Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single intravenous infusion or subcutaneous injection of sterile solution for injection containing CSL346. Cohort A1: 0.1 mg/kg CSL346 or placebo; Cohort A2: 0.3 mg/kg CSL346 or placebo; Cohort A3: 1.0 mg/kg CSL346 or placebo; Cohort A4: 3 mg/kg CSL346 or placebo; Cohort A5: 10 mg/kg CSL346 or placebo; Cohort A6: (Optional) Additional dose, may be tested provided the dose is not expected to exceed predicted serum CSL346 Cmax of 3605 µg/mL and AUC0-168 of 297500 µg hr/mL
Cohort B1 through B4: Part B procedures will mirror Part A, but without the use of a sentinel group. Up to 4 dose levels of CSL346 will be studied in a total of approximately 32 subjects.
Cohorts C1-C2: In Part C of the study, the doses to be administered will be equivalent to doses previously administered by IV infusion. single ascending-doses of CSL346 will be administered by subcutaneous injection or infusion in up to 2 cohorts of healthy, adult, Caucasian subjects. SC administration will be evaluated at two dose levels: 'low dose' and 'high dose.' The Sponsor, in consultation with the SRC, will decide if sentinel subjects should be included in Part C.

Summary
Brief summary
The purpose of this study is to characterize the safety and tolerability of single ascending doses of CSL346 following intravenous (IV) administration in healthy subjects. This is a 3-part first-in-human (FIH) study. Part A is a randomized, double-blind, placebo-controlled, single ascending intravenous (IV) dose protocol to be implemented in healthy Caucasian subjects. Part B is a single ascending IV dose escalation protocol which will test selected doses from Part A in healthy Japanese subjects. Part C is a single ascending dose escalation protocol which will test the subcutaneous (SC) administration of selected doses in Caucasian, and, if needed, Japanese subjects.
