• Steven Tahmooressi to lead global marketing efforts for GraftAssure family of assays and future products
• Brings 25 years of experience driving new product adoption across geographies in transplantation, oncology and immunology

NASHVILLE, Tenn., Oct. 13, 2025 (GLOBE NEWSWIRE) -- Insight Molecular Diagnostics Inc., (Nasdaq: IMDX), (iMDx), today announced that it has welcomed Steven Tahmooressi to its executive leadership team as the company prepares to launch its first clinical kitted assay in 2026.

As Vice President of Marketing, Mr. Tahmooressi will be responsible for leading transplant and oncology assay marketing, bringing more than 25 years of healthcare industry experience, including a strong history in supporting the transplantation community, ranging from U.S. sales and marketing leadership to regional and global commercialization.

Mr. Tahmooressi joins iMDx most recently from Astellas Pharma where he was the Global Brand Lead of Established Products Marketing covering its transplant, urology and oncology brands. He also worked in various career progressing commercial roles during his respective tenures at Abbott Laboratories and Bristol-Myers Squibb.

“After three years of laser-focused investing in our kitted product for transplant rejection testing, we are now approaching the critical product launch phase of GraftAssureDx,” iMDx CEO Josh Riggs said. “As we prepare for FDA authorization of GraftAssureDx next year, we are thrilled to welcome Steven to the team to lead our marketing efforts on this mission-critical product. He brings a proven track record of new product marketing to drive commercial adoption in the U.S., Europe, Japan, Middle East, and the Asia Pacific regions.”

Mr. Riggs added, “With a relentless focus on the customer, Steven has led multiple successful U.S. and international product launches in high-touch fields of medicine including transplantation and immunology. Since starting with iMDx in late September, he has hit the ground running, including meeting with customers and supporting our successful presence at the annual meeting of the American Society of Histocompatibility & Immunogenetics in Orlando this month.”

The mission at iMDx is to democratize access to molecular diagnostic testing – and the company’s first targeted strategic market is transplantation rejection testing, through its GraftAssure family of assays. These assays represent iMDx’s initial flagship technology. The assay family includes GraftAssureCore, the company’s laboratory-developed test (LDT), currently reimbursed by Medicare and performed at its CLIA-certified laboratory in Nashville. GraftAssureIQ became available for purchase in summer 2024 for research use only, while GraftAssureDx is in development as a clinical molecular diagnostic test kit, which can be distributed to hospitals to expand and improve testing access for kidney transplant patients.
