SPECTRAL MEDICAL ANNOUNCES PUBLICATION OF TIGRIS TRIAL METHODS PAPER AND SIMULATION OF RESULTS

Spectral Medical Inc. has published its Tigris trial methods paper in Critical Care, which discusses the use of Bayesian methods in clinical trial design. Simulation studies incorporating historical data from a 179-patient subgroup of Spectral's EUPHRATES trial combined with data from the ongoing Tigris trial demonstrated an increase in power across a range of observed hypothetical results.

Dr. John Kellum, Chief Medical Officer of Spectral Medical, commented, "We are pleased to see the publication of this paper, in a major scientific journal. The analysis clearly indicates that our trial strategy is highly likely to succeed and not only will this support our FDA approval for PMX, but will also have a major impact on how trials in the ICU are conducted in the future. The simulations involving over 2,000 potential trial results show that using the planned 75% weight on the prior EUPHRATES data, an observed absolute risk reduction for mortality of 7% in Tigris is at approximately the 95% probability threshold for declaring PMX effective. Current results from Tigris are far in excess of this threshold."

Chris Seto, Chief Executive Officer of Spectral commented, "We are also pleased to see all of our study site investigators participating as authors on the study as we continue to work aggressively to complete the enrollment of our Tigris Trial. We are proud to be a part of this effort to help patients suffering from endotoxic septic shock and hope to bring a new standard of care to the market."

About Spectral

Spectral is a Phase 3 company seeking U.S. FDA approval for its unique product for the treatment of patients with septic shock, Toraymyxin(TM) ("PMX"). PMX is a therapeutic hemoperfusion device that removes endotoxin, which can cause sepsis, from the bloodstream and is guided by the Company's Endotoxin Activity Assay (EAA(TM)), the only FDA cleared diagnostic for the risk of developing sepsis.

PMX is approved for therapeutic use in Japan and Europe, and has been used safely and effectively on more than 340,000 patients to date. In March 2009, Spectral obtained the exclusive development and commercial rights in the U.S. for PMX, and in November 2010, signed an exclusive distribution agreement for this product in Canada. In July 2022, the U.S. FDA granted Breakthrough Device Designation for PMX for the treatment of endotoxic septic shock. Approximately 330,000 patients are diagnosed with septic shock in North America each year.
