A Trial Comparing the Efficacy of Subcutaneous Injections of Brodalumab to Oral Administrations of Fumaric Acid Esters in Adults With Moderate to Severe Plaque Psoriasis

The primary objective is to demonstrate added benefit of brodalumab versus a selected systemic comparator in treatment of moderate to severe plaque psoriasis in Germany in subjects who have not previously received systemic treatment for psoriasis.

Fumaric acid esters have been selected as the comparator because it is an established systemic treatment of psoriasis in Germany.

Treatment and study plan

Brodalumab

Biological

Brodalumab is a recombinant fully human monoclonal immunoglobulin IgG2-antibody that binds with high affinity to human interleukin 17 receptor A (IL-17RA).

Blocking IL-17RA inhibits IL-17 cytokine-induced responses and results in reduced or normalised inflammation of the skin in subjects with psoriasis.

Other names: Kyntheum®

Fumaric acid esters

Drug

Fumaric acid esters have been used to treat psoriasis since 1959. Systemic therapy with fumaric acid esters is based on an established dosing scheme with a gradual increase to improve tolerability, especially with regards to gastrointestinal side effects.

Other names: Fumaderm®

Primary outcomes

  1. Having Least 75% Lower Psoriasis Area and Severity Index (PASI) Score Relative to Baseline (PASI 75 Response) From Baseline at Week 24

    Time frame: Baseline to Week 24

    The PASI score grades the extent and severity of psoriatic involvement for each of four body regions (head and neck, upper extremities, trunk, and lower extremities) using a 7-point scale for extent of involvement in each body region and 5-point scales for severity of each of the clinical signs redness, thickness, and scalliness in each body region.

    Psoriasis Area and Severity Index is a scale ranging from 0 (no disease) to 72 (maximal disease).

  2. Static Physician's Global Assessment (sPGA) Scale Score of 0 or 1 at Week 24

    Time frame: Baseline to Week 24

    sPGA is a 6-point scale that represents the average lesion severity on the trunk and limbs. The assessment is based on the condition of the disease at the time of evaluation.

    Static Physician's Global Assessment is a scale ranging rom 0 (clear skin) to 5 (severe disease).

Secondary outcomes

  1. Having Least 90% Lower Psoriasis Area and Severity Index (PASI) Score Relative to Baseline (PASI 90 Response) From Baseline at Week 24

    Time frame: Baseline to Week 24

    The PASI score grades the extent and severity of psoriatic involvement for each of four body regions (head and neck, upper extremities, trunk, and lower extremities) using a 7-point scale for extent of involvement in each body region and 5-point scales for severity of each of the clinical signs redness, thickness, and scalliness in each body region.

    Psoriasis Area and Severity Index is a scale ranging from 0 (no disease) to 72 (maximal disease).

  2. Having 100% Lower Psoriasis Area and Severity Index (PASI) Score Relative to Baseline (PASI 100 Response) From Baseline at Week 24

    Time frame: Baseline to Week 24

    The PASI score grades the extent and severity of psoriatic involvement for each of four body regions (head and neck, upper extremities, trunk, and lower extremities) using a 7-point scale for extent of involvement in each body region and 5-point scales for severity of each of the clinical signs redness, thickness, and scalliness in each body region.

    Psoriasis Area and Severity Index is a scale ranging from 0 (no disease) to 72 (maximal disease).

  3. Change From Baseline at Week 24 in PASI Score

    Time frame: Baseline to Week 24

    The PASI score grades the extent and severity of psoriatic involvement for each of four body regions (head and neck, upper extremities, trunk, and lower extremities) using a 7-point scale for extent of involvement in each body region and 5-point scales for severity of each of the clinical signs redness, thickness, and scalliness in each body region. Psoriasis Area and Severity Index is a scale ranging from 0 (no disease) to 72 (maximal disease).

    A negative change in PASI score means that the PASI score was lower at the time of data collection.

  4. Percent Change From Baseline in PASI Score at Week 24

    Time frame: Baseline to Week 24

    The PASI score grades the extent and severity of psoriatic involvement for each of four body regions (head and neck, upper extremities, trunk, and lower extremities) using a 7-point scale for extent of involvement in each body region and 5-point scales for severity of each of the clinical signs redness, thickness, and scalliness in each body region. Psoriasis Area and Severity Index is a scale ranging from 0 (no disease) to 72 (maximal disease).

    A negative value in the percent change from baseline that the PASI score was lower at the time of data collection.

