This will be the first-in-human (FIH) study with the oral formulation of CXA-10. The main purpose of this trial is to demonstrate the safety, tolerability and pharmacokinetics (PK) of CXA-10 and its metabolite(s) administered as single ascending oral doses to healthy volunteers (Part A). The effects of food on the PK of CXA-10 will also be investigated (Part B).
