Brief summary

This is a Phase 1, open-label, single centered trial to evaluate the mass balance, bioavailability and metabolism of pimasertib in cancer subjects with locally advanced or metastatic solid tumors.

Interventions

Part A: Subjects will receive unlabeled pimasertib capsules orally at a single dose of 60 milligram (mg) on Day 1. One hour after administration of the oral unlabeled pimasertib dose, the intravenous (IV) tracer dose of 9 kilobecquerel (kBq) \[14C\] pimasertib will be administered as a bolus injection. On Days 3-21 (except Day 8), subjects will receive unlabeled pimasertib capsules orally at a dose of 60 mg twice daily (BID). In the morning of Day 8, subjects will receive 60 mg unlabeled pimasertib capsules spiked with a dose of 2.6 megabecquerel (MBq) (70 microcuries \[mcgCi\]) of \[14C\] pimasertib orally. In the evening of Day 8, subjects will receive the evening dose of 60 mg pimasertib as unlabeled pimasertib capsules orally. Part B : Subjects will be administered with 60 mg BID unlabeled pimasertib as oral capsules continuously in cycles of 21 days until progression of the disease, unacceptable toxicity, withdrawal of consent by the subject, loss to follow-up or death.

Total Body Clearance of Total [14C] Radioactivity From Plasma Following Oral Administration (CL/f)

Clearance of a drug was a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. CL/f was influenced by the fraction absorbed. Apparent body clearance of total radioactivity from plasma was calculated by dividing the dose with area under the plasma concentration time curve from zero to infinity (Dose/AUC0inf).

Time frame: Pre dose, 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0, 8.0, 10.0, 12.0, 24.0, 48.0, 72.0, 96.0 and 168.0 hours post [14C]-labeled pimasertib dose on Day 8

Population: The Part A analysis set consists of all subjects who received the Part A medication, had absence of clinical trial protocol deviations affecting mass balance assessments, complied with trial medication with IMP intake for the complete Part A.

Total Body Clearance of Unlabeled Pimasertib (CL/f) and Intravenous [14C] Pimasertib (CL)

The total body clearance of drug from plasma following oral administration (Cl/f) and the total body clearance of drug from plasma following intravenous administration was calculated by dividing the Dose with area under the plasma concentration time curve from time zero to infinity (AUC0 inf)=Dose/AUC0- inf.

Time frame: Pre-dose, 0.5, 0.75, 1, 1.5, 2, 2.5, 4, 6, 8, 10, 12, 16, 24, and 48 hours post unlabeled pimasertib dose on Day 1; Pre-dose, 0.5, 1, 1.5, 3, 5, 7, 9, 11, 15, 23, and 47 hours post intravenous [14C] labeled pimasertib dose on Day 1

Population: The Part A analysis set consists of all subjects who received the Part A medication, had absence of clinical trial protocol deviations affecting mass balance assessments, complied with trial medication with IMP intake for the complete Part A.
