Brief Title  ICMJE AP-05-002 A Safety and Efficacy Study of Oral Danazol (a Previously Approved Drug)in the Treatment of Diabetic Macular Edema
Official Title  ICMJE A Randomized, Placebo-Controlled, Parallel, Double-Masked Study to Evaluate the Efficacy and Safety of Two Doses of Oral Optina in Adult Patients With Diabetic Macular Edema
Brief Summary

This study will evaluate the efficacy of ultra low dose danazol (Optina) for the treatment of diabetic macular edema versus placebo. Optina has already been granted 505(b)2 status by the FDA and will incorporate all safety data from prior FDA approvals. Additional safety data will be collected specifically for this low dosage.

This study will identify a population of subjects where Optina demonstrates a therapeutic effect.

A portion of 505(b)2 drugs are approved based on a single clinical trial.

Detailed Description This study will identify a population of subjects where Optina demonstrates a therapeutic effect.

Eligibility Criteria  ICMJE

Study Level Inclusion Criteria:

  1. Subject is willing and able to provide informed consent for study participation
  2. Male or female 18 years or older with Type 1 or 2 diabetes mellitus [defined as a self-report of diabetes accompanied by treatment (insulin or diet) or a history of fasting plasma glucose ≥ 7.0 mmo/l (126 mg/dl) or 2-hr plasma glucose ≥ 11.1 mmo/l (200 mg/dl)]
  3. Female subjects of childbearing potential must have a negative pregnancy test within 7 days prior to randomization and must agree to utilize a reliable form of effective contraception (hormonal or barrier method; abstinence) throughout the study and for 90 days after the last dose of study medication. Childbearing potential is defined as women who have had menses within the past 12 months, who have not had tubal ligation or bilateral oophorectomy [Note: patients using contraceptive methods containing progesterone (including a progesterone IUD) for 90 days prior to randomization or planning to use progesterone contraceptive methods (including a progesterone IUD) during the study drug treatment period are not eligible for enrollment.] Should a woman become pregnant or suspect that she is pregnant while participating in this study, she should inform her treating physician immediately
  4. Enrollment in this study is contraindicated for pregnant or lactating women. Thus, female patients who are postmenopausal without a menstrual period for ≥ 12 months, surgical sterility, not pregnant and not breast feeding for 90 days prior to randomization can be enrolled
  5. At least one eye meets the study eye criteria for inclusion in the study (see Study Eye Inclusion Criteria, below)
  6. Stable diabetic and metabolic control (no major changes in diabetic or lipid reducing medications for 3 months prior to start of this study as determined by the Investigator)

Study Eye Inclusion Criteria (if both eyes meet criteria, both eyes will be study eyes)

  1. Change in VA within previous 12 months reasonably believed to be associated with DME in the opinion of the Investigator
  2. BCVA in accordance with ETDRS letter score of ≥24 (e.g., 20/320 or better) and ≤78 (e.g., 20/32 or worse)
  3. Definite retinal thickening ≥275 microns on spectral-domain OCT due to DME involving the center of the macula on clinical exam in the opinion of the Investigator
  4. Media clarity, pupillary dilation, and patient cooperation sufficient for adequate fundus photographs
  5. Assessment by the Investigator that focal photocoagulation can be deferred safely for 16 weeks

Study Level Exclusion Criteria:

