Pharmacokinetic (PK) Study of GSK933776 in Healthy Volunteers

This study is intended to enable a possible transition to intramuscular (IM) or subcutaneous (SQ) administration for subsequent studies with GSK933776 by characterizing the safety, tolerability, PK and pharmacodynamic profiles, and immunogenicity of GSK933776 following IM and SQ administration in healthy volunteers. Such alternate routes of administration may provide more options in the selection of an efficacious dose for subsequent development in patients with geographic atrophy. There will be four treatment arms in the study and participants will be assigned to 1 of 4 possible treatment arms in a 1:1:1:1 ratio. The planned number of evaluable participants for this study is 24 with 6 participants completing all critical assessments in each of the four treatment arms. The total duration of participation from screening to follow-up for Treatment Arms A, B and D (single dose of GSK933776), will be approximately 113 days and total duration for Treatment Arm C (repeat dose of GSK933776) will be approximately 134 days.
