Spectral Medical Provides November Tigris Trial Update

• 79 patients enrolled

TORONTO, Dec. 04, 2023 (GLOBE NEWSWIRE) -- Spectral Medical Inc. (“Spectral” or the “Company”) (TSX: EDT), a late-stage theranostic company advancing therapeutic options for sepsis and septic shock, today provided an update for the month of November on the Company’s Tigris trial, a Phase 3 follow-on study evaluating the use of Polymyxin B Hemoperfusion (“PMX”) in a randomized controlled trial of adults treated for endotoxemia and septic shock.

• 79 patients enrolled to date and continuing to close in on the interim target of 90 patients, an important milestone as the Company’s strategic commercial partner, Baxter (NYSE:BAX), will have the opportunity to view the data as well as provide a second milestone payment to Spectral.
• Currently 20 Tigris trial sites, with near term onboarding of new, high quality clinical sites.
• Crude mortality results at both 28-day (primary endpoint) and at 1-year, thus far, continue to exceed efficacy targets.

Dr. John Kellum, Chief Medical Officer of Spectral, commented, “In November we experienced strong enrollment into Tigris despite the U.S. Thanksgiving holiday, with five patient enrollments in the last six weeks. We continue to make progress opening additional sites, which should positively impact the pace of enrollment. Additionally, the high rates of influenza that we are witnessing across the southern U.S. and California could have a positive impact on our enrollment, as influenza is often a trigger for bacterial sepsis. Overall, we are rapidly advancing our Tigris trial and remain highly encouraged by the outlook, given the fact preliminary mortality data continues to exceed our expectations.”

“We continue to be very bullish on the outcome of the Tigris trial. We recently published a Bayesian methodology paper in a major scientific journal. The analysis clearly indicates that our trial strategy is highly likely to succeed in our goal of FDA approval for PMX. 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,” said Chris Seto, Chief Executive Officer of Spectral. “Additionally, we are making steady headway towards reaching out our interim count of 90 patients, which is expected to play as a major catalyst for the Company.”
