Brief summary
APL-2 is an experimental drug being developed by Apellis Pharmaceuticals Inc for the potential use as a treatment for people with a broad range of blood disorders (including paroxysmal nocturnal hemoglobinuria (PNH)) and certain types of auto-immune diseases). PNH is caused by a small change to the individual’s genes, which results in red blood cells being broken down prematurely. People with PNH typically feel tired and often see some blood in their urine. The condition is unfortunately progressive with sufferers needing increasing medical care, with an average life expectancy of only 10 years after diagnosis. The currently available treatments are insufficient to deal with this complex disease with most patients not fully responding to the treatments. APL-2 works in a different way to the drugs that are currently approved, and has been shown in laboratory studies to prevent the breakdown of red blood cells and keep them healthy. It is hoped that APL-2 will help improve the quality of life and reduce the severity of the condition for PNH sufferers. This study will be first study of APL-2 in humans. The assessments of the safety, tolerability, pharmacokinetics, and pharmacodynamics following administration of single doses of APL-2 will guide decisions to further develop the drug.
Interventions
Subjects will be randomly assigned to treatment with either a single subcutaneous injection of APL-2 or a single subcutaneous injection of placebo. This study will be conducted in 6 sequential cohorts.
The first cohort will receive 45 mg of APL-2 (4 subjects) or placebo (2 subjects).
The second cohort will receive 90 mg of APL-2 (4 subjects) or placebo (1 subject).
The third cohort will receive 180 mg of APL-2 (4 subjects) or placebo (1 subject).
The fourth cohort will receive 360 mg of APL-
