Brief Summary
Rituximab is a man-made antibody used to treat certain types of cancer. This study will
determine whether rituximab is an effective treatment for adult and pediatric patients with
dermatomyositis or polymyositis.
Study hypotheses: 1) The time to improvement in Group A patients (receiving rituximab first)
will occur significantly earlier than in Group B patients (receiving rituximab later). 2) The
proportion of patients improved at Week 8 of the treatment phase will be significantly
greater in Group A than in Group B.
Detailed Description
Rituximab is a chimeric, murine-human, genetically engineered monoclonal antibody directed
against the CD20 (cluster of differentiation antigen 20) antigen found on the surface of
B-lymphocytes and is known to deplete B cells when administered intravenously. It is approved
to treat non-Hodgkin's lymphoma. Rituximab has been used for autoimmune diseases such as
systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and immune-mediated
hematologic disorders. It has also been studied and used in small numbers of patients with
myositis. This study will evaluate the efficacy of rituximab in treating refractory adult and
pediatric patients with dermatomyositis and adult polymyositis.
A patient's participation in this study will last approximately 45 weeks. At screening,
participants will have a physical exam, muscle strength assessment, an electrocardiogram, and
blood and urine collection; they will also be asked to complete several questionnaires. All
participants will receive 2 infusions of rituximab and 2 infusions of placebo. Participants
will be randomly assigned to one of two groups. Group A will receive rituximab at Weeks 0 and
1 and placebo at Weeks 8 and 9. Group B will receive placebo at Weeks 0 and 1 and rituximab
at Weeks 8 and 9. Each infusion will be given on an outpatient basis over a minimum of
approximately 5 hours' time.
There will be a total of 14 study visits. All participants will visit the outpatient clinic
at selected time points for muscle strength testing, a physical exam, disease activity
measurements, and blood collection. During the study, participants will be monitored closely
for improvement or worsening of their disease and for serious drug related side effects. Some
participants will be asked if they are willing to undergo 2 muscle biopsy procedures, 1 prior
to receiving study medication and 1 after receiving study medication, to determine the
effects of rituximab on muscle tissue.
If a participant is unable to locate a near-by clinical center, the adult and pediatric
centers at the National Institute of Health located in Bethesda, Maryland have funds
available to assist with travel costs.
NIH SUB-STUDY: "Rituximab to Treat Dermatomyositis and Polymyositis"
- This study is currently recruiting patients.
- Sponsored by: National Institute of Environmental Health Sciences (NIEHS)
- Information provided by: National Institutes of Health Clinical Center (CC)
- Expected Total Enrollment: 30
- Study start: October 2006

The NIH sub-study will take advantage of the multi-center core RIM trial to identify changes
in gene expression patterns in muscle, skin, and peripheral blood and the imaging features
and immunopathology of muscle, skin, and peripheral cells before (week 0) and after (week 16)
therapy. These changes will also be correlated with the large number of clinical, laboratory,
and research variables already planned to be collected in the core RIM Study. Furthermore,
knowing specifically which gene expression patterns are altered in resistant patients before
rituximab, and which are changed after rituximab therapy - in conjunction with flow cytometry
of peripheral cells and immunopathology of the tissues - will help in understanding more
about the pathogenesis of myositis and the possible contribution of B lymphocytes and their
subsets.
Patients with dermatomyositis and polymyositis who meet the inclusion/exclusion criteria for
the core RIM trial may be eligible for this sub-study. The following procedures will be
conducted in addition to the core RIM trial procedures during the 13 clinic visits over a
period of 44 weeks:
- Weeks 0, 16: Muscle and skin biopsy (adult only). Small samples of muscle and skin
tissue will be surgically removed for examination under a microscope.
- Weeks 0, 8, 16, 44: Skin evaluation and photography. The effect of the disease on the
skin will be thoroughly evaluated and photographs of any rashes and of the skin around
the nails will be taken.
- Weeks 0, 8, 16, 44: Magnetic resonance imaging (MRI). All participants will have MRI
scans of the skin and of the muscle in the legs. Adults will also have an MRI to examine
blood flow in the muscle.

Conditions
Conditions usually refer to a disease, disorder, syndrome, illness, or injury. In ClinicalTrials.gov,
conditions include any health issue worth studying, such as lifespan, quality of life, health risks, etc.
Interventions
Interventions refer to the drug, vaccine, procedure, device, or other potential treatment being studied.
Interventions can also include less intrusive possibilities such as surveys, education, and interviews.
Study Phase
Most clinical trials are designated as phase 1, 2, 3, or 4, based on the type of questions
that study is seeking to answer:
In Phase 1 (Phase I) clinical trials, researchers test a new drug or treatment in a small group of people (20-80) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
In Phase 2 (Phase II) clinical trials, the study drug or treatment is given to a larger group of people (100-300) to see if it is effective and to further evaluate its safety.
In Phase 3 (Phase III) clinical trials, the study drug or treatment is given to large groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
In Phase 4 (Phase IV) clinical trials, post marketing studies delineate additional information including the drug's risks, benefits, and optimal use.
These phases are defined by the Food and Drug Administration in the Code of Federal Regulations.