  5. Change From Baseline at Week 24 in Affected Body Surface Area (BSA)

    Time frame: Baseline to Week 24

    The surface area of the participant's hand (palm and fingers) is used as a reference measurement to calculate the percentage of each body region that is affected by psoriasis. One hand is approximately equal to 1% total BSA.

    Furthermore, the complete body surface area (BSA=100%) can be divided into regions that approximates percentages of BSA as follows: head and neck (10%), upper extremities (20%), the trunk including the axillae and groin (30%), and finally the lower extremities, including the buttocks (40%).

    A negative value in the percent change from baseline that the affected BSA was lower at the time of data collection.

  6. Psoriasis Symptom Inventory (PSI) Responder at Week 24 (Total Score ≤ 8, With no Item Scores > 1)

    Time frame: Week 24

    The PSI consists of eight psoriasis-specific questions. Trial participants rated the severity of their symptoms in the last 24 hours from 'not at all' to 'very severe,' ranging from 0 to 4. Total scores range from 0 to 32 with higher scores indicating worse symptoms. PSI response is defined as total score ≤8 and no item score >1. Symptom-free day is defined as having daily total PSI of 0 on that day.

  7. PSI Total Score of 0 at Week 24

    Time frame: Week 24

    The PSI consists of eight psoriasis-specific questions. Trial participants rated the severity of their symptoms in the last 24 hours from 'not at all' to 'very severe,' ranging from 0 to 4. Total scores range from 0 to 32 with higher scores indicating worse symptoms. PSI response is defined as total score ≤8 and no item score >1. Symptom-free day is defined as having daily total PSI of 0 on that day.

  8. Number of Symptom-free Days From Randomisation to Week 24

    Time frame: Baseline to Week 24

    The PSI consists of eight psoriasis-specific questions. Trial participants rated the severity of their symptoms in the last 24 hours from 'not at all' to 'very severe,' ranging from 0 to 4. Total scores range from 0 to 32 with higher scores indicating worse symptoms. PSI response is defined as total score ≤8 and no item score >1. Symptom-free day is defined as having daily total PSI of 0 on that day.

  9. Burden of Symptoms

    Time frame: Baseline to Week 24

    Burden of symptoms was assessed as the normalised area under the curve (AUC) of PSI from baseline to the last available assessment. The AUC for the PSI total score was calculated for each participant using the standard trapezoidal rule. The AUC was normalised by dividing it with the time from baseline to the last available assessment of the PSI total score.

    The PSI consists of eight psoriasis-specific questions. Trial participants rated the severity of their symptoms in the last 24 hours from 'not at all' to 'very severe,' ranging from 0 to 4. Total scores range from 0 to 32 with higher scores indicating worse symptoms.

  10. Change From Baseline at Week 24 in Dermatology Life Quality Index (DLQI) Total Score

    Time frame: Baseline to Week 24

    DLQI consists of 10 items addressing the participant's perception of the impact of their skin disease on different aspects of their quality of life over the last week such as dermatology-related symptoms and feelings, daily activities, leisure, work or school, personal relationships, and the treatment. Each item is scored on a 4 point Likert scale (0 = not at all ⁄not relevant; 1 = a little; 2 = a lot; 3 = very much). The total score is the sum of the 10 items (0 to 30); a high score is indicative of a poor QoL.

  11. DLQI Total Score of 0 or 1 at Week 24

    Time frame: Week 24

    DLQI consists of 10 items addressing the participant's perception of the impact of their skin disease on different aspects of their QoL over the last week such as dermatology-related symptoms and feelings, daily activities, leisure, work or school, personal relationships, and the treatment. Each item is scored on a 4 point Likert scale (0 = not at all ⁄not relevant; 1 = a little; 2 = a lot; 3 = very much). The total score is the sum of the 10 items (0 to 30); a high score is indicative of a poor QoL.

Other outcomes

  1. Change From Baseline at Week 24 in NAPSI Total Score

    Time frame: Baseline to Week 24

    The Nail Psoriasis Severity Index (NAPSI) grades nails by first dividing the nail area with imaginary horizontal and vertical lines into 4 quarters. The following 8 clinical features of nail psoriasis are then scored based on the number of quarters in which the feature is present (0 to 4) to arrive at a NAPSI score of 0 to 32 for each nail:

    • Pitting.
    • Leukonychia.
    • Red spots in lunula.
    • Nail plate crumbling.
    • Oil drop (salmon patch) discoloration.
    • Onycholysis.
    • Nail bed hyperkeratosis.
    • Splinter haemorrhages.

    A negative change in NAPSI score means that the NAPSI score was lower at the time of data collection.
