Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Main Inclusion Criteria:

  • Healthy male or female subjects aged ≥18 and ≤40 years of age at the time of first dosing.
  • Subjects must have a body mass index (BMI) between 18.0-25.0 kg/m² inclusive.
  • Satisfactory medical assessment with no clinically significant or relevant abnormalities as determined by medical history, physical examination, vital signs, 12-lead ECG, and clinical laboratory evaluation (haematology, biochemistry, coagulation, and urinalysis) that is reasonably likely to interfere with the subject's participation in or ability to complete the study as assessed by the Investigator.
  • Ability to provide written, personally signed, and dated informed consent to participate in the study, in accordance with the ICH Good Clinical Practice (GCP) Guideline E6 (1996) and applicable regulations, before completing any study-related procedures.
  • An understanding, ability, and willingness to fully comply with study procedures and restrictions.

Main Exclusion Criteria:

  • Current or recurrent disease (e.g., cardiovascular, haematological, neurological, endocrine, renal, liver, GI or other conditions) that could affect the action, absorption, or disposition of AST-008, or could affect clinical assessments or clinical laboratory evaluations.
  • Any history of cancer.
  • Any history (including significant and confirmed family history) of autoimmune or antibody-mediated diseases including but not limited to: systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, autoimmune hepatitis, or thrombocytopenia.
  • Has had an acute illness within two weeks prior to screening.
  • Current or relevant history of physical or psychiatric illness that may require treatment or make the subject unlikely to fully comply with the requirements of the study or complete the study, or any condition that presents undue risk from the investigational product or study procedures.
  • Any other significant disease or disorder which, in the opinion of the investigator, may either put the subject at risk because of participation in the study may influence the result of the study, or the subject's ability to participate in the study.
  • Female subjects who are pregnant or breastfeeding.
  • Subjects with abnormal findings of inguinal, axillary, or cervical lymph nodes at screening or Day -1.
  • A positive human immunodeficiency virus (HIV) antibody screen, hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibody screen.
  • Titres above reference ranges (according to local laboratory) for autoimmune antibodies: rheumatoid factor (RF), anti-nuclear antibodies (ANA), anti-neutrophil cytoplasmic antibodies (ANCA).

Treatment and study plan

AST-008

Drug

AST-008 is a toll-like receptor 9 agonist.

Primary outcomes

  1. Serious related adverse events

    Time frame: Up to 1 month after the last dose of AST-008

    To evaluate SAEs after a single subcutaneous dose of AST-008

  2. Adverse events

    Time frame: Up to 1 month after the last dose of AST-008

    To evaluate adverse events after a single subcutaneous dose of AST-008

Secondary outcomes

  1. Dose finding

    Time frame: Up to 1 month after the last dose of AST-008

    To recommend a dose and regimen for further development.

  2. Maximum plasma concentration assessment

    Time frame: Up to 1 month after the last dose of AST-008

    Measurement of the maximum observed plasma concentration (Cmax) after single doses of AST-008

  3. AUC assessment

    Time frame: Up to 1 month after the last dose of AST-008

    Measurement of the area under the curve (AUC) after single doses of AST-008

  4. Pharmacodynamics

    Time frame: Up to 1 month after the last dose of AST-008

    Measurement of type 1 cytokine concentrations as a function of time after single doses of AST-008

  5. Pharmacodynamics

    Time frame: Up to 1 month after the last dose of AST-008

    Measurement of changes in absolute number and and fraction of a panel of lymphocyte markers as a function of time after single doses of AST-008

  6. QTc interval testing

    Time frame: Up to 1 month after the last dose of AST-008

    To determine the effect of AST-008 on QTc interval
