药品与企业信息
其他名称:20-valent Pneumococcal Conjugate Vaccine (PCV20)
All participants will receive a single intramuscular dose (0.5 mL) of PCV20 (Prevnar 20®, Pfizer), administered into the deltoid muscle at baseline (Day 0). PCV20 contains purified capsular polysaccharides of 20 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 8, 9V, 10A, 11A, 12F, 14, 15B, 18C, 19A, 19F, 22F, 23F, and 33F), individually conjugated to the nontoxic diphtheria CRM197 carrier protein. The conjugation induces a T-cell dependent immune response, resulting in higher-affinity antibodies and immune memory compared to polysaccharide vaccines.

研究简介(原文)
This clinical trial aims to evaluate the effect of temporary methotrexate (MTX) discontinuation on the humoral immunogenicity of the 20-valent pneumococcal conjugate vaccine (PCV20) in adult patients with autoimmune rheumatic diseases (ARDs). Key questions: * Does suspending MTX for 2 weeks after PCV20 enhance humoral immunogenicity? * What is the impact of MTX discontinuation on functional opsonophagocytic activity (OPA) and cellular immunity? * What is the risk of disease flaring with MTX withdrawal?

这项试验目前在中国大陆没有研究中心
这种情况下,直接发"入组咨询"往往会被回复"您所在地区没有中心"。更有效的做法是申请同情用药/扩展准入(由主治医生一同提出),或询问能否到最近的境外中心参加。下面已为您切换到对应的信件版本。
