About

The FULIMA study is a two-center study at Odense University Hospital and Vejle Hospital, Denmark. The primary objective is to identify the optimal imaging technique for studies in multiple myeloma with focus on PET/CT and MRI.

By combining early (1 hour) and late (3 hours) 18F-2-fluoro-2-deoxy-D- fluorodeoxyglucose(18F-FDG)-PET/CT scans the investigators expect to see increased uptake of radioactive tracer and thus an improved ability to identify malignant tissue. A second tracer 18F-natrium-fluoride is used to explore early signs of bone remodeling. By using new software (ROVER) for interpreting PET data the investigators expect to obtain a quantitative measurement of total disease burden with less risk of misinterpretation of data.

Diffusion weighted MRI (DWI) is a new MRI technique which, like PET/CT, makes it possible quantitatively to calculate the overall disease activity and to give an early evaluation of response to chemotherapy. The study examines DWI for development and standardization.

To validate imaging findings and to explore the pathogenetic heterogeneity of multiple myeloma, the investigators perform CT guided biopsies from PET/ DWI positive sites. Pathoanatomical and immunohistochemical findings and gene expression data from positive sites are compared to random bone marrow. The question is whether disease heterogeneity may explain the lack of FDG uptake in bone marrow in some patients? To the extent that the FULIMA study produces useful data, the defined and standardized imaging techniques will form the basis of a larger prospective study at national level in Denmark.

4. Subject is willing and able to comply with the protocol as judged by the investigator.

Exclusion criteria

1. Formerly treated multiple myeloma.
2. Known inflammatory disease, recent biological therapies or chemotherapy for non-malignant disease (less than 3 months prior to screening), clinically relevant active infection.
3. Concurrent or recent radiotherapy or surgery less than two weeks prior to screening
4. Glucocorticoid treatment exceeding 10 mg Prednisolone daily, less than two weeks prior to screening.
5. Any condition, including laboratory abnormalities, that in the opinion of the investigator places the subject at an unacceptable risk if s/he were to participate in the study, e.g. high levels of liver-enzymes and creatinine.
6. Female subject is pregnant or breast feeding.
