Description of intervention(s) / exposure
Treatment: Other - CSL362

Experimental: CSL362 - See Intervention Description


Treatment: Other: CSL362
CSL362 is humanized monoclonal antibody that targets the alpha chain of the interleukin 3 receptor (IL3Ra; also known as CD123) and is optimised for enhanced activation of antibody-dependent cell-mediated cytotoxicity (ADCC) via natural killer cells.

CSL362 is a sterile solution for injection and will be administered by intravenous infusion to subjects in sequential, escalating dose level cohorts, at doses up to 12.0 mg/kg. CSL362 will be administered every 14 days for a total of 6 infusions per subject. The 6 infusions for each individual subject will contain the same dose of CSL362.
