Pharmaceutical US Food and Drug Administration approvals dominated much of the news last week. Among these was the FDA’s approval of Regeneron’s Libtayo, marking the firm’s entry into the immuno-oncology sector. The FDA also cleared for marketing: Pfizer’s Vizimpro for a rare form of lung cancer; Paratek’s antibiotic Nuzyra and acne drug Seysara; and Roche’s hemophilia A drug Hemlibra in a much wider patient population, so boding well for the Swiss pharma giant’s moves to expand out of its core oncology franchise that is facing copycat competition. On the deal-making front, there was the unexpected news that Janssen is pulling out of its agreement with Aduro Biotech on cancer drug candidates. 7 October 2018
