BRISBANE, Calif.--(BUSINESS WIRE)--Aimmune Therapeutics, Inc. (Nasdaq:AIMT), a biopharmaceutical company developing CODIT™ (Characterized Oral Desensitization ImmunoTherapy) treatments for life-threatening food allergies, today announced that it has completed global enrollment of its Phase 3 PALISADE trial of AR101 for the treatment of peanut allergy, with the total randomized to the trial expected to be approximately 540 patients. AR101 is Aimmune’s investigational biologic oral immunotherapy for desensitization of patients with peanut allergy.
Aimmune continues to expect topline data from PALISADE in the fourth quarter of 2017, followed by regulatory submissions for marketing approval of AR101 in 2018 in both the United States and Europe. The company announced completion of North American enrollment in PALISADE in September, ahead of schedule and above target enrollment.
Aimmune also announced ARTEMIS (AR101 Trial in Europe Measuring oral Immunotherapy Success), a new dedicated European clinical trial of AR101 in peanut-allergic children and adolescents. ARTEMIS is designed to expand the data available on the efficacy profile of AR101 by exploring a higher level of protection after a shorter treatment period in a broader group of patients (in terms of baseline reaction) than in PALISADE. The primary efficacy endpoint in this new trial will be tolerating a cumulative amount of 2,043 mg of peanut protein in an exit double-blind, placebo-controlled food challenge (DBPCFC) after approximately nine months of treatment with AR101.
“PALISADE remains the cornerstone of our AR101 program, and the completion of global enrollment is a significant milestone. Now that the $145 million investment in Aimmune by Nestlé Health Science has closed, we have additional resources to further strengthen our development strategy,” said Aimmune CEO Stephen Dilly, M.B.B.S., Ph.D. “As previously announced, the RAMSES study, slated to begin in the United States in early 2017, is expected to provide important experience of AR101 in a ‘real-life’ clinical setting, building on our observation that removal of the baseline food challenge may meaningfully improve the tolerability of the early stages of AR101 treatment. We expect to file our biologics license application (BLA) on successful completion of PALISADE and RAMSES.
“With ARTEMIS, we are building on the observation that a very high proportion of patients in our ARC002 trial were desensitized to more than two grams of peanut protein at the nine-month endpoint. ARTEMIS is designed to confirm that finding in a double-blind, placebo-controlled setting,” said Dr. Dilly. “Demonstrating reliable, early desensitization with AR101 to such high levels would cement the utility of our low-dose, CODIT maintenance regimen. Furthermore, tolerating more than two grams of peanut protein would give patients an additional safety net in cases of accidental exposure, well after the threshold where they may taste peanut, which could offer greater reassurance and peace of mind. We expect to include the ARTEMIS results in our initial marketing authorization application in Europe.”
Sue Barrowcliffe, General Manager of Aimmune Europe, commented: “In Europe, we have seen great demand across multiple countries to be included in the global PALISADE trial, so we are very excited to conduct ARTEMIS as a dedicated European trial. It will offer a wider range of children and adolescents with peanut allergy the opportunity to participate in our clinical development program, and it will help to enhance our knowledge about the timing and extent of desensitization offered by AR101 treatment. As we have engaged with more stakeholders across Europe, we have also come to appreciate that confirming a higher efficacy reached sooner would be important in obtaining labeling for protection against accidental exposure and supporting reimbursement applications for AR101, especially as we see increased focus on cost effectiveness throughout Europe.”
ARTEMIS is a randomized, double-blind, placebo-controlled trial in peanut-allergic children and adolescents ages 4-17. The inclusion criteria for the trial will allow for baseline toleration of a cumulative amount not exceeding 144 mg of peanut protein in an entry DBPCFC (i.e., reacting at or before a cumulative amount of 444 mg of peanut protein, at the 300 mg dose of the challenge). Patients will undergo approximately six months of up-dosing and then three months of maintenance therapy at 300 mg of AR101 per day, followed by an exit DBPCFC. Aimmune expects ARTEMIS to enroll between 120 and 160 patients at multiple sites in Europe, beginning in mid-2017.
