New drug combo aims to save bladders in cancer fight
NCT ID NCT01495676
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial tested whether adding gemcitabine to standard cisplatin and radiation therapy could help control muscle-invasive bladder cancer while preserving the bladder. About 69 patients were enrolled to compare the combination against standard treatment. The study was terminated early, so firm conclusions are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- gemcitabine and cisplatin
- What this could lead to
- If successful, this could offer a bladder-sparing treatment option for muscle-invasive bladder cancer, avoiding the need for radical surgery.
- What could go wrong
- This trial was terminated early with only 69 participants, so results are limited. The combination may increase side effects without improving disease control.

Inclusion Criteria: * Muscle invasive urothelial cancer (front line or following the progression of a superficial tumor), pT2-pT3 stage without lymphatic impairment (N0) and without detectable metastases (M0). An optimal macroscopic resection (TURB) have to be performed * The proof of invasive tumor to the muscle should be brought by a transurethral resection under anaesthesia less than 8 weeks before or, in the absence, by superficial biopsies and formal imaging. Multiples biopsies in the bladder must also be performed. * Age ≥ 18 years * Life expectancy ≥ 6 months * Kanorfsky index ≥ 70 % (WHO 0, 1, 2) * Biological criteria: neutrophils ≥ 1500/mm3, Platelets ≥ 100 000/mm3, haemoglobin ≥ 10 g/dl, creatinine clearance \> 60 ml/mn * No distant metastases (Thorax, abdomen, and pelvic CT-scan, bone scan) * Efficient contraception for premenopausal women, maintained during the whole treatment and up to two months after the completion of radiotherapy. * No radiotherapy or chemotherapy history except for in situ bladder lesions. * No carcinological history except for non melanoma skin tumours, in situ uterine cervix cancer * No contraindication to gemcitabine or cisplatin. * No contraindication to radiotherapy * Information letter and informed consent signed * Patient covered by social security Exclusion Criteria: * Bladder tumors without any muscle infiltration * Epidermoid carcinoma or adenocarcinoma * Distance metastases or extrapelvic node positivity * Severe digestive history (ulcerative colitis, complicated diverticulitis) * Pregnancy and breast feeding
