Aimmune’s food allergy treatments are investigational and are not FDA-approved

PALISADE Phase 3 Results Published in NEJM (Nov 18, 2018) “…treatment with AR101 resulted in higher doses of peanut protein that could be ingested without dose-limiting symptoms and in lower symptom severity during peanut exposure at the exit food challenge than placebo.” Vickery et al., NEJM, November 18, 2018 (online publication)

Executive Summary Aimmune Therapeutics is leading the field in developing novel treatments for food allergies New England Journal of Medicine publication highlights phase 3 PALISADE trial of AR101 Recently completed RAMSES phase 3 safety showed favorable safety profile; consistent with PALISADE In PALISADE, AR101 reduced the frequency and severity of reactions during the exit food challenge, which mimics accidental exposure We are on track to submit a Biologics License Application for AR101 in December We are preparing for a successful U.S. launch of AR101 in 2019, assuming approval

Peanut Allergy is One of the Most Common Food Allergies 4 out of 10 children with peanut allergy experienced a severe reaction over a 3-year period 8 out of 10 children with peanut allergy never outgrow it Over 1.6 million kids and teens affected in United States

Our Precision Medicine Approach Will Leverage the Oral Route Characterized allergen profile and FDA-regulated biologic products Convenient, once-daily oral dose taken with spoonfuls of food Research shows high levels of desensitization can be achieved with oral immunotherapy that may not be possible with other routes Goal of oral immunotherapy is to minimize the body’s reaction to trigger foods

Aimmune Therapeutics: Leading the Field in Developing Food Allergy Treatments Backed by rigorous science, our approach aims to transform food allergy treatment First-of-its-kind therapy to reduce the frequency and severity of peanut allergy reactions Food allergies are a growing, often life-threatening condition with no approved treatments Focused on reliable protection for patients and enabling allergists to be leaders in peanut allergy care

Largest and most rigorously conducted oral immunotherapy trial for peanut allergy ever reported First to use an independent blinded assessor DBPCFC at both baseline and exit First and only peanut OIT study to exceed the pre-specified, FDA-mandated superiority margin for efficacy First to accept participants with past medical history of severe or life-threatening anaphylaxis 12-month intervention period (6 months up-dosing, 6 months maintenance at 300 mg per day) PALISADE Was the Largest, Most Rigorous Phase 3 Trial of Immunotherapy for Peanut Allergy

RAMSES Phase 3 Safety Trial Was Consistent with PALISADE

Simulated real-world clinical practice and did not require a food challenge Replicated the PALISADE up-dosing period Like PALISADE, prophylactic anti-histamines, to mitigate allergic reactions, were not allowed ~80% of participants completed up-dosing and moved on to maintenance dose in both studies AR101 safety profile in RAMSES was consistent with that observed in PALISADE RAMSES Phase 3 Safety Trial of AR101 in Peanut-Allergic Children and Adolescents

PALISADE Demonstrated that AR101 Reduces the Frequency and Severity of Allergic Reactions to Peanut* *During the DBPCFC at study exit

Clinical Data Show Robust Efficacy and Safety of AR101 in Highly Sensitive Peanut-Allergic Children and Adolescents AR101 Efficacy at 12-Month DBPCFC in PALISADE1 AR101 Safety Profile in PALISADE1 and RAMSES Robust: Median tolerated dose increased 100-fold, up to ~3-4 peanuts (~6-8 peanuts, cumulatively) Reliable: 80% of AR101 participants completed the study, and nearly all tolerated the equivalent of ~ 1 peanut; 63% tolerated 1,000 mg (cumulative 2,043 mg) After desensitization, the exit food challenge results showed that AR101 reduced frequency and severity of allergic reactions to amounts of peanut protein typical of real-world accidental exposures Treatment-emergent adverse events (TEAEs) were common in both AR101 and placebo groups Vast majority of participants experienced mild/moderate symptoms in both trials TEAEs were lower in maintenance in PALISADE (no maintenance in RAMSES) Epinephrine use was infrequent and not a surrogate of anaphylaxis or symptom severity Low instances of anaphylaxis and EoE 1 Vickery et al., NEJM, November 18, 2018 (online publication)

Looking Forward

PALISADE Phase 3 Results Published in NEJM (Nov 18, 2018) “…treatment with AR101 resulted in higher doses of peanut protein that could be ingested without dose-limiting symptoms and in lower symptom severity during peanut exposure at the exit food challenge than placebo.” Vickery et al., NEJM, November 18, 2018 (online publication)

Aiming to Deliver on Our Promise to the Food Allergy Community Next year, AR101 could be the first approved treatment for peanut allergy Biologics License Application (BLA) for AR101 is on track for submission to the U.S. Food and Drug Administration (FDA) in December 2018 as planned; Marketing Authorisation Application (MAA) for Europe in mid-2019 also on track The recently announced investment of $98 million from Nestlé Health Science*, combined with our $255 million of cash as of the end of 3Q 2018, puts us in a great position to: Deliver AR101 to patients in the United States Continue to advance AR101 in Europe Develop our pipeline of treatments for other food allergies *Transaction expected to close in 2018
