An Open-label, Phase 2 Study to Assess the Efficacy and Safety of Nemolizumab in Subjects With Systemic Sclerosis

Compare pre- and post-treatment total mRSS at Week 24. The investigator assessed the degree of skin thickening for each of 17 sites (fingers of both hands, dorsum of both hands, both forearms, both upper arms, face, anterior chest, abdomen, both thighs, both lower legs, and dorsum of both feet) with a 4-point scale from 0 to 3; where 0 = normal skin, 1 = mild thickness, 2 = moderate thickness, and 3 = severe thickness. The total mRSS is the sum of the mRSS of 17 site

Compare pre- and post-treatment total mRSS at Week 52. The investigator assessed the degree of skin thickening for each of 17 sites (fingers of both hands, dorsum of both hands, both forearms, both upper arms, face, anterior chest, abdomen, both thighs, both lower legs, and dorsum of both feet) with a 4-point scale from 0 to 3; where 0 = normal skin, 1 = mild thickness, 2 = moderate thickness, and 3 = severe thickness. The total mRSS is the sum of the mRSS of 17 site

Compare pre- and post-treatment HAQ-DI at Week 24. The HAQ is a questionnaire that patients with chronic diseases answer themselves to assess physical function related to activities of daily living. The questionnaire consists of 20 questions divided into eight categories (dressing and grooming, standing, eating, walking, hygiene, movement, grip strength, and others), which are rated on a four-point scale from 0 to 3. 0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do. The highest value in each category is the index for that category, and the average of these is the HAQ-DI. The higher the HAQ-DI, the greater the degree of functional impairment.

Compare pre- and post-treatment %FVC at Week 24. %FVC is the ratio of the actual measured FVC to the predicted FVC (predicted based on gender, age, and height).

Compare pre- and post-treatment %FVC at Week 52. %FVC is the ratio of the actual measured FVC to the predicted FVC (predicted based on gender, age, and height).

Compare pre- and post-treatment %DLco at Week 24. Pulmonary diffusion capacity refers to the ability to supply gases such as oxygen from alveoli to the alveolar capillaries. DLco is measured for carbon monoxide (CO) and is expressed as the volume (mL) of CO that transfers from alveolar air to the blood per minute per 1mmHg of alveolar partial pressure. %DLco is the ratio of the actual measured DLco to the predicted DLco (predicated based on age, sex, and height)

Compare pre- and post-treatment physician's global assessment at Week 24. Physician's global assessment is a visual analogue scale in which the attending physician assess the condition of systemic sclerosis based on severity, damage, and overall disease status. 0 is the best condition and 10 is the worst condition.

Compare pre- and post-treatment physician's global assessment at Week 52. Physician's global assessment is a visual analogue scale in which the attending physician assess the condition of systemic sclerosis based on severity, damage, and overall disease status. 0 is the best condition and 10 is the worst condition.

Compare pre- and post-treatment patient's global assessment at Week 24. Patient's Global Assessment is a visual analogue scale in which patients rate their systemic sclerosis condition, with 0 being the best and 10 being the worst.

Compare pre- and post-treatment patient's global assessment at Week 52. Patient's Global Assessment is a visual analogue scale in which patients rate their systemic sclerosis condition, with 0 being the best and 10 being the worst.
