Medicare Administrative Contractor CGS Administrators, LLC (CGS) has issued a final Local Coverage Decision (LCD) providing favorable coverage for IsoPSA. IsoPSA will now be covered for the millions of men enrolled in Medicare nationwide and provide clearer information to patients and their doctors evaluating whether prostate biopsy is appropriate for them. Medicare covers 60 million men and women beneficiaries nationwide. The effective date for the LCD is November 20, 2022.

The AMA has awarded a Proprietary Laboratory Analysis code (CPT-PLA) for IsoPSA, thus providing the mechanism for payment required by payors to uniquely track and reimburse Cleveland Diagnostics for IsoPSA. This CPT-PLA code (0359U) will be effective January 1, 2023.

"We are very pleased to receive Medicare coverage and AMA coding for our IsoPSA test," said Arnon Chait, PhD, Chief Executive Officer of Cleveland Diagnostics. "These coverage and coding determinations are highly significant for physicians and patients, as they will expand access to IsoPSA, a test with multiple clinical indications related to prostate cancer, enabling better informed treatment decisions."

Up to 75% of the prostate biopsies performed in the US are negative for high-grade disease, placing undue burdens on patients, clinicians, and the healthcare system. Unlike the current standard of care in prostate cancer testing, prostate-specific antigen (PSA), which measures merely the concentration of PSA circulating in the blood, IsoPSA interrogates structural variants of PSA, providing clinicians and patients with greater clarity in identifying men who would benefit from prostate biopsy and who would not. In large, prospective multicenter studies of men scheduled for biopsy, IsoPSA demonstrated superior diagnostic accuracy compared to PSA in identifying patients with high-grade cancer. A large real-world clinical utility study has also shown that IsoPSA can reduce the number of unnecessary prostate biopsies by up to 55%.

The patented technology is part of an exclusive license Palleon has with Stanford University and originated in the laboratory of Carolyn Bertozzi, an inventor on the patent, and a scientific co-founder of Palleon Pharmaceuticals. Dr. Bertozzi was recently awarded the 2022 Nobel Prize for Chemistry for the invention of bioorthogonal chemistry, a technology which enabled the foundational science for Palleon’s platform.

"It is thrilling to see Palleon’s pioneering EAGLE platform reach this important milestone," said Dr. Bertozzi. "Therapeutic removal of sialic acid from cells in the tumor microenvironment, as this patent describes, has shown promising potential in generating an immune antitumor response in pre-clinical studies. This glyco-immunology approach could deliver meaningful benefits for patients who don’t respond to today’s immuno-oncology treatments."

The EAGLE platform enables the development of first-in-class therapies that strip sialic acids from both immune cells and cancer cells, restoring innate and adaptive antitumor immunity. This patent covers the use in cancer of tumor-targeted antibodies conjugated to sialidase, an enzyme that cleaves sialic acid.

"This patent provides important additional intellectual property coverage for an approach that, we believe, is key to expanding the promise of immunotherapy to millions of patients, especially to those patients with immune suppression who do not respond to currently approved immunotherapy agents," said Jim Broderick, M.D., Chief Executive Officer and founder of Palleon. "With this patent solidified, we are in a strong position to continue development of an entirely new class of investigational therapies within our rich, clinical-stage pipeline."

"We are excited by the promise shown by GNUV205," said Sungho Han, Ph.D., founder and CEO of Genuv. "Treatments targeting IL-2 are uniquely powerful, but have typically been plagued by systemic toxicity issues. Our strategy using a ‘no-alpha but attenuated beta gamma’ IL-2 variant fused with a unique anti-PD-1 via Genuv’s proprietary hetero Fc technology shows stronger binding affinity in the tumor microenvironment compared to marketed treatments Proleukine, Keytruda and Opdivo without Treg cell expansion."

Jenny Choih, Ph.D., K.M.D., Genuv’s director of clinical development and president of its U.S. subsidiary, said, "The preclinical results we will be sharing at the Immuno-Oncology Summit demonstrate conclusively how our drug candidate GNUV205 overcomes the limitations seen with many immune checkpoint inhibitors as well as IL-2 treatment. Many patients become refractory and need additional treatment options. In addition, for many patients, treatment can be limited by the severe systemic toxicities associated with traditional IL-2 treatments."

Genuv recently opened a U.S. subsidiary in Cambridge, MA to facilitate partnering activities and speed clinical development of GNUV205 and other immuno-oncology drug candidates.

Dr. Choih presented the poster with preclinical data on GNUV205. Details of the presentations are shown below.
