$121M lat­er, Langer-backed Se­lec­ta rais­es $70M more from its IPO

Se­lec­ta Bio­sciences ($SELB) land­ed on Nas­daq with a slight limp, rais­ing $70 mil­lion af­ter pric­ing a bumped-up batch of shares at $14 — the low end of its range.

In this mar­ket, for a biotech that isn’t di­rect­ly en­gaged in gene edit­ing, that’s cause for cel­e­bra­tion, though Se­lec­ta ex­ecs may choose from the less ex­pen­sive brands of Cham­pagne for the go­ing-pub­lic par­ty.

MIT in­ves­ti­ga­tor Robert Langer, Omid Farokhzad and Ul­rich von An­dri­an of the Har­vard Med­ical School pro­vid­ed the sci­en­tif­ic fire­pow­er re­quired to launch Wa­ter­town, MA-based Se­lec­ta, which has been steadi­ly ad­vanc­ing a new syn­thet­ic nanopar­ti­cle tech­nol­o­gy to block an un­want­ed im­mune sys­tem at­tack, thwart­ing an an­ti-drug an­ti­body re­sponse that can be kicked up by a va­ri­ety of bi­o­log­ics.
