Brief Summary:

The main purpose of this study is:

• to evaluate the efficacy and safety of MMH-407 in the treatment of influenza in outpatient adults.

Condition or disease Intervention/treatment Phase
Influenza Drug: MMH-407 Drug: Placebo Phase 3

Detailed Description:

Design: a multicenter, placebo-controlled, double-blind, randomized clinical trial in parallel groups.

The study will include both male and female patients aged 18-64 years with clinical signs of influenza within the first 24 hours of the onset of illness.

The influenza diagnosis must be supported by a positive rapid test (detection of influenza virus antigens in nasal epithelial cells). After the patients provide signed Participant Information Sheet and Informed Consent form, their medical history and body temperature will be recorded and physical examination and rapid diagnostic test performed. Patients who test positive will be assessed for 7 influenza-associated symptoms: cough, sore throat, headache, nasal congestion, feverishness or chills, muscle or joint pain, fatigue.

4-point Flu Symptom Severity scale will be used: 0 = no symptom; 1 = mild symptom; 2 = moderate symptom; 3 = severe symptom.

Nasopharyngeal swabs will be obtained from these patients for subsequent real-time reverse transcription polymerase chain reaction (RT-PCR) influenza A/B testing and laboratory tests performed.

If a patient meets all inclusion criteria and does not meet any of the exclusion criteria at Visit 1 (Day 1), he/she will be randomized into one of the treatment groups: Group 1: ММН-407 for 5 days, or Group 2: Placebo on the ММН-407 regimen for 5 days.

The patients will use electronic patient diaries to daily record their morning and evening axillary temperature (taken using a Geratherm mercury-free thermometer) and severity of 7 influenza-associated symptoms (using the Flu Symptom Severity scale). In addition to this, the patients will record doses of antipyretic drugs taken (when applicable) and any worsening of their health status (when applicable, to assess treatment safety and collect adverse events data).

In total, patients will be observed for 14 days (screening and randomization - up to 24 hours, treatment - 5 days, subsequent observation - up to 2 days; and a follow-up 'telephone' visit - Day 14).

During the study, 3 visits from patient to the physician's office and a follow-up telephone visit will be accomplished: 1) patient visits - Days 1, 3 and 7 (Visits 1, 2, and 3) at the medical centre; 2) telephone visit from the physician (Visit 4) - Day 14.

During Visits 2 and 3, the physician will perform a physical examination, record the changes in patients' symptoms and the use of concomitant medications and check the completion of patient diaries. At Visit 2, nasopharyngeal swabs for RT-PCR will be collected. Visit 3 will involve an assessment of treatment compliance and laboratory tests. The telephone visit is intended to provide information on a patient's health status, presence/absence of secondary bacterial complications and the use of antibiotics.

During the study, subjects will be allowed to use symptomatic therapy and medications for their co-morbidities, except for the medicines listed in the "Prohibited Concomitant Medications" section.

Arm Intervention/treatment
Experimental: MMH-407
Oral administration. Single dose: 1 tablet. First 24 hours of therapy: 1 tablet every 30 minutes for the first 2 hours, followed by 3 more tablets taken at regular intervals during the rest of the day. Days 2 to 5: 1 tablet 3 times daily.
Drug: MMH-407
MMH-407: For oral use.

Placebo Comparator: Placebo
Oral administration. Single dose: 1 tablet. First 24 hours of therapy: 1 tablet every 30 minutes for the first 2 hours, followed by 3 more tablets taken at regular intervals during the rest of the day. Days 2 to 5: 1 tablet 3 times daily.
Drug: Placebo
Placebo: For oral use.

Primary Outcome Measures :
  1. Time to improvement of influenza symptoms. [ Time Frame: On days 1-14 of observation. ]
    Based on patient diaries. In the morning and in the evening, the patients rate the severity of their symptoms on a 4-point scale (7 symptoms of influenza): headache, fever/chill, aches in the muscles/joints, weakness/drowsiness, cough, sore throat, and nasal congestion, where the absence of symptoms is 0, mild symptoms - 1, moderate symptoms - 2, and severe symptoms is 4. "Improvement of influenza symptoms" means no or mild symptoms.

Secondary Outcome Measures :
  1. Proportion of patients reporting improvement of influenza symptoms. [ Time Frame: On days 1-14 of observation period. ]
    Based on patient diaries.

  2. Severity of illness. [ Time Frame: On days 1- 6 of the observation period. ]
    Total symptom score AUC (to be estimated from each of the seven symptom subscores).

  3. Proportion of patients with negative virus shedding. [ Time Frame: On day 3 of the observation period. ]
    Negative influenza RT-PCR on nasopharyngeal swabs.

  4. Dosing frequency of antipyretics according to indications. [ Time Frame: On days 1-3 of the treatment period. ]
    A decrease dosing frequency of antipyretics while taking MMN-407 is one of the criteria for effectiveness.Based on patient diaries.

  5. Proportion of subjects reporting worsening of illness. [ Time Frame: On days 4 -14 of the observation period. ]
    Worsening of illness is bacterial complication of influenza that require the use of antibiotics or hospitalization.

  6. Occurrence and nature of adverse events (AE). [ Time Frame: On days 1-5 of the treatment period. ]
    AE severity, causal relationship to the study drug and outcome.

  7. Number of patients with treatment-related changes in vital signs: body temperature, pulse rate (heart rate), respiration rate (breathing rate), and blood pressure. [ Time Frame: On days 1- 5 of the treatment period. ]
    Based on medical records. Vital signs will be measured in a medical setting.

  8. Proportion of subjects with clinically significant abnormal laboratory data. [ Time Frame: On days 1- 5 of the treatment period. ]
    Вased on medical records.
