A Clinical Study of Sacituzumab Tirumotecan (MK-2870) in Patients With Bladder Cancer (MK-2870-027)

The goal of the study is to learn about the safety of Sacituzumab Tirumotecan and if people can tolerate it when given in the bladder and find the highest dose that people can take without having certain problems. Researchers will then choose a dose level of Sacituzumab Tirumotecan to use in future studies to learn how well the drug works.

A Phase II Trial of Bicalutamide in Patients Receiving Intravesical BCG for Non-muscle Invasive Bladder Cancer

This is a phase II randomized controlled clinical trial comparing standard induction BCG versus bicalutamide and standard induction BCG among patients with non-muscle invasive bladder cancer.

Mood Alterations in the Patients With Non-Muscle Invasive Bladder Cancer Treated With BCG

The purpose of this study is to evaluate mood changes in patients with Non-Muscle Invasive Bladder Cancer who are receiving intravesical Bacillus Calmete-Guerin (BCG). Patients with Non-Muscle Invasive Bladder Cancer receiving intravesical treatments are eligible to participate in this study. Participation involves providing research blood and urine samples prior to the start of treatment and throughout the treatment course. The study team will also collect participant's medical history and clinical information. Participants will be asked to complete questionnaires and daily mood diaries.

A Study Comparing Standard Treatments in People With Non-Muscle Invasive Bladder Cancer (NMIBC)

The purpose of this study is to compare the effectiveness of different FDA-approved/NCCN-recommended drug treatments for NMIBC. In particular, the FDA-approved drug nadofaragene firadenovec will be compared to usual care with other NCCN-recommended standard treatments for NMIBC (gemcitabine with or without docetaxel, mitomycin, re-treatment with BCG, or pembrolizumab).

Chemoablation Or Bladder Resection With Adjuvant Chemotherapy in Recurrent Non-Muscle Invasive Bladder Cancer

The investigartors will conduct a randomized, multinational study with the aim to assess if the efficacy of a dose dense chemoablation with Mitomycin C (MMC) with adjuvant BCG in non-responding patients is superior regarding long term effect compared to standard treatment with trans urethral resection of bladder tumors (TURBT) and adjuvant intravesical instillation therapy in patients with recurrent Ta LG tumors. The study is a natural follow-up study following the pivotal NICSA trial supported by the Danish Cancer Society that has lead to the initial change in the European guidelines. In order to not only be comparable to current standard, but also to improve clinical outcome and furthermore confirm the previous findings, the investigators here suggest to implement at patient tailored approach through a new multicenter RCT. The investigators hypothesize that chemoablation with MMC in patients with recurrent Ta LG tumors will result in a permanent low recurrence rate in patients with complete response, whereas patients without complete response can be selected for adjuvant BCG which theoretically is more efficient in this select patient group. This will potentially result in a more favorable long term recurrence free survival (RFS) rate compared to the current standard regimen where all patients are treated with TURBT and adjuvant instillation therapy. The incidence of bladder cancer in Denmark is almost 2,000 per year. Of these, 75% have non-muscle invasive bladder cancer (NMIBC). The yearly recurrence rate of NMIBC is approximately 35% and the disease is therefore one of the most costly cancers to manage on a per patient basis, due to the cost of operative procedures, follow-up cystoscopies and instillation therapies

Radiotherapy for BCG-unresponsive Non-muscle-invasive Carcinoma in Situ (CIS) Bladder Cancer: an Open-label, Single-arm, Multicentre, Phase 2 Study

Standard treatment for patients with high-risk NMIBC (high-grade Ta, CIS, or any T1) consists of intravesical Bacillus Calmette-Guerin (BCG) immunotherapy. However, BCG, even administered optimally, does not provide absolute protection and BCG failure is generally considered recurrence or progression during therapy. Patients who are BCG-unresponsive have a 20-40% risk for progression to muscle-invasive bladder cancer within 5 years, and a 50% risk of developing metastatic disease. For these patients, radical cystectomy with pelvic lymph node dissection and urinary diversion is the standard of care. However, many patients are unable to undergo radical cystectomy because of poor performance status and co-morbidities or decline to undergo surgery. Although, several phase II studies have shown promising results, none of the drugs are presently available in Europe. An alternative approach is to investigate a possible role for radiotherapy in good prognosis bladder cancer patients. As there is little existing data in NMIBC, the example of bladder preservation in MIBC will be used for guidance. We aim to evaluate the use of radiotherapy in patients with high-grade non-muscle-invasive bladder cancer who have BCG failure in a single-arm design as per FDA guidelines for this setting. The primary objective is to demonstrate that complete response to treatment 6 months post radiotherapy is seen in more than 30% of patients with BCG-unresponsive, non-muscle invasive carcinoma in situ bladder cancer, unfit or unwilling to undergo radical cystectomy. Patients with BCG unresponsive non-muscle-invasive bladder cancer according to the EAU guidelines will be treated 20 fractions of 2.75 Gy over 4 weeks with the use of radiosensitisers as per local guidelines. Cystoscopy and urine cytology assessments will be performed at 3 and 6 months from the start of radiotherapy. If either assessment is positive, bladder biopsies or TURBT are required. At the 6-month timepoint, biopsy or TURBT is mandatory. Disease assessments beyond 6 months will be at the treating urologist's discretion.

