Gamma-Secretase Inhibitor RO4929097 and Cediranib Maleate in Treating Patients With Advanced Solid Tumors

PRIMARY OBJECTIVES:

I. To determine the tolerability, maximum tolerated dose (equivalent to the recommended phase II dose), and safety profile of RO4929097 (gamma-secretase inhibitor RO4929097) in combination with cediranib (cediranib maleate) in patients with advanced malignancies.

SECONDARY OBJECTIVES:

I. To obtain pharmacokinetic (PK) profiles for RO4929097 when administered alone and for RO492907 and cediranib in combination, in order to evaluate for interactive effects in PK (if any) between these two agents.

II. To evaluate pharmacodynamic (PD) effects of RO492907 when administered alone and in combination, with the goal of identifying potential predictive and PD markers that need further exploration and validation in future trials.

III. To assess for preliminary antitumor efficacy of this drug combination, especially in breast cancer, malignant melanoma, colorectal cancer, pancreatic cancer, kidney cancer, high grade glioma, non-small-cell lung cancer, and ovarian cancer.

OUTLINE: This is a dose-escalation study.

Patients receive gamma-secretase inhibitor RO4929097 orally (PO) once daily (QD) on days 1-3, 8-10, and 15-17 (days 1-3, 8-10, 15-17 22-24, 29-31, and 36-38 of course 1) and cediranib maleate PO QD on days 1-21 (days 22-42 course 1 only). Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

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