The study will be conducted in two parts.

PART 1
Eligible participants will be randomized to 1 of 3 treatment groups in a ratio of 1:1:1.
Group 1: oral BEZ235 5 mg capsules taken once daily for 16 weeks
Group 2: oral BEZ235 10 mg capsules daily taken once daily for 16 weeks
Group 3: oral Matched placebo capsules taken once daily for 16 weeks

PART 2
Group 1: Chosen oral BEZ235 capsule dose from Part 1 (dose showing greatest efficacy with good tolerability) taken once daily for 16 weeks
Group 2: oral BEZ235 10 mg capsule + oral RAD001 0.1 mg tablets taken once daily for 16 weeks
Group 3: oral Placebo capsule taken once daily for 16 weeks
Part 2 will be conducted in the Northern Hemisphere with a different set of participants.

all medications to be given to participants will be Adherence to the treatment will be monitored by reviewing patient diary entries and monitoring returned treatment bottles.
Intervention code [1] 297531 0
Prevention
Comparator / control treatment
Placebo will be used as the control and comparator for the study for both Part 1 and Part 2.

BEZ235 matching placebo will be presented in a hard gelatin capsule and has the same contents minus the active ingredient.
Control group
Placebo

Outcomes
Primary outcome [1] 301497 0
Determine the efficacy of 2 different doses of BEZ235 alone or in combination with RAD001 on the incidence of respiratory tract infection in elderly subjects. The outcome will be assessed by physicians using chest x-ray, blood tests, etc.
Timepoint [1] 301497 0
16 weeks from start of treatment
Secondary outcome [1] 332863 0
Assess the safety and tolerability of 2 different doses of BEZ235 alone or in combination with RAD001. This outcome will be assessed by following adverse event reports, safety labs (hematology and chemistry) and physical exams.
Timepoint [1] 332863 0
7 days post-dose (16 weeks treatment plus 7 days)
Secondary outcome [2] 332864 0
Evaluate the effect of BEZ235 alone or in combination with RAD001 compared to placebo on the incidence of respiratory tract infections (RTIs) for 24 weeks. The outcome will be assessed by physicians using using chest x-ray, blood tests, etc.
Timepoint [2] 332864 0
24 weeks from start of treatment
Secondary outcome [3] 332865 0
Evaluate the effect of BEZ235 alone or in combination with RAD001 compared to placebo on the incidence of laboratory-confirmed viral RTIs for 16 weeks as assessed by respiratory virus PCR of nasopharyngeal swabs
Timepoint [3] 332865 0
16 weeks from start of treatment
Secondary outcome [4] 332866 0
Evaluate the pharmacokinetics (PK) of 2 different doses of BEZ235 given alone or in combination with RAD001. PK parameters such as AUC, Tmax, T1/2 will be assessed. RAD concentrations will be measured in blood. BEZ concentrations will be measured in serum.
Timepoint [4] 332866 0
At week 4, 6 and 8 after start of treatment

or
B. Age 65 years and above with one or more of the following conditions:

c. diastolic blood pressure, 50-95 mm Hg
d. pulse rate, 40 - 95 bpm
5. Subjects must weigh at least 40 kg
Minimum age
65 Years

Statistical methods / analysis
Data from two previous clinical trials conducted by Novartis (CRAD002X2202 and CBEZ235Y2201) suggests that 6 weeks of treatment of elderly participants 65 years of age and above with low doses of BEZ235 and/or RAD001 was safe and decreased the incidence of RTIs. The risk/benefit of BEZ235 alone or in combination with RAD001 may be most favorable in elderly subjects who are at increased risk of RTI-related morbidity and mortality. Therefore in the current study, elderly participants who are considered at increased risk of RTI-related morbidity and mortality will be enrolled.

The null hypothesis is that TRUE underlying proportion of patients with at least one RTI ocurrence is equal in all treatment arms. The alternative hypothesis is that at least one of the active treatment arms has TRUE underlying proportion of patients with at least one RTI ocurrence greater than that of placebo. The hypotheses will be assessed as described in the protocol.
