Study type
Interventional
Description of intervention(s) / exposure
Oglufanide disodium is to be administered for 5 of 7 days for two successive weeks, followed by two weeks without therapy. This 4 week cycle will be repeated 3 times. The first 7 cohorts will receive dose levels of 0.5ug, 5ug, 50ug, 500ug, 5mg, 15mg and 50mg subcutaneously with the 8th cohort receiving 5mg inhaled. Escalation to the next dose will only commence if no adverse event that is severe and/or serious and considered probably or definately related to the study product has been observed by the time all subjects in the previous dose level group have completed their second two week cycle of therapy.
