In pre-clinical studies, ACE1702 exhibited cancer-specific cytotoxicity and superior potency against low HER2 tumors. Preliminary data in pts showed no CRS, GvHD, or DLTs through doses of 3B cells/cycle and antitumor activity in a HER2 < 3+ tumor. Dose escalation continues up to 15B cells/cycle with updated clinical data to be provided.

The irradiated and cryopreserved ACE-oNK-HER2, designated as ACE1702, retained superior HER2-specific in vitro and in vivo potency with no tumorigenic potential. In conclusion, this study provides the evidence to support the potential clinical application of ACE1702 as a novel off-the-shelf NK cell therapy against HER2-expressing solid tumors.

Conclusions Here we introduced a novel trastuzumab-modified oNK cell product with enhanced specificity against myriad types of HER2+ cancers. Selective conjugation of trastuzumab with membrane proteins contributing to NK activation conferred ACE1702 with enhanced cytotoxicity even in the suppressive tumor microenvironment.

In this work, we develop a NK cell therapy product ACE1702, a novel NK cell line oNK conjugated with Trastuzumab, and assess its potency against HER2+ solid tumors.MethodsoNK cells, a fluorescence-activated cell sorting (FACS) isolated CD16+ population sorted from NK-92 cells, was covalently conjugated with monoclonal antibody Trastuzumab after sublethal irradiation by our patented antibody-cell conjugates (ACCTM) platform to become our cryopreserved final product ACE1702 compliant with current good manufacturing practice (cGMP). Furthermore, in vivo results in human ovarian cancer cell line SK-OV-3-bearing xenograft mouse model supported the in vitro observations. Compared to other immunotherapeutic strategies such as antibody-drug conjugate, allogeneic NK and chimeric antigen receptor (CAR) modification, ACCTM platform underscores its power in compatibility with diverse antibodies, ease for mass production compliant with good manufacturing practice and affordability to patients.ConclusionHere we introduced a novel Trastuzumab-modified oNK cell product with enhanced specificity against myriad types of HER2+ cancers even in the presence of Herceptin resistance, and demonstrated the non-tumorigenic potential of non-irradiated oNK cells and ACE1702.
