The company
We are an oncology company developing next-generation antibody-drug conjugates (“ADCs”) built around novel, proprietary payloads utilizing powerful biology to attack cancer. Our lead payload, PH1, targets RNA splicing by modulating the spliceosome, a complex machinery in the cell that converts pre-RNA into spliced RNA for translation into vital proteins for cell survival and growth. PH1’s disruption of normal RNA splicing has multiple modes of action on cancer cells: 1) cell killing and cytotoxicity that causes cancer cell death and 2) generates neoantigen proteins that activates both the innate and adaptive immune systems to drive robust and durable cancer killing activity in preclinical models. Additionally, AKTX-101 is active against urothelial cancers with FGFR3- fusions, lung cancers with SMARCA4 deletions and BRAF G466V mutations, and K-Ras G12V driven pancreatic cancers, whereas the PH1 payload has been demonstrated to be active against metastatic prostate cancer cells driven by AR-v7 and AR-hormone dependent prostate cancer showing the power of the PH1 payload against oncogenes derived from spliced isoforms/variants. Utilizing the novel PH1 payload as a platform, the Company has the ability to generate a pipeline of ADC candidates each focused on a different cancer antigen target of interest (i.e. Trop-2, CEACAM5). Akari’s lead candidate, AKTX-101, targets the Trop-2 receptor on cancer cells and is engineered with a proprietary linker to deliver its novel PH1 payload directly into the tumor with minimal off-target effects.
