Thank you, operator. Hello, everyone, and thank you for joining our first half of 2023 financial results and business update call.

Together with our Chief Operating Officer, Covadonga Paneda, I'm pleased to be providing an update on the advancements that we have made during the first half of this year, which includes updates on our clinical activities, recent strategic partnerships, positioning our legacy business for future opportunities, corporate developments that make us a stronger company today as well as our financials.

We will then address questions that we received from investors. For investors right now, macroeconomic uncertainty continues to prevail on a global scale. And also there is softening in many areas, labor, consumer demand, housing markets. I still believe in the resilience of our economy.

In the biotech sector, what we are seeing is a sense of renewed optimism. Many companies within our industry continue to make positive strides.

What's more, the future looks promising, thanks to exciting new discoveries and development making this an opportune time to strengthen product offerings and pipelines through strategic partnerships and acquisitions. We continue to make headway in our RNA therapeutics business this year.

This has been a process of repositioning the company that we initiated last year to generate long-term shareholder value. The evolution of our company includes leveraging our various pipeline assets which we have been very transparent and methodical about. RNA-based therapeutics represent a highly attractive and promising market.

In fact, live market research estimates that sales of RNA-based therapeutics based on RNA interference and anti-sense oligonucleotides are expected to reach $25.1 billion by 2030. Given that the corresponding figure for 2021 was just $4.9 billion, the industry is registering a compound annual growth rate of 17.6%.

And this is only one part of the market and opportunity as it does not even include any sales of mRNA therapeutics. RNA-based therapeutics hold vast promise for addressing numerous diseases that presently lack optimal or viable treatment options.

And thus, our focus in the long term is to hone in on tools for RNA delivery through therapeutic targets beyond the liver and efficient endosomal releases inside target cells.

With regards to our legacy assets centered on OTC consumer health and inner ear therapeutics, we have achieved significant milestones in the clinical and the regulatory domains. Notably, our clinical trial featuring Bentrio for seasonal allergic rhinitis successfully met its primary end point adding to the existing body of compelling efficacy data.

In addition, we were pleased to report that the FDA cleared an investigational new drug IND, our AM-125 drug, which targets acute vestibular syndrome. These milestones are important elements in our ongoing partnering discussions.

Our intent is to divest or partner our legacy assets Bentrio and AM-125 for further development and commercialization in the context of our strategic pivot to RNA delivery technology. To this end, our discussions are ongoing. I will provide you with updates as they become more concrete mature.

Concurrently, we achieved significant strides in elevating awareness and recognition of our OligoPhore/SemaPhore platforms, particularly in the realm of extrahepatic RNA delivery and efficient endosomal release.

We recently announced our collaboration with Heqet Therapeutics to pursue the development of cardiac regeneration treatments, harnessing the power of RNA through our OligoPhore platform.

This serves as an encouraging testament to the growing interest in our technology and we hold a strong conviction regarding the potential for forging additional partnerships with other biopharmaceutical companies. And now, I will pass the call over to our Chief Operating Officer, Covadonga Paneda, who will talk more about that and our RNA programs.

Cova?.

Thanks, Thomas, and good morning, everyone. Altamira's progress in advancing RNA delivery technology to our OligoPhore and SemaPhore platforms is meaningful. These platforms are built upon a patented peptide designed to deliver RNA nanoparticles to tissues beyond the liver and efficiently release them into target cells.

Recently, we received further external validation of this technology to two in vivo studies conducted by independent research teams at Washington University of Medicine in St. Louis. In one study, the research team shared annual data showing that nanoparticles based in our SemaPhore platform loaded with ZBTB46 mRNA efficiently restrained tumor growth.

What's more important is that the introduction of ZBTB46 mRNA specifically into the tumors of treated animals prompt the creation of an immune stimulating environment around the tumor further limiting its growth.

This effect was notably enhanced when combined with anti-PD-1 immune checkpoint inhibition therapy, indicating that ZBTB46 mRNA delivered by SemaPhore nanoparticles could serve as a valuable supplementary therapy alongside immunotherapy for cancer management.

This exciting development highlights the potential of our technology in the field of cancer treatment.

