与COVID战斗的临床试验:疫苗,测试和其他疾病

在两部分博客的第二部分中临床试验日2021we look back at a year of COVID-19 studies registered at theISRCTN registry,专注于疫苗试验,测试和对其他条件的影响。

In ourblog对于2020年临床试验,我们总结了到目前为止注册的COVID-19ISRCTN registry。One year later and there are now over170新冠肺炎studies registered. In thefirst part在这个博客中,我们回顾了platformtrials and a selection of the重新利用药物治疗从那以后开始的试验。在第二部分中,我们回顾了疫苗trials and studies looking at testing and the impact of COVID-19 on other conditions.

疫苗

Multiple vaccines have been developed for COVID-19 around the world. The vaccine developed by the牛津大学和阿斯利康大学接受了测试I/II期,,,,II/III期and第三阶段研究和结果确认该疫苗是有效的。

阿斯利康疫苗已被批准在包括英国在内的许多国家使用。针对Covid-19的大规模疫苗接种于2020年12月上旬在英国开始,可能会持续到2021年中。阿斯利康疫苗现在正在接受测试Phase II研究儿童。

其他候选疫苗正在测试中COVAC1,,,,CROWN CORONATIONand合奏2trials. There are also vaccines in development from瓦内瓦University of Queensland。所有疫苗的安全性正在由vac4covid最初在英国和ZVAC在瑞士学习。

COV-Compare研究正在比较两种剂量的阿斯利康和瓦内瓦疫苗的免疫原性,而Com-COVandcom-cov2研究正在比较疫苗的不同组合(例如,阿斯利康和辉瑞-biontech疫苗)与冠军和增强剂量,并比较剂量之间的4周和12周的间隔。

当前疫苗的保护持续时间尚不清楚,并且可能需要在9到12个月的时间内进一步加强剂量,这可能与季节性流感疫苗接种相吻合。在单独任命下交付Covid-19和流感疫苗将引起重大的后勤挑战,因此ComFluCOVtrial is determining the safety and immune response when both vaccines are given in different arms at the same appointment.

Testing

事实证明,测试是包含病毒传播的关键。这结果of theCoV-19POCstudy showed that a new point-of-care test for COVID-19 provides results more quickly and could lead to improved infection control measures and patient flow compared with centralised laboratory PCR testing.

In England and Wales infection rates in care homes have been as high as 80% and mortality rates as high as 30-50%. The维瓦尔第研究正在对护理人员和居民进行重复测试(抗原和抗体)以及CONTACTfeasibility study is looking at whether wearable digital devices can help improve contact tracing in care homes.

现在,由于无症状的案件,大量的接触,弱势群体的存在以及向儿童和员工的家庭接触传播的潜力,现在已经在英国重新开放了包含该病毒的英国,构成了特殊的挑战。在里面CoMMinSstudy researchers are mapping COVID-19 infection in participating schools with saliva tests, environmental swabbing and analysis of wastewater.

对其他条件的影响

ukoss研究收集了有关孕妇在英国与COVID-19的医院的信息结果showed that大多数人的结果良好,对婴儿的传播并不常见。但是,作者还得出结论,接纳感染的黑人或少数族裔群体中,大部分妇女需要紧急调查。

研究还研究了对COVID-19和/或疫苗接种的免疫反应。chronic health conditionsand免疫功能低下的患者这样的癌症andinflammatory bowel disease (IBD)treated with immunosuppressive or biologic drugs.

在去年,我们还发布了博客heart diseaseand COVID-19, the大脑并发症of COVID-19, and digital self-management for people living with癌症during the pandemic.

这take-home message

ISRCTN registry继续通过优先级提示与COVID相关研究的注册和报告,继续支持COVID-19的全球研究。所有注册研究均可通过WHO的全球提供International Clinical Trials Registry Platform(ICTRP),所有英国的研究都出现在Be Part of Research
