Breast Cancer

Efficacy and safety of gadobutrol 1.0 molar (Gadovist) for breast magnetic resonance imaging (MRI)

Trial purpose

The purpose of this study is to look at the efficacy (how does it work) and safety of gadobutrol when used for obtaining MR images of both breasts.Women with a recent diagnosis of breast cancer by mammogram (X-ray examination of the breasts) may benefit from MRI of the breasts as MRI may detect additional breast cancers

Primary Outcome

  • Sensitivity for detection of full extent of malignant breast disease using CMRM vs UMRM per reader
    For a single participant the sensitivity was defined as the proportion of malignant breast regions that were recognized by the reader using the respective imaging modality as malignant. Subsequently the point estimates will be calculated based on the mean of the sensitivities across all participants. For ease of expression, the following abbreviations will be used: Magnetic Resonance Mammography (MRM), Unenhanced MRM (UMRM), combined unenhanced and contrast (gadobutrol)-enhanced MRM (CMRM), X-ray mammography (XRM)

  • Breast level specificity of CMRM for non-malignant breasts by reader
    A non-malignant breast was defined as false positive (FP), when the reader assessed at least one breast region as malignant. When all breast regions were assessed as non-malignant, the breast was defined as true negative (TN). Breast level specificity was first defined in participant as number of TN-breasts in participant divided by number of non-malignant breasts in participant. Subsequently the point estimates were calculated based on the mean of the specificities across all participants who contributed with at least one non-malignant breast.

Secondary Outcome

  • Breast level specificity of CMRM based on malignant breasts
    A malignant breast was defined as FP, when the reader using the respective imaging modality assessed more breast regions as malignant as were present according to SoT. Otherwise the breast was assessed as TN. Specificity was then defined as TN/(TN+FP).

  • Percentage difference of participants whose index cancers were detected using CMRM vs UMRM, CMRM vs XRM, and CMRM vs CMRM+XRM
    Index cancer was defined as the cancer confirmed by histology prior to inclusion which made the participants eligible for the study.

  • Percentage difference of participants whose additional index cancers were detected using CMRM vs UMRM, CMRM vs XRM, and CMRM vs CMRM+XRM
    Additional cancer was defined as cancer which was present according to SoT, but which was not defined as index cancer, i.e. was not known when the participant was enrolled into the study

  • Difference of confidence in diagnosis for breast region diagnosis using CMRM vs UMRM, CMRM+XRM vs UMRM+XRM and CMRM+XRM vs XRM by reader, participant level
    The investigator and the blinded readers each recorded his/her confidence in diagnosis for each breast region based on a 4-point scale (1 = not confident, 2 = somewhat confident, 3 = confident, and 4 = very confident). For each participant, the mean of the confidence responses for the diagnosed breast regions was calculated, and rounded to the nearest 0.5.

Trial design

An open label, multi-center, phase 3 study with corresponding blinded image reading to determine the efficacy and safety of a single intravenous injection of 0.1 mmol/kg body weight of gadobutrol 1.0 molar (Gadovist®) in patients with newly diagnosed breast cancer referred for contrast-enhanced breast MRI
