A Study to Learn About the Study Medicine PF-08052667 in People With Bladder Cancer

The purpose of this study is to learn how a new medicine called PF-08052667 works when used by itself or together with another medicine called Bacillus Calmette Guerin (BCG), and/or a medicine called sasanlimab. This study is for adults who have a type of bladder cancer that hasn't spread into the muscle layer of the bladder but is more likely to come back or grow. It includes people whose cancer has come back or hasn't gone away after receiving standard treatments like BCG. It may also include people who, based on their doctor's opinion, cannot receive standard treatments or those treatments are not available to them. The study has three parts: * Part 1 (monotherapy dose escalation) will test PF-08052667 as a single-agent at increasing dose levels in participants with certain bladder cancer whose disease has worsened on or after standard treatments. * Part 2 (combination dose escalation) will test PF-08052667 in combination with BCG and/or sasanlimab (fixed dose) in participants with certain bladder cancer whose disease has worsened on or after standard treatments. * Part 3 (dose optimization and expansion) will further test PF-08052667 as a single agent or in combination with BCG and/or sasanlimab, at the dose(s) based on findings from Part 1 and Part 2 in participants with certain bladder cancer including those who has never received standard treatments. All participants will receive the study drug PF-08052667. Only participants in Part 2 and Part 3 of the study will also receive BCG and/or sasanlimab. PF-08052667 will be given as an intravesical infusion, which means it will be injected directly into the bladder. Sasanlimab will be given as a subcutaneous injection, which means it will be injected under the skin. For all parts, treatment with study medicines will continue until either a participant has decided to stop taking part in the study or is asked to leave the study for various reasons or up to about 2 years, whichever occurs first. Duration of trial participation for each participant will vary as long-term follow-up will continue after treatment discontinuation until loss to-follow-up or death, or until the study is stopped by the sponsor.

Exploration of Novel AI-enabled Blue Light Enhanced Cystoscopy

Blue light cystoscopy (BLC) is a diagnostic procedure in bladder cancer where the inside of the bladder is observed with a camera to detect bladder lesions. Unlike regular white light cystoscopy, blue light cystoscopy makes use of a drug that induces fluorescence under blue light preferentially in neoplastic and malignant cells that helps visualize bladder lesions during the cystoscopic procedure. Blue light cystoscopy has shown to improve detection of bladder cancer. Cystoscopy, including blue light cystoscopy, is a procedure involving assessment of the visual appearance of the bladder surface, leading to decisions of taking biopsies, remove suspicious areas and assign treatment options. The assessment is subjective and has a large operator variability. These shortcomings show an opportunity for computer aided detection (CADe) medical device to add value to both clinicians and patients. The objective of this data collection study is to build a high-quality, diverse data set of video, image recordings and relevant clinical data from BLC procedures performed as part of routine clinical practice to train a computer-aided detection (CADe) algorithm for real- time lesion detection during cystoscopy. The data will be used to support the training, non-clinical technical development and testing of such AI algorithms for use during cystoscopy and to provide documentation needed for training of such algorithms and to assist in guiding future validation of such algorithms. Exploratory purposes of the study is to use data to explore future AI algorithms in bladder cancer, such as computer-aided diagnosis (CADx) AI algorithms, image enhancement and cystoscopy improvement algorithms, including bladder mapping, tumor visualization, cystoscopy documentation, and combination models of image and clinical data including risk assessment, clinical outcomes, and disease modeling

A Phase I Intravesical PPM Therapy for NMIBC

This clinical trial is to determine the safety and effectiveness of an investigational bladder cancer drug named "PLZ4-coated paclitaxel-loaded nanoscale micelle (PPM)." PPM is tiny particles that contain the chemotherapy drug paclitaxel. PLZ4 is a molecule that can possibly guide PPM to specifically target and deliver paclitaxel into and kill bladder cancer cells. In this trial, PPM will be instilled into the bladder cavity to treat bladder cancer that does not invade into the muscle layer of the bladder and that has failed the treatment of another drug Bacillus Calmette-Guérin (BCG). Up to 29 patients will be enrolled into the trial. The main goal of this trial is to determine the dose of PPM for future clinical trials, assess the toxicity and obtain preliminary data regarding its effectiveness.

Is Prolonged Systemic Immunotherapy Necessary After Achieving Tumor-free Status in Patients With Extensive Transurethrally Unresectable Very-high-risk NMIBC?

