12 Week Patient Study in Neovascular Age-related Macular Degeneration (AMD)

CRLT was the manual measurement of the distance between the inner limiting membrane of the retina and the inner border of the choriocapillaris, inclusive of subretinal or sub-retinal pigment epithelium fluid collections and of the thickness of any observable choroidal neovascular membrane or scar tissue, evaluated in the central 1 mm of the Cube scan. OCT assessments were performed using SPECTRALIS spectral domain OCT. Baseline was defined as the assessments performed between Day -3 to -1. Change from Baseline was calculated by subtracting the Baseline value from the individual post-randomization value at Day 29.

OCT was used for the determination of retinal morphology changes in the study eye which included assessments of SR fluid (an exudate between the retina and choroid from various sources including the vitreous cavity, subarachnoid space, or abnormal vessels) and PED (retinal pigment epithelium separates from the underlying Bruch's membrane due to the presence of blood, serous exudate, drusen, or a neovascular membrane). Baseline was defined as the assessments performed between Day -3 to -1. Change from Baseline was calculated by subtracting the Baseline value from the individual post-randomization value at Day 29.

BCVA was measured in the study eye using the EVA chart starting at a test distance of 4 meters. The BCVA score is the number of letters read correctly by the participant. A decrease in the BCVA score indicates a worsening of vision while higher scores indicates improvement of VA. Baseline was defined as the assessments performed between Day -3 to -1. Change from Baseline was calculated by subtracting the Baseline value from the individual post-randomization value at Day 29.

CNV was the measurement of the combined classic and occult neovascular lesion including areas of classic neovascularization, late staining of undetermined origin and fibrovascular PED. CNV total lesion complex size was the measurement of the entire lesion including classic and occult neovascular components as well as contagious blood and/or blocked fluorescence and/or serous PED. FA uses fundus photography (FP) to capture images of injected dye circulating throughout the retinal blood vessels to assess leaking, swelling/circulation problems caused by various eye diseases like diabetic retinopathy and wet macular degeneration. A fluorescein angiogram was obtained at Day 29. Images were evaluated by investigator for eligibility and by a central reading center for determination of PD effect. Baseline was defined as the assessments performed between Day -3 to -1. Change from Baseline was calculated by subtracting the Baseline value from the individual post-randomization value at Day 29.

Fundus photography involves capturing of images of the center of the very back inner wall of the eye - the retina, optic nerve, macula and main retinal blood vessels. The parameters assessment were heme SR hemorrhage (absence or presence at the location), heme IR hemorrhage (absence or presence at the location), SR fluid (absence or presence at location), fibrosis (absence or presence at location), atrophy (absence or presence of atrophic changes) and pigment (absence or presence at location). A protocol set of fundus photographs were obtained at Day 29. Images were read by the investigator for eligibility determination, and by a central reading center for determination of PD effect. Data has been presented for number of participants with changes in eye characteristics in the study eye at Day 29.

At any time during the study, including the follow-up period, rescue treatment (standard of care) was given based on the clinical judgment of the investigator. Rescue treatment was to be strongly considered for participants whose center subfield thickness had increased by >50 microns from the lowest value on study or whose BCVA decreased by more than 5 letters compared to baseline and who also had persistent fluid by OCT. Data has been reported for the number of participants with their percentages who required any rescue medication administration until follow-up.

An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, may jeopardize the participant or require medical or surgical intervention to prevent one of the other outcomes listed in the definition above, or is an event of possible drug-induced liver injury.

A complete eye examination was performed to include the following: Examination of eyelids and lashes (including meibomian glands), Pupil, motility and confrontation visual field examination, Slit lamp evaluation of anterior ocular structures (including conjunctiva, tear film, cornea with fluorescein staining, anterior chamber, iris, lens, and anterior vitreous), Intraocular pressure (IOP) measurement and Dilated Fundus Examination (Indirect ophthalmoscopy and slit lamp biomicroscopy). Data has been presented in a consolidated format for the total number of participants with values of potential clinical concern for complete ophthalmic examinations until Day 102.

Vital sign assessments included systolic blood pressure, diastolic blood pressure and heart rate. The potential clinical concern range for systolic blood pressure was <85 and >160 millimeters of mercury, diastolic blood pressure <45 and > 100 millimeters of mercury, heart rate <40 and >110 beats per minute. Data has been presented in a consolidated format for the total number of participants with values of potential clinical concern for systolic blood pressure, diastolic blood pressure and heart rate until Day 102.

Clinical chemistry parameters included albumin, alkaline phosphatase, alanine amino transferase, aspartate amino transferase, direct bilirubin, total bilirubin, calcium, chloride, carbon dioxide, creatinine, thyroxine (T3 free), gamma glutamyl transferase, glucose, potassium, sodium, total protein, total T3, urea, uric acid while hematology included basophils, eosinophils, hemoglobin, hematocrit, lymphocytes, mean corpuscle hemoglobin concentration, mean corpuscle hemoglobin, mean corpuscle volume, monocytes, segmented neutrophils, total neutrophils, platelet count, red blood cell count, reticulocytes and white blood cell count. The potential clinical concern ranges were as follows: glucose-low <3 and high >9 millimoles per liter (mmol/L), carbon dioxide-low <18 and high >34 mmol/L, lymphocyte-low <0.8 giga per liter (G/L) and platelet count was <100 and high >550 G/L. Data has been presented for the number of participants with values high and low of potential clinical concern.

Urinalysis measurements included assessments for red blood cells and white blood cells via microscopic examination while assessments for urine protein by standard dipstick analysis. Data has been presented for the number of participants with abnormal urinalysis results.

Throughout the study, 1 to 4 blood samples (2 mL) were collected from each participants for the analysis of plasma pazopanib concentrations between 0.55 to 10.83 hours post-dose on Weeks 2, 3, 4, 6 (unplanned), 8 (unplanned) and 12. The concentrations from the three blood samples per participant were averaged and then the values were averaged through all the participants. Blood samples were collected without restriction for the time interval between blood draw and the last dose of pazopanib eye drops.
