Clinical Trial: Imatinib Mesylate (Gleevec) in the Treatment of Systemic Sclerosis
Study Status: Completed
Recruit Status: Unknown status
Study Type: Interventional
Official Title: Phase IIA Study of the Safety and Tolerability of the Use of Imatinib Mesylate (Gleevec) in the Treatment of Systemic Sclerosis
Brief Summary:
The purpose of this study is to assess the safety and tolerability of imatinib mesylate (Gleevec) in patients with systemic sclerosis (scleroderma). Gleevec is a medication already FDA approved for the treatment of chronic myelogenous leukemia (CML), gastrointestinal stromal tumors (GIST), dermatofibrosarcoma protuberans tumors, Philadelphia chromosome-positive acute lymphoblastic leukemia, hypereosinophilic syndrome, and aggressive systemic mastocytosis. In-vitro studies have suggested that imatinib may inhibit collagen production by scleroderma fibroblasts, and in mouse models of fibrosis imatinib has been shown to decrease skin thickness.
This is a Phase IIa, single center, prospective open label clinical trial of Gleevec in patients with systemic sclerosis. All patients will be treated with active drug for 12 months. The primary objective of this study will be to determine the safety and tolerability of Gleevec in patients with systemic sclerosis, but important secondary outcomes of relevance will be improvement in disease status as defined by skin scores and indices of pulmonary function.
Patients who complete the initial phase (described above) of the study will be eligible to participate in an extension phase. The purpose of the extension phase of the study is to give patients who participated in the phase IIa clinical trial of Gleevec at the Hospital for Special Surgery the opportunity to continue Gleevec treatment if both the treating physicians and the patient are in agreement that Gleevec had acceptable safety and tolerability, as well as possible efficacy during the initial year of therapy.
Detailed Summary:
Further description of extension phase:
Patients will first be evaluated for inclusion in the extension phase of the study at either the follow-up visit following three month withdrawal from Gleevec treatment or at the visit after the follow-up visit. Patients can undergo evaluation for inclusion in the extension phase up to six months following their completion of the initial one year trial. All patients evaluated for inclusion in the extension phase will sign a new informed consent form detailing the purpose and procedures associated with the extension phase at the initial visit. After the initial visit, patients who meet inclusion criteria will be required to undergo evaluation every three months for the 27 months following initiation of treatment, or more frequently if deemed clinically necessary. Treatment will consist of Gleevec, at doses ranging from 100 to 400 mg daily (100 mg pills will be distributed for oral administration). At each study visit, a history and physical exam will be performed and urine and blood tests will be conducted for disease activity and organ function. Additional blood for research may also be collected at study visits. The Modified Rodnan Skin Score will be measured to assess the degree of skin involvement associated with the patient's disease. Patients will also continue to complete questionnaires about their ability to function and quality of life.
Patients will be financially responsible for all professional and clinical services, as well as all laboratory and diagnostic tests, associated with the extension phase of the study. All co-pays, deductibles and co-insurances will be paid by the participants. Any additional costs for parking and travel the patients incur as a result of participating in the extension phase will not be reimbursed by the study. Novartis Pharmaceuticals will donat