Patients with extensive transurethrally unresectable very-high-risk non-muscle-invasive bladder cancer (NMIBC) may achieve a tumor-free status after systemic immunotherapy-based bladder-sparing treatment combined with transurethral resection of bladder tumor (TURBT). However, the optimal duration of systemic immunotherapy after achieving a tumor-free status remains uncertain. Prolonged treatment may increase toxicity, treatment burden, and cost, while some patients may maintain durable disease control without continued therapy. This randomized study aims to evaluate whether active surveillance after achieving tumor-free status is a feasible alternative to continued systemic immunotherapy in patients with extensive transurethrally unresectable very-high-risk NMIBC. Patients will initially receive systemic immunotherapy-based treatment followed by disease evaluation using cystoscopy with biopsy and/or TURBT, urine cytology, urinary tumor DNA (utDNA), and imaging assessments. Patients who achieve tumor-free status after treatment and complete resection of visible disease will be randomized to either active surveillance or continued systemic immunotherapy. The study will evaluate recurrence outcomes, bladder preservation, progression, safety, and patient management strategies following achievement of tumor-free status. The trial also aims to explore the role of urinary tumor DNA in identifying patients who may safely undergo treatment de-escalation and active surveillance.

Hyperthermic Intravesical Chemotherapy (HIVEC) in BCG-Non-Responsive High-Grade NMIBC Patients

This is a Phase II, prospective, single-arm, open-label clinical study evaluating hyperthermic intravesical chemotherapy (HIVEC) with Mitomycin C in patients with high-grade, non-muscle-invasive bladder cancer (NMIBC) who are BCG-non-responsive or BCG-intolerant and are ineligible for, or refuse, radical cystectomy. Mitomycin C is an approved medicinal product used within routine clinical practice and administered with a CE-marked recirculation device (BRS Combat system) that maintains the solution at approximately 43°C for 60 minutes. The treatment schedule consists of 6 weekly induction instillations followed by 9 monthly maintenance instillations. The co-primary objectives are to describe the safety and toxicity profile of HIVEC, including treatment discontinuations due to procedure-related toxicity, and to estimate the 12-month recurrence-free survival (12moRFS). Secondary objectives include characterizing patterns of non-muscle-invasive and muscle-invasive recurrences, bladder cancer-specific survival, overall survival, and quality of life. Approximately 50 patients will be enrolled in this single-center pilot study to generate exploratory safety and efficacy data in this high-risk population and to support the design of future randomized trials

Vesical Imaging-Reporting and Data System (VI-RADS) Followed by Photodynamic Trans-urethral Resection of Bladder Tumours (PDD-TURBT) to Avoid Secondary Resections (Re-TURBT) in Non-Muscle Invasive Bladder Cancers (NMIBCs)

Background: In European Association of Urology (EAU) Guidelines, the vast majority of non-muscle-invasive bladder cancers (NMIBCs) undergo a primary transurethral resection of the bladder tumor (TURBT) followed by a repeat TURBT (Re-TURBT). The Re-TURBT is recommended due to the possibility of residual bladder cancer but is unnecessary in many cases by constituting overtreatment. Currently, no diagnostic strategy or predictive tools have been implemented to further stratify who does or does not benefit from Re-TURBT. Recently, an MRI-based Vesical Imaging Reporting and Data System (VI-RADS) score has been developed to stage as to the preoperative probability of muscle invasion, which could potentially exclude those who do not require a Re-TURBT when a primary high-quality resection is delivered. As such, performing TURBT with standard white light (WL) cystoscopy is known to miss many bladder tumours, which may be poorly visible, and a technique known as with photodynamic diagnosis (PDD) results in lower residual tumor and lower early intravesical recurrence rates. PDD is performed using violet light to improve the detection of these lesions not easily visible with WL cystoscopy. Methods/Aims: The investigators propose an Italian, single-center, phase IV, open-label, non-inferiority, randomized controlled trial, in which participants (n=112) who had already received a mpMRI/VI-RADS score, are randomized to receive PDD-TURBT, no Re-TURBT versus standard of care represented by conventional WL-TURBT followed by WL-Re-TURBT. The primary outcome is proportions of early recurrence in the urinary bladder. Secondary outcomes will include proportions of late BCa recurrence, late disease-free interval, time to progression to MIBC, patient's quality of life assessment, and cost-analysis. Perspective: The CUT-less trial aims to respond to this unmet need through a non-inferiority randomized clinical study potentially shaping the perspective for a paradigm shift towards a more personalized, socially, and economically sustainable updated NMIBC therapeutic pathway. Implications: The current clinical trial proposal is aiming to achieve a paradigm shift in the oncological and socio-economical management of urothelial malignancies of the urinary bladder. Our first concern is indeed to guarantee a safe and ground-breaking strategy to manage the pathway of such patients in order to guarantee the non-inferior oncologic safety (and possibly superiority) when compared to the current standard of care. Additionally, if our hypotheses are confirmed, the investigators will be able to significantly relieve these patients from the oncologic burden of an already invasive and arduous bladder cancer care path. Finally, safely avoiding an unnecessary, expensive surgical procedure will bring significant social and economic benefits to the EU healthcare system and possibly worldwide.
