Number of Participants With Adverse Events (AEs)and Serious Adverse Events (SAEs)

Number of participants with ocular and non-ocular AEs and SAEs were separately recorded. An AE is an unfavorable change in the health of a participant, including abnormal laboratory findings, that happens during a clinical study or within a certain time period after the study has ended. This change may or may not be caused by the intervention being studied. An SAE is an adverse event that results in death, is life-threatening, requires inpatient hospitalization or extends a current hospital stay, results in an ongoing or significant incapacity or interferes substantially with normal life functions, or causes a congenital anomaly or birth defect. Medical events that do not result in death, are not life-threatening, or do not require hospitalization may be considered serious adverse events if they put the participant in danger or require medical or surgical intervention to prevent one of the results listed above.

Time frame: Approximately up to 6 months

Number of Participants With Abnormal Visual Acuity of Potential Clinical Concern (PCI)

Visual acuity was measured over 5 months and also during follow-up period. Visual acuity was measured using standardized early treatment of diabetic retinopathy study (ETDRS) visual acuity charts. Visual acuity measurement was performed by an examiner that had been appropriately trained. Screening, Month 2 and Month 5 data were considered as Best Corrected Visual Acuity (BCVA) data. A loss of greater than or equal to 15 letters in BCVA from Baseline was considered of PCI. Data for number of participants who met the criteria for PCI have been presented.

Time frame: Approximately up to 6 months

Number of Participants With Abnormal Pupil Examination of PCI

Pupil abnormalities were of different types. Meibomian gland dysfunction was measured as obvious inspissation (debris). Mild injection, no trichiasis (lid thickening), or two step worsening was analyzed. Afferent pupillary defect, motility examination, PERRL, confrontation visual field was measured as a new definite abnormality. Left and right both eyes were examined.

Time frame: Up to follow-up (approximately 6 months)

Number of Participants With Abnormal Conjunctival Examination of PCI

A two step worsening in the conjunctival examination was considered a value of PCI. Participants were analyzed for conjunctival examination up to follow-up (6 months).

Time frame: Up to follow-up (approximately 6 months)

Number of Participants With Abnormal Anterior Chamber Examination of PCI

A two step worsening in the anterior chamber examination was considered a value of PCI. The participants were examined for any anterior chamber abnormality. Fibrinous response and obvious aqueous haze were considered abnormalities related to anterior chamber examination.

Time frame: Approximately up to 6 months

Number of Participants With Abnormal Corneal Examination of PCI

A two step change in any of the lens opacity categories was categorized as of PCI. Corneal epithelium was defined as abnormal when punctate keratopathy was measured as mild, moderate, severe; epithelial edema was measured as subtle epithelial haze, mild patchy microcystic changes, diffuse microcystic changes, and/or investigator determined abnormality. Stromal opacity/ edema was measured by investigator when stroma identifies opacity or edema. Corneal staining was measured as obvious (\<=20) localized or diffuse punctate staining areas, severe localized or diffuse punctate staining. Participants were analyzed for any of the mentioned abnormality over 6 weeks (up to follow-up period).

Time frame: Approximately up to 6 months

Number of Participants With Abnormal Lens Opacity of PCI Using Age Related Eye Disease Study (AREDS) Scale

A two step change in any of the lens opacity categories was considered a value of PCI. Aphakia (surgical removal of lens) or pseudophakia was noted if any. Stroma opacity or edema was measured by investigator when it was detected as edema or opacity in stroma.

Time frame: Approximately up to 6 months

Number of Participants With Abnormal Tear Films of PCI

Tear film abnormalities were based on the clinical judgment of investigator. Tear film thickness was analyzed and it was reported whether the film was increased or decreased or was normal. Presence of debris or mucus was also reported. Other test were tear lake analysis and checking of discharge from eyes.

Time frame: Approximately up to 6 months

Number of Participants With Any Grade 2 Plus Worsening of Meibomian Gland Function

Meibomian gland dysfunction was measured as obvious insipisation/debris, mild injection, no trichiasis or lid thickening; inspisation, debris, obvious injection, lid thickening, may have trsichiasis; or a two step worsening. Any 2+ worsening of Meibomian gland function was considered a value of PCI.

Time frame: Approximately up to 6 months

Number of Participants With Abnormal (Dilated) Fundus Examination

Dilation of fundus was examined post dosing up to 6 months. Number of participants with abnormal change from Baseline indicating dilation of fundus of eye was reported. Change from Baseline was the value at indicated time point minus the Baseline value. The abnormalities were posterior vitreous separation, pale optic nerve, fluid in the posterior pole, drusen, thick arterio-venous changes, pigment changes, cystoids, macular edema, drying of posterior fluid or sub-retinal fluid, underlying central atrophy, and retinal pigment epithelial changes etc. Refraction measurement were determined at the screening and 2 month/5 month visits in order to determine BCVA.

Time frame: Approximately up to 6 months

Secondary Outcomes

Change From Baseline (Screening Visit) in BCVA at Month 2 and 5

Change from Baseline in BCVA is the value at indicated time point minus the Baseline value. BCVA at screening visit was used as statistical Baseline. Only data before post-dose intravitreal injection of Avastin/ Lucentis (IVT) has been presented. Arithmetic mean was presented as data values; however statistical analysis is based on means of observed case (OC) data. The screening was used as a Baseline visit that was within or at 14 days of Day 1. Screening visit BCVA values were used to perform statistical comparison at month 2 and 5.

Time frame: From Baseline (screening visit), Month 2, and Month 5

Change From Baseline (Screening Visit) in Optical Coherence Tomography (OCT) Central Subfield Over 5 Months

The OCT effect is a pharmacodynamics (PD) measure of daily repeated dosing of Pazopanib. The anatomic effects of pazopanib treatment were limited to investigator determined assessment of OCT central subfield retinal thickness due to heterogeneity of participant population and the low likelihood of utility of central reading center determination. The OCT equipment used was approved by central OTC reading center. OCT scans were collected at indicated time points and were evaluated by Investigator. Thus, grading of further secondary objectives was not performed as per the study team. Change from Baseline is the value at indicated time point minus the Baseline value. The screening was used as a Baseline visit that was within or at 14 days of Day 1. Screening visit BCVA values were used to perform statistical comparison at month 2 and 5.

Time frame: From Baseline (Screening visit) and up to 5 months

Change in Neo-vascular Size and Lesion Size Over Period

The analysis was planned to be performed up to 6 months; however, due to heterogeneity of the population and the low likelihood of the utility of the data, the anatomic effects of the pazopanib treatment in this treatment were limited to investigator determined assessment of OCT central subfield retinal thickness. Thus, the study team decided not to have DARC (central reading center) perform the grading for the secondary PD outcomes like lesion size and change with respect to time were not analyzed. Thus, data was not collected for this outcome measure.

Time frame: Up to 6 weeks

Number of Participants With Lesion Types Over Period

Number of participants with type of lesion were reported as determined by Investigator. Occult and minimally classic were the two types of lesions reported.

Time frame: Up to 6 months
