Business Overview and History

CareDx Inc (CDNA) is a leading precision medicine company focused on transforming the lives of transplant patients and caregivers through its innovative diagnostic solutions, patient and digital tools, and high-quality products. With a relentless dedication to advancing the field of transplantation, CareDx has established itself as a trailblazer, continuously pushing the boundaries of what is possible in this critical area of healthcare.

CareDx was originally incorporated in Delaware in December 1998 under the name Hippocratic Engineering, Inc. The company underwent several name changes over the years, including BioCardia, Inc. in April 1999, Expression Diagnostics, Inc. in June 2002, and XDx, Inc. in July 2007, before finally settling on CareDx, Inc. in March 2014. Founded with the mission to develop diagnostic solutions for transplant patients, CareDx has made significant investments over the past 25 years to build a comprehensive portfolio of testing services, products, and patient and digital solutions spanning the pre- and post-transplant patient journey.

A key milestone in the company's history was the launch of its first product, AlloMap Heart, in 2005. This innovative gene expression profiling test was designed to aid in identifying heart transplant recipients with a low probability of moderate-to-severe acute cellular rejection. Building on this success, CareDx continued to expand its offerings, launching AlloSure Kidney in 2017, a donor-derived cell-free DNA solution for kidney transplant patients.

Throughout its development, CareDx has faced challenges common to many diagnostic companies, including gaining acceptance from clinicians, obtaining reimbursement coverage from payers, and navigating the complex regulatory environment. The company has addressed these challenges by focusing on generating clinical evidence to demonstrate the value of its solutions, actively working to expand payer coverage, and maintaining strict compliance with applicable laws and regulations.

At the core of CareDx's mission is the development and commercialization of clinically differentiated, high-value diagnostic solutions for transplant patients and caregivers. The company's product portfolio includes a range of cutting-edge testing services, innovative products, and patient and digital solutions that span the pre- and post-transplant patient journey.

CareDx's flagship testing services include AlloSure Kidney, a donor-derived cell-free DNA (dd-cfDNA) solution for kidney transplant patients; AlloMap Heart, a gene expression profiling solution for heart transplant patients; AlloSure Heart, a dd-cfDNA solution for heart transplant patients; and AlloSure Lung, a dd-cfDNA solution for lung transplant patients. These solutions have been instrumental in transforming the way transplant recipients are monitored, enabling early detection of rejection and guiding clinicians in their treatment decisions.

In addition to its testing services, CareDx offers a diverse range of high-quality products that facilitate successful transplants, including HLA typing kits and IVD monitoring assays for solid organ and stem cell transplant recipients. The company's patient and digital solutions, such as its transplant pharmacy, software tools, and remote patient monitoring services, further complement its offerings, providing comprehensive support throughout the transplant journey.

CareDx's commitment to innovation is evident in its robust research and development pipeline, which includes the development of new testing solutions, such as AlloSure Heart for pediatric patients and AlloSure Kidney for simultaneous pancreas and kidney transplantation. The company's dedication to evidence generation has also led to the publication of numerous studies in peer-reviewed journals, bolstering the clinical utility and adoption of its solutions.
