Trial Outcomes & Findings for Phase 2 Study Of VLA15, A Vaccine Candidate Against Lyme Borreliosis, In A Healthy Pediatric And Adult Study Population (NCT NCT04801420)

NCT ID: NCT04801420

Last Updated: 2025-11-12

Results Overview

Participants or their legal guardians were required to record any solicited local and systemic adverse events in the electronic diary. Solicited symptoms were pre-defined symptoms which were collected via an electronic diary. Solicited local AEs included pain, tenderness, erythema (redness), swelling and induration (hardening). Solicited systemic AEs included headache, muscle pain, joint pain, nausea, vomiting, fatigue and fever. Two-sided 95% confidence intervals were calculated according to Altman method.

PRIMARY outcome

Timeframe: From Day 1 to Day 7 after vaccination 1 at Month 0

Population: Safety Analysis Set (SAS) included all participants who entered into the study and received at least one vaccination. Participants were analyzed according to the actual treatment received. All participants reported under 'Overall Number of Participants Analyzed' contributed data to the table but may not have evaluable data for every row. Here, "Number Analyzed" signifies participants evaluable for specified rows.

Participants or their legal guardians were required to record any solicited local and systemic adverse events in the electronic diary. Solicited symptoms were pre-defined symptoms which were collected via an electronic diary. Solicited local AEs included pain, tenderness, erythema (redness), swelling and induration (hardening).

PRIMARY outcome

Timeframe: From Day 1 to Day 7 after vaccination 1, 2 or 3 at Month 0, 2 and 6 respectively

Population: Safety Analysis Set (SAS) included all participants who entered into the study and received at least one vaccination. Participants were analyzed according to the actual treatment received. All participants reported under 'Overall Number of Participants Analyzed' contributed data to the table and for each specified row.

Participants or their legal guardians were required to record any solicited local and systemic adverse events in the electronic diary. Solicited symptoms were pre-defined symptoms which were collected via an electronic diary. Solicited local AEs included pain, tenderness, erythema (redness), swelling and induration (hardening). Solicited systemic AEs included headache, muscle pain, joint pain, nausea, vomiting, fatigue and fever. Two-sided 95% confidence intervals were calculated according to Altman method.

Seroconversion Rate (SCR) for each OspA serotype specific IgG ST1 to ST6, determined by enzyme linked immunosorbent assay (ELISA). Seroconversion for ELISA was defined as: 1) For participants who were seronegative at screening: percentage of participants with a change from seronegative at screening to seropositive (i.e. antibody titer of \>=40 Units per milliliter \[U/mL\]) at a certain time point. 2) For participants who were seropositive at screening: percentage of participants with a \>= 4-fold rise in OspA IgG antibody titer from screening.
