Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of the study is to learn about the safety of Sacituzumab Tirumotecan and if people can tolerate it when given in the bladder and find the highest dose that people can take without having certain problems. Researchers will then choose a dose level of Sacituzumab Tirumotecan to use in future studies to learn how well the drug works.

Sacituzumab tirumotecan

Participants receive intravesical Sacituzumab Tirumotecan for 6 weeks

Group Type EXPERIMENTAL

Sacituzumab tirumotecan

Intervention Type DRUG

Intravesical administration

Rescue medication

Intervention Type DRUG

Participants are allowed to take rescue medication for stomatitis or oral mucositis. At the discretion of the investigator, participants are provided with a prescription for rescue medications. Recommended rescue medications are antihistamine, histamine-2 (H2) receptor antagonist, acetaminophen or equivalent, dexamethasone or equivalent infusion or steroid mouthwash (dexamethasone or equivalent), antiemetic medications, oral nystatin suspension or antifungal medications, antidiarrheal agents, antiemetic agents, opiate and non-opiate analgesic agents, appetite stimulants, and granulocyte and erythroid growth factors.

Supportive care measures

Intervention Type DRUG

Participants are allowed to take supportive care measures for the management of adverse events associated with study intervention at the discretion of the investigator. Artificial tear drops or gel may be given as a supportive care for Ocular Surface Toxicity.
