NCT ID: NCT05976100 Completed - Smallpox Clinical Trials

Study of the Safety, Tolerability, Pharmacokinetics of NIOCH-14 in Volunteers Aged 18-50 Years

Start date: September 4, 2020
Phase: Phase 1
Study type: Interventional

The Aim: To study safety, tolerability and pharmacokinetics of NIOCH-14 when administered orally using a set of clinical and laboratory-instrumental methods. The research tasks are to: - to assess the safety and tolerability of different single doses of the drug; - to assess the safety and tolerability of different repeated doses of the drug; - to study pharmacokinetics of single and repeated administration of the drug; - to assess the data on safety and tolerability to select the optimal drug dosing schedule to resolve the issue of conducting phase II clinical trial in an expanded cohort of volunteers.

NCT ID: NCT05935917 Completed - Smallpox Clinical Trials

Study Evaluating the Bioequivalence of Brincidofovir Form H and Form II Tablets in Healthy Adults

BCV-001
Start date: May 30, 2023
Phase: Phase 1
Study type: Interventional

The goal of this clinical trial is to evaluate whether both Form H and Form II, 100mg brincidofovir tablets are bioequivalent, when given under fasting conditions in healthy adults. Participants will be randomized to each receive one tablet of Form H and one tablet of Form II,14 days apart and undergo pharmacokinetic testing pre-dose and post-dose to evaluate safety. This is an open-label, single-dose, randomized, two-period, crossover study.

NCT ID: NCT05846243 Completed - Smallpox Clinical Trials

Study on Immunogenicity, Reactogenicity and Safety of the VACΔ6 Vaccine in Volunteers Aged 18-60 Years

Start date: October 1, 2021
Phase: Phase 2/Phase 3
Study type: Interventional

The Aim: Study immunogenicity, confirm the safety and tolerability of different schedules of vaccination with "live cell-based vaccine against smallpox and other orthopoxvirus infections (VAC∆6 vaccine) based on vaccinia virus" using a complex of clinical and laboratory-instrumental techniques. The research tasks are to: 1. To study the immunological activity of a single VAC∆6 vaccine dose of 1x10⁷ plaque-forming units (PFU). 2. To study the immunological activity of two VAC∆6 vaccine doses (given 28 days apart) of 1x10⁶ PFU. 3. Assess the safety of different VAC∆6 vaccination schedules using a set of clinical and laboratory-instrumental techniques (thermometry, measurement of blood pressure, heart and lung auscultation, ECG, common blood and urine tests, biochemical, immunological and virological studies). 4. Assess the reactogenicity of different VAC∆6 vaccination schedules (number of local and systemic reactions, the percentage of those vaccinated with systemic and local reactions of various severity degrees). 5. To identify VAC∆6 vaccine-associated adverse events. 6. Study cell-mediated immunity induced by different VAC∆6 vaccination schedules. 7. Determine the presence of the virus in specific skin formations (crusts, pustules), saliva, blood and urine. 8. Evaluate the protective efficacy of one and two doses of the studied VAC∆6 vaccine.

NCT ID: NCT05762523 Completed - Smallpox Clinical Trials

Safety and Tolerability Study of the VAC∆6 Vaccine in Volunteers Aged 18-40 Years

Start date: May 18, 2019
Phase: Phase 1
Study type: Interventional

The aim of the clinical study is to study the safety and tolerability of the live cell-based vaccine against smallpox and other orthopoxvirus infections (VAC∆6 vaccine) based on vaccinia virus, in intracutaneous administration. The research tasks are to: - evaluate the safety of various schemes for the use of the VAC∆6 vaccine using a set of clinical and laboratory-instrumental methods (thermometry, blood pressure registration, auscultation of the heart and lungs, electrocardiography (ECG), complete blood count and common urine test, biochemical, immunological, and virological studies); - evaluate the reactogenicity of various schemes for the use of the VAC∆6 vaccine (taking into account the number of local and systemic reactions, the percentage of those vaccinated with various degrees of manifestation of systemic and local reactions); - evaluate the possibility of virus shedding into the environment by volunteers; - evaluate the immunological efficacy of various vaccine administration schemes; - identify the development of undesirable reactions to the administration of the vaccine; - evaluate the cellular immune response to the introduction of various schemes for the use of the vaccine; - evaluate preliminary efficacy data in order to select an optimal scheme for the administration of the vaccine to make a decision on conducting Phase II clinical trials in an extended group of volunteers.

NCT ID: NCT05745987 Not yet recruiting - Monkeypox Clinical Trials

Smallpox Vaccine for Mpox Post-Exposure Prophylaxis: A Cluster RCT

SMART
Start date: September 1, 2024
Phase: Phase 4
Study type: Interventional

A cluster randomized controlled trial to determine if smallpox vaccine reduces secondary cases and symptom severity in persons exposed to mpox.

NCT ID: NCT05513313 Not yet recruiting - Myopericarditis Clinical Trials

Assessment of Myocarditis After Replication-Deficient Smallpox Immunization

PAMARDSI
Start date: March 2029
Phase:
Study type: Observational

This is a prospective observational phase IV study of a novel, replication-deficient smallpox vaccine that has been recently been approved by FDA. The purpose of this study is to determine if there are any abnormalities detected by electrocardiographic testing and/or blood tests within 35 days of receiving the second dose of smallpox vaccine either alone or co-administered with other vaccines that may/may not be suggestive of myopericarditis.
