Jena, Germany, 23 May 2019 – InflaRx (Nasdaq: IFRX), a clinical-stage biopharmaceutical company developing anti-inflammatory therapeutics by targeting the complement system, today reported financial and operating results for the first quarter ended March 31, 2019.

“It is an exciting time for InflaRx, as we await top-line results from our Phase IIb trial with IFX-1 in Hidradenitis Suppurativa, our lead indication,” said Prof. Niels C. Riedemann, Chief Executive Officer and Founder of InflaRx. “While we look forward to these HS results, we have also continued to execute within our other clinical development programs. We now have Phase II trials in ANCA-associated vasculitis ongoing in both Europe and the US, and expect to initiate the Phase IIa trial in Pyoderma Gangraenosum in short order. I am pleased with the company’s continued development, and with the addition of key new hires, and the steadfast support of our shareholders. I believe that we are well positioned to exploit the potential of our anti-C5a antibody technology to pursue additional high-value pipeline opportunities going forward.”

Q1 2019 corporate highlights

• Expanded U.S. operations with opening of corporate office in New York City and hiring of senior executives.
• Richard Brudnick, CBO of Codiak BioSciences, appointed as Non-Executive Director, subject to shareholder approval at the upcoming annual general meeting, which will take place on May 23, 2019. He is currently serving as a Non-Voting Observer.
• New data with IFX-1 from completed Phase IIa trial in Hidradenitis Suppurativa, or HS presented at the 8^th Conference of the European Hidradenitis Suppurativa Foundation. The retrospective long-term data showed sustained remissions and median time to first flare of almost seven months, after only eight weeks of treatment.
• Approval granted by Health Canada to initiate a Phase IIa clinical trial evaluating IFX-1 in Pyoderma Gangraenosum, a debilitating, rare autoimmune disease marked by large, painful ulcers. This is the third inflammatory disease for which InflaRx is developing IFX-1. InflaRx plans to start enrollment in due course.
• In May, InflaRx started a second Phase II study with IFX-1 in ANCA-Associated Vasculitis. The first patient has been treated in the IXchange trial. The trial is planned to enroll approximately 80 patients at about 60 sites in up to 12 European countries and Russia.
• IFX-1 subcutaneous version. We are continuing our preclinical development of a subcutaneous version of IFX-1 specifically for the treatment of HS and potentially other indications.

Q1 2019 financial highlights

Cash and cash equivalents plus securities and other investments totaled €150.1 million as of March 31, 2019, compared to €156.4 million as of December 31, 2018. Cash and cash equivalentsamounted to €47.2 million as of March 31, 2019 (December 31, 2018: €55.4 million) and marketable securities €102.9 million (December 31, 2018: €100.9 million).

Net cash used in operating activities increased to €8.5 million in Q1 2019, compared to €5.7 million in Q1 2018, mainly due to the increase of cash expenses, such as third-party expenses for manufacturing and clinical trials for our lead program IFX-1 and personnel expenses at InflaRx.

Research and development expenses increased to €7.7 million for Q1 2019 (Q1 2018: €5.5 million). The principal drivers of the increase were CRO expenses associated with preclinical studies and clinical trials conducted for IFX-1 as well as manufacturing costs.

General and administrative expenses amounted to €3.3 million in Q1 2019, compared to €3.0 million in Q1 2018. This increase is primarily attributable to an increase in employee-related costs.

Net financial result in Q1 2019 (€1.1 million) consisted of €0.8 million interest income and €0.3 million net exchange gain, compared to a net financial loss of €1.9 million in Q1 2018. This was mainly due to lower foreign exchange losses of our U.S. Dollar term deposits (€2.1 million) and higher interest income (€0.5 million).

Net loss for the first quarter of 2019 was €9.8 million or €0.38 per common share (basic and diluted), compared to €10.3 million or €0.43 per common share (basic and diluted) in Q1 2018.

Additional information regarding these results is included in the notes to the consolidated financial statements as of and for the quarter ended March 31, 2019, which can be found on the InflaRx website in the Investors section.
