In the final overall survival (OS) analysis, statistical significance  was not met1
  • Subsequent treatments may have confounded survival outcomes: most patients received subsequent therapies (80.8% in TALZENNA arm, 76.4% in chemotherapy* arm); 59.7% in chemotherapy arm and 48.4% in TALZENNA arm received subsequent treatment with PARPi and/or platinum

Adapted from Litton et al. Ann Oncol. 2020.1OS adjusted for subsequent platinum and/or PARPi use1†‡§||   Adjusting for post-study PARP inhibition and/or platinum therapy reduced the HR and lowered the upper bound of the 95% Cl but did not reach statistical significance. Adapted from Litton et al. Ann Oncol. 2020.1
AEs=adverse events; Cl=confidence interval; DoR=duration of response; GHS=global health status; HR=hazard ratio; NS=not significant; ORR=objective response rate; PARP=poly (ADP-ribose) polymerase; PARPi=poly (ADP-ribose) polymerase inhibitor; QoL=quality of life; TTR=time to response.
Capecitabine, eribulin, gemcitabine, or vinorelbine. 
Statistical significance was not met when OS was adjusted for subsequent platinum and/or PARPi use. 
Most patients received subsequent therapies: 59.7% in the chemotherapy arm and 48.4% in the TALZENNA arm received subsequent treatment with a PARPi and/or platinum. 
Analysis using the rank-preserving structural failure time model (RPSFTM) method was performed. RPSFTM is a statistical method that was performed to estimate the treatment effect on OS adjusting for subsequent treatment with a PARPi and/or platinum. These analyses give an estimate of the treatment effect on OS, as if patients in the chemotherapy arm had not taken a PARPi and/or platinum after discontinuation of chemotherapy. 
Conducted in the intent-to-treat population.
