Plaque Psoriasis | Biological: Secukinumab Radiation: nbUVB Drug: Calcipotriol Drug: Betamethasone | Phase 4 |
The overall study population (Main Study and Mechanistic Sub-study) will consist of a total of 205 male and female patients aged between 18 and 40 years inclusive.
Main Study The Main Study will be conducted in patients with new-onset moderate to severe plaque psoriasis not previously treated with any systemic treatment or phototherapy. A total of 160 patients will be randomized to Arm A1 or Arm B1 in approximately 50 sites worldwide. Since a maximum screening failure rate of 20% is expected, approximately 200 patients will be screened.
Mechanistic Sub-study Any patient who consents can participate in the Mechanistic Sub-study. Patients with new-onset plaque psoriasis will be randomized to Arm A1b, Arm A2, or Arm B1b, those with chronic plaque psoriasis will be randomized to Arm C1 and Arm C2 (15 patients each). For Arm A1b or Arm B1b, the first 15 patients will be included on a first come first serve basis.
Safety assessments :Physical examination, Vital signs, Height and body weight, Laboratory evaluations (hematology, clinical chemistry, high-sensitivity C-reactive protein), Electrocardiogram, Pregnancy, Adverse events
Data Analysis The primary efficacy variable is the proportion of patients who achieve PASI 90 at Week 52. The analysis for the primary objective will be based on the full analysis set. For the primary analysis, the following hypothesis testing will be performed: H01: psec = pnbUVB versus HA1: psec ≠ pnbUVB The primary analysis method for PASI 90 response at Week 52 will use an exact logistic regression model with treatment as an explanatory variable and baseline PASI score as covariate. The key secondary variable is the proportion of all randomized patients who achieve PASI 90 at Week 104. In order to reduce selection bias, all patients who do not achieve PASI 90 at Week 52 will also be included in the analysis at Week 104 using the PASI improvement obtained at Week 104 only.
For the key secondary analysis, the following hypothesis testing will be performed:
H02: p*sec = p*nbUVB versus HA2: p*sec ≠ p*nbUVB

Arm | Intervention/treatment |
---|---|
Experimental: A1
80 patients (65 in Arm A1a and 15 in Arm A1b) with new-onset psoriasis will receive 300 mg secukinumab by s.c. injection at baseline, Weeks 1, 2, 3, 4 and then every 4 weeks until Week 48 inclusive.
|
Biological: Secukinumab
Secukinumab (AIN457) 300 mg will be administered in an open-label fashion according to label as 2 s.c. injections of secukinumab 150 mg (1-mL liquid formulation in a pre-filled syringe). Each 300-mg dose will be provided as 2 pre-filled syringes of 150-mg secukinumab in a single box. Each syringe is labeled as AIN457 150 mg/1 mL. |
Active Comparator: B1
80 patients (65 in Arm B1a and 15 in Arm B1b) with new-onset psoriasis will receive 1 or 2 cycles of nb-UVB of 12 weeks each with a maximum break of 28 weeks between cycles (patients with PASI 90 at Week 40 will not receive a second treatment cycle).Only during the first 4 weeks of each cycle, nb-UVB treatment should be applied in combination with topical calcipotriol 50 μg/g and betamethasone 0.5 mg/g.
|
Radiation: nbUVB
Narrow-band UVB applied in 1 or 2 cycles, each comprising a period of 12 weeks with 2 to 3 treatment sessions per week totaling 24 to 36 sessions per cycle. The application will be performed according to the investigational site's protocol, taking into account the patient's skin type. A maximum dose of 3 J/cm2 on the body and 1 J/cm2 on the face is recommended Drug: Calcipotriol Its a topical treatment for Psoriasis. the concentration it is used is 50mcg/g Drug: Betamethasone this is topical cream which is used in 0.5mg/g concentration |
Experimental: A2
secukinumab 300 mg s.c. administered at baseline, once weekly at Weeks 1, 2, 3 and 4; and thereafter every 4 weeks until Week 100 inclusive (last dose administered at Week 100)

- The primary efficacy variable is the proportion of patients who achieve Pain Assessment Severity Index (PASI) 90 at Week 52. PASI is measured by dermatologist usung a PASI measurement scale. [ Time Frame: 52 weeks ]To demonstrate that early treatment with secukinumab 300 mg s.c. (Arm A1) is superior to standard of care treatment with nb-UVB (Arm B1) in patients with new-onset moderate to severe plaque psoriasis with respect to patients achieving ≥ 90% improvement (reduction) in psoriasis area and severity index (PASI 90) response at Week 52.
- The key secondary variable is the proportion of all randomized patients who achieve PASI 90 at Week 104 [ Time Frame: 104 weeks ]To evaluate the superiority of early treatment with secukinumab (Arm A1) versus nb-UVB (Arm B1) based on the proportion of all randomized patients who achieve at least PASI 90 at Week 104.
