['pembro', 'kn-789', 'lcsm,(-blcsm)']
kn-789, chemo/pembro v chemo/placebo: signif benefit in pfs, non-signif trend in os favoring pembro arm. though this will likely lead to chemo as clearly favored next rx in acquired resistance, os is more favorable in those w/pd-l1+. wonder what anti-vegf would add #asco23 #lcsm
