Intravitreal Adalimumab Versus Subcutaneous Adalimumab in Non-infectious Uveitis
- Registration Number
- NCT02706704
- Lead Sponsor
- American University of Beirut Medical Center
- Brief Summary
The objective of this study is to compare and evaluate the efficacy of subcutaneous (40mg) adalimumab biweekly injections to intravitreal adalimumab (1.5 mg/ 0.03 mL) administration, given at zero, 2 weeks then every four weeks, in subjects with active non-infectious intermediate-, posterior-, or pan-uveitis.
- Detailed Description
Subject groups:
32 subjects will be enrolled in this study, 16 in each arm. They will be randomized to receive either 1.5 mg/ 0.03 mL of adalimumab by intravitreal injection or 40 mg of adalimumab subcutaneously at their first treatment visit and at the 2 weeks visit if eligible for a repeat injection. Follow up will be every 2 days the first week then one week later and after that every 4-week intervals for total of 26 weeks.
Intervention Details:
* Systemic adalimumab: Subcutaneous injection of 40 mg adalimumab (Humira) given every 2 weeks.
* Local adalimumab: Intravitreal injection of 1.5mg/0.03ml adalimumab given at zero, 2 weeks, and then every 4 weeks.
Pre-treatment work up
Patients will undergo a comprehensive eye exam:
* Visual acuity, slit-lamp examination of the anterior segment, dilated fundus examination, electroretinography (ERG) and fluorescein angiography (FA).
* Central macular thickness of all eyes will be measured with ocular coherence tomography before treatment.
* Purified Protein Derivative (PPD), Complete blood count (CBC) and SGPT.
Post-injection follow-up
* Patients will be followed up every 2 days during the first week then one week later and after that every 4-week intervals.
* On follow up visits, if deterioration in vision of two or more ETDRS lines or worsening of ocular inflammation by more than 1+ cells/haze is detected at any visit, patients will be removed from the study and receive appropriate treatment. Otherwise, if vision was stable or improved and/or inflammation is same or better, patients will be re-injected.
* Follow up is for 26 weeks.
* OCT and fluorescein angiography each visit.
* ERG will be performed at baseline and 26 weeks.
* Blood studies (CBC and SGPT) will be performed at baseline, 14 weeks and at 26 weeks.
* Injections would be delayed if a patient has an acute infection and would be given when it subsides.

- Target Recruitment
- 32
-
Subject is ≥ 18 years of age.
-
Subject is diagnosed with non-infectious intermediate-, posterior-, or pan-uveitis.
-
Subject must have active disease at baseline as defined by the presence of at least 1 of the following parameters in at least one eye despite at least 2 weeks of prednisone ≥ 10 mg/day (or oral corticosteroid equivalent):
- Active, inflammatory, chorioretinal and/or inflammatory retinal vascular lesion
- ≥ 1+ anterior chamber cells (Standardization of Uveitis Nomenclature [SUN] criteria)
- ≥ 1+ vitreous haze (National Eye Institute [NEI]/SUN criteria)
-
Subject with documented prior adequate response to oral corticosteroids (equivalent of oral prednisone up to 1 mg/kg/day).
-
If subject is on prednisone >=10 mg (or corticosteroid equivalent) at baseline, the dose has not been increased or decreased in the past 14 days.
-
No increase in the immune modulatory therapy in the past three months
-
Negative PPD test.
-
Positive PPD test on anti Tb medications.
- Subject with isolated anterior uveitis.
- Subject with confirmed or suspected infectious uveitis, including but not limited to infectious uveitis due to TB, cytomegalovirus, lyme disease, toxoplasmosis and herpes simplex virus (HSV).
- Subject with serpiginous choroidopathy.
- Subject with corneal or lens opacity that precludes visualization of the fundus or that likely requires cataract surgery during the duration of the trial.
- Subject with corneal or lens opacities that preclude the evaluation of the vitreous haze.
- Subject with uncontrolled high intraocular pressure of ≥ 25 mmHg on maximal therapy.
- Subject with intermediate uveitis and symptoms and/or MRI findings suggestive of a demyelinating disease such as multiple sclerosis. All subjects with intermediate uveitis must have had a prior brain MRI at time of or after diagnosis of intermediate uveitis.
- Subject has received glucocorticosteroids implant (Retisert®), or Ozurdex within 6 months prior to baseline visit.
- Subject has received intraocular or periocular corticosteroids or intravitreal methotrexate within 90 days prior to Baseline visit.
- Subject with proliferative or severe non-proliferative diabetic retinopathy.
- Subject with neovascular/wet age-related macular degeneration
- Subject with abnormality of vitreo-retinal interface (i.e., vitreomacular traction, epiretinal membranes, etc.) with the potential for macular structural damage independent of the inflammatory process.
- Subject with a systemic inflammatory disease and requires additional therapy with a systemic immunosuppressive agent at the time of study entry.
- Subjects with history of active or latent Mycobacterium tuberculosis documented by Purified Protein Derivative (PPD) and chest X-ray and not anti tuberculosis (TB) treatment.
