Subject must agree to use an adequate method of contraception For male subjects: Subjects willing to follow approved birth control methods (a double barrier method) from signed ICF to Follow up call as judged by the Investigator(s), such as condom with spermicide, condom with diaphragm, or abstinence. Subjects should also not donate sperm during this time. For female subjects: Female subjects of childbearing potential, defined as a woman ≤ 55 years of age who has not had a partial or full hysterectomy or oophorectomy, must have a negative serum beta-human chorionic gonadotropin (β-hCG) pregnancy test at Screening and Admission. Subjects of childbearing potential must use a medically acceptable means of contraception from signed ICF to Follow up call. Subjects should also not participate in egg donation during this time. Subject must, in the opinion of the Investigator, be in good health based upon medical history, physical examination (including vital signs) and clinical laboratory tests assessed at the time of Screening. Subject is a nonsmoker or has quit smoking at least 6 months before the dose of study drug. Exclusion Criteria: Subject has a known history of hypersensitivity to cefazolin, any of its components, or any beta lactam antibiotic. Subject has active or recurring clinically significant renal, hepatic, skin, head, ears, eyes, nose, throat, respiratory, cardiovascular, gastrointestinal, endocrine/metabolic, genitourinary, neurologic, hematologic, musculoskeletal, immunologic, allergic, psychological/psychiatric, or other disease requiring medical treatment.

Subject has any history of relevant drug and/or food allergies as judged by the Investigator. Subjects who have received any IMP in a clinical research study within 5 halflives or within 30 days prior to first dose. However, in no event, shall the time between last receipt of IMP and first dose be less than 30 days. Subject has received probenecid within 4 weeks before dosing, or any other overthe-counter medication (including vitamins, herbal supplements, or dietary supplements) within 2 weeks before dosing. Subject has donated or lost 550 mL or more of blood (including plasmapheresis) within 60 days before the first dose of study drug. Subject has a positive test result for human immunodeficiency virus (HIV; 1 or 2) antibody, hepatitis B surface antigen, or hepatitis C virus antibody. Subject has any clinically significant illness within 5 days before the first dose of study drug as judged by the Investigator. Subject is a member of the professional or ancillary personnel involved in the study. Subject is deemed not suitable for entry into the study in the opinion of the Investigator. Failed facility's COVID-19 screening questions or tested positive for COVID-19 in a polymerase chain reaction (PCR) test on Study Day.
