Gamma-Secretase/Notch Signalling Pathway Inhibitor RO4929097 and Temsirolimus in Treating Patients With Advanced Solid Tumors

This phase I trial is studying the side effects and best dose of giving gamma-secretase/Notch signalling pathway inhibitor RO4929097 and temsirolimus together in treating patients with advanced solid tumors. Gamma-secretase/Notch signalling pathway inhibitor RO4929097 and temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PRIMARY OBJECTIVES:

I. To determine the recommended phase II dose (RP2D) and safety profile of temsirolimus in combination with RO4929097 (gamma-secretase/Notch signalling pathway inhibitor RO4929097) in patients with advanced solid tumors.

SECONDARY OBJECTIVES:

I. To obtain pharmacokinetic (PK) profiles for both drugs when administered in combination in order to quantify the expected interactive effects in PK between these two agents.

II. To evaluate pharmacodynamic (PD) effects of both drugs when administered in combination, with the goal of identifying potential predictive and PD markers that need further exploration and validation in future trials.

OUTLINE: This is a multicenter, dose-escalation study.

Patients receive temsirolimus IV over 30 minutes on day -6 (course 1 only). Patients then receive temsirolimus IV or orally (PO) on days 1, 8, and 15 and gamma-secretase/Notch signalling pathway inhibitor RO4929097 PO once daily on days 1-3, 8-10, and 15-17. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Blood and tumor tissue samples may be collected periodically for pharmacokinetic and correlative analyses.

After completion of study treatment, patients are followed up for 4 weeks.
