Here it is in comparison to Lily's Retevmo (pralset first then retevmo)
ORR in those previously tx with platinum therapy: 61% vs 64%

ORR in treatment naive pts: 73% vs 85%
CRR in treatment naive pts: 12% vs 0%

>6mo duration of response: 86% across all lines of tx vs Retevmo's 81% (previously tx with platinum) and Retevmo's 58% in those that were tx naive

no CNS progression events, all had brain met shrinkage, no new brain mets while on pralsetinib. (91% with retevmo).

retevmo is twice daily dosing, pralsetinib is once daily.

BPMC data look similar on first glance. I'm not an oncologist, but if I was, and all else being equal, I think I would favor a 12% chance at a complete response with a lower ORR rate with close monitoring with a low threshold to change treatment if worsening. This may ultimately end up being in the hands of marketing/sales teams, and pricing with insurance companies.

Generally, a win for patients either way (hopefully).
