Effects of FT011 in Systemic Sclerosis
Study Details
Study Description
Brief Summary
FT011 is an anti-fibrotic drug that is being tested as a treatment for scleroderma. This study is being conducted to see what the body does to the drug (pharmacokinetics), and what the drug does to the body (pharmacodynamics).

Outcome Measures
Primary Outcome Measures
- FT011 levels in plasma [1, 2, 3, 4, 5 ,6 ,7, and 8 hours post dose on Day one and at Week 12]
Measurement of maximum concentration (cmax) of FT011
- FT011 levels in plasma [1, 2, 3, 4,5 ,6 ,7, and 8 hours post dose on Day one and at Week 12]
Measurement of time to cmax (tmax)
- FT011 levels in plasma [1, 2, 3, 4, 5 ,6 ,7, and 8 hours post dose on Day one and at Week 12]
Measurement of area under the concentration time curve (AUC)
Secondary Outcome Measures
- Number of Participants with Treatment-Emergent Adverse Events (TEAEs) from Baseline to End of Study [Baseline to Week 16]
TEAEs per arm during study treatment and follow up periods
- mRSS change from Baseline [Week 4, Week 8, Week 12, and Week 16]
The mRSS is a validated physical evaluation of patient's skin thickness rated by clinical palpation using a 0-3 scale (0 = normal skin; 1 = mild thickness; 2 = moderate thickness; 3 = severe thickness with inability to pinch the skin into a fold) for each of 17 surface anatomic areas of the body: face, anterior chest, abdomen, and, with right and left sides of the body separately evaluated, the fingers, forearms, upper arms, thighs, lower legs, dorsum of hands and feet. Individual values are summed and defined as the total skin score. Total score is 0 to 51 with higher scores indicating worse symptomology
- %FVC change from Baseline [Week 4, Week 8, Week 12]
Percent predicted FVC is calculated using equations incorporating age, gender, and race. It is calculated as (FVC Observed / FVC predicted) x 100, where FVC predicted is calculated relative to a reference population
- Physician Global Assessment change from Baseline [Week 4, Week 8, Week 12]
The physician's assessment of the patient's SSc status will be scored on a 100-mm horizontal VAS, ranging from 0 on the extreme left end of the scale indicating "no disease activity" (symptom free), and 100 on the extreme right end indicating "worst imaginable disease activity".
- Patient Global Assessment change from Baseline [Week 4, Week 8, Week 12]
The Patient's Global Assessment represents the patient's overall assessment of current SSc status on a 100-mm horizontal VAS, ranging from 0 on the extreme left end of the scale indicating "no disease activity" (symptom free), and 100 on the extreme right end indicating "worst imaginable disease activity".
- Scleroderma HAQ-DI change from Baseline [Week 4, Week 8, Week 12]
The HAQ-DI consists of 20 questions referring to eight component sets consisting of dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities. Each item is scored from 0 to 3. The eight scores of the eight sections are summed and divided by 8. The total score indicates the patient's self-assessed level of disability - higher scores indicate worse symptomology. A negative change from baseline indicates improvement. The Scleroderma HAQ (SHAQ) includes an additional five scleroderma-specific visual analogue scales (VAS), addressing overall disease activity, Raynaud's phenomenon, finger ulcers, breathing, and intestinal problems. A composite VAS score is not created nor are the individual VAS scores incorporated into the HAQ DI score.
- Combined Response Index in Diffuse Cutaneous Systemic Sclerosis (CRISS) at Week 12 [Week 12]
CRISS components include modified Rodnan skin score (mRSS), forced vital capacity percent predicted (%FVC), Physician Global Assessment, Patient Global Assessment, and Health Assessment Questionnaire Disability-Index (HAQ-DI). The exponential algorithm determines the predicted probability of improvement from baseline, incorporating change in these 5 components. The outcome is a continuous variable between 0.0 and 1.0 (0 - 100%). A higher score indicates greater improvement
- Scleroderma Clinical Trial Consortium Damage Index (SCTC-DI) change from Baseline [Week 4, Week 8, Week 12]
The SCTC-DI is a 23-item composite damage index to quantify organ damage in systemic sclerosis
- 5-D Itch Scale change from Baseline [Week 4, Week 8, Week 12]
The 5-D itch scale is a validated brief multidimensional questionnaire designed to be useful as an outcome measure in clinical trials. The five dimensions are degree, duration, direction, disability, and distribution.

-

-
The use of the following drugs within the specified periods:
-
