Harbour BioMed announced that it has successfully completed the dosing of first patient in phase I trial of B7H4x4-1BB bispecific antibody HBM7008 in Australia.
CAMBRIDGE, Mass. and ROTTERDAM, Netherlands and SUZHOU, China, May 25, 2022 /PRNewswire/ -- Harbour BioMed (“HBM”, HKEX: 02142) announced that it has successfully completed the dosing of first patient in phase I trial of B7H4x4-1BB bispecific antibody HBM7008 in Australia. This study will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity of HBM7008 in patients with solid tumors.
HBM7008 is generated from our unique and innovative HBICE® platform, leveraging the advantages of HBM HCAb and H2L2 platforms. It targets Tumor-Associated Antigen (B7H4), mediated crosslinking T cell activation through 4-1BB. B7H4 is overexpressed on a variety of solid malignancies, including breast, ovarian, endometrial, and non-small cell lung cancers. With its crosslinking dependent specificity on tumors and potent immune modulation activity, HBM7008 has shown excellent safety profile with strong anti-tumor efficacy in the pre-clinical study, including completed response observed in the mouse tumor model.
As the first-in-class bispecific antibody targeting B7H4 and 4-1BB, HBM7008 is expected to lead the development of next-generation immunotherapeutic. Following its global innovation and development strategy, Harbour BioMed will advance the global clinical development project of HBM7008 at full speed.
About HBM7008
HBM7008 is a bispecific antibody targeting Tumor Associated Antigen B7H4x4-1BB that not only displays high potency in the T cell co-stimulation and tumor growth inhibition, and potentially may also translate to better safety due to its strict dependency on TAA-mediated crosslinking T cell activation. HBM7008 is one of the fully human bispecific antibodies developed from the HBICE® platform of the Company. It is the only bispecific antibody against these two targets globally. Its unique specificity on tumors and immune modulation activity makes it a promising therapeutic in PD-L1 negative or PD-1/PD-L1 resistant patients. It also has the potential to avoid 4-1BB liver toxicity risk observed in other products with the benefit of its innovative biology mechanisms and bispecific design.
