Co-Diagnostics revamps COVID-19 test for FDA clearance amid stability concerns

Co-Diagnostics, Inc. has announced that it is withdrawing its 510(k) clearance application for its Co-Dx PCR COVID-19 test following discussions with the Food and Drug Administration (FDA) regarding shelf-life stability concerns. Instead of pursuing approval for the current version, the company plans to submit an enhanced version that addresses the regulatory feedback. The decision follows a collaborative review process in which the FDA identified the need for improvements in the test’s ability to detect potential deterioration of a key component over time.

The company, which specializes in molecular diagnostics with a patented Co-Dx PCR platform, expressed confidence in the performance of its test but acknowledged the importance of meeting FDA clearance standards for long-term market viability. The revised version of the test will integrate improvements to extend shelf-life stability, ensuring that the product meets the highest regulatory and quality standards.

What Are the Key Changes in the New Co-Dx PCR COVID-19 Test?

Co-Diagnostics aims to address the FDA’s feedback by making critical refinements to the Co-Dx PCR COVID-19 test. One of the primary areas of enhancement will focus on optimizing the shelf-life stability of a test component, ensuring consistent performance over time. These adjustments will allow the test to maintain reliability in various storage conditions, a crucial factor in obtaining 510(k) clearance for commercial use.

Beyond addressing shelf-life stability, the company sees this as an opportunity to incorporate the latest advancements in its Co-Dx PCR platform. By refining its proprietary PCR technology, Co-Diagnostics expects to improve not just the COVID-19 test but also future diagnostic products. The company is preparing for an over-the-counter (OTC) submission, aiming to expand access to its COVID-19 test for at-home and point-of-care testing.

The resubmission process will involve gathering additional clinical evaluation data to support the performance of the improved test. This data will play a crucial role in securing FDA approval, ensuring that the product meets stringent regulatory requirements while providing accurate and reliable results.

How Will the New Co-Dx PCR Platform Impact Infectious Disease Testing?

Co-Diagnostics’ decision to enhance its COVID-19 test aligns with its broader vision of advancing molecular diagnostics. The company is investing heavily in the development of a next-generation Co-Dx PCR platform, which will serve as the foundation for multiple diagnostic tests beyond COVID-19. These include tests for tuberculosis (TB), HPV, and upper respiratory multiplex infections.

The integration of an advanced PCR platform is expected to streamline manufacturing processes, allowing for the production of a new generation of diagnostic tests that are more efficient and cost-effective. Co-Diagnostics is positioning itself as a leader in at-home and point-of-care diagnostics, ensuring that patients and healthcare providers have access to cutting-edge molecular testing solutions.

What Role Does Co-Diagnostics’ India Expansion Play in Its Growth Strategy?

In addition to refining its COVID-19 test, Co-Diagnostics is expanding its global footprint through strategic initiatives, including its operations in India. In December 2024, the company, along with its joint venture CoSara Diagnostics, inaugurated a new oligonucleotide synthesis facility in Ranoli, India. This facility was established to support the “Make in India” initiative, reinforcing the company’s commitment to localized manufacturing and in-house production of Co-Primers chemistry.

The new facility is expected to play a crucial role in advancing Co-Diagnostics’ PCR testing capabilities. By synthesizing Co-Primers in-house, the company aims to improve supply chain efficiency and reduce dependence on external suppliers. This expansion positions Co-Diagnostics to scale up its manufacturing operations and accelerate regulatory approvals for its PCR tests in India’s high-tech healthcare market.

With tuberculosis continuing to be a major global health concern, Co-Diagnostics has highlighted its commitment to introducing a PCR-based TB test as part of its long-term diagnostic strategy. According to the World Health Organization (WHO), 10.8 million people contracted tuberculosis in 2023, with the disease causing approximately 1.25 million deaths. These figures underscore the urgent need for advanced diagnostic solutions, which Co-Diagnostics aims to address through its Co-Dx PCR platform.

How Will Co-Diagnostics’ Innovations Shape the Future of Molecular Testing?

Co-Diagnostics’ focus on refining its COVID-19 test and expanding its broader diagnostic portfolio reflects a strategic shift toward next-generation PCR diagnostics. By addressing FDA concerns and introducing an enhanced COVID-19 test, the company is strengthening its regulatory standing while ensuring that its products meet the evolving needs of the healthcare market.

The company’s ability to adapt its PCR technology to multiple infectious diseases, from COVID-19 to tuberculosis and HPV, highlights its long-term vision for molecular diagnostics innovation. As Co-Diagnostics advances toward the commercialization of its Co-Dx PCR platform, its investments in regulatory compliance, manufacturing efficiency, and international expansion will be key drivers of its growth.

With plans to introduce additional diagnostic tests and refine its point-of-care testing solutions, Co-Diagnostics is well-positioned to play a critical role in the future of infectious disease detection. Its ability to combine high-precision PCR technology with a streamlined regulatory approach will likely set new benchmarks in the field of molecular diagnostics.
