Brief Summary:
This is a 4-visit, multi-center, randomized, double-masked, parallel group study evaluating the safety and efficacy of CSF-1 in the treatment of presbyopia.

Condition or disease Intervention/treatment Phase
Presbyopia Drug: CSF-1 Drug: CSF-1 Component #1 Drug: CSF-1 Component #2 Phase 2

Detailed Description:
This is a 4-visit, multi-center, randomized, double-masked, parallel group study evaluating the safety and efficacy of CSF-1 in the treatment of presbyopia. Approximately 150 subjects will be enrolled across 7 study centers in the United States. At Visit 2, subjects will be randomized 1:1:1 to one of three treatment arms: CSF-1, CSF-1 Component #1, or CSF-1 Component #2. All subjects will dose twice a day in both eyes with a single drop of their assigned treatment for approximately 1 week. At Visit 3, subjects randomized to CSF-1 will now receive a different concentration of CSF-1, subjects randomized to CSF-1 Component #1 will receive a different concentration of CSF-1 Component #1 and subjects randomized to CSF-1 Component #2 will continue dosing with the same concentration of CSF-1 Component #2. All subjects will continue dosing twice a day in both eyes for approximately 1 week.

Arm Intervention/treatment
Experimental: CSF-1
This treatment arm consists of 2 different concentrations of CSF-1. Subjects randomized to the CSF-1 treatment arm will receive their first dose of CSF-1 in-office at Visit 2. All subjects will dose twice a day in both eyes with a single drop for approximately 1 week. At Visit 3, subjects randomized to the CSF-1 arm will now receive a different concentration of CSF-1. Subjects will continue dosing twice a day in both eyes for approximately 1 week.
Drug: CSF-1
This treatment arm consists of 2 different concentrations of CSF-1. Subjects randomized to the CSF-1 treatment arm will receive their first dose of CSF-1 in-office at Visit 2. All subjects will dose twice a day in both eyes with a single drop for approximately 1 week. At Visit 3, subjects randomized to the CSF-1 arm will now receive a different concentration of CSF-1. Subjects will continue dosing twice a day in both eyes for approximately 1 week.

Active Comparator: CSF-1 Component #1

This treatment arm consists of 2 different concentrations of CSF-1 Component #1.

Subjects randomized to the CSF-1 Component #1 treatment arm will receive their first dose of CSF-1 Component #1 in-office at Visit 2. All subjects will dose twice a day in both eyes with a single drop for approximately 1 week. At Visit 3, subjects randomized to the CSF-1 Component #1 arm will now receive a different concentration of CSF-1 Component #1. Subjects will continue dosing twice a day in both eyes for approximately 1 week.

Drug: CSF-1 Component #1

This treatment arm consists of 2 different concentrations of CSF-1 Component #1.

Subjects randomized to the CSF-1 Component #1 treatment arm will receive their first dose of CSF-1 Component #1 in-office at Visit 2. All subjects will dose twice a day in both eyes with a single drop for approximately 1 week. At Visit 3, subjects randomized to the CSF-1 Component #1 arm will now receive a different concentration of CSF-1 Component #1. Subjects will continue dosing twice a day in both eyes for approximately 1 week.


Active Comparator: CSF-1 Component #2
This treatment arm consists of a single concentration of CSF-1 Component #2. Subjects randomized to the CSF-1 Component #2 treatment arm will receive their first dose of CSF-1 Component #2 in-office at Visit 2. All subjects will dose twice a day in both eyes with a single drop for approximately 1 week. At Visit 3, subjects randomized to the CSF-1 Component #2 arm will continue dosing with the same concentration of CSF-1 Component #2. Subjects will continue dosing twice a day in both eyes for approximately 1 week.
Drug: CSF-1 Component #2
