| NCT04822376 ↗ | Prophylaxis Vaccine Antibodies Ebola | Not yet recruiting | ANRS, Emerging Infectious Diseases | Phase 2 | 2021-10-17 | - Three measures are currently being implemented to control Ebola outbreaks: - Monitoring of contacts - Isolation and treatment of sick people - Vaccination of the population in high-risk areas. - In contacts with high viral exposure and therefore a high risk of incubation and rapid expression of infection, the r-VSV-ZEBOV vaccine does not provide adequate protection because vaccine antibody production is effective 6 to 10 days after administration. - Specific monoclonal antibodies (Mab) from the Regeneron and mAb114 research specialties have been shown to be effective in reducing mortality in patients with Ebola virus disease (EVD). - Their use in a single parenteral administration and good tolerability make them candidates for use in post-exposure prophylaxis (PEP) in individuals at high risk of viral exposure. - A comprehensive strategy for the protection of high-risk contacts must therefore be implemented, including the vaccine and the Mabs, to ensure both immediate and prolonged protection. Indeed, the efficacy of the vaccine is likely to be diminished when co-administered with Mabs, as both strategies share the same viral target (the GP envelope glycoprotein) and the vaccine is replicative (and therefore may be inhibited by Mabs). PROVAE aim to evaluate the effectiveness of a comprehensive strategy to prevent transmission of MVE in contacts at high risk of infection, including (i) post-exposure prophylaxis with Mabs and (ii) vaccination with r-VSV-ZEBOV. |
| NCT04990466 ↗ | Phase 2b/3 Trial of VSV-ΔG SARS-CoV-2 Vaccine (BRILIFE) Against Approved Comparator Vaccine. | Not yet recruiting | Brilife Georgia | Phase 2/Phase 3 | 2021-09-30 | IIBR-100 (VSV-ΔG) is a self-propagating live virus vaccine that contains the spike protein of the Wuhan wild-type SARS-CoV-2 virus. Preclinical and phase 1/2 trials have demonstrated no safety signals of concern and have further demonstrated immunologic response that approximates the response seen in convalescent individuals. The purpose of this phase 2b/3 trial is to document the non-inferiority of IIBR-100 vs. an already-approved vaccine for COVID-19. |

| NCT05202288 ↗ | Pilot Study Evaluating the Impact of Delay Between Administration of Inmazeb Administration and Vaccination by Ervebo on Vaccine Immune Response on Healthy Volunteers | Not yet recruiting | Agence Nationale de Sécurité Sanitaire de Guinée (ANSS) | Phase 2 | 2022-03-01 | Ebola virus disease (EVD) is emerging regularly in various African countries for various reasons: during contact with mortal remains, during an unsafe burial or following the viral dissemination around a recovered patient. However, tools to fight the spread of the disease are being made available to countries affected by MVE. A vaccine (Ervebo), developed by the Merck laboratory, demonstrated its efficacy in protecting contacts and contacts of contacts in the "Ebola That's Enough" trial and two monoclonal antibodies (Mabs) have demonstrated their efficacy in reducing mortality in patients with EVM: REGN-E3B and Mab114. The question of their use in post-exposure prophylaxis (PEP), defined as the treatment of contacts at very high risk of contracting EVD, is essential. Vaccination with Ervebo alone does not appear to be a good option for PEP, particularly because antibody synthesis is delayed, and the vaccine is likely to be inactive for 10 days after administration. Monoclonal antibodies, on the other hand, seem to be a promising avenue in this indication because of their rapid action on the inhibition of virus entry into the cell. Moreover, Ervebo vaccine and monoclonal antibodies share the same viral target. It is therefore possible that the vaccine is inhibited by the monoclonal antibodies, particularly in the case of concomitant administration. However, no data on vaccine efficacy in combination are available. The question of the interaction between the monoclonal antibody and Ervebo and the delay between the administration of these two strategies remains unresolved. The hypothesis of this trial is that Ervebo vaccine efficacy is diminished with the concomitant administration of a monoclonal antibody, especially if this administration is close (short time between Mabs and vaccination). We hypothesize that with an optimal delay between Mabs and vaccination, the immunogenicity of the vaccine combined with monoclonal antibodies could be non-inferior to the vaccine alone, thus providing optimal short and long term protection. The primary objective of this study is to compare the vaccine immune response at 24 weeks induced by Ervebo administered on the same day (D0) or at S3, S6, or S12 of Inmazeb administration, in healthy volunteers, with vaccination with Ervebo alone. The trial will have 5 arms. The control arm (vaccination alone) will serve as a comparator of vaccine response in the intervention arms. The 4 intervention arms will assess the minimum time between Mab and vaccination. |
