Study Endpoints

Primary Endpoints

Evaluate anti-tumour activity of FPI-2265 administered in combination with olaparib
From first dose until approximately 12 weeks after the first administered dose of FPI-2265

The frequency and proportion of participants with PSA50 response will be summarized, where PSA50 is defined as ≥50% decline in PSA level from pre-treatment.

Evaluate the safety and tolerability of FPI-2265 administered in combination with olaparib
From first dose until end of long-term follow-up, 5 years from the last administered dose of FPI-2265

Safety will be assessed by percentage of patient with treatment emergent adverse events and serious adverse events; percentage of patients with SAEs during the first year of the long term follow up and the number of AESIs during the 5 year follow up period. Percentage of patients with interruption of FPI-2265; percentage of patients who discontinue treatment; number and grade for AEs related to study treatment.
