RV521 is an orally bioavailable inhibitor of respiratory syncytial virus (RSV) fusion that was identified after a lead optimization process based upon hits that originated from a physical property directed hit profiling exercise at Reviral. This exercise encompassed collaborations with a number of contract organizations with collaborative medicinal chemistry and virology during the optimization phase in addition to those utilized as the compound proceeded through preclinical and clinical evaluation. RV521 exhibited a mean IC50 of 1.2 nM against a panel of RSV A and B laboratory strains and clinical isolates with antiviral efficacy in the Balb/C mouse model of RSV infection. Oral bioavailability in preclinical species ranged from 42 to >100% with evidence of highly efficient penetration into lung tissue. In healthy adult human volunteers experimentally infected with RSV, a potent antiviral effect was observed with a significant reduction in viral load and symptoms compared to placebo.

Calcitonin gene-related peptide (CGRP) receptor antagonist treatment of migraine

Migraine is ranked as the sixth cause of years lost due to disability, with around 1.04 billion migraine sufferers globally. Triptans are considered the standard for acute migraine treatment, but an important number of migraineurs do not respond to them and these drugs are contraindicated in patients with cardiovascular disease. Migraine therapy is currently undergoing tremendous development, i.e., 5-HT1F receptor agonists (ditans), anti-calcitonin gene-related peptide (CGRP) monoclonal antibodies, and small-molecule CGRP receptor antagonists (gepants). Ubrogepant (MK-1620) is a small-molecule, potent and selective CGRP receptor antagonist. In two phase III clinical trials (ACHIEVE I and II), ubrogepant showed, at 2 hours, significant percentages of pain freedom, and absence of the most bothersome symptoms in migraine patients. In a phase III study to assess the long-term (52-week) safety and tolerability, ubrogepant displayed good tolerability, and no signs of hepatic toxicity. In March 2019, the U.S. Food and Drug Administration accepted the new drug application (NDA) for ubrogepant for the acute treatment of migraine.
