In any study phase, individuals could withdraw consent or become lost to follow-up Effectiveness Forty-nine individuals (79.0%) in the olaratumab+liposomal doxorubicin arm and 47 individuals (77.0%) in the liposomal doxorubicin arm had a total of 96 PFS events. Median PFS was related between organizations (stratified HR?=?1.043; em p /em ?=?0.837) (Fig.?2a). The 1-yr PFS rate was 16.9% in the olaratumab+liposomal doxorubicin arm and 12.5% in the liposomal doxorubicin arm. Open in a separate windowpane Fig. 2 Kaplan-Meier plots of progression-free (a) and overall (b) survival In the platinum-refractory subgroup, median PFS appeared slightly longer in the olaratumab+liposomal doxorubicin arm than in the liposomal doxorubicin arm (5.5?weeks vs 3.7?weeks [HR?=?0.85; 95% CI 0.38C1.91]) (Table?3). In the platinum-resistant subgroup, median PFS was related between organizations (3.7?weeks in the olaratumab+liposomal doxorubicin arm vs 4.0?weeks in the liposomal doxorubicin arm; [HR?=?1.13; 95% CI 0.71C1.80]) (Table ?(Table33).

Similarly, individuals with a lower CA125 (64.3) had higher PFS with olaratumab+liposomal doxorubicin treatment compared with individuals in the liposomal doxorubicin arm, achieving an HR of 0.5 (95% CI 0.21C1.22) ( em n /em ?=?27). It should be noted the 95% CIs for everyone considered subgroups.
