Frostbite

Assets include the FDA-approved LIKMEZ™, the ATI-1701 tularemia vaccine defense program that has been awarded a USD $14 million non-dilutive award from the DoD, and the ATI-1801 topical formulation MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)-- Aditxt, Inc. (“Aditxt” or the “Company”) (NASDAQ: ADTX), a company dedicated to discovering, developing, and deploying promising health innovations, today announced that it has entered into a definitive arrangement agreement ("Arrangement Agreement") to acquire Appili Therapeutics Inc. (TSX: APLI; OTCQX: APLIF) (“Appili”), a biopharmaceutical company focused on drug development for infectious diseases and medical countermeasures. Under the Arrangement Agreement, Aditxt’s wholly owned subsidiary, Adivir, Inc. (“Adivir”) agreed to acquire all issued and outstanding Class A common shares of Appili (the “Appili Shares”) through a court-approved plan of arrangement under the Canada Business Corporations Act ("Transaction"). Since its inception in 2015, Appili has developed a diverse portfolio, including the FDA-approved LIKMEZ™ (previously ATI-1501), ATI-1701 biodefense program supported by a USD $14 million non-dilutive award from the U.S DoD., and ATI-1801, a topical formulation targeting cutaneous leishmaniasis, a painful and disfiguring disease. LIKMEZ, FDA-Approved Taste-Masked Oral Suspension for Bacterial Infections Appili developed LIKMEZ, a new formulation of the antibiotic metronidazole, specifically tailored to improve patient experience and adherence, particularly in patients who have difficulty swallowing large tablets. The patent-protected LIKMEZ is a reformulated taste-masking technology containing metronidazole, which makes it easier to swallow and better tasting, increasing patient compliance. The U.S. FDA's approval of LIKMEZ highlighted Appili’s capacity to identify and develop significant opportunities within the infectious disease domain. Appili licensed the manufacturing and commercialization rights in the U.S. and other selected territories to Saptalis Pharmaceuticals, LLC (“Saptalis”). Appili, in collaboration with Saptalis, continued the product's development, ultimately achieving FDA approval in the United States. With FDA approval, future revenue is expected to be derived from milestone payments and royalties from Saptalis under the license agreement. ATI-1701, Live Attenuated Vaccine for Francisella Tularensis Appili is developing ATI-1701 as a live attenuated vaccine to combat Francisella tularensis, which is classified by the U.S. National Institutes of Health (NIH) as a Category A pathogen, an organism that poses the highest risk to national security and public health due to its high rate of infectivity and ability to cause lethal pneumonia and systemic infection. Estimated to be 1,000-fold more infectious than anthrax, experts consider the aerosolized form to have a high potential for use in a bioterrorism attack. Appili's strategic alignment with governmental and public health priorities has secured non-dilutive funding of USD $14 million from the U.S. DoD for its ATI-1701 biodefense program. This funding has been crucial in advancing the development of ATI-1701, including support for manufacturing, non-clinical studies, and regulatory activities through the submission of an Investigational New Drug (IND) application. ATI-1701 may be eligible for a Priority Review Voucher (PRV) if the U.S. Government extends the Medical Countermeasures PRV program. A PRV enables its recipient to expedite the review process for future drug applications upon issuance. While no assurance can be provided that ATI-1701 will be deemed eligible for a priority review voucher or, what its ultimate worth will be if approved, and recent secondary market transactions involving PRVs have ranged from USD $80 million to USD $100 million, their strategic value extends beyond the secondary market, offering significant advantages in accelerating the development timeline of new treatments. ATI-1801, Topical Formulation for the Treatment of Cutaneous Leishmaniasis (CL) ATI-1801 represents Appili’s innovative approach to combating cutaneous leishmaniasis (CL), a devastating skin infection classified by the World Health Organization (WHO) as a Neglected Tropical Disease (NTD) that impacts hundreds of thousands of individuals globally. This topical product is formulated with paromomycin, a previously approved antibiotic available in oral or injectable form. The topical formulation allows a more direct and comfortable application for patients who suffer from painful CL lesions. Having undergone evaluation in a Phase 3 study, ATI-1801 targets CL infections that manifest through skin lesions and ulcers, leading to potential scarring, disfigurement, and societal stigma. Appili is committed to collaborating with stakeholders worldwide to advance the development of ATI-1801 and to obtain regulatory approvals, ensuring global access to this critical treatment. Additionally, Appili is assessing the potential for ATI-1801 to qualify for a Priority Review Voucher (PRV), a step that could further expedite bringing this essential therapy to those in need. Synergy with Aditxt’s Programs This acquisition will enhance Aditxt’s portfolio of subsidiaries and create synergies with its existing programs, particularly precision diagnostics. Integrating Appili’s expertise and product lines would pave the way for a comprehensive approach to population health, from early detection and prevention to treatment. The potential for collaboration within the Aditxt ecosystem can streamline patient care, from early detection through precision diagnostics to developing tailored treatment strategies. Amro Albanna, Co-Founder, Chairman, and CEO of Aditxt, elaborated on the significance of this acquisition, stating, “The acquisition of Appili would represent another step in Aditxt’s journey towards advancing promising innovations in health. Our mission is to accelerate some of the most promising health innovations, like those developed by Appili, to reach their full potential and to have a lasting impact. The urgency for innovative and effective public health solutions is unprecedented. The need to discover and bring new treatments to the market or to enhance existing ones to combat public health challenges has never been more critical. By integrating Appili’s proven expertise and diverse portfolio in the infectious disease and biodefense domain, Aditxt can substantially contribute to advancing public health solutions.” “This transaction with Aditxt aligns with our goals on multiple levels. We see this as an opportunity for growth, innovation, and collaboration. Our shared vision and combined expertise will undoubtedly accelerate our mission to develop innovative treatments and solutions for some of the most challenging health threats facing the world today. Appili can now leverage Aditxt’s proven research and development, operations, and commercialization expertise to accelerate the development of our three programs. Secondly, as a NASDAQ-listed company, we believe Aditxt can facilitate capital access in this challenging economic environment. We welcome this new chapter, confident that together, we will achieve even greater heights in deploying innovative healthcare solutions,” said Dr. Don Cilla, President and CEO of Appili Therapeutics.

