Who can take part

You may be able to join if

1. Able to understand and sign an informed consent form prior to participation in any study-related procedures.
2. Male or female subjects ≥ 18 years.
3. Presence of all the following at Screening: a. diagnosis of acquired ptosis in both eyes with MRD 1 ≥0 and ≤ 2 mm in the study eye b. Snellen VA of 20/80 or better in both eyes Note: MRD1 is defined as the distance between upper eye lid margin and centre of the pupil. MRD0 is defined as the upper eye lid margin at the centre of the pupil. Measurement of MRD1 will be done by a Central Reading Centre. If the centre of the pupil cannot be determined by the Central Reading Centre due to negative MRD1, the subject will be deemed ineligible
4. Females who are 1-year postmenopausal, surgically sterilised, or females of childbearing potential with a negative urine pregnancy test at screening (Visit 1). Females of childbearing potential must use an acceptable form of contraception throughout the study. Acceptable methods include the use of at least one of the following: intrauterine (intrauterine device), hormonal (oral, injection, patch, implant, ring), barrier with spermicide (condom, diaphragm), or abstinence.
5. A male subject with a female partner of childbearing potential should use or practice an acceptable contraceptive method, such as abstinence, condom or vasectomy (surgery at least 6 months prior to signing the study ICF and beginning screening), or other contraception deemed adequate by the investigator during the study.
6. Able to self-administer study treatment or to have the study treatment administered by a caregiver throughout the study period.

You likely can't join if

1. Congenital ptosis.
10. Poor fixation or abnormal eye position which prevents from taking reliable pictures for MRD1 measurement.
11. History of closed/narrow angle glaucoma (unless patent peripheral iridotomy has been performed at least 3 months prior to screening (Visit 1).
12. Facial including periocular neurotoxin (e.g., Botox, Xeomin, Dysport, Myobloc) injections within 3 months prior to screening (Visit 1) and during the study.
13. Topical application of bimatoprost (i.e., Latisse®) to the eyelashes within 8 days prior to screening (Visit 1) and during the study.
14. Mechanical ptosis e.g., ptosis due to orbital, corneal or lid tumor, cicatricial processes affecting the movements of the upper lid, and enophthalmos.

Females of childbearing potential must use an acceptable form of contraception throughout the study. Acceptable methods include the use of at least one of the following: intrauterine (intrauterine device), hormonal (oral, injection, patch, implant, ring), barrier with spermicide (condom, diaphragm), or abstinence.

6. Able to self-administer study treatment or to have the study treatment administered by a caregiver throughout the study period.
7. An answer of ‘Yes’ to the question ‘Does the ptosis cause enough burden to the subject to want to receive treatment for it’.
8. Loss of ≥ 8 points not seen at or above 10° from fixation in the superior visual field of a reliable HVF 36-point ptosis protocol test at screening visit in the same eye with MRD1 ≥0 and ≤ 2 mm. If both eyes have MRD1 ≥0 and ≤ 2 mm the more ptotic eye (the eye with the smaller MRD1 measurement) will be the study eye. If the MRD1 is the same in both eyes, the eye with the worse VF will be the study eye. If the MRD1 and VF is the same in both eyes, the right eye will be the study eye. The HVF Analyzer will determine if the visual field test is reliable. If the HVF Analyzer issues an “XX” for fixation losses, false positives, and/or false negatives, the test will be deemed unreliable. If deemed unreliable, the test must be retaken once per scheduled screening visit. If a reliable visual field cannot be obtained, the subject will be a screen failure.
