Precise Neoadjuvant Chemoresection of Low Grade NMIBC
Sponsor: University of Bern
Summary
Based on the unmet clinical need to reduce invasiveness of treatment of low grade NMIBC, the investigators conduct this prospective, open label, single arm and single center phase II trial. The investigators aim to use drug screens in PDOs to guide neoadjuvant intravesical instillation therapy with either Epirubicin, Mitomycin C, Gemcitabine or Docetaxel to achieve chemoresection NMIBC.

Interventions
Epirubicin
In PDOs from patients that show highest response to Epirubicin, this drug will be instilled intravesically once weekly for 6 times. Epirubicin will be used as a concentrate for injection/instillation 2 mg/ml in total 50mg per vial. Prior to use, the concentrate for injection is diluted with 25ml of 0.9% saline solution to obtain the final Solution with 1mg/ml of Epirubicin.
Mitomycin
In PDOs from patients that show highest response to Mitomycin, this drug will be instilled intravesically once weekly for 6 times. Mitomycin C will be used as 20mg dry powder. Prior to use, the powder will be dissolved in 50ml of 0.9% saline solution according to the manufacturer instructions
Gemcitabine
In PDOs from patients that show highest response to Gemcitabine, this drug will be instilled intravesically once weekly for 6 times. Gemcitabine will be used as 2000 mg/50ml. For intravesical application, 1000mg of gemcitabine (corresponding to 25ml) will be diluted in 25ml 0.9% saline solution, to obtain the gemcitabine concentration of 1000mg/50ml used for instillation.
Docetaxel
In PDOs from patients that show highest response to Docetaxel, this drug will be instilled intravesically once weekly for 6 times. Docetaxel will be used as 140mg/7ml solution. For intravesical application, 48.825ml of saline will be added to 1.875ml Docetaxel solution (according 37.5mg of Docetaxel). The concentration of this solution is 0.74mg/ml by a total volume of the instillation solution of 50,7.
