Merck hits another Keynote in perioperative lung

Merck & Co’s Keytruda had already hit on one co-primary endpoint of its (neo)adjuvant non-small cell lung cancer trial, Keynote-671. Now the company has said the study met its other co-primary measure, overall survival – marking the first time a PD-(L)1 inhibitor has shown a survival benefit. No data are yet available but investors won’t have long to wait, with results slated for the ESMO meeting this month. Before that, though, Keytruda is facing a US approval decision by 16 October for the new perioperative use, based on improvement in event-free survival. Keynote-671 involved Keytruda plus chemo before surgery (neoadjuvant), followed by resection and single-agent Keytruda afterwards (adjuvant). The checkpoint inhibitor players have been duelling in the perioperative space, with Bristol Myers Squibb recently announcing a win in its rival (neo)adjuvant trial CheckMate-77T; data from that study are also due at ESMO. However, Roche, once a leader in this setting, has fallen behind, with its neoadjuvant Impower-030 study delayed.
