An AE was any untoward medical occurrence in a participant who received investigational product without regard to possibility of causal relationship. SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly; medically important events. A treatment emergent AE was defined as an event that emerged during the treatment period that was absent before treatment, or worsened during the treatment period relative to the pretreatment state. AEs included both serious and non-serious adverse events. TEAEs were summarized for each cohort (Cohort 1 and Cohort 2, irrespective of treatment received), each treatment group and the total of treatment groups, using the merged data of studies A0221047 and A0221109 as planned.

Visual acuity (VA) was assessed for each eye using the Snellen method, where logarithm of minimum angle of resolution (logMAR) units were derived from the Snellen ratios. Participants had to read letters from the chart at a distance of 20 feet/6 meter or 4 meter. VA (Snellen ratio) = distance between the chart and participant, divided by distance at which participant was able to see/read chart without impairment; expressed as decimal. logMAR = log10 (1/decimal VA). In this outcome measure, data have been reported for right and left eye separately. Data for this outcome measure was planned to be analyzed for each treatment group of study A0221109 only.

The visual accommodation was the minimum focusing distance for each eye at which vision became blurred - the mean of triplicate measurements. The participants focused on a single letter of the 20/40 line of an eye chart and chart was moved slowly towards the participant until letter was blurred. At this point, the distance from eye to letter was measured for each eye. In this outcome measure data have been reported for right and left eye separately. Data for this outcome measure was planned to be analyzed for each treatment group of study A0221109 only.

CBCL: assessed child's behavioral and emotional problems. Parent/caregiver of child answered 120 items, each on scale: 0=not true, 1=somewhat/sometimes true, 2=very/often true. 103 items were categorized in 8 domains: aggressive behavior, anxious/depressed, attention problems, rule-breaking behavior, social problems, somatic complaints, thought problems, withdrawn. Summary scores: Internalizing problems =anxious/depressed+withdrawn+somatic complaints; Externalizing problems =rule-breaking+aggressive behavior. Total problems =8 domains+other 17 items. Raw scores for each domain, summary and total problems =sum of scores of related items. Using ADM tool raw scores transformed/derived into standard T-scores, range: each domain=50-100, internalizing problems=34-100, externalizing problems=33-100, total problems=24-100. Lower T-score (8 domain,2 summary,total problems)=better outcomes. Data for this outcome measure was planned to be analyzed for each treatment group of study A0221109 only.

The grooved pegboard test was a manipulative dexterity test that assessed psychomotor speed, fine motor control, and rapid-visual motor coordination. Participants were asked to insert 10 grooved pegs into holes within the given time limit up to 300 seconds. The task needs to be completed once for each hand; firstly, using the dominant hand followed by the non-dominant hand. Time taken to complete the test was inversely correlated to the cognitive ability. Participants were assigned to either a 10 or 25-peg assessment based on their age. 10-peg assessment was done on participants below age of 9 years. In this outcome measure data for dominant and non-dominant hand have been reported separately.
