Daclizumab for relapsing remitting multiple sclerosis. [2010.06.16]
CONCLUSIONS: Although studies examining daclizumab for relapsing remitting multiple sclerosis were located, methodologic limitations resulted in the exclusion of all studies. Some of the studies were labelled as crossover trials, however they only compared the effect of different interventions for the same individual. The true randomized crossover trial should compare the effect of different groups, which receive the same intervention, only with the difference in sequence. In other words, the crossover comparison should be between the different groups, rather than on the individual between pretreatment and post treatment. At the same time, all the individuals should be randomly allocated to different groups. There was also a rigorous randomized controlled trial, but the follow-up was shorter than one year (only 44 weeks). In general, daclizumab is safe and well tolerated in combination of interferon treated multiple sclerosis population. Improvements in methodology in future studies are required for meaningful synthesis of data.
Clinical Trials Related to Zenapax (Daclizumab)
Anti-Tac for Treatment of Leukemia [Completed]
The purpose of the study was to determine: (1) the toxicity and maximum tolerated dose
(MTD) of humanized anti-Tac (daclizumab), (Zenapax(Registered Trademark)) in patients
with adult T-cell leukemia/lymphoma (ATL); (2) to define the dose of Zenapax(Registered
Trademark) required to saturate interleukin 2 receptor alpha (IL-2R) alpha in patients with
ATL; (3) determine the clinical response to humanized (Hu) anti-Tac (Zenapax(Registered
Trademark) of patients with Tac-expressing adult T-cell leukemia; and (4) determine the
serum dieaway curve (pharmacokinetics) of infused humanized (Hu)-anti-Tac in patients who
have ATL. This study represented an extension of Metabolism Branch National Cancer
Institute (NCI) protocols utilizing modifications of the original murine anti-Tac monoclonal
antibody (mAb) developed by our group for the treatment of ATL. The scientific basis for
these therapeutic studies is that the leukemic cells of patients with ATL express abnormally
high levels of the Tac antigen (IL-2R alpha) on their surface whereas resting normal cells
including normal T-cells of the patients do not. One presumed mode of action of Hu-anti-Tac
in the treatment of ATL involves the interruption of the interaction of interleukin 2 (IL-2)
with its growth factor receptor. To be effective in this goal we must maintain saturation
of the IL-2 receptors (IL-2R) with humanized anti-Tac thereby preventing IL-2 mediated
proliferation and yielding cytokine deprivation and apoptotic cell death of the leukemic
cells. Eligible patients with ATL were treated with escalating doses of Zenapax(Registered
Trademark) between groups in the Clinical Center of the National Institutes of Health (NIH).
Groups of patients received sufficient Zenapax(Registered Trademark) to yield saturation of
the IL-2 receptor for a period of 17 weeks. Clinical response was evaluated using routine
immunological and clinical evaluation and by monitoring the saturation of the IL-2R and the
absolute number of residual circulating malignant cells by fluorescence activated cell
sorting (FACS) analysis using two fluorochrome-labeled non-crossreacting antibodies to the
IL-2 receptor, anti-Tac and 7G7/B6, as well as antibodies to cluster of differentiation 3
(CD3), cluster of differentiation 4 (CD4), cluster of differentiation 7 (CD7), and cluster
of differentiation 8 (CD8). Furthermore, responses were evaluated in patients with leukemia
by Southern blot analysis of the arrangement of the T-cell receptor genes and human
T-lymphotropic virus type 1 (HTLV-I) integration. Finally, in select patients, to define
the pharmacokinetics of the therapeutic antibody, had planned to monitor the serum levels of
the infused Hu-anti-Tac (Zenapax(Registered Trademark)) as a function of time. This study
is an essential element of our program involving IL-2R-directed therapeutic studies. If as
anticipated the therapy with humanized anti-Tac yields some partial and complete remissions
in patients with ATL, we will propose that it be used as a single agent for patients with
smoldering and chronic ATL and in association with chemotherapeutic agents to provide a
novel approach for the treatment of acute and lymphoma forms of ATL. We also plan a future
clinical trial where tentative plans also had been made to evaluate the efficacy and
toxicity in ATL patients of saturating doses of Zenapax(Registered Trademark) as compared to
identical doses of Zenapax(Registered Trademark) given in association with (90)Y-armed
7G7/B6, a non-competing antibody to IL-2R alpha or in combination with chemotherapy.
