ABL Bio Receives IND Approval for Phase 1 Clinical Trial of ABL501, an anti-LAG-3/PD-L1 Bispecific Antibody

ABL501 uses Grabody-I platform technology to simultaneously block PD-L1 and LAG-3-mediated T cell inhibition. Preclinical results demonstrate a synergistic increase of T cell activation that is higher than the enhancements induced by combination of anti-PD-L1 and LAG-3. ABL501 also showed a good safety profile in monkeys. ABL501 uses Grabody-I platform technology to simultaneously block PD-L1 and LAG-3-mediated T cell inhibition.

Preclinical results demonstrate a synergistic increase of T cell activation that is higher than the enhancements induced by combination of anti-PD-L1 and LAG-3. ABL501 also showed a good safety profile in monkeys.

"LAG-3 is emerging as a promising target for cancer immunotherapy. We look forward to verifying ABL501's potential as a best-in-class bispecific antibody that overcomes the limitations of current LAG-3 targeting antibodies," said Sang Hoon Lee, Ph.D., CEO of ABL Bio. "This is already our third IND approval this year, demonstrating our strong commitment to building a robust portfolio of bispecific antibody immunotherapies. Carrying on this momentum, we expect to submit multiple additional INDs next year."
