About
This first-in-human clinical trial, is a dose escalation multi-center trial designed to assess the safety, tolerability, and immunogenicity of the vaccine component, BNT165b1, an ribonucleic acid (RNA)-lipid nanoparticle (LNP) encoding for part of the Plasmodium falciparum circumsporozoite protein (PfCSP).
BNT165b1 will be evaluated at three dose levels (DLs) to select a safe and tolerable dose in a 3-dose schedule.
Full description
The trial will enroll participants into three cohorts by dose level who will be randomized 4:1 to BNT165b1:placebo. The trial will use a staggered dose escalation schema with sentinel participants for Dose 1 in all cohorts.

Are healthy, in the clinical judgment of the investigator based on volunteer-reported medical history data, and physical examination, 12-lead electrocardiogram (ECG), vital signs, and clinical laboratory test outcomes at Visit 0.
Agree not to enroll in another trial with an investigational medicinal product (IMP) starting from Visit 0 and until 12 weeks after receiving Dose 3.
Agree not to travel to a malaria endemic region starting from Visit 0 and until 28 days after Dose 3, as defined per CDC (Centers for Disease Control and Prevention).
Negative human immunodeficiency virus (HIV) -1 and -2 blood test result at Visit 0.

Negative hepatitis B surface antigen (HBsAg) test result at Visit 0 and negative anti Hepatitis C virus (anti-HCV) antibodies, or negative HCV polymerase chain reaction test result if the anti-HCV is positive at Visit 0.
Volunteers of childbearing potential (VOCBP) that have a negative serum beta human chorionic gonadotropin (β-HCG) pregnancy test result at Visit 0 and negative urine pregnancy test results before each IMP administration. Volunteers born female who are postmenopausal or permanently sterilized will not be considered VOBCP.
VOCBP who agree to practice a highly effective form of contraception and to require their male sexual partners to use condoms with a spermicidal agent, starting at Visit 0 and continuously until 90 days after receiving Dose 3.
VOCBP who agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during trial, starting at Visit 0 and continuously until 90 days after receiving Dose 3.
Men who are sexually active with partners of childbearing potential and who have not had a vasectomy that agree to use condoms with a spermicidal agent and to practice a highly effective form of contraception with their sexual partners born female during the trial, starting at Visit 0 and continuously until 90 days after receiving Dose 3.
Men who are willing to refrain from sperm donation, starting at Visit 0 and continuously until 90 days after receiving Dose 3.
Exclusion criteria
History of malaria infection (any species) based on volunteer-reported medical history.
Travel to a malaria endemic region starting 6 months before Visit 0 and continuously until 28 days after receiving Dose 3, as defined per CDC.
Prior residence for ≥6 months in a malaria endemic region.
Breastfeeding or intending to become pregnant starting with Visit 0 and continuously until 90 days after receiving Dose 3 or to father children starting with Visit 0 and continuously until 90 days after receiving Dose 3.
History of any serious adverse reactions to vaccines or to vaccine components such as lipids, and including history of anaphylaxis and related symptoms such as hives, respiratory difficulty, angioedema, and/or abdominal pain. (Not excluded from participation: a volunteer who had an anaphylactic adverse reaction to pertussis vaccine as a child).
Current or history of the following medical conditions:
Uncontrolled or moderate or severe respiratory diseases (e.g., asthma, chronic obstructive pulmonary disease); symptoms of asthma severity as defined in the US National Asthma Education and Prevention Program Expert Panel report, 2020 - e.g., exclude a volunteer who:
Uses a short-acting rescue inhaler (typically a beta 2 agonist) daily, or
Uses high dose inhaled corticosteroids (per American Academy of Allergy Asthma & Immunology), or
In the past year has either of the following:
Diabetes mellitus type 1 or type 2, including cases controlled with diet alone (Not excluded: history of isolated gestational diabetes).
Hypertension:
Malignancy within 5 years of screening, excluding localized basal or squamous cell cancer;
Any current or history of cardiovascular diseases, (e.g., myocarditis, pericarditis, myocardial infarction, congestive heart failure, cardiomyopathy or clinically significant arrhythmias), unless such disease is not considered relevant for participation in this trial in the investigator's judgment;
Bleeding disorder diagnosed by a doctor (e.g., factor deficiency, coagulopathy, or platelet disorder requiring special precautions);
Seizure disorder: History of seizure(s) within past 3 years. Also exclude if volunteer has used medications in order to prevent or treat seizure(s) at any time within the past 3 years.
Documented major psychiatric illness, including bipolar disorder, major depressive disorder, schizophrenia, autism, and attention deficit-hyperactivity disorder that at the discretion of the investigator could interfere with participation and follow-up as outlined by the trial.
The following diseases associated with immune dysregulation:
Previous vaccination with an approved or investigational malaria vaccine at any time or having taken part in a human malaria challenge study.
Receipt of any investigational product within 28 days before Visit 0.
Any planned non-trial vaccinations starting at Visit 0 and continuously until Visit 11 (28 days after Dose 3).
Received blood/plasma products or immunoglobulin within 120 days before Visit 1 or planned administration starting at Visit 0 and continuously until Visit 12.
Received allergy treatment with antigen injections within 28 days before first IMP administration or that are scheduled within 14 days after Visits 1, 5 and 9.
Current or planned treatment with immunosuppressive therapy, including systemic corticosteroids (if systemic corticosteroids are administered for ≥14 days at a dose of ≥20 mg/day of prednisone or equivalent) starting at Visit 0 and continuously until Visit 11 (28 days after Dose 3). Intraarticular, intrabursal, or topical (skin or eyes) corticosteroids are permitted.
Have a history of alcohol abuse or drug addiction within 1 year before Visit 0 or have a history (within the past 5 years) of substance abuse which in the opinion of the investigator, could compromise their wellbeing if they participate as participants in the trial, or that could prevent, limit, or confound the protocol-specified assessments.
Any existing condition which may affect vaccine injection and/or assessment of local reactions assessment at the injection site, e.g., tattoos, severe scars, etc.
Are vulnerable individuals as per International Council for Harmonization (ICH) E6 definition, i.e., are individuals whose willingness to volunteer in a clinical trial may be unduly influenced by the expectation, whether justified or not, of benefits associated with participation, or of a retaliatory response from senior members of a hierarchy in case of refusal to participate.
Any screening hematology and/or blood chemistry laboratory value that meets the definition of a Grade ≥2 abnormality or of Grade 1 at the investigator's discretion at Visit 0. Individuals with abnormal but not clinically significant parameters not included in the toxicity guidance may be considered eligible at the discretion of the investigator.
