First-in-Human Study for a Selective Rearranged During Transfection Tyrosine Kinase Inhibitor, GSK3352589, to Investigate the Safety, Tolerability, and Pharmacokinetics in Healthy Volunteers.

Rearranged during transfection (RET), a neuronal growth factor receptor tyrosine kinase, regulates the development of sympathetic, parasympathetic, motor, and sensory neurons in the enteric nervous system. The intended site of action for GSK3352589 is intestinal tissues. GSK3352589 is an RET kinase inhibitor that was administered in double-blind, randomized, placebo-controlled single-dose (SD) and repeat-dose (RD) studies in healthy subjects to investigate its safety/tolerability and pharmacokinetics.

First-in-Human Studies for a Selective RET Tyrosine Kinase Inhibitor, GSK3179106, to Investigate the Safety, Tolerability, and Pharmacokinetics in Healthy Volunteers.

Rearranged during transfection (RET), a neuronal growth factor receptor tyrosine kinase, regulates the development of the sympathetic, parasympathetic, motor, and sensory neurons in the enteric nervous system. GSK3179106 is a RET kinase inhibitor that was administered in double-blind, randomized, placebo-controlled single-dose and repeat-dose studies in healthy subjects to investigate its pharmacokinetics and safety/tolerability. In the single-dose study (n = 16), GSK3179106 was dosed from 10 mg to 800 mg, including a food effect arm.

Randomized clinical study of safety, pharmacokinetics, and pharmacodynamics of RIPK1 inhibitor GSK2982772 in healthy volunteers.

GSK2982772 is a highly selective inhibitor of receptor-interacting protein kinase 1 (RIPK1) being developed to treat chronic inflammatory diseases. This first-in-human study evaluated safety, tolerability, pharmacokinetics (PK), and exploratory pharmacodynamics (PD) of GSK2982772 administered orally to healthy male volunteers. This was a Phase I, randomized, placebo-controlled, double-blind study.
