SOUTH SAN FRANCISCO, Calif., Feb. 27, 2020 (GLOBE NEWSWIRE) -- Allogene Therapeutics, Inc. (Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) therapies for cancer, today provided a corporate update and reported fourth quarter and full-year 2019 financial results for the periods ended December 31, 2019.

"2019 was a very successful year for Allogene. We accomplished all of our corporate goals, which includes the establishment of world-class capabilities across multiple new functions and the initiation of our first clinical trials in patients with relapsed or refractory aggressive non-Hodgkin lymphoma and multiple myeloma," said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. "Our momentum and focus towards making AlloCAR T therapies and their life-saving potential a reality for patients will continue at full speed in 2020. This year will be an important one as we look to demonstrate proof-of-concept data from two key programs and plan for potential pivotal studies."

Recent Highlights

ALLO-501 (anti-CD19 AlloCAR T)

• In 2019, Allogene initiated the ALLO-501 Phase 1 ALPHA trial in patients with relapsed/refractory non-Hodgkin lymphoma (NHL). This study utilizes ALLO-647, Allogene's anti-CD52 monoclonal antibody (mAb) as a part of the lymphodepletion regimen. Initial data is planned to be presented at a medical meeting in Q2 2020.
• The U.S. Food and Drug Administration cleared the Investigational New Drug Application (IND) for ALLO-501A, the Company’s next generation anti-CD19 AlloCAR T construct devoid of the rituximab off-switch. ALLO-501A, previously referred to as ALLO-501.1, was created to eliminate the rituximab recognition domains in ALLO-501, allowing for use in a broader patient population, including those NHL patients with recent rituximab exposure.
• The Company expects to initiate an abbreviated Phase 1 portion of the ALLO-501A trial (ALPHA2) in the second quarter of the year. The ALPHA2 trial will leverage the findings of the ALPHA trial to finalize the ALLO-501A cell dose and the ALLO-647 based lymphodepletion regimen for a potential pivotal Phase 2 trial.

ALLO-715 (anti-BCMA AlloCAR T)

• The Company has created a robust anti-BCMA strategy centered around ALLO-715 for the treatment of multiple myeloma (MM).
• In 2019, Allogene initiated the ALLO-715 Phase 1 UNIVERSAL trial in patients with relapsed/refractory MM, designed to assess the safety and tolerability of ALLO-715.  This trial is also intended to identify the optimal dose of ALLO-647 and includes the potential to evaluate lymphodepletion regimens that do not include fludarabine and cyclophosphamide. UNIVERSAL continues to accrue as planned with initial data anticipated in Q4 2020.
• In January 2020, Allogene entered into a clinical collaboration with SpringWorks Therapeutics to evaluate ALLO-715 in combination with SpringWorks’ investigational gamma secretase inhibitor, nirogacestat, in patients with relapsed/refractory MM. The Company expects to initiate this combination trial in the second half of 2020.
• The Company nominated ALLO-605 as its first TurboCAR^TM candidate and part of its larger MM strategy. The TurboCAR technology provides the effects of cytokine stimulation to AlloCAR T cells with the goal of enhancing their potency, expansion and persistence. ALLO-605 is advancing in preclinical development with a potential IND in 2021.

Additional Pipeline Updates

• The Company nominated ALLO-316, an anti-CD70 AlloCAR T, as its next clinical candidate for potential development in acute myeloid leukemia, T-cell malignancies and/or renal cell carcinoma. Submission of the IND for ALLO-316 is expected by year end 2020.

Fourth Quarter Financial Results

• As of December 31, 2019, Allogene had $588.9 million in cash, cash equivalents, and investments.
• Research and development expenses were $49.4 million for the fourth quarter of 2019, which includes $6.4 million of non-cash stock-based compensation expense and $10.0 million in expenses associated with the signing of our collaboration with Notch Therapeutics.

• General and administrative expenses were $15.2 million for the fourth quarter of 2019, which includes $7.5 million of non-cash stock-based compensation expense. For the full year of 2019, general and administrative expenses were $57.5 million, which includes $26.6 million of non-cash stock-based compensation expense.
• Net loss for the fourth quarter of 2019 was $61.0 million, or $0.58 per share, including non-cash stock-based compensation expense of $13.9 million.
