An Open Label, Multi-centered, Randomized Phase 2 Study to Evaluate the Safety, Tolerability and Bioactivity of Subcutaneous ACTH GeL in PAtients With Scleritis: The ATLAS Study

ATLAS study is a clinical trial to evaluate the potential role of subcutaneous
adrenocorticotropic hormone (ACTH) gel in the management of non-infectious scleritis.

Specifically, the ATLAS Study aims to evaluate the safety, tolerability and effect of 2
different dose regimens of ACTH gel administered by subcutaneous (SC) injection in patients
with scleritis, over a period of 12 months.

Scleritis is an inflammatory disease affecting the sclera (white outer coating of the eye),
which causes blurring of vision, redness, tearing and painful ocular inflammatory episodes in
one or both eyes. Scleritis may results in vision threatening ocular complications, if left
untreated. Treatment of scleritis is usually chronic and requires systemic therapy with
non-steroidal anti-inflammatory drugs, corticosteroids and immunosuppressive therapy. Due to
its treatment resistance nature, scleritis remains a therapeutic challenge for many
ophthalmologists.

H.P. Acthar Gel (ACTH Gel) is a highly purified preparation of adrenocorticotropic hormone
(ACTH) in a gel that is designed to provide extended release of the ACTH following injection.
It is a FDA approved treatment for flares or on a regular basis (maintenance) in people with
systemic lupus erythematosus (lupus), infantile spasms, adults with acute relapses or flares
of multiple sclerosis (MS), patients with kidney diseases, among other indications. ACTH Gel
is also approved for a wide range of allergic and inflammatory diseases of the eye.

Given the established role of inflammation in the pathogenesis of scleritis and the
anti-inflammatory effects of ACTH Gel treatment by blocking various inflammatory pathways, a
beneficial outcome could be anticipated from ACTH Gel treatment in patients with scleritis.

ATLAS is an Investigator-initiated, open-labelled, multi-center, randomized, phase II
clinical trial, to evaluate the effect of two dose regimens of subcutaneous ACTH gel in
subjects with non-infectious anterior scleritis over a period of 12 months (52 weeks), with
the primary endpoint at month 4 (week 16). ATLAS study will be conducted at up to 6 clinical
sites in USA. The study will be coordinated by the Ocular Imaging Research and Reading Center
(OIRRC), which will serve as the coordinating and reading center for the ATLAS Study.

The ATLAS Study aims to evaluate the potential role of subcutaneous adrenocorticotropic
hormone (ACTH) gel, in the management of non-infectious anterior scleritis. Specifically, the
ATLAS Study aims to evaluate the safety and tolerability of 2 different dose regimens of ACTH
gel administered by subcutaneous (SC) injection in patients with non-infectious anterior
scleritis and to evaluate the bioactivity of 2 different dose regimens of ACTH gel
administered by SC injection in patients with non-infectious anterior scleritis.

Scleritis refers to red and painful inflammation, centered in the sclera that may involve
adjacent ocular structures including the cornea, episclera and uvea. Scleritis may results in
vision threatening ocular complications (corneal ulceration, cataract, glaucoma, retinal
detachment, choroidal effusion) and subsequent blindness. Up to 50% of patients with
scleritis have an associated systemic inflammatory disorder, such as sarcoidosis, rheumatoid
arthritis, systemic lupus erythematosus, and polyangiitis with granulomatosis. Scleritis is
classified based on the anatomic site, as anterior or posterior, with 90% of cases anterior.
Anterior scleritis may manifest as necrotizing or non-necrotizing. Non-necrotizing,
noninfectious scleritis is the most prevalent form. The course of scleritis is usually
chronic, similar to uveitis, and requires systemic therapy with non-steroidal
anti-inflammatory drugs and glucocorticoids, along with immunosuppression, as steroid-sparing
therapy. Due to its treatment resistance nature, scleritis remains a therapeutic challenge
for many ophthalmologists. The ultimate goal is to control the inflammation, which serves as
the cornerstone of the scleritis pathophysiological basis.

