New Data Show Shingrix can Provide atleast 10 Years of Protection Against Shingles in Adults Aged 50 Years and Over | Details Inside

GSK today announce positive interim results from the ZOSTER-049 extension study showing that overall Shingrix(Zoster Vaccine Recombinant, Adjuvanted) can provide at least a decade of protection against shingles (herpes zoster) after initial vaccination. 

The interim analysis data will be presented on 20th October 2022 at the IDWeek congress in Washington, DC, USA.

These results come from ZOSTER-049 (ZOE-LTFU), an extension from two phase III clinical trials ZOE-50 and ZOE-70.

From those trials, vaccine efficacy was 97% in adults 50 years and above and 91% in adults 70 years and above over a follow-up period of approximately four years. 

The ZOE-LTFU study, which follows participants from the ZOE-50 and ZOE-70 clinical trials for an additional six years, is ongoing and will continue to evaluate the longer-term efficacy, immunogenicity and safety of the vaccine.

Dr. Hemant Thacker, Consultant Internist and Cardio Metabolic Physician, Breach Candy, Jaslok, Bhatia and Reliance Hospital Said :

 “Shingles is a painful and distressing condition especially for the elderly. Despite treatment, elderly patients can suffer from severe complications and the persistent pain may cause difficulties in performing daily activities. A vaccine to reduce the incidence of this debilitating condition is the key. The results of the study released by GSK are promising. I am confident that a vaccine to prevent shingles, with long-lasting protection, will greatly benefit our growing elderly population and enhance their quality of life.”

Sabine Luik, Chief Medical Officer & SVP Global Medical Regulatory & Quality, GSK, Said : 

“We are delighted to see the continuing longevity of protection from our shingles vaccine. The findings from ZOE-LTFU demonstrate that it can provide a decade of protection against the pain, debilitating impact and potentially severe complications that shingles can cause in people aged 50 and over. These data significantly add to, and complement, the existing body of evidence demonstrating the long-term benefit of the vaccine,and we look forward to seeing additional results from this ongoing study.” 

Sridhar Venkatesh, Vice President & Managing Director at GSK India Said :

“Adult immunization is integral to maintain the wellbeing and quality of life of India’s growing elderly population, and to ensure healthy ageing accompanies the gains in longevity we have made as a nation. Diseases such as influenza, pneumococcal pneumonia and shingles, can be prevented by safe and effective vaccines. The encouraging results from the ZOE-LTFU trials demonstrate the long-lasting efficacy of Shingrix. Shingrix will be an important addition to our adult vaccination portfolio in India and help address an unmet preventive health need.”

Shingles is cause by the reactivation of the varicella zoster virus (VZV), the same virus that causes chicken pox.

As people age, the immune system loses the ability to mount a strong and effective immune response, increasing the risk of developing shingles.

The disease can cause unbearable pain and, in some cases, intense pain continues after the shingles rash fades, that nerve pain (called post-herpetic neuralgia [PHN]) can last for months or even years.

The Recombinant Zoster Vaccine (RZV) is the first approved shingles vaccine to combine a non-live antigen with GSK’s adjuvant and may help overcome the natural age-related decline in immunity that contributes to the challenge of protecting adults aged 50 years and above from this disease.

About ZOSTER-049

ZOSTER-049 is an open-label, long-term follow-up (LTFU) study from two pivotal phase III randomised clinical trials (ZOE-50, ZOE-70).

The study is evaluating the efficacy, safety and immunogenicity for six additional years after completion of the ZOE-50 and ZOE-70 studies. In the interim analysis conducted over the >4 years of long-term follow-up, representing up to 10 years since immunisation (mean: from 5.6 (±0.3) to 9.6 (±0.3) years post-vaccination), vaccine efficacy was 81.6%.

From 1 month post-second dose in those initial studies up to year 10 post-vaccination (mean: 9.6 (±0.3) years post-vaccination), vaccine efficacy was 89.0%.

