Study summary

Allogenic plasma aliquots, used as eye drops, will provide a source of plasminogen in the treatment of ligneous conjunctivitis. The investigational product will be available through written request from the Sponsor-Investigator to Canadian Blood Services, as approved by Health Canada.

Read the detailed description

Ligneous conjunctivitis is a chronic progressive disorder of the conjunctival mucosa which occurs secondary to plasminogen deficiency. The condition is characterized by thick, fibrous pseudo membranes adherent to the conjunctival surface of the eye lid.The investigational product, allogenic plasma aliquots, is a source of plasminogen. It will be used as eye drops, to treat recurrences of these pseudo membranes by providing the plasminogen required for fibrinolysis. The allogenic plasma aliquots are prepared by Canadian Blood Services. An initial supply of 680 vials was made available through the Special Access program, upon approval by Health Canada. Through this Clinical Trial, additional allogenic plasma aliquots will be available when required to treat recurrences of the pseudo membranes. The study has been conditionally approved by local HREB, pending registration with clinicaltrials.gov
