概括
与安慰剂相比,Telitacicept在52周内显著改善了活跃的系统性红斑狼 (SLE) 患者的临床反应. 然而,它也增加了感染和注射部位反应的风险.
科学领域:
- 免疫学 免疫学 免疫学
- 类风湿病学 类风湿病学
- 临床试验 临床试验
背景情况:
- 特利塔西是一种新型的双重抑制剂,向B淋巴细胞刺激剂 (BLyS) 和APRIL细胞因子.
- 之前的2b期试验表明,在与标准治疗一起使用时,telitacicept在患有活性系统性红斑狼 (SLE) 的成年人中有效.
研究的目的:
- 在第三阶段临床试验中评估telitacicept作为活性SLE的附加治疗的疗效和安全性.

Clinical Trials
10.1K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical Trials: Overview
4.6K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
