Registration Number
NCT04672460
Lead Sponsor
Pfizer
Brief Summary

This will be a Phase 1, open label, 2-sequence, crossover study to establish the BE of the current commercial formulation (Generation 3.1 talazoparib capsules) to the proposed talazoparib liquid-filled soft gelatin capsule (soft gel capsule) formulation after multiple dosing under fasting conditions in participants with advanced solid tumors. In addition, the effect of food on the PK of the proposed talazoparib soft gel capsule formulation will be evaluated in fixed sequence after the 2 BE assessment periods.

Primary Outcome Measures
NameTimeMethod
Area Under the Plasma Concentration-Time Profile From Time 0 to 24 Hours (AUC24) of Talazoparib After Multiple Dosing Under Fasted ConditionsSerial blood sample (4 mL) each was collected at predose on Day 27 of Period 1 and Day 20 of Periods 2 and predose and 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, and 24 hours postdose on Day 28 of Period 1 and Day 21 of Period 2 to 3, respectively.

AUC24 was defined as area under the plasma concentration-time profile from time zero to 24 hours post dose. The geometric coefficient of variation is expressed in percentage. The ratio (Test/Reference) of adjusted means and 90% CI were expressed as percentages.

Maximum Observed Plasma Concentration (Cmax) of Talazoparib After Multiple Dosing Under Fasted ConditionsSerial blood sample (4 mL) each was collected at predose on Day 27 of Period 1 and Day 20 of Periods 2 and predose and 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, and 24 hours postdose on Day 28 of Period 1 and Day 21 of Period 2 to 3, respectively.

Cmax was the maximum observed plasma concentration and was directly observed from data. The geometric coefficient of variation was expressed in percentage. The ratio (Test/Reference) of adjusted means and 90% CI were expressed as percentages.

Area Under the Plasma Concentration-Time Profile From Time 0 to 24 Hours (AUC24) of Talazoparib After Multiple Dosing Under Fed ConditionsSerial blood sample (4 mL) each was collected at predose on Day 27 of Period 1 and Day 20 of Periods 2 and predose and 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, and 24 hours postdose on Day 28 of Period 1 and Day 21 of Period 2 to 3, respectively.

AUC24 was defined as area under the plasma concentration-time profile from time zero to 24 hours post dose. The geometric coefficient of variation is expressed in percentage. The ratio (Test/Reference) of adjusted means and 90% CI were expressed as percentages.

Maximum Observed Plasma Concentration (Cmax) of Talazoparib After Multiple Dosing Under Fed ConditionsSerial blood sample (4 mL) each was collected at predose on Day 27 of Period 1 and Day 20 of Periods 2 and predose and 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, and 24 hours postdose on Day 28 of Period 1 and Day 21 of Period 2 to 3, respectively.

Cmax was the maximum observed plasma concentration and was directly observed from data. The geometric coefficient of variation was expressed in percentage. The ratio (Test/Reference) of adjusted means and 90% CI were expressed as percentages.

Secondary Outcome Measures
NameTimeMethod
Apparent Clearance After Oral Dose (CL/F) of Talazoparib After Multiple DosingSerial blood sample (4 mL) each was collected at predose on Day 27 of Period 1 and Day 20 of Periods 2 and predose and 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, and 24 hours postdose on Day 28 of Period 1 and Day 21 of Period 2 to 3, respectively.

Apparent Clearance After Oral Dose (CL/F) was defined as apparent clearance after oral dose on the last day of treatment period. The geometric coefficient of variation is expressed in percentage.

Time of Observed Maximum Plasma Concentration (Tmax) of Talazoparib After Multiple DosingSerial blood sample (4 mL) each was collected at predose on Day 27 of Period 1 and Day 20 of Periods 2 and predose and 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, and 24 hours postdose on Day 28 of Period 1 and Day 21 of Period 2 to 3, respectively.

Tmax was defined as time to reach maximum observed plasma concentration.

Area Under the Plasma Concentration-Time Profile From Time 0 to Time of the Last Quantifiable Concentration (AUClast) of Talazoparib After Multiple DosingSerial blood sample (4 mL) each was collected at predose on Day 27 of Period 1 and Day 20 of Periods 2 and predose and 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, and 24 hours postdose on Day 28 of Period 1 and Day 21 of Period 2 to 3, respectively.

AUClast was area under the plasma concentration time-curve from zero (pre-dose) to the last measured concentration. The geometric coefficient of variation was expressed in percentage.

Predose Concentration During Multiple Dosing (Ctrough) of Talazoparib After Multiple DosingSerial blood sample (4 mL) each was collected at predose on Day 27 of Period 1 and Day 20 of Periods 2, predose and 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, and 24 hours postdose on Day 28 of Period 1 and Day 21 of Period 2 to 3, respectively.

Ctrough was the pre-dose concentration during multiple dosing and was directly observed from data. The geometric coefficient of variation is expressed in percentage.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) (All Causalities)Day 1 up to 28 days after last dose of study drug (maximum up to 388 days)

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Grade 3: severe or medically significant but not immediately life-threatening, hospitalization or prolongation of existing hospitalization indicated, disabling, limiting self-care ADL; Grade 4: life-threatening consequence, urgent intervention indicated; Grade 5: death related to AE. Treatment-emergent adverse event (TEAE) means event between first dose of study treatment and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. An SAE was an AE resulting in any of death; inpatient hospitalization; life-threatening experience; disability; congenital anomaly or deemed significant for any other reason.
