Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The data described below reflect Gadavist (gadobutrol) exposure in 4549 subjects (4411 adults and 138 children aged 2-17) who received a dose that ranged from < 0.09 to 0.51 mmol/kg body weight; the majority (n=2434) received the recommended dose of 0.1 (±0.01) mmol/kg body weight. Overall, 58.5% of the subjects were men and the ethnic distribution was 64.8% Caucasian, 27.3% Asian, 3% Hispanic, 1.3% Black, and 3.6% patients of other ethnic groups. The average age was 54.2 years (range from 2 to 93 years).

Overall, 4% of subjects reported one or more adverse reactions during a follow-up period that ranged from 24 hours to 7 days after Gadavist (gadobutrol) administration.

Adverse reactions associated with the use of Gadavist (gadobutrol) are usually mild to moderate in severity and transient in nature. Table 1 lists adverse reactions that occurred in ≥ 0.1% subjects who received Gadavist (gadobutrol) .

Postmarketing Experience
