Bris­tol-My­ers’ check­point star Op­di­vo fails a PhI­II study for glioblas­toma

Bris­tol-My­ers Squibb $BMY has had an­oth­er set­back on the check­point in­hi­bi­tion front, though this one they can take in stride.

Their big drug Op­di­vo failed to beat out Avastin in treat­ing re­cur­rent glioblas­toma, or brain can­cer, in im­prov­ing over­all sur­vival rates. In­ves­ti­ga­tors are hold­ing back the ac­tu­al da­ta for a pre­sen­ta­tion at an up­com­ing con­fer­ence in Zurich.

Check­mate-143 was the first ran­dom­ized study of a PD-1 check­point for glioblas­toma, says Bris­tol-My­ers, which is still pur­su­ing two first-line GBM clin­i­cal tri­als, Check­Mate -498 and Check­Mate -548, eval­u­at­ing the com­bi­na­tion of Op­di­vo with ra­di­a­tion ther­a­py with or with­out temo­zolo­mide in O6-methyl­gua­nine-DNA methyl­trans­ferase (MGMT)-un­methy­lat­ed and methy­lat­ed pa­tients.
