2seventy Bio initiated with a Buy at Guggenheim 06:56 TSVT, BMY Guggenheim analyst Kelsey Goodwin initiated coverage of 2seventy Bio (TSVT) with a Buy rating and $30 price target as she starts coverage of five biotech stocks pursuing "innovative approaches to cell therapy." 2seventy has "been a pioneer of anti-BCMA CAR-T cell therapy" and together with partner Bristol-Myers (BMY) secured FDA-approval of the first CAR-T therapy in multiple myeloma, Abecma, last March, Goodwin tells investors. She does not think 2seventy's current valuation reflects the full commercial potential of Abecma, given the view that patient demand for anti-BCMA CAR-T cell therapies "vastly exceeds current commercial availability," providing room for several commercial competitors, Goodwin said.
