Iksuda Therapeutics is a biotechnology company focused on developing antibody drug conjugates (ADCs) for treating difficult-to-treat cancers. The company's ADC pipeline leverages a portfolio of tumor-activated prodrug payloads combined with stable conjugation technologies like its proprietary PermaLink platform. Iksuda's ADCs aim to enhance the therapeutic index, improving safety and efficacy for cancer patients.
One of Iksuda's lead candidates is IKS014, a potential best-in-class HER2-targeting ADC that demonstrated impressive activity against high and low HER2-expressing tumors in preclinical trials, with significantly higher non-severely toxic doses compared to other HER2-directed drugs. In October 2023, the first patient was dosed in a Phase 1 trial of IKS014 for advanced HER2+ solid tumors, following positive Phase 1 data from Fosun Pharma's trials of the same ADC (designated FS-1502) in China.
Another promising ADC is IKS03, a best-in-class CD19-targeting therapy delivering a tumor-activated prodrug pyrrolobenzodiazepine payload. preclinical studies showed superior efficacy versus marketed CD19 therapies and higher maximum tolerated doses, highlighting its potential as a leading treatment for B-cell cancers. Phase 1 trials for IKS03 were expected to begin in 2022, with initial patient data anticipated in Q3 2022.
In January 2022, Iksuda expanded its pipeline through a licensing deal with LegoChem Biosciences, gaining exclusive worldwide rights (excluding Greater China and South Korea) to LCB14, now designated IKS014.
