Outcome Measures

Primary Outcomes (1)

  • Incidence of ALTB-268 Treatment-Emergent Adverse Events

    Adverse events (AEs) - severity of the AEs will be graded using the most current version of the Common Terminology Criteria for AE (CTCAE) (V5.0) 5-point scale. The relationship between AEs and the study drug will be indicated as related or not related.

    through study completion, up to day 120 of the study

Secondary Outcomes (6)

  • Pharmacokinetics of ALTB-268 AUC (PK) of sc administered ALTB-268 in healthy volunteers.

    through study completion, up to day 120 of the study

  • Pharmacokinetics of ALTB-268 Cmax

    through study completion, up to day 120 of the study

  • Pharmacokinetics of ALTB-268 tmax

    through study completion, up to day 120 of the study

  • Pharmacokinetics of ALTB-268 t1/2

    through study completion, up to day 120 of the study

  • Pharmacokinetics of ALTB-268 CL/F

    through study completion, up to day 120 of the study

  • +1 more secondary outcomes

Other Outcomes (3)

  • Pharmacodynamics of ALTB-268 Receptor Occupancy

    through study completion, up to day 120 of the study

  • Exploratory Immunophenotyping Lymphocyte subsets

    through study completion, up to day 120 of the study

  • Pharmacodynamics - change in target engagement biomarkers

    through study completion, up to day 120 of the study

  • Body mass index (BMI): 18.0 to 32.0 kg/m2, inclusive, at screening.
  • Weight: 50 kg to 110 kg, inclusive, at screening.
  • Healthy volunteers: Healthy status as defined by the absence of evidence of any clinically significant, in the opinion of the Investigator, active or chronic disease following a detailed medical and surgical history, a complete physical examination including vital signs, 12-lead ECG, hematology, blood chemistry, serology, and urinalysis

You may not qualify if:

  • Males with female partners who are pregnant, lactating, or planning to become pregnant during this study or within 90 days after dosing of study drug.
  • Use of any investigational drug or device within 30 days or five half-lives whichever is longer, of the first dose of study drug.
