Irinotecan Liposomes Combined with Epirubicin in Recurrent Non-muscle Invasive Bladder Urothelium Carcinoma After Anthracyclines Treatment

Phase 1
Not yet recruiting
Conditions
Non-Muscle Invasive Bladder Urothelial Carcinoma
Interventions
Registration Number
NCT06766266
Lead Sponsor
First Affiliated Hospital of Chongqing Medical University
Brief Summary

The goal of this clinical trial is to learn the dose-limiting toxicity of the new combined treatment with irinotecan liposomes (intravenous injection) and epirubicin (intravesical instillation) in anthracyclines treatment-failed non-muscle invasive bladder cancer adults.

It will also learn if the combined treatment works to treat these patients. Additionally, the safety and biological mechanisms of the combined treatment will also be explored.

The main questions it aims to answer are:

* Does the combined treatment of irinotecan liposomes and epirubicin reverse anthracyclines resistance of participants?

* What medical problems do participants have after taking the combined treatment of irinotecan liposomes and epirubicin?

* What biological mechanisms underlie the effect of irinotecan liposomes on anthracyclines resistance? Participants will be classified into Arm A and Arm B.

* Arm A: Participants will receive an intravenous injection of irinotecan liposomes once every two weeks for one month, along with intravesical instillation of epirubicin once a week for one month. Patients will be evaluated by two professional urologists; those with a complete response or partial response will undergo transurethral resection of bladder tumor (TURBT) and intravesical therapy. Patients with stable or progressive disease will receive subsequent treatment at the investigator's discretion. Participants are required to visit the hospital for physical examination every two weeks.

* Arm B: In the first month after TURBT surgery, participants will receive intravenous injection of irinotecan liposomes once every two weeks for one month, and intravesical instillation of epirubicin once a week for one month, followed by once a month for six months. Participants are required to visit the clinic for physical examination once every two weeks in the first month, and once every three months after that.

* Keep a diary of their symptoms during the study period.

GroupInterventionDescription
Arm A: TURBT unresectableIrinotecan liposome II combination therapy regimenIf the recurrent tumor can't be excised by TURBT, participants will be assigned to this arm. Participants in this arm will complete the neoadjuvant therapy with irinotecan liposome (intravenous injection, once every two weeks for 1 month, dose increasing regimen: 37.6 mg/m2 and 56.5mg/m2) and epirubicin (intravesical instillation, once a week for 1 month, 50 mg), and the therapeutic effect was evaluated by pelvic enhanced MRI and cystoscopy. Judged by two urologists with senior professional title, patients with complete response and partial response were treated with TURBT and intravesical therapy. Patients with stable disease or progressive disease received subsequent therapy at the investigator's discretion. Participants will visit the clinic once every 2 weeks for checkups and tests.
Arm B: TURBT resectableIrinotecan liposome II combination therapy regimenIf the recurrent tumor can be excised by TURBT, participants will be assigned to this arm (Arm B). Participants in this arm will complete TURBT with immediate intravesical instillation of epirubicin (50 mg) within 24 hours after surgery. During the induction phase (the first 1 month after surgery), participants will receive the combined therapy with irinotecan liposome (intravenous injection, once every two weeks for 1 month, dose increasing regimen: 37.6 mg/m2 and 56.5mg/m2) and epirubicin (intravesical instillation, once a week for 1 month, 50 mg). In the next 6 months, participants will continue the intravesical instillation treatment with epirubicin (once a month, 50 mg). Participants will visit the clinic once every 2 weeks for checkups and tests in the first month, and once every 3 months after the first month.

Safety and adverse events2 months

The description of adverse events will be coded according to MedDRA terminology and graded according to NCI-CTCAE v5.0.

Objective remission rate (Arm A available)4 weeks

The proportion of patients with complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD) after treatment was calculated according to the recognized response evaluation criteria (such as New response evaluation criteria in solid tumours: Revised RECIST guideline , version 1.1).

CR: All tumor target lesions disappeared and no new lesions appeared. PR: The sum of maximum diameter of tumor target lesions decreased by ≥30%; SD: The sum of the maximum diameter of tumor target lesions did not shrink to PR, or increase to PD; PD: The sum of the maximum diameters of tumor target lesions increases at least ≥20%, or new lesions appear.

Recurrence-free survival (Arm B available)3-6 months

The time from TURBT surgery to recurrence or the end of follow-up.

The levels of DNA double-strand break and homologous recombination repair in tumor tissues are detected
