Mersana to get $100M upfront fee from GSK for co-commercialization of XMT-2056 08/08 MRSN, GSK Mersana Therapeutics (MRSN) announced a global collaboration that provides GSK (GSK) an exclusive option to co-develop and commercialize XMT-2056, an Immunosynthen ADC that targets a novel epitope of HER2. XMT-2056 is designed to activate the innate immune system through STING signaling in both tumor-resident immune cells and in tumor cells."GSK brings highly complementary development and commercial capabilities, a wealth of immuno-oncology experience, a deep knowledge of the STING pathway and a shared vision for XMT-2056's broad potential," said Anna Protopapas, President and Chief Executive Officer of Mersana Therapeutics. "We believe this agreement solidifies Mersana's position as a partner of choice during this momentous period in the ADC space and serves as validation for our Immunosynthen platform, which takes ADCs beyond the cytotoxic realm by enabling a targeted stimulation of the innate immune system. Additionally, the agreement structure demonstrates our ability to generate meaningful non-dilutive capital upfront to support the development of our innovative candidates while also providing the potential for meaningful downstream economics." In preclinical models, XMT-2056 demonstrated robust anti-tumor activity as a monotherapy in both HER2-high and HER2-low expressing models, and enhanced efficacy has been shown when used in combination with multiple approved agents, including trastuzumab, pertuzumab, anti-PD-1, or trastuzumab deruxtecan. Preclinical data also suggest that XMT-2056 has the potential to enable immunological memory for prolonged anti-tumor activity. Mersana expects to initiate a Phase 1 clinical trial of XMT-2056 to investigate its potential in a range of HER2-expressing tumors such as breast, gastric and non-small-cell lung cancers. The U.S. Food and Drug Administration recently granted an orphan drug designation to XMT-2056 for the treatment of gastric cancer.Under the terms of the agreement, Mersana will receive an upfront option purchase fee of $100M. Mersana also is eligible to receive up to $1.36B in the form of an option exercise payment and development, regulatory and commercial milestone payments if GSK exercises its option.
