Study Endpoints

Primary Endpoints

Number of participants with solicited administration site adverse events (AEs)
Day 1 to Day 7

The AEs considered are tenderness, redness, and swelling.

Number of participants with solicited systemic adverse events (AEs)
Day 1 to Day 7

The AEs considered are fever, irritability, loss of appetite and somnolence (sleepiness/drowsiness).

Number of participants with unsolicited AEs
Day 1 to Day 30

An unsolicited AE is an AE that was either not included in the list of solicited events or could be included in the list of solicited events but with an onset outside the specified period of follow-up for solicited events.

Number of Participants with Serious AEs (SAEs), Adverse Events of Special Interest (AESIs) and AEs Leading to Withdrawal
Day 1 up to trial end (Month 16)
Number of Participants with Hematological and Biochemical Laboratory Abnormalities
On Day 8 compared to Day 1 (pre-vaccination)
Number of Participants with Solicited Systemic AEs
Day 1 to Day 7

The solicited systemic AEs considered are fever, headache, fatigue (tiredness), myalgia (muscle pain), and arthralgia (joint pain).

Number of Participants with Serious Adverse Events (SAEs)
From Day 1 to Day 181 (study end)

SAE is an AE which results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or other situations that are considered serious per medical or scientific judgment.

Number of Participants with Adverse Events of Special Interest (AESIs)
From Day 1 to Day 181 (study end)
Number of Participants with AEs Leading to withdrawal from the study
From Day 1 to Day 181 (study end)
Number of Participants with any Laboratory abnormalities

Frequently asked questions about Pn-MAPS30plus

What is Pn-MAPS30plus used for?

Pn-MAPS30plus is an investigational pneumococcal vaccine being developed for the prevention of bacterial pneumonia. It is currently in Phase 1 clinical trials evaluating its safety, reactogenicity, and immune response in various age groups, including adults, toddlers, and infants.

Who makes Pn-MAPS30plus?

Pn-MAPS30plus is being developed by GSK plc, a global biopharma company listed on the London Stock Exchange under the ticker GSK. The company is conducting multiple Phase 1 trials to assess the vaccine's safety and immunogenicity across different populations.

What phase is Pn-MAPS30plus in?

Pn-MAPS30plus is currently in Phase 1 clinical development. It is an investigational vaccine and has not been approved by regulatory authorities. The ongoing trials are designed to evaluate its safety, reactogenicity, and immune response in adults, toddlers, and infants.

What clinical trials is Pn-MAPS30plus in?

Pn-MAPS30plus is being studied in four Phase 1 trials. NCT07105722 (completed, adults 50-64) and NCT07428759 (active, adults 50-64) evaluate safety and immune response in Australia. NCT07406334 (recruiting, toddlers 12-15 months) and NCT07406347 (not yet recruiting, infants) assess safety and reactogenicity in South Africa.

How does Pn-MAPS30plus work?

Pn-MAPS30plus is a monoclonal antibody-based pneumococcal vaccine designed to elicit an immune response against bacterial pneumonia. The specific molecular target has not been disclosed, but the vaccine aims to generate protective immunity against pneumococcal infection.

Is Pn-MAPS30plus the same as other pneumococcal vaccines?

Pn-MAPS30plus is a distinct investigational vaccine candidate developed by GSK. It is not identified as being the same as any other marketed pneumococcal vaccine. Its unique formulation and mechanism are under evaluation in early-stage clinical trials.
