Aimmune Therapeutics Announces First Quarter 2017 Financial Results

Aimmune Therapeutics, Inc. (Nasdaq: AIMT), a biopharmaceutical company developing CODIT™ (Characterized Oral Desensitization ImmunoTherapy) treatments for life-threatening food allergies, today announced financial results for first quarter 2017. As of March 31, 2017, cash, cash equivalents and investments totaled $259.3 million.

“We continue to be very pleased with progress in PALISADE, our core Phase 3 trial of AR101 for peanut allergy, and we look forward to expanding our Phase 3 program with initiation of the RAMSES trial in the second quarter and the ARTEMIS trial around mid-year,” said Aimmune CEO Stephen Dilly, M.B.B.S., Ph.D. “At AAAAI earlier this year, we reported interesting new data from the PALISADE screening population, which support our thesis for RAMSES whereby omitting the oral food challenge may further improve tolerability of AR101 during up-dosing. The level of interest and enthusiasm in our clinical trials remains very high, and we are pleased that most of the study sites in PALISADE will also participate in RAMSES.”

Dr. Dilly continued, “Over the first quarter, we also made key senior management hires focused on defining our path to market and initiating activities to plan for a potential commercial launch of AR101. In addition, as recently announced, we are delighted to have Eric Bjerkholt now on board as CFO. We continue to have substantial financial resources, and I look forward to reporting on our progress in the months ahead.”

First Quarter and Recent Corporate Highlights

Reported new AR101 clinical data at AAAAI. In March, Aimmune reported new clinical data at the American Academy of Allergy, Asthma & Immunology (AAAAI) annual meeting showing 95% adherence to daily at-home dosing with AR101 (Phase 2 data) and underscoring a high need for therapy based on 583 patients screened for PALISADE in North America. A subset analysis also showed that the oral food challenge appears to prime the immune system prior to treatment as the percent of activated CD4+ effector T cells were significantly higher after individuals underwent the oral food challenge as compared to their pre-challenge levels. This finding supports the design of the RAMSES trial, which does not require an oral food challenge.

Appointed healthcare industry veteran Eric Bjerkholt as CFO. In April, Aimmune announced the appointment of Eric Bjerkholt as CFO. Mr. Bjerkholt was most recently CFO at Sunesis Pharmaceuticals, Inc., where he oversaw multiple aspects of governance, corporate relations, and other functions. Prior to Sunesis, he was CFO at IntraBiotics Pharmaceuticals, Inc., and LifeSpring Nutrition, Inc. Mr. Bjerkholt began his healthcare career at J.P. Morgan & Co. as an investment banker in New York and then launched the company’s Western U.S. healthcare practice.

First Quarter Financial Results

Cash, cash equivalents, and investments totaled $259.3 million at March 31, 2017, compared to $282.5 million at December 31, 2016. The decrease primarily reflects cash used in operations.

Net loss was $25.9 million in the first quarter of 2017, compared to a net loss of $15.5 million for the comparable period in 2016. On a per share basis, net loss for the first quarter of 2017 was $0.52, compared to net loss per share of $0.37 for the comparable period in 2016. The weighted average shares outstanding for the quarter were 50.1 million, compared to 41.7 million for the comparable period in 2016.

Research and development expenses for the first quarter of 2017 were $17.4 million, compared to $10.0 million for the comparable period in 2016. The increase was primarily due to increased clinical trial and contract manufacturing costs and additional personnel-related costs, including stock-based compensation expense, to support the AR101 clinical development program.

General and administrative expenses for the first quarter of 2017 were $8.9 million, compared to $5.7 million for the comparable period in 2016. The increase was primarily due to additional personnel-related costs, including stock-based compensation expense, to support the achievement of the company’s goals.
