Risk Enabled Therapy After Initiating Neoadjuvant Chemotherapy for Bladder Cancer (RETAIN)

The aim of this study is to evaluate a risk-adapted approach to the treatment of muscle invasive bladder cancer. Each baseline transuretheral resection of bladder tumor (TURBT) sample will be sequenced while proceeding with neoadjuvant accelerated methotrexate, vinblastine, doxorubicin, and cisplatin (AMVAC) chemotherapy. Based on the mutational profile and the post AMVAC TURBT findings, patients will be treated with active surveillance (experimental arm), or standard of care intravesicle therapy, chemoradiation or surgery. We hypothesize that this approach will lead to non-inferior metastasis-free survival at 2 years, while preserving the bladder and thus quality-of-life for a proportion of patients.

Association Between Irrigation Fluid Absorption and Perioperative cfDNA Dynamics After TURBT

This prospective observational cohort study aims to evaluate the association between intraoperative irrigation fluid absorption and perioperative cell-free DNA (cfDNA) dynamics in patients undergoing transurethral resection of bladder tumor (TURBT). Eligible patients with suspected or confirmed bladder cancer scheduled for TURBT will be enrolled. Intraoperative irrigation fluid absorption volume will be recorded, and peripheral blood samples will be collected before surgery and within 24 hours after surgery for cfDNA extraction and mutation analysis. The study will assess whether irrigation fluid absorption volume is associated with changes in cfDNA concentration, tumor-related mutation detection, and clinicopathological features, including tumor stage, grade, size, number, invasion depth, concomitant carcinoma in situ, operative time, resection depth, and intraoperative blood loss. Patients will also be followed for postoperative recurrence, progression, metastasis, and other adverse oncological outcomes. This study may provide preliminary evidence for understanding perioperative tumor-related molecular changes during TURBT and may help improve risk stratification, perioperative management, and postoperative follow-up strategies for patients with bladder cancer.

AN0025 and Pembrolizumab Combination in Advanced Solid Tumors

This is an open-label, multicenter, phase Ib study to evaluate the safety and preliminary efficacy of AN0025 in combination with pembrolizumab in patients with locally advanced/metastatic tumors. It will include a dose-limiting toxicity observation phase followed by an expansion phase. All enrolled patients will be treated with AN0025 and Pembrolizumab until the patient experiences disease progression, unacceptable toxicity or withdraws consent, or for a maximum of 35 cycles (approximately 2 years). The dose of pembrolizumab will remain constant at 200 mg every 3 weeks (Q3W) for each dose level of AN0025 and in each cohort.
