Background summary
Psoriasis is a chronic immunologic disease characterized by marked inflammation
and thickening of the epidermis, resulting in thick, scaly plaques involving
the skin. It affects 1-3% of the general population with North America and
Europe having the highest disease prevalence. There are different forms of
psoriasis which are classified by de cutaneous presentation.
Psoriasis in childhood and adolescents most commonly manifests as plaque and
guttate psoriasis. The most common type of Psoriasis seen among very young
children is napkin psoriasis/psoriatic diaper rash. There is controversy,
however, whether or not this is true psoriasis or whether it represents other
dermatologic conditions.
The most commonly used topical therapies in children include corticosteroids,
calcipotriol and tazarotene, salicylic acid, tar and anthralin.
Systemic treatments include among others cyclosporin A and methotrexate (MTX).
In addition there are the TNF-alpha inhibitor. Data have indicated that
inhibitors of TNF-alpha are efficacious in treating psoriasis in adults.
Adalimumab is a recombinant human immunoglobin (IgG1) monoclonal antibody
containing only human peptide sequences. Adalimumab binds with high affinity
and specificity to soluble TNF-alpha, but not to TNF-beta. Less side effects
and an extended response to treatment are expected because adalimumab is
completely human. This study will be performed with pediatric patients.
Study objective
The objectives of this study are to determine the safety and efficacy of two
doses of adalimumab versus MTX in paediatric subjects with chronic plaque
psoriasis, to determine the time to loss of disease control and the ability to
regain response upon retreatment, and to examine the pharmacokinetics and
immunogenicity of adalimumab following SC administration in this subject
population.
Study design
A multi-centre study
Intervention
The study consists of four periods, period A, B,C, and the
-In Period A the subjects will be randomized into three groups in a 1:1:1
ratio. These subjects receive a standard dose of adalimumab (0,4 mg/kg up to a
maximum of 40 mg) every other week and weekly MTX placebo , a low dose of
adalimumab (0.2 mg/kg up to a maximum of 20mg) every other week and weekly MTX
placebo or weekly MTX (0,1 mg/kg at baseline and 0,4 mg/kg after obtaining
acceptable lab results up to 25mg/wk) and adalimumab placebo every other week.
Period A has a duration of 16 weeks and up to week 8 there is the option of an
early escape to Period D.
-Subjects with a good response in Period A (PASI 75 and PGA 0, 1) will enter
Period B and will be withdrawn form active therapy. The subjects without a good
response in Period A will enter Period D. Period B has a duration of up to 36
weeks. Subjects who experience loss of disease control will enter Period C.
Subjects who do not experience loss of disease control during Period B will
enter Period D without medication.
-Subjects who experience loss of disease control in Period B will enter Period
C. Subjects who received the standard dose of adalimumab at the beginning of
the study will also receive this during Period C, the subjects who received the
low dose of adalimumab at the beginning of the study will also receive this
during Period C and subjects who received MTX at the beginning of the study
will receive the standard dos of adalimumab. Period C has a duration of 16
weeks. After this Period all subjects will enter Period D.
-Period D has a duration of 52 weeks and is the Follow up period.
Subjects who transfer from Period A directly to Period D receive the open label
standard dose of adalimumab. Subjects who transfer from Period B to Period D
will not receive medication unless they experience loss of disease control in
Period D. In this case, they will receive the blinded standard dose of
adalimumab if they received the standard dose of adalimumab or MTX in Period A.
If they received the low dose of adalimumab in Period A, they will also receive
the blinded low dose of adalimumab in Period D.
Subjects who transfer from Period C to Period D will continue with the
(blinded) dose they received in Period C. Subjects who experience loss of
disease control in Period D will have the option to receive open label standard
dose of adalimumab.
Study burden and risks
The subjects will take part in the study for a minimum of 56 weeks (based on a
minimum of 4 weeks in Period A and a maximum of 52 weeks in Period D). The
maximum time in the study will be 120 weeks (based upon a subject losing
control of disease at Week 36b and completing all other study periods).
During the screening visit a PPD (Mantoux) or QuantiFERON - TB test will be
done. If the test result is positive, chest x-rays will also be done. The
subject will be exposed to a small amount of radiation during the x-rays of the
chest. This radiation is not considered to be a significant risk.
Blood samples will be taken during the study in Period A (Week 0a, 1a, 4a, 8
16a), Period B (Week 4b, 12b, 16b), Period C (Week 0c 4c, 11c) and Period D
(Week 0d, 4d, 16d, 52d).
Urine samples will also be taken during screening, Period A ( Week 0a, 16a),
Period C (Week 0c), Period D (Week 0d, 4d, 16d, 52d). Furthermore, If a
subjects decides to stop participating in the study, blood will be drawn and
urine will be collected during the last visit (early termination visit).
Blood will be drawn from subjects who can become pregnant during screening for
the pregnancy test. During all other visits, urine will be taken for the
pregnancy test.
The subjects will also be asked to complete the CDLQI, PedsQL and CDI:S
questionnaires during Period A (Week 0a, 4a,8a, 16a), all visits during Period
B, Period C (Week 0c, 1c, 4c 8c, 11c), Period D (0d, 1d, 4d, 8d, 11d) and
during the early termination visit if the subject decides to stop participating
in the study.
The subject may experience adverse events when the study drug is used. The most
common adverse events of adalimumab were reactions at the injection site.
Subjects suffered from redness, itching, bruising, pain and/or swelling of the
injection site. Most injection site reactions were described as mild and most
of them disappeared without having to stop the administration of study
medication.
Other frequently reported side effects (rate of >= 5 %) of adalimumab in
subjects participating in the clinical studies in order of decreasing frequency
are: nasopharyngitis, upper respiratory infection, headache, nausea,
bronchitis, diarrhea, cough, sinusitis, influenza (flu), hypertension (increase
in blood pressure), urinary tract infection, back pain, and rash.
Men and women who are sexually active should use a reliable contraceptive
method as described in the protocol. The use of certain medications is not
permitted if the subject is participating in the study, these medications are
listed in the protocol.
