XVR011 Phase 2 · Project

Broad-spectrum Nanobody Therapy for Neutralizing SARS-CoV-1 and SARS-CoV-2 Variants

healthPilotedTRL 6

Imagine a tiny, specialized key that can unlock and disable a virus's entry system. This project used llama-derived antibodies, which are much smaller than human ones, to reach hidden spots on the virus that normal antibodies miss. By blocking the virus from entering human cells, it stops the infection from spreading while the body's own immune system catches up.

The business problem

What needed solving

Current antibodies and vaccines often fail to protect against rapidly mutating SARS-CoV-2 variants. There is a critical need for therapies that target conserved regions of the virus to prevent viral escape.

The solution

What was built

A nanobody-Fc fusion candidate (XVR011) and a validated commercial manufacturing process for consistency lots.

Who can put this to work

Biopharmaceuticals
enterprise
Target: Drug developer

If you are a drug developer dealing with viral mutations that bypass current vaccines — this project developed XVR011 that binds to a highly conserved epitope to neutralize variants of concern. It provides a critical window of protection when the patient's immune system reacts too slowly.

Contract Manufacturing
enterprise
Target: CDMO

If you are a CDMO dealing with the need for scalable, stable protein production — this project developed a nanobody-Fc fusion optimized for manufacturability. The process was successfully transferred to a commercial manufacturer to produce consistency lots for registration.

Healthcare Providers
any
Target: Hospital network

If you are a hospital network dealing with severe lung damage in COVID-19 patients — this project developed a therapy that minimized lung damage in challenged hamsters. It offers a way to stop viral replication before severe symptoms escalate.

Frequently asked

Quick answers

What is the cost or price of the therapy?

Based on available project data, the specific price per dose or cost of the therapy is not mentioned; however, the EU contributed EUR 9,902,750 to the project.

Can this be produced at an industrial scale?

Yes, the technology was transferred to Millipore/Merck to establish the process for commercial manufacturing and consistency lots, following initial production in a 2000 liters BioPlant.

What is the IP and licensing status?

A strong intellectual property rights portfolio was established early in the pandemic, with seven IP patents filed.

What regulatory approvals have been obtained?

The project received approval from the Belgian regulators (FAHMP) and the Ethics Committee to move into Phase 1b/2 clinical trials.

What is the development timeline?

The project period ran from 2021-12-01 to 2022-11-30, focusing on moving the candidate into a global Phase 2 trial.

Consortium

Who built it

The consortium is heavily industry-driven, with a 75% industry ratio consisting of 3 industrial partners and 1 research partner across Belgium, Germany, and France. This structure, featuring a mix of a lead SME (ExeVir Bio) and large-scale partners like UCB and Millipore/Merck, indicates a strong focus on commercialization and manufacturing scale-up rather than basic research.
