简要总结
The primary purpose of this study was to evaluate the safety and exploratory efficacy of SF0166 Topical Ophthalmic Solution in patients with Diabetic Macular Edema (DME).
详细描述
This was a prospective, randomized, double-masked, multicenter, Phase I/II clinical study in which 44 eligible subjects with active Diabetic Macular Edema (DME) were randomized to 1 of 2 treatment arms in a 1:1 ratio as follows: SF0166 low dose twice daily (BID) or SF0166 high dose BID.
Study subjects administered the randomly assigned treatment for 28 days. There was an additional 28-day post-treatment follow-up period. Study subjects returned for examination every 2 weeks for 8 weeks (2 months).

- •Best-corrected Visual Acuity (BCVA) between 78 and 25 letters, inclusive, in the study eye at the screening/randomization visit using Early Treatment Diabetic Retinopathy Study (ETDRS) testing, with BCVA decrement primarily attributable to Diabetic Macular Edema (DME).

- •Macugen (pegaptanib): 45-day washout
- •Willing and able to return for all study visits.
- •Able to adhere to the study dosing requirements.
- •Understands and signs the written informed consent form.
排除标准
- •Active proliferative diabetic retinopathy (PDR) in the study eye, such as neovascularization of the optic disc (NVD), neovascularization elsewhere (NVE), vitreous hemorrhage, or neovascular glaucoma.
- •Uncontrolled glaucoma or ocular hypertension in the study eye defined as an intraocular pressure (IOP) >25 millimeter of mercury (mmHg) regardless of concomitant treatment with IOP-lowering medications.
- •Uncontrolled hypertension defined as systolic >180 mmHg or >160 mmHg on 2 consecutive measurements (during the same visit) or diastolic >100 mmHg on optimal medical regimen.
- •Screening glycated hemoglobin (HbA1c) blood test >12.0%.
- •Previous panretinal photocoagulation (PRP) in the study eye within 4 months of study enrollment, or the need for PRP during the study based on the Investigator's opinion.

- •Intravitreal/periocular/topical ocular steroids of any type in the study eye within 90 days (3 months) prior to study enrollment.
- •Placement of Iluvien or Retisert (fluocinolone acetonide intravitreal implant) in the study eye within 36 months (3 years) prior to study enrollment.
- •Use of Ozurdex (dexamethasone intravitreal implant) in the study eye within 180 days (6 months) prior to study enrollment.
- •Significant epiretinal membrane, posterior hyaloidal traction, and/or vitreomacular traction in the study eye as determined by the optical coherence tomography (OCT) results.
- •Previous pars plana vitrectomy in the study eye.
- •Any intraocular surgery in the study eye within 90 days (3 months) prior to study enrollment.
- •Yttrium aluminium garnet (YAG) laser treatment in the study eye within 30 days (1 month) prior to study enrollment.
- •Concomitant use of any topical ophthalmic medications in the study eye, including dry eye or glaucoma medications, unless on a stable dose for at least 90 days (3 months) prior to study enrollment and expected to stay on stable dose throughout study participation. Artificial tears are allowed.
- •High myopia in the study eye, with a spherical equivalent of >8.00 Diopters (D) at screening.
- •Chronic or recurrent uveitis in the study eye.
- •Ongoing ocular infection or inflammation in either eye.
- •A history of cataract surgery complicated by vitreous loss in the study eye.
- •Congenital eye malformations in the study eye.
- •A history of penetrating ocular trauma in the study eye.
- •Mentally handicapped.
- •Females of childbearing potential (i.e., who are not postmenopausal for at least 1 year or surgically sterile for at least 6 weeks prior to Visit 1 - Screening/Randomization) who are lactating, or who are pregnant as determined by a positive urine pregnancy test (UPT) at Visit 1 - Screening/Randomization. Women of childbearing potential must agree to use acceptable methods of birth control throughout the study. Acceptable methods of birth control include tubal ligation, transdermal patch, intrauterine devices/systems, oral/implantable/injectable or contraceptives, sexual abstinence, double barrier method, or vasectomized partner.
- •Participation in any other investigational device or drug clinical research study within 30 days of Visit 1 - Screening/Randomization.
- •Contraindication to the study medications or fluorescein dye.
- •Other ocular pathologies that in the Investigator's opinion would interfere with the subject's vision in the study eye.
