GENEVA, SWITZERLAND / ACCESSWIRE / April 3, 2023 / RELIEF THERAPEUTICS Holding SA (SIX:RLF)(OTCQB:RLFTF)(OTCQB:RLFTY) (Relief Therapeutics, or Relief), a biopharmaceutical company committed to delivering innovative treatment options with the potential for transformative outcomes to benefit those suffering from select specialty and rare diseases and disorders, today reported its financial results for the full-year ended December 31, 2022 and provided a corporate update. The Relief Therapeutics 2022 Annual Report, including management's discussion and analysis, financial statements and results of operations for the year ending December 31, 2022, is available for download on the company's website.

"We made substantial progress in our transformation of Relief Therapeutics into a fully integrated, commercial-stage biopharmaceutical company in 2022, strengthening our intellectual property portfolio with multiple new patents and with the launch of our PKU GOLIKE^® line of products in the U.S. in October, and the subsequent launch of the new PKU GOLIKE BARs™ in the U.S. and Europe earlier this year. In late December, we announced the U.S. FDA approval of OLPRUVA™ for the treatment of patients with urea cycle disorders with our collaboration partners at Acer Therapeutics," said Jack Weinstein, chief executive officer of Relief Therapeutics. "We also announced new stability data for RLF-100^®, our novel formulation of aviptadil acetate, which has been shown to be shelf-stable at temperatures suitable for shipping and long-term storage. We believe RLF-100 has significant potential clinical and commercial value and intend to pursue development of this product candidate for treatment of several debilitating lung disease indications."

"We also built out our U.S. commercial organization and strengthened our management team, while continuing to advance other elements of our diversified pipeline of risk-mitigated product candidates toward significant catalysts," continued Mr. Weinstein. "In 2022 we also launched a new initiative in genetic medicine focused on inherited metabolic disorders, which is being led by Dr. Serene Forte who joined Relief in July. To support this endeavor, we also recently announced the appointment of Dr. Guangping Gao, a pioneer and global thought leader in the field of molecular genetics and viral vector gene therapy, to serve as the chair of our newly established scientific advisory board. Looking ahead to the balance of 2023, we continue to execute on the revised financing and listing strategy we announced in February. We maintain a lean organization, with a strong, experienced leadership team that has the proven ability to execute our disciplined, cost-effective, capital-efficient approach to drug development and deliver growth. We look forward to concluding the remaining steps on our pathway to a dual listing of our ordinary shares on the Nasdaq Stock Market and further advancing our development plans in 2023, and to realizing the full potential of the Relief Therapeutics portfolio for patients and our shareholders," said Mr. Weinstein.

2022 & EARLY 2023 HIGHLIGHTS

OLPRUVA^TM (sodium phenylbutyrate) for oral suspension FDA Approval

• U.S. Food and Drug Administration approved OLPRUVA™ (sodium phenylbutyrate for oral suspension for the treatment of certain patients living with urea cycle disorders (UCDs) involving deficiencies of carbamylphosphate synthetase (CPS), ornithine transcarbamylase (OTC) or argininosuccinic acid synthetase (AS).
  • Collaboration partner Acer Therapeutics (ACER) announced preliminary launch activities in March 2023; with commercial and medical affairs teams in place to support the U.S. launch in Q2 2023 and product availability expected in July 2023.
  • ACER presented UCD survey data at 44th annual meeting of the Society for Inherited Metabolic Disorders (SIMD) in March 2023. The survey data were designed to quantify preferences of healthcare providers who treat patients with UCDs, and results showed taste and odor are the most important attributes influencing overall prescription and patient adherence to UCD treatments.

PKU GOLIKE^® for the Treatment of Phenylketonuria (PKU)

• Relief's newly assembled U.S. commercial team and a leading national health services company serving as exclusive distributor initiated the launch of its PKU GOLIKE^® line of products in the U.S. in October. The PKU GOLIKE^® family of products are next-generation, prolonged-release amino acid medical foods for the dietary management of phenylketonuria (PKU).
• In early 2023, Relief also launched the newest product in the PKU GOLIKE line, the PKU GOLIKE BAR™ in the U.S. and Europe.
• The Company presented results of pre-clinical research evaluating the metabolic impact of PKU GOLIKE^® on nitrogen balance, muscle strength and glucose at SIMD 2023. Data presented in a poster session summarized acute and long-term metabolic effects of PKU GOLIKE supplementation on the utilization of amino acids and glucose metabolism in a pre-clinical rat model using biomarkers for muscle metabolism, functional muscle performance and a glucose tolerance test. Beneficial effects were observed on amino acid oxidation, muscle metabolism, grip strength and glucose tolerance in healthy rats.

RLF-100^® (aviptadil acetate)

• In November, Relief announced six-month stability data for its new proprietary formulation of aviptadil acetate, RLF-100^®; high-purity levels were demonstrated at all temperatures tested (refrigerated, room temperature).
  • Results demonstrate novel RLF-100^® formulation to be shelf-stable at temperatures suitable for shipping and long-term storage.
• RLF-100^® was granted Orphan Drug designation (ODD) for pulmonary sarcoidosis by the FDA.
• In December, Relief announced a definitive settlement agreement was reached with its former collaboration partner NeuroRx, Inc. (NRx) to resolve litigation, resulting in transfer to Relief of all assets previously used in the aviptadil development program.

RLF-TD011

• Patient enrollment was initiated in a proof-of-concept, investigator-initiated clinical trial of RLF-TD011 for the treatment of epidermolysis bullosa (EB), a rare, inherited skin disease characterized by widely distributed, painful, chronic wounds that easily become infected, resulting in an elevated risk of sepsis and death.
  • The study (NCT05533866) is currently enrolling up to 17 patients diagnosed with junctional epidermolysis bullosa (JEB) or dystrophic epidermolysis bullosa (DEB) with S. aureus or P. aeruginosa culture-positive wounds at Ann & Robert H. Lurie Children's Hospital of Chicago.
• Relief received the approval of an independent IRB for an investigator-initiated trial evaluating RLF-TD011 as an adjunctive treatment for cutaneous t-cell lymphoma (CTCL) (NCT05728879); the study will evaluate the effect of RLF-TD011, a patent-protected hypochlorous acid topical spray, on the microbiome of CTCL skin lesions and determine tolerability, symptom improvement and potential for reducing lesion size and skin disease activity.

RLF-OD032 for the Treatment of PKU

• In July, Relief acquired the worldwide commercialization rights (except in the United Kingdom) for a novel dosage form of an already FDA-approved prescription drug for the treatment of PKU from Meta Healthcare Ltd.
