The Complex Issue
Patients with recurrent or advanced disease historically have had limited treatment options. Mismatch Repair (MMR) is a molecular mechanism that functions to repair certain errors that occur during DNA replication. Deficiency of this mechanism is most common in endometrial cancer. Confirming MMR status can, therefore, provide valuable information to determine eligibility for anti-PD1 immunotherapy.
90,000 women die globally from endometrial carcinoma each year1
Endometrial Carcinoma accounts for 90% of all Uterine cancers in the US2
The Breakthrough Solution - MMR RxDx Panel
First FDA-approved immunohistochemical companion diagnostic test to identify endometrial cancer patients eligible for immunotherapy
Identification of patients eligible for treatment with JEMPERLI (dostarlimab-gxly) in accordance with the approved therapeutic product labeling
The VENTANA MMR RxDX Panel is intended for the qualitative assessment of DNA mismatch repair proteins in endometrial tumor tissue. Determination of MMR status is based on a panel of four IHC stains scored by Laboratory Medicine Consultants (LMC) pathologists following the FDA-approved protocol. Endometrial cancers determined to be dMMR by Roche Tissue Diagnostics assay may be eligible for treatment with JEMPERLI (dostarlimab-gxly), a programmed death receptor-1 (PD-1) blocking antibody approved by the FDA for the treatment of adult patients with dMMR recurrent or advanced endometrial cancer. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).
