First human trial launches for DNA vaccine against deadly CCHF virus

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Men and women between the ages of 18 and 60 years (at the time of consent). 2. Healthy participant, according to the investigator's clinical judgment, as established by medical history, vital signs, physical examination, and laboratory assessments. 3. No clinically significant laboratory abnormalities as determined by the investigator at screening. Note: one retest of lab tests is allowed within the screening window. 4. Negative HIV 1/2 antibody/antigen test, hepatitis B surface antigen (HBsAg), and hepatitis C virus (HCV) antibody at screening. 5. Participant with a body mass index (BMI) 20-30.0 kg/m2. 6. Provide written informed consent before initiation of any study procedures. 7. A female participant is eligible for this study if she is one of the following: * of non-childbearing potential (i.e., women who have had a hysterectomy or tubal ligation or are postmenopausal, as defined by no menses in greater than or equal to 1 year) * of childbearing potential but agrees to practice highly effective contraception or abstinence (if this is the preferred and usual lifestyle of the participant) from 30 days prior to vaccination up to 3 months after last vaccination. Highly effective methods of contraception include one or more of the following: 1. male partner who is sterile (vasectomised) prior to the female study subject's entry into the study and is the sole sexual partner for the female subject; 2. hormonal (oral, intravaginal, transdermal, implantable or injectable) 3. an intrauterine hormone-releasing system (IUS) 4. an intrauterine device (IUD) with a documented failure rate of \< 1%. 8. A female participant is eligible if she is willing to abstain from donating oocyte and a male participant if he is willing to abstain from donating sperm from the screening visit up to 3 months after last vaccination. 9. A male participant who is sexually active is eligible if he is willing to use a condom from the screening visit up to 3 months after last vaccination except if the male participant is sterile (e.g. vasectomised); the unique female sexual partner is postmenopausal, is permanently sterilized (e.g. hysterectomy or tubal ligation), or use a highly effective method of contraception. 10. Able to understand and comply with planned study procedures and willing to be available for all study-required procedures, visits and calls for the duration of the study. Exclusion Criteria: 1. History of presence of pulmonary disorders (chronic obstructive pulmonary lung disease etc) or asthma (exception of allergic asthma, which is allowed). 2. History or presence of thrombocytopenia and/or bleeding disorders. 3. A positive serum pregnancy test at screening or urine pregnancy test prior to study injection, women who are planning to become pregnant during the study, or women who are breastfeeding. 4. Clinically relevant history of renal, hepatic, gastrointestinal, cardiovascular, respiratory, skin, haematological, endocrine, inflammatory, autoimmune, central nervous system or neurological diseases. 5. Use of immunosuppressive drugs as e.g. corticosteroids (excluding topical preparations and inhalers) within 3 months prior to vaccination or 6 months for chemotherapies and all along the study. 6. Vaccination within 2 weeks prior to vaccination or planning to receive a licensed vaccine before month 3 (e.g. inactivated influenza vaccine). 7. History of severe adverse reactions to vaccine administration, including anaphylaxis and related symptoms, such as urticaria, respiratory difficulty, angioedema and abdominal pain to vaccines, or history of known or suspected allergic reaction likely to be exacerbated by any component of the Investigational vaccine. 8. Participation in another investigational clinical study within four weeks before the screening visit or planned before the study completion. 9. Subjects with confirmed or suspected immunodeficiency. 10. Any condition that in the opinion of the principal investigator (PI) would jeopardize the safety or rights of a person participating in the trial or would render the person unable to comply with the protocol.
