A Phase 1, Single Dose, Randomized, Cross-over Absolute Bioavailability Study in Healthy Subjects Comparing Oral to Intravenous Administration of GDC-0973

The primary objective of Part 1 of this study is to evaluate the safety and tolerability of the intravenous (IV) dose of GDC-0973. The primary objectives of Part 2 of this study are to evaluate the absolute bioavailability of GDC-0973 and to evaluate the pharmacokinetic (PK) of GDC-0973 following IV and oral administration. The secondary objective of Part 2 of this study is to evaluate the safety of GDC-0973 administered orally and intravenously.

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population PK modelling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Absolute Oral Bioavailability (F) of GDC-0973
Prazo: Part 2: 0 Hrs (pre-dose), 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 144, and 192 Hrs post-dose on Day 1
Absolute oral bioavailability is the amount of drug from a formulation that reaches the systemic circulation relative to an IV dose. F = [AUC (0-∞), oral multiplied by Dose IV] divided by [AUC (0-∞), IV multiplied by Dose oral]. Absolute oral bioavailability is determined for drugs which are administered orally. IV dose is 100% in systemic circulation (dosed directly) and hence no estimation is required.
Part 2: 0 Hrs (pre-dose), 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 144, and 192 Hrs post-dose on Day 1

MAT is mean time required for the drug to reach the central compartment. MAT was estimated from the mean resident time (MRT) from oral and IV administration. MAT was calculated as MRT last of oral dose minus MRT last of IV dose. MAT is analyzed when drug is administered orally (only for non-IV routes of administration).
Part 2: 0 Hrs (pre-dose), 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 144, and 192 Hrs post-dose on Day 1

Prazo: Part 2: 0 to 12, 12 to 24, 24 to 48, 48 to 72, and 72 to 96 Hrs post-dose on Day 1
The cumulative amount of drug excreted in urine over the entire collection interval of 96 hrs was calculated by adding the Aeu of the intervals 0 to 12, 12 to 24, 24 to 48, 48 to 72, and 72 to 96 hrs where Aeu was calculated by multiplying the urine volume within the collection interval by the associated drug concentration.
Part 2: 0 to 12, 12 to 24, 24 to 48, 48 to 72, and 72 to 96 Hrs post-dose on Day 1
Renal Clearance (CLR) of IV and Oral GDC-0973
Prazo: Part 2: 0 Hrs (pre-dose), 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 144, and 192 Hrs post-dose on Day 1 for plasma; 0 to 12, 12 to 24, 24 to 48, 48 to 72, and 72 to 96 Hrs post-dose for urine
CLR was calculated as Aeu divided by AUC (0 - ∞), where Aeu was amount of drug excreted in urine from time 0 to 96 hrs post-dose and AUC(0 - ∞) was area under the concentration-time curve of the analyte in plasma over the time interval from zero extrapolated to infinity hrs post-dose.
Part 2: 0 Hrs (pre-dose), 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 144, and 192 Hrs post-dose on Day 1 for plasma; 0 to 12, 12 to 24, 24 to 48, 48 to 72, and 72 to 96 Hrs post-dose for urine
Percent of GDC-0973 Excreted in the Urine (% Excreted) for IV and Oral GDC-0973
Prazo: Part 2: 0 to 12, 12 to 24, 24 to 48, 48 to 72, and 72 to 96 Hrs post-dose
% Excreted is the mean percentage of dose recovery in urine and calculated as: (Aeu divided by dose) multiplied by 100, where Aeu was amount of drug excreted in urine from time 0 to 96 hrs post-dose.
Part 2: 0 to 12, 12 to 24, 24 to 48, 48 to 72, and 72 to 96 Hrs post-dose
