Antibe Therapeutics Announces CEO Letter to Shareholders

TORONTO, ONTARIO – (April 26, 2018)

To our stakeholders,

The recent success of our lead drug, ATB-346, in its Phase 2B gastrointestinal (“GI”) safety clinical study was a significant milestone for Antibe and represented a major inflection point in our value. Furthermore, we are now one clinical study away from the strategic monetization of our drug platform for the major markets. With such an important and exciting time ahead of us, we thought this would be an ideal opportunity to communicate our strategy for the next year and beyond.

Nearly ten years ago, Antibe was formed to develop safer medicines for pain and inflammation by leveraging our novel hydrogen sulfide (“H2S”) technology. Over this period, our strategy to maximize value for shareholders has remained consistent: advance our drug candidates to Phase 2 proof-of-concept data and secure high-value partnerships for the large pharmaceutical markets. Fast forward to 2018: we now have unequivocal validation of our H2S platform, and are well-positioned to conclude a series of transformational partnerships over the next 12-18 months.

This progress could not have been done without the support of our shareholders, who are now being rewarded for their patience over the years. In the months ahead, our team will be working diligently to ensure that our clinical and business development activities are well aligned with our strategy to maximize shareholder return.

Recent Phase 2B Study Confirms Best-in-Class Status for Drug Platform

 In Antibe’s latest Phase 2B study, ATB-346 showed unequivocal superiority to naproxen in GI safety (2.5% versus 42.1% ulceration rate) in 244 healthy volunteers. This human proof-of-concept data replicated the results of our pre-clinical studies, and provides clear validation of the GI-protective properties of our H2S technology. The full analysis of this study will be reported this quarter. We are now pushing forward with the planned Phase 2 effectiveness study for ATB-346, and are accelerating development of our other H2S platform drugs. Each of Antibe’s drugs has blockbuster potential, and would provide physicians and consumers with radically safer alternatives to today’s NSAIDs and to the multi-dimensional dangers of corticosteroids and opiates.

Upcoming Phase 2 Effectiveness Study Designed to Validate Efficacy of ATB-346

With human GI safety for ATB-346 now firmly established, our next clinical objective is to validate its effectiveness at reducing pain in osteoarthritis (“OA”) patients. In August 2016, Antibe released top-line data from a Phase 2A study that showed considerable pain relief for ATB-346 at a once-daily dose of 250 mg – the pain relief observed was nearly double that of naproxen and Celebrex based on published data. Although these results were encouraging, the study was conducted in a small number of patients and was not controlled. Our upcoming Phase 2 effectiveness study is designed to validate the pain reduction efficacy of ATB-346 (versus control) and will be conducted in approximately 250 OA patients. In addition, we have biomarker data derived from Phase 1 and Phase 2 blood assays that suggest ATB-346 is effective at lower doses; for this reason, the study will include two additional dosing cohorts with the goal of determining the lowest effective dose. Preparations are well underway for this study and we anticipate commencing it by July with a data read-out in Q4 2018.

Additional Clinical Activities to Support Global Partnering Efforts

In addition to the Phase 2 effectiveness study, Antibe will also be strategically allocating R&D spend towards activities that we feel will be of the most value to global partners. These activities include: (i) long-range animal toxicology studies (6 months and 9 months) for ATB-346, a standard regulatory requirement for approval of any drug; (ii) additional metabolic studies for ATB-346 to further strengthen our understanding of its pharmacokinetic profile; and (iii) the completion of IND-enabling studies for both ATB-352 and ATB-340, Antibe’s two other H2S platform drugs. Although ATB-352 and ATB-340 are earlier stage, both individually represent blockbuster drug opportunities and have been considerably de-risked by the latest validation of our H2S technology. We remain particularly excited about the potential of ATB-352, a non-addictive, potent analgesic for acute pain that directly addresses the global opioid epidemic, a crisis that the world is struggling to contain.

 Partnering Discussions Building Momentum

In the past, Antibe’s partnering efforts were focused on strategically out-licensing the rights for smaller markets (i.e., outside of the United States and Western Europe). We continue to have these discussions and have been successful in concluding two regional deals to-date – this activity remains valuable as it provides non-dilutive funding and further validation of our drug platform. The recent human proof-of-concept GI safety data have undoubtedly benefited these on-going discussions, and more importantly, now allow us to engage multinational pharmaceutical firms to secure strategic partnerships for the large markets. As mentioned earlier, our clinical development activities in the next 12 months are designed to maximize the value of our drug platform and strengthen our position as we engage potential partners.

Commercial Asset in Regenerative Medicine Well-Positioned For Growth

Our subsidiary, Citagenix Inc. (“Citagenix”), is nearly done assembling the building blocks for its growth strategy in the dental regenerative medicine market. Citagenix’s sales team in the United States is working hard at expanding its distribution network, and recently signed Benco Dental, the 3rd largest dental distributor in the US by market share. Antibe’s relationship with Citagenix has been a symbiotic one: Antibe provided the resources to position Citagenix on a growth trajectory while Citagenix provided valuable diversification. With Citagenix now on a path to growth and Antibe’s drug development activities de-risked considerably by the recent GI safety data, our team will now begin exploring strategic alternatives for Citagenix in an effort to unlock value for shareholders.

Strong Balance Sheet and Maturing Capital Markets Strategy

Antibe’s balance sheet is well-funded with approximately $5 million of cash, and recently benefited from the entire conversion of its debentures. The upcoming Phase 2 effectiveness trial for ATB-346 will be funded entirely with cash-on-hand. In addition, given our stage of development, we are now exploring a listing on the NASDAQ exchange to grow our institutional investor base in the United States.

We look forward to the year ahead as we drive closer towards our goal of bringing safer medicines to market for pain and inflammation.

Sincerely,

Dan Legault

Chief Executive Officer
