RO0270608, the active metabolite of R411, is a dual alpha4beta1-alpha4beta7 (α4β1/α4β7) integrin antagonist. Antiinflammatory activity[1][2].
RO0270608 inhibits α4/β7 mediated cell adhesion with an IC50 of 33 nM. In a human T-cell VCAM/anti CD3 costimulation assay RO0270608 causes a pronounced inhibition of T-cell proliferation (IC50=30 nM)[2].
In a murine OVA-model of airway inflammation, RO0270608 i.n. abolishes allergen-induced inflammatory cell accumulation[2]

Pharmacokinetics, safety, and tolerability of R411, a dual alpha4beta1-alpha4beta7 integrin antagonist after oral administration at single and multiple once-daily ascending doses in healthy volunteers
J Clin Pharmacol 2004 Dec;44(12):1368-78.PMID:15545307DOI:10.1177/0091270004270147
R411 is a dual alpha4beta1-alpha4beta7 integrin antagonist under development for the treatment of chronic asthma. The objective of this study was to investigate the pharmacokinetics and safety of R411 and its active metabolite, RO0270608, in humans. A 3-part phase I trial was conducted in 132 healthy volunteers: (1) 12 subjects received 200 mg R411 as a single oral dose or 100 mg RO0270608 as an intravenous infusion in a 1-sequence crossover design; (2) 7 groups of 10 subjects received 1 of 7 single oral doses of R411 (10-1200 mg) in a parallel, placebo-controlled, ascending adaptive dose design; and (3) 5 groups of 10 subjects each received repeated oral qd doses of R411 (50-900 mg) for up to 3 weeks in a parallel, placebo-controlled, ascending adaptive dose design. The absolute bioavailability of RO0270608 (mean +/- standard deviation) after oral administration of R411 was 27% +/- 4%, and the terminal half-life was 7.33 +/- 2.29 hours. After IV infusion of RO0270608, total clearance (mean +/- standard deviation) was 19.4 +/- 7.1 L/h, and the volume of distribution was 93.1 +/- 36.1 L. After single ascending oral doses of R411, area under the concentration-time curve from 0 to infinity of active metabolite RO0270608 increased proportionally from 150 to 1200 mg (P > .05). Following repeated administration, the oral clearance was independent of time. No drug accumulation was observed, and no safety concerns were revealed up to a dose of 900 mg after up to 3 weeks of treatment.
