Gallium (68Ga) gozetotide, sold under the brand name Illuccix, is a radioactive diagnostic agent used for imaging prostate cancer by positron emission tomography (PET).[1] Specifically it is used in cases that are prostate-specific membrane antigen (PSMA) positive.[1] It is given by injection into a vein.[1]
Common side effects include nausea, diarrhea, and dizziness.[1] Other side effects include radiation exposure.[1] It is made of 68Ga attached to the prostate-specific membrane antigen (PSMA) targeting ligand, Glu-Urea-Lys(Ahx).[6]
Gallium (68Ga) gozetotide was approved for medical use in the United States in 2020.[1] As of 2022 it has been recommended for approval, but has not yet been approved in Europe.[7] In the United Kingdom it costs the NHS about £2,000 per 25 ucg as of 2022.[7]
Medical uses
Gallium (68Ga) gozetotide is a radioactive diagnostic agent indicated for positron emission tomography (PET) of prostate-specific membrane antigen (PSMA)-positive lesions in men with prostate cancer.[4][5]
Ga 68 PSMA-11 injections are used for PET imaging of prostate-specific membrane antigen (PSMA) positive lesions in males with prostate cancer. It can be given for the patients with suspected metastasis, and the candidates with initial definitive therapy.[1]
Dosage
It is given at a dose of 111 MBq to 259 MBq (3 mCi to 7 mCi) about 50 to 100 minutes before imaging.[1]
Mechanism of action
Gallium (68Ga) gozetotide binds with prostate-specific membrane antigen (PSMA).[1] This binds to cells that express PSMA, including malignant prostate cancer cells.[1] The radioactive isotope of gallium, 68Ga is responsible for emitting β+ radiations and X-rays.[1] This helps in recording images by positron emission tomography (PET) and CT scan.[1]
History
Initially gallium (68Ga) chloride solution injections used for radiolabelling,[8] in 2019 European Pharmacopoeia mentions gallium (68Ga) DOTATOC injection for radiolabelling and PET imaging.[9]
Ga 68 PSMA-11 is co-developed by University of California, Los Angeles and University of California, San Francisco, they conducted phase III clinical trial.[10] In December 2020, the drug was first approved by US Food and Drug Administration (FDA) for PET imaging.[11] This is the first drug approved by the US Food and Drug Administration (FDA) as a PET imaging agent.[11]
Society and culture
Legal status
On 13 October 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 Locametz, intended for the diagnosis of prostate cancer.[12] The applicant for this medicinal product is Novartis Europharm Limited.[12]
Names
Gallium (68Ga) gozetotide is the international nonproprietary name (INN).[13]
