Clinical trials

The preclinical pharmacological mechanism of YH02 injection is well established. By constructing a vector expressing MMP13, introducing a human S promoter, and genetically modifying the capsid protein, the virus's permeability, tumor targeting capability, and infection efficiency were significantly enhanced. Preclinical pharmacodynamic studies demonstrated that YH02 exhibits potent tumor growth inhibitory effects in various human-and murine-derived solid tumor models (including breast cancer, liver cancer, and melanoma). Given that oncolytic virus therapies already have approved products with demonstrated safety and efficacy worldwide, this study may offer potential clinical benefits for patients with advanced solid tumors who have failed standard treatments. YH02 injection has undergone an open-label, dose-escalating, and expanded Phase I clinical study in China aimed at evaluating the safety, tolerability, biodistribution characteristics, viral clearance, and immunogenicity of intratumoral administration of YH02 injection in patients with advanced solid tumors who have failed adequate standard therapy and lack effective treatment options, while preliminarily investigating its efficacy. No high-grade adverse drug reactions (ADRs) have been observed to date, nor were there any serious adverse events (SAEs), severe adverse drug reactions (SUSARs), or fatal events. The clinical safety and tolerability of this product for intratumoral administration are favorable.

Rationale and Objective: The purpose of this study is to evaluate the clinical efficacy and safety of a novel multimodal analgesia regimen, combining transversus abdominis plane block (TAPB) with patient-controlled intravenous analgesia (PCIA), in improving postoperative gastrointestinal function recovery in patients undergoing major abdominal surgery. Study Design and Interventions: This is a prospective, single-center, randomized, double-blind, parallel-controlled trial. A total of 132 eligible patients (aged 18-80 years, ASA I-III, scheduled for elective small bowel or colorectal surgery) will be randomly allocated to one of three groups (n = 44 per group) to receive distinct postoperative analgesia regimens: Group R-S: 0.375% Ropivacaine TAPB + Sufentanil PCIA; Group LB-S: 266 mg Liposomal Bupivacaine TAPB + Sufentanil PCIA; Group LB-O: 266 mg Liposomal Bupivacaine TAPB + Oxycodone PCIA. Primary Outcome: The primary outcome is the area under the curve (AUC) of the I-FEED scoring system within the first 7 postoperative days, which comprehensively reflects the overall trajectory of gastrointestinal function recovery. Hypothesis: The investigators hypothesize that the combination of long-acting Liposomal Bupivacaine TAPB (for prolonged somatic pain relief) and Oxycodone PCIA (for precise visceral pain control via dual u and k receptor agonism) will synergistically attenuate the perioperative stress-inflammatory response. Consequently, this regimen is expected to significantly mitigate postoperative ileus (POI) and accelerate the recovery of gastrointestinal motility

This is a single-center, randomized, single-blind, parallel-group clinical trial. The study aims to compare the analgesic efficacy of liposomal bupivacaine versus ropivacaine for transversus abdominis plane (TAP) block in patients undergoing laparoscopic cholecystectomy. Eligible participants will be randomly assigned to receive either liposomal bupivacaine or ropivacaine for TAP block during surgery. The primary outcome is the dynamic NRS pain score at 24 hours after surgery. Secondary outcomes include static and dynamic NRS pain scores at multiple time points, QoR-15 recovery quality, time to first rescue analgesia, analgesic consumption, gastrointestinal function recovery, length of hospital stay, and adverse events. Participants will be followed up to 3 months after surgery to evaluate the incidence of chronic post-surgical pain (CPSP). All participants will receive routine clinical care, and participation is voluntary.

This prospective, multicenter, non-interventional, observational, real-world study was designed to evaluate the safety and efficacy of an adebrelimab-based regimen in patients with advanced solid tumors.
