About this study

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CSF-1Drug

    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.

  • CSF-1 Component #1Drug

    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.

  • CSF-1 Component #2Drug

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects With ≥ 3 Lines Gain in Near Best Distance Corrected Visual Acuity (BDCVA) (at 40 cm)

    Number of subjects with a ≥ 3-line gain in near BDCVA (at 40 cm) at 1 hour post dose after 1 week treatment with CSF-1-Fixed Dose Combination (FDC) low dose (pilocarpine HCl 0.2% + diclofenac 0.006%) or pilocarpine HCl 0.2% alone or diclofenac 0.006% alone

    Measured: 1 hour post dose on day 8

  2. Number of Subjects With ≥ 3 Lines Gain in BDCVA (at 40 cm)

    Number of subjects with a ≥ 3-line gain in near BDCVA (at 40 cm) at 1 hour post dose after 1 week treatment with CSF-1-FDC (pilocarpine HCl 0.4% + diclofenac 0.006%) or pilocarpine HCl 0.4% alone or diclofenac 0.006% alone

    Measured: 1 hour post dose on day 15

Secondary outcomes (2)
  1. Number of Subjects With ≥ 2 Lines Gain in BDCVA (at 40 cm)

    Number of subjects with a ≥ 2-line gain in near BDCVA (at 40 cm0 at 1 hour post dose after 1 week treatment with CSF-1-FDC (pilocarpine HCl 0.2% + diclofenac 0.006%) or pilocarpine HCl 0.2% alone or diclofenac 0.006% alone

    Measured: 1 hour post dose on day 8

  2. Number of Subjects With ≥ 2 Lines Gain in BDCVA (at 40 cm)

    Number of subjects with a ≥ 2-line gain in near BDCVA (at 40 cm) at 1 hour post dose after 1 week treatment with CSF-1-FDC (pilocarpine HCl 0.4% + diclofenac 0.006%) or pilocarpine HCl 0.4% alone or diclofenac 0.006% alone

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CSF-1, CSF-1 Component #1 and CSF-1 Component #2 in people with Presbyopia, run by Orasis Pharmaceuticals Ltd. at 7 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Jan 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Subjects With ≥ 3 Lines Gain in Near Best Distance Corrected Visual Acuity (BDCVA) (at 40 cm) (time frame: 1 hour post dose on day 8). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jan 2023.
