Its molecular target is not stated in the ClinicalTrials.gov intervention record, and OnCo has not confirmed one from the sponsor's pipeline page. The sponsor states: Combines RTGel technology with medac's mitomycin formulation for kidney-sparing treatment of low-grade upper tract urothelial cancer; currently in a Phase 3 study. ClinicalTrials.gov describes the intervention as: UGN-104 consists of mitomycin and sterile hydrogel (a proprietary thermally responsive gel) that is used to reconstitute mitomycin before instillation. The reverse thermal properties of UGN-104 allow for local administration of mitomycin as. It is the investigational product in 1 recruiting or active industry-led phase 2 and phase 3 interventional cancer trial, including the phase 3 study NCT06774131 (A Phase 3 Single-arm Study of UGN-104 for the Treatment of Low-grade Upper Tract Urothelial Cancer), in bladder & urothelial cancer. The largest, NCT06774131, plans to enrol 70 participants with primary completion expected 2027-03. Status reflects the highest phase registered on ClinicalTrials.gov; no efficacy results are recorded here.","status":"phase-3","asOf":"2026-09-11","links":[{"label":"ClinicalTrials.gov: trials of UGN-104","url":"https://clinicaltrials.gov/search?intr=UGN-104"},{"label":"Sponsor page","url":"https://www.urogen.com/pipeline"}],"tags":["pipeline","ctgov-ingest"],"related":[],"cancers":["urothelial"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":["urogen-pharma"],"institutions":[],"pathways":[],"terms":[],"trials":["nct06774131"],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"provenance":{"editedBy":"OnCo ingestion (ClinicalTrials.gov v2 + sponsor pipeline pages)","editedOn":"2026-09-11"},"modality":"chemotherapy (mitomycin) delivered via hydrogel","mechanism":"Combines RTGel technology with medac's mitomycin formulation for kidney-sparing treatment of low-grade upper tract urothelial cancer; currently in a Phase 3 study.","approvals":[],"mechanismSteps":[],"toxicity":[],"access":[],"regulatoryEvents":[]},"route":"/drugs/ugn-104/","neighbours":{"cancer":[{"id":"urothelial","kind":"cancer","name":"Bladder & urothelial cancer","route":"/cancers/urothelial/"}],"company":[{"id":"urogen-pharma","kind":"company","name":"UroGen Pharma","route":"/companies/urogen-pharma/"}],"trial":[{"id":"nct06774131","kind":"trial","name":"A Phase 3 Single-arm Study of UGN-104 for the Treatment of Low-grade Upper Tract Urothelial Cancer","route":"/trials/nct06774131/"}]}}
