Brief Summary

The innovative drug Treamid is planned for use in the treatment of patients with persistent lung damage and reduced exercise tolerance exertion after COVID-19 pneumonia in a multicenter, randomized, double-blind, placebo-controlled Phase IIb/III clinical study to assess the efficacy and safety of Treamid during a 28-day treatment. The primary objective of the study is to prove that in the Treamid group, the proportion of patients achieving clinically significant load tolerance is statistically significantly higher than in the placebo group. The secondary objective of the study is to evaluate the safety of Treamid and achievement of clinically significant improvements in indicators for various questionnaires and spirometry data.

Outcome Measures

Primary Outcomes (1)

• Rate of clinically significant recovery of exercise tolerance (based on the 6MWD) from baseline values compared to Placebo.

  Clinically significant recovery of exercise tolerance is considered for patients with no significant abnormalities (Distance ≥ lower limit of normal), clinically significant decrease in the Borg dyspnea score (≥1 points), in the absence of a decrease in the distance traveled from the baseline values; for patients with severe abnormalities (Distance \< lower limit of normal distance), clinically significant increase in the distance traveled by 54 or more meters with a decrease in the Borg dyspnea score (≥ 0.5 points) from the baseline values.

  Day 1- Day 29

Secondary Outcomes (7)

• Frequency of clinically significant change in lung diffusion capacity adjusted for hemoglobin (% of predicted) from baseline values compared to Placebo.

  Day 1- Day 29

• Rate of clinically significant recovery of exercise tolerance improvement using the Borg scale score at Visit 3, Visit 4, and Visit 5 from baseline values compared to Placebo.

  Day 1- Day 56

• Rate of clinically significant reduction in dyspnea by BDI/TDI scales at Visit 4 and Visit 5 from baseline values compared to Placebo.

  Day 1- Day 56

• Rate of clinically significant fatigue reduction assessed by change in MFIS fatigue score at Visit 4 and Visit 5 from baseline values compared to Placebo.

  Day 1- Day 56

• Rate of clinically significant reductions in Anxiety and Depression score assessed by HADS at Visit 4 and Visit 5 from baseline values compared to Placebo.

  Day 1- Day 56

Other Outcomes (18)

• Rate of clinically significant recovery of exercise tolerance (based on the 6MWD) in female patients from baseline values compared to Placebo.

  Day 1- Day 29

• Change in DLCO according to bodyplethysmography at Week 4 relative to baseline values.