Clinical Trial for Evaluating the Efficacy and Safety of BCG for Therapeutic Use in the Prevention of Postoperative Recurrence of Medium/High-risk Non-muscle Invasive Bladder Cancer (NMIBC)

A phase III multi-center randomized, double-blind and positive-controlled clinical trial for evaluating the efficacy and safety of BCG for Therapeutic Use（BCG） in the prevention of postoperative recurrence of medium/high-risk non-muscle invasive bladder cancer (NMIBC).

RC48 Combined With Tislelizumab for Bladder Sparing Treatment in NMIBC With BCG Treatment Failure and HER2 Expression

This is a prospective, open, single-center clinical study of anti-HER2-ADC combined with PD-1 monoclonal antibody for bladder sparing treatment in non-muscular invasive bladder cancer (NMIBC) patients with HER2-expressing. The study was conducted in accordance with the Good Clinical Practice (GCP). Approximately 20 subjects will be enrolled to evaluate the efficacy and safety of RC48 (RC48 2.0 mg/kg intravenously administered every two weeks) combined with Tislelizumab (Tislelizumab 200 mg intravenously administered every three weeks). Subjects undergo Transurethral resection of bladder tumor (TURBT), imaging diagnosis and pre-treatment biological samples of blood, urine and biopsy tissue. The study will include high-risk NMIBC patients who express HER2, fail after BCG treatment, but refuse to undergo cystectomy or do not meet the requirements for cystectomy. Subjects will receive RC48 and Tislelizumab for two years. BI-DFS were evaluated by cystoscopy, histopathologic examination, laboratory examination, and imaging examination after treatment, and tumor efficacy was evaluated when clinical studies reached the number of subjects specified in the protocol for efficacy evaluation.

Outpatient Laser Ablation of Recurrent Non-muscle Invasive Bladder Cancer

Aim: To investigate the feasibility and tolerability of the Olympus Soltive laser in treatment of large recurrent low-grade Ta tumours in an outpatient setting. Background: Non-muscle invasive bladder cancer (NMIBC) is associated with a high yearly recurrence rate up to to 61%. Patients affected are therefore referred to long-term or even life-long follow-up, which burdens both patients and health care system. Recurrent tumours are most frequently treated with TURBT followed by adjuvant intravesical treatment. Repeat TURBT includes a risk of morbidity from the procedure itself and from general anaesthetics, which the procedure requires. Patients with NMIBC are generally elderly, multi-morbid, and as a result, they often show a poor tolerability of general anaesthetics. Thus, the need for non-surgical treatment modalities is imminent and continuous investigations are performed in the field including active surveillance, chemoresection and device-assisted intravesical chemotherapy. Laser ablation is a technique gaining attention in the treatment of NMIBC, based on the prospects of an outpatient treatment modality, which could prove TURBT and general anaesthesia unnecessary in select patients. Methods: The study will be conducted as a prospective feasibility study. Included patients will undergo outpatient laser ablation using the Olympus Soltive laser under local anaesthetics. Patients will be included from Aarhus University Hospital (Denmark), Fundació Puigvert (Spain), Motol University Hospital (Czech Republic) and Institut Universitaire du Cancer Toulouse Oncopole (France). Data will be reported to the eCRF in the online REDCap web application. The eCRF is stored on a secure server under the responsibility of the Department of Clinical medicine at Aarhus University in Denmark. REDCap is a secure web application for building and managing online surveys and databases. The Database will be in agreement with the laws and regulations of the Danish Data Protection Agency and EU regulations (GDPR). The sponsor will be overall responsible for the data entry in the eCRF, and the validity of the data collected at the specific sites. Each participant will be coded with a unique patient identifier to ensure pseudo anonymity. Perspectives: This study will be the first multinational study with focus on feasibility of outpatient laser ablation of large bladder tumours between 1-3 cm. Outpatient laser ablation of these large tumours has the potential to reduce the number of TURBTs per patient, thus easing the life of patients with non-muscle invasive bladder cancer, with fewer surgical procedures as well as reducing the overall treatment related costs for society. If thulium laser ablation proves effective, the treatment modality would be easily implemented and available based on the small size of the machinery.
