READING, England--(BUSINESS WIRE)--Sanofi (EURONEXT: SAN and NASDAQ: SNY) and the National Institute for Health and Care Research (NIHR) have today announced that the first patient has been enrolled in the Hospitalised RSV Monoclonal Antibody Prevention (HARMONIE) study. The large European interventional clinical study is investigating protection against Respiratory syncytial virus (RSV) in infants. HARMONIE is an open label trial that will evaluate the use of nirsevimab, a passive immunisation, in a broad population. RSV is the leading cause of hospitalisation in all infants worldwideⁱ and affects 90% of children before the age of two.ⁱⁱ

The study has been developed as a collaboration between NIHR, investigators, Sanofi and its clinical research organisation partner, Labcorp. More than 20,000 infants across 3 countries (United Kingdom, France, Germany) will be enrolled from August 2022 to March 2023, of which the majority (up to 12,000) will be UK infants.

The first patient visit took place at Cripps Health Centre at the University of Nottingham, United Kingdom on August 8, 2022. The study will take place across approximately 280 sites, of which around 110 are in the UK. HARMONIE is Sanofi’s first hybrid digital study, and requires only one patient visit.

Dr Simon Royal
Primary Investigator, Honorary Assistant Professor at the University of Nottingham Medical School and GP at the University of Nottingham Health Service, said:

“The HARMONIE study will expand our understanding of how well a one-off injection protects babies from RSV. RSV is a major cause of death and illness in children across the world and it is the most common reason for admission to hospital in children aged under one year in the UK. Nearly 80% of the children admitted to hospital with RSV are previously healthy and at certain times of the year, children’s wards are full of babies with disease caused by this virus.”

Professor Andrew Ustianowski,
National Specialty Lead for Infection at NIHR Clinical Research Network, said:

“This study, supported by the National Institute for Health and Care Research across over 100 sites, provides the UK with the opportunity to lead the way in a disease which impacts infants globally.

“By carrying out this widespread study, we can help discover how babies can be protected from such a common, yet potentially debilitating virus.”

Dr Bogdana Coudsy
Global Head of Medical for Vaccines at Sanofi, said:

“Given RSV is a leading cause of hospitalisation in all infants, we are excited to start this research that put the needs of participants, carers, and investigators at the heart of its development. This is an innovative study in design and execution, a model for the future, thanks to a hybrid digital design and close collaborative work.”

RSV places a significant burden on families and health services

Globally, in 2015, there were approximately 30 million cases of acute lower respiratory infections. This led to more than 3 million hospitalisations, and it was estimated that there were 60,000 in-hospital deaths of children younger than 5 years.^iii-iv In recent months, there has been a resurgence of RSV following the easing of COVID-19 public health measures.^v-vi

A peer-reviewed RAND and University of Cambridge report on the burden of RSV estimated that RSV costs the UK £80 million in healthcare costs and productivity losses each year.^vii In 2017, RSV-related direct medical costs—including hospital, outpatient and follow-up care—were estimated at €4.82 billion globally.^viii

A survey of 1,500 UK parents commissioned by Sanofi in 2021 revealed that 83% of parents said infant respiratory infections impacted their mental health, with 4 in 10 (41%) experiencing significant emotional distress.^ix

Nirsevimab is being developed by Sanofi and AstraZeneca.

About HARMONIE
Hospitalised RSV Monoclonal Antibody Prevention (HARMONIE) is a phase 3b randomised open-label study of nirsevimab in preventing hospitalisations due to respiratory syncytial virus (RSV) in infants under 12 months.

This study will include newborn babies to babies 12 months old who are in, or are approaching, their first RSV season. It will last approximately 12 months.

HARMONIE is an open label interventional study which builds on successful results in phase 2b/3 trials of nirsevimab across all infants.^x Regulatory submissions for nirsevimab are already underway.

HARMONIE has been designed and developed as a result of close collaboration between Sanofi, investigators and Labcorp, with the purpose of minimising burden on participants, caregivers and parents and as such is based around a single in person visit with entirely virtual follow up.

About Nirsevimab
Nirsevimab is an investigational long-acting antibody aiming to protect all infants from birth entering their first RSV season with a single dose.x^,xi,xii

Nirsevimab is an immunisation designed to provide direct RSV protection to all infants via an antibody to help prevent LRTI caused by RSV.

In March 2017, Sanofi and AstraZeneca announced an agreement to develop and commercialise nirsevimab. Under the terms of the agreement, AstraZeneca leads all development and manufacturing activities and Sanofi will lead commercialisation activities and record revenues. Under the terms of the global agreement, Sanofi made an upfront payment of €120m, has paid a development milestone of €30m and will pay up to a further €465m upon achievement of certain development and sales-related milestones. The two companies share all costs and profits. Revenue from the agreement is reported as Collaboration Revenue in the Company’s financial statements.

Nirsevimab has been granted regulatory designations to facilitate expedited development by several regulatory agencies around the world. These include Breakthrough Therapy Designation by The China Center for Drug Evaluation under the National Medical Products Administration; Breakthrough Therapy Designation from the US Food and Drug Administration; access granted to the European Medicines Agency (EMA) PRIority MEdicines scheme; Promising Innovative Medicine designation by the UK Medicines and Healthcare products Regulatory Agency; and named “a medicine for prioritised development” under the Project for Drug Selection to Promote New Drug Development in Pediatrics by the Japan Agency for Medical Research and Development (AMED). Nirsevimab has seen successful results in phase 2b/3 trials across all infants.^x The safety and efficacy of nirsevimab is currently being evaluated under an accelerated assessment procedure by the EMA. Nirsevimab has not been approved by any regulatory authority.