In the second study, researchers administered nanoparticles based on SemaPhore loaded with an mRNA encoding for DNMT3B, a protein known to be involved in cartilage on the [indiscernible] directly into the joints that is intraarticular administration of mice with meniscal injuries. The outcome was quite promising.

There was a robust increase in DNMT3B protein levels and the mice experienced significant reduction in bone sclerosis, cartilage degeneration and synovitis. In addition, the functional assessment revealed that the treated mice showed significantly decreased pain sensitivity and improved weight bearing in the active treated mice compared to controls.

The research serves as a testament of the potential of RNA therapy, and we couldn't be prouder of their achievements. These findings also bolster unwavering commitment to advancing RNA therapy and underscore the significant impact that it can have on improving health care outcomes.

Together with our partners and researchers, we remain steadfast in our mission to harness the power of RNA for the betterment of patients worldwide.

At the same time, we advanced the work on our two flagship development programs, AM-401 for the treatment of KRAS driven tumors, and AM-411 for the treatment of rheumatoid arthritis targeting NF-kB, aiming for an IND submission in 2024. We plan to out-license the two programs either following IND or after a Phase I clinical trial at the latest.

Importantly, we filed a provisional patent application related to the single polyvalent siRNA sequences, which as part of AM-401 and target different KRAS mutations. We call polyKRASmut. If granted, the patent would extent IP coverage for the programs to 2043.

In line with our strategy of leveraging OligoPhore/SemaPhore throughout licensing and partnering rather than commercializing our own products, we have significantly expanded our business development activity. This includes the engagement of Maria Grunwald, PhD, a highly experienced business developer based in Boston, as a Senior Business Advisor.

As Thomas mentioned earlier, on July 5, 2023, we announced that we were entering into a collaboration and option agreement with Heqet Therapeutics. A biotech spin-out from Kings College London.

For collaboration centers on the testing of nanoparticles utilizing our innovative OligoPhore delivery platform combined with specific non-coding RNA for the purpose of regenerating damaged heart tissue, post-myocardial infarction in animal models.

Should this experiments yield successful outcome, Heqet will have an option under certain conditions to initiate negotiations with Altamira for license, granting access to our technology and intellectual property. This in turn, would enable Heqet to advance their discoveries into department of therapeutics for cardiac regeneration.

The potential of cardiac muscle regeneration remains a topic of great interest to the global scientific and medical community, given the substantial complications and elevated mortality rates associated with myocardial infarction.

We firmly believe that Altamira's peptide-based OligoPhore platform tailored for RNA delivery possesses the capacity to serve as a secure and efficient conduit for controlled localized cardiac regeneration. In late May, we shared some exciting news about an article published in the International Journal of Molecular Sciences.

This paper titled peptide-based nanoparticles for systemic extrahepatic delivery of therapeutic nucleotide was offered by researchers from the University of Washington, St.

Louis; University of California, Los Angeles; and our very own Chief Scientific Advisor, Samuel Wickline, to discuss the challenges when trying to safely and efficiently deliver important RNA molecules to cells outside the liver. This RNA molecules have great potential for treating various diseases.

The difficulties lie in their natural instability and getting them inside cells. While there are some delivery methods that work well for liver-related conditions, they aren't as effective for other parts of the body.

Additionally, even when one manages to get RNA into cells, getting it out of the endosome and into the right part of the cell can be tricky. In recent years, science made tremendous strides in understanding how cells react to RNA treatment, but major challenges have remained for diseases that aren't liver-related.

That's where our peptide nanoparticles like OligoPhore and SemaPhore come into play. They offer a promising way to deliver RNA treatments to diseases beyond the liver and ensure they get where they are needed. I will now turn back the call to Thomas..

Thank you, Cova. Now let's discuss our legacy assets, the Bentrio drug-free nasal spray and our AM-125 betahistine nasal spray for vertigo. In the month of May, we shared exciting findings from the randomized controlled NASAR clinical trial, evaluating Bentrio nasal spray in patients with seasonal allergic rhinitis, short SAR.

To study the efficacy of Bentrio, there's a NASAR trial enrolled 100 patients in Australia, who were randomized at a 1:1 ratio to receive either Bentrio or saline nasal spray for two weeks via self-administration 3 times per day or as needed.

