Imatinib in Systemic Sclerosis
NCT00506831 · View on ClinicalTrials.gov ↗
Study Summary
Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of the skin and internal organs and widespread vasculopathy. Patients with SSc are classified according to the extent of cutaneous sclerosis: patients with limited SSc have skin thickening of the face, neck, and distal extremities, while those with diffuse SSc have involvement of the trunk, abdomen, and proximal extremities as well. The disease course varies depending on the subtype of SSc. However, common features that result in significant morbidity and mortality, in addition to cutaneous fibrosis, include Raynaud's phenomenon and digital ulcerations, interstitial lung disease (ILD), and pulmonary arterial hypertension (PAH). Current therapeutic options for patients with SSc and these clinical manifestations have shown limited efficacy. Imatinib antagonizes specific tyrosine kinases that mediate fibrotic pathways involved in the pathogenesis of SSc, including c-Abl, a downstream mediator of transforming growth factor (TGF)-beta, and platelet derived growth factor (PDGF) receptors. The efficacy of imatinib has also been reported in the treatment of patients with refractory idiopathic PAH through its effects on vascular remodeling. Based on the mechanism of action and preliminary patient data, we hypothesize that imatinib may be effective in the treatment of the fibrotic and vasculopathic features of patients with SSc. This is an open label pilot study to evaluate the safety and efficacy of imatinib in patients with progressive SSc refractory to other treatment(s). Validated measures of skin thickness and disease activity will be determined over 6-months of therapy and compared with baseline measures.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00506831
The ClinicalTrials.gov registry entry for NCT00506831 describes a study currently listed as completed. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 9 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Stanford University, which has 1,643 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Scleroderma, Systemic appearing as the primary indexed condition, and to 1 intervention — of which Imatinib mesylate is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00506831 reports 1 study location spanning 1 distinct geographic area — top geographies include California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
