Totals for aggregate deals and in the M&A, alliance and divestment categories were similar among the 10 busiest deal makers from 2020 to 2021, but COVID-19 may have driven a more hectic deal-making pace overall in 2020.

Ventus Therapeutics raised a $140m series C while Endeavor Biomedicines brought in $101m in series B cash. Also, Twist Bioscience grossed $250m in a follow-on offering, BioMarin raised $110m when it sold a priority review voucher and Nuvectis, TC BioPharm launched IPOs. 

Initial public offering momentum decelerated as stock prices declined last year, but even with lower valuations making M&A more attractive, the IPO market this year is expected to be active. 

Ahead of the usual flurry of deal-making in January, Roche gets retinal cell therapy candidate from Lineage Cell Therapeutics, Pfizer subsidiary Amplyx licenses antiviral candidate to Vera, and GSK expands neurology tie-up with Ligand.
