| Main Objective: The primary objective of this study is to evaluate the efficacy and safety of inhaled LASAG plus standard of care compared to placebo plus standard of care in patients hospitalized due to acute serious influenza OR an influenza caused worsening of a primary medical condition measured by time to alleviation of influenza symptoms. Influenza symptoms are defined as: • nasal congestion • sore throat • cough • aches/myalgia • fatigue • headaches • feverishness/chills/sweats Time to alleviation is defined as the time in hours from first inhalation of LASAG until at least 5 of 7 clinical influenza symptoms are rated with 0 (not present, i.e. like before the influenza) or 1 (mild) on the influenza symptom questionnaire without any use of symptom relief medication (i.e. acetaminophen) and remained so for at least 24±2 hours.;Secondary Objective: The main secondary objective is to evaluate the clinical efficacy of inhaled LASAG plus standard of care compared to placebo plus standard of care in patients hospitalized due to acute serious influenza OR an influenza caused worsening of a primary medical condition as measured by time to alleviation of the following clinical influenza signs: 1. Body Temperature • = 37.2 °C (= 99 °F) oral • = 37.8°C (= 100°F) rectal or tympanic 2. Oxygen saturation • = 92% (without oxygen feed) 3. Respiratory rate • = 24/minute 4. Heart rate • = 100/minute 5. Systolic BP • = 90 mm Hg Time to alleviation is defined as the time in hours from first inhalation of LASAG until resolution of at least 4 of the 5 clinical signs within resolution criteria given above and maintained for at least 24±2 hours without use of symptomatic relief medication (i.e. acetaminophen). 2 of the 4 resolution criteria have to be body temperature and oxygen saturation. ;Primary end point(s): Time to alleviation of clinical influenza symptoms which is defined as the time in hours from first inhalation of LASAG until at least 5 of 7 clinical influenza symptoms a | — |
