Study Endpoints

Primary Endpoints

Number of Subjects With Solicited Local Adverse Events (AEs) After First Dose of Vaccination
During a 7-day follow-up period (i.e. on the day of vaccination and 6 subsequent days) after first dose of vaccination administered at Day 1

Assessed solicited local AEs at injection site are pain, erythema and swelling. Any erythema/swelling is scored with a diameter larger than (\>) 20 millimeters (mm).

During a 7-day follow-up period (i.e. on the day of vaccination and 6 subsequent days) after second dose of vaccination administered at Day 61

Assessed solicited general AEs solicited are: arthralgia; fatigue; fever (any temperature greater than or equal to 38.0 °C - the preferred location for measuring temperature being the oral cavity); gastrointestinal symptoms including (nausea, vomiting, diarrhea and/or abdominal pain); headache; myalgia and shivering.

Number of Subjects With Unsolicited AEs After Any Vaccination
During a 30-day follow-up period (i.e., on the day of vaccination and 29 subsequent days) after any vaccination (across doses)

An unsolicited AE is any AE reported in addition to those solicited during the clinical study. Also, any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited AE.

Number of Subjects Presenting Change From Baseline in Hematology and Biochemistry With Respect of Normal Laboratory Ranges, After First Vaccine Dose When Compared to Day 1
At 7 days after the first vaccine dose (i.e. at Day 8 versus Day 1)

Assessed hematological laboratory parameters include basophils, eosinophils, erythrocytes, hemoglobin, lymphocytes, monocytes, neutrophils, platelets, white blood cells. Biochemical laboratory parameters include alanine aminotransferase \[ALT\], aspartate aminotransferase \[AST\], creatinine, urea nitrogen and uric acid. Categories reported when comparing Day 1 (pre-vaccination dose 1=baseline) and Day 8 hematological and biochemical laboratory results are defined as follows: \<parameter\>-\<range at baseline\>-\<range at timing\> (e.g. ALT-Within-Within). Ranges level being classified as below, within or above the normal ranges.

Number of Subjects Presenting Change From Baseline in Hematology and Biochemistry With Respect of Normal Laboratory Ranges, After Second Vaccine Dose When Compared to Day 61
At 7 days after the second vaccine dose (i.e at Day 68 versus Day 61)

Assessed hematological laboratory parameters include basophils, eosinophils, erythrocytes, hemoglobin, lymphocytes, monocytes, neutrophils, platelets, white blood cells. Biochemical laboratory parameters include alanine aminotransferase \[ALT\], aspartate aminotransferase \[AST\], creatinine, urea nitrogen and uric acid. Categories reported when comparing Day 61 (pre-vaccination dose 2=baseline) and Day 68 hematological and biochemical laboratory results are defined as follows: \<parameter\>-\<range at baseline\>-\<range at timing\> (e.g. ALT-Within-Within). Ranges level being classified as below, within or above the normal ranges.

Number of Subjects With Any Grade 3 Non-serious AEs (Solicited and Unsolicited) After First Dose of Vaccination
During a 30-day follow-up period (i.e., on the day of vaccination at Day 1, and 29 subsequent days) after first vaccination

A Grade 3 AE is any AE assessed as severe, i.e. which prevents normal, everyday activities. In adults, such an AE would, for example, prevent attendance at work and would necessitate the administration of corrective therapy.

Number of Subjects With Any Grade 3 Non-serious AEs (Solicited and Unsolicited) After Second Dose of Vaccination
During a 30-day follow-up period (i.e., on the day of vaccination at Day 61, and 29 subsequent days) after second vaccination

A Grade 3 AE is any AE assessed as severe, i.e. which prevents normal, everyday activities. In adults, such an AE would, for example, prevent attendance at work and would necessitate the administration of corrective therapy.

Number of Subjects With Any Serious Adverse Events (SAEs) up to 30 Days After the Second Vaccination
From Day 1 up to 30 days after the second vaccination (Day 91)

A SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization or results in disability/incapacity.

Number of Subjects With Any Potential Immune-mediated Diseases (pIMDs) up to 30 Days After the Second Vaccination
From Day 1 up to 30 days after the second vaccination (Day 91)

pIMDs are a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune etiology

Frequently asked questions about RSV_PreF3 Vaccine adjuvanted with AS01B

What is the RSV_PreF3 Vaccine adjuvanted with AS01B?

The RSV_PreF3 Vaccine adjuvanted with AS01B is an investigational vaccine developed by GSK plc for the prevention of respiratory syncytial virus infections. It combines a prefusion-stabilized RSV F protein antigen with the AS01B adjuvant system and is being studied in older adults.

What is the RSV_PreF3 Vaccine adjuvanted with AS01B used for?

It is being developed for the prevention of respiratory syncytial virus infections. RSV is a common respiratory pathogen that can cause serious illness in older adults. The candidate vaccine is intended to protect this population by inducing an immune response against the virus.

Who makes the RSV_PreF3 Vaccine adjuvanted with AS01B?

GSK plc, which trades under the ticker GSK, is the developer of the RSV_PreF3 Vaccine adjuvanted with AS01B. The company also refers to the candidate as GSK3844766A. GSK is a global pharmaceutical company with an established vaccine portfolio.

What phase is the RSV_PreF3 Vaccine adjuvanted with AS01B in?

The RSV_PreF3 Vaccine adjuvanted with AS01B is in Phase 1 clinical development. It is an investigational vaccine and has not been approved by the FDA. The Phase 1 program has been completed, and the candidate remains in clinical development.

What clinical trials is the RSV_PreF3 Vaccine adjuvanted with AS01B in?

The candidate has been studied in one completed Phase 1 trial, NCT04090658, titled a study to test GSK's RSV candidate vaccine's safety and immune response in Japanese older adults. The trial enrolled 40 participants aged 60 years and older in Japan and was randomized, double-blind, and placebo-controlled.

Is the RSV_PreF3 Vaccine adjuvanted with AS01B the same as GSK3844766A?

Yes. The RSV_PreF3 Vaccine adjuvanted with AS01B is also known as RSV_PreF3 Vaccine (GSK3844766A) adjuvanted with AS01B. GSK3844766A is GSK's internal designation for the same candidate vaccine, so the two names refer to the same investigational asset.
