This Phase 1 study evaluated efficacy/safety of inhaled single-dose MK-5475, an investigational, small-molecule stimulator of soluble guanylate cyclase designed for inhaled delivery via a dry-powder inhaler device, in participants with pulmonary arterial hypertension.
The findings reveal that treatment with inhaled single-dose MK-5475 reduced pulmonary vascular resistance and increased pulmonary blood volume. Compared to the placebo, MK-5475 was well tolerated without causing vasodilatory systemic side effects. This study, conducted on adult participants with pulmonary arterial hypertension, showcases the promising pulmonary selectivity and favourable safety/tolerability profile of MK-5475, laying the groundwork for further clinical development.
