Evidence

Spartan's molecular diagnostic test is based on 13 years of R&D and decades of scientific research. The following studies support Spartan's technology.

The Pharmacogenomics: Cost-effectiveness of CYP2C19-guided antiplatelet therapy in patients with acute coronary syndrome and percutaneous coronary intervention informed by real-world data

Medical
  • A cost-effectiveness analysis (CEA) was performed using real-world data from acute coronary syndrome (ACS) patients receiving percutaneous coronary intervention (PCI)
  • The CEA compared three antiplatelet treatment strategies: (1) universal clopidogrel, (2) universal ticagrelor, or (3) genotype-guided therapy
  • Only genotype-guided therapy resulted in an improvement in quality-adjusted life years (QALYs) and was cost-effective

American Heart Association: Prospective CYP2C19 genotyping to guide antiplatelet therapy following percutaneous coronary intervention

Medical
  • Spartan's rapid CYP2C19 genotyping test was implemented at the University of Pennsylvania Health System for patients receiving percutaneous coronary intervention (PCI)
  • 28% of patients carried loss-of-function CYP2C19 mutations
  • Prasugrel or ticagrelor were used in 30% of the genotyped group vs. 21% of the usual care group who were not genotyped

Spartan knows of no other financial interests. Spartan knows of no significant risks or safety concerns associated with the use described in this publication.

The Lancet: Point-of-care genetic testing for personalisation of antiplatelet treatment (RAPID GENE): a prospective, randomised, proof-of-concept trial

Medical
  • Rapid genetic testing after PCI can be effectively done at the bedside to identify CYP2C19*2 LOF allele carriers
  • This prospective, randomized 200-patient study reported that tailored, genotype-guided treatment of CYP2C19*2 carriers can reduce high on-treatment platelet reactivity, which is commonly associated with increased risk for major adverse cardiovascular events
  • This study is the first reported use of an FDA-cleared, rapid CYP2C19 genetic test, and offers a novel solution to overcome limitations in pharmacogenomics

*The Spartan CYP2C19 test is not cleared for point-of-care use in the US.

New England Journal of Medicine: A Genotype-Guided Strategy for Oral P2Y12 Inhibitors in Primary PCI

Medical
  • This randomized, prospective trial of 2,488 patients undergoing primary PCI with stent implantation assessed the use of a genotype-guided approach to oral P2Y12 inhibitor selection
  • This study showed that a genotype-guided approach to therapy was noninferior to standard treatment with ticagrelor or prasugrel with respect to thrombotic events, and resulted in a lower incidence of bleeding
  • Considering that ticagrelor/prasugrel cost 10-20X more than generic clopidogrel, CYP2C19 genotyping can significantly lower healthcare costs

Spartan Bioscience: On-site Legionella qPCR test helps identify faulty chemical dispense valve

Environmental
  • On-site qPCR enabled the client to identify low-level Legionella contamination and fix it 17 days faster than if they relied on culture testing alone.
