Aimmune Therapeutics Announces Second Quarter 2018 Financial Results

Aimmune Therapeutics, Inc. (Nasdaq: AIMT), a biopharmaceutical company developing treatments for life-threatening food allergies, today announced financial results for the quarter and six months ended June 30, 2018. As of June 30, 2018, cash, cash equivalents and investments totaled $295.9 million.

"Since joining Aimmune in mid-June, I have been enormously pleased to see a strong team in place and solid progress towards submitting a Biologics License Application for AR101 in peanut allergy by the end of this year,” said Jayson Dallas, M.D., President and CEO of Aimmune. "Our intention in developing AR101 is to provide a reliable, robust level of protection with the convenience of daily oral dosing so that people living with peanut allergy can have peace of mind and more freedom in their daily lives. We are laser focused on continuing to move AR101 towards potential approval and preparing for a potential U.S. commercial launch in 2019. With an estimated 1.6 million peanut-allergic children and adolescents in the United States alone, we believe the market opportunity is very large. We are motivated by the widespread enthusiasm we hear from allergists and patients who are eager for an approved biologic oral immunotherapy. It is truly exciting to lead Aimmune into its next phase of becoming a fully integrated commercial organization with a pipeline of opportunities in other significant food allergies. I look forward to sharing our progress in the months ahead.”

Second Quarter Highlights

AR101: Pivotal-stage biologic for the treatment of peanut allergy

• Announced new clinical data at the Congress of the European Academy of Allergy, Asthma, and Immunology (EAACI) showing efficacy across the intent-to-treat population of peanut-allergic patients enrolled in the Phase 3 PALISADE trial of AR101.
• Announced results from an Aimmune-supported survey of more than 100 U.S. allergists showing that more than 80 percent preferred the term "tolerated dose” as the most clinically meaningful relevant term to communicate desensitization levels to oral immunotherapy patients.
• Announced results from a new pan-European study showing significant psychosocial burden associated with peanut allergy, with a daily impact on more than 80 percent of people with peanut allergy and parents or caregivers of peanut-allergic minors.

Corporate

• Appointed Dr. Jayson Dallas, an experienced leader with an extensive record of global strategic and commercial operational accomplishments and successful product launches, as President and Chief Executive Officer.

Second Quarter Financial Results

For the quarter and six months ended June 30, 2018, net loss was $52.6 million and $102.1 million, respectively, compared to net loss of $32.5 million and $58.4 million for the comparable periods in 2017.

On a per share basis, net loss for the quarter and six months ended June 30, 2018, was $0.91 and $1.83, respectively, compared to net loss per share of $0.65 and $1.16 for the comparable periods in 2017. The weighted average shares outstanding for the quarter and six months ended June 30, 2018 was 57.9 million and 55.8 million, respectively, compared to 50.2 million shares for the comparable periods in 2017. In the first quarter of 2018, the Company completed an underwritten public offering with net proceeds of $190.4 million through the sale and issuance of an aggregate of 6,325,000 shares of common stock.

Research and development expenses for the quarter and six months ended June 30, 2018, were $35.3 million and $68.7 million, respectively, compared to $22.2 million and $39.6 million for the comparable periods in 2017. The increase was primarily due to higher costs from the progression of certain AR101 clinical trials, including RAMSES, ARC008, ARC009, ARTEMIS and ARC011, and higher contract manufacturing costs to support clinical development and regulatory activities.

General and administrative expenses for the quarter and six months ended June 30, 2018, were $18.6 million and $35.2 million, respectively, compared to $10.8 million and $19.7 million for the comparable periods in 2017. The increase was primarily due to additional employee-related costs and external professional services as Aimmune continues to build its infrastructure to support the development and potential commercialization of AR101. Stock-based compensation expense also increased primarily due to the expansion and extension of our long-term commercial supply agreement with Golden Peanut Company and modification of certain executives’ stock options resulting from their planned separation.

Cash, cash equivalents, and investments totaled $295.9 million at June 30, 2018, compared to $182.4 million at December 31, 2017. The increase primarily reflects net cash proceeds of $190.4 million received as of June 30, 2018, from the sale of common stock, partially off-set by cash used in operating activities of $76.3 million and cash used for purchase of plant and equipment of $6.2 million.
