Active clinical trials for "Giant Cell Tumors"

This study will examine the response rate and the 6-month progression-free survival rates of subjects with advanced sarcoma treated with dasatinib.

This 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.

The 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

Study 20140114 will continue to follow subjects with GCTB who were treated in Study 20062004 and remained on the study at the completion of Study 20062004 for an additional 5 years on long-term safety follow up.

This is a retrospective observational real-world study, which evaluates the efficacy and safety of denosumab and non-denosumab therapies in the treatment of Chinese populations of surgically unsalvageable or severe post-surgery morbidity associated giant cell tumor of bone (GCTB), collectively referred to as unresectable GCTB, during 2013-2021 in three medical centers, serving as the external control for a single arm phase Ib/II trial on JMT103 treatment of GCTB. 301 patients were enrolled and divided into 2 groups according to their actual previous exposures. Group 1 (n=135) was denosumab group. Group 2 (n=166) included two types of exposures other than denosumab: other anti-GCTB drug therapies, or no therapy on GCTB patients. The dosage, route, frequency and other administration methods was collected according to the actual previous treatment records. The primary outcome measure was the tumor response rate [radiographic tumor response (CR/PR evaluated by ICDs or EORTC criteria) within 12 weeks, or at least 90% reduction of osteoclast like giant cells compared with baseline]. The key secondary endpoint was the tumor response rate [radiographic tumor response (CR/PR evaluated by ICDS or EORTC criteria), or at least 90% reduction of osteoclast like giant cells compared with baseline]. Other secondary Outcome Measures include: proportion of patients whose tumors was surgically resectable; median duration of tumor response (DOR), disease control rate (DCR), and time to disease progression (TTP); and types and proportion of key adverse reactions.

Giant cell tumor of bone (GCTb) is a primary, osteolytic, benign tumor of the bone. Surgery is the commonly used treatment. Discovery of RANKL and its human monoclonal antibody, denosumab, led to use of denosumab for treatment of GCT. The aim of this study was to evaluate clinical and pathological results of treatment of relapsed or refractoriness GCT with denosumab and to assess adverse effect profile and recurrence rate.

TGCT is a rare disease that is difficult to manage, surgical resection is the primary treatment currently available. To date no disease registry exists and there is little data available detailing the management of patients with diffuse TGCT, the burden of diffuse TGCT for patients (including pain, joint stiffness, swelling, reduced mobility and quality of life) or the economic impact of diffuse TGCT. This study aims to collect data by an observational disease registry involving no intervention to the patient or changes to investigators treatment decisions.

single institution cases series review of histological and clinical data of young patient with Giant Cell Tumors

The purpose of this project is to present the outcomes of patients with giant cell tumor of bone (GCTB) who were treated with surgery and/or medical treatment in a single institution.

Exploit CT (plain scan), enhanced CT and fMRI based radiomic biomarkers, explore their correlation with the prognostic molecular markers of spinal GCTB(p53/vegf/rank/rankl…), and help accurate diagnosis of GCTB. Exploring a new method of preoperative risk stratification for spinal GCTB, and establishing radiomic model combined with clinical features. Exploring the GCTB biological behavior prediction model and the prognosis prediction of GCTB.
