Atara Biotherapeutics Stock Jumps 18% as FDA Shake-Up Puts Ebvallo Back in Focus
Atara Biotherapeutics shares jumped 18% Monday after reports that FDA biologics chief Vinay Prasad will depart in April. The move follows the agency’s January rejection of Atara’s EBVALLO therapy for a rare blood cancer, which wiped out 56% of the stock’s value. Atara and partner Pierre Fabre have requested a Type A meeting with the FDA to revisit the decision. Atara ended 2025 with $8.5 million in cash.
