EncompaSSc: Evaluierung von MTX-474 bei Teilnehmern mit diffuser kutaner systemischer Sklerose (dcSSc)

1. Oktober 2026 aktualisiert von: Mediar Therapeutics

Eine randomisierte Phase-2-Doppelblindstudie mit Placebokontrolle zur Bewertung der Sicherheit und Wirksamkeit von MTX-474 bei der Behandlung von Teilnehmern mit diffuser kutaner systemischer Sklerose (dcSSc)

Detaillierte Beschreibung

Participants with dcSSc who meet the study's inclusion and exclusion criteria will be randomly assigned in a 3:2 ratio to receive MTX-474 or a matching placebo by intravenous (IV) infusion. Concomitant use of one of the approved dcSSc therapies (immunosuppressive therapy, systemic glucocorticoids or other antifibrotic agents) is permitted under certain criteria. Participants randomized to the MTX-474 arm of the study will receive an IV infusion every 4 weeks, beginning at Day 0 and ending at Week 20. The End of Treatment Visit will occur at Week 24, and a Safety Follow-Up Visit will occur at Week 28, 8 weeks after the final infusion. mRSS assessments will occur at Screening, Baseline, and at all subsequent treatment visits up to and including Week 24. Spirometry will be performed at screening and Weeks 12. HRCT will be performed at screening and week 24. DLCO will be performed at Screening. Skin biopsies will be performed at Baseline and Week 12. Participants will have blood drawn for safety assessment and to assess Ephrin receptor levels at Screening, Baseline and every 4 weeks until Week 28. Blood will be drawn for serum PK analyses relative to the first and last doses of MTX-474.

Proportion of participants achieving a response on the revised ACR Composite Response Index in Systemic Sclerosis (rACR-CRISS), stratified by baseline EphrinB2 levels.

Unit of Measure: Participants (%)

Up to 24 weeks
To assess the presence, titer and impact of antidrug antibodies (ADA) against MTX-474
Zeitfenster: Baseline to week 28

Samples will be collected from baseline until Week 28 to assess the rate at which antibodies develop to the study drug Unit of Measure: Titer units

Baseline to week 28
Change from baseline in expression of total and phosphorylated EphB2, EphB3, and EphB4 receptors in skin
Zeitfenster: Baseline to Week 12

Mean change from baseline to Week 12 in total and phosphorylated EphB2, EphB3, and EphB4 receptor expression in skin biopsy samples.

Unit of Measure: Relative expression units (fold change from baseline)

Baseline to Week 12
Change from baseline in transcriptomic profile
Zeitfenster: Baseline to Week 12

Change from baseline to Week 12 in global transcriptomic profile via bulk RNA sequencing analysis of skin biopsies in each arm.

Unit of Measure: Differential gene expression (log₂ fold change)

Baseline to Week 12
Change from baseline in serum biomarkers of organ involvement
Zeitfenster: Baseline to weeks 12 and 24

Change from baseline to Weeks 12 and 24 in serum levels biomarkers, including but not limited to, ProC3 and IL-6 associated with organ involvement Unit of Measure: ng/mL (or unit per biomarker)

Baseline to weeks 12 and 24
Change from baseline in fatigue symptoms (FACIT-Fatigue score)
Zeitfenster: Baseline to week 24

Mean change from baseline to Week 24 in fatigue symptoms as measured by the Functional Assessment of Chronic Illness Therapy-Fatigue Scale.

Unit of Measure: Units on FACIT-Fatigue scale (range 0-52; higher score = less fatigue)

Baseline to week 24
Change from baseline in gastrointestinal (GI) symptoms (UCLA SCTC GIT 2.0 score)
Zeitfenster: Baseline to week 24

Mean change from baseline to Week 24 in GI symptom burden assessed by the UCLA SCTC GIT 2.0 questionnaire.

Unit of Measure: Units on UCLA SCTC GIT 2.0 total score (range 0-3; higher score = worse symptoms)

Baseline to week 24
Change from baseline in anxiety and depression symptoms (HADS)
Zeitfenster: Baseline to week 24

Mean change from baseline to Week 24 in symptoms of anxiety and depression measured by the HADS instrument.

Unit of Measure: Units on Hospital Anxiety and Depression Scale (HADS total and subscale scores; range 0-21 per subscale; higher score = worse symptoms)

Baseline to week 24
Change from baseline in HAQ-DI
Zeitfenster: Baseline to week 24

Mean change from Baseline in functional disability as assessed by HAQ-DI. Unit of measure: Score (0-3 scale)

Baseline to week 24
