RELIEF THERAPEUTICS : announces termination of the agreements with Genclis and H&H Group

Geneva, Switzerland, 2 August 2019

RELIEF THERAPEUTICS Holding SA ('Relief', 'the Company') announces that it has terminated two collaboration and (sub)licensing agreements signed in 2018. Relief will no longer take part in the collaboration to develop and commercialize products derived from whey and/or milk and have the potential to prevent allergies. The Company has withdrawn from both the agreements with the privately-held French company Genclis SA (Genclis) focusing on the development and commercialization of human applications of artificial colostrum and cow milk for the prevention of allergies and the agreement signed with Genclis and Health and Happiness (H&H) Hong Kong Limited (H&H Group) for the development of cow milk for allergy prevention.

Although the collaboration between Genclis, H&H and Relief has been quite successful thus far, with lab scales results already in line with Genclis fundamental research and opening very solid prospects for the future technology scale up, Relief will no longer take part in these efforts.

While the potential of Genclis technology and the resulting products remains highly valued by Relief, this decision by the Company's Board of Directors eliminates all of its existing financial liabilities toward Genclis in the context of the agreement, thereby protecting its liquidity situation.

Raghuram Selvaraju, Chairman of the Board of Directors of Relief concludes by saying: 'The decision to leave this collaboration was driven by the need to protect our short-term cash flow. We are still highly supportive of the revolutionary innovation of Genclis and the collaboration with H&H that will hopefully allow them to deliver new products to the market.

Patrice Malard, Chief Technology Officer of H&H declared: 'The collaboration with Relief has been very productive. We remain committed to developing a commercially viable alternative to the hypoallergenic milks currently on the market based on the groundbreaking technology of Genclis.'

Bernard Bihain, Chairman and Chief Executive Officer of Genclis, added: 'Collaborating with H&H remains one of our priorities to provide high-quality products to allergic patients. Relief brought significant expertise in these endeavors, and Genclis will continue its efforts to build on the foundation that we have established together.'

Mr. Selvaraju concluded by saying: 'We wish both H&H and Genclis all the best for their current development efforts and hope to join with them to pursue new potential opportunities in the near future.'

About Relief Therapeutics Holding SA

RELIEF THERAPEUTICS Holding AG is a clinical-stage biotechnology company with a portfolio of drug candidates derived from natural human origins. Its two first candidates are Aviptadil for the treatment of sarcoidosis (to enter Phase III) and low dose interleukin-6 (Atexakin alfa) for the treatment of peripheral neuropathy (to enter Phase II). Aviptadil development in sarcoidosis addresses the orphan disease market, in which European regulators have indicated that a single pivotal Phase III trial would be sufficient to support approval. Atexakin alfa is the subject of an exclusive worldwide development and commercialization agreement with Merck KGaA, The current priority indication for Atexakin is to alleviate peripheral diabetic neuropathy, a market that is estimated to reach $4.1 billion in 2019 (source: Datamonitor). In addition to these initial drug candidates, Relief has initiated a strategic collaboration with Genclis in April 2018 in order to co-develop and commercialize products arising from their disruptive technology.

About Genclis SA

Genclis is a privately-held biotechnology company incorporated in 2004 in Vandœuvre-lès-Nancy, France, that discovered a unique biological mechanism referred to as Transcription Infidelity (TI). TI produces RNA transcripts that differ from their originating DNA sequence. This mechanism explains the nonrandom occurrence of RNA to DNA divergences (RDD) that lead to translated proteins with sequences diverging from the canonical form. Genclis applies its artificial intelligence platform to extract, from large Genomic data sets, these low-intensity signals. Genclis has shown in both humans and animal models that specific RDD events shape selectively the repertoire of natural immunoglobulins and contribute to both allergy and other immunological disorders. Genclis has developed a diversified pipeline of disruptive diagnostic and therapeutic solutions that have and are completing pre-clinical evaluation. Genclis revenues grew >500 % to €2.2 million in fiscal year 2017 missing breakeven by less than 10 %. Genclis' objectives for 2018 are to further expand commercial activities in both human and veterinary medicine as well as in the food industry to reach profitability, while relentlessly pursuing developments of several other novel disruptive pre-clinical assets.

About Transcription Infidelity

Transcription Infidelity (TI) is a newly discovered ubiquitous epigenetic mechanism that increases RNA-DNA sequence divergences (RDD). TI was initially described and patented by Genclis¹ and has since been confirmed by several independent academic teams². TI can lead to base substitutions, insertions and deletions. The latter cause translational frameshifts that have important consequences in determining protein immunogenicity³. Genclis currently focuses on defining the effects of TI proteins translated from gapped RNA on normal and pathological humoral immunity.
