A Study in Chinese Patients With Acquired Blepharoptosis

May 13, 2026 updated by: Santen Pharmaceutical Co., Ltd.

A Multicenter, Randomized, Double-Masked, Placebo-Controlled Parallel Group Phase III Study to Evaluate the Efficacy and Safety of STN1013800 Ophthalmic Solution in Chinese Patients With Acquired Blepharoptosis

This is a Phase III Study to evaluate the efficacy and safety of STN1013800 Ophthalmic Solution in Chinese Patients with Acquired Blepharoptosis.

At present, there are no medicines for the treatment of acquired blepharoptosis in China.

Therefore, to evaluate the efficacy and safety of 0.1% STN1013800 ophthalmic solution, Vehicle (Placebo) are designed.

For the screening period, 3-7 days were set to confirm the subjects and judge their qualification. Dosage and administration were based on prior clinical trial results approved at 0.1% once daily for 42 days treatment.

Description

Inclusion Criteria:

  • At least one eye diagnosed with acquired blepharoptosis and presence of all the following criteria at screening:

    • Loss of reliable Leicester Peripheral Field Test (LPFT) of ≥ 8 points in the top 2 rows (LPFT Eligibility Score); subjects had to see at least 9 total points in the top 4 rows (LPFT Total Score).
    • This criterion had to be met in both the Visit 1 Hour 0 (V1H0) and Visit 1 Hour 6 (V1H6) LPFT assessments.
    • There had to be ≤4 points of variance between the V1H0 and the V1H6 LPFT Eligibility Score.
    • The Marginal Reflex Distance-1 (MRD-1), the distance from the pupil center to the margin of upper lid, ≤ 2 mm (no visible pupil center defaults to 0) in the same eye
    • Visual acuity is 0.25 decimals (i.e., Snellen 20/80) or better according to standard logarithmic visual acuity chart in the same eye
  • Presence of all the following criteria at baseline:

    • Loss of reliable LPFT of ≥8 points in the top 2 rows (LPFT Eligibility Score) in the same eye; subjects had to see at least 9 total points in the top 4 rows (LPFT Total Score).
    • This criterion had to be met in the Visit 2 Hour 0 (V2H0) LPFT assessment
    • There had to be ≤4 points of variance between the V1H6 and the V2H0 LPFT Eligibility Score;
    • The MRD-1, the distance from the pupil center to the margin of upper lid, ≤ 2 mm (no visible pupil center defaults to 0) in the same eye
    • Visual acuity is 0.25 decimals (i.e., Snellen 20/80) or better according to standard logarithmic visual acuity chart in the same eye
  • Female subjects are 1-year postmenopausal, surgically sterilized, or females of childbearing potential (females who had started their menstrual cycles) with a negative urine pregnancy test at screening.

  • In either eye: Congenital ptosis; Horner syndrome; Marcus Gunn jaw-winking syndrome; Myasthenia gravis.
  • Mechanical ptosis, including ptosis due to orbital or lid tumour, cicatricial processes affecting the movements of the upper lid, and enophthalmos.
  • Previous ptosis surgery (previous blepharoplasty [only] was allowed provided the surgery took place > 3 months prior to screening).
  • Lid position affected by lid or conjunctival scarring; Visual field loss from any cause other than ptosis; History of herpes keratitis.
  • History of closed/narrow angle glaucoma (unless patent peripheral iridotomy had been performed > 3 months prior to screening).
  • Periocular neurotoxin (e.g., Botox®, Dysport®) injections within 3 months prior to screening and during the study.
  • Topical application of bimatoprost (i.e., Latisse®) to the eyelashes within 7 days prior to screening and during the study.
