BioNTech's $270m Series A round was the biggest start-up financing in January, but sizeable rounds also were raised by Centrexion ($67m), Eureka ($60m) and Pandion ($58m).

Pandion, led by former Pfizer SVP Anthony Coyle, launched in 2017 to exploit immuno-oncology advances for autoimmune and inflammatory diseases; the firm's Series A follows a record-breaking year for biopharma venture capital. In public company financings, AveXis and others seek cash to fuel R&D.

Gilead licensed rights to four preclinical antibodies from MacroGenics. Stryker bought Chinese device company Trauson for $751 million. Biopharma companies raised double the amount from December, bringing in $2.8 billion, while device funding dropped to $269 million.
