A Study of Dalotuzumab + MK-2206, Dalotuzumab + MK-0752, and Dalotuzumab + Ridaforolimus Combination Therapies in Participants With Advanced Cancer (MK-0646-027)

This is an open-label, two-part study to evaluate the safety and tolerability of combination treatment with dalotuzumab + MK-2206, dalotuzumab + MK-0752, or dalotuzumab + ridaforolimus (MK-8669). Part 1 of the study will determine the dose-limiting toxicities (DLTs) observed after administration of each of the combinations at various doses and define the maximum tolerated dose (MTD) of each combination. Part 2 of the study will assess preliminary anti-tumor activity of these combinations (at MTD) in two groups of participants with selected tumor biomarkers: one group with metastatic or recurrent platinum-resistant ovarian cancer, fallopian tube cancer, or primary peritoneal cancer and one group with metastatic or recurrent colorectal cancer. The dalotuzumab + ridaforolimus and dalotuzumab + MK-2206 arms will be enriched with female platinum-resistant ovarian cancer, fallopian tube cancer, or primary peritoneal cancer participants. The dalotuzumab + MK-0752 arm will be enriched with metastatic or recurrent wild-type kirsten rat sarcoma (KRAS) colorectal cancer participants. The primary hypothesis is that the DLTs observed in adult patients with locally advanced or metastatic solid tumors after administration of each of the MK-MK doublets will be dose-dependent to allow for definition of a MTD within each MK-MK doublet.
