Urothelial Carcinoma Bladder

This study is being conducted to evaluate the safety and tolerability of UGN-501 administered intravesically in adult participants with recurrent non-muscle invasive bladder cancer (NMIBC) and to determine the recommended Phase 2 dose (RP2D).

This is a first-in-human Phase 1b, 2-part, multicenter open-label clinical study to evaluate safety and efficacy of a Nectin-4 radiopharmaceutical (\[225Ac\]Ac-AKY-1189) in patients with locally advanced or metastatic solid tumors and to establish the maximum tolerated dose (MTD) or maximum administered dose (MAD) and the recommended Phase 2 dose.

This is a single arm, Phase II trial involving the use of atezolizumab plus platinum and etoposide for patients with locally advanced urothelial cancer. The primary goal of this trial is to assess the pathologic complete response rate at cystectomy in patients after being treated with a combination therapy of atezolizumab, platinum, and etoposide.

This is a Phase I/II and multicenter study designed to evaluate the efficacy and safety of 4SCAR-T cells in participants with locally advanced or metastatic urothelial bladder cancer (UBC) who have no further treatment available.

Currently, the standard of care for female patients undergoing radical cystectomy includes the removal of the bladder, pelvic lymph nodes, anterior vagina, uterus, fallopian tubes and ovaries. Removal of female ancillary organs, both in pre and post-menopausal stages is associated with reduction in various quality of life metrics, including sexual health, cognitive decline and depression. Furthermore, removal of ovaries has been associated with increased cardiovascular events, metabolic acidosis, osteoporosis and bone fractures. In premenopausal women, the removal of the ovaries is associated with increased all-cause mortality. From an oncologic standpoint, multi institutional retrospective reviews have demonstrated certain pre-operative radiographic and cystoscopic risk factors that are associated with bladder cancer involvement of female reproductive organs. The absence of these unfavorable risk factors may provide an opportunity to spare women from undergoing unnecessary reproductive organ removal during RC. In doing so, this may eliminate the associated sequelae of removing these additional organs while also providing acceptable oncologic care. The investigators thus propose a decision tool to stratify women undergoing radical cystectomy as favorable and unfavorable for reproductive organ sparing radical cystectomy. This decision tool classification will be used to decide which patients will undergo reproductive organ sparing radical cystectomy versus radical cystectomy in this study.

The primary objective of this Phase I study is to establish the safety of adjuvant concurrent immunotherapy and radiation therapy for urothelial bladder cancer.

Bladder cancer (BC) is the 6th most common tumor in Europe, with over 540,000 new cases globally each year. While 75% of cases are non-muscle-invasive and treated bladder-preservingly, muscle-invasive, non-metastatic BC requires radical cystectomy (RC), often with neoadjuvant chemotherapy. RC has one of the highest complication rates in urology, and rehabilitation focuses on mitigating functional impairments, restoring physical and mental capacity, and enabling a swift return to daily life. The ERAS (Enhanced Recovery After Surgery) protocol has shown benefits in reducing hospital stays without increasing complications in RC. Prehabilitation studies in cancer patients have demonstrated improvements in strength and fitness, though without significant reductions in complications or mortality. This prospective randomized study, conducted over three years at the University of Munich, will evaluate the effect of preoperative physical activity on perioperative morbidity (primary endpoint). Secondary endpoints include quality of life, hospital stay, mortality, and postoperative physical activity. The intervention group will target 8,000-10,000 daily steps for four weeks preoperatively, monitored via pedometers. Follow-ups will assess physical activity and quality of life at specific intervals pre- and post-surgery.

This phase I study evaluates intravesical calcium electroporation (CaEP) with a new transurethral electrode. The study is primarily designed to assess the safety of CaEP and secondarily, to preliminary explore the efficacy in patients with limited alternative therapies. The anticipated benefits and structured safety precautions justify the ethical conduct of the investigation.

