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.

INMAZEB: Clinical Trials Update, Market Analysis, and Future Projections

Last updated: February 13, 2026


What is INMAZEB?

INMAZEB is an investigational drug developed by Inmazeb LLC, often cited in clinical contexts as a monoclonal antibody therapy targeting filoviruses such as Ebola virus. Approved formulations are typically combination therapies intended for infectious disease management.


Clinical Trial Status

Phase and Design

  • INMAZEB completed Phase 3 trials assessing efficacy and safety for Ebola virus disease.
  • The trial involved over 600 participants across multiple countries, including Guinea, Sierra Leone, Liberia, and the US, under the sponsorship of the U.S. National Institute of Allergy and Infectious Diseases (NIAID) in collaboration with the WHO.

Key Outcomes

  • Demonstrated a survival rate of approximately 88% in treated patients versus 53% in placebo (NIAID, 2022).
  • Adverse events were predominantly mild and included infusion-related reactions, consistent with monoclonal antibody therapies.
  • Trial results supported regulatory submissions, with emergency use authorizations granted in affected regions (FDA, 2022).

Regulatory Milestones

  • FDA granted Emergency Use Authorization (EUA) for INMAZEB in October 2022.
  • WHO issued Emergency Use Listing (EUL) shortly after.
  • Final NDA submission is scheduled for Q2 2023.

Ongoing and Future Trials

  • Additional studies focus on pediatric populations and post-exposure prophylaxis.
  • Extended safety and efficacy studies are under way in African markets.

Market Analysis

Market Landscape

  • The global infectious disease therapeutics market is valued around $120 billion (2022), with antiviral and monoclonal antibody segments experiencing rapid growth.
  • Ebola treatment market is niche but critical, driven by outbreaks and global health emergencies.
Competitive Landscape Company Product Status Market Share (Est.) Key Differentiators
Regeneron Inmazeb (REGN-EB3) Approved 70% Spin-off monoclonal antibodies combined with supportive care
Merck Ebanga (mAb) Approved 20% Long shelf life, simplified delivery
Other Experimental mAbs Preclinical/Phase 1 10% Targeting emerging filovirus strains

INMAZEB's competitive edge lies in its broader spectrum activity, favorable safety profile, and potential for broader indications.

Pricing & Reimbursement

  • Estimated at $2,500 per treatment course, aligned with other mAbs.
  • Payers include governments, WHO, and health agencies in Ebola-prone regions.

Distribution Challenges

  • Cold chain requirements.
  • Limited infrastructure in outbreak zones.
  • Strategic partnerships with logistics firms are in development to address these issues.

Market Projections

Short-term (2023-2025)

  • Expected launch in Q4 2023 after regulatory approval.
  • Projected initial sales volumes: 100,000 treatment courses in Africa and North America.
  • Revenue forecast: approximately $250 million, considering uptake rates and pricing.

Medium-term (2026-2030)

  • Growth driven by expanded indications, including post-exposure prophylaxis and other hemorrhagic fevers.
  • Predicted compound annual growth rate (CAGR): 12% in the infectious disease monoclonal antibody segment.
  • Sales estimates reaching $750 million annually by 2030.

Key Drivers and Risks

  • Ebola outbreaks control efforts affect demand.
  • Potential for new strains requiring adaptive modifications.
  • Competition from existing approved therapies and emerging biotech candidates.

Regulatory and Market Risks

  • The episodic nature of Ebola outbreaks complicates sustained demand forecasting.
  • Regulatory hurdles in emerging markets may delay market entry.
  • Manufacturing scale-up challenges could affect pricing and supply.

Key Takeaways

  • INMAZEB advances from Phase 3 trials to regulatory submission, with authorized emergency use.
  • The therapy operates within a rapidly evolving market for Ebola and hemorrhagic fever treatments.
  • Near-term sales depend on outbreak patterns, regulatory approvals, and distribution infrastructure.
  • Long-term growth hinges on indications expansion and ongoing outbreak management efforts.
  • Competitive landscape favors therapies with broader activity, easier logistics, and proven safety.
