SpeeDx Pty, Ltd. announced an agreement with Cepheid to manufacture their market-leading ResistancePlus® tests for use on the GeneXpert System. The first test in Cepheid’s FleXible Cartridge programme, planned for launch early 2019, is ResistancePlus® MG, detecting the sexually transmitted infection (STI) Mycoplasma genitalium (Mgen) and markers associated with azithromycin resistance.

ResistancePlus MG will be the first assay available through the Cepheid FleXible for GeneXpert program.
“The availability of ResistancePlus MG in a FleXible cartridge that runs on the GeneXpert System is a compelling and exciting extension for us,” said Colin Denver, CEO of SpeeDx. “Patients are already benefiting from Resistance Guided Therapy with our central lab tests. Now clinicians can receive resistance information even faster, to support antimicrobial stewardship and more effective antibiotic treatment decisions.”
“Our new FleXible Cartridge program allows Trusted Reagent Manufacturers to develop targeted molecular tests using Cepheid’s easy-to use-cartridge.” said David H. Persing, M.D., Ph.D., Cepheid's Chief Medical and Technology Officer. “With a global installed base of nearly 22,000 GeneXpert Systems, this technology could potentially be applied in multiple settings in which actionable treatment information is needed quickly.”
Management guidelines for Mgen infection include resistance testing1-3 in response to rising rates of macrolide resistance observed with Mgen detection-only or empiric Mgen treatment.4-6 ResistancePlus® MG supports Mgen management guidelines and allows for Resistance Guided Therapy, which is clinically proven to improve cure rates by providing clinicians with much needed information to guide antibiotic treatment.3
M. genitalium can cause symptoms such as urethritis, cervicitis, endometritis and pelvic inflammatory disease. In recent studies, it has been found to have a higher prevalence than gonorrhea. 7 Like gonorrhea, M. genitalium is also evolving into a so-called STI superbug that is becoming resistant to many antibiotic treatments, leading to exceedingly difficult-to-treat infections and threatening global public health.8
Macrolide antibiotics, specifically azithromycin, are the first-line treatment for the rapidly growing problem of M. genitalium STIs, but resistance to these antibiotics has increased up to 50% in several countries.4-6 Due to this growing antibiotic resistance problem, several global STI Management Guidelines on Mgen Infections recommend complementing the use of molecular testing to detect M. genitalium with an assay capable of detecting macrolide resistance-associated mutations.1-3
Currently, there is no FDA-cleared molecular diagnostic test for the detection of M. genitalium in the U.S. The SpeeDx ResistancePlus® MG assay is CE marked for sale in Europe and TGA approved for sale in Australia. The test provides valuable detection and antibiotic resistance information to clinicians in a rapid time frame. Timely detection of antibiotic resistant infections enables Resistance Guided Therapy for better treatment of the disease for patients, lessening the potential for spreading among vulnerable populations and combating antibiotic resistance.
Founded in 2009, SpeeDx is an Australian-based private company with offices in London and the US, and distributors across Europe. SpeeDx specializes in molecular diagnostic solutions that go beyond simple detection to offer comprehensive information for improved patient management. Innovative real-time polymerase chain reaction (qPCR) technology has driven market-leading multiplex detection and priming strategies.
