title: [A phase 2 clinical study of 99mTc-MAG3 injectable a dynamic renal imaging agent--evaluation of its safety, effectiveness and optimal dose].
abstract: A phase 2 clinical study of 99mTc-mercapto acetyl glycylglycylglycine (99mTc-MAG3) injectable, a new dynamic renal imaging agent, was performed in 110 patients with renal and/or urinary disorders to evaluate the safety, efficacy and optimal dose of this agent. Neither adverse reactions nor abnormal laboratory findings due to intravenous administration of 99mTc-MAG3 were observed. The investigators evaluated the clinical efficacy of 99mTc-MAG3 was to be effective in 96 of 97 cases. Among the doses of 92.5 MBq, 185 MBq, 370 MBq and 555 MBq, the dose of 92.5 MBq was not large enough to provide adequate-quality blood flow images or reliable information for evaluation of the renal blood flow. It was concluded that the optimal dose range of 99mTc-MAG3 was 185-555 MBq with 370 MBq as the standard dose. Also, we surmise that 555 MBq is especially recommendable when detailed blood flow information is required. These results indicate that 99mTc-MAG3 injectable is useful for the diagnosis of renal and urinary disorders.
