Sponsored by JSC NextGen · Phase 2/3, Interventional, and Treatment
To evaluate the efficacy and safety of Neovasculgen in interstitial cystitis with Hunner's lesions to reduce cicatricial changes in the bladder caused by electrocoagulation and to prevent secondary bladder shrinkage with a decrease in its volume.
236 studies on the registry are indexed under Cystitis, Interstitial; 35 are open to participants now.
This study's planned enrollment of 180 is above the median of 51 across 158 interventional studies indexed under Cystitis, Interstitial.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Receiving combination therapy: coagulation of Hunner's lesions of the bladder followed by hydrobougienage and intradetrusor administration of Neovasculgen
Drug: Neovasculgen®
Control group, receiving basic therapy: coagulation of Hunner's lesions of the bladder followed by hydrobougienage
Drug: Placebo
The bladder is hydro-bougienated, Hunner's lesions are identified, and electrocoagulation is performed using a resectoscope using standard techniques, followed by repeated hydro-bougienage of the bladder. The drug/placebo is then administered using a cystoscopic injection needle inserted into a rigid or flexible cystoscope inserted through the urethra into the bladder. The drug/placebo is injected evenly along the edges of the coagulated area and into the Hunner's lesion itself, and then evenly along the bladder walls in a series of 30 injections.

Number of participants who experienced a treatment effect at study end, within 1 year from treatment start to study end.
Conclusions about the effectiveness of treatment will be made based on the results of cystoscopies, patient complaints and questionnaire results.
Time frame: within 1 year from treatment start to study end
