Phase I: Number of Participants With Any Adverse Event (AE) and Any Serious Adverse Event (SAE) Primary · From the start of study treatment until 30 days after study treatment discontinuation (average of 1.38 year)

An AE is defined as any untoward medical occurrence (MO) in a part. temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP and can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with its use. SAE is defined as any untoward MO that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, a congenital anomaly/birth defect and protocol-specific SAEs:ALT\>=3xup

Systolic blood pressure (SBP) and diastolic blood pressure (DBP) values were graded using (NCI CTCAE version 4.0). SBP was categorized as: G1 (Increase to \>=120 to 140 millimeters of mercury \[mmHg\]), G2 (Increase to \>=140 to \<160 mmHg), and G3 (Increase to \>=160 mmHg). DBP was categorized as: G1 (Increase to \>=80 to \<90 mmHg), G2 (Increase to \>=90 to \<100 mmHg), and G3 (Increase to \>=100 mmHg). The worst-case during the on-therapy period was determined taking into account both scheduled and unscheduled assessments. An increase is defined as an increase in the CTCAE grade relative to

Change from Baseline in heart rate is categorized as decrease to \<60 beats per minute (bpm), change to normal or no change, and increase to \>100 bpm relative to the Baseline value. Participants with a missing Baseline value are assumed to have a normal Baseline value. Participants were counted twice if the participant's heart rate value decreased to \<60 bpm and increased to \>100 bpm post-Baseline.

Phase I: Change From Baseline in Oxygen Saturation (SpO2) Measured Via Pulse Oxymetry at the Indicated Time Points Primary · From Baseline until the post-treatment Visit (average of 1.38 year)

Oxygen saturation measures the capacity of blood to transport oxygen to other parts of the body. Oxygen binds to hemoglobin in red blood cells when moving through the lungs. A pulse oximeter uses two frequencies of light (red and infrared) to determine the percentage of hemoglobin in the blood that is saturated with oxygen,that is called as blood oxygen saturation or SpO2. Change from Baseline was calculated as the individual post-Baseline value (Days 8,15; Weeks 3 to 136 and post-treatment Visit) minus the Baseline value. The Baseline value is defined as the last pre-treatment value observed.
