Roche of­fers an up­beat two-plus-year look at its an­ti-TIG­IT com­bo ther­a­py — but will two deaths hurt its chances?

Roche’s Genen­tech got a leg up in the packed an­ti-TIG­IT race ear­li­er this year when the FDA grant­ed it the first break­through des­ig­na­tion in the field based on some up­beat mid-stage da­ta in non-small cell lung can­cer. Now, look­ing to keep its lead, the phar­ma gi­ant is of­fer­ing a two-and-a-half-year look at the same pa­tient group — but will two deaths crush its chances?

A com­bi­na­tion of Genen­tech’s an­ti-TIG­IT can­cer tiragolum­ab plus PD-L1 in­hibitor Tecen­triq re­duced pa­tients’ risk of dis­ease pro­gres­sion or death by 38% com­pared to those who re­ceived Tecen­triq alone at a me­di­an fol­low-up of 2.5 years, the com­pa­ny said on Fri­day. In a pre-spec­i­fied ex­plorato­ry analy­sis of par­tic­i­pants with high lev­els of PD-L1, the com­bo re­duced the risk of dis­ease wors­en­ing or death by 71% com­pared to the Tecen­triq group.
