Abstract

In Asia, there is a need for agents to treat chronic angle closure glaucoma. This article highlights factors in determining whether to conduct an active or placebo control study and special circumstances that increase the complexity of this decision in clinical trials for chronic angle glaucoma trials. The authors advise the use of a placebo control design in pivotal clinical trials dealing with chronic angle closure glaucoma. Once a medication is approved for use in chronic angle closure glaucoma, subsequent pivotal trials of similar drugs can use an active control design.
