On January 21, 2021, Relief announced the implementation of a new Share Subscription Facility ("SSF") in the amount of up to CHF 50 million with the Company’s main shareholder, GEM Global Yield LLC SCS.

Under the terms of the SSF, Relief has the right to periodically, during a timeframe of up to three years, issue and sell shares to GEM. Under the facility, GEM undertakes to subscribe to or acquire ordinary registered RELIEF THERAPEUTICS Holding AG shares upon Relief's exercise of a draw down notice. In accordance with the customary terms of the SSF agreement, Relief will control the timing and maximum amount of any draw down, and retains the right, not the obligation, to draw down on the full commitment amount.

As of December 31, 2022, no funds have been drawn down from the current SSF agreement.

We cannot speculate on the likelihood or timing of FDA approvals. In March 2021, Relief’s partner, NeuroRx, reported top-line 60-day results from the phase 2b/3 clinical trial in critical COVID-19 patients with respiratory failure. On the basis of these findings, in May 2021, NRx Pharmaceuticals, Inc. (NRx) (now the parent of NeuroRx) submitted an application to the FDA for Emergency Use Authorization (EUA), which was subsequently declined in November 2021. In January 2022, NRx announced that it had submitted an application to the FDA seeking EUA for the use of aviptadil to treat patients with critical COVID-19 who are at immediate risk of death from respiratory failure despite treatment with approved therapy including remdesivir and who are ineligible for enrollment into the ACTIV-3b NIH-sponsored trial, which was subsequently denied in July 2022. 

The U.S. phase 2/3 study with the inhaled formulation of RLF-100® was initiated by NeuroRx, Inc. in February 2021. In March 2022, NRx announced the study was paused. 

In September 2020, Relief entered into a binding collaboration agreement with NeuroRx (the “Collaboration Agreement”) which established the terms under which both parties would collaborate and assist each other to maximize the commercial value of each parties’ territories related to intravenous and inhaled aviptadil for the treatment of COVID-19 and other related pulmonary conditions. However, based on numerous breaches of the Collaboration Agreement by NeuroRx, in October 2021, Relief filed a lawsuit against NeuroRx and its then CEO, Dr. Jonathan Javitt, for multiple breaches of the Collaboration Agreement. The complaint, among other remedies, sought damages, an order compelling defendant to comply with multiple provisions of the Collaboration Agreement, and a declaration directing NeuroRx to deliver the entire data set from the Phase 2b/3 clinical trial of intravenously-administering aviptadil to Relief. On January 10, 2022, NeuroRx filed a complaint against Relief alleging that the Company is in breach of the Collaboration Agreement and has thus repudiated and cancelled the Collaboration Agreement. Additionally, NeuroRx’s claims include a count for defamation.

On November 14, 2022, Relief and NRx announced they had entered into a definitive settlement agreement to resolve all matters relating to the pending litigation. At the closing of this settlement, held on December 19, 2022, (i) NRx transferred to Relief all of the assets that it previously used in its aviptadil development program, including its regulatory filings, patent applications, clinical data, and the formulation of the aviptadil product it was previously developing, (ii) Relief has the exclusive right and control going forward to develop and commercialize an aviptadil product, (iii) Relief has agreed to use commercially reasonable efforts to continue the existing Right to Try Program for aviptadil in the United States for at least 2 years, (iv) Relief will pay NRx milestone payments if it can successfully obtain commercial approval of an aviptadil product (whether for COVID-19 or any other indication), (v) Relief will pay NRx royalties based on a percentage of future sales of an aviptadil product (whether for COVID-19 or any other indication), up to a maximum of $30 million in the aggregate, (vi) NRx Pharmaceuticals has agreed not to compete in the development of an aviptadil product in the future, and (vii) Relief and NRx Pharmaceuticals have dismissed their pending litigation.

