INI-2004

MISSOULA, Mont., May 15, 2024 /PRNewswire/ -- Inimmune, a leading clinical stage biotech company focused on the development of novel vaccine adjuvants, immunotherapies and delivery systems, announced today the top line results from its Phase 1b Multiple Ascending Dose (MAD) study of INI-2004 in people suffering with Allergic Rhinitis (NCT06038279). In response to ragweed challenge, participants treated with INI-2004 showed a dose dependent improvement in nasal congestion as measured by acoustic rhinometry compared to placebo participants. Participants treated with INI-2004 exhibited a dose dependent trend towards higher cytokine biomarkers from nasal swab samples compared to placebo. Additionally, all doses of INI-2004 were well tolerated over multiple administrations and no MTD was reached. This follows Inimmune's successful completion of its Phase 1a Single Ascending Dose (SAD) study of INI-2004 in healthy volunteers. Using a randomized, placebo-controlled, double-blind study design (n=35), INI-2004, a synthetic Toll Like Receptor (TLR) 4 agonist in a mucosal formulation, was delivered intranasally to participants with ragweed allergy. INI-2004 was well tolerated. The adverse events (AEs) were mostly mild in severity, transient, and occurred at a similar rate across INI-2004 and placebo groups. Although this Phase 1b safety study was not powered to measure efficacy, a difference was observed in measured nasal volume between groups. For eligibility, participants were initially dosed with ragweed allergen to produce a 30% decrease in nasal volume, a measure of nasal congestion, as determined by acoustic rhinometry. Eligible participants then received four weekly intranasal administrations of 125, 250, or 500 µg INI-2004 or placebo followed by ragweed challenge after the second and fourth administrations. Acoustic rhinometry was completed multiple times over the course of the study. Participants who received 250 µg and 500 µg doses of INI-2004 had, on average, 34% and 53% improvement, respectively, in nasal volume post ragweed challenge compared to placebo. Inimmune's CEO, Alan Joslyn, said "We are pleased to see that INI-2004 was very well tolerated at all dose levels and after multiple treatments. It's also exciting that INI-2004 showed an early objective efficacy signal in improved congestion for these allergy sufferers relative to placebo despite the small number of participants evaluated. We look forward to demonstrating more symptom-focused measures of efficacy in an upcoming allergen challenge chamber study in patients with moderate to severe ragweed allergy." About INI-2004: INI-2004 is an allergen-agnostic immunotherapy that binds and activates Toll-Like Receptor 4. When delivered intranasally, INI-2004 dramatically reduced measures of allergic rhinitis (AR) in pre-clinical animal models. These include airway resistance, eosinophil influx, and the production of cytokines involved in the pathogenesis of AR. Demonstration of safety and efficacy in people will lead to a first-in-class, disease-modifying treatment for AR that may be used for a wide range of allergens, potentially changing how AR and allergic conditions are treated worldwide.

(Missoula, MT) is a privately held clinical stage biotechnology company focused on the discovery and development of innovative immunotherapeutics, vaccine adjuvants and vaccines.

Milestone marks transition of Inimmune Corporation to a clinical-stage company MISSOULA, Mont., Aug. 2, 2023 /PRNewswire/ -- Inimmune Corporation ("Inimmune"), a clinical-stage company focused on the development of innovative immunotherapeutics, today announced that the first subject has been dosed in Inimmune's phase 1/1b First-in-Human clinical trial of INI-2004, Inimmune's TLR4 agonist product candidate under development as a potential treatment of allergic rhinitis. The phase 1/1b trial is a randomized, double-blind, placebo-controlled, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of INI-2004 in healthy volunteers and participants with allergic rhinitis (AR). The phase 1 trial is a single ascending dose (SAD) study with up to 4 cohorts, and healthy volunteers are to be randomized 3:1 to receive a single intranasal dose of INI-2004 or placebo. This portion of the study is being conducted in Australia under Therapeutic Goods Administration (TGA) authority and Human Research Ethics Committee (HREC) oversight. "Australia is the ideal location for us to conduct a cost-effective, high-quality phase 1 study," said Jon Ruckle, MD, CMO. "We already have in place an Australian subsidiary, an experienced phase 1 clinical site, and a relationship with a well-respected local contract research organization." Inimmune also announced that it has received clearance of its Investigational New Drug (IND) application from the U.S. Food and Drug Administration (FDA) to initiate the phase 1b portion of the trial in the U.S. The phase 1b portion of the trial is a multiple ascending dose (MAD) study with up to 3 cohorts where subjects with seasonal allergic rhinitis are to be randomized 3:1 to receive multiple intranasal doses of INI-2004 or placebo. Thomas Casale, MD, Director, Division of Allergy and Immunology Joy McCann Culverhouse Clinical Research Center, University of South Florida said "Despite the availability of many different therapies for the treatment of allergic rhinitis, a large proportion of the 20 to 30% of the US population suffering from allergic rhinitis still has significant symptoms and impaired quality of life. INI-2004 has the potential to provide a novel treatment that addresses the underlying immunologic mechanisms responsible for allergic inflammation and symptoms, thereby addressing a significant medical need." "We are thrilled to have accomplished these momentous milestones. These are important milestones for our company, representing our first program to receive FDA clearance to enter the clinic and our first dosing in a FIH clinical trial, demonstrating our drug discovery and clinical development capabilities," said Alan Joslyn, Ph.D., Inimmune's CEO. "INI-2004 leverages our groundbreaking science as it was designed to be allergen-agnostic and can potentially be an effective treatment for multiple allergic diseases."
