These are the first in a series of presentations scheduled through the end of the year sharing advances to SK Biopharmaceutical's targeted protein degradation (TPD) pipeline

SEOUL, South Korea and KING OF PRUSSIA, Pa., Sept. 27, 2023 /PRNewswire/ -- SK Biopharmaceuticals, a global biotech focused on the research, development and commercialization of treatments for disorders of the central nervous system (CNS) and oncology, and its U.S. R&D subsidiary, Proteovant Therapeutics, today announced they will present data on the discovery and characterization of a selective IKZF2 molecular glue degrader with best-in-class potential, and on MOPED™, a novel platform for the discovery of molecular glues, at the 20^th Annual Discovery on Target Conference being held in Boston, September 25-28, 2023.

These presentations are the first in a series in which the companies will unveil exciting results from its targeted protein degradation (TPD) studies and MOPED^TM Molecular Glue Screening Platform. TPD harnesses the body's natural protein disposal system and offers the potential to develop new medicines targeting historically difficult-to-drug proteins that play an important role in causing serious diseases. SK Biopharmaceuticals and Proteovant Therapeutics are discovering and developing potential best-in-class and first-in-class degraders to engage previously undruggable targets.

"We are excited to share new data on our IKZF2 molecular glue degrader that demonstrates the potential to combine with immune checkpoint therapies for the treatment of cancer," said Donghoon Lee, President and CEO of SK Biopharmaceuticals and SK Life Science. "We are also pleased to present data showing how our MOPED™ platform can help find molecular glues with the potential to destroy malfunctioning proteins and kill cancer cells or inhibit their growth."

Discovery on Target Meeting Presentations:

• Title: MOPED™: A Novel Platform for the Discovery of Molecular Glues 
• Presenter: Corey Strickland, Ph.D.
• Date/Time: Wednesday, September 27; 9:30 - 10:00 AM
• Title: Discovery and Characterization of an IKZF2 Selective Molecular Glue Degrader with Best-in-Class Potential
• Presenter: Courtney G. Havens, Ph.D.
• Date/Time: Thursday, September 28; 2:50 - 3:20 PM

About Proteovant Therapeutics

Proteovant Therapeutics exploits the ubiquitin-protease system (UPS) to discover and develop transformative medicines for the treatment of patients with life-altering diseases. Protein degradation harnesses the human body's innate cellular machinery by way of the UPS to identify and mark disease causing proteins for destruction. This promising approach provides the opportunity to target proteins of interest, many of which were previously considered undruggable. Proteovant integrates its AI enabled target ID platform, degrader drug hunting expertise, and MOPED™ molecular glue screening platform to advance novel protein degraders. As of August 11, 2023, Proteovant Therapeutics is part of SK Biopharmaceuticals.
