alternating with temsirolimus. Patients will be treated continuously, until evidence of progression of disease, or for up to two cycles following disappearance of all disease. A cycle is defined as: Sunitinib 50mg by mouth daily for 4 weeks followed by a two week rest Temsirolimus 25mg IV weekly for 4 weeks followed by a two week rest

• In patients with a prior history of invasive malignancy, less than five years in complete remission.
• Have evidence of significant co-morbid illness such as uncontrolled diabetes, hypertension or active infection that would preclude treatment on this regimen.

• Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels
• Any serious and/or unstable pre-existing medical, psychiatric, or other conditions that could interfere with subject's safety, obtaining informed consent or compliance to the study.
• Is now undergoing and/or has undergone in the 14 days immediately prior to first dose of study drug any minor surgeries (i.e. skin biopsy, tooth extraction, etc.) and recovered from all ill effects.
• Any ongoing toxicity from prior anti-cancer therapy that is >Grade 1 and/or that is progressing in severity.
• Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to sunitinib or temsirolimus.
• Untreated brain metastasis. (Brain metastases that are stable based on radiographic evidence 4 weeks after radiation and/or surgery are permitted).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression Free Survival	To determine the time to disease progression in metastatic renal cell carcinoma patients treated with alternating targeted therapy. This time interval constitutes the metric progression free survival time.	From the date of randomization until the first documented disease progression or date of death from any cause, evaluated every 12 weeks throughout duration of study treatment
Secondary	Clinical Response Rate as Measured by Best Response Achieved	To be assigned a status of partial response or complete response, changes in tumor measurements must be confirmed by repeat assessments that should be performed no less than 4 weeks after the criteria for response are first met. In the case of stable disease, follow-up measurements must have met the stable disease criteria at least once after study entry at a minimum interval (in general, not less than 6-8 weeks) that is defined in the study protocol. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT/MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR	Every 12 weeks from randomization until progression, estimated time frame is 18 months
Secondary	To Characterize the Toxicity Profile	The toxicity profile will be characterized by observations of AEs and SAEs graded by the CTCAE criteria v4.0.	Throughout the duration of the patient remaining on study treatment which was a median time of 8 months
