Aimmune Therapeutics, Inc. (Nasdaq: AIMT), a biopharmaceutical company developing and commercializing treatments for potentially life-threatening food allergies, today announced that Nestlé Health Science will make an additional equity investment in Aimmune of $200 million, bringing Nestlé’s total investment in Aimmune to date to $473 million.

“Nestlé Health Science has been an important equity investor and strategic partner to Aimmune since we entered into our original collaboration in 2016, and we are grateful for their ongoing commitment toward our mutual goal of developing innovative therapies for food allergies,” said Jayson Dallas, M.D., President and CEO of Aimmune Therapeutics. “This additional capital strengthens our financial position as we prepare to launch PALFORZIA™, the first FDA-approved medicine for peanut allergy in the U.S. In addition, this capital will help fund the continued advancement of our pipeline, including conducting clinical trials of AIMab7195 which we recently in-licensed from Xencor.”

The Nestlé Health Science investment includes the purchase of 1,000,000 shares of Aimmune common stock and 525,634 shares of convertible preferred stock, convertible on a one-for-ten shares of common stock basis in certain circumstances and subject to certain limitations. The convertible preferred stock has a liquidation preference of $0.0001 per share, does not have any voting rights, and has no stated dividend. In connection with this transaction, certain terms of Aimmune’s agreements with Nestlé Health Science have been extended by one year until November 11, 2021.

“Our collaboration with Aimmune aligns with our mission to provide innovative nutritional health solutions that are supported by science and research,” said Greg Behar, CEO of Nestlé Health Science. “We are impressed with the progress Aimmune has made as it prepares to launch PALFORZIA, the first drug approved by the FDA for any form of food allergy. As part of our ongoing commitment to the advancement of science-based nutritional health solutions, our further investment in Aimmune is intended to help assure PALFORZIA’s longer-term commercial success and allow Aimmune to continue making significant development advances in the field of food allergy treatments.”

Upon closing of the equity investment, Aimmune will receive a payment of $200 million in connection with Nestlé Health Science’s purchase of 1,000,000 newly issued shares of Aimmune’s common stock at $31.97 per share, based on the most recent five-day volume weighted average stock price and 525,634 shares of convertible preferred stock priced at $319.675 per share. The preferred stock is convertible to common stock on a one-for-ten basis. After the completion of the transaction, Nestlé Health Science’s total investments in Aimmune will correspond to ownership of 19.9% of Aimmune’s outstanding common stock and voting power, and 25.6% overall stake in the company’s fully-diluted capitalization. The companies expect to close the equity investment on February 7, 2020, subject to satisfaction of usual and customary closing conditions.

INDICATION

PALFORZIA is an oral immunotherapy indicated for the mitigation of allergic reactions, including anaphylaxis, that may occur with accidental exposure to peanut. PALFORZIA is approved for use in patients with a confirmed diagnosis of peanut allergy. Initial Dose Escalation may be administered to patients aged 4 through 17 years. Up-Dosing and Maintenance may be continued in patients 4 years of age and older.

PALFORZIA is to be used in conjunction with a peanut-avoidant diet.

Limitations of Use: Not indicated for the emergency treatment of allergic reactions, including anaphylaxis.

IMPORTANT SAFETY INFORMATION

Boxed WARNING:

PALFORZIA can cause anaphylaxis, which may be life threatening and can occur at any time during PALFORZIA therapy.

Prescribe injectable epinephrine, instruct and train patients on its appropriate use, and instruct patients to seek immediate medical care upon its use.

Do not administer PALFORZIA to patients with uncontrolled asthma.

Dose modifications may be necessary following an anaphylactic reaction.

Observe patients during and after administration of the Initial Dose Escalation and the first dose of each Up-Dosing level, for at least 60 minutes.

PALFORZIA is available only through a restricted program called the PALFORZIA REMS.

CONTRAINDICATIONS

PALFORZIA is contraindicated in patients with uncontrolled asthma, or with a history of eosinophilic esophagitis and other eosinophilic gastrointestinal disease.

WARNINGS AND PRECAUTIONS

Anaphylaxis

PALFORZIA can cause anaphylaxis, which may be life threatening. PALFORZIA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the PALFORZIA REMS because of the risk of anaphylaxis. Only prescribers, healthcare settings, pharmacies, and patients certified and enrolled in the REMS Program can prescribe, receive, dispense or administer PALFORZIA.

Anaphylaxis has been reported during all phases of PALFORZIA dosing, including Maintenance and in subjects who have undergone recommended Up-Dosing and dose modification procedures.

Do not initiate PALFORZIA treatment in a patient who has had severe or life-threatening anaphylaxis within the previous 60 days. PALFORZIA may not be suitable for patients with certain medical conditions that may reduce the ability to survive anaphylaxis, including but not limited to markedly compromised lung function, severe mast cell disorder, or cardiovascular disease. In addition, PALFORZIA may not be suitable for patients taking medications that can inhibit or potentiate the effects of epinephrine.

All Initial Dose Escalation doses and the first dose of each Up-Dosing level must be administered in a certified health care setting.

Patients may be more likely to experience allergic reactions following PALFORZIA administration in the presence of cofactors such as exercise, hot water exposure, intercurrent illness (e.g., viral infection), or fasting. Other potential cofactors may include menstruation, sleep deprivation, nonsteroidal anti-inflammatory drug use, or uncontrolled asthma. Patients should be proactively counseled about the potential for the increased risk of anaphylaxis in the presence of these cofactors. If possible, adjust the time of dosing to avoid these cofactors. If it is not possible to avoid these cofactors, consider withholding PALFORZIA temporarily.

Asthma

Uncontrolled asthma is a risk factor for a serious outcome, including death, in anaphylaxis. Ensure patients with asthma have their asthma under control prior to initiation of PALFORZIA.

PALFORZIA should be temporarily withheld if the patient is experiencing an acute asthma exacerbation. Following resolution of the exacerbation, resumption of PALFORZIA should be undertaken cautiously. Re-evaluate patients who have recurrent asthma exacerbations and consider discontinuation of PALFORZIA.

Eosinophilic Gastrointestinal Disease

Discontinue PALFORZIA and consider a diagnosis of eosinophilic esophagitis in patients who experience severe or persistent gastrointestinal symptoms, including dysphagia, vomiting, nausea, gastroesophageal reflux, chest pain, or abdominal pain.

Gastrointestinal Adverse Reactions

Gastrointestinal adverse reactions were commonly reported in PALFORZIA-treated subjects, and dose modification should be considered for patients who report these reactions. For severe or persistent gastrointestinal symptoms consider a diagnosis of eosinophilic esophagitis.

ADVERSE REACTIONS

The most common adverse events reported in subjects treated with PALFORZIA (incidence ≥ 5% and ≥ 5% than placebo) are abdominal pain, vomiting, nausea, oral pruritus, oral paresthesia, throat irritation, cough, rhinorrhea, sneezing, throat tightness, wheezing, dyspnea, pruritus, urticaria, anaphylactic reaction, and ear pruritus.
