There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a two-arm, open label, randomized phase II clinical study. The aim is to evaluate the safety and efficacy of Cadonilimab (a PD-1/CTLA-4 bispecific antibody) combined with XELOX regimen in pMMR locally advanced rectal cancer during the perioperative period. Eligible patients will receive either Cadonilimab plus XELOX or XELOX alone for 4 cycles before and 4 cycles after surgery. The primary endpoint is the pathological complete response rate.
This is a two-arm phase II clinical study to evaluate the efficacy and safety of Cadonilimab (a PD-1/CTLA-4 bispecific antibody) in MSI-H/dMMR locally advanced colorectal cancer as the regimen of neoadjuvant treatment. Eligible patients will receive Cadonilimab monotherapy for eight cycles before surgery and part of patients may exempt from surgery.
The goal of this exploratory study is to explore the sleep and related health benefits of the study product in Chinese middle-aged & elderly population in real world settings and potentially generate hypothesis on key exploratory and other exploratory objectives. The main questions it aims to answer are: - To explore the effects of test product on sleep quality; - To understand and evaluate effects of test product on sleep pattern; - To assess the subjects' overall health status self-evaluation. etc. Participants will be asked to take study product, collect the sleep pattern parameters and report the overall health status.
The goal of this clinical trial is to compare in resectable colorectal cancer liver metastasis patients.The main question it aims to answer is whether the 3-year progression-free survival rate (PFS) of "watching and waiting" is non-inferior to adjuvant chemotherapy in postoperative ctDNA-negative resectable colorectal cancer liver metastasis patients.Participants will undergo ctDNA testing after resection of colorectal cancer liver metastasis, and will be randomly assigned to receive adjuvant chemotherapy or "watching and waiting" treatment strategy. The researchers will compare the outcomes between the two groups to see if the PFS between the two groups is similar.
The study was proposed to include 20 patients with clinical suspicion of primary aldosteronism for [18F]AlF-NOTA-pentixather PET/CT imaging and to analyze the specificity and sensitivity of [18F]AlF-NOTA-pentixather PET/CT for the diagnosis of APA by comparison with the final pathological findings.
The goal of this study is to evaluate the safety and efficacy of LX103 treatment of X-linked retinoschisis. This study will enroll subjects aged ≥ 6 years old to receive a single unilateral intravitreal (IVT) injection of LX103 to evaluate its safety and efficacy.
This clinical trial is a multicenter, randomized, double-blind, controlled phase II clinical study.
This project aims to investigate the effectiveness of existing common antidepressants and to provide new evidence for depressed children and adolescents who are not responding to their first treatment.
Rheumatoid Arthritis (RA) is a chronic inflammatory disease causing pain, stiffness, swelling and loss of joint function. This study will assess how safe and effective upadacitinib is in treating RA when compared to adalimumab in adult participants with inadequate response or intolerance to one TNF-inhibitor who are on a stable dose of methotrexate (MTX). Adverse events and change in disease activity will be assessed. Upadacitinib is an approved drug for the treatment of RA. This study is double-blinded means that neither the participants nor the study doctors will know who will be given upadacitinib and who will be given adalimumab. Study doctors put the participants in 1 of the 2 groups, called treatment arms randomly, to receive either upadacitinib or adalimumab. There is 1 in 2 chance that participants will receive adalimumab. Each group consists of 2 periods. Approximately 480 participants diagnosed with RA will be enrolled in approximately 250 sites across the world. Participants will receive the oral upadacitinib once daily and matching adalimumab placebo every other week, or the subcutaneous adalimumab every other week and matching upadacitinib placebo once daily during Period 1. Eligible participants will continue to receive same study treatment in Period 2 as assigned in Period 1 and will be followed for 30 days and 70 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
This is an open label, single-arm Phase I study to evaluate the safety, tolerability, PK and preliminary efficacy of AB-218, an oral IDH1 inhibitor, for the treatment of adult patients with advanced IDH1 mutant cholangiocarcinoma and other solid tumors who have failed at least one prior therapy in the advanced stage. The study contains a dose escalation part and a dose expansion part. In the dose escalation part, participants are enrolled sequentially into one of 3 dose levels of AB-218 (125 mg BID, 250 mg BID and 500 mg BID) following a 3+3 rule. Intensive PK sampling will be performed during the dose escalation part. Participants will be followed up for DLTs from the date of first study dose to 28 days afterwards. When all participants in the dose escalation part have completed the 28-day DLT observation period, SMC will review the available data including but not limited to safety, tolerability and PK, and then recommend the dose for the study dose expansion part. In the dose expansion part, there are 2 disease cohorts planned: cholangiocarcinoma (CCA) and other IDH1 mutant solid tumors. It is planned to enrol 30 participants in the CCA cohort and another 15 participants in other IDH1 mutant solid tumors, to assess the safety and preliminary efficacy of AB-218. Sparse PK samples will be collected to further evaluate the PK profile in the different target populations. Each participant will undergo screening up to 28 days prior to the start of the treatment period. The treatment period consists of a visit on Day 1 of every 28-day cycle and continues until any of disease progression, unacceptable toxicity, withdrawal of consent or death. An end of treatment (or early discontinuation) visit occurs 30 days (± 7 days) after the last dose of study medication, and a survival follow call every 12 weeks until death, withdrawal of informed consent, loss to follow-up (LTFU) or termination of the study by the sponsor, whichever occurs first.
