Atara Biotherapeutics Announces First Quarter 2015 Results

SOUTH SAN FRANCISCO, Calif., May 7, 2015 (GLOBE NEWSWIRE) -- Atara Biotherapeutics, Inc. (Nasdaq: ATRA), a biopharmaceutical company with a focus on developing innovative therapies for patients with debilitating diseases, today reported financial results for the first quarter ended March 31, 2015.

"The first quarter was an active period for Atara," said Isaac Ciechanover, CEO of Atara. "We achieved important strategic and operational milestones across all of our pipeline product candidates and optioned programs."

First Quarter 2015 Strategic and Operational Highlights

  • Completed an underwritten public offering of common stock raising net proceeds of approximately $69.5 million
  • Continued accrual of patients into our Phase 2 PINTA 745 clinical study in End Stage Renal Disease patients with Protein Energy Wasting and into our Phase 1 dose escalation study of STM 434 in patients with advanced solid tumors, including ovarian cancer
  • Breakthrough Therapy Designation granted to our collaborative partner, Memorial Sloan Kettering Cancer Center (MSK), by the U.S. Food and Drug Administration (FDA) for Epstein-Barr Virus Targeted T-cells (EBV-CTL) in the treatment of patients with rituximab-refractory, EBV-associated lymphoproliferative disease (EBV-LPD), a type of malignancy occurring after allogeneic hematopoietic cell transplantation (HCT)
  • Augmented executive team, including hiring a Head of Immunotherapy to lead our efforts in our collaboration with MSK
  • Collaborative partner, MSK, invited to present clinical data on EBV-CTL at a clinical trials plenary session at the 2015 American Association for Cancer Research Annual Meeting

First Quarter 2015 Financial Results

  • The company reported a net loss of $9.2 million, or $0.42 per share, for the first quarter of 2015, compared to a net loss of $7.0 million, or $5.58 per share, for the first quarter of 2014. The increase in net loss in the 2015 period was primarily due to higher costs related to expanded clinical development activities related to our clinical and preclinical development activities and optioned T-cell programs.
  • Research and development expenses increased to $5.8 million for the first quarter of 2015, compared to $3.0 million for the first quarter of 2014, which included an increase of $1.4 million for expanded clinical development activities and $1.4 million increased payroll related costs from increased headcount and stock-based compensation.
  • General and administrative expenses decreased to $3.5 million for the first quarter of 2015, compared to $4.1 million for the first quarter of 2014. The decrease is primarily due to a $1.4 million decrease in stock-based compensation costs, partially offset by higher payroll-related costs from increased headcount and higher administrative costs, director and officer insurance premiums and investor relations costs associated with being a public company.
  • As of March 31, 2015, the company had approximately $166.7 million in cash and cash equivalents and short-term available-for-sale investments.
