Lutetium (177Lu) chloride is a radioactive compound used for the radiolabeling of pharmaceutical molecules, aimed either as an anti-cancer therapy or for scintigraphy (medical imaging).[1][2] It is an isotopomer of lutetium(III) chloride containing the radioactive isotope 177Lu, which undergoes beta decay with a half-life of 6.65 days.
Medical uses[]
Lutetium (177Lu) chloride is a radiopharmaceutical precursor and is not intended for direct use in patients.[1] It is used for the radiolabeling of carrier molecules specifically developed for reaching certain target tissues or organs in the body. The molecules labeled in this way are used as cancer therapeutics or for scintigraphy, a form of medical imaging.[1] 177Lu has been used with both small molecule therapeutic agents (such as 177Lu-DOTATATE) and antibodies for targeted cancer therapy[3][4]
Contraindications[]
Medicines radiolabeled with lutetium (177Lu) chloride must not be used in women unless pregnancy has been ruled out.[1]
Adverse effects[]
The most common side effects are anaemia (low red blood cell counts), thrombocytopenia (low blood platelet counts), leucopenia (low white blood cell counts), lymphopenia (low levels of lymphocytes, a particular type of white blood cell), nausea (feeling sick), vomiting and mild and temporary hair loss.[1]
Drug approval[]
Lutetium (177Lu) chloride (Lumark) was approved for use in the European Union in June 2015.[1] Lutetium (177Lu) chloride (EndolucinBeta) was approved for use in the European Union in July 2016.[2]
