Clinical adverse event (AE) were graded using the Division of Acquired Immunodeficiency Syndrome (DAIDS) table for grading the severity of adult and pediatric AE Version 1.0, December 2004; Clarification August 2009. The grades were: 1 (mild)=Symptoms causing no or minimal interference with usual social and functional activities; 2 (moderate)= Symptoms causing greater than minimal interference with usual social and functional activities; 3 (severe)= Symptoms causing inability to perform usual social and functional activities; 4 (potentially life threatening): Symptoms causing inability to perform basic self-care functions or medical or operative intervention indicated to prevent permanent impairment, persistent disability, or death. Data has been presented for any Grade 2 or higher event in the injection phase for injection phase (Week 5- Week 41).

The concurrent medications that were consumed by participants during the injection phase were of the class nervous system, musculo-skeletal system, genito urinary systems and sex hormones, various, respiratory system, dermatologicals, alimentary tract and metabolism, sensory organs, systemic hormonal preparations, excluding sex hormones, blood and blood forming organs, cardiovascular system. The participants who took medication from any of the above class of during the injection phase (Week 5-Week 41) have been presented.

The severity of laboratory results was graded according to the DAIDS table for grading the severity of adult and pediatric AE Version 1.0, December 2004; Clarification August 2009. The DAIDS displays events as Grades 1-5 based on this general guideline: Grade 1, mild; Grade 2, moderate; Grade 3, severe; Grade 4, potentially life threatening. Data for Number of participants who experienced grade 2 or higher laboratory results in the injection phase (Week 5-Week 14) have been presented.

Full 12-lead ECGs included heart rate, PR, QRS, QT and QTc intervals. Measurements were taken from the participant following 5 minutes of rest in a semi-supine position. ECGs were performed at Week 5, Week 17, Week 29 and Week 41 in the injection phase (Week 5-Week 41). ECG abnormalities characterized as abnormal-not clinically significant (A-NCS) and abnormal-clinically significant (A-CS) upto Week 41 have been presented. There were no A-CS findings for ECG in the injection phase.

Vital signs measurements were performed for SBP and DBP following 5 minutes of rest. Baseline was defined as the first injection at Week 5 for the injection phase. Change from Baseline was calculated by subtracting the Baseline value from the individual post-Baseline value at Week 17, Week 29 and Week 41.

Vital signs measurements were performed for HR following 5 minutes of rest. Baseline was defined as the first injection at Week 5 for the injection phase. Change from Baseline was calculated by subtracting the Baseline value from the individual post-Baseline value at Week 17, Week 29 and Week 41.

Common ISR included pain, erythema, nodules and any other ISR with greater or equal to 5 participants. The number of participants who experienced pain events by needle length, swelling events by needle length, bump events by needle length for injection phase by maximum grades have been presented for the injection phase (Week 5-Week 41).
