GSK's RSV and Shingles Vaccine Trial Shows Promising Results

GSK plc Reports Positive Results on Co-Administration of RSV and Shingles Vaccines

GSK plc (LSE/NYSE: GSK) has recently revealed promising topline data from a significant phase 3 trial involving adults 50 years and older. This study focused on the immunogenicity, reactogenicity, and safety of AREXVY, a respiratory syncytial virus (RSV) vaccine, when administered alongside SHINGRIX, the recombinant zoster vaccine. Both vaccines utilize GSK's advanced AS01 adjuvants. The results were noteworthy and presented during a special session at a prominent European medical conference.

Phase 3 Trial Insights

The findings indicate that the co-administration of AREXVY and SHINGRIX resulted in a comparable immune response compared to when these vaccines are given separately. Importantly, the study demonstrated that this combined approach was well tolerated by participants, showing acceptable safety and reactogenicity profiles. The adverse events reported most frequently included pain at the injection site, fatigue, and myalgia in both groups, with a similar duration of these symptoms observed.

Expert Commentary

Dr. Len Friedland, Vice President of Scientific Affairs and Public Health at GSK, expressed enthusiasm about these results. He emphasized the societal benefits of promoting adult immunization, noting that many adults miss out on necessary vaccinations due to inadequate rates. The co-administration strategy proposed by GSK may alleviate the burden on healthcare systems by minimizing the number of visits required for vaccinations.

Regulatory Path and Safety Considerations

Following this trial, GSK plans to submit the results for peer-reviewed publication while also using the data in regulatory submissions to authorities, including the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA). The implications for public health are significant given the severe health risks that both RSV and shingles pose for older adults, especially as age-related decline in immune function increases susceptibility.

Understanding RSV and Shingles Risks

RSV poses a serious health threat to older adults, with significant hospitalization numbers reported annually. Each year, around 177,000 seniors in the US are hospitalized due to RSV, with a notable incidence of fatalities. On the other hand, shingles represents a painful condition resulting from the varicella-zoster virus (the same virus that causes chickenpox) and is marked by a painful rash that can have lasting impacts on quality of life.

AREXVY: A Closer Look

AREXVY is designed to prevent lower respiratory tract disease caused by RSV and has already received approvals in over 50 countries. This vaccine contains the recombinant RSV glycoprotein F stabilized in the prefusion state combined with a proprietary adjuvant, AS01E. Regulations in various regions are ongoing to expand its utilization to more vulnerable groups, particularly those aged 50 to 59 who are at heightened risk.

Indications for AREXVY

AREXVY is indicated for active immunization to prevent lower respiratory tract disease caused by RSV in two primary groups:

• Individuals aged 60 years and older.
• Individuals aged 50 to 59 who are at increased risk for developing respiratory syncytial virus-induced lower respiratory tract disease.

SHINGRIX Overview

SHINGRIX is a non-live, recombinant vaccine effective against shingles in those aged 50 and above. It contains glycoprotein E, which works in conjunction with the AS01B adjuvant system. Notably, SHINGRIX is effective even against the natural decline in immune response that occurs with aging and is recommended for immunocompromised individuals at heightened risk.

Indications for SHINGRIX

The use of SHINGRIX is approved for:

• Adults 50 years and older.
• Adults 18 years or older at risk for shingles due to known immunocompromised conditions.

Both vaccines—AREXVY and SHINGRIX—hold great promise in combatting critical health risks faced by older adults. Through continuous development and innovative study designs, GSK remains committed to advancing healthcare solutions.

Frequently Asked Questions

What was the main finding of the GSK trial?

The key finding was that co-administering AREXVY and SHINGRIX led to a non-inferior immune response compared to administering them separately, with good tolerability.

How many adults participated in the trial?

A total of 530 adults aged 50 and over were involved in the phase 3 trial.

What side effects were reported from the vaccines?

The commonly reported side effects included pain at the injection site, fatigue, and myalgia, with similar rates across both administration methods.

What is the significance of this trial?

This trial is significant as it explores a combined immunization approach, potentially reducing the need for multiple healthcare visits for older adults.

Where will the results be published?

The findings are expected to be submitted for peer-reviewed publication to reach a wider medical audience and support regulatory efforts.
