What the trial is, and whether it could suit you
The goal of this clinical trial is to learn if the drug Alpha1H works to treat low-to-intermediate risk non-muscle-invasive bladder cancer in adults. It will also learn about the safety of drug Alpha1H.
The main questions it aims to answer are:
* Does giving drug Alpha1H before surgery lower the risk of cancer returning or worsening compared to standard care alone?
* Is drug Alpha1H safe and well-tolerated by participants? Researchers will compare participants receiving drug Alpha1H before standard surgery to participants receiving standard care alone to see if drug Alpha1H lowers the risk of cancer returning or progressing.
Participants will:
* Be randomly assigned to receive either drug Alpha1H before surgery or standard care alone.
* Receive drug Alpha1H directly into the bladder 6 times over about 1 month if assigned to the Alpha1H group.
* Hold the liquid in the bladder for up t

* Negative pregnancy test at screening for women of childbearing potential.
* Women of childbearing potential must agree to use highly effective contraception methods throughout study participation; men of childbearing potential must refrain from donating sperm during the study.
* Ability to retain bladder contents for 2 hours.
Exclusion Criteria:
* Patient with non-papillary tumor appearance at the time of initial cystoscopy.
* Previous history of T1 or high-grade disease in recurrent tumors.

* Prior radiotherapy or systemic chemotherapy.
* WHO performance status of 3 or 4.
* Any other investigational agent or non-marketed product within one month prior to Visit 1 and during the trial.
* Known active HIV infection, defined as detectable HIV viral load at screening.
* Active hepatitis B virus (HBV) infection, defined as hepatitis B surface antigen (HBsAg) positivity with detectable HBV DNA at screening.
* Active hepatitis C virus (HCV) infection, defined as anti-HCV antibody positivity with detectable HCV RNA at screening in a patient not on stable antiviral treatment.
* Any concurrent illness that may render a participant ineligible or limit compliance with study requirements.
