Clinical comparison of a NGS-based approach vs. conventional testing methods*

PathoQuest has completed a proof of concept clinical study which compared the ability of a NGS-based testing approach identify pathogens in patients with suspected infections versus the use of conventional testing methodologies was conducted at two prominent medical centers in France. This study:

  • A total of 101 patients were enrolled in the study.
  • All patients enrolled were immunocompromised and 23% of the patients were neutropenic.
  • The study cohort included the following reasons of immunosuppression:

– Anti-cancer chemotherapy

– Immunosuppressive treatment following solid organ transplantation

– Stem cell transplant recipients

– Primitive immunodeficiency

– Other causes of immunosuppression

  • The study compared PathoQuest’s next generation sequencing (NGS) based testing approach to standard testing methodologies (blood cultures and targeted PCR testing).
  • Testing results from both arms of the study were medically adjudicated by a panel of clinical experts in order to confirm that the pathogens identified were likely to be associated with the patient’s infection-related symptoms and clinical presentation.

The results of this study have been recently published in the peer-reviewed journal Clinical Microbiology and Infection, an official publication of ESCMID. Link to publication abstract.
