Development of monoclonal antibodies to prevent and treat infections from Flaviviruses

Open

The EU's Horizon Europe programme expects to make 4 awards of €9 million – €10 million each, from a total budget of €37.3 million. Applications close on 17 Feb 2027 (EU calls usually close at 17:00 Brussels time). Organisations in EU member states and Horizon Europe associated countries such as Türkiye can usually take part; the topic conditions control.

Expected outcome

This topic aims at supporting activities that are enabling or contributing to one or several expected impacts of destination “Tackling diseases and reducing disease burden”. To that end, proposals under this topic should aim to deliver results that are directed at, tailored towards and contributing to all the following expected outcomes:

• The scientific and clinical communities have a better understanding of and access to experimental monoclonal antibodies for the prevention and treatment of emerging or re-emerging viral infections, as well as for further clinical investigation.

• Candidate monoclonal antibody therapies are available to treat patients for emerging and re-emerging viral infections, increasing therapeutic options for clinical deployment in case of an epidemic or pandemic.

Scope

Infectious diseases remain a major threat to health and health security in the EU and globally. Viral disease emergence is already being accelerated by climate change, and thus a proactive approach to the development of antiviral prophylactics and therapeutics in preparedness for future infectious disease outbreaks is needed. The capacity to produce antibodies that can target new variants and rapidly increase production would serve as an essential preparedness strategy against future health threats, whether from infectious disease epidemics or pandemics.

This topic contributes to strengthening the Research and Innovation ecosystem within the EU and supports the implementation of the European Medical Countermeasures Strategy [1] .

Applicants should explicitly state in their proposal which of the following Flaviviruses is targeted and the proposed work should address only this specific Flavivirus. The proposed work should aim to advance the development of existing prophylactic and therapeutic monoclonal antibody candidates targeting exclusively one of the following Flaviviriuses:

• Dengue Virus

• Tick-borne Encephalitis Virus

• Japanese Encephalitis Virus

• West Nile Fever Virus

• Yellow Fever Virus

• Zika Virus

Proposals should focus on antibodies produced or derived from a single cell clone through recombinant expression, such as B-cell derived antibodies, hybridoma derived antibodies and nanobodies.

Proposals should thus aim to diversify and accelerate the global prophylactic and therapeutic research and development portfolio for emerging and re-emerging viral infections, and to strengthen the leading role of the EU in prophylactic and therapeutic research and development.

Proposals should address all the following research areas:

• If necessary, finalisation of the in-vitro characterisation of existing monoclonal antibody candidates with regard to target specificity, epitope recognised, and their ability to impair or inactivate viral functions.

• In-vivo tests in at least one animal model or, if available in humanised immune system animal models, to demonstrate the protective function of the monoclonal antibodies deemed sufficient for moving to first clinical trials.

• If requested by regulators as pre-requisite for clinical studies, in-vivo tests in a non-human primate model.

• Evaluation of Antibody-Dependent Enhancement (ADE) risk where scientifically relevant.

• Production of batches of the most promising antibody candidates according to the Good Manufacturing Practices (GMP) [2] .

• First in human clinical safety studies demonstrating a clear regulatory pathway for market authorisation. Attention should be paid to critical biological and social factors such as sex, age, ethnicity and disability.

Participation of third countries where viruses addressed in the proposal are endemic or where outbreaks have occurred or are ongoing is encouraged.

The participation of start-ups, micro, small and medium-sized enterprises (SMEs) [3] is encouraged…
