The Vantas hydrogel implant, approved in 2004, releases the drug for twelve months and was labelled for palliative treatment of advanced prostate cancer, suppressing testosterone as effectively as monthly or three-monthly leuprolide with one minor procedure a year. Vantas was discontinued in 2021 after manufacturing problems, while the Supprelin LA implant for children continues. Hot flushes, fatigue and the class effects of androgen deprivation apply.","status":"established","asOf":"2026-09-08","wikipedia":"https://en.wikipedia.org/wiki/Histrelin","links":[{"label":"Drugs@FDA NDA022058","url":"https://www.accessdata.fda.gov/scripts/cder/daf/index.cfm?event=overview.process&ApplNo=022058"},{"label":"Wikipedia","url":"https://en.wikipedia.org/wiki/Histrelin"},{"label":"ChEMBL CHEMBL1201303","url":"https://www.ebi.ac.uk/chembl/explore/compound/CHEMBL1201303"}],"tags":["gap-fill","chembl-universe"],"related":[],"cancers":["prostate"],"sections":[],"technologies":["endocrine-therapy"],"targets":["gnrhr"],"drugs":["leuprolide","goserelin"],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"notes":[],"brand":"Vantas / Supprelin LA","modality":"GnRH agonist, twelve-month subcutaneous implant","mechanism":"A potent GnRH analogue that, given continuously, desensitises the pituitary so luteinising hormone and testosterone fall to castrate levels after an initial surge.","approvals":[],"mechanismSteps":[],"toxicity":[],"access":[],"regulatoryEvents":[]},"route":"/drugs/histrelin/","neighbours":{"cancer":[{"id":"prostate","kind":"cancer","name":"Prostate cancer","route":"/cancers/prostate/"}],"technology":[{"id":"endocrine-therapy","kind":"technology","name":"Endocrine therapy (SERMs, AIs, SERDs)","route":"/technologies/endocrine-therapy/"}],"target":[{"id":"gnrhr","kind":"target","name":"GnRH receptor (GNRHR)","route":"/targets/gnrhr/"}],"drug":[{"id":"goserelin","kind":"drug","name":"Goserelin / leuprolide (ovarian function suppression)","route":"/drugs/goserelin/"},{"id":"leuprolide","kind":"drug","name":"Leuprolide (leuprorelin) and GnRH agonists","route":"/drugs/leuprolide/"}]}}
