Immutep (IMMP) announces the successful scale-up of the manufacturing of its lead product candidate eftilagimod alpha, a first-in-class soluble LAG-3 protein, with the completion of a 2,000L manufacturing run. In preparation for late-stage clinical trials and commercial production, Immutep has been working with WuXi Biologics (WXXWY) to increase the efti manufacturing process from 200L to 2,000L capacity single-use bioreactors at the manufacturing plant in Wuxi city, China. The first 2,000L manufacturing run has been performed successfully with all predefined release criteria met.
