PharmAbcine has signed a collaborative agreement with Merck (MSD) to evaluate its anti-VEGFR2 mAb, TTAC-0001, in combination with MSD’s anti-PD-1 (programmed death receptor-1) therapy, Keytruda (pembrolizumab), in patients with recurrent glioblastoma multiforme (rGBM) and metastatic triple-negative breast cancer (TNBC).
PharmAbcine’s lead candidate TTAC-0001, an investigational therapy, is a highly selective and potent anti-VEGFR2 (KDR/flk-1) mAb in clinical development for rGBM indications.
VEGFR2 is over-expressed in most malignant tumors, such as gastric, liver, non-small cell lung cancer (NSCLC), ovarian, brain, colorectal, and breast cancers and this signaling pathway is a key regulator for tumor angiogenesis.
Increased understanding of the role of VEGF/VEGFR2 in the tumor microenvironment (TME) supports the rationale for evaluating TTAC-0001 in combination with KEYTRUDA.
PharmAbcine president and CEO Dr Jin-San Yoo said: “The combination of the anti-VEGFR2, TTAC-0001 and the anti-PD-1 therapy, KEYTRUDA in this study has the potential to build upon the responses already observed with each of these molecules as monotherapies.
“There is a strong biologic rationale to combine these therapies as their complementary mechanisms of action may enhance the anti-tumor activity.”
Under the terms of the collaboration, PharmAbcine will conduct international Phase I/II studies to evaluate the potential clinical synergy of combining TTAC-0001 with KEYTRUDA.
