A new study testing the safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of the experimental treatment STAR-0215 for hereditary angioedema (HAE) is now recruiting participants.
The phase 1a, single-center, randomized, double-blind, placebo-controlled, single-ascending dose, first-in-human study aims to recruit 24 healthy volunteers, aged 18 to 60 years, at Spaulding Clinical Research in West Bend, Wisconsin.
Participants will be randomized to receive 1 of 3 doses of STAR-0215 (100 mg, 300 mg, or 600 mg) or a placebo.

The primary outcome measure of the trial is the number of participants experiencing treatment-emergent adverse events. Secondary outcome measures are the serum concentration of STAR-0215, plasma levels of cleaved high-molecular-weight kininogen, and the number of participants with antidrug antibodies against STAR-0215.

STAR-0215 is a monoclonal antibody that inhibits plasma kallikrein to prevent HAE attacks. Experiments in cynomolgus monkeys have shown that the subcutaneous administration of STAR-0215 led to a rapid inhibition of plasma kallikrein and rapid and sustained cleavage of high-molecular-weight kininogen.
The trial is expected to be completed in June 2023, with preliminary results being available by the end of this year.
