Summary:

      This was a single center, open-label, single-arm study in which approximately 28 Hepatitis A
      virus (HAV)-seronegative healthy subjects were enrolled. There was a screening period of up
      to 28 days during which subjects were screened for enrollment in the study.

      Healthy subjects received a single intramuscular (IM) dose of GamaSTAN (0.2 mL/kg), followed
      by a pharmacokinetic (PK) sampling period of 150 days (approximately 5 half-lives). The
      protective levels of anti-HAV antibodies were assessed up to 60 days after the administration
      of GamaSTAN. A PK curve was obtained during the PK sampling period.
