Genuv Unveils GNUV205, a Bifunctional Fusion Protein That Potently Regresses Tumor Growth Without Toxicity

• Poster on GNUV205 presented at the Immuno-Oncology Summit
• GNUV205 demonstrates Genuv�s “no-alpha/attenuated beta fused with anti-PD-1” strategy to reduce toxicity

SEOUL, Republic of Korea & CAMBRIDGE, Mass.–(BUSINESS WIRE)–Genuv Inc., a clinical-stage biotechnology company focused on innovative drug discovery for degenerative central nervous system diseases and advanced immuno-oncology therapeutics, unveiled a new drug candidate, GNUV205, a fusion of engineered IL2 and anti-PD-1 antibody that advances immuno-oncology science. The drug candidate, for unspecified solid tumors, shows powerful anti-tumor activity without the toxicity typically associated with current IL-2 treatments.

“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.

Immuno-Oncology Summit: Oct. 12-14, Boston, MA

Poster number: P09

Title: GNUV205, a ‘No ? and Attenuated IL-2’ Variant Fused with Novel Anti-PD-1, Potently Regresses Tumor Growth Without Toxicity via Selective Targeting to PD-1+ Teff Cell in Tumor Microenvironments

Presenter: Jenny Choih, Ph.D., K.M.D.

About GNUV205

GNUV205 is a fusion protein designed to solve the chronic problems of immune checkpoint inhibitors and IL-2 therapy. GNUV205 is cross-reactive to mouse and human PD-1 and demonstrates stronger affinity for PD-1 in the low-pH tumor microenvironment. Developed with our proprietary NuvoFc™ heterodimeric antibody platform, GNUV205 overcomes the limitations of current IL-2 therapy by eliminating interactions with Treg cells and with selective but attenuated IL-2 signaling in Teff cells. The human-mouse cross reactivity of GNUV205 predicts strong efficacy and low toxicity in human trials, positioning the drug candidate as a novel therapeutic option that overcomes the traditional limitations of anti-PD-1 and IL-2 therapies.
