Group Intervention Description Treatment C AZD2281 400mg bid (twice daily) tablet dose Treatment B AZD2281 400 mg twice daily (bid) capsule dose Treatment A AZD2281 300mg bid (twice daily) tablet dose
- Primary Outcome Measures
Name Time Method Dose Escalation Phase of continued supply expansion: To determine safety & tolerability of higher than 200mg bid (to 400mg) of tablet & compare safety & tolerability profile of tablet with 400mg capsule at every visit PK Phase Primary Outcome: To determine the comparative bioavailability of a new tablet formulation of AZD2281 compared to the existing capsule formulation Blood samples (12) will be taken at pre-defined intervals following dosing of a single capsule and a single tablet dose Continued Supply Expansion Phase: To compare the safety and tolerability of the tablet and capsule formulation of AZD2281 in all patients: Safety, AEs, Physical Exam, vital signs at every visit Randomised tablet formulation continued supply expansion phase (Group 8): To determine the safety and tolerability profile of selected tablet dose schedules of the melt-extrusion (tablet) formulation. at every visit Continued Supply Phase: To enable patients to continue to receive treatment with AZD2281. Safety and tolerability data will be collected to further determine the safety and tolerability of the capsule formulation of AZD2281 in these patients every 28 days
- Secondary Outcome Measures
Name Time Method To compare the extent of PARP inhibition achieved in peripheral blood mononuclear cells (PBMCs) following dosing of both the new tablet formulation and existing capsule formulation Blood samples (4) will be taken at pre-defined intervals prior to and following dosing of a single capsule and a single tablet dose Dose Escalation Phase of the continued supply expansion: To compare between patients the single dose and steady state exposures of AZD2281 achieved with selected tablet doses and the 400mg bid capsule dose at every visit PK Phase Secondary Outcome: To generate single dose PK data for the new tablet formulation in man, and to generate information on dose linearity for the new tablet formulation Blood samples (12) will be taken at pre-defined intervals prior to and following dosing of a single capsule and a single tablet dose To determine the safety and tolerability of AZD2281 for both the new tablet formulation and existing capsule formulations every 28 days Randomised tablet formulation continued supply expansion phase (Group 8): To determine the single dose and steady state exposures achieved with the selected table dose schedules of AZD2281 melt-extrusion (tablet) formulation at every visit Continued Supply Expansion Phase: To compare the steady state exposure achieved with 200mg bid tablet formulation and 400mg bid capsule formulation at visit 3 and visit 4 Dose Escalation Phase of the continued supply expansion: To determine the single dose and steady state exposures achieved with higher doses of AZD2281 tablet formulation at every visit Dose Escalation Phase of the continued supply expansion: To describe the efficacy data observed in patients treated with the capsule formulation and the tablet formulation at every visit Continued Supply Expansion Phase: To describe the efficacy data observed in patients treated with the capsule and the tablet RECIST, Progression Free Survival, Best overall response and CA-125 response Randomised tablet formulation continued supply expansion phase (Group 8): To obtain a preliminary assessment of the effect of food on the exposure to AZD2281 following dosing of the melt-extrusion (tablet) formulation. at every visit Randomised tablet formulation continued supply expansion phase (Group 8): To describe the efficacy data observed in patients treated with the melt-extrusion (tablet) formulation at every visit
