Dry Eye Clinical Trial - Topical Fibrinogen-Depleted Human Platelet Lysate

Status Completed

Clinical Trial Summary

The purpose of this Phase 1/2 study is to compare the safety and tolerability of four times a day (QID) dosing of a non-preserved topical ocular drop formulation of 10 vol/vol % and 30 vol/vol % of FD hPL to vehicle control eye drops in patients with Dry Eye Disease (DED) secondary to Graft vs. Host Disease (GvHD).

Clinical Trial Description

For patients who do not find relief from other modes of therapy, autologous serum tears have been used as an alternative therapy since the mid-1980s. Limitations such as the need for periodic blood draws, the lack of standardization in the preparation of AST and platelet-enriched plasma tears, the unknown shelf life of AST preparations, the use of non-preserved multi-dose packaging and the practical difficulties patients face in storing these products frozen or refrigerated have hindered their widespread use for treating GvHD and other forms of severe tear deficiency. To address these shortcomings, Cambium Medical Technologies, LLC has developed a proprietary method of standardizing and manufacturing a fibrinogen-depleted standardized platelet lysate using pooled human platelet lysates (phPL) collected from qualified healthy donors (CAM-101). Because Cambium's proprietary manufacturing process depletes pooled human platelet lysates of fibrinogen (the key clotting protein in platelets), the remaining product contains enriched levels of several key nutritive and regenerative components than are normally found in non-standardized AST as well as healthy tear film. Given the multi-factorial nature of DED, the enriched levels of numerous key nutritive components in CAM-101 may well prove to be superior to artificial tears and certain single active ingredient products which treat only one cause or contributor of dry eye (e.g., inflammation) and other forms of tear deficiency. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