The safety profile observed in this extension study is consistent with the established safety profile of the vaccine. No new safety concerns were identified.

The incidence of serious adverse events was consistent with the age of the study population.

No deaths or other Safety Adverse Events (SAE) considered related to vaccination were reported.

Five cases of HZ-related complications (PHN – 3 cases and HZ disseminated disease – 2 cases) were reported.

A total of 7,413 participants were enrolled in the study’s Safety cohort.

The participants were 60.7% female and 39.3% male.

Participants were 76.0% White-Caucasian/European heritage, 18.7% Asian and 5.3% Other.

ZOSTER-049 is being conducted in 18 countries/regions including Australia, Brazil, Canada, Czech Republic, Estonia, Finland, France, Germany, Hong Kong, Italy, Japan, Republic of Korea, Mexico, Spain, Sweden, Taiwan, the United Kingdom and the United States.

About Shingles

Shingles typically presents as a rash, with painful blisters across the chest, abdomen or face.v The pain is often described as aching, burning, stabbing or shock-like.

Following the rash, a person can also experience post-herpetic neuralgia (PHN) pain lasting from at least three months up to several years from the onset of rash.

PHN is the most common complication of shingles, occurring in 5-25% of all shingles cases, depending on the patients’ age.

About Shingrix

Shingrix[Herpes Zoster vaccine (recombinant, AS01B adjuvanted)] is a non-live, recombinant subunit vaccine which combines a recombinant antigen, glycoprotein E and the adjuvant system, AS01B.

In the EU, RZV is indicated for the prevention of shingles (herpes zoster) and, in some markets, for post-herpetic neuralgia (PHN), in adults 50 years of age and above. Full EU prescribing information is available here.

In several countries, including the European Economic Area (EEA), the vaccine is also approved for adults aged 18 or above who are at increased risk of shingles.

It is the only shingles vaccine approve for this at-risk patient population.

In the US, RZV is licensed for prevention of HZ (shingles) in adults aged 50 years and above, and in adults aged 18 years and above who are or will be at increased risk of HZ due to immunodeficiency or immunosuppression cause by known disease or therapy.

It is not indicated for prevention of primary varicella infection (chickenpox). Full US prescribing information is available at us.gsk.com or US Prescribing Information for RZV.

Important Safety information

The following is based on the EU and UK Prescribing Information for RZV.

Please consult the full Prescribing Information for all the labelled safety information.

  • RZVis contraindicated in anyone who is hypersensitive to the active substances or to any of the excipients of RZV.
  • As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of an anaphylactic event following the administration of the vaccine.
  • RZV should be given with caution to individuals with thrombocytopenia or any coagulation disorder since bleeding may occur following intramuscular administration to these subjects.
  • In a post marketing observational study, an increased risk of Guillain-Barré syndrome was observed during the 42 days following vaccination with RZV.
  • Syncope (fainting) can be associated with the administration of vaccines, including RZV. Procedures should be in place to avoid falling injury and to restore cerebral perfusion following syncope.
  • In adults aged 50 years and above, the most frequently reported adverse reactions were pain at the injection site, myalgia, fatigue and headache. Most of these reactions were not long-lasting.
  • In adults ≥ 18 years of age who are immunodeficient or immunosuppressed due to disease or therapy, the safety profile was consistent with that observed in adults 50 years and above.
  • There are no safety, immunogenicity or efficacy data to support replacing a dose of RZV with a dose of another HZ vaccine. There are limited data to support the use of RZV in individuals with a history of HZ. Healthcare professionals therefore need to weigh the benefits and risks of HZ vaccination on an individual basis.
  • There are no data from the use of RZV in pregnant women. As a precautionary measure, it is preferable to avoid the use of RZV during pregnancy.
  • The effect on breast-fed infants of administration of Shingrix to their mothers has not been studied. It is unknown whether RZV is excreted in human milk.
  • As with any vaccine, a protective immune response may not be elicited in all vaccines.
