Invivoscribe® Receives FDA Approval for the LeukoStrat® CDx FLT3 Mutation Assay Companion Diagnostic Test for the Selection of Patients for Rydapt® and is the First Companion Diagnostic for AML

SAN DIEGO, April 28, 2017 -- Invivoscribe^® Technologies Inc., a global company with more than 20 years of experience providing clonality and biomarker test solutions for the fields of oncology, personalized molecular diagnostics^® and personalized molecular medicine^®, today announces the premarket approval of LeukoStrat^® CDx FLT3 Mutation Assay.  Due to current labeling for the FDA approved test, FLT3 mutation testing with LeukoStrat^® CDx FLT3 Mutation Assay is exclusively performed by The Laboratory for Personalized Molecular Medicine, a subsidiary of Invivoscribe Technologies, Inc., which has gained FDA approval for its FLT3 test as a companion diagnostic for the Novartis drug Rydapt® in newly diagnosed FLT3+ AML.

Under terms of a previously announced agreement with Thermo Fisher, Invivoscribe will also seek FDA approval of the LeukoStrat^® CDx FLT3 Mutation Assay that will allow the sale of kits to other laboratories. The Invivoscribe LeukoStrat^® CDx FLT3 Mutation Assay is a signal ratio assay that identifies both internal tandem duplication (ITD) and tyrosine kinase domain (TKD) mutations, and identifies even large ITD mutations, which are missed using many current NGS-based assays.

FLT3 somatic variants are among the most common driver mutations with the strongest effects on the overall survival in acute myeloid leukemia¹ (AML), the most deadly form of leukemia, which is diagnosed in about 20,000 new patients each year in the U.S. and has only a 26.6 percent five-year survival rate². Invivoscribe, working under a companion diagnostic agreement with Novartis, developed this companion diagnostic for FLT3 successfully achieving FDA regulatory approval. The Invivoscribe LeukoStrat^® CDx FLT3 Mutation Assay is the first companion diagnostic for AML.

"This test approval will be of substantial benefit to patients afflicted with AML and is a critical tool for healthcare providers to identify the most appropriate treatment for newly diagnosed FLT3-mutated AML patients, furthering the promise of personalized molecular diagnostics and precision medicine,” said Dr. Jeffrey Miller, CSO & CEO of Invivoscribe. "And, as has been previously noted by others³, there is a need for an internationally standardized FLT3 mutation assay and this companion diagnostic is a step toward fulfilling that need."
