SOUTH SAN FRANCISCO, Calif., Nov. 06, 2018 (GLOBE NEWSWIRE) -- Atara Biotherapeutics, Inc. (Nasdaq: ATRA), a leading off-the-shelf, allogeneic T-cell immunotherapy company developing novel treatments for patients with cancer, autoimmune and viral diseases, today reported financial results for the third quarter of 2018 and recent operational progress.
“We made important progress in the third quarter advancing our off-the-shelf, allogeneic T-cell immunotherapy pipeline,” said Isaac Ciechanover, M.D., Chief Executive Officer and President of Atara Biotherapeutics. “We recently announced a strategic collaboration with Moffitt Cancer Center to expand our next-generation CAR T immunotherapy pipeline and initiated a Phase 1/2 clinical study of tab-cel® in combination with Merck's KEYTRUDA® for patients with EBV-associated nasopharyngeal carcinoma. This is an exciting period for Atara and we look forward to updating you on additional pipeline results at the ASH and ESMO IO scientific congresses in December.”
Atara continues to advance its tab-cel® (tabelecleucel) Phase 3 studies for patients with Epstein-Barr virus associated post-transplant lymphoproliferative disorder (EBV+ PTLD) and anticipates initial tab‑cel® Phase 3 results in the first half of 2019. The Company is in ongoing discussions with the European Medicines Agency (EMA) and U.S. Food & Drug Administration (FDA) regarding the development and regulatory paths for tab‑cel® based on its experience conducting the Phase 3 studies in patients with this life-threatening condition. The Company plans to share initial Phase 3 clinical results as well as observed EBV+ PTLD incidence with these agencies. The outcomes of both regulatory discussions are expected in the first half of 2019, and Atara now plans to submit a tab‑cel® EU conditional marketing authorization (CMA) application in the second half of 2019.
Atara continues to build its pipeline and operational capabilities as well as prepare for the launch of its first commercial product. Initial results from the off-the-shelf, allogeneic ATA188 multiple sclerosis program are anticipated in the first half of 2019. In addition, the Company is rapidly advancing its next-generation chimeric antigen receptor T-cell (CAR T) pipeline across multiple therapeutic areas and expects to highlight results at upcoming events.
Recent Highlights and Anticipated Upcoming Milestones

Third Quarter 2018 Financial Results
- Cash, cash equivalents and short-term investments as of September 30, 2018 totaled $364.5 million, which the Company believes will fund planned operations to mid-2020.
- The Company reported net losses of $58.4 million, or $1.29 per share, for the third quarter of 2018, as compared to $31.1 million, or $1.02 per share, for the same period in 2017.
- In the third quarters of 2018 and 2017, total operating expenses of $60.2 million and $31.7 million included non-cash expenses of $10.4 million and $6.3 million, respectively.
- Research and development expenses were $43.4 million for the third quarter of 2018, as compared to $20.6 million for the same period in 2017. The increase in the third quarter of 2018 was due to costs associated with the Company’s continuing expansion of research and development activities, including:
- clinical trial, manufacturing and outside service costs related to the two Phase 3 clinical trials of tab-cel® in patients with EBV+ PTLD and the Phase 1 clinical trial of allogeneic ATA188 in patients with MS, and
- higher employee-related and overhead costs from increased headcount and operations.
- Research and development expenses include $4.7 million and $2.1 million of non-cash stock-based compensation expenses in the third quarters of 2018 and 2017, respectively.
- General and administrative expenses were $16.9 million for the third quarter of 2018, as compared to $11.1 million for the same period in 2017. The increase in the third quarter of 2018 was primarily due to increases in professional services costs and employee-related costs from increased headcount to support the Company’s expanding operations. General and administrative expenses include $4.6 million and $3.9 million of non-cash stock-based compensation expenses in the third quarters of 2018 and 2017, respectively.
