Oncology biotech Akari Therapeutics has announced a partnership with WuXi XDC, an antibody-drug conjugate (ADC) development and manufacturing company, to accelerate Akari’s drug development and manufacturing.
Boston-based Akari is focused on ADCs with novel RNA splicing–modulating payloads, and its lead program, AKTX-101, targets metastatic urothelial cancer, according to an April 6 release.
In the release, Akari Therapeutics President and CEO Abizer Gaslightwala called the partnership a “major milestone” for the company and a validation of its technology.
Akari says its asset could expand second-line treatment options for urothelial cancer beyond standard chemotherapy. The company’s proprietary PH1 is a spliceosome inhibitor payload that works by disrupting RNA splicing within cancer cells, leading to cell death. AKTX-101 is expected to enter a phase 1 trial late this year or in early 2027.
WuXi XDC is a contract organization that specializes in bioconjugates, offering preclinical-to-commercial manufacturing services covering antibodies and other biologics intermediates, chemical payloads and linkers, and bioconjugate drug substances and products.
