Filter by: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.
Monkey pox virus (MPXV), of the genus Orthopoxvirus, regularly causes epidemics in endemic areas of central and western Africa. Since January 1, 2022, cases of Monkey pox have been reported to WHO by 96 Member States in the 6 WHO regions. As of 22 August 2022, a total of 41,664 laboratory-confirmed cases and 192 probable cases, including 12 deaths, have been reported to WHO. Since May 13, 2022, a high proportion of these cases have been reported from countries where monkey pox transmission had not previously been documented. For the first time, cases and sustained chains of transmission are being reported in countries without direct or immediate epidemiological links to areas in West or Central Africa (WHO 2022). France is one of the most affected countries with 2889 cases reported as of August 22, 2022. This situation led the WHO Director General to declare, on July 23, 2022, that the monkeypox epidemic currently affecting several countries constitutes a Public Health Emergency of International Concern. To address this epidemic, the WHO has recommended Post Exposure Vaccination (PEP) and Pre Exposure Vaccination (PrEP) for at risk groups with 2nd and 3rd generation vaccines. In France, the Haute Autorité de Santé (French National Authority for Health) recommended on May 20, 2022, vaccination for PEP and on July 7, 2022, for PrEP with a 3rd generation MVA-BN vaccine (Imvanex® or Jynneos®). The European Medicines Agency (EMA) has approved the use of Imvanex® on July 22, 2022 for immunization against MPXV. The objective of the present study is to describe the clinical, biological, virological, pathophysiological and immunological aspects in the short and medium term of persons vaccinated against and infected with MPXV.
The overall purpose of this study is to evaluate whether tecovirimat is an efficient and safe antiviral in the treatment of monkeypox in adults and adolescents (14 years old and older). The primary objective is to evaluate the clinical efficacy, as assessed by time to all visible lesion(s) resolution, of tecovirimat treatment + Standard of Care (SOC) compared to placebo + SOC for patients with monkeypox. The secondary objective is to evaluate the clinical efficacy, as assessed by mortality, hospitalization, complications, duration of symptoms and virological shedding, and the safety of tecovirimat treatment + SOC compared to placebo + SOC in patients with monkeypox.
MonkeyPox Virus Infectious Disease (MPXVID) is a viral infection caused by the monkeypox virus (MPXV) which is an orthopoxvirus that is endemic in countries in West and Central Africa. The clinical course of the MPXVID is similar to smallpox (variola) but usually milder - with less severe disease symptoms seen in the West African subtype. Historically, the case fatality ratio of MPXVID ranged from 0 to 11% and fatality occurs more commonly among children. In Europe, human MPXVID only occurred as an imported disease with limited onward transmission. However, since May 2022 over 19.000 cases of MPXVID - mostly with the West African subtype - have been reported in Europe without a travel history to the endemic areas in Africa. The far large majority of patients with MPXVID in the current outbreak are gay, bisexual and other men who have sex with men (GBMSM). There is an urgent need to address essential knowledge gaps for optimal clinical care and public health management. The aim of this study is to improve our understanding of clinical, virological, and psychosocial outcomes in patients with MPXVID. To get a better understanding of associated risk factors for MPXV infection, and to measure quality of life and stigma, the investigators will also include a control population of men without proctitis and MPXVID-related symptoms at day 0. In addition, the investigators want to assess the vaccine effectiveness against MPXVID of infant smallpox vaccination given before 1974, as well as vaccine effectiveness of the modified vaccinia Ankara (MVA) smallpox vaccine, when administered as pre- or post-exposure prophylaxis in high risk contacts of MPXVD patients.
The purpose of this study is to find out if tecovirimat is a safe and effective drug to treat monkeypox (mpox) in combination with standard of care (SOC). Participants will be randomly assigned to receive oral tecovirimat plus SOC or placebo plus SOC for 14 days.
A5418 is a randomized, placebo-controlled, double-blind study to establish the efficacy of tecovirimat for the treatment of people with laboratory-confirmed or presumptive HMPXV disease.
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.
