KING OF PRUSSIA, PA — SK Life Science Labs, a subsidiary of SK Biopharmaceuticals Co., Ltd., has announced a major advancement in oncology with the discovery of PVTX-405, a potent IKZF2 molecular glue degrader. Recently published in Nature Communications, the research highlights the potential of this novel agent to amplify the body’s immune response against cancer by targeting immune suppression mechanisms.
“This novel agent represents a significant step toward improved oncology treatments,” stated Ryan Kruger, Ph.D., Chief Scientific Officer at SK Life Science Labs. “By targeting IKZF2, PVTX-405 dramatically reduces immune suppression, allowing the patient’s own immune system to more effectively fight cancer.”
PVTX-405 works by selectively degrading IKZF2, a protein crucial for maintaining regulatory T-cells (Tregs) within the tumor environment. Tregs suppress the immune system, enabling tumors to thrive. By weakening Tregs, PVTX-405 enhances the activity of effector T-cells, triggering a more robust immune response against cancer cells.
Preclinical trials reveal that PVTX-405 offers superior potency, selectivity, and safety compared to previous IKZF2 degraders. Administered as a once-daily oral treatment, it delivers exceptional anti-tumor efficacy, significantly slowing tumor growth and boosting the effectiveness of immune checkpoint inhibitors. Combined, these benefits result in greater tumor regression and extended survival.
“These exciting results reinforce our enthusiasm for partnering with biopharma, research institutions, and investors to fast-track the clinical development of this groundbreaking immunotherapy,” added Dr. Kruger. “This research not only showcases the potential of molecular glue degraders as powerful therapeutic agents but also highlights SK Life Science Labs’ dedication to advancing life-saving treatments.”
PVTX-405 marks a pivotal step forward in the fight against cancer, demonstrating immense promise for improving patient outcomes and transforming modern oncology.
