A Clinical Study to Evaluate the Potential Role of ACTH Gel in Patients With Scleritis (ATLAS)

This is an interventional treatment trial for Scleritis focused on measuring Scleritis, anterior, adrenocorticotropic hormone, ACTH, Non-infectious Read More

Inclusion Criteria:

• Adults, age ≥ 18 years;
• Able to give informed consent and attend all study visits;
• Have diagnosis of non-necrotizing scleritis determined by the Investigator to be non-infectious;
• Have active scleirits, defined as:
• Characteristic clinical presentation of active disease: painful inflammation, edema and tenderness to touch radiating to the forehead, the brow, the jaw, or the sinuses. Severity of pain associated with scleritis will be based on pain intensity, NRS scale.
• Scleral inflammation ranging from +1 to +3 as assessed by central reading center based on standardized scleritis grading scale.

and:

• are receiving no other treatment; or,
• are receiving prednisone (or equivalent dose of another corticosteroid) and/or at least 1 other systemic immunosuppressant;
• Have anterior scleritis.
• Sufficient inflammation to require systemic treatment or long-term regional treatment.
• Subjects whom the investigators feel may only need short-term topical therapy should not be enrolled.
• Best-corrected visual acuity (ETDRS method) of 20/20 to 20/400 in the study eye;
• Best- corrected visual acuity (ETDRS method) of 20/400 or better in the fellow eye
• Must have a chest radiograph within 3 months prior to enrollment with no evidence of malignancy, infection or fibrosis.
• Females of childbearing potential must have a negative urine pregnancy test at screening. In addition, sexually active females of childbearing potential must agree to use TWO of the following adequate forms of contraception while on study medication: oral, injectable, or implantable hormonal contraceptives; tubal ligation; intrauterine device; barrier contraceptive with spermicide; or vasectomized partner.
• Males must agree to use barrier contraception (latex condoms) when engaging in sexual activity while on study medication and for 28 days after taking the last dose of study medication.
• Prior to study screening, potential subjects must have been evaluated and screened for infectious etiologies by the investigators, possibly as part of standard clinical acre; all testing to rule out infectious causes must be performed within 3 months of screening for the ATLAS study.
• Currently active and uncontrolled scleritis, that at the determination of the investigator, requires the initiation of corticosteroid monotherapy (or equivalent), or prednisone therapy and immunomodulatory therapy or injections of corticosteroid (periocular); or scleritis in subjects for whom oral corticosteroid is contraindicated, relatively or absolutely.
• Evidence of active non-infectious scleral inflammation that at the determination of investigator requires therapy. Such evidence can be documented by clinical examination, photography, or ancillary testing (e.g. B-scan ultrasonography, fluorescein angiography, optical coherence tomography). As long as the investigator determines that the degree of inflammation can be monitored for regression or progression, the inflammation criterion can be met.
• Not planning to undergo elective ocular surgery during the first 6 months of the study.
• Subjects who have developed scleritis as ocular manifestation of an underlying systemic disease can be enrolled in the study only if the systemic therapy will not be altered throughout the study span. If at any point during the study, the ongoing systemic therapy needs to be altered (e.g. increase in the dose), the subject will have to exit the study.
• If scleritis is the initial manifestation of an underlying systemic disease, and the subjects need to be started on systemic therapy in the form of corticosteroids or immunomodulatory therapy for the underlying disease, then the subjects will not be eligible to participate in the study.
• Subjects with any or all of the following ocular complications associated with or secondary to scleritis may also be eligible for enrollment:
• Evidence of active anterior uveitis (defined as +1 cells or more in the anterior chamber or evidence of anterior vitreous inflammation on slit-lamp examination at presentation).
• Ocular hypertension, defined as intraocular pressure of ≥ 21 mmHg.
• Peripheral keratitis; defined as peripheral interstitial keratitis or thinning with either ulcerative or non-ulcerative component.10
• Subjects who have been on immunomodulatory therapy (IMT) prior to enrollment may participate in the study if they have been on a stable dose of IMT (at least 4 weeks with no change in IMT dosing or addition of new IMT agents).

Exclusion Criteria:

• Any significant ocular disease that could compromise vision in the study eye. These include, but are not limited to:

  • Diabetic retinopathy: proliferative diabetic retinopathy (PDR) or non-proliferative diabetic retinopathy (NPDR) that compromise the vision.
  • Age-related macular degeneration;
  • Myopic degeneration with active subfoveal choroidal neovascularization.
  • Advanced glaucoma status post trabeculectomy or tube/valve placement

• Any of the following treatments within 90 days prior to Day 0 or anticipated use of any of the following treatments to the study eye:

  • Intravitreal injections (including but not limited to steroids or anti-vascular endothelial growth factors);
  • Posterior subtenon's steroids.
• Intraocular surgery within 90 days prior to Day 0 in the study eye;
• Capsulotomy within 30 days prior to Day 0 in the study eye;
• Any known ocular surgery (including cataract extraction or capsulotomy) of the study eye anticipated within the first 180 days following Day 0;
• Presence of posterior scleritis as the only type of scleritis (without concurrent presence of any type of anterior scleritis;
• Intraocular pressure ≥25 mmHg in the study eye (glaucoma subjects maintained on no more than 2 topical medications with IOP <25 mmHg are allowed to participate);
• Pupillary dilation inadequate for quality stereoscopic fundus photography in the study eye;
