Linnaeus Therapeutics Inc., a privately-held clinical-stage biopharmaceutical company focused on the development and commercialization of novel small molecule oncology therapeutics, announced the expansion of its ongoing clinical collaboration with Merck to include multiple additional phase 2 cohorts. Based on promising preliminary safety, pharmacodynamic and efficacy data, this expanded agreement will allow the companies to further evaluate the combination of LNS8801 and Merck's anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) in patients with selected advanced solid tumors.
LNS8801 is a first-in-class, orally bioavailable small molecule that is a highly specific and potent agonist of the G-protein estrogen receptor (GPER). GPER is widely expressed on cancers. Stimulating GPER rapidly and durably depletes the c-Myc oncoprotein, stops cancers from proliferating, and makes them more visible to the immune system.
Linnaeus and Merck are currently evaluating the combination of LNS8801 and KEYTRUDA in patients who had previously responded to PD-1/L1 therapy but have subsequently progressed on PD-1/L1 inhibitors. Additionally, Linnaeus is currently evaluating LNS8801 as a monotherapy in patients that cannot tolerate PD-1/L1 therapy due to serious immune-related adverse events.
Under the terms of the agreement, Linnaeus will conduct six additional Phase 2 cohorts evaluating the combination of LNS8801 and KEYTRUDA in several indications including NSCLC, head and neck cancer, cutaneous and uveal melanoma, among others.
