Phase 1/2 Study of HYP-2090PTSA in Patients With Advanced Solid Tumors Harboring KRAS Mutation

This is a multicenter, open-label phase 1/2 study consisting of two parts: dose escalation phase and dose expansion phase. The objective of the dose escalation phase is to evaluate the safety, tolerability and pharmacokinetics of HYP-2090PTSA in patients with advanced solid tumors harboring KRAS mutation and to determine the RP2D. In the dose expansion phase, preliminary efficacy and safety at the RP2D will be further explored in patients with specific cancer harboring KRAS p.G12C mutation.

Clinical Study on the Effectiveness of Diverse Segments Defocus Optimization in Spectacle Lenses for Slowing Myopia Progression

Clinical Trial The goal of this clinical trial is to evaluate the effectiveness of two types of Diverse Segments Defocus Optimization (D.S.D.O.) spectacle lenses in slowing myopia progression in children. It will also assess the safety of these lenses. The main questions it aims to answer are: Do D.S.D.O. lenses reduce the progression of myopia as measured by changes in cycloplegic refraction and axial length? What adverse events do participants experience when wearing D.S.D.O. lenses? Researchers will compare two optical designs of D.S.D.O. lenses (Intervention Group1: Design 1; Intervention Group2: Design 2) to determine their relative efficacy in controlling myopia progression. Participants will: Wear assigned D.S.D.O. lenses daily for 12 months (except during sleep or unavoidable situations). Attend clinic visits at baseline, 3, 6, 9, and 12 months for comprehensive eye examinations. Maintain a diary recording daily wear time, visual symptoms, and any adverse events.

Efficacy of iPSC-Derived Motor Neuron Cells (XS228) in Subacute Spinal Cord Injury: A Phase II Randomized Controlled Trial

Purpose: This clinical trial is studying an investigational cell therapy called XS228-a lab-made stem cell product designed to help repair damaged nerves in the spinal cord. The goal is to see if XS228 is safe and can improve movement, sensation, and function in people with recent spinal cord injuries. Study Treatment: XS228 contains specialized nerve-supporting cells derived from human stem cells. These cells are injected into the spinal fluid (intrathecal administration) in a single dose. Who Can Join? Adults aged 18-65 with a spinal cord injury (thoracic or lumbar level) that occurred 2-12 weeks before enrollment. Participants must have severe but incomplete paralysis (ASIA Impairment Scale Grade A , B or C). Study Plan: Phase II (Main Study): About 60 participants will be randomly assigned to receive either XS228 or a placebo (inactive solution) in a 2:1 ratio. Follow-up: Patients will be monitored for 1 year, with regular check-ups to assess safety, nerve function, and recovery progress. What Researchers Are Looking For: Primary Goal: Measure changes in leg and arm function using the ASIA Motor Score at 6 months. Secondary Goals: Improvement in ASIA Impairment Scale (AIS) grade (e.g., from "complete" to "incomplete" paralysis). Recovery of sensation and bladder/bowel control. Safety (monitoring for side effects like infections or immune reactions). Exploratory Tests: MRI scans and biomarker tests in spinal fluid to see if the treatment helps nerve regrowth. Why This Study Matters: If successful, XS228 could become the first stem cell therapy to promote meaningful recovery in spinal cord injury patients. Currently, no treatments exist to repair nerve damage-this trial aims to change that.

Clinical Follow-up Study of Rituximab in the Treatment of Nephrotic Syndrome in Children

This was a retrospective study. Children who were diagnosed with refractory nephrotic syndrome and treated with rituximab (RTX) and followed up for ≥1 year in the Department of Pediatrics, the First Affiliated Hospital of Xiamen University from March 2020 to March 2026 were enrolled. Personal information, past medical history, clinical examination data and follow-up data before and after the use of RTX were extracted from the medical record system. (1) The median relapse-free survival, the number of relapses and the adverse reactions of RTX were compared before and after RTX treatment, and the clinical efficacy and safety of RTX were evaluated. (2) By comparing the annual relapse frequency, reduction and withdrawal of steroids and immunosuppressive agents, B cell reconstitution and adverse drug reactions between prophylactic RTX and post-relapse RTX maintenance regimens; (3) Multivariate analysis of risk factors for recurrence of nephropathy after RTX treatment. (4) growth indicators monitoring patient evaluation and RTX medical economic benefit analysis.

PyloPlus Urea Breath Test System Post Therapy Efficacy Confirmation Study

This is a multi-center, non-randomized, open label study. Subjects will be enrolled if they are deemed eligible given the inclusion criteria. Subjects who meet all inclusion criteria and none of the exclusion criteria will be entered into the study. Subjects will be exposed to non-radioactive 13C-Urea with citric acid, and may submit a stool sample or undergo endoscopy for Rapid Urease Test and Histology samples. Center(s) will house a PyloPlus UBT Analyzer to document results. PyloPlus Analyzer results shall remain blinded to the investigator and treating physician. No patient management decisions should be made based on the investigational PyloPlus UBT System. Treating physician will either prescribe a H. pylori Stool Antigen Test through P4 Diagnostics, along with another Urea Breath Test using Breath ID, or patient will undergo Endoscopy to provide a composite reference method consisting of Rapid Urease Test and Histology. These will act as the comparators to the PyloPlus Urea Breath Test System.
