The information contains the preliminary outcomes the 2 firms introduced in December.
Amongst new information, practically 75% of sufferers who took the mixture had been alive with none indicators or signs of their most cancers returning on the 2½-year mark. That compares with 55.6% of sufferers who received Keytruda alone.