For eligibility, patients had to have a baseline reflective total nasal symptom score, rTNSS of at least 5 points out of 12, referring to the worst level of nasal congestion, sneezing, nasal itching and rhinorrhea, which is runny nose, within the past 24 hours averaged over a one-week treatment-free run-in period.

The primary efficacy endpoint was defined as the difference in the average rTNSS over the subsequent two-week treatment period between Bentrio and saline nasal spray, which is the current standard of care when it comes to drug-free allergic rhinitis management.

The NASAR results demonstrated for Bentrio a statistically significant and highly relevant clinical improvement in efficacy over saline nasal spray. The improvement from baseline was 1.9 points in the rTNSS, which was 1.1 points or 2.4 fold larger than saline. Both outcomes came in well above the minimal clinically important difference of 0.28 points.

63% of Bentrio-treated study participants rate treatment efficacy is very good or good compared to just 29% of saline spray users.

Whereas a saline nasal spray aims to rinse-out allergen articles, Bentrio forms a thin protective layer, which prevents contact of those particles with the nasal mucosa and helps to remove them through natural mucociliary clearance.

As already demonstrated in a previous trial, Bentrio stays for about 3.5 hours within the nasal cavity where it can exert its protective effects. In contrast, saline sprays present for only about 1 hour and provides narrow distribution and less coverage within the cavity.

We expect to release further results from the NASAR trial shortly and to submit an article for publication in a peer-reviewed medical journal. The data readout from the NASAR trial completes the Bentrio development program in allergic rhinitis.

Previous clinical trials demonstrated already safety, tolerability and the efficacy of Bentrio in patients exposed to grass pollen or house dust mites under controlled conditions and the extended nasal residence time of more than 3 hours in human volunteers.

The accumulated data suggests that Bentrio based on a drug-free and preservative-free formulation can help to effectively reduce the most common symptoms of allergic rhinitis.

The reduction of symptoms was similar to that observed in response to medicated nasal sprays, but without the tolerability issues, frequently experienced with the use of such sprays. In July, we announced an exclusive agreement with Pharma Nordic for the marketing and distribution of Bentrio in Norway and potentially for the Scandinavian countries.

The collaboration agreement will allow Pharma Nordic to market and commercialize Bentrio in Norway, beginning in the first quarter of 2024 and subject to meeting certain milestones also in Sweden, Finland and Denmark later on.

We look forward to building Bentrio together with Pharma Nordic into one of the leading brands for allergic rhinitis management in Scandinavia. Discussions with potential marketing and distribution partners for the U.S. and other key markets have continued to move forward and are still ongoing at this time.

In the context of these partnering discussions, we have made the decision to suspend preparations for launching Bentrio in the U.S. on its own and minimize marketing and sales activities in Europe, as previously communicated. It's worth noting that in 2023, the U.S.

sales of over the counter allergy remedies are estimated to reach close to $4 billion, representing a major opportunity in a non-medicated preservative-free treatment category.

Together with our marketing and distribution partners, we are looking forward to making Bentrio available as an effective and safe treatment option to help patients deal with the daily burden and this comfort associated with allergic rhinitis.

With regards to our AM-125, on June 29, following a review of our IND application for AM-125 received from the FDA a study may proceed later.

The IND clearance means that the proposed Phase II clinical trial was AM-125 in the treatment of benign paroxysmal positional vertigo, BPPV, which is the most common form of vertigo has been authorized and may be conducted in the U.S. This has been a major step in our development program.

An earlier Phase II clinical trial conducted in Europe, the TRAVERS trial demonstrated that a four week treatment course with AM-125 in vertigo patients following surgical removal of a tumor behind the inner ear was well tolerated and helped to accelerate vestibular compensation, enabling patients to regain balance and recover faster.

The new Phase II trial is designed to demonstrate AM-125's tolerability in clinical utility also in BPPV. As previously announced, we intend to divest or partner the AM-125 program for further development and commercialization in the context of our strategic pivot to RNA delivery.

To this end, we have initiated discussions with a number of potential partners based on a structured approach. It is probably worth mentioning that vertigo balance problems are among the most frequent and increasing health issues in the general population.

