Item 8.01 | Other Events |
On May 30, 2019, Atara Biotherapeutics, Inc. (Atara or the Company) announced that Utpal Koppikar, the Companys Chief Financial Officer, will participate in the Jefferies 2019 Healthcare Conference on June 5, 2019 and the Goldman Sachs 40th Annual Global Healthcare Conference on June 13, 2019. Live audio webcasts of the presentations will be available by visiting the Investor Events and Presentations section of atarabio.com. Archived replays will be available on the Companys website for approximately 14 days following the live webcasts.
As part of the presentations, Atara intends to provide an update related to the Companys ongoing discussions with the U.S. Food and Drug Administration (the FDA) regarding the development of tab-cel®. Based on preliminary feedback from the FDA, the Company plans to combine two ongoing tab-cel® Phase 3 clinical studies (MATCH and ALLELE) which were originally designed for enrollment of around 100 total Epstein-Barr virus-associated post-transplant lymphoproliferative disease (EBV+ PTLD) patients into a single tab-cel® Phase 3 protocol (ALLELE). The planned amended ALLELE protocol consists of a hematopoietic cell transplants (HCT) cohort with approximately 33 EBV+ PTLD patients who have failed rituximab as well as a single solid organ transplants (SOT) cohort of approximately 33 EBV+ PTLD patients who have failed rituximab with both chemotherapy and non-chemotherapy prior treatment experience. The Company does not expect to change the primary endpoint for the two cohorts of the combined study.
