저등급 NMIBC의 정확한 신보강 화학절편 (POLO)
환자 유래 오가노이드의 약물 선별을 통해 유도되는 저등급 NMIBC의 정확한 신보강 화학절편: 단일 센터, 공개 라벨, 2상 시험
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.

상세 설명
Bladder cancer is a disease of the elderly patient and related to several interventions and operations. Patients with a low risk non-muscle invasive bladder cancer (NMIBC) are treated by transurethral resection of the bladder tumor (TURBT). Due to the high recurrence rate of approximately 50% within 2 years of diagnosis, patients are followed in outpatient clinic by cystoscopy for at least 5 years.
Beside recurrence of low grade NMIBC to low grade disease, progression to higher grade or stage is infrequent to rare. Therefore, expectant management and actives surveillance seems to be an option for selected patients that are unfit for surgery. Moreover, intravesical chemoresection has been attempted in order to avoid surgery. However, all patients were treated with the same chemotherapeutic agent and anticipated response rates were missed.
At least four different drugs have been used in daily routine and/or clinical trials for instillation therapies in NMIBC. Namely, Epirubicin, Mitomycin C, Gemcitabine and Docetaxel have been investigated and administered.
The molecular landscape of NMIBC is heterogeneous. Not only the mutational pattern but also the transcriptomic characteristics vary between different NMIBC. Although different agents are used on a routine daily bases and in clinical trials, they have not been administered based on the molecular landscape or biological likelihood of response.
The investigators recently developed a pipeline for the generation of patient derived organoids (PDO) in NMIBC. In brief: The bladder cancer is sampled during TURBT. Generation of organoids has been carefully optimized in order to yield high viability from each sample. Beside confirmation of similarities of the molecular landscape between parental NMIBC and subsequent PDO (in approx. 30 samples), the investigators established a standardized protocol to perform drug screens on these PDOs.
In this trial (POLO Trial) the investigators aim to generate PDOs from bladder cancer biopsies that are harvested in the outpatient clinic. Subsequent drug screen in PDOs for Epirubicin, Mitomycin C, Gemcitabine and Docetaxel will identify the most effective agent in this given patient. Prior TURBT, patient will receive 6 intravesical instillations with the identified agent as neoadjuvant treatment in order to perform chemoresection of the tumor. Three months after initial diagnosis, TURBT will be performed as the standard treatment and to confirm response rate of precise chemoresection.

실험적: Epirubicin
Patients in that PDOs show highest response to this drug in-vitro will be treated with Epirubicin. |

Quality of life measured with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). It corresponds to a functional Scales & Global Health Status; a higher score indicates a better outcome (a higher level of functioning or a better quality of life). The score minimum is 0 and maximum 100. |

The quality of life is completed with a Symptom & Concern Scale specific for NMIBC called European Organisation for Research and Treatment of Cancer 24-Item Non-Muscle-Invasive Bladder Cancer Module (EORTC QLQ-NMIBC24). This Symptom & Concern Scale has also a minimum score of 0 and a maximum of 100. A higher score indicates a worse outcome (a greater burden of symptoms or high symptomatology). |
