GT Biopharma Announces Preclinical Results For Its ROR1 TriKE™ As A Treatment For Prostate Cancer
BEVERLY HILLS, Calif., March 8, 2021 /PRNewswire/ -- GT Biopharma, Inc. (NASDAQ: GTBP), a clinical stage biopharmaceutical company focused on disruptive, target-directed Natural Killer (NK) cell engager immunotherapy technologies (TriKE™) for cancer, announces preclinical results for its ROR1 TriKE™ product candidate as a prospective therapy for the treatment of prostate cancer.
Tyrosine kinase transmembrane receptor ROR1 has recently been shown to be overexpressed on certain cancer cells, and appears to play a functional role in promoting migration/invasion and influencing the metastatic potential of various solid tumor cancers. Targeting ROR1 on cancer cells with TriKE™ and redirecting NK cells to attack and kill cancer cells expressing ROR1, could result in a therapeutic treatment that limits the metastatic potential and invasiveness of certain solid tumor cancers.
The ROR1 TriKE™ was evaluated in several preclinical models of prostate cancer, and was found to be effective at promoting NK cell killing of multiple prostate cancer cells including LnCAP, C4-2, PC-3, DU-145, VCaP and 22RV1. Significant NK cell activation and interferon gamma (IFNγ) production was also observed as a result of TriKE™ engagement and activation of the NK cell.
"We are pleased to report our ROR1 TriKE™ has passed this important preclinical milestone, and demonstrated effectiveness in promoting redirected and target-specific killing by NK cells," said Anthony J. Cataldo, GT Biopharma's Chairman and Chief Executive Officer. "We plan to evaluate the ROR1 TriKE™ in additional IND-enabling preclinical studies with the goal of transitioning to a Phase I/II clinical trial."
