Adenocarcinoma
Conditions
Brief summary
The primary objectives of this study were to assess the safety and tolerability of intravenously (i.v.) administered 186Rhenium (186Re)-labelled bivatuzumab and to investigate the biodistribution and pharmacokinetics of 186Re-labelled bivatuzumab in patients with adenocarcinoma of the breast