A Study to Determine Whether Therapy With Daclizumab Will Benefit Patients With Bone Marrow Failure [Terminated]
Participants in this study are suffering from rare and serious blood disorders. In aplastic
anemia, the bone marrow stops producing red blood cells, platelets, and white blood cells.
In pure red cell aplasia, the bone marrow stops producing red cells, and in amegakaryocytic
thrombocytopenic purpura, the bone marrow stops producing platelets.
Current treatment approaches for these disorders include bone marrow transplant and/or
immunosuppression. However, bone marrow transplant is not always possible, and
immunosuppression has serious side effects.
This study will investigate whether daclizumab can be used to treat these disorders.
Daclizumab is a genetically engineered human antibody that blocks the interleukin-2 receptor
on immune cells. It has been used successfully in many transplant patients to reduce the
rate of organ rejection.
Participants will undergo a complete history and physical examination. A bone marrow
aspiration and biopsy will be performed to confirm the type of bone marrow failure. About 5
tablespoons of blood will be drawn for baseline tests and research purposes. Daclizumab
will be administered every 2 weeks by vein in a 30-minute infusion. The first dose will be
given at NIH and the next four may be given at NIH or by the participant's primary
hematologist. The treatment will last 8 weeks. Participants must also see their referring
physician or NIH physicians every 2 weeks for blood counts. In the fourth and eighth weeks
of the study and at the 3-month follow-up visit, 2 tablespoons of blood will be drawn at
NIH. At the 1-month follow-up visit to NIH, 5 tablespoons of blood will be drawn and
another bone marrow aspiration and biopsy performed.
Risks from bone marrow aspiration and biopsy and blood draws include discomfort. Daclizumab
is usually well-tolerated; however, it may weaken immunity against certain bacteria and

Infliximab, Sirolimus and Daclizumab to Treat Age-Related Macular Degeneration [Completed]
This study examined whether the anti-inflammatory medicines infliximab, sirolimus or
daclizumab, when given with a participant's current therapies, would prevent the growth of
new blood vessels in the eye in participants with age-related macular degeneration (AMD).
Participants 55 years of age and older with AMD and drusen larger than 63um may be eligible
for this study. Vision in the study eye was between 20/20 and 20/400.
Participants were randomly assigned to one of three treatments - infliximab, sirolimus, or
daclizumab - or to observation only. In addition, participants may have been treated by
their ophthalmologist as needed for their AMD.
Infliximab and daclizumab were given intravenously (through a vein); infusions were given at
enrollment in the study, then at 2 weeks, and then monthly.
Sirolimus was a pill that was taken every other day for the duration of the study. At 6
months, participants were evaluated to see whether continuing treatment would be beneficial.
In addition to treatment or observation, participants underwent the following procedures:
Physical examination at enrollment and 6 months.
Photographs of the back of the eye, fluorescein angiography, indocyanine green angiography
and measurement of retinal thickness at enrollment and months 1, 3 and 6.
- Fluorescein angiography evaluated the eye's blood vessels. A yellow dye was injected
into an arm vein and traveled to the blood vessels in the eyes. Pictures of the retina
were taken using a camera that flashed a blue light into the eye. The pictures show if
any dye has leaked from the vessels into the retina, indicating possible blood vessel
- Indocyanine green angiography identified feeder vessels that may have supplied abnormal
blood vessels. This procedure is similar to fluorescein angiography, but uses a green
dye and flashes an invisible light.
- Optical coherence tomography measures retinal thickness. This test shines a light into
the eye and produces cross-sectional pictures of the retina. These measurements are
repeated during the study to determine whether retinal thickening is getting better or
worse, or staying the same.
Tuberculin skin test and chest x-ray at enrollment and 6 months.
Blood tests at enrollment and months 1, 3 and 6.
