Breakthrough Technology Addresses Industry Challenges
The clinical-stage biopharma company based in Miramar, Florida, announced that its scientists have created new T-cell engagers targeting tissue factor for treating pancreatic cancer and glioblastoma. The therapies were developed using the company's own TRBC platform technology.
This advancement aims to overcome major issues seen with earlier T-cell engagers, such as difficulties in manufacturing, safety concerns in preclinical testing, and weak results against solid tumors.
Promising Preclinical Results Drive Investor Interest
HCW Biologics reported its lead candidate demonstrated 100% survival rates in tumor-bearing mice models, while untreated mice showed zero survival. Non-human primate studies revealed the treatment was well-tolerated at efficacious dose levels without inducing cytokine release syndrome, a serious side effect of current therapies.
Dr. Hing C. Wong, founder and CEO, said, “Our preclinical studies show that our lead second-generation TCE could remarkably shrink well-established tumors.”
Partnership Strategy Positions for Market Entry
According to its press release, the immunotherapy developer plans to collaborate with financially robust corporations for development, aiming to capitalize on a market where T-cell engagers already generate billions in annual sales, despite having only a few approved indications.
