NST-628

Nested Therapeutics’ lead program, NST-628, is an oral, brain-penetrant pan-RAF-MEK non-degrading molecular glue that lacks paradoxical pathway activation through the prevention of RAF paralog heterodimerization. By inhibiting the phosphorylation and activation of MEK by RAF, NST-628 targets a critical step in the RAS/RAF/MAPK signaling pathway. Preclinically, NST-628 results in broad efficacy, high tolerability, CNS activity across various RAS- and RAF-driven tumor models, and has the potential to deliver transformative clinical benefits both as a monotherapy and as a key component in combination therapies. Now, NST-628 has advanced to a Ph. I trial in patients with refractory MAPK pathway mutated/dependent advanced solid tumors.
