EndolucinBeta

(177Lu)lutetium(3+) trichloride

Diagnostic aid, Radioactive agent

Lutetium 177 is an isotope of a rare-earth lanthanide metal lutetium. Radioactive decay of Lu 177 produces electrons with low energies making the isotope suitable for treatment of metastatic disease. A complex of Lu177 and somatostatin analog DOTA-TATE was approved by the FDA for the treatment of somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors, including foregut, midgut, and hindgut neuroendocrine tumors in adults. It is marketed under a tradename Lutathera. Lutetium in the complex with other carriers – phosphonates and monoclonal antibodies – was investigated in clinical trials as radiotherapy to prostate, ovarian, renal and other types of cancer.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).[5][6] 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.[5] 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.[5] 177Lu has been used with both small molecule therapeutic agents (such as 177Lu-DOTATATE) and antibodies for targeted cancer therapy[8][9]

Contraindications

Medicines radiolabeled with lutetium (177Lu) chloride must not be used in women unless pregnancy has been ruled out.[5]

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.[5]

Society and culture

Legal status

Lutetium (177Lu) chloride (Lumark) was approved for use in the European Union in June 2015.[5] Lutetium (177Lu) chloride (EndolucinBeta) was approved for use in the European Union in July 2016.[6]

On 21 July 2022, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Illuzyce, a radiopharmaceutical precursor.[10] Illuzyce is not intended for direct use in patients and must be used only for the radiolabelling of carrier medicines that have been specifically developed and authorized for radiolabelling with lutetium (177Lu) chloride.[10] The applicant for this medicinal product is Billev Pharma ApS.[10] Illuzyce was approved for medical use in the European Union in September 2022.[7]
