Atara Biotherapeutics Announces Second Quarter 2019 Financial Results and Recent Operational Progress


SOUTH SAN FRANCISCO, Calif., Aug. 08, 2019 (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 second quarter of 2019 and recent operational highlights.

“I am confident we are now in a strong position to execute and create value across our tab-cel®, multiple sclerosis and next-generation CAR T programs,” said Pascal Touchon, President and Chief Executive Officer of Atara Biotherapeutics. “We believe our updated tab-cel® development strategy, focusing on initiating an EBV+ PTLD regulatory submission first in the United States, prioritizes the most attractive market for such an ultra-rare disease and advances our mission to bring transformative T-cell immunotherapies to patients in critical need. In addition, we are encouraged by the initial safety results from our ongoing ATA188 Phase 1 study for patients with progressive MS and look forward to presenting the initial efficacy results from this study in September. We also strengthened our financial position, funding planned operations into 2021 and through key milestones next year including initiating the tab-cel® BLA submission and next-generation mesothelin CAR T IND.”

Recent Highlights and Anticipated Upcoming Milestones

Tab-cel® (tabelecleucel)

  • Atara continues to progress tab-cel® Phase 3 development for patients with Epstein-Barr virus associated post-transplant lymphoproliferative disease (EBV+ PTLD).
    • Based on discussions with the U.S. Food & Drug Administration (FDA), Atara plans to initiate a tab-cel® biologics license application (BLA) submission for patients with EBV+ PTLD in the second half of 2020.
    • In the United States and Australia, 34 sites are available for enrollment and the company is preparing to open additional sites in the United States, Europe and Canada.
       
  • We continue to see strong tab-cel® investigator, physician and patient interest and, in cases where we are not able to enroll patients in our EBV+ PTLD Phase 3 clinical studies, we are providing tab-cel® to patients in need under our early access and single patient use programs.
     
  • Atara is in discussions with the European Medicines Agency (EMA) and the outcome of these discussions will determine the timing of the tab-cel® EU conditional marketing authorization (CMA) application for patients with EBV+ PTLD.
     
  • Studies supporting potential additional tab-cel® indications are also advancing. 
    • A Phase 1/2 clinical study of tab-cel® in combination with Merck's anti-PD-1 (programmed death receptor-1) therapy, KEYTRUDA® (pembrolizumab), in patients with platinum-resistant or recurrent EBV-associated nasopharyngeal carcinoma (NPC) is currently enrolling.
    • Atara expects to initiate a Phase 2 multi-cohort study including patients with other EBV+ cancers in the second half of 2020.

                         
ATA188 & ATA190 for Multiple Sclerosis (MS)

  • A Phase 1 clinical study of off-the-shelf, allogeneic ATA188 in patients with progressive MS is ongoing across clinical sites in the United States and Australia.
    • Initial ATA188 Phase 1 safety results for patients with progressive MS were presented at the 5th Congress of the European Academy of Neurology (EAN). The first three ATA188 dose cohorts were well tolerated with no dose-limiting toxicities and no =3 grade treatment-related, treatment-emergent adverse events.
    • Atara plans to present initial efficacy and additional safety results from this study at the 35th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) to be held September 11-13 in Stockholm, Sweden.
    • A randomized, double-blind, placebo-controlled Phase 1b part of this study using the recommended Phase 2 dose (RP2D) is now planned following completion of the open-label, dose-escalation period.
       
  • Atara expects to initiate a randomized study of autologous ATA190 in progressive MS patients during the second half of 2019.

             
Next-Generation CAR T

  • Positive Phase 1 clinical results for a mesothelin-targeted CAR T immunotherapy in patients with advanced mesothelioma were presented at the American Society of Clinical Oncology (ASCO) Annual Meeting 2019.
    • Memorial Sloan Kettering Cancer Center (MSK) collaborators presented results demonstrating that their regionally delivered mesothelin-targeted, autologous CAR T cells were well tolerated and showed encouraging anti-tumor activity in combination with pembrolizumab, a PD-1 checkpoint inhibitor.
    • In a subset of 16 malignant pleural mesothelioma patients with minimum follow-up time of 3 months who also received pembrolizumab and lymphodepleting chemotherapy, 12-month overall survival was 80% and best overall response rate was 63%, including 3 investigator-assessed complete responses.
       
  • Atara prioritized the mesothelin-targeted next-generation CAR T program, with an IND planned for autologous ATA2271 in advanced mesothelioma in 2020.

             
Corporate

  • Pascal Touchon was appointed President, Chief Executive Officer and member of the Board of Directors. Prior to joining Atara in June, Dr. Touchon served as Novartis Oncology Global Head, Cell & Gene and member of the Oncology Executive Committee.
     
  • Atara completed facility commissioning and qualification activities to support clinical operations at ATOM (Atara T-cell Operations and Manufacturing).
    • Commercial production qualification activities are nearing completion and, together with our contracted manufacturing partner, are aligned with our planned commercial strategy.

             

Second Quarter 2019 Financial Results

  • Cash, cash equivalents and short-term investments as of June 30, 2019 totaled $190.1 million. In July 2019 we sold approximately 6.9 million shares of common stock and pre-funded warrants to purchase approximately 2.9 million shares of common stock for net proceeds of $140.6 million in an underwritten public offering.
  • The Company believes the net proceeds from the offering, together with existing cash, cash equivalents and short-term investments, are sufficient to fund planned operations into 2021.
  • The Company reported net losses of $74.3 million, or $1.60 per share, for the second quarter of 2019 as compared to $50.9 million, or $1.15 per share, for the same period in 2018.
  • Total operating expenses include total non-cash expenses of $16.9 million for the second quarter of 2019 as compared to $8.7 million for the same period in 2018.
  • Research and development expenses were $52.3 million for the second quarter of 2019 as compared to $33.4 million for the same period in 2018. The increase in the second quarter of 2019 was due to costs associated with the Company’s continuing expansion of research and development activities, including:
      °  clinical study, manufacturing and outside service costs related to our tab-cel®, ATA188 and ATA190 programs, including strategic spending to build inventory for clinical studies and potential commercialization;
      °  higher employee-related and overhead costs from increased headcount and operations, and
      °  an increase in facilities and information technology expenses that are attributed to our research and development function.
  • Research and development expenses include $6.7 million of non-cash stock-based compensation expense for the second quarter of 2019 as compared to $3.4 million for the same period in 2018.
  • General and administrative expenses were $23.3 million for the second quarter of 2019 as compared to $19.2 million for the same period in 2018. The increase in the second quarter of 2019 was primarily due to increases in professional services costs and employee-related costs driven by increased headcount to support the Company’s expanding operations.
  • General and administrative expenses include $8.5 million of non-cash stock-based compensation expense for the second quarter of 2019 as compared to $4.6 million for the same period in 2018.
