- Participant is not currently pregnant or lactating.
- Participant with reproductive potential and who is sexually active agrees to use acceptable birth control methods throughout the course of the study and for 6 months after completion of the protocol treatment period. (Acceptable methods must be discussed by the participant with the Investigator, and may include use of condoms, diaphragms, IUDs, progesterone implants or injections, or double barrier methods.)
- Participant, or their parent or guardian if younger than 18 years at enrollment, is able to understand and sign an approved consent form before entering into the study; any minor participant must also sign an assent if required by the local Institutional Review Board or Independent Ethics Committee (IRB/IEC).
Who cannot join
- Participants under the age of 6 years.
- Participants who have received previous treatment with an IL-2 directed monoclonal antibody.
- Participants who are currently enrolled in another clinical trial or who are using a therapy for a non-uveitis condition that would likely affect immune responses or interfere with trial logistics, or who have received any investigational therapy within the 30 days prior to enrollment.
- Participants with a history or diagnosis of Behcet's disease (since tapering or withdrawal of concomitant immunosuppressive medications is not a standard of care for Behcet's patients) or a primary diagnosis of anterior uveitis (e.g., juvenile rheumatoid arthritis (JRA) or HLA-B27 associated uveitis, ocular conditions usually treated with local and not systemic medications).
- Participants with a significant, systemic infection requiring medical treatment at the time of enrollment.
- Participants with a history of cancer (other than a non-melanoma skin cancer or in situ cervical cancer) diagnosed within the past 5 years.
- Participants with non-ocular, medically significant co-morbid conditions that impair normal activities, require immunosuppression, or who have a condition with a prognosis that indicates a significant risk of disability or death if the condition were to continue or be exacerbated during the study period, or a medical condition that would likely have an impact on the participant's ability to comply with the visit schedule. Such conditions may include, for example, recent heart attack, significant COPD, brittle diabetes, kidney disease, severe emphysema, organ transplant (requiring corticosteroids or other immunosuppressive medications), hepatitis or other liver disease, or uncontrolled psychiatric illnesses.

About this study
Official title: Evaluation of Subcutaneous Daclizumab Treatments in Patients With Non-Infectious Sight-Threatening Uveitis: A Multicenter, Open-Label, Phase II Study
This study will examine the safety and effectiveness of a monoclonal antibody called daclizumab in treating uveitis, an eye inflammation. Monoclonal antibodies are genetically engineered proteins made in large quantities and directed against a specific target in the body. Daclizumab is designed to prevent a specific chemical interaction needed for immune cells called lymphocytes to produce inflammation. In an ongoing NIH study of 10 adults with uveitis, 8 patients were able to decrease corticosteroids and other immunosuppressive medicines they were taking while receiving daclizumab for months or even years. The study will be conducted at three different sites, including the NIH Clinical Center.
Patients 6 years of age and older with non-infectious uveitis of at least 3 months' duration who require treatment with immune suppressing medicines, such as prednisone, cyclophosphamide, cyclosporine, azathioprine, methotrexate, or others, may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood tests, complete eye examination, and a questionnaire about the patient's vision and daily activities.

Participants will come to the study center every 2 weeks for treatment and evaluation. Daclizumab treatments are given by injection under the skin, usually in the arm. Patients will receive a maximum of 28 treatments over a 1-year period. Treatment may be extended for a few months while other participants reach their 1-year mark. The first two induction treatments are at a higher dose (2 mg/kg of body weight) than the maintenance dose of 1 mg/kg. After the first daclizumab treatment, other uveitis medications will be tapered, one at a time. If the disease remains quiet, these drugs may eventually be stopped completely.
For the first 6 months, all patients will receive daclizumab injections and evaluations every 2 weeks. After that, if other medications have been reduced and vision has remained stable, treatments and evaluations may be spread out to every 3 or 4 weeks. Over time, fewer tests may be required during the biweekly examinations if the patient is doing well, but nearly all the examinations done at screening will be repeated at 3-month intervals. If inflammation or vision loss occurs during drug tapering, appropriate treatment will be administered. If the vision loss is too great, the patient will be treated with steroids or other medicines and taken off the study.
Additional, special tests done at selected study centers include the following:
- Fluorescein angiography: This test is done to check for abnormalities of eye blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken with a special camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible abnormalities.
- Pelvic ultrasound and urine test: These tests are done at enrollment and after 1 year to check the kidneys, lymph nodes, and pelvic area.
- Blood tests: Additional blood tests are done at enrollment and every 3 to 6 months for laboratory and immunology study.
Read the detailed description
Uveitis refers to intraocular inflammatory diseases that are an important cause of visual loss. Standard systemic immunosuppressive medications for uveitis can cause significant adverse effects. Consequently, an effective treatment with a safer side effect profile is highly desirable. Daclizumab is a humanized anti-Tac monoclonal antibody directed against the high affinity IL-2 receptor CD25 or Tac subunit. The IL-2 receptor system plays a central role in the induction of immune responses via activated T and B-lymphocytes, observed both in uveitis animal models and on the surface of human cells in patients with uveitis. Blocking this system impedes immune responses and can inhibit the development of local inflammatory responses. Previous studies using intravenous daclizumab treatments suggest that continuing daclizumab treatments at 1 mg/kg every 2-4 weeks may effectively control uveitis even after the complete withdrawal of standard immunosuppressive medications. Subcutaneous (SC) daclizumab injections at 1 and 2 mg/kg in healthy volunteers are well tolerated and have been shown to produce serum daclizumab trough levels comparable to intravenous treatments.
This is an open-label, multi-center Phase II trial of SC daclizumab designed to provide information on current trial design feasibility as well as preliminary safety and efficacy data on 15 participants at 3 sites who are 6 years of age or older and who require standard systemic immunosuppression to control their non-infectious posterior or intermediate uveitis. The SC daclizumab treatments are given every 2 weeks for up to 6 months unless a safety endpoint requires study exit. A re-induction of SC daclizumab therapy may be permitted after an initial efficacy failure. Therapy begins with two induction treatments at 2 mg/kg (limit of 200 mg), followed by maintenance therapy at 1 mg/kg (limit of 100 mg). Beginning with the first SC daclizumab treatment, the initial immunosuppressive medication load will be tapered in a staggered fashion to a target level of 50% or less of the original dose within an 8 to 12-week period, if tolerated. After a preliminary efficacy evaluation at 12 weeks, further tapering and continued SC daclizumab therapy may continue as clinically indicated through the duration of the trial. The primary efficacy outcome is the maintenance of visual acuity with the simultaneous reduction of original immunosuppressive medication load. Primary safety measures are visual acuity and the occurrence of adverse events. Secondary outcome measures include anterior chamber and vitreous cells, vitreous haze, and questionnaire results.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Mar 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00043667, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
