Clinical Trial Summary

Bone disease in multiple myeloma (MM) is routinely assessed by skeletal X-ray (XR) and magnetic resonance of the spine (S-MRI). Diffusion-weighted MRI (DW-MRI) is a functional MRI that detects water diffusion through cells. This prospective phase II study compared whole-body DW-MRI with XR and S-MRI for the assessment of MM bone lesions.

METHODS. Thirty-six consecutive symptomatic patients at diagnosis or at relapse performed XR, S-MRI, whole-body MRI, and whole-body DW-MRI before treatment, after treatment, and 6 months after treatment. A substudy evaluated 12 asymptomatic patients at diagnosis, after 6 and 12 months. Radiology exams were independently read by 3 experienced radiologists, and the techniques were compared by the count of segments with focal lesions (FL) (>=5mm).

PROTOCOL SYNOPSIS -

Study Type Monocentric prospective clinical trial Study Object Comparison of Whole Body Diffusion Weighted Magnetic Resonance Imaging (DW-MRI) with skeletal X-Ray and MRI of the spine for the assessment of bone disease in Multiple Myeloma (MM) Objectives

Primary objective 1) To assess whether DW-MRI can detect a higher number of bone lesions than standard X-Ray and MRI of the spine in Stage I-III symptomatic MM patients Secondary objectives

1. To assess whether the change in the number of lesions detected with DW-MRI at follow up correlate with disease response to therapy

2. To assess whether the change in the number of lesions detected with DW-MRI at follow up correlate with time to re-treatment (TTR)

3. To assess whether DW-MRI detects a higher number of bone lesions than Whole Body Magnetic Resonance Imaging (WB-MRI) Exploratory objective

1) To assess whether DW-MRI detects more bone lesions than standard X-Ray and MRI of the spine in Stage I asymptomatic MM patients at diagnosis not requiring treatment Study population and design The study population consists consecutive Stage I-III (Durie and Salmon) symptomatic Multiple Myeloma at the start of the first-line treatment or at relapse after disease response (CR or PR) lasting at least 6 months.

Study procedures

The patients will perform a DW-MRI, a whole body MRI (WB-MRI), a MRI of the spine and a plain skeletal X-Ray with clinical and laboratory evaluations with the following timing:

1. Patients at first-line treatment for MM:

1. Within 15 days before the start of the treatment

2. Within one month after the end of the first-line treatment

3. 6 months after the end of the first-line treatment

2. Patients at relapse after disease response (CR or PR) lasting at least 6 months

1. At relapse

2. Within 15 days after the end of the treatment of relapse

3. 6 months after the end of the treatment of relapse The DW-MRI, WB-MRI and MRI of the spine will be performed in the same session. Each DW-MRI, WB-MRI, MRI of the spine and skeletal X-Ray will be independently read and interpreted by two radiologists with proven experience in MM. Each radiologist will read and interpret the exams performed; the lecture of each exam will be blinded; the identity of the patient and the result of the lecture by the other radiologist will be blinded. In case the number of lesions detected by the radiologists would not match, the number of lesions will be determined by consensus between the radiologists.

In case of more bone lesions detected by DW-MRI compared to MRI and skeletal X-Ray, a PET scan will be performed.

Sample size The trial is designed to demonstrate a 30% increase in the number of bone lesions detected by DW MRI (experimental method) as compared to standard X-Ray and MRI of the spine (standard method). To detect such an effect size with a one sided Student t test at the 5% significance and 90% power, 27 patients need to be investigated, that we round to 30 to account for a 10% patient drop out. A midcourse sample size reassessment according to the approach proposed by Proschan, Liu & Hunsberger (2003) will use interim data from the first 20 patients to decide to either maintain or increase the original sample size in a range between 30 and 60 patients, depending on whether the estimated effect size is aligned or not with the anticipated value.

Substudy The substudy for the assessment of the exploratory objective will enroll 10 consecutive Stage I (Durie and Salmon) asymptomatic MM patients at diagnosis not requiring treatment. The patients will perform the radiological and laboratory evaluations at diagnosis and at 6 and 12 months after diagnosis.

Study duration The estimated duration of enrolment ranges between 15 and 30 months. The follow up duration is 6 months. The estimated total duration of the study is 3 years. A midcourse assessment of interim data is planned at the end of the first phase of enrolment (20 patients) to determine the sample size of the second phase.
