Filter by:A observer-blind, randomized, controlled, investigator-initiated clinical trial to evaluate the safety and immunogenicity of a booster vaccination with Recombinant COVID-19 vaccine (Sf9 Cell) in a population aged 18-60 years old who have completed 3 doses vaccination with COVID-19 Vaccine (Vero Cell), Inactivated ≥ 6 months at least 6 months prior to enrolment. The study uses a non-inferiority design to compare between schedules with Recombinant COVID-19 Vaccine (Sf9 Cell) versus COVID-19 Vaccine (Vero Cell) Inactivated as the booster dose. Participants, laboratory and analysing statisticians will remain blind to treatment allocation. A total of 120 participants will be enrolled, participants will be randomized 1:1 to receive a single dose of Recombinant COVID-19 vaccine (Sf9 Cell) (test group) or COVID-19 Vaccine (Vero Cell), Inactivated.
Burn injuries were thought to be difficult to treat during the new corona virus epidemic. Our goal is to determine the risk factors that influence length of hospital stay (LOS) of burn injured patients during COVID -19 pandemic.
The study investigates whether patients with mild SARS-CoV-2 infection, who stayed at home during their infection and weren't hospitalized, have any persisting sequelae in pulmonary function. Therefore, 110 patients, aged 6-60 years, were recruited by telephone 4-12 weeks after laboratory-confirmed positive PCR and invited for a lung function testing. Every patient with abnormalities in pulmonary function was invited to a follow-up 3 months after the first appointment to assess changes in lung function values. Patients with a pre-existing lung disease and smokers within the last five years were excluded beforehand. Additionally to lung function testing we did a throat swab at each appointment to analyse via Multiplex PCR whether the patients had any other respiratory infection at the time of the pulmonary function testing.
This study will assess the safety and immunogenicity of a fourth dose (booster) of BNT162b2 when coadministered with SIIV compared to separate administration of the vaccines when given 1 month apart (SIIV followed by BNT162b2), in participants who have received 3 prior doses of 30 µg BNT162b2, with the third dose being at least 90 days before Visit 1 (Day 1). - Healthy adults 18 through 64 years of age will be randomized 1:1 to either the co-administration group, or the separate administration group - The duration of the study for each participant will be approximately 2 months - There are 3 scheduled study visits each about 1 month apart - The study will be conducted in New Zealand and Australia.
The investigated product is a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Booster Vaccine candidate optimized for the Omicron/BA.2 variant. There are currently no licensed, variant-optimized vaccines to prevent infection with SARS-CoV-2 Omicron/BA.2. Approved or authorized SARS-CoV-2 vaccines are expensive, require a stringent cold chain, and have large-scale manufacturing issues, resulting in very limited availability in low- and middle-income countries (LMICs). Given the rapid global spread of the Omicron/BA.2 variant and potential for future novel SARS-CoV-2 variants, the rapid development of an easy-to-manufacture and easy-to-distribute vaccine is of great importance. The objective of the study is to assess the tolerability, safety, and immunogenicity of different doses and routes of administration of the Alveavax-v1.2 vaccine in healthy individuals. The study aims to evaluate: - the safety and tolerability of Alveavax-v1.2 in healthy participants compared to a control booster vaccine in a dose-finding design; - the immunogenicity against SARS-CoV-2 BA.2/Omicron after a booster dose of Alveavax-v1.2; - the clinical efficacy against SARS-CoV-2 after a booster dose of Alveavax-v1.2; - and the success rate of intradermal (ID) injections.
The purpose of the study is to understand the effects and safety of PF-07817883 treatment. The study wants to know how PF-07817883 treatment lowers the level of the virus that causes COVID 19. To understand that samples are collected from adult participants who have the symptoms of COVID 19 but are not hospitalized. The study is seeking for participants who: - are 18 years of age or older at the time of entering the study. - have a positive rapid antigen test within 48 hours before entering the study. Rapid antigen test is a test done to confirm the presence of a specific virus in the body. - have onset of signs or symptoms of COVID-19 within 5 days before entering the study. - have at least 1 of the specified signs or symptoms of COVID-19 present on the day of entering the study. Around 228 participants with a confirmed case of COVID 19 are planned to be taken into the study. Participants will be randomly grouped to receive PF-07817883. Three groups will receive 100, 300, 600mg of PF-07817883 and one of the groups will receive placebo (a pill that doesn't have any medicines) orally every 12 hours for 5 days. The study is going to last up to 5 weeks. This includes the initial period of selecting participants, participants receiving the medicine or the placebo and then a 4-week follow-up period after giving the participants the last medicine. The study team will monitor how each participant is doing with the study treatment during the study.
Infections with SARS-CoV-2 result in a systemic disease with a variety of outcomes, from no symptoms to severe and diverse pathologies. Therefore, it is important to identify risk factors determining COVID-19 severity, especially if those factors might be adjusted, allowing early and effective therapeutic interventions. Zinc is a trace element essential for human health. Zinc deficiency is common in old adults, vegetarians and patients with chronic inflammatory diseases. This condition causes immune dysfunction leading to increased risk of inflammatory and infectious diseases, including acquired immune deficiency syndrome, measles, malaria, tuberculosis, and pneumonia. Besides, zinc has a direct antiviral activity against specific viruses like rhinovirus, HCV, herpes simplex virus. In this scenario, it has been shown that zinc supplementation has benefits on the recurrence and persistence of acute and chronic viral infections like common cold or HCV, HBV. Moreover, our team has recently done an observational study with 249 COVID-19 patients that showed how COVID-19 patients with lower plasma zinc content had worse prognosis, increased time of hospitalization and mortality. Therefore, the main aim of the project is to explore the therapeutic benefit of zinc supplementation for COVID-19 patients and to determine the cellular and molecular basis of the effect of Zn levels on SARS CoV-2 infections. For that purpose the investigators will run a clinical trial supplementing with zinc COVID-19 patients. Moreover, the investigators will carry out experiments to understand the association between zinc nutritional status and SARS-Cov-2 infection progression in cellular and animal models. Given the current knowledge about zinc supplementation toxicity and dosage, the investigators expect that recommendations derived from this study will be rapidly applied by physicians and public health decision makers. The results of these studies will be used as a guideline to administer zinc supplements in COVID-19 patients in order to reduce disease severity and mortality. Moreover, the experiments will clarify whether zinc supplementation as a prophylaxis strategy is useful to protect the population at risk of zinc deficiency, more than 20% worldwide. Finally, considering the new knowledge that this project will generate about the role of zinc in immune responses and viral expansion, the investigators expect that our results will help researchers and physicians to design novel strategies to boost specific immune cell subpopulations against SARS-CoV2 infection. Thus, this knowledge could be used long-term for designing medicines against SARS-CoV-2 and other viral infections.
An Investigator-initiated, Randomized, Single-Blind, Placebo-Controlled Trial to Evaluate the Efficacy of SARS-Cov-2 Post Exposure Prophylaxis and Safety of HH-120 nasal spray
This study is to evaluate the efficacy of post-exposure prevention and safety of HH-120 nasal spray in participants who are caregivers of hospitalized patients infected with SARS-CoV-2. HH-120 nasal spray are administrated 8-10 times to the participants per day until the discharge of the SARS-CoV-2 infected patients or confirmed infection of the participant, whichever occurs first.
Preliminary data support a possible molecular mimicry between SARS-CoV-2 and autologous components. This suggests the occurrence of autoimmunity during COVID-19. Consistently, autoimmunity may occur after SARS-CoV2 vaccination. The study aims to investigate the production of autoantibodies after vaccination in healtcare workers.
