Study summary

The IN2COVID Study is a 2-staged phase I/II double-blind, randomized, placebo-controlled trial to evaluate the efficacy and safety of AP-003 (Interferon α2b) when administered via inhalation twice daily for 10 days. Participants will have a final visit at Day 11.

A lead-in phase 1 substudy will be performed with at least 18 healthy adult male subjects to assess safety and tolerability of inhaled AP-003 compared to placebo for 10 days. Two cohorts of 9 subjects will be randomly assigned to receive two doses of inhaled AP-003 or placebo with an allocation ratio of 2:1. The first cohort will assess a dose of 2.5 MIU of inhaled AP-003. If no adverse events are observed, the second cohort will be conducted using a dose of 5 MIU of inhaled AP-003. Maximum tolerated dose will be determined in this phase 1 substudy.

After the completion of phase 1, the study will continue with a phase 2 treatment RCT in patients with COVID-19. In this phase, 150 adults with mild or moderate COVID-19 demonstrated by SARS-CoV-2 positive polymerase chain reaction (PCR) ≤ 5 days at enrollment will be randomized 1:1 (75 in each arm) to receive nebulized AP-003 or identical placebo twice daily during 10 days.
