IGT-303

The goal of this clinical trial is to observe the safety of IGT-303 in healthy volunteers and participants with Chronic Kidney Disease. The main question it aims to answer is:
Is IGT-303 safe as a single dose or multiple dose regimen when applied under the skin (subcutaneously (SC)) or to a vein (intravenously (IV)).
Researchers will compare IGT-303 against a placebo to see if IGT-303 is safe for use.
Participants will be assigned to either IGT-303 or placebo and assessed for safety and tolerability for the duration of the study.
