RARITAN, N.J., September 29, 2021 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced the initiation of its Phase 3 EVERGREEN study. The study will evaluate the efficacy, safety and immunogenicity of Janssen’s investigational adult vaccine against lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV), when compared with placebo in approximately 23,000 adults aged 60 years and older throughout North America and a selection of countries across Europe, Asia and the Southern Hemisphere.
The EVERGREEN study was initiated based on positive results from the Phase 2b CYPRESS study, the first large study evaluating the efficacy and safety of Janssen’s investigational RSV vaccine against RSV-associated LRTD in vaccinated adults aged 65 and older in the United States.
Efficacy and immunogenicity data from the Phase 2b CYPRESS study will be presented at the virtual IDWeek 2021 taking place from September 29 – October 3 (Abstract #1106286).
“Positive data from our first RSV vaccine efficacy study and the initiation of the Phase 3 EVERGREEN study are crucial milestones in the clinical development of our investigational RSV adult vaccine, which has the potential to safely and effectively prevent lower respiratory tract disease caused by RSV in older adults,” says Penny Heaton, M.D., Global Therapeutic Area Head, Vaccines, Janssen Research & Development, LLC. “With no vaccine or broadly-indicated antiviral treatment available, preventive solutions to address the significant morbidity and mortality in older adults caused by RSV have long been an unmet need.”
Older adults are at high risk of developing a serious infection from RSV, a highly contagious, potentially life-threatening respiratory virus affecting more than 64 million people worldwide in a typical year, across all age groups.
In September 2019, the U.S. Food and Drug Administration granted Breakthrough Therapy Designation for Janssen’s investigational RSV adult vaccine for the prevention of LRTD caused by RSV in adults aged 60 years or older. This was based on clinical data indicating the potential for substantial improvement compared to available standard of care on a clinically significant endpoint(s). In November 2020, the European Medicines Agency’s Committee for Medicinal Products for Human Use designated Janssen’s investigational RSV adult vaccine as eligible for the priority medicines (PRIME) scheme based on promising clinical data and an unmet need for a prophylactic option to prevent RSV in older adults.

About Respiratory Syncytial Virus (RSV)
Respiratory syncytial virus (RSV) is a prevalent, highly contagious respiratory virus and a leading cause of bronchitis, bronchiolitis and pneumonia, affecting more than 64 million people worldwide in a typical year. Because the symptoms of RSV can be difficult to distinguish from influenza or other respiratory infections, such as COVID-19, many who are infected with RSV remain undiagnosed.
Older adults, young children and those with underlying health conditions are most at risk. RSV disproportionately impacts adults over 60 years and high-risk adults over 18 years who are more likely to develop a lower respiratory tract infection (LRTI). Between 3-7 percent of older adults (age 60 and older) and 4-10 percent of high-risk adults (age 18 and older) experience RSV in a typical year.
With no preventive vaccine or effective antiviral treatment available, RSV remains a major global public health concern and is a substantial health and economic burden globally.
About CYPRESS (NCT03982199)
CYPRESS (NCT03982199) is a randomized, double-blind, placebo-controlled Phase 2b trial. The trial enrolled 5,782 participants (2,891 in each study arm) aged 65 years and older. The participants were randomized 1:1 prior to the RSV season to receive Janssen’s investigational RSV adult vaccine or placebo. Immunogenicity and safety assessments were performed in a subset of approximately 200 and 695 participants, respectively. Disease symptoms were collected through a questionnaire and/or by a clinician’s assessment. For further information, please see: https://clinicaltrials.gov/ct2/show/NCT03982199
About EVERGREEN (NCT04908683)
The EVERGREEN study (NCT04908683) is a randomized, double-blind, placebo-controlled Phase 3 efficacy study, which aims to confirm the efficacy of the vaccine candidate in the prevention of reverse transcription polymerase chain reaction (RT-PCR) confirmed lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) when compared to placebo in adults aged 60 years and older. The clinical trial is being conducted in countries in North America, Europe, Africa, Latin America and Asia Pacific. Trial participants will be randomized to receive either one dose of active investigational vaccine or placebo. After a year, participants who received the active vaccine will be re-randomized to receive either the active vaccine again, or placebo. Participants will be followed for at least two RSV seasons. For further information, please see: https://clinicaltrials.gov/ct2/show/NCT04908683.
