About this trial

The main objectives of this study are to determine the feasibility and safety of Belzupacap Sarotalocan (AU-011, bel-sar) treatment of bladder cancer utilizing focal injections with or without laser application.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Ta HG papillary disease with or without CIS; OR

Disqualifiers

Any additional malignancy that requires active treatment, unless deemed appropriate after discussion by the Investigator with the trial's Medical Monitor.

Used an investigational drug or medical device within 30 days or 5 half-lives (whichever is longer) of Visit 1 or be concurrently enrolled in another investigational trial.

Active bacterial, fungal, or viral infections - all prior infections must have resolved following optimal therapy and subject must be off all systemic anti-infective agents.
