"Progesterone receptor is the forgotten target", said Carol Lange, PhD, Professor of Medicine at the University of Minnesota and principal investigator of the research presentation. "HR+ breast cancer is driven by two hormones, estrogen and progesterone. While there are over half a dozen approved medicines to block estrogen and estrogen-related signaling, there are no FDA approved medicines in cancer to block progesterone. The data presented shows that blocking progesterone-related signaling via Apristor is not only active alone in tumor models but it also enhances the activity of medicines that either directly or indirectly target estrogen."

The data presented shows that:

Progesterone / progesterone peceptor (PR) is a unique target distinct from estrogen / estrogen receptor

PR is critical for in vitro growth of HR+ breast cancer cells

PR antagonism via Apristor reduces the expression of cancer promoting genes

PR antagonism is synergistic with Cdk4/6 inhibitors and a SERD

"We are encouraged by these new preclinical data, which speak to the important role PR plays in facilitating HR+ breast cancer disease progression," said Deepak Lala, PhD, Chief Technology Officer of Context. "This is the first study to show that PR antagonism is synergistic with new treatment modalities, including Cdk4/6 inhibition. "

About Apristor

Apristor (onapristone extended release) is Context’s wholly owned, first-in-class, orally active extended release formulation of onapristone, a full progesterone receptor antagonist. Progesterone receptor [PR] plays a critical role in facilitating breast cancer disease progression as well as therapeutic resistance to first line antiestrogen and/or Cdk4/6 inhibitor therapies. Apristor is the only full PR antagonist that is being developed to target breast cancer. Apristor has the potential to transform the treatment of breast cancer, through the potent inhibition of PR signaling thereby blocking breast cancer cell proliferation and overcoming resistance to first line antiestrogen and Cdk4/6 inhibitor therapy.

BluePrint reclassifies 85 percent of HER2-positive, and clarifies HER2-equivocal breast cancers in a real-world diagnostic setting1

The first study addressed challenges acknowledged within the Aphinity and ExteNET trials regarding the potential benefits of added HER2-targeted treatment in breast cancer as well as the uncertainty regarding the nature of tumors classified as HER2 "equivocal" by traditional immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). A previous trial showed that BluePrint reclassified almost half of HER2-postive/ER-positive patients identified as HER2-positive using IHC/FISH to the Luminal subtype with differential neoadjuvant treatment response.2,3

In this study, Agendia scientists analyzed HER2-positive and HER2-equivocal cancers (as defined by the 2013 CAP Guidelines), comparing IHC/FISH status from pathology results to BluePrint molecular subtype in a real-world diagnostic setting. In IHC/FISH HER2-amplified tumors, BluePrint reclassified 85 percent to non-HER2 molecular subtypes, mostly Luminal-type for ER-positive tumors and Basal-type for ER-negative tumors. BluePrint also classified all HER2-equivocal tumors to non-HER2 subtypes, Luminal and Basal, which could not be derived from IHC/FISH. No HER2 "equivocal" cancers by IHC/FISH displayed a HER2-driven genotype.

Dr. William Audeh, chief medical officer at Agendia, said: "The findings from this real-world study indicate that additional therapeutic options should be considered for some women with clinically HER2-positive cancers with genomic profiles of Luminal or Basal subtypes. These data also provide further precision to clarify the clinical uncertainty regarding the HER2 "equivocal" subtype. This study further reinforces the critical role BluePrint plays in helping to inform more personalized treatment decisions by adding to a growing body of evidence demonstrating the importance of tumor molecular subtyping in breast cancer."

MammaPrint identifies 46 percent of patients under 50 years of age with an intermediate recurrence score as Low Risk4

The second study reevaluated data from the PROMIS (PRospective Study Of MammaPrint in Patients With an Intermediate Recurrence Score) trial using the same subgroup analyses that was used in the TAILORx trial. It aimed to establish greater certainty regarding the benefits of chemotherapy among female breast cancer patients under 50 with an intermediate recurrence score from the 21-gene assay (RS 18-30). The new analyses found 46 percent of these women had a low genomic risk of recurrence as assessed by MammaPrint and were unlikely to benefit from chemotherapy. Researchers also found that in the MINDACT trial, MammaPrint patients younger than age 45 and between the ages of 45-55 who also have a Low Risk result had a favorable 5-year distant metastasis-free survival of 95-98 percent in both clinically low and high risk groups.

Dr. Hatem Soliman, medical director of clinical trials at the Moffitt Cancer Center and lead study author, said: "The TAILORx trial raised important questions about the benefits of chemotherapy in women under 50, so we were pleased to see that our new subgroup analysis of the PROMIS data, using the same approach as seen in TAILORx, showed that MammaPrint provides greater certainty regarding which women are unlikely to benefit from chemotherapy. Patient quality of life, in the short-term and longer-term, is paramount, so the role of MammaPrint in signaling where physicians can safely de-escalate their patients’ treatments, and thus side effects, is important."

About MammaPrint

MammaPrint is an in vitro diagnostic medical device, performed as a testing service in a central laboratory, using the 70-gene expression profile of breast cancer tissue samples to assess a patient’s risk for distant metastasis. The device is FDA-cleared and CE-marked, enabling use in the European Union. MammaPrint is indicated for use by physicians as a prognostic marker only, along with other clinical-pathological factors. It is not intended to determine the outcome of disease, nor to suggest or infer an individual patient’s response to therapy. MammaPrint is the only test of its kind recommended for lymph node-negative and lymph node-positive patients by both the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) and National Comprehensive Cancer Network (NCCN). The test is also recommended by many other national and international clinical practice guidelines.
