What was measured
DOR was defined as the time from the first occurrence of a documented objective response (OR) to PD or death from any cause, whichever occurred first, as determined by the investigator with the use of RECIST v1.1. CR was defined as disappearance of all target lesions or any pathological lymph nodes must have reduction in short axis to \< 10 mm. PR was defined as at least a 30% decrease in the SOD of all target lesions, taking as reference the baseline SOD, in the absence of CR. PD was defined as at least a 20% increase in the SOD of target lesions, taking as reference the smallest SOD at prior timepoints, including baseline. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. K-M method was used to estimate median DOR. 95% CI for median was computed using the method of Brookmeyer and Crowley.
Analysis population: ITT population included all randomized participants whether or not the assigned study treatment is received. Overall number analyzed is the number of participants with an objective response of CR or PR. As specified in the protocol, assessment of this outcome measure was limited to Arms A and B, as the objective was to compare pralsetinib with SOC platinum-containing anticancer treatment regimens.
Groups in this outcome
Arm A: Treatment Period- SOC
Participants received platinum-containing anticancer treatment regimens (with or without pembrolizumab) at the study center as chosen by the treating investigator based on NSCLC histology. Participants with NSCLC of non-squamous histology received carboplatin + pemetrexed or cisplatin + pemetrexed or pembrolizumab + carboplatin + pemetrexed or pembrolizumab + cisplatin + pemetrexed. Participants with NSCLC of squamous histology received carboplatin or cisplatin + gemcitabine or carboplatin + paclitaxel/nab-paclitaxel + pembrolizumab until PD or for up to a maximum of 2 years.
Arm B: Treatment Period- Pralsetinib
Participants received pralsetinib, 400 mg, QD on Day 1 of each cycle until PD, PTAP, pralsetinib was no longer available, unacceptable toxicity, non-compliance, withdrawal of consent, closure of the study by the sponsor, or death, whichever occurred first (cycle length=21 days).
