The two best-selling checkpoint inhibitors — Merck’s Keytruda and Bristol Myers Squibb’s Opdivo — are now approaching their patent cliffs.

Rachlin, co-founder and managing partner of the life sciences VC firm Ascenta Capital, told Endpoints News.

Rachlin, whose firm invested in the recently acquired Tubulis. |