The FDA approved Eicos Sciences’ injectable vasodilator Aurlumyn (iloprost) for the treatment of severe frostbite in adults, making it the first drug to be authorised in this indication.“Having this new option provides physicians with a tool that will help prevent the life changing amputation of one’s frostbitten fingers or toes,” remarked Norman Stockbridge, director of the Division of Cardiology and Nephrology in the FDA’s Center for Drug Evaluation and Research. The approval was supported by findings from a study involving 47 adults with severe frostbite, all having received intravenous aspirin and standard care. Participants were randomly assigned to receive Aurlumyn alone, or other medications that are unapproved for frostbite either alone or in combination with Eicos’ drug. The primary endpoint was a bone scan performed seven days after the onset of frostbite, with the goal of establishing the need for amputation of at least one finger or toe.At day seven, none of the patients given Aurlumyn alone had a bone scan indication for amputation, compared with 19% in those administered Eicos’ drug in combination with other medicines and 60% in the third group. In addition, the Aurlumyn groups had significantly fewer patients with bone scan abnormalities, and the majority of patients’ subsequent amputation status at follow-up was consistent with the bone scan findings. The FDA noted that Aurlumyn’s label carries a warning and precaution highlighting a risk of symptomatic hypotension. Iloprost gained its first FDA approval back in 2004 as an inhaled therapy for the treatment of pulmonary arterial hypertension under the brand Ventavis. Eicos, a subsidiary of CiVi Biopharma, has reformulated the drug into an intravenous form and is also investigating it for systemic sclerosis and as an anticoagulant in patients receiving extracorporeal membrane oxygenation.

The US Food and Drug Administration (FDA) has approved Eicos Sciences’s Aurlumyn (iloprost) injection, a new treatment for adults with severe frostbite to lower the risk of amputation of fingers or toes. Aurlumyn contains iloprost, a vasodilator that opens blood vessels and stops blood clotting, as its active ingredient. The efficacy of iloprost in treating severe frostbite was established through an open-label controlled trial in 47 adult subjects. Participants were randomised into three groups, with group one receiving iloprost intravenously for six hours daily for up to eight days along with aspirin and standard of care. Groups two and three were administered other medications, with and without iloprost, which are not approved for frostbite treatment.

The scans showed that none of the subjects who received iloprost alone (group one) required amputation compared to 19% in group two and 60% in group three. This indicated a significant reduction in the presence of bone scan abnormalities in groups receiving iloprost. Most subjects had follow-up data available to confirm whether they underwent amputation. This aligned with the bone scan findings. Headache, flushing, heart palpitations, nausea and hypotension were common side effects linked to Aurlumyn treatment. The treatment carries a warning for potential symptomatic hypotension. Aurlumyn was granted priority review and orphan drug designations for this indication, highlighting its significance in addressing severe frostbite, a condition that can escalate from mild to severe, potentially leading to permanent tissue damage and the cessation of blood flow. Iloprost originally received approval in 2004 for pulmonary arterial hypertension. FDA Center for Drug Evaluation and Research Division of Cardiology and Nephrology director Norman Stockbridge stated: “This approval provides patients with the first-ever treatment option for severe frostbite. “Having this new option provides physicians with a tool that will help prevent the life-changing amputation of one’s frostbitten fingers or toes.”
