Active clinical trials for "COVID-19"

Post-Covid(PoC)-patients with fatigue symptoms respond very differently to physical rehabilitation programs. While PoC-patients with psychological symptoms benefit little from physical interventions, fatigue and exercise capacity improves significantly without the presence of psychological symptoms. RCT studies on effects of psychotherapy or the combination of phsical activity with psychotherapy in PoC are not yet available. Therefore, the aim is to investigate the unimodal effects of psychotherapy and exercise therapy or the combination of both on fatigue in PoC patients with fatigue in a randomized clinical trial. Patients will be assigned to the three intervention groups (psychotherapy, physical rehabilitation, combination of both) stratified for sex, gender and BMI status. The intervention duration is 3 months with therapeutic online sessions for 50 min every 2 weeks. After another 3 months without intervention, the sustainability will evaluated. Secondarily, the investigators analyzes which patient benefits most from which therapeutic approach and seek for specific predictors of patient´s individual response.

The purpose of this clinical protocol is to learn about the safety, tolerability, and immunogenicity of new BNT162b2 RNA-based vaccine candidates targeting new variants of SARS-CoV-2 in healthy people. Substudy A: This study will evaluate the safety, tolerability, and immunogenicity of BNT162b2 (Omi XBB.1.5) given as a single 30 µg dose, in people who are 12 years of age and older, who previously received at least 3 doses of a US-authorized mRNA COVID-19 vaccine, with the most recent dose being an Omicron BA.4/BA.5-adapted bivalent vaccine received at least 150 days before the study vaccination (Visit 1). The study is about 6 months long for each participant. Participants will have at least 5 visits to the clinic. At each clinic visit a blood sample will be taken. At least 1 nasal swab will taken. Substudy B: This study will evaluate the safety, tolerability, and immunogenicity of BNT162b2 (Omi XBB.1.5) given as a single 30 µg dose, in people who are 12 years of age and older, who are COVID-19 vaccine-naïve who have had any positive SARS-CoV-2 test result >28 days before study vaccine administration. The study is about 6 months long for each participant. Participants will have at least 5 visits to the clinic. At each clinic visit a blood sample will be taken. At least 1 nasal swab will taken.

This is a multicenter, ambispective observational cohort study. The patients with corona virus disease 2019 (COVID-19) will be included in the study. The patients will be divided into 4 groups according to the treatment mode (Azvudine treatment group within 48 hours after the first positive for nucleic acid, Azvudine treatment group after 48 hours after the first positive for nucleic acid, short course of Azvudine treatment without nucleic acid turning negative, and the control group) . This study aims to analyze the efficacy and safety of Azvudine in the treatment of patients with COVID-19.

This is a phase Ib, randomized, double-blind, placebo-controlled study to evaluate safety, tolerability, efficacy and pharmacokinetics of ASC10 tablets in mild or moderate COVID-19 subjects.

The overarching goal of this study is to develop PET/MR techniques for the diagnosis of neuropsychiatric post-acute sequelae (PASC) of SARS-CoV-2. The central hypothesis is that immunological and cerebrovascular dysfunction after acute SARS-CoV-2 infections mediate neuropsychiatric PASC (NP-PASC).

The objective of this clinical trial is to test a new vaccine against SARS-CoV-2 (ARVAC-CG) in healthy adult volunteers, previously vaccinated against the SARS-CoV-2 virus. The main questions it aims to answer are: What is the safety and tolerability profile of the two-dose schedule of this new vaccine? What is the immune response after each dose of vaccine Participants will receive two doses of the study vaccine 28 days apart. They will be required to complete a total of 7 safety and immunogenicity follow-up visits over a 1-year period.

We did an multi-centre, observational cohort study in patients who had surgery in 2023. We included participants who underwent surgery after the COVID-19 to lift the lockdown in China. Patients meeting the same criteria were eligible who had been treated during the same calendar period of 2019 through 2021. The primary outcomes were the post-operative in-hospital complications. We hypothesized that the post-operative in-hospital complications during the COVID-19 to lift the lockdown period in China were different to complications for the same kind of patients during the same calendar period of the previous years.

This study is a prospective, multicenter clinical study. It is intended to discuss the efficacy of starting Azovudine treatment as early as possible for all types of patients of COVID-19, the time of remission of specific symptoms, the proportion of patients with severe diseases, oxygen and conditions, and related adverse reactions, so as to understand the efficacy and safety of Azovudine treatment in all types of COVID-19, and provide real world data support for the treatment of the majority of COVID-19 patients.

This study was conducted to observe whether COVID-19 can be transmitted through stem cell transplantation and whether COVID-19-positive donors have an effect on early hematopoietic reconstitution and immune reconstitution in the recipients.

To investigate intends to evaluate the incidence of adverse drug reactions (ADRs) in individuals who receive Evusheld in clinical practice to determine its post-marketing safety profile in Japanese.
