HAMILTON, BERMUDA / ACCESSWIRE / May 16, 2023 / Altamira Therapeutics Ltd. (NASDAQ:CYTO) ("Altamira" or the "Company"), a company dedicated to addressing unmet medical needs, today provided a business update and reported its full year 2022 financial results ended December 31, 2022.

"We continue to make good progress on our journey to become a leading provider of innovative RNA delivery technology," stated Thomas Meyer, Altamira Therapeutics' founder, Chairman, and CEO. "Our OligoPhore / SemaPhore platforms are designed to address two major challenges in the development of RNA therapeutics. The first is delivery to tissues and organs other than the liver, for example for the treatment of cancers, autoimmune, or inflammatory disorders. The second is the effective and rapid release of the RNA payloads within target cells. We are excited to see interest in our technology growing steadily and, accordingly, we are confident we will enter into our first collaboration agreements this year with biopharmaceutical companies.

"At the same time, we are fast approaching important clinical and regulatory milestones with our legacy programs in OTC consumer health and in inner ear therapeutics," Mr. Meyer added. "This month, we expect to receive top-line data from the recently completed NASAR trial with Bentrio in seasonal allergic rhinitis. We just submitted an Investigational New Drug (IND) filing to the Food and Drug Administration (FDA) for AM-125 in acute vestibular syndrome on which we expect to receive comments or clearance in the weeks ahead.

"These milestones will be important elements in our strategy to divest or partner the legacy programs as the second step in our transformation to become a leading pure-play technology platform company in RNA delivery technology. Through this process, we expect to unlock the intrinsic value of our legacy businesses. While it has taken longer than initially expected, we look forward to major progress and its conclusion this year."

RNA Delivery Technology Update

Altamira has been making good progress with its strategic pivot to RNA delivery technology around its OligoPhore / SemaPhore platforms. The technology is based on a patented peptide for delivery of RNA in nanoparticles to extrahepatic tissues and efficient endosomal release inside target cells. It has been successfully tested in numerous animal disease models with both siRNA (short interfering RNA) and mRNA (messenger RNA). Recently, additional promising data were reported:

• At the 2023 Osteoarthritis Research Society International (OARSI) World Congress held in March in Denver, a Washington University research group presented data from a mouse model of meniscal injury. Systemic delivery of DNA-methyltransferase 3 beta (DNMT3B) mRNA with SemaPhore nanoparticles significantly reduced bone sclerosis, cartilage degeneration, and synovitis (inflammation of the connective tissue lining the inside of a joint capsule) compared to controls. In addition, functional studies showed significantly decreased pain sensitivity and improved weight bearing.
• In a March 2023 article preprint, another Washington University research group presented data from a mouse model of sarcoma and metastatic breast cancer. Systemic delivery of ZBTB46 (zinc finger and BTB domain containing 46) mRNA with SemaPhore nanoparticles promoted anti-tumor components in the tumor microenvironment and resulted in the restriction of tumor growth. When the nanoparticle treatment was combined with an anti-PD1 immune checkpoint inhibitor, significant synergistic effects in the control of tumor growth were observed, generating long-term complete remission of tumor mass in many of the treated animals.

Since 2022, Altamira has stepped up its efforts to present and promote its OligoPhore / SemaPhore platforms at international conferences and its business development activities targeted at potential partners in the biopharmaceutical industry. In general, consistent with its capital efficient RNA business model, the Company plans to focus on providing its nanoparticle technology to licensees rather than develop and commercialize its own drug products.

Concurrently, the Company continued the development work on its two ‘showcase' development programs with the OligoPhore platform for siRNA delivery - AM-401 for the treatment of KRAS-driven tumors and AM-411 for the treatment of rheumatoid arthritis (NF-kB). In February 2023, Altamira expanded its intellectual property estate by filing a provisional patent application relating to single polyvalent siRNA sequences which as part of AM-401 can target different KRAS mutations (polyKRAS^mut). If granted, the patent would extend IP coverage for the program to 2043. Altamira aims to advance both AM-401 and AM-411 to an IND filing with the FDA in 2024 and plans to out-license them either following the IND or after a Phase 1 clinical trial at the latest.

Bentrio® Nasal Spray

The clinical development program for Bentrio, the Company's novel drug-free nasal spray for protection against harmful airborne particles such as allergens, is nearly complete. In February 2023, data from three clinical studies were presented at the Annual Meeting of the American Academy of Allergy, Asthma & Immunology (AAAAI) in San Antonio, TX. In two randomized controlled crossover studies, Bentrio was shown to provide effective protection for patients in both seasonal and perennial allergic rhinitis under controlled exposure to grass pollen and house dust mites, respectively, for several hours. These positive outcomes were corroborated by a third study which demonstrated in healthy volunteers that Bentrio has a significantly longer nasal residence time within the nasal cavity and, compared to a classic saline nasal spray (3.5 hours vs. 1 hour), provides wider distribution and coverage therein.

The data read-out from the NASAR trial in Australia will complete the Altamira development program in allergic rhinitis. The study enrolled 100 patients suffering from seasonal allergic rhinitis who were treated for two weeks either with Bentrio or with a classic saline nasal spray as the current standard of care in drug-free treatments. In January 2023, the Company reported that an interim analysis based on the data from the first 53 NASAR participants showed a statistically significant reduction of nasal symptoms with Bentrio vs. the control as well as good tolerability and safety. The results from the complete trial are expected to become available in the month of May.

In contrast, the outcomes from the COVAMID trial with Bentrio in 160 patients suffering from acute COVID-19 which were reported in January 2023, were inconclusive under the specific test conditions. Although a trend for faster and more pronounced reduction in nasal viral load and symptoms was observed with Bentrio vs. the untreated controls, the differences were not deemed statistically significant. Altamira considers that the more benign outcomes from the Omicron variant resulted in more pronounced spontaneous recovery, and treatment may have started too late in the trial (about 4.5 days after infection). As previous studies with Bentrio on cultured human nasal epithelia cells exposed to various types of viruses had shown best results from prophylactic treatment application, the Company concluded that Bentrio is best used right before or while being exposed to virus particles. No further studies in viral infection are ongoing or planned.

As part of its strategic pivot to a pure-play RNA delivery technology company, Altamira initiated discussions last year with several well-established OTC consumer health companies for partnering on Bentrio for North America, Europe, and other key international markets. These discussions and related due diligence have extended into 2023 and are still ongoing at this point. In the context of these partnering discussions, the Company suspended preparations for launching the product in the US on its own and minimized marketing and sales activities in Europe. Meanwhile, the Company's existing distribution partners launched Bentrio in several Asian geographies, including Singapore, Malaysia, Indonesia, the Philippines, and Hong Kong.

Inner Ear Therapeutics

In June 2022, the Company announced positive top-line data from its Phase 2 TRAVERS trial with AM-125, a patented nasal spray formulation of betahistine for the treatment of acute vestibular syndrome (AVS). Detailed results were published in a peer-reviewed article in Otology & Neurotology, one of the leading journals in scientific and clinical inner ear research, in April 2023. AVS is characterized by the sudden onset of continuous vertigo lasting days to weeks and may be associated with nausea, head motion intolerance, and unstable balance. The randomized, double-blind, placebo-controlled TRAVERS trial enrolled a total of 124 patients, at more than 10 study sites across Europe, who suffered from AVS following surgery for the removal of a tumor. The trial demonstrated good tolerability of AM-125. Further, administration of AM-125 resulted in a dose- and time-dependent improvement in balance, and signs and symptoms of vestibular dysfunction.

Based on the positive outcomes from TRAVERS, the Company filed an IND application this past week with the FDA. The IND, if granted, would allow conducting clinical trials with AM-125 in the US as well. The submission includes the protocol for a Phase 2 trial in the treatment of posterior canal benign paroxysmal positional vertigo (BPPV), which is the most common type of vertigo and characterized by repeated episodes of vertigo produced by changes in the head position relative to gravity. A recently published meta-analysis shows statistically significant improvement in dizziness handicap for BPPV patients when treated with oral betahistine over the standard of care procedure alone. By avoiding the fast metabolism after oral intake, intranasal delivery of AM-125 achieves higher bioavailability of betahistine (5-to-29 times higher).

In the context of its strategic pivot to RNA delivery technology, Altamira intends to divest or partner the AM-125 program for further development and commercialization that includes the implementation of a Phase 2 clinical study. To this end, the Company has initiated discussions with a number of potential partners and expects to intensify such efforts following now that the IND has been submitted.
