Gene Therapy in Treating Patients With Advanced Bladder Cancer
Bu çalışma, ileri evre mesane kanseri (bladder cancer) olan hastalarda bir gen terapisini (Ad5CMV-p53 gene) incelemiştir. Çalışmaya, platin bazlı kemoterapiye dirençli, kasa yayılmış veya belirli özellikler taşıyan mesane kanseri hastaları katılabilmiştir. Çalışma Faz 1 aşamasında yürütülmüş ve tamamlanmıştır.
