CareDx and Dovetail Genomics Announce Strategic Partnership to Drive Next Wave of Innovation in Transplant Matching with Cutting-Edge Hi-C Technology

Partnership Includes Early Access Program Enabling HLA Labs to be at the Forefront of Innovative Solutions for Donor-Recipient Matching

 New Data at Annual American Society for Histocompatibility and Immunogenetics Meeting Shows AlloSeq and LinkPrep Technology Enables High-Resolution Genotyping and Haplotyping without Family Studies

BRISBANE, CA, and SCOTTS VALLEY, CA, October 23, 2024 – CareDx, Inc. (Nasdaq: CDNA) — The Transplant Company™ — a leading precision medicine company focused on the discovery, development, and commercialization of healthcare solutions for transplant patients and caregivers, and Dovetail Genomics, a leader in the field of genomic solutions — today announced a strategic partnership to drive the next wave of innovation in HLA genotyping for organ and stem cell transplant matching.

HLA labs will be able to participate in an Early Access Program using CareDx’s NGS-based AlloSeq™ Tx 17 HLA typing solution incorporating Dovetail Genomics’ cutting-edge Hi-C LinkPrep™ technology to achieve high-resolution genotyping and haplotyping without the need for family genotyping studies.  The addition of haplotyping has the potential to improve the likelihood of long-term successful donor-recipient matching.

“This collaboration reflects CareDx’s commitment to innovation in the transplant field, highlighted by our industry first with AlloSeq Tx 17, the first HLA typing solution to cover 17 loci,” said John W. Hanna, CareDx President and CEO. “Through this partnership, HLA labs will gain early access to cutting-edge solutions, positioning them at the forefront of evaluating innovative donor-recipient matching methods.”

CareDx’s AlloSeq Tx 17 is the market-leading NGS-based, HLA typing solution that uses an innovative hybrid-capture workflow to efficiently streamline donor matching studies in HLA typing while providing expanded gene content, beyond 11 classical HLA loci, for more in-depth results.  Dovetail Genomic’s LinkPrep technology introduces a groundbreaking method for generating comprehensive HLA haplotypes. LinkPrep technology is a next-generation rapid Hi-C method that uses short-read sequencing technology to provide direct phasing information from linked long-range reads without relying on any imputation approaches. This enables long distance inter-locus phasing and haplotype determination. Combining AlloSeq Tx with LinkPrep offers researchers the opportunity to evaluate the benefits of high precision and comprehensive HLA haplotypes for donor-recipient matching.

“We believe that Dovetail Genomic’s LinkPrep technology’s unique ability to capture haplotype-aware genetic variation will be a game-changer for applications like HLA testing,” expressed Matt Easterday, Ph.D., J.D., CEO of Dovetail Genomics. “The ability to haplotype through the entire HLA region offers the transplant community an important new tool for optimizing transplant matching.”

The performance of the combined AlloSeq Tx and LinkPrep technology on clinical study samples will be showcased at the 50^th annual American Society for Histocompatibility and Immunogenetics (ASHI) meeting in both a poster session and a CareDx symposium titled “Future of Transplant Solutions: Innovation Across the Pre-and Post-Transplant Journey” on October 23, 2024. HLA labs interested in participating in the early access program are encouraged to reach out to their CareDx representative.