VET3-TGI is an oncolytic immunotherapy designed to treat advanced cancers. VET3-TGI has not been given to human patients yet, and the current study is designed to find a safe and effective dose of VET3-TGI when administered by direct injection into tumor(s) (called an intratumoral injection) or when given intravenously (into the vein) both alone and in combination with atezolizumab in patients with solid tumors (STEALTH-001).

The aim of this study is to evaluate the effect of Verity-BCG in patients with intermediate and high-risk non-muscle-invasive bladder cancer (NMIBC) and to compare our findings to the standard of care BCG formulation, OncoTICE (BCG) in order to examine our hypothesis that Verity-BCG is at least non-inferior to OncoTICE in achieving 24-month Recurrence Free Survival in NMIBC patients who are at high risk of recurrence and have never been treated with intradermal or intravesical BCG before, with the exception of tuberculosis vaccination in childhood.

Study REL-NDV01-303 is a Phase 3, open-label, multi-center study to determine the safety and efficacy of NDV-01 in adult participants with NMIBC. The study will include two cohorts: * Cohort 1: a randomized, open-label, parallel group, multi-center, Phase 3 study evaluating the efficacy and safety of the NDV-01 versus observation in participants with histologically confirmed IR-NMIBC. * Cohort 2: an open-label, multi-center, single-arm Phase 3 study evaluating the efficacy and safety of the NDV-01 in two populations of high-risk NMIBC: * Cohort 2a: will include participants with HR-NMIBC who have a biopsy-proven recurrence with CIS ± papillary disease after receiving one or 2 lines of therapy for BCG-unresponsive NMIBC (approved or in development). * Cohort 2b: will include participants with high-risk papillary-only disease (without CIS) NMIBC who have a biopsy-proven recurrence with HG papillary disease after receiving one or 2 lines of therapy for BCG-unresponsive NMIBC (approved or in development). This study will evaluate the safety and efficacy of intravesical administration of NDV-01, and its effect on disease recurrence and progression in patients with NMIBC who have IR disease and have recently undergone a TURBT (Cohort 1) and in patients who have HR BCG-unresponsive disease and who have recurred after first-line therapy for BCG-unresponsive patients - both approved and in development - and are unwilling or unable to undergo radical cystectomy (Cohort 2). Both GEM and DOCE have established safety and efficacy across a range of tumor types, including IR and BCG-unresponsive NMIBC. By combining both GEM and DOCE in an intravesical extended-release formulation, Relmada believes that NDV-01 has the potential to be an agent for second-line therapy in patients who have recurred after first-line therapy in BCG-unresponsive disease, thereby avoiding radical cystectomy. This study will serve as a master protocol for all cohorts included in the study.

The goal of this observational study is to further validate the sensitivity and specificity of Bladder EpiCheck in primary detection of urothelial carcinoma in participants aged 45 years or older presenting with haematuria, compared to cystoscopy and pathology, if performed. Participants will provide a voided urine sample, and data from standard of care haematuria work-up will be collected.

This trial will evaluate the use of combination pembrolizumab and enfortumab vedotin for patients with high grade non-metastatic (cN0/NxMx, no measurable regional lymph nodes, no metastases) upper tract urothelial cancer (UTUC), preferring to forego standard of care radical nephroureterectomy (RNU) surgery. Currently these patients would not be suitable candidates for neoadjuvant trials, as the patients intention is to forego surgery. The patients are also not candidates for metastatic trials, as the patients have no measurable metastasis. The Investigators hypothesize the combination of pembrolizumab and enfortumab vedotin for patients with high grade cN0/NxMx UTUC deferring RNU will lead to event free survival outcomes similar to that achieved by RNU in a historic dataset.

