Active clinical trials for "Neoplasms, Bone Tissue"

The goal of this clinical trial was to compare participants with first relapse or refractory Ewing's sarcoma when treated with investigational product (Vigil) in addition to the standard treatment of irinotecan and temozolomide compared to the standard treatment of irinotecan and temozolomide alone. The main question it aimed to answer is "Will participants who receive Vigil in addition to irinotecan and temozolomide have a prolonged time to progression and improved quality of life compared to the participants who receive irinotecan and temozolomide alone?".

Bone metastases appear in many cancers. They are associated with severe pain that is refractory to standard treatment. Improving the quality of life and better pain relief is therefore an essential goal of the treatment of metastatic disease. The most common site of long bone metastases is the superior femoral epiphysis. The usual management of patients with bone metastases in the superior femoral epiphysis is based on gamma implant osteosynthesis when there is a known risk of fracture (Mirels score> 8). Nonetheless this surgery is only accessible to a few patients because of the associated morbidities. Percutaneous cementoplasty has been developed to treat patients who are not eligible for conventional surgery. It consists in a filling of the bone cavity created by metastasis using an acrylic resin. However, these approaches do not completely prevent the risk of upper femoral epiphyseal fracture due to the low mechanical resistance of the resin to shear movements. The Y-STRUT® implantable medical device was developed to overcome this risk of superior femoral epiphyseal fracture by the biomechanical strengthening of the proximal femur in addition to cementoplasty. It has been successfully tested in more than 70 patients with cancer but access to reimbursement and the APHP market have been postponed due to lack of sufficient clinical evidence. The investigators propose this prospective phase 2a study in order to provide evidence of the performance of the Y-STRUT® implant.
