Medical Responsible

This is a Phase 1, multi-center, open-label, single-dose, 2 period, 2 sequence cross-over trial to investigate the relative bioavailability of 2 solid oral pimasertib formulations in cancer subjects (Part A), followed by open-label pimasertib administration (Part B and trial extension phase).

Relative Bioavailability of Pimasertib in Cancer Patients

A Multi-Center, Open-Label, Single 60 mg Dose, Two Period, Two Sequence Cross-Over Trial to Investigate the Relative Bioavailability of Two Solid Oral Pimasertib Formulations in Cancer Patients

Maximum observed plasma concentration (Cmax) was calculated for Part A Pimasertib 60 mg Capsule and tablet.

Area under the plasma concentration-time curve from time zero to the last sampling time (AUC0-t) at which the concentration was at or above the lower limit of quantification.

Clearance of a drug was a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Volume of distribution was defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

An AE was any untoward medical occurrence in a subject who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug administration until 30 days after the last dose of study drug administration that were absent before treatment or that worsened relative to pre treatment state.

CR as per Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 defined as disappearance of all target lesions except lymph nodes (LN); LN must have a decrease in the short axis to less than (\<)10 millimeter (mm).

PR as per RECIST v1.1 defined as 30% decrease in sum of diameters of target lesions taking as reference the baseline sum diameters.

SD as per RECIST v1.1 defined as neither shrinkage to qualify for PR nor increase to qualify for progressive disease (PD) taking the smallest sum diameters on study as reference. PR = 30% decrease in sum of diameters of target lesions taking as reference the baseline sum diameters; PD = 20% increase in sum of diameters of target lesions; the appearance of \>=1 new lesions.

PD as per RECIST v1.1 defined as 20% increase in sum of diameters of target lesions; the appearance of \>=1 new lesions.
