Pilot Study for the Evaluation of Finasteride in the Treatment of Chronic Central Serous Chorioretinopathy
United States5 participantsStarted 2009-02
Plain-language summary
Central serous chorioretinopathy (CSC) is a retinal disorder characterized by an accumulation of serous fluid under the retina. Although acute CSC tends to spontaneously resolve on its own with minimal sequelae, chronic CSC tends to persist and lead to irreversible visual loss. The pathogenesis of CSC is complex; however, systemic androgens have been implicated. Finasteride is an anti-androgen medication that is widely used in the treatment of various conditions. The objective of this study was to investigate the safety and potential efficacy of oral finasteride as a treatment for chronic CSC.
Five participants with chronic CSC were enrolled into this uncontrolled, unmasked, Phase I/II study. An oral dose of finasteride, 5 mg daily, was administered to all participants for three months.
Following this, finasteride was withheld and participants were observed for another three months. If a participant experienced a beneficial effect during the period in which he received finasteride and then experienced a relapse during the observation period, finasteride was re-instituted for the remaining period of the study. Relapse was defined as a return to the baseline maximum lesion height and/or return to baseline lesion volume.

Inclusion criteria
✓. Participant must be 18 years of age or older.
✓. Participant must understand and sign the protocol's informed consent document.
✓. Female participants of childbearing potential must not be pregnant or breast-feeding, must have a negative pregnancy test at screening and must be willing to undergo monthly pregnancy tests throughout the study.
✓. Female participants of childbearing potential must agree to practice two\* acceptable methods of birth control throughout the course of the study and for three months after their last oral dose of finasteride. Acceptable methods of birth control include hormonal contraception (birth control pills, injected hormones or vaginal ring), intrauterine device, barrier methods with spermicide (diaphragm with spermicide, condom and spermicide) or surgical sterilization (hysterectomy, tubal ligation or vasectomy in a partner).
✓. Participant agrees to take the appropriate precautions to ensure that persons who are pregnant, nursing or of childbearing potential do not handle the finasteride tablets.
Exclusion criteria
✕. Participant is in another investigational study and actively receiving study therapy.
What they're measuring

Change in Visual Acuity at Month 3 Compared to Baseline.
. Participant is unable to comply with study procedures or follow-up visits.
✕. Participant has evidence of ocular disease other than CSC in either eye that may confound the outcome of the study (e.g., diabetic retinopathy with 10 or more hemorrhages or microaneurysms, uveitis, pseudovitelliform macular degeneration, moderate/severe myopia, etc.).
✕. Participant has evidence of CNV.
✕. Participant has abnormal liver function testing as defined by elevated alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels that are greater than twice the respective upper limits of normal (ULN), i.e., ALT \> 82 U/L and/or AST \> 68 U/L. If a participant has ALT or AST levels greater than twice the ULN, the participant can be enrolled if cleared by hepatology.
✕. Participant is expected to need ocular surgery during the course of the trial.
✕. Participant is on steroid medication (oral, topical or inhaled).
✕. Participant is on ocular or systemic medications known to be toxic to the lens, retina or optic nerve.
