Active clinical trials for "Monkeypox"

This study is a Phase 2 randomized, open-label, non-placebo controlled, multi-site clinical trial that will evaluate two ID regimens for MVA-BN vaccine compared to the standard SC regimen in healthy, vaccinia-naïve adults 18 to 50 years of age, inclusive, (Stage 1). In Stage 2 of the study, the standard SC regimen will be evaluated in adolescents ages 12 through 17 years, inclusive, and compared to the standard SC regimen in adults ages 18 to 50, inclusive. In Stage 2, approximately 210 healthy, vaccinia-naïve adults will be enrolled in a comparator arm (Arm 4) and will be given the standard, licensed regimen of 1x10^8 MVA-BN administered SC on Day 1 and 29 and will be combined with adults from Arm 3 (Stage 1) to be the comparator for the primary endpoint, non-inferiority testing. Approximately 210 healthy, vaccinia-naïve adolescents will be enrolled and given 1x10^8 MVA-BN administered SC on Days 1 and 29 (Arm 5). The study will have a set target enrollment of at least 25% adolescents ages 12 to 14 years to ensure that adequate numbers of younger adolescents are enrolled. The primary objectives are 1.) To determine if peak humoral immune responses in adults ages 18-50 years following an ID regimen of 2 x 10^7 TCID50 MVA-BN are non-inferior to the licensed regimen of 1 x 10^8 TCID50 MVA-BN administered SC; 2.) To determine if peak humoral immune responses in adults ages 18-50 years following an ID regimen of 1 x 10^7 TCID50 MVA-BN are non-inferior to the licensed regimen of 1 x 10^8 TCID50 MVA-BN administered SC.

The goal of this study is to assess the immune response, tolerance, and safety of the low-dose intradermal (forearm) mpox vaccine in people who are HIV+ compared to people who are HIV-, and compared to the standard-dose subcutaneous (upper arm) vaccine. The resulting data will fill knowledge gaps, inform public health practices, and address community concerns about the absence of data for low-dose intradermal mpox vaccinations in people living with HIV.

PLATINUM-CAN is a parallel collaborative trial linked with the sister trial PLATINUM led by Oxford University. PLATINUM-CAN is a multi-centre, randomized, placebo-controlled trial of Tecovirimat in non-hospitalized patients with presumptive or PCR confirmed monkeypox infection. The study will provide evidence on the efficacy and safety of Tecovirimat for laboratory-confirmed monkeypox in outpatients with monkeypox infection and determine the feasibility of conducting interventional monkeypox trials in Canada.

The purpose of this study is to examine the extent of mpox viral spread and immunologic markers in people with advanced HIV. Study findings will enhance knowledge of mpox pathogenesis in severely immunocompromised people, which can inform treatment and prevention of severe illness and deaths associated with mpox in people with advanced HIV.

The goal of this observational study is to describe possible physical and psychological sequelae after an mpox infection and to evaluate the longevity of B- and T-cell immune responses in former mpox patients and vaccine recipients. The main questions it aims to answer are: Are there any physical or pschological sequelae after mpox infection? Is the humoral and/or cellular immune response to MPOX (or vaccinia) virus) durable? Do the patients develop strong local immunity in comparison to systemic immunity? How long is the virus still detectable in semen, saliva or the ano-rectal region? Participants will answer a questionnaire, samples with blood, saliva and semen as well as anal swabs will be collected. Follow-up visits 8, 16 and 24 months after infection or vaccination are planned. A healthy control group will be recruited in our HIV-PrEP clinic.

This observational study has been designed to characterize humoral and cellular immune responses after vaccination against monkeypox (MKP) in HIV positive and negative individuals at high risk of MKP infection during the vaccination campaign in the current monkeypox outbreak.

This multidisciplinary project aim to understand the epidemiology of the monkeypox in Central African Republic through the identification of the animal reservoir, the clinical and epidemiological description of the human outbreak, through an ethnological approach around risk factors of the disease and through an ecological approach of the ecological context of emergence, and the improvement of biological diagnosis.

This study is a Phase 2 randomized, open-label, non-placebo controlled, multi-site clinical trial that will evaluate two intradermal (ID) regimens for Modified Vaccinia Ankara-Bavarian Nordic (MVA-BN) vaccine compared to the standard subcutaneous (SC) regimen in healthy, vaccinia-naïve adults 18 to 50 years of age, inclusive. At least 210 participants will be enrolled and randomized to one of three study arms. The two dose sparing strategies include one-fifth (2 x 10^7) and one-tenth (1 x 10^7) of the standard dose of MVA-BN administered ID on Day 1 and 29 (Arm 1 and 2, respectively). The comparator arm (Arm 3) will be the 2-dose standard (1 x 10^8) MVA-BN SC regimen. The study will enroll a 1:1:1 randomization allocation. Participants will not be stratified by clinical trial site, demographic characteristics or human immunodeficiency virus (HIV) infection status; however, these data will be collected during screening and enrollment. Each participant may be screened either in a separate visit in the 7 days prior to Day 1 or on Day 1. The primary hypothesis involves a two-step hierarchical process. The study will first test non-inferiority of the 2 x 10^7 ID regimen relative to 1 x 10^8 SC (standard dose regimen). If the 2 x 10^7 ID regimen is non-inferior to the standard dose regimen, hypothesis testing will proceed to test non-inferiority of the 1 x 10^7 ID regimen relative to the standard dose regimen. The primary objectives are: 1) to determine if peak humoral immune responses following an ID regimen of 2 x 10^7 50% Tissue Culture Infectious Dose (TCID50) MVA-BN are non-inferior to the licensed regimen of 1 x 10^8 MVA-BN administered SC; 2) to determine if peak humoral immune responses following an ID regimen of 1 x 10^7 TCID50 MVA-BN are non-inferior to the licensed regimen of 1 x 10^8 MVA-BN administered SC.

General objective: to measure the preparedness of pharmacists and medical interns about monkeypox Specific objectives: to evaluate the level of knowledge among pharmacists and medical interns about monkeypox treatment and nature of disease

The goal of this multicentre, observational study on mpox in infants, children and adolescents is to increase knowledge about mpox infection and its associated disease in infants, children and adolescents. This will be done through the development of a harmonized system that will allow standard collection of information on demographics, clinical symptoms, clinical course, treatments and outcomes. The study will be carried out in three potential phases: Phase 1 entails the rapid development of an online paediatric registry collecting anonymised data from routine care on infants, children and adolescents with laboratory-confirmed mpox virus infection. If warranted, the study will proceed to Phase 2, an enhanced observational study of children and adolescents with confirmed mpox virus infection, if more detailed prospective data collection would aid the public health response. There is also the potential to initiate Phase 3, comprising of nested sub-studies to investigate specific research questions in this population.
