Study to Investigate the Safety, Tolerability, Biological Effects and Preliminary Pharmacokinetics of Increasing Doses of BIIL 284 BS in Healthy Male Volunteers

Study Overview
=================
Brief Summary
-----------------
The objective of the present study is to obtain information about the safety and tolerability of BIIL 284 BS after repeated dosing, to find the pharmacologically active dose range by determination of the surrogate marker CD 11b (= Mac-1) and to obtain preliminary pharmacokinetic data concerning steady state and accumulation factor

Official Title
-----------------
A Double-blind, Randomised, Placebo-controlled, Parallel-group Study to Investigate the Safety, Tolerability, Biological Effects and Preliminary Pharmacokinetics of Increasing Repeated Oral Doses (9 Days Dosing) of BIIL 284 BS (Doses: 25 mg, 150 mg, 250 mg as WIF Tablets) in Healthy Male Volunteers

Conditions
