- Registration Number
- NCT05074888
- Lead Sponsor
- Materia Medica Holding
- Brief Summary
The multicenter, double-blind, placebo-controlled, parallel-group, randomized clinical trial.
The objective of this study is to evaluate the efficacy and safety of Prospekta in the treatment of asthenia in patients after the coronavirus infectious disease (COVID-19).
- Detailed Description
Design: the multicenter, double-blind, placebo-controlled, parallel-group, randomized clinical trial.
The study will enroll adult patients of either gender aged 18 to 65 years after new coronavirus infection of 2019 (COVID-19) with symptoms of asthenia that appeared during or after an acute coronavirus infection (COVID-19) and persisting 4 to 12 weeks from the onset of coronavirus infection.
After the patient signs the patient information sheet and the informed consent form for participation in the study, complaints, medical history, physical examination, registration of vital signs are collected, the patient fills in the Fatigue Severity Scale (FSS) and Hospital Anxiety and Depression Scale (HADS). A six-minute walk test (6MWT) is carried out. The physician evaluates the severity of asthenia with FSS scale and records concomitant medications, co-morbidities and concurrent conditions.
If a patient meets all inclusion criteria and does not have any of the exclusion criteria at Visit 1 (Day 1), he/she is randomized to one of two groups: Group 1 - patients receive Prospekta at a dose of 1 tablet twice daily for 4 weeks; Group 2 - patients receive placebo on the study drug regimen.
The trial will use electronic patient diaries (EPD). The patient should record any possible deterioration (if applicable) in the EPD. At Visit 1 (Day 1), the physician will provide guidance on how to work with EPD, so that the patient can use it independently in the future.
At Visit 2 (Week 4 ± 3 days), the physician will collect patient's complaints, record physical examination data and vital signs as well as any changes in concurrent diseases and conditions. The patient fills out the FSS and HADS scales. A 6MWT is carried out. The physician monitors the prescribed treatment and use of concomitant medications, evaluates the safety of the study treatment and patient's compliance, filling out the diary.
The patient stops taking the study drug. At the end of the study treatment period, the patient is monitored for 4 weeks (follow-up period).
At Visit 3 (final visit, Week 8 ± 3 days), the physician collects patient's complaints, records physical examination data and vital signs, changes in concomitant diseases and conditions. The patient fills in the FSS and HADS scales. A 6MWT is carried out. The physician evaluates the safety of the study treatment, checks the completion of the diary.
During the study the patients are allowed to take medications for their chronic conditions, except for medicines listed as "Prohibited concomitant treatment".

Group Intervention Description Placebo Placebo Tablet for oral use. Placebo using Prospekta scheme. Prospekta Prospekta Tablet for oral use. 1 tablet twice daily. The tablets are taken outside of meals (between meals or 15 minutes before eating or drinking), keep the tablets in the mouth, without swallowing, until completely dissolved.
- Primary Outcome Measures
Name Time Method Change in the Mean FSS Score. after 4 weeks of treatment Fatigue Severity Scale (FSS). Change in the mean FSS score after 4 weeks of treatment. The total score of the scale, which consists of 9 questions, varies between 9-63. This scale consists of a 7-point Likert scale. 1 point means strongly disagree, 7 means strongly agree. People are asked to mark the appropriate options for each question taking into account their status in the last 1 month period. A total of 36 points and above indicate fatigue. A higher score is indicated high level of fatigue.
- Secondary Outcome Measures
Name Time Method Change in Distance of the 6-minute Walk Test. after 4 weeks of treatment Change in distance when performing the 6-minute walk test after 4 weeks of treatment. The test is carried out with the aim of objectively assessing the patient's physical tolerance. The patient should walk the maximum possible distance for himself at his own pace on a flat surface in 6 minutes.
Change in the Severity of Anxiety on the HADS Subscale. after 4 weeks of treatment Hospital Anxiety and Depression Scale (HADS). Change in the severity of anxiety and depression on the HADS subscales after 4 weeks of treatment.
