A multicenter, prospective, randomized trial of the efficacy and safety of Alflutop® in an alternating dosing regimen versus the standard one. Communication 1: Evaluation of the efficacy of the drug in different treatment regimens

Using of more convenient drug regimens is one of the ways to increase patient adherence to treatment for osteoarthritis (OA).Objective: to evaluate the efficacy of Alflutop® in an alternating dosing regimen versus its standard administration to patients with knee OA. Patients and methods. The investigation included 130 randomized patients who had Kellgren—Lawrence Grade II—IIIprimary tibiofemoral knee OA with pain intensity on walking at least 40 mm on a visual analogue scale and needed to take nonsteroidal anti-inflammatory drugs (at least 30 days in the previous 3 months). The patients were divided into two groups: 1) those who received Alflutop® 2 ml intramuscularly (IM) every other day (a total of 10 injections); 2) those who used the drug 1.0 ml IM daily for 20 days. The duration of the investigation was 14 weeks. Results and discussion. Just on days 20/21 of treatment, the patients of both groups were recorded to have statistically significant reductions in knee pain on walking (p
