Brief 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.

Detailed 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.

GroupInterventionDescription
Group 1 - 20 mgOligonucleotides, PhosphorothioateFour volunteers will be enrolled (no more than one per day and only after verifying that the preceding volunteer did not show any significant adverse effects) who will be administered the initial dose level (1 x 20 mg of IMT504).
Group 3 - 100 mgOligonucleotides, PhosphorothioateIf no toxicity is detected and there is good tolerance, another 4 patients will be enrolled (no more than one per day and only after verifying that the preceding one did not show significant adverse effects) who will receive treatment with the next dose level (5 x 20 mg of IMT504, one application per day for 5 consecutive days).
Group 2 - 60 mgOligonucleotides, PhosphorothioateIf no toxicity is detected and there is good tolerance, another 4 patients will be enrolled (no more than one per day and only after verifying that the preceding one did not show significant adverse effects) who will receive treatment with the next dose level (3 x 20 mg of IMT504, one application per day for 3 consecutive days).
