Effective March 1, 2023, Blue Shield of California now provides commercial coverage of Signatera for plan members diagnosed with any solid tumors. Specifically, the policy describes tumor-informed ctDNA testing with Signatera as medically necessary for patients with stage I-IV cancer to provide information for (1) adjuvant or targeted therapy; and/or (2) monitoring for relapse or progression, including but not limited to the use of immunotherapy.

In addition, effective January 1, 2023, Blue Cross and Blue Shield of Louisiana is providing coverage of serial testing with Signatera for plan members diagnosed with colorectal and muscle invasive bladder cancer and for pan-cancer immunotherapy monitoring.

"Following the recent breast cancer coverage decision by Medicare, achieving our first commercial coverage policies for Signatera – including one that encompasses pan-cancer coverage – is another major milestone for Natera and the patients who will now have enhanced access to tumor-informed ctDNA testing," said John Fesko, chief business officer. "These developments underscore the medical necessity of Signatera to inform critical treatment decisions and detect recurrence earlier."

Data supporting the clinical validity and utility of Signatera has been published in approximately 40 peer-reviewed publications, including validation across multiple cancer types to detect recurrence earlier than standard diagnostic tools1,2 and to improve the assessment of treatment response in conjunction with imaging.3

About Signatera

Signatera is a custom-built circulating tumor DNA (ctDNA) test for treatment monitoring and molecular residual disease (MRD) assessment in patients previously diagnosed with cancer. The test is available for both clinical and research use, and has been granted three Breakthrough Device Designations by the FDA for multiple cancer types and indications. The Signatera test is personalized and tumor-informed, providing each individual with a customized blood test tailored to fit the unique signature of clonal mutations found in that individual’s tumor. Signatera is intended to detect and quantify cancer left in the body, at levels down to a single tumor molecule in a tube of blood, to identify recurrence earlier and to help optimize treatment decisions.

On March 2, 2023 Prostate Cancer Foundation reported that Immunotherapies have successfully treated many types of cancer with the exception of advanced prostate cancer that has become resistant to treatment, known as metastatic castration-resistant prostate cancer (mCRPC) (Press release, Prostate Cancer Foundation, MAR 2, 2023, View Source [SID1234628102]). New findings from a Prostate Cancer Foundation (PCF)-funded investigator reveal the mechanism by which prostate cancer cells reprogram the immune system to promote rather than suppress cancer, as well as a promising new combination therapy that could prevent them from developing this ability.

The research led by 2016 Izzy Englander – PCF Challenge Award recipient Akash Patnaik, MD, PhD, MMSc, and his team at the University of Chicago was recently published in the peer-reviewed journal Clinical Cancer Research.

"These findings represent an exciting new opportunity to prevent prostate cancer cells from evading the immune system and a promising combination therapy for metastatic castration-resistant prostate cancer," said Howard R. Soule, PhD, Executive Vice President and Chief Science Officer of the Prostate Cancer Foundation. "PCF commends Dr. Patnaik and the research team on their achievement and proudly supports their work to bring us closer to our mission to eliminate death and suffering from prostate cancer."

Researchers found that by recruiting abnormal tumor-associated macrophages (TAM) that express PD-1 into the tumor microenvironment, the immune system promotes the growth of prostate cancer.

Androgen deprivation therapy (ADT) and chemotherapy are first-line treatment options for metastatic prostate cancer. However, patients often relapse and the disease advances. Nearly 35,000 men in the U.S. are projected to die of prostate cancer in 2023.

Approximately 50% to 75% of mCRPC patients have a mutation in the tumor suppressor gene PTEN which drives the PI3K tumor growth and survival pathway; in patients with PTEN-mutated tumors, the normal anti-tumor immune response is often suppressed. Alterations of the PTEN/PI3K pathway are known drivers of advanced prostate cancer. Clinical trials of single drugs to target this pathway and combinations of PI3K inhibitors and ADT have shown limited benefit in patients with mCRPC.

Patnaik and his team performed a series of experiments using PTEN-mutated mouse models. They found that following treatment with a combination of ADT and copanlisib, a PI3K inhibitor, PD-1-expressing immunosuppressive TAM blocked the anti-cancer immunity mediated by macrophages; the cancer cells forced the macrophages into tumor-promoting mode by binding to the protein PD-1 on their surface. The researchers hypothesized that adding a third drug to block PD-1 would unleash the ability of the macrophages to kill the cancer. The triple combination of PD-1 checkpoint immunotherapy plus ADT hormone therapy plus a PI3K inhibitor yielded a response rate 60% greater among treated mice than among untreated control mice. These data suggest that the three-drug approach is needed to overcome treatment resistance in PTEN-mutated prostate cancer.

As part of the PCF Challenge Award, a phase 1b clinical trial will be conducted to test the safety and efficacy of copanlisib in combination with an anti-PD-1 drug in patients with PTEN-deficient mCRPC. If successful, the research could result in a new precision immunotherapy regimen for these patients.