Adrenocorticotropic hormone (ACTH) is a member of a group of peptide hormones, called
melanocortins (MCs). ACTH is released from the pituitary gland and acts primarily on the
adrenals to stimulate and regulate steroid hormones production. It has been demonstrated that
MCs can be produced by immune cells at the inflammation site, which created a special
interest in immunomodulatory properties of these peptides. Latest evidence proposes other
anti-inflammatory mechanisms of ACTH actions in addition to steroidogenesis, including
leukocyte transmigration inhibition, cytokine synthesis reduction and generation of
anti-inflammatory signals locally at the inflammation site. ACTH gel has been reported to be
effective in various systemic inflammatory diseases including nephrotic syndrome, multiple
sclerosis, opsoclonus myoclonus,dermatomyositis and polymyositis. These reports also include
cases that were resistant to steroids and other immunomodulatory drugs, supporting the
immune-modulating properties of ACTH. H.P. Acthar® Gel (Repository Corticotropin Injection,
Mallinckrodt Pharmaceuticals) is a 39-amino-acid, pituitary-derived ACTH analogue. ACTH gel
has been demonstrated to have additional therapeutic effects on the humoral immune system,
independent of its role in the adrenal steroidogenesis regulation. It is approved by the US
FDA for treatment of a number of inflammatory conditions, including multiple sclerosis,
rheumatic and collagen disorders, as well as ophthalmologic diseases, such as ocular allergy,
keratitis, uveitis and optic neuritis. However, due to the scarcity of data from clinical
studies, many physicians are unaware of ACTH gel as a treatment option for inflammatory
diseases.

The proposed study aims to evaluate the potential role of ACTH gel in the management of
non-infectious anterior scleritis. Given the established role of inflammation in the
pathogenesis of scleritis and the ability of ACTH to bind to cellular and tissue melanocortin
receptors, thus blocking various inflammatory pathways, a beneficial outcome could be
anticipated from ACTH analogue in patients with scleritis.

Thirty (30) subjects with non-infectious anterior scleritis will be enrolled in the study.

The primary endpoint of the study will be at week 16, with an active, as-needed treatment
extension phase from week 17 to week 52.

All study participants will be randomized (1:1) at their Baseline (BL) visit (visit 2) to one
of the two treatment arms. All subjects will be started on oral corticosteroids (at a maximum
dosage of 1 mg/kg of prednisone or equivalence a day) at the screening visit which will
continue to be administered at the same dose throughout the screening period until BL/Visit
2. Steroid dose will be tapered from BL/Visit 2 onwards until week 9 (Visit 5). If the
scleritis is still greater than 0.5+ on the grading scale, the investigators have the
discretion to continue on the tapering course of steroid while the subjects are also being
treated with ACTH gel.

The two treatment arms are as follows:

1. Mandatory 80 U twice weekly treatment with SC ACTH gel, starting at the Baseline visit
(Day 0) until end of week 16.

2. Mandatory 80 U thrice weekly treatment with SC ACTH gel, starting at the Baseline visit
(Day 0) until end of week 16.

Starting at week 17, treatment regimen will be determined according to clinical response to
treatment as follows:

1. No evidence of active disease/disease resolved - treatment dose will be reduced to 80 U
once a week with SC ACTH gel.

2. Evidence of disease improvement, but still active/partial response - ACTH treatment will
continue alone at the pre-assigned treatment dose. Steroids will not be added to the
treatment due to several side effects of the combination of the drugs.

3. No evidence of improvement/disease progression - treatment with ACTH gel will be
discontinued and rescue therapy will be initiated as per investigator based on standard
of care.

At the primary end point (week 16) and at the end of follow-up period (week 52) efficacy will
be assessed by standard ophthalmic examination procedures and response to treatment, which
will be graded according to established scleritis grading scale. Evaluation of response will
be based on changes in scleral inflammation grade at various time points during the study,
changes in pain grade scale at various time points during the study, changes in the dosage of
prednisone required to maintain disease quiescence and stability and changes on ancillary
testing such as FA, OCT, among others. Retreatment will be offered to study subjects who have
demonstrated any level of response during the first 16 weeks and who meet any of the
Retreatment Criteria listed below. Subjects receiving retreatment will receive the dose that
was assigned to them at randomization. There is no placebo arm in this study.

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.

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:
