Treatment Safety and Efficacy of Pro-ocular™ 1% for Chronic Ocular Graft Following Allogeneic HSCT.

Treatment Safety and Efficacy Using Pro-ocular™ 1% for Chronic Ocular Graft-versus-host Disease (GvHD) Following Allogeneic Hematopoietic Stem Cell Transplantation.

To evaluate the safety and efficacy of Pro-ocular™ 1% topical gel administered twice daily for 70 days in reducing or eliminating symptoms and signs of chronic ocular GvHD.

Ocular graft versus host disease presents a most severe form of ocular surface disease that compromises quality of life of afflicted allogeneic hematopoietic transplantation patients.

A controlled study is necessary to verify findings obtained to date in isolated patients. Currently available ophthalmic solutions and suspensions, drugs and devices largely have not been effective in alleviating the suffering of chronic ocular GvHD patients. Thus, this is an unmet need that Pro-ocular™ topical gel can fulfill.

Potential benefits: Decrease or cessation of adverse ocular symptoms and signs of chronic ocular GvHD, reduction or elimination of the need for other topical ocular therapeutic treatments for chronic ocular GvHD, and restoration of quality of life.

2. Has the diagnosis of chronic ocular GvHD.
3. Has an NIH Consensus Eye Score of at least 2.
4. On the GLIA Ocular Surface Disease Symptoms Questionnaire at Screening, has ocular discomfort at a severity score of moderate or more, and at least one other symptom at a severity of moderate or more.

4. Anticipate change of vision correction or anticipate any ocular procedures during study period.
5. A woman who is pregnant, nursing an infant, or planning a pregnancy.
