The target CTLA-4 is the first clinically validated immune checkpoint and the first antibody drug (ipilimumab) approved for marketing in 2011. The price of one dose in the first prescription issued in China is￥28,000.

IMM27M is an IgG1 antibody against CTLA-4. It has been genetically engineered to enhance ADCC activity. Comparing to the similar drug Ipilimumab, its efficacy in animals is much better at the same dosage (see the fig.). And IMM27M can remove the tumor completely at as low as 0.3 mg/kg.

Dr. Tian, Wenzhi, the founder, chairman and CEO of ImmuneOnco, said: "We are very pleased that our next-generation CTLA-4 antibody project, IMM27M, completed the first patient enrollment and dosing. Multiple repeatable in vivo studies have demonstrated that IMM27M has strong anti-tumor activity and can be combined with various drugs in the company’s pipeline. The combination therapy of CTLA-4 with PD1/PD-L1 has been proven to have clear clinical synergy, and indeed BMS’ ipilimumab combined with Opdivo has been approved by the FDA for multiple indications including melanoma, colorectal cancer, renal cell carcinoma, hepatocellular carcinoma, and non-small cell lung cancer.We believe that IMM27M have great value for clinical development."

"We will continue to advance the research of the IMM27M project to bring good news to cancer patients."

On June 15, 2022 Coya Therapeutics, Inc. (Coya), a clinical-stage biotechnology company developing multiple first-in-class and best-in-class approaches that enhance regulatory T cells (Tregs) function in vivo, including autologous and allogeneic Treg-derived exosome therapeutics, and novel biologics, reported the execution of an option agreement for exclusive worldwide rights to a novel and proprietary technology platform enabling exosome engineering from Carnegie Mellon University (Press release, Coya Therapeutics, JUN 15, 2022, View Source [SID1234635089]).

The exclusive option agreement involves the intellectual property rights to the research, development, and manufacturing of exosome-polymer hybrids (EPHs), a tether-based exosome functionalization strategy that enables Treg exosomes to be homed to proteins of interest, while delivering select payloads into those targeted cells.

"This collaboration with Carnegie Mellon University further solidifies Coya’s thought leadership in the global exosome therapeutics field, beyond Treg-derived exosomes alone," stated Howard Berman, Ph.D., CEO of Coya Therapeutics. "Nanoengineering exosomes with such manufacturing efficiency to produce EPHs that can be customized to any surface protein, delivering growth factors or drugs, while enhancing cellular uptake and bioactivity is the future of targeted therapies."

Previously, most techniques to modify exosomes relied on complex molecular biology tools or degradation of exosomes innate functionality. EPHs overcome many of these limitations by creating a method that rapidly and efficiently modifies exosomes with a DNA-cholesterol tether. The technology leverages single stranded synthetic DNA with attached cholesterol, binding a complementary strand of DNA linked to a bioactive agent. As a result, a number of different types of cargos can be readily attached to the exosome surface while also tethering immune modulating cargoes inside the exosome.

"The next step of our development program will be to leverage EPHs to validate functional activity of our Treg-derived exosomes that home in and bind to high profile protein targets that drive specific disease processes. Additionally, these EPHs will be loaded with identified payloads to enhance efficacy," stated Adrian Hepner, M.D., Ph.D., Chief Medical Officer of Coya Therapeutics.

Drs. Subha Das and Phil Campbell of Carnegie Mellon University added: "Targeted Treg exosome therapeutics that are directed to epitopes and proteins of interest, while delivering potent growth factors, drugs or other cargo, represent an innovative platform that is advantageous on many fronts relative to other CAR Treg directed platforms. We are excited and committed in joining this collaboration with Coya Therapeutics."

On June 15, 2022 Gnubiotics Sciences, a biotech company pioneering immunomodulatory glycopeptides, reported an agreement with the University of Pennsylvania to explore combining CAR-T therapy with Gnubiotics’ GLAAD technology to enhance efficacy in solid tumors through company-sponsored pre-clinical research studies in the laboratory of Avery Posey, PhD, an assistant professor of Systems Pharmacology and Translational Therapeutics at the Perelman School of Medicine at Penn (Press release, Gnubiotics Sciences, JUN 15, 2022, View Source [SID1234616041]). Gnubiotics presented compelling data recently at the 2022 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) annual meeting showing the effect of its glycopeptides platform in driving directed and robust T-cell immune responses against PD-1 resistant solid tumors in a colorectal cancer mouse model.

While CAR-T has been effective in treating certain blood cancers, numerous studies have shown that many solid tumors do not respond well to CAR-T therapy. "We are excited about the promise of combining CAR-T with glycopeptide strategies like our GLAAD platform which will hopefully lead to the application of new modalities for patients left with few alternative treatments," stated Yemi Adesokan, Ph.D., Gnubiotics’s Chief Executive Officer.

About GLAAD

Glycopeptides are the foundation of Gnubiotics’ GLAAD molecules. GLAAD relies on glycopeptides as providers of antigenicity and adjuvanticity to the immune system. Gnubiotics’ GLAAD candidates are made of a range of glycans uniquely bound to peptides and can act directly on immune cells and modulate the microbiome. Combined, these modes of action influence the immune system responses which opens new ways to address areas where the immune system plays a role, including oncology, inflammatory and infectious diseases.
