Phase 3 Study of Pexidartinib for Pigmented Villonodular Synovitis (PVNS) or Giant Cell Tumor of...
Pigmented Villonodular SynovitisGiant Cell Tumors of the Tendon Sheath1 moreThis is a Phase 3 clinical study, which aims to evaluate the effectiveness of an investigational drug called pexidartinib for the treatment of certain tumors for which surgical removal could cause more harm than good. The main purpose of this study is to gather information about the investigational drug pexidartinib, which may help to treat tumors of pigmented villonodular synovitis (PVNS) or giant cell tumor of the tendon sheath (GCT-TS). The study consists of two parts with a follow-up period. In Part 1, eligible study participants will be assigned to receive either pexidartinib or matching placebo for 24 weeks. A number of assessments will be carried out during the course of the study, including physical examinations, blood tests, imaging studies, electrocardiograms, and questionnaires. MRI scans will be used to evaluate the response of the tumors to the treatment. Some subjects, assigned to placebo in Part 1 transitioned to pexidartinib for Part 2. Then a protocol amendment was written to allow only pexidartinib patients to continue into Part 2. Part 2 is a long-term treatment phase in which all participants receive open-label pexidartinib. There was also a follow-up period added to Part 2.
Study of Nilotinib Efficacy in Pigmented Villo-Nodular Synovitis/ Tenosynovial Giant Cell Tumour...
Pigmented Villonodular SynovitisThe purpose of this study is to explore the efficacy of nilotinib as a treatment of patients with progressive or relapsing pigmented villo-nodular synovitis / tenosynovial giant cell tumour (PVNS/TGCT) who cannot be treated by surgery. The primary objective of the study will be to determine the efficacy of 12 weeks (3 months) of nilotinib treatment as measured by the non progression rate (Complete response + Partial Response + Stable disease according to Response Evaluation Criteria In Solid Tumours - RECIST version 1.1) in patients with progressive or relapsing PVNS/TGCT who cannot be treated by surgery. this study is an international, multicentre, non-randomized, open-label phase II clinical trial with a Bayesian design. A maximum sample size of 50 patients will be included in the study
Clinical Study of Magnetic Resonance Imaging and Deep Learning of Joint Synovial Disease
Synovial DiseasesPigmented Villonodular Synovitis2 moreThrough the high-throughput feature extraction of magnetic resonance images, the deep learning prediction model of joint synovial lesions is constructed used for the diagnosis, differential diagnosis and curative effect monitoring of joint synovial lesions.
Screening of Specific Genes for Pigmented Villous Nodular Synovitis
Pigmented Villonodular SynovitisThis study retrospectively analyzed the history of present illness of PVNS patients in our hospital. The enrolled patients were followed up by telephone to follow up their postoperative recovery and living conditions. Take the patient's pathological specimens for immunohistochemical testing, evaluate the relationship between the expression of different molecular targets, clinical manifestations and patient prognosis, and explore new molecular targets related to disease diagnosis and treatment.
Evaluation of the Effectiveness of Surgical Treatment of Villo-nodular Synovitis of the Hip in Children...
SynovitisVillo-nodular synovitis can affect the joints, bursae or tendon sheaths. This condition is rare, with 1.8 cases per million inhabitants. The hip is affected in 3.6 to 18.1% of cases. The age of predilection is between 30 and 50 years old and this condition is rarely described in children. Two articles report a case of villous-nodular synovitis of the child's hip. Surgical treatment by resection seems to be consensus but various adjuvant treatments are also proposed. A case of villous-nodular synovitis of the hip in children was treated without surgical intervention. The main objective of this study was to evaluate the efficacy of surgical treatment of villous nodular synovitis of the hip in children.
