  Purpose

This 8 arm study will evaluate the safety, tolerability, pharmacokinetics and ph armacodynamics of single ascending doses of R1671 or placebo in patients with mi ld, intermittent, asymptomatic asthma. Patients will be randomized to receive pl acebo or R1671, at a starting dose of 0.0015mg, by intravenous infusion; this do se will be escalated in subsequent groups of patients after a satisfactory asses sment of the data from the previous dose. The anticipated time on study treatmen t is <3 months, and the target sample size is <100 individuals.
