Agios Pharmaceuticals (NASDAQ:AGIO), a biotech developing metabolic treatments for cancer and rare genetic diseases, rose 73.8% in its market debut. That made it the best biotech first-day return since Pain Therapeutics (NASDAQ:PTIE) rose 82.3% in its July 2000 debut.
The company raised $106 million in an upsized IPO that valued the company at a market cap of $542 million, after originally setting terms for a deal that would have generated $75 million in proceeds at a market cap of $441 million. Agios' opening day vaults it ahead of last week's IPO of OncoMed (NASDAQ:OMED), which saw its shares rise 59.9% on its first day of trading, for the best biotech first-day return in 2013. Agios is the fifth 2013 biotech deal to gain nearly 50% or more in its market debut.
