Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 96 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2020-09-09
• Study Completion Date: 2022-02-07

Brief Summary

Originally, the study was planned to include two parts, i.e., Part A and Part B, however Part B was skipped due to changes in the overall clinical development plan. The conducted Part A was a dose-finding part to investigate the optimal dose, allowing dose adjustments upwards and downwards in younger participants. Doses tested in older participants were chosen based on acceptability of dosing in younger participants.

Detailed Description

This study was a multi-site, Phase I/II, open-label, dose-escalation study. The study included the first in human dose and dose ranging groups in healthy younger participants (aged 18 to 55 years [yrs]) and older participants (aged 56 to 85 yrs). The conducted Part A followed a dose escalation design. Discretionary dose de-escalation and refinement was also planned. Study participants with the first-in-human [FIH] immunization and any subsequent dose escalation cohorts were immunized using a sentinel dosing/subject staggering. For any dose de-escalation or dose-refinement cohorts in younger adults, i.e., cohorts with doses lower than previously tested, participants were dosed using a subject staggering process. Cohorts in older participants were optional and dependent on acceptability of dosing in younger participants. Part A consisted of a treatment phase (screening to Visit 7) and a follow-up phase (Visits 8 to 10).

Eligibility Criteria

Inclusion Criteria

• Have given informed consent by signing the informed consent form (ICF) before initiation of any trial-specific procedures.
• They must be willing and able to comply with scheduled visits, treatment schedule, laboratory tests, lifestyle restrictions (e.g., to practice social distancing and to follow good practices to reduce their chances of being infected or spreading COVID-19), and other requirements of the trial.
• They must be able to understand and follow trial-related instructions.
• For younger adult cohorts, volunteers must be aged 18 to 55 years, have a body mass index over 19 kg/m^2 and under 30 kg/m^2 (i.e., be neither underweight nor obese), and weigh at least 50 kg at Visit 0.

OR For older adult cohorts, volunteers must be aged 56 to 85 years, have a body mass index over 19 kg/m^2 and under 30 kg/m^2 (i.e., be neither underweight nor obese), and weigh at least 50 kg at Visit 0.

• They must be healthy, in the clinical judgment of the investigator, based on medical history, physical examination, 12-lead electrocardiogram (ECG), vital signs (systolic/diastolic blood pressure, pulse rate, body temperature, respiratory rate), and clinical laboratory tests (blood chemistry, hematology, and urine chemistry) at Visit 0.
• Women of childbearing potential (WOCBP) must have a negative beta-human chorionic gonadotropin urine test at Visit 0 and Visit 1. Women that are postmenopausal or permanently sterilized will be considered as not having reproductive potential.
• WOCBP must agree to practice a highly effective form of contraception during the trial, starting after Visit 0 and continuously until 60 days after receiving the last immunization. WOCBP must agree to require their male partners to use condoms during sexual contact (unless male partners are sterilized or infertile).
• WOCBP must confirm that they practiced at least one highly effective form of contraception for the 14 days prior to Visit 0.
• WOCBP must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during trial, starting after Visit 0 and continuously until 60 days after receiving the last immunization.
• Men who are sexually active with a WOCBP and have not had a vasectomy must agree to practice a highly effective form of contraception with their female partner of childbearing potential during the trial, starting after Visit 0 and continuously until 60 days after receiving the last immunization.
• Men must be willing to refrain from sperm donation, starting after Visit 0 and continuously until 60 days after receiving the last immunization.
• They must have confirmation of their health insurance coverage prior to Visit 0.
• They must agree to not be vaccinated during the trial, starting after Visit 0 and continuously until 28 days after receiving the last immunization.

Exclusion Criteria

• Have had any acute illness, as determined by the investigator, with or without fever, within 72 hours prior to the first immunization. An acute illness which is nearly resolved with only minor residual symptoms remaining is allowable if, in the opinion of the investigator, the residual symptoms will not compromise their well-being if they participate as trial participants in the trial, or that could prevent, limit, or confound the protocol-specified assessments.
• Are breastfeeding on the day of Visit 0 or who plan to breastfeed during the trial, starting after Visit 0 and continuously until at least 90 days after receiving the last immunization.
• Have a known allergy, hypersensitivity, or intolerance to the planned investigational medicinal product (IMP) including any excipients of the IMP.
• Had any medical condition or any major surgery (e.g., requiring general anesthesia) within the past 5 years which, in the opinion of the investigator, could compromise their well-being if they participate as trial participants in the trial, or that could prevent, limit, or confound the protocol-specified assessments.
• Have any surgery planned during the trial, starting after Visit 0 and continuously until at least 90 days after receiving the last immunization.
• Had any chronic use (more than 21 continuous days) of any systemic medications, including immunosuppressants or other immune-modifying drugs, within the 6 months prior to Visit 0 unless in the opinion of the investigator, the medication would not prevent, limit, or confound the protocol-specified assessments or could compromise participant safety.