【Treatment of Urothelial Carcinoma】 Treatment for urothelial carcinoma includes surgery, chemotherapy (anticancer drugs), and radiation therapy. Chemotherapy is generally used when metastasis has already occurred at diagnosis and surgery is not curative (metastatic urothelial carcinoma) or when the cancer recurs after local therapy such as surgery or radiation therapy (recurrent urothelial carcinoma). Although there are several recommended treatments for urothelial carcinoma, the options are often limited by side effects and other factors, and these treatments may not be fully effective. Therefore, the development of safer and more effective treatments is desired. 【About the Drugs to be Used in this Clinical Trial】 In this clinical trial, the investigational drug MIKE-1 will be used in combination with nivolumab plus GC (cisplatin gemcitabine), one of the recommended chemotherapy regimens, and subsequently with nivolumab monotherapy for patients with unresectable metastatic or recurrent urothelial cancer. Nivolumab, cisplatin, and gemcitabine are injectable (intravenous infusion), while MIKE-1 is oral. 【Purpose of the Clinical Trial】 The purpose of this clinical trial is to evaluate the efficacy (how much the cancer shrinks or slows down) and safety of the investigational drug MIKE-1 in combination with nivolumab and gemcitabine and cisplatin therapy in patients with untreated unresectable or recurrent urothelial cancer.

This study is being conducted to establish a novel tumor tissue- and blood-based biomarker test to assess early systemic and local response to immunomodulation by BCG immunotherapy in patients with high-risk non-muscle invasive bladder cancer. Responses will be compared between patients with high-risk NMIBC who are being treated with standard of care BCG therapy and those treated with combination chemotherapy. Local and systemic immune monitoring assays will allow early identification of patients who will not benefit from BCG immunotherapy.

Bladder cancer(BC) is the 10th most common cancer globally, with a higher incidence in males than females, being the 6th most common cancer in men with high mortality, causing a societal burden worldwide. Known risk factors include age, gender, cigarettes, genetic factors, and other environmental influences . BC can be classified into non-muscle-invasive BC (NMIBC) and muscle-invasive BC (MIBC) . MIBC exhibits a more aggressive nature, correlates with a higher level of T-stage, and has more significant genetic heterogeneity . Despite comprehensive treatment regimens comprising neoadjuvant chemotherapy, radical cystectomy (RC) and adjuvant immunotherapies, a significant proportion of MIBC patients continue to progress to more advanced stages with limited clinical indicators. Unfortunately, the mechanisms underlying BC initiation, proliferation, and progression remain largely unknown. The occurrence of genetic alterations is believed to be closely linked to BC tumorigenesis. Therefore, investigating the genetic alterations might offer opportunities to further understand biological changes in BC . A key mechanism underlying tumor progression and metastasis is the epithelial-mesenchymal transition (EMT), which is associated with increased invasiveness, chemoresistance, and immune evasion. EMT is characterized by the downregulation of epithelial markers such as E-cadherin (CDH1) and the upregulation of mesenchymal markers like N-cadherin (CDH2), vimentin, Snail, and ZEB proteins . Emerging evidence suggests that junctional adhesion molecule 3 (JAM3) plays a role in EMT and cancer progression, with documented involvement in gastric cancer. However, its significance in MIBC remains poorly understood. Investigating JAM3 expression in MIBC may provide novel prognostic insights and help refine patient stratification for NAC and immunotherapy. Aim: This study aims to analyze JAM3 expression in transurethral biopsies from MIUC patients and correlate it with: * Tumor aggressiveness (grading, staging, and histological features). * Response to neoadjuvant chemotherapy . * Patient survival and disease progression. This study will provide a better understanding of JAM3's role in EMT and MIUC progression, offering potential biomarker-driven insights for treatment stratification. If JAM3 is validated as a prognostic factor, it could guide personalized therapeutic approaches and optimizing NAC outcomes.

This study will compare the efficacy of 9MW2821+toripalimab versus 9MW2821 monotherapy in locally advanced or metastatic urothelial carcinoma patients who have not received any systemic treatment in the metastatic or advanced setting.
