What was measured

Time to CNS Progression per RECIST 1.1 by BICR (with or without Pembrolizumab)

Analysis population: CNS Overall: All participants included in the ITT population who had baseline CNS assessment and who had CNS metastasis at baseline. Participants censored: TRT A: 137; TRT B: = 73.

Groups in this outcome

Selpercatinib (TRT A)

160 mg Selpercatinib administered orally BID continuously in 21-day cycles.

Pemetrexed and Platinum With or Without Pembrolizumab (TRT B)

Pemetrexed 500 mg/m2, IV on Day 1 Q3W plus investigator's choice of carboplatin AUC 5 (maximum dose 750 mg) IV or cisplatin 75mg/m2, IV on Day 1 Q3W for 4 cycles, plus investigator's choice with or without 200 mg pembrolizumab IV on Day 1 Q3W up to 35 cycles.
