Clinical Trial Summary

Phase 1 open-label dose-escalation study to evaluate the safety and pharmacokinetics of IMT504 Phosphorothioate Oligonucleotide, an immunomodulator and tissue repair inducer, in healthy volunteers.

Description:

This is a phase 1 open-label dose-escalation study to evaluate the safety and pharmacokinetics of IMT504 Phosphorothioate Oligonucleotide, an immunomodulator and tissue repair inducer, in healthy volunteers.

A total of 12 adult volunteers of both sexes will be included, who will be progressively incorporated into 3 groups of 4 volunteers each. The first group will be administered subcutaneously with a single dose of 20 mg of IMT504. The second group will receive 3 doses (20 mg daily for 3 days) and then, if no toxicity is detected, the last group will be administered 5 daily doses of 20 mg/d.
