On an intent-to-treat (ITT) basis for the 125 enrolled patients, the median progression-free survival (PFS) was 5.6 months on the Telcyta plus PLD arm compared to 3.7 months on the PLD control arm, p = 0.7243 and hazard ratio (HR) = 0.92.

Of the 125 patients in the ITT population, a prespecified analysis was conducted for 75 patients with platinum refractory or primary platinum resistant disease, including 40 patients on the Telcyta plus PLD arm and 35 patients on the PLD control arm. The median PFS of these patients was 5.6 months for the Telcyta plus PLD arm compared to 2.9 months for the PLD control arm, p = 0.0425 and HR = 0.55. The response rate, as assessed by RECIST, was 15%, including one CR for the Telcyta plus PLD arm and 6% for the PLD control arm.
