IMDX Enrolls First Patient in GraftAssureDx Clinical Trial and Welcomes New Hospital Participants
- iMDx’s ClinicalTrials.gov listing now names 10 leading transplant centers, up from 5 previously
- GraftAssureDx remains on track for FDA submission by end of 2025, commercial launch in 2026
NASHVILLE, Tenn., Sept. 08, 2025 (GLOBE NEWSWIRE) -- Insight Molecular Diagnostics, or iMDx, (Nasdaq: IMDX), today announced that it is actively enrolling patients in its clinical trial to assess GraftAssureDx and that last week, it enrolled the first patient. In addition, now names 10 leading transplant centers, up from five previously.
The ongoing clinical trial is an important step toward obtaining regulatory authorization to deliver an organ transplant rejection monitoring test kit to the estimated $1 billion addressable market for kitted transplant rejection testing.
The goal of this observational study is to determine that the GraftAssureDx kitted test can assess rejection in kidney transplant recipients. The company anticipates enrolling up to 125 patients and completing the trial by year-end.
“We are proud of our momentum at the start of this study as well as the top-tier roster of sites participating,” said iMDx CEO Josh Riggs. “I would also like to congratulate iMDx Chief Science Officer Prof. Dr. Ekkehard Schuetz and our clinical team for their diligence and timeliness in initiating this study. The first patient was enrolled on September 2nd, sites now are actively enrolling, and we remain highly focused on submitting GraftAssureDx for FDA review by year end.”
The GraftAssureDx kitted test would be the third version in the GraftAssure family of assays and iMDx is seeking FDA authorization for its clinical use. Currently, iMDx offers GraftAssureCore, which is its laboratory developed test that has achieved , and GraftAssureIQ, its research-use-only kitted assay that is available for sale for research purposes.

iMDx Transplant Products and Product Candidates in Development
The company’s flagship transplant testing technology quantifies a molecular biomarker known as donor-derived cell-free DNA (dd-cfDNA). The company’s scientists in Germany and the U.S. have played a critical role over the past decade in developing the science that helped establish dd-cfDNA as a trusted biomarker of transplant rejection, and iMDx is now commercializing that technology using a market disruptive approach. Its transplant diagnostics under the GraftAssure™ brand include the following:
- GraftAssureCore – The company’s laboratory-developed test (LDT), currently reimbursed by CMS and performed at its CLIA-certified laboratory in Nashville. The company is in the process of rebranding its VitaGraft assay (previously known as VitaGraft Kidney), which is a lab developed test, under the name GraftAssureCore. For purposes of this press release, references to “GraftAssureCore” shall be deemed to include the test previously marketed as VitaGraft.
- GraftAssureIQ – A research-use-only (RUO) kit intended and labeled for non-clinical applications.
- GraftAssureDx – The in vitro diagnostic (IVD) kit currently in development for use in clinical decision-making, which the company intends to submit for FDA authorization in 2025.
