Atara Biotherapeutics stock dives on FDA EBVALLO rejection — what ATRA investors watch next
Atara Biotherapeutics shares fell 56% after the FDA rejected its cell therapy EBVALLO for a rare post-transplant cancer, citing insufficient evidence from the single-arm ALLELE study. The agency said previous manufacturing issues were resolved but requested new efficacy data. Atara and partner Pierre Fabre plan expedited talks with the FDA. The company reported $8.5 million in cash at year-end.
