NASHVILLE, Tenn., June 17, 2025 (GLOBE NEWSWIRE) -- Insight Molecular Diagnostics Inc. ("iMDx" or the "Company"), (NASDAQ:IMDX), formerly known as Oncocyte Corporation (NASDAQ:OCX), has announced its renaming and the relocation of its principal executive office from Irvine, California, to Nashville, Tennessee. The Company's common stock, listed on the Nasdaq Capital Market, will begin trading under the new stock symbol "IMDX," effective before the market opens on Wednesday, June 18, 2025.

The new name more accurately reflects the Company's expanded strategic direction and diversified product portfolio. Although oncology remains a key area of innovation, the new name better reflects its expanded strategic direction and diversified portfolio, including a focus on transplant medicine.

The Company remains committed to its goal of delivering a clinically available molecular diagnostic kit to expand testing access for kidney transplant patients, which it anticipates will unlock value in the estimated $1 billion addressable market for transplant rejection testing. So far in 2025, iMDx believes it has made disciplined and focused progress toward this goal, executing the critical steps required to transition from product development to commercialization.

To support these efforts, iMDx is relocating its principal executive office from Irvine, California to Nashville, Tennessee – home to the Company's CLIA-certified lab and a growing hub for healthcare innovation. The move reflects a strategic alignment of operations and proximity to both core infrastructure and industry talent. The Company also expects to maintain its laboratory and research and development center in Göttingen, Germany.

"We believe that iMDx is just getting started in its value-creation journey, and that these changes reflect our renewed priorities and focus," iMDx Chief Financial Officer Andrea James said. "We believe the rebranding and design of the new logo symbolically support our aim to put doctors, laboratory technicians, and researchers at the center of what we do, to equip them with more diagnostic tools to better serve their patients."

The new name leverages iMDx's existing rights to the name Insight Genetics, which it acquired in 2020. In addition, the Company's CLIA-certified and CAP-accredited lab in Nashville launched as "Insight Molecular Labs," in 2013 and maintains that name today. The Company's new iMDx logo features DNA banding patterns on the "i," as well as a centered MD – for medical doctor, reflecting iMDx's healthcare provider-centric philosophy. Further, "Dx" is a common industry abbreviation for both diagnostics and diagnosis.

"The new iMDx logo is more than a visual refresh – it's a reflection of who we are and what we stand for," said Julie Walker, Associate Director, Marketing at iMDx. "The vibrant, data-inspired design within the 'i' represents the molecular complexity we decode every day, while the bold, modern typography speaks to our clarity, precision, and trust. At the heart of the logo is 'MD' – a deliberate reminder that medical professionals, researchers, and the patients they serve are at the center of everything we do. This new identity captures our mission to provide deep insights through science, and empower better decisions in transplant care, oncology, and beyond."

Booth Exhibition at ESOT in London

The Company will be exhibiting at the European Society for Organ Transplantation (ESOT) Congress in London in late June 2025.

Attendees are invited to visit the iMDx booth (D46) to learn more about its GraftAssureIQ™ pilot site program, which is a research-use-only ("RUO") pilot initiative designed to support transplant centers engaged in cutting-edge R&D.

Through this program, iMDx is partnering with leading institutions to accelerate scientific discovery in transplant medicine and generate real-world insights using its donor-derived cell-free DNA (dd-cfDNA) testing technology.

The Company encourages research institutions to stop by to explore collaboration opportunities and see how GraftAssureIQ has the potential to advance their respective center's research goals.

Updated Product Mapping

As part of the rebranding initiative, iMDx is also retiring the VitaGraft name and unifying its transplant diagnostics under the GraftAssure™ brand. The updated nomenclature will better align with each product's regulatory classification and intended use:

GraftAssureCore – The Company's lab-developed test (LDT), currently reimbursed by CMS and performed at its CLIA-certified laboratory in Nashville.

GraftAssureIQ – An RUO kit intended for non-clinical applications and clearly labeled as such.

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.

Summary:

VitaGraft Kidney (LDT) → GraftAssureCore
GraftAssure (RUO) Kit → GraftAssureIQ
VitaGraft+ (IVD) Kit → GraftAssureDx

These changes mark an important milestone in the Company's evolution and reflect a broader mission: to democratize access to high-quality, molecular diagnostic testing that improves patient outcomes.

Insight Molecular Diagnostics Inc., or iMDx (formerly Oncocyte Corporation), is a pioneering diagnostics technology company whose mission is to democratize access to novel molecular diagnostic testing to improve patient outcomes. Investors may visit https://investors.imdxinc.com/ for more information.

The Company's flagship 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 the Company is now in the process of commercializing that technology using what it believes to be a market disruptive approach.

Per recent rebranding announcements, GraftAssure is becoming the umbrella brand for the Company's dd-cfDNA test portfolio. The Company is in the process of rebranding its VitaGraft assay (also 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. The Company is also in the process of rebranding its RUO test kit, GraftAssure, as "GraftAssureIQ," and rebranding its future in-vitro diagnostic (IVD) test kit as "GraftAssureDx."
