NCT ID: NCT05171946 Not yet recruiting - Safety Clinical Trials

Phase-I Study to Evaluate the Safety and Immunogenicity of a Prophylactic pDNA Vaccine Candidate Against COVID-19 in Healthy Adults

Start date: November 20, 2022
Phase: Phase 1
Study type: Interventional

A pneumonia of unknown cause detected in Wuhan, China, was first reported in December 2019. On 08 January 2020, the pathogen causing this outbreak was identified as a novel coronavirus 2019. The outbreak was declared a Public Health Emergency of International Concern on 30 January 2020. On 12 February 2020, the virus was officially named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and the WHO officially named the disease caused by SARS-CoV-2 as coronavirus disease 2019 (COVID-19). On 11 March 2020, the WHO upgraded the status of the COVID-19 outbreak from epidemic to pandemic, which is now spreading globally at high speed. There are currently few licensed vaccines to prevent infection with SARS-CoV-2 or COVID-19 and the duration of response is unknown. Given the rapid transmission of COVID-19 and incidence of disease on a worldwide basis, the rapid development of effective vaccines with sufficient protection and duration of response is of utmost importance. IAU has developed a thermally stable plasmid DNA (pDNA)-based vaccine candidate using a platform approach that enables the rapid development of vaccines against emerging viral diseases, including SARS-CoV-2. The pDNA vaccine developed by IAU is a synthetic, codon-optimized, encode either the full-length Spike (S) gene or S1 domain of SARS-CoV-2 as genes of interest. Here, we aim to test a synthetic, codon optimized pDNA encoding S.opt.FL as vaccine candidate against COVID-19. A key advantage of pDNA vaccine is that multiple immunization can be used without the limitations of anti-vector responses. This study is intended to investigate the safety, immunogenicity, and tolerbilty of this prophylactic vaccine against COVID-19 administered as intramuscular immunization (i.m.).

NCT ID: NCT04850950 Not yet recruiting - Chronic Hepatitis B Clinical Trials

Tenofovir Alafenamide to Prevent Perinatal Transmission of Hepatitis B

TAF-PPT
Start date: April 26, 2021
Phase: Phase 4
Study type: Interventional

To investigate the safety and efficacy of tenofovir alafenamide (orally 25 mg per day) treated in inactive chronic hepatitis B virus (HBV)-infected pregnant women with high viral load from the late pregnancy until the delivery date or postpartum 1 month.

NCT ID: NCT04596956 Not yet recruiting - Safety Clinical Trials

Safety and Efficacy of Sodium Bicarbonate Ringer Injection

Start date: October 2020
Phase: Phase 4
Study type: Interventional

Objectives 1. To observe whether sodium bicarbonate Ringer injections can reduce the incidence of postoperative complications in elderly patients undergoing abdominal surgery. 2. To observe the effects of sodium bicarbonate Ringer injections on the internal environment, such as water, electrolytes, acid-base balance, and other physiological indexes, in the perioperative period of elderly patients undergoing abdominal surgery. Research design:This study adopts a multicenter, prospective, randomized, controlled, pragmatic clinical trials (PCT) research design. Sample size:5000 cases. Indication:The experimental group is the elderly patients undergoing abdominal surgery who were administered sodium bicarbonate Ringer injections intraoperatively; the control group is the elderly patients with abdominal surgery who were administered lactated Ringer's injections intraoperatively. Observational index Preoperative baseline data collection: General patient information: basic information (age, height, and weight), preoperative diagnosis, past history, auxiliary examination results, etc. Intraoperative data collection: Perioperative vital signs information and arterial blood gas analysis results; The surgical method, operation time, and anaesthesia time; Intraoperative fluid management: The total amount of intraoperative fluids, blood transfusion volume, bleeding volume, urine volume, types and dosage of vasoactive drugs, diuretic dosage, sodium bicarbonate dosage. Postoperative index: Postoperative blood biochemical examination: liver function, renal function (urea nitrogen, creatinine), osmotic pressure, lactic acid, and blood sugar levels; Postoperative complications and treatment status Postoperative recovery: postoperative outcome, length of hospital stay, admission to ICU (duration of stay), postoperative eating time, out of bed activity time, gastrointestinal recovery time (exhaust), time for removal of various tubes (gastric tube, urinary tube, and drainage tube), etc. The observation cut-off point is the patient's discharge. If the patient is still hospitalized 30 days after the operation, the observation will be terminated. Research process 1. Elderly abdominal surgery patients who meet the inclusion criteria will be enrolled and randomly divided into two groups according to the intraoperative application of extracellular fluid supplements. The experimental group is sodium bicarbonate Ringer injection group, and the control group is sodium lactate Ringer injection. Basic preoperative information of patients will be collected. The vital signs, fluid treatment, and surgical anaesthesia will be recorded during the operation, while the recovery and postoperative complications will be recorded during postoperative visits. 2. The ability of sodium bicarbonate Ringer injections to reduce postoperative complications in elderly patients undergoing abdominal surgery will be observed. 3. The effects of sodium bicarbonate Ringer injection on the internal environment, such as water, electrolytes, acid-base balance, and other physiological indexes in elderly patients undergoing abdominal surgery will be observed and compared. 4. The safety and efficacy of sodium bicarbonate Ringer injection in elderly patients with abdominal diseases will be comprehensively assessed.
