View clinical trials related to Aggressive Fibromatosis.
Filter by:Background: - Desmoid tumors (also known as aggressive fibromatosis), are rare, locally invasive, slow-growing soft-tissue tumors. The disease can be either asymptomatic or be associated with severe loss of organ function and significant morbidity. - Treatment with the selective small-molecule Gamma-secretase inhibitor PF-03084014 caused significant tumor shrinkage in patients with unresectable desmoid tumors in an early phase clinical trial. - The Notch pathway is a key regulator of cell differentiation, proliferation and apoptosis; aberrant signaling via the Notch pathway is associated with carcinogenesis. Objectives: - Primary: Determine the response rate (Complete Response (CR)+Partial Response (PR)) of PF-03084014 in patients with desmoid tumors/aggressive fibromatosis - Secondary: Assess symptom measures at baseline and on study; perform genotyping for germline and somatic mutations in adenomatous polyposis coli gene (APC) and catenin-beta 1 (CTNNB1) genes; correlate clinical response to therapy with genotyping data; and assess modulation of the Notch pathway by evaluating notch response genes in tumor biopsies at baseline and after drug administration Eligibility: - Age greater than or equal to18; histologically confirmed desmoid tumor not amenable to curative resection or definitive radiation therapy that has progressed after receiving at least one line of standard treatment; adequate organ function - Willingness to provide blood samples and 10 unstained slides or a tumor block for genetic research studies Study Design: - This is an open-label Phase II trial of PF-03084014; study drug will be administered orally at 150 mg twice a day in 21-day cycles - Optional tumor biopsies for research purposes will be performed at baseline prior to study treatment and at the beginning of cycle 7 (+/- one cycle) - Restaging scans (magnetic resonance imaging (MRI) with diffusion weighting) will be performed at baseline, at the end of cycles 1 and 6, and then every 6 cycles - Health-related quality of life (HRQOL)/symptom questionnaires will be administered at baseline and at each Clinical Center visit
The objective of the present study is to evaluate the activity and safety of imatinib in patients with aggressive fibromatosis who, after receiving the standard therapy, show an inoperable recurrent tumor or disease not readily controllable by surgery or radiotherapy.