  1. Known allergy to any danazol (Cyclomen® or Danocrine®) or any other non-medicinal component of the danazol test drug (cornstarch, lactose, magnesium stearate, gelatin, and talc) (Note: Lactose intolerance is not a contraindication to ingesting the small amount of lactose contained in oral medications)
  2. Known allergy to any component of the placebo test drug (lactose, magnesium stearate, and gelatin)
  3. History of systemic (e.g., oral, intravenous, intramuscular, subcutaneous, intra-uterine, epidural, bursal, or implanted) androgens, progesterone or corticosteroids (including topical ophthalmic corticosteroids preparations within 4 months prior to randomization (topical non-ophthalmic corticosteroids are not excluded)
  4. Blood pressure >180/110 mm Hg (in cases where either or both of the systolic or diastolic limits are exceeded, blood pressure can be re-measured after 10 minutes rest period for inclusion in the study)
  5. HbA1c greater than 11% or consistent HbA1c values in a similar range for the last 6 months.
  6. Carcinoma of the breast
  7. Prostate cancer
  8. Androgen-dependent tumor
  9. Undiagnosed abnormal genital bleeding
  10. Genital neoplasia
  11. Currently taking warfarin (coumadin), carbamazepine, phenytoin, phenobarbital cyclosporin or tacrolimus
  12. Females who are pregnant or planning pregnancy in the 6-month period after randomization (Note: Enrollment in this study is contraindicated for pregnant or lactating women)
  13. Females breast feeding or breast feeding in the 90 days prior to randomization (Note: Enrollment in this study is contraindicated for pregnant or lactating women)
  14. Use of any hormonal therapies including hormone replacement therapy (HRT) and contraceptive medications that contain progesterone within 3 months before randomization (Note: patients on pure estrogen or estradiol replacement therapy can be enrolled in the study)
  15. Unstable cardiovascular disease or a history of significant heart disease (including unstable angina, acute coronary syndrome, myocardial infarction, or history of coronary revascularization procedure) within 6 months before randomization
  16. Any condition that, in the opinion of the Investigator, would preclude participation in the study (e.g., unstable medical status including blood pressure and glycemic control). Patients in poor glycemic control who, within the last 3 months, using a new type of insulin (for example, changing to or adding a short acting insulin from a longer-acting insulin), or increased the daily dose ≥ 50%, initiated intensive insulin treatment such as an insulin pump or additional daily injections or plan to do so in the next 3 months should not be enrolled.
  17. Significant hepatic disease (defined as aspartate aminotransferase, alanine aminotransferase or alkaline phosphatase [ALP], more than twice the upper limit of normal) where, in the opinion of the Investigator, danazol might be contraindicated
  18. Significant renal disease (defined as serum creatinine ≥ 2.5 mg/dl, history of renal transplant, or undergoing dialysis at screening) where, in the opinion of the Investigator, danazol might be contraindicated
  19. Changes in anti-hypertensive medication within 3 months before randomization (except for dosage adjustments that are considered minor in the opinion of the Investigator)

  23. Patient is expecting to move out of the area of the clinical center during the next 6 months

Study Eye Exclusion Criteria:

  1. Macular edema considered to be due to a cause other than DME; e.g., cataract extraction, vitreo-retinal interface disease (a taut posterior hyaloid or epiretinal membrane)
  2. An ocular condition is present such that, in the opinion of the Investigator, VA would not improve from resolution of macular edema (e.g., foveal atrophy, closure of juxafoveal capillaries, dense subfoveal hard exudates)
  3. An ocular condition (other than diabetic retinopathy) that, in the opinion of the Investigator, might affect macular edema or alter VA during the course of the study, e.g., vein occlusion, uveitis or other ocular inflammatory disease, Irvine-Gass Syndrome, etc.
  4. Substantial cataract that, in the opinion of the Investigator, is likely to interfere with ocular measurements or evaluations during this study
  5. History of treatment for DME at any time in the past 8 weeks (such as focal/grid macular photocoagulation, intravitreal or peribulbar corticosteroids, anti-vascular endothelial growth factor [VEGF drugs], or any other treatment). Note, the 28-day screening period allows subjects to be screened at 4 weeks post DME treatment and have a baseline visit 28 days later.
  6. History of panretinal scatter photocoagulation (PRP) within 4 months prior to randomization or anticipated need for PRP in the 6 months following randomization
  7. History of major ocular surgery (including cataract extraction, scleral buckle, any intraocular surgery, etc.) within prior 6 months or anticipated within the next 6 months following randomization
  8. History of YAG capsulotomy performed within 2 months prior to randomization
