Decipher GRID Signature Predicts Benefit from Chemotherapy in Men Diagnosed with Metastatic Prostate CancerSAN DIEGO, Feb. 13, 2020 -- (Healthcare Sales & Marketing Network) -- Decipher Biosciences, a commercial-stage precision oncology company committed to improving patient care, initially focused on urologic cancers, today announced that a Decipher GRID molecular subtyping signature, studied in patients from the phase III, randomized controlled trial, CHAARTED, successfully predicted which prostate cancer patients diagnosed with metastatic hormone sensitive prostate cancer (mHSPC) benefited from the addition of chemotherapy to androgen deprivation hormone therapy.
The investigators found that patients with the luminal B molecular subtype derived the most benefit from the addition of taxane chemotherapy, with a 55% reduction in risk of death, adding 22 months of median survival. In the trial population tested, 48% of the patients were found to have the luminal B molecular subtype. Patients with the remaining molecular subtypes received no significant survival benefit from the addition of taxane chemotherapy.
"Identifying which patients will benefit from chemotherapy is one of the most important clinical questions in the management of metastatic prostate cancer," said Christopher Sweeney, MBBS, a medical oncologist and professor of medicine at Dana-Farber Cancer Institute. "The ability to identify these patients at diagnosis is a very important step towards improving patient outcomes and accelerating the inclusion of novel drugs into the standard of care."
Results will be presented February 13, 2020, at the Genitourinary Cancer Symposium Oral Abstract A session:

Our Decipher Prostate RP genomic tests are currently marketed and sold to physicians treating prostate cancer through the adjuvant therapy decision for patients who have received a radical prostatectomy and are being considered for additional therapy. The test reports the Decipher score which prognosticates a patient's risk of metastasis within five years. The Decipher score is intended to improve clinical decision making by helping physicians identify patients who have high risk of metastasis and require more intensive therapy or who have low risk of metastasis and can reduce treatment intensity. We have obtained Medicare coverage for patients, including for those who have been diagnosed with adverse pathology following a radical prostatectomy and are being considered for additional therapy. Decipher Prostate RP can help guide physicians to better select the appropriate therapy for a specific patient, which in turn can result in improved patient outcomes.
Decipher GRID is our Real-World Evidence genomic database containing over 75,000 urologic cancer transcriptomes matched to patient demographics and including clinical trial outcome data, which is one of the largest and well-annotated urologic cancer genomic databases in the world. Decipher GRID's patient data is derived from decades of clinical trials and is continuously being expanded through a growing community of pharmaceutical and academic partners. The diversity of clinical sample inputs, ranging from global clinical trials to standard-of-care practices in urban, suburban and rural centers, help provide a comprehensive view of the future and current states of the practice of urologic cancer care. We leverage Decipher GRID outputs to partner with investigators and pharmaceutical companies to help identify patient populations that might benefit from earlier use of proprietary drugs or combination therapeutic strategies, or that are prime candidates for novel therapeutics. Decipher GRID is our proprietary engine that drives product development for us, and informs the product development efforts for our pharmaceutical partners.
