Clinical Trial Summary

This trial has two parts. Part A and Part B. Due to changes in the overall clinical development plan, Part B will no longer be conducted. The objectives originally described for Part B have been implemented in the ongoing development via a pivotal Phase I/II/III trial BNT162-02/C4591001 (ClinicalTrials.gov NCT: 04368728). Part A is for dose ranging of four different vaccines (BNT162a1, BNT162b1, BNT162b2, and BNT162c2) which will be undertaken with dose escalation and de-escalation plus the evaluation of interim dose levels. It also includes dose ranging in older participants. The vaccines BNT162a1, BNT162b1, BNT162b2, and BNT162c2 will be administered using a Prime/Boost (P/B) regimen. The vaccine BNT162c2 will also be administered using a Single dose (SD) regimen. Three additional cohorts aged from 18 to 85 years receiving BNT162b2 only. BNT162b2 has entered a Phase II/III evaluation of efficacy, with the intent to support an application for marketing authorization. The dosing regimen under investigation is two BNT162b2 doses given ~21 d apart.

Eligibility

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 (BMI) over 19 kg/m^2 and under 30 kg/m^2, and weigh at least 50 kg at Visit 0. OR For older adult cohorts, volunteers must be aged 56 to 85 years, have a BMI over 19 kg/m^2 and under 30 kg/m^2, and weigh at least 50 kg at Visit 0. OR For the immunocompromised adult cohort (Cohort 13), volunteers must be aged 18 to 85 years, have a BMI over 19 kg/m^2 and under 30 kg/m^2, 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. Note: Healthy volunteers with pre-existing stable disease, defined as disease not requiring significant change in therapy or hospitalization for worsening disease during the 6 weeks before enrollment, can be included. OR For the immunocompromised cohort (Cohort 13); volunteers who have previously received solid organ transplant, or peripheral blood stem cell transplantation =6 months after transplantation, or individuals with human immunodeficiency virus (HIV) infection with a CD4+ T-cell count of =200 x 10^6 /L at Visit 0. Individuals with lower T-cell counts will be excluded from the trial on the basis that this represents a significant medical complication. In the clinical judgment of the investigator, volunteers must be immunocompromised but otherwise healthy. After consultation with the Medical Monitor, this may include individuals receiving immunosuppressant therapy due to another confounding disease at least 2 weeks prior to enrollment and/or at least 6 weeks following immunization with BNT162b2, and/or individuals with immunosuppressive treatment of an autoimmune disease if the disease is stable.
• 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 practice 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:

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 subjects 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 subjects 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 immunosuppressant's or other immune-modifying drugs (except for Cohort 13), 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 subject safety. Note: Healthy volunteers with pre-existing stable disease, defined as disease not requiring significant change in therapy or hospitalization for worsening disease during the 6 weeks before enrollment, can be included.
• Had any vaccination within the 28 days prior to Visit 0.
• Had administration of any immunoglobulins and/or any blood products within the 3 months prior to Visit 0.
• Had administration of another investigational medicinal product including vaccines within 60 days or 5 half-lives (whichever is longer), prior to Visit 0.

• Have a history (within the past 5 years) of substance abuse or known medical, psychological, or social conditions which, in the opinion of the investigator, could compromise their well-being if they participate as trial subjects in the trial, or that could prevent, limit, or confound the protocol-specified assessments.
• Have a history of hypersensitivity or serious reactions to previous vaccinations.
• Have a history of Guillain-Barré Syndrome within 6 weeks following a previous vaccination.
• Have a history of narcolepsy.
