Safety And Tolerability Study Of RN6G In Subjects With Advanced Dry, Age-Related Macular Degeneration Including Geographic Atrophy

The dose was considered intolerable if a participant developed either ocular toxicity or other toxicity as per Common Terminology Criteria for Adverse Events (CTCAE) or based on the investigator's discretion. Ocular toxicity included: Grade >= 3 (retinopathy, retinal detachment, cataract formation, optic disk edema, keratitis, vitreous hemorrhage and uveitis) and acute vision loss of greater than 3 lines of vision up to and including 140 days after the first dose. Other toxicity included serious adverse event (SAE), Grade >= 3 (increased liver transaminases, encephalopathy/leukoencephalopathy, diarrhea, enteritis or nausea, prolongation of QT interval [Fridericia's correction]), Grade >=2 (central nervous system hemorrhage, decreased total leukocyte count, increased serum creatinine) and thrombocytopenia <100*10 9 /liter.

AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent are events between first dose of study drug and up to Day 304/ET that were absent before treatment or that worsened relative to pretreatment state. AE was assessed according to severity; Grade 1 (mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated), Grade 2 (moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living [ADL]), Grade 3 (severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL), Grade 4 (life-threatening consequences; urgent intervention indicated) and Grade 5 (death related to AE).

All causalities AE was any untoward medical occurrence in participant who received study drug without regard to causal relationship. Drug-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-emergent are events between first dose of study drug and up to Day 304/ET that were absent before treatment or that worsened relative to pretreatment state. All causalities and drug-related AEs reported wherein drug-related AEs were reported as ocular and non-ocular AEs. Ocular AEs were events which were localized in the ocular region and non-ocular AEs were systemic events which were not localized but occurred throughout the systemic circulation.

Systemic TEAEs were events which were not localized but occurred throughout the systemic circulation and reported as related and non-related to study drug.

The immunogenicity of RN6G (PF-04382923) in terms of producing an antidrug antibody (ADA) and neutralizing antibody response were assessed. Neutralizing antibody response were to be assess in participants with positive ADA samples.

Area under the concentration-time profile from time zero to time tau (τ), the dosing interval, where tau = 672 hours.

Css is the concentration of the drug at the state when the amount of drug administered is equal to the amount of drug eliminated.

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Steady state volume of distribution (Vss) is the apparent volume of distribution at steady-state.

The mean total time drug resides in the body.

CL is a quantitative measure of the rate at which a drug substance is removed from the body.

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

Amyloid (A) Beta (1-X) is a primary activator of complement in Alzheimer's disease (AD).

Criteria for changes in ECG (12-lead) were defined as: PR interval >=220 millisecond (msec) and increase of >=20 msec; QRS interval >=120 msec; QT interval corrected using the Bazett's formula (QTcB) >=500 msec; Maximum Change from Baseline in QTcF at Borderline >=30 msec to <60 msec and Prolonged >=60 msec.

Following parameters were analyzed for laboratory examination: Bilirubin, Direct Bilirubin, Blood Urea Nitrogen(BUN), Creatinine, Uric Acid, Calcium, Phosphate, Glucose, Cholesterol (CL)(Fasting), Triglycerides (Fasting) (TG), Immunoglobulin G (Ig G), Immunoglobulin A (Ig A), Immunoglobulin M (Ig M)

Following parameters were analyzed for laboratory examination: Aspartate Aminotransferase (AMT), Creatine Kinase (CK), Alanine Aminotransferase (ALT), Gamma Glutamyl Transferase (GGT), Lactate Dehydrogenase (LD), Alkaline Phosphatase (AP).

Following hematology parameters were analyzed for laboratory examination: Hemoglobin, Hematocrit, Red blood cell (RBC) count, Platelet count, WBC count, Total neutrophils (Abs),Eosinophils (Abs),Monocytes (Abs),Basophils (Abs), Lymphocytes (Abs).

Following hematology parameters were analyzed for laboratory examination: Prothrombin Time (PT), Partial Thromboplastin Time.

Urine specific gravity is a measure of the ratio of the density of urine to the density of water.

Urine pH is a method for evaluating urine acidity measured on a 10-point scale ranging from 0 (most acidic) to 9 (most alkaline). A lower pH means more acidity.

QT interval corrected using the Fridericia formula (QTcF) >=500 msec; Maximum Change from Baseline in QTcF at Borderline >=30 msec to <60 msec and Prolonged >=60 msec.