Relief holds a patent covering potential formulations of RLF-100^® in the United States valid until at least July 2029, with extension opportunities up to five years, as well as in the EU and Rest of World (Great Britain, Germany, Turkey, Spain, Switzerland, Netherlands, Denmark, Ireland, Austria, PRC and Mexico) valid until at least 2026, excluding extension opportunities comparable to the U.S. The acquisition of AdVita Lifescience GmbH in July 2021, enabled us to strengthen our intellectual property position with pending intellectual property rights that cover an improved formulation of the inhaled version of RLF-100^® (aviptadil) and its potential application for the treatment of acute respiratory distress syndrome (“ARDS”) unrelated to COVID-19 infection, as well as in other pulmonary disorders, including sarcoidosis, berylliosis and checkpoint inhibitor-induced pneumonitis, for which AdVita has already filed pending patent claims. 

In April 2021, Relief announced the initiation of a phase 2 trial evaluating the inhaled formulation of RLF-100^® for the prevention of COVID-19-related ARDS (the Leuppi study) (NCT04536350), which is a randomized, double-blind, placebo-controlled phase 2 investigator-sponsored trial being conducted at several clinical sites in Switzerland. The trial is at an advanced stage of recruitment and is slated to report top-line data later this year (subject to enrollment of eligible patients).

Aviptadil remains a molecule with a well-established mechanism of action and widely documented clinical evidence of biological activity, as well as a favorable human safety and tolerability profile established across two decades of clinical evaluation. As such, Relief believes that the drug merits continued assessment across an array of pulmonary conditions, regardless of whether the drug is ever approved for the treatment of COVID-19. Relief intends to initiate a clinical trial of RLF-100^® in early 2023 in patients with pulmonary sarcoidosis, a chronic, rare and debilitating pulmonary disease for which there are no treatments approved and for which Relief has received Orphan Drug designation from the FDA. Relief plans to explore RLF-100^® in checkpoint inhibitor-induced pneumonitis (CIP), an indication in which Relief’s wholly owned subsidiary, AdVita LifeScience GmbH, obtained method-of-use patent protection for aviptadil in February 2022. Additionally, Relief intends to conduct European proof-of-concept clinical development of RLF-100^® in the treatment of chronic berylliosis, an orphan lung disease for which there are no treatments approved, and that is characterized by severe inflammation of the lungs, coughing and increasing breathlessness (dyspnea). Please see the Pipeline-RLF-100^® (aviptadil) section of the website for details.

OLPRUVA™ is a proprietary powder formulation of sodium phenylbutyrate (NaPB). The formulation is designed to be both taste-masked and immediate release. OLPRUVA is being developed using a microencapsulation process for the treatment of various inborn errors of metabolism, including urea cycle disorders (UCDs) and maple syrup urinedisease (MSUD). OLPRUVA microparticles consist of a core center, a layer of active drug, and a taste-masking coating that quickly dissolves in the stomach to avoid a bitter taste while still allowing for rapid systemic absorption. OLPRUVA’s taste-masked formulation is designed to improve the palatability of NaPB and could make it a compelling alternative to existing NaPB-based treatments, as the unpleasant taste associated with NaPB is cited as a major impediment to patient compliance with those treatments.

Relief anticipates commercialization of OLPRUVA for UCDs in the U.S. in the first half of 2023, after which Relief, in accordance with its collaboration agreement with Acer, intends to submit a Marketing Authorization Application for approval of OLPRUVA for the treatment of UCDs in the U.K. and EU. There can be no assurance, however, that OLPRUVA will be approved for commercialization in the U.K. or the EU.

On March 22, 2021, Relief and Acer announced the signing of a collaboration and license agreement for the worldwide development and commercialization of OLPRUVA^™. Under the terms of the agreement, Acer will receive approximately $10 million in cash upon signing (originally $14 million, which was offset by cancellation of the $4.0 million outstanding balance of the prior loan from Relief to Acer following the signing of an exclusivity option agreement in January 2021 and a small amount of accrued interest). In addition, Relief has agreed to pay up to $20 million in U.S. development and commercial launch costs for the urea cycle disorders (UCDs) and maple syrup urine disease (MSUD) indications. Acer will retain development and commercialization rights in the U.S., Canada, Brazil, Turkey and Japan. The companies will split net profits from Acer’s territories 60:40 in favor of Relief. In addition, Relief has licensed the rights for the rest of the world, where Acer will receive from Relief a 15% royalty on all net sales and other revenues received in Relief’s territories. Acer may also receive a total of $6 million in development milestone payments following the first European (EU) marketing approvals for UCDs and MSUD.
