A Phase 2 interventional study of ACTH gel in Uveitis, sponsored by Quan Dong Nguyen. Completed at 7 sites in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-12-17.
Sponsored by Quan Dong Nguyen · Phase 2, Interventional, and Treatment
The study aims to evaluate the potential role of ACTH gel in the management of non-infectious uveitis.
Uveitis is a term used to describe a group of inflammatory disorders involving the uveal tract (iris, ciliary body and choroid). It is amongst the most common causes in the list of preventable cause of blindness in the developed world.
H.P. Acthar Gel is a highly purified sterile preparation of the adrenocorticotropic hormone (ACTH) gelatin to provide a prolonged release after intramuscular or subcutaneous (SC) injection.
ACTH is part of a group of molecules called melanocortins (MC) (ACTH, α, β, γ-MSH) that are produced, in human bodies, by breakdown of a common larger precursor called proopiomelanocortin (POMC). A very well-known anti-inflammatory mechanism of action of ACTH is the production glucocorticoids by stimulating the adrenal glands. ACTH has also been shown to bind with all five melanocortin receptors (MCRs). MCRs have a variety of roles including cortisol production and regulation of immune modulation by ACTH.
ACTHAR is an open-label, multi-center, randomized, phase II study to evaluate the effect of two dose regimens of repeated SC injections of ACTH gel in patients with active non-infectious intermediate, posterior, or pan-uveitis followed over a period of 12 months.
ACTHAR study will be conducted at up to 7 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 ACTHAR Study.
The primary endpoint of the study will be at month 6, with an active, as-needed treatment extension phase from month 6 to month 12.
Thirty-six (36) patients with non-infectious intermediate, posterior, or pan-uveitis will be enrolled and randomized (1:1) to one of the two treatment arms:
Starting at month 6, retreatment will be offered to study subjects who have demonstrated any level of response during the first 6 months and who meet any of these Retreatment Criteria listed below. Patients receiving retreatment will receive the dose that was assigned to them at randomization.
299 studies on the registry are indexed under Uveitis; 32 are open to participants now.
This study's enrollment of 28 is close to the median of 30 across 175 interventional studies indexed under Uveitis.

Inclusion Criteria:
In order to be eligible for the study, patients will be required to meet the criteria of 1 of the 3 following disease cohorts:
Exclusion Criteria:
Subjects who have any of the following at the screening visit are not eligible for enrolment in this study:
Any significant ocular disease that could compromise vision in the study eye. These include, but are not limited to:
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:
Any previous treatment with alkylating agents such as chlorambucil, or with total lymphoid irradiation.
Exclusions for General Safety:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.
Criteria about it usually ask for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Corticosteroids (steroids)
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