In 2016, 36.8 million adults or 15.5% reported a balance problem in the past year compared to 24.2 million or 11.1% in 2008. Betahistine, the active substance of AM-125 is a standard of care treatment in oral form for vertigo in dozens of countries worldwide, but it's not marketed in the U.S.

We believe that AM-125, which offers much better bioavailability than betahistine tablets with great potential, both in existing betahistine markets, but in particular also in the U.S. Turning next to our financial highlights for the first half of 2023.

Revenues for the first half of 2023 were CHF0.1 million compared to CHF0.3 million for the first half of 2022, reflecting the waning of SARS-CoV-2 infections and more importantly, the aforementioned strategic decision to temporarily reduce commercial activities around Bentrio in anticipation of a partnering transaction for key markets.

Total operating loss for the first six months of 2023 was CHF4.6 million compared with CHF8.4 million for the first six months of 2022, a reduction of 45.5%. The improvement was primarily driven by lower expenditures for research and development as clinical trials went down and for marketing and sales as commercial activities were reduced.

General and administrative expenses slightly increased in the first half of 2023 as higher costs related to capital market projects outweighed reductions in admin expenditures. The net loss for the first half of 2023 was CHF5.4 million compared with CHF8.2 million for the first half of 2022.

Financial liabilities decreased from CHF5.9 million at the end of 2022 to CHF3.1 million at June 30. Shareholders' equity improved at the same time from a deficit of CHF8.3 million to a deficit of CHF1.8 million. Cash and cash equivalents on June 30, 2023, totaled CHF50,000 compared with CHF15,000 at December 31, 2022.

In early July '23, we raised $5 million in equity through the public offering of 11.1 million common shares or prefunded warrants at $0.45 each and the same number of warrants with an exercise price of CHF0.4 on a five year duration. The transaction yielded net proceeds of CHF3.7 million.

As a result, we expect total cash need in 2023 to be in the range of CHF12 million to CHF14 million, and in the 12 months from the issuance date of our most recent financial statements here to be in the range of CHF12 million to CHF14 million. I would now like to turn to answering the questions that were submitted to us for today..

The first question is about our betahistine program. Who are the competitors? Why do you think AM-125 is going to be a success in the U.S. market? The competitive landscape is different between the U.S. and the rest of the world, when it comes to the dizziness treatments.

In the U.S., dizziness or vertigo today is treated primarily with vestibular depressants like meclizine or benzodiazepines, which are generic drugs. They typically sedate patients to deal with immediate symptoms like nausea or vomiting.

However, they should not be taken for more than three days since they tend to suppress vestibular compensation and healing. These drugs are also known in the rest of the world, but one important difference that is there oral betahistine is available as another treatment option.

Actually, this is considered the standard of care in most of these markets. Annual sales of oral betahistine are currently about $450 million. Unlike the vestibular suppressants, betahistine does not sedate patients. It actually increases alertness and enhances vestibular compensation.

There are two major players today in the oral betahistine market, which are a Viatris in Europe, Canada and Australia and Abbott (ph) in probably more than 100 countries around the world. With AM-125, we have a formulation for intranasal application, which has a much higher bioavailability than oral betahistine as mentioned.

Based on this, we expect AM-125 to help grow the market and to take share from oral betahistine in the rest of the world.

Now for the U.S., we see the lack of oral betahistine as a great opportunity since doctors, neurologists, ENT physicians and others, they clearly see the need for non-sedating vertigo treatments that support vestibular compensation rather than suppress it.

It's very unusual that a drug that is so frequently used worldwide is not on the market in the U.S. We expect the AM-125 to fill this important gap in the U.S. market. The next questions are about RNA activities, and they will be answered by Dr. Paneda.

The first one is, if your platforms are truly exceptional, how come that you still need to make a lot of efforts to make it known? Cova, please..

The field of RNA therapeutics in constant evolution and drug and biotech companies are continuously assessing different technologies to ascertain the best option to deliver their RNA-based drugs.

Up to now, the field has been extremely focused on lipid nanoparticles or as they are known, LNP and for good reason, the progress achieved with LNP has been spectacular. The technology is very powerful.

However, this technology has also limitations, especially when it comes to delivering RNA to target tissues beyond the liver and regarding the release of the RNA cargo within target cells. Given the good performance for liver delivery, a lot of efforts have been made to modify LNPs in a way that they reach also elusive non-hepatic tissue.

Success has been rather limited so far. And in addition, there are quite a few intellectual property issues that come with this technology. Therefore, pharma and biotech companies have started to explore alternatives.

I think that we've made great efforts and progress within a relative short period of time to increase the visibility of our technology with them, and especially also beyond scientific circles. We are very pleased that we have been invited to more and more industry symposia conferences to present our technology.

The most recent example is our participation in the RNA therapeutics and delivery conference in Berlin, where we are moderating a panel on the future of RNA therapeutics outside the liver and sharing a session on RNA formulation strategy.

In parallel to increasing our visibility, we have been engaging in a growing number of business development discussions with biotech and pharma company. So these discussions, we can draw on and show potential partners a large and growing amount of data. The Heqet collaboration has been just the start.

Based on our growing pipeline of leads, we expect to enter into more collaboration as we move forward..

Okay. Thank you. And the second question to you is the following.

How and well will you start making money on the RNA business?.

There are two main paths for RNA business generating money. The first is through collaboration with companies that seek to use our technology to deliver their RNA cargo and milestones coupled with these deals. So this is about granting access to OligoPhore and SemaPhore platform. Longer term, this will be the key driver for us.

The second is through out-licensing our two flagship programs AM-401 and AM-411. Here, as I already mentioned, we expect to partner them either after filing an IND next year or after Phase I. Typically, such transactions include some upfront payments, milestones as well as royalties..

Okay. Thank you, Cova. The next and final question is about our Bentrio program. There are quite many nasal sprays available for treating hay fevers. Since you want to partner Bentrio.

The obvious question is, what could be the appeal of such a product to one of those larger OTC companies? Well, it's certainly true that there are quite a few offerings out there for sufferers of allergic rhinitis. Importantly, there is no cure for it except for desensitization, which is allergen-specific immunotherapy.

Most sufferers seek to manage the symptoms by either trying to prevent or reduce exposure to allergens or by seeking to relieve them. Frequently, antihistamines are used either in the form of tablets or nasal sprays. They block or reduce the action of histamines, which the body releases when under attack from allergens.

Now another drug-based option is the use of corticosteroid sprays which seek to reduce the inflammatory response. And then their seawater saline nasal sprays, which helped to rinse the nasal cavity and eliminate allergens. This is a very popular drug-free option.

Now as always, there is some kind of trade-off involved with any of these treatment options. Some of the drug-based treatments, especially older antihistamines can make you feel drowsy.

Then drug-based treatments usually contain some preservatives, which may provoke some sting or burning sensation and may dry-out your nasal mucosa, a well moisturized nasal mucosa is very important for the natural line of defense of the nose.

And then while these drugs sometimes may take a while to start acting, which may be an issue, for example, if you unexpectedly get exposed to allergens and would like to protect yourself ASAP. On the other hand, the saline nasal sprays are usually well tolerated as they are physiological. So they top the drug-based options on that account.

However, the trade-off is that their efficacy is lower. This is rinsing. And so you have this seawater drain off relatively quickly, and you will need to reapply frequently, which is not that practical. Now for Bentrio, we are seeing an attractive positioning allowing for significant product differentiation.

So Bentrio has a triple mode of action, rapid onset and several hours of nasal residence time. So it’s efficacy is approaching that of Medicaid nasal sprays, yet its safety and tolerability similar to seawater nasal sprays.

So in short, we consider that Bentrio is an attractive product for management of allergic rhinitis, offering strong clinically relevant efficacy, rapid onset and favorable tolerability and safety profile.

We believe this is quite compelling, and we are happy to have received patient feedback supporting this, both in the context of our clinical trials and also from patient testimonials. So this is the end of the Q&A session. So these have been good questions. I hope we could answer them well.

I believe we've covered all the highlights thoroughly today, so I will simply thank everyone for attending this morning's call and we'll wish you a terrific day ahead. Thank you very much..

This concludes today's conference and you may disconnect your lines at this time. Thank you for your participation..
