This study with standardized reading MRIs, will provide for the first time objective and quantified data on organomegaly (liver and spleen volumes) as well as bone alteration (Bone Marrow Burden11) of French patients treated with VPRIV®. These data will help to better assess the impact of this treatment on these parameters.
The result of this study will also answer in part to the request of the French Transparency Commission (CT: Commission de Transparence) of the French National Health Authority to provide them with data of French patients treated with VPRIV®.
All data entered will be used for analysis purposes and results will be submitted to inform regulatory agencies. Patient care and management is freely determined by the participating physician, in the framework of an observational study reflecting the daily medical practice. The clinical data, the results of routine clinical and laboratory testing that are part of standard medical care for patients with Gaucher disease will be collected from the medical record of the patient :
The MRI images collected during the study:
The MRIs performed in the patient's usual medical follow-up for its Gaucher disease (abdominal MRI (liver and spleen) and bone MRI (back injury pelvis, lower limbs) and / or whole-body MRI) will be collected. Among the MRIs available in the patient's medical records, MRIs will be collected as following:
Second reading of the MRI
The collected MRIs will be subject to a second reading, which will be conducted centrally by a medical image processing center (BioClinica).
This second reading of MRIs will particularly provide quantitative data not available initially in the patient records, such as Bone Marrow Burden (BMB) score at the lumbar spine and femur, and liver and spleen volumes.
In case the second reading provides additional data to the first reading, as any new comments or discordant diagnosis, the investigating doctor will integrate these data as soon as he has knowledge of them in the medical care of the patient.
MRI collection and transmission
Except the data from the second reading of MRIs by BioClinica, all data defined above, will be collected in the case report of the study, from the patient's medical record.
For the second centralized reading of the MRIs, the MRIs will be transmitted as follows: the investigation center will make a copy on Compact Disc - Read Only Memory (CD-ROM) of each MRI collected for the study needs, and will replace the identity the patient by an identification number whose correspondence with the patient's identity is only known by the investigation center. This patient identification number will be predefined and attributed to the patient's MRI when the patient is included in the study.
Copies of MRIs and coded will be sent securely at BioClinica center for analysis. In case of connection failure from the participating centers, MRI scans will be sent by post.
Data from this second reading by BioClinica will be retrieved for analysis. The results of the second reading by BioClinica will be forwarded to investigation center, which will include them in the patient's record.
