BRISBANE, CA, USA I December 19, 2018 I Aimmune Therapeutics, Inc. (Nasdaq: AIMT), a biopharmaceutical company developing treatments for potentially life-threatening food allergies, today announced that it has initiated POSEIDON (Peanut Oral Immunotherapy Study of Early Intervention for Desensitization), an international, Phase 3 clinical trial of AR101 in peanut-allergic children ages 1–3 years. AR101 is Aimmune’s investigational biologic oral immunotherapy for desensitization of patients with peanut allergy.
“Following the success of our landmark PALISADE trial, we are building on our robust safety database of more than 1,000 AR101-treated patients, and are excited to start this important study of AR101 to examine the potential treatment benefit for younger children who need a path to protection that matters,” said Daniel Adelman, M.D., Chief Medical Officer of Aimmune Therapeutics. “We intend to submit regulatory filings for marketing approval of AR101 in the United States and Europe in 4–17-year-olds based on the positive data from the PALISADE clinical trial, which met its primary and key secondary endpoints, as well as data from additional ongoing and completed AR101 clinical trials.”
The primary efficacy endpoint for POSEIDON is tolerating a 600-mg single dose of peanut protein (the equivalent of approximately two peanut kernels) with no more than mild symptoms in a progressive, exit, double-blind, placebo-controlled food challenge (DBPCFC) after approximately one year of treatment.
“Food allergies are a growing, potentially life-threatening condition with no approved treatments, and peanut allergy, which is often diagnosed in the first or second year of life, is one of the most common food allergies, affecting more than six million people in the United States and Europe,” said Brian Vickery, M.D., Associate Professor of Pediatrics at Emory University and Founding Director of the Food Allergy Center at Children’s Healthcare of Atlanta, member of the Aimmune Scientific Advisory Board, and Principal Investigator for the POSEIDON trial. “This trial represents the critical next step not only in validating that early immunotherapy in young peanut-allergic children is safe and highly effective, but in generating evidence that, pending approval, AR101 can be smoothly incorporated into allergists’ practices to address the needs of children who can benefit.”
POSEIDON (Peanut Oral Immunotherapy Study of Early Intervention for Desensitization, clinicaltrials.gov number NCT03736447) is an international, randomized (2:1), double-blind, placebo-controlled Phase 3 trial to evaluate the efficacy and safety of AR101 in peanut-allergic children ages 1–3 in five countries in North America and Europe. Enrollment will be based on stringent entry criteria, including a documented clinical history of peanut allergy, positive skin prick tests and/or elevated blood levels of peanut antibodies, and a double-blind, placebo-controlled food challenge (DBPCFC). In POSEIDON, patients will undergo a dose escalation period of approximately 22 weeks to reach a dose of 300 mg per day of AR101 or placebo, then continue on that dose for approximately six months. During treatment, the trial will allow treating physicians to use prophylactic antihistamines at their discretion as is customary in clinical practice. At the end of the trial, patients will undergo an exit DBPCFC.
