Brief Summary

This study will evaluate the Efficacy and Safety of Infliximab versus Cyclophosphamide in Subjects with Idiopathic Refractory Scleritis. The term scleritis describes a chronic inflammation that involves the outermost cost and skeleton of the eye. Scleritis is classified anatomically as either anterior or posterior based on the principal location of the inflammation. Thirty to forty percent of scleritis cases are associated with systemic autoimmune conditions including rheumatoid arthritis and granulomatosis with polyangiitis. Infectious causes including herpes virus and varicella zoster account for 5 to 10% of patients. The remaining 50% of cases are classified as idiopathic. CIRIS, is the first prospective randomized, head to head study, comparing infliximab to cyclophosphamide in refractory idiopathic scleritis. There is no firm evidence or randomized controlled trials directly addressing the best biologic agent in severe and refractory idiopathic scleritis. If left untreated or insufficiently treated, scleritis can progress to peripheral ulcerative keratitis, uveitis and glaucoma. Visual loss occurs in approximately 10% of patients with anterior scleritis and in up to 75% of patients with posterior scleritis. The incidence of burden in ocular inflammation (uveitis and scleritis) has been dramatically reduced in the recent years with the use of biologics, raising the question of whether these compounds should be used earlier in the treatment of severe non infectious scleritis. Contrasting with other immunosuppressors, cyclophosphamide and infliximab act rapidly and are highly effective in steroid's sparing. Despite a strong rationale, these compounds are not yet approved in idiopathic refractory scleritis, which guarantees the innovative nature of this study that aims selecting or dropping any arm when evidence of efficacy already exists.

Outcome Measures

Primary Outcomes (1)

• percentage of patients with resolution (score=0) of the scleral inflammation and with a prednisone dose lower than 0.1 mg/kg/day

  Scleritis will be graded and scored according to the grading system defined by Sen for sclera inflammation (gradings from 0 to 4): these findings will be documented by drawings, photography or both for central review.

  Week 20

Secondary Outcomes (16)

• percentage of patients with a decrease of at least 2 in sclera inflammation with a prednisone dose lower or equal to 0.1 mg/kg/day.

  Week 20

• Mean change in sclera inflammation from baseline to Week 20.

  Week 20

• Time to response onset (total resolution in sclera inflammation).

  Week 26

• Mean change in Best corrected visual acuity

  Week 20

• percentage of patients meeting targets: ≤ 0.1 mg/day prednisone

  Week 20

Study Arms (2)

infliximab

EXPERIMENTAL

Patients will receive prednisone and infliximab (5 mg/kg at week 0, 2, 6, 11 and 16 as an intravenous (IV) infusion) in association with low-dose methotrexate (10 mg/week) for 16 weeks.

Drug: Infliximab

cyclophosphamide

EXPERIMENTAL

Patients will receive prednisone and cyclophosphamide intravenously (700 mg/m2 every 4 weeks intravenously) (n=25) for 16 weeks.

Drug: Cyclophosphamide

Interventions

Infliximab DRUG

Patients will receive prednisone and infliximab (5 mg/kg at week 0, 2, 6, 11 and 16 as an intravenous (IV) infusion) in association with low-dose methotrexate (10 mg/week) for 16 weeks.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Provide written informed consent prior to the performance of any study-specific procedures
• Male or female, subject aged \> or = 18 at Screening
• Weight 40 - 120 kg at Screening
• Diagnosis of anterior idiopathic scleritis or anterior and posterior idiopathic scleritis at least one eye. Scleritis is classified anatomically as anterior based on the principal location of the inflammation. Clinically, anterior scleritis can be divided into diffuse, nodular or necrotizing types.
• Active disease: Currently uncontrolled scleritis disease. Uncontrolled scleritis disease is defined as (at least) a 2 in sclera inflammation, according to the grading system defined by Sene for sclera inflammation (gradings from 0 to 4).
• Refractory disease: At screening, subjects must be receiving oral corticosteroids (\>10 mg/day prednisone equivalent and \<80 mg/day) and at least one other immunosuppressive for more than 4 months (azathioprine, methotrexate, mycophenolate mofetyl, cyclosporine, leflunomide) or be intolerant to such immunosuppressive therapies.
• Topical corticosteroids and/or NSAIDs are permitted provided the dose regimen has been stable for 2 weeks prior to Screening and remains stable throughout the study. Topical treatment for cycloplegia is permitted.
• Page 40 sur 129
• Chest X-ray results (postero-anterior and lateral) within 12 weeks prior to the randomization visit with no evidence of active Tuberculosis, active infection, or malignancy.
• For female subjects of child-bearing age, a negative serum pregnancy test. A woman is considered of childbearing potential, i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient (definition of the Clinical Trial Facilitation Group).
• For subjects with reproductive potential, a willingness to use adequate contraceptive measures to prevent the subject or the subject's partner from becoming pregnant during the study. For women in period of childbearing adequate contraceptive measures include hormonal methods used for two or more cycles prior to Screening and 6 months after the last dose treatment should be used (e.g., oral contraceptive pills, contraceptive patch, or contraceptive vaginal ring), barrier methods (e.g., contraceptive sponge, diaphragm used in conjunction with contraceptive foam or jelly, or condom used in conjunction with contraceptive foam or jelly), intrauterine devices (IUD), sterilization (e.g., tubal ligation or a monogamous relationship with a vasectomized partner), and abstinence. For men who are sexually active with a women in period of childbearing adequate contraceptive measures from screening to 6 months after the last dose treatment should be used (For men: barrier methods (condom used in conjunction with contraceptive foam or jelly), sterilization (vasectomy) and abstinence. For his partner: hormonal methods (e.g., oral contraceptive pills, contraceptive patch, or contraceptive vaginal ring), barrier methods (e.g., contraceptive sponge, diaphragm used in conjunction with contraceptive foam or jelly), intrauterine devices (IUD), sterilization (e.g., tubal ligation)).
• A negative QuantiFERON®-Tuberculosis (TB) test result or, in the event that their QuantiFERON®-TB test result at Screening is positive, all subjects must agree to complete an INH treatment course of at least 6 months.
