First-in-Human Study of LHA510 in Elderly Subjects and Patients With Age-Related Macular Degeneration

This first-in-human study will be conducted in two parts. Part 1 is a single ascending dose
(SAD) design to assess the local ocular and systemic safety and tolerability of a single
topical eye drop of LHA510 administered at various concentrations. Four separate cohorts of
unique elderly subjects (55 to 80 years) will be utilized, with each cohort randomized to
receive either topical LHA510 or vehicle in a 3:1 ratio as a single dose. A disposition
evaluation will be performed 7 days later. Part 2 is a multiple ascending dose (MAD) design
to assess the local ocular and systemic safety and tolerability of LHA510 administered at
various concentrations and dosing frequencies. Six separate cohorts of unique AMD subjects
will be utilized, with each cohort randomized to receive either topical LHA510 or vehicle in
a 3:1 ratio for 7 days. A disposition evaluation will be performed 14 days after the first
dose of study drug. A review of all available safety data will be conducted by the Sponsor
and the PI(s) prior to dose escalation (cohort progression).
