Ongoing Phase II preclinical study data for Co-Dx PCR MTB and HPV tests support advancement to clinical performance testing

SALT LAKE CITY , Dec. 9, 2025 /PRNewswire/ -- Co-Diagnostics, Inc. (Nasdaq: CODX) ("Co-Dx" or "the Company"), a molecular diagnostics company with a unique, patented platform for the development of molecular diagnostic tests, today announced that CoSara Diagnostics Pvt. Ltd. ("CoSara"), the joint venture ("JV") between Ambalal Sarabhai Enterprises Limited (ASE Group) and Co-Dx, will participate and host a booth at VIROCON 2025, taking place December 8-10 at the Conrad Hotel in Pune, Maharashtra, India.

CoSara is currently supporting the second phase of the Company's preclinical studies for the Co-Dx PCR MTB (tuberculosis) test and Co-Dx PCR HPV multiplex test on the Co-Dx PCR point-of-care (PoC) platform*. Phase I of the MTB test studies included 354 clinical specimens from sputum and tongue swabs to provide early sensitivity and specificity assessments, while Phase II has evaluated 211 sputum specimens in a comparison evaluation against other tests to establish concordance for Mycobacterium tuberculosis detection. The studies are being conducted in preparation of advancement to clinical performance testing, required by Indian regulatory authorities prior to submission.

Phase I of the preclinical studies for the 8-type HPV multiplex test, designed to identify the presence of eight different human papillomavirus genotypes, evaluated 286 clinical specimens to validate and optimize the Co-Primers® test chemistry for HPV. Three of the eight genotypes are classified as high-risk for cancer, and in Phase II, 53 specimens have been analyzed to date to facilitate the differential detection of the three high-risk HPV genotypes as the application algorithm continues to be trained, refined and optimized.

The Company believes that data gathered thus far in the preclinical studies for both tests support advancement to clinical performance testing, as part of the pathway to regulatory submissions.

Attendees interested in learning more about CoSara products, including the TB and HPV tests on the Company's upcoming Co-Dx PCR platform, are encouraged to stop by at VIROCON 2025. CoSara will be available for meetings and interactions at CoSara's booth.

VIROCON 2025 is organized by the India Council of Medical Research - National Institute of Virology ("ICMR-NIV"), with this year's theme being "Changing Landscape in Human, Animal, and Plant Viruses: Bridging Basic Science, Innovations and Public Health." The conference is expected to provide a platform for productive scientific deliberations and collaborations aimed at developing solutions to contain the viral epidemics that threaten human, animal, plant, aquatic and environmental health.
