JENA, Germany, Dec. 21, 2022 (GLOBE NEWSWIRE) — InflaRx N.V. (Nasdaq: IFRX) (the “Company” or “InflaRx”), a clinical-stage biopharmaceutical company developing anti-inflammatory therapeutics by targeting the complement system, today announced that the Company has amended its existing co-development agreement with Staidson (Beijing) BioPharmaceuticals Co., Ltd. (together with its affiliates, “STS”) to support STS in its regulatory approval efforts for its proprietary drug candidate BDB-001 in China. Through the amendment of the existing co-development agreement, InflaRx will receive royalties of 10% on net sales of BDB-001 for the treatment of COVID-19 in China. InflaRx has granted STS an exclusive license for use in China to certain of InflaRx’s clinical, manufacturing and regulatory documentation regarding vilobelimab in order to support and facilitate the regulatory filing for BDB-001 for the treatment of severely ill COVID-19 patients with the Chinese National Medical Products Administration (NMPA).

Under the existing co-development agreement, BDB-001, an anti-C5a antibody that originated from the same cell line as vilobelimab, is being developed by STS for the treatment of severe COVID-19 and other inflammatory diseases in China. The existing co-development agreement contains an exclusive license restricted to development and commercialization within the territory of China and was granted to STS by InflaRx in 2015. STS is now planning to apply for regulatory approval in China of BDB-001 for the treatment of COVID-19.

In connection with amending the co-development agreement, InflaRx today also announced that it has entered into a share purchase agreement with Staidson Hong Kong Investment Company Limited, an affiliate of Staidson (Beijing) BioPharmaceuticals Co., Ltd., pursuant to which STS will purchase additional ordinary shares of InflaRx for an aggregate amount of USD 2.5 million at a price of USD 5.00 per share. The share purchase agreement also includes an option pursuant to which STS may purchase additional ordinary shares, at InflaRx’s discretion, for an aggregate amount of an additional USD 7.5 million. The option for such subsequent purchase will expire on the twelve-month anniversary of STS receiving regulatory approval for BDB-001 in China. Such subsequent investment would be made at the greater of USD 5.00 price per share or a 20% premium to the weighted average share price over the 15 trading days prior to the closing date of such subsequent investment.

“Given the recent steep increase in COVID-19 cases in China and the potential benefits of our anti-C5a technology, we are very happy that STS is advancing BDB-001 for the treatment of COVID-19 in China and are pleased to be able to support them as they work to bring a potentially life-saving treatment to this very large market,” said Prof. Niels C. Riedemann, CEO and Founder of InflaRx. “In addition, STS’s investment in InflaRx further strengthens both our near-term and long-term financial position as we advance our own vilobelimab product in several indications.”

Vilobelimab, InflaRx’s first-in-class monoclonal anti-human complement factor C5a antibody, has been submitted to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization for the treatment of critically ill, intubated, mechanically ventilated COVID-19 patients. InflaRx has all rights to vilobelimab. Vilobelimab is also in clinical development for the treatment of various indications, including pyoderma gangrenosum and cutaneous squamous cell carcinoma.
