Study summary

This is a Phase I study to investigate the safety and tolerability of AZD4831 in healthy male participants, conducted at a single center. The results from this study will form the basis for decisions on future studies. Another purpose of this dose escalation study is to find out the right dose of the experimental drug to be given to study participants in future studies. Even though there were no harmful effects seen in the animals tested, investigator does not know what side effects the experimental drug might cause in humans. However, site personnel managing the study participants will be blinded to the extent possible and as long as possible to minimize any impact on data collection. Study participants will be blinded to treatment allocation.

The study will be conducted in healthy participants to avoid interference from disease processes or other drugs.

The participants will stay at the study center during the whole dosing period and until 48 hours post final dose.
