Brief Summary:
The primary objective of this trial is to assess the safety of ST266 given by non-invasive intranasal trans-cribriform delivery to subjects with ocular hypertension.

Condition or disease Intervention/treatment Phase
Ocular Hypertension Combination Product: ST266 via Intranasal Delivery Phase 1

Detailed Description:
This clinical trial is a dose escalating design in three (3) cohorts. In the first cohort, subjects will be treated with ST266 delivered using a non-invasive trans-cribriform intranasal delivery device daily for 14 days, in alternating single nostrils. If there are no SAEs and no pattern of concern in the AE's, the Investigator may proceed to the second cohort. In Cohort Two, subjects will be administered ST266 to each nostril daily for 14 days. As with the first cohort, if there are no safety concerns, the investigator may move on to the third cohort. In Cohort Three, subjects will be administered ST266 to each nostril daily for 28 days. All subjects will be followed for 12 months after the last dose of study drug. ST266 will be administered by a health care professional trained to deliver ST266 intranasally. No efficacy data will be collected.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 9 participants
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Intervention Model Description: This clinical trial is a dose escalating design in three (3) cohorts of three (3) subjects per Cohort. In the first cohort, subjects will be administered ST266, delivered intranasally, at a dose of two hundred microliters (200 µL) daily for 14 days, in alternating single nostrils. After 14 daily treatments there is a seven (7)-day follow-up period. If there are no SAEs and no pattern of concern in the AE's, the Investigator may proceed to the second cohort of three (3) subjects. In Cohort Two, three (3) subjects will be administered 200 µL to each nostril daily (400 µL total per day) for 14 days. There will be a seven (7)-day follow-up. Like Cohort One, if there are no safety concerns, the investigator may move on to the third cohort of three (3) subjects. In Cohort Three, three (3) subjects will be administered 200 µL to each nostril daily (400 µL total per day) for 28 days.

Arm Intervention/treatment
Experimental: Cohort One
Three (3) subjects, ST266 200 µL administered by trans-cribriform intranasal device once a day for 14 days using alternating sides (nostrils) with a follow-up visit at seven (7) days following End of Treatment (EOT), a follow-up call at one (1) month, and follow-up visits at three (3) months, six (6) months and 12 months following EOT.
Combination Product: ST266 via Intranasal Delivery
ST266 administered by non-invasive trans-cribriform intranasal delivery using the SipNose intranasal device.

Experimental: Cohort Two
Three (3) subjects, ST266 400 µL administered by trans-cribriform intranasal device bilaterally (200 µL/nostril) once a day for 14 days with a follow-up visit at seven (7) days following EOT, a follow-up call at one (1) month, and follow-up visits at three (3) months, six (6) months and 12 months following EOT.
Combination Product: ST266 via Intranasal Delivery
ST266 administered by non-invasive trans-cribriform intranasal delivery using the SipNose intranasal device.

Experimental: Cohort Three
Three (3) subjects, 400 µL ST266 administered by trans-cribriform intranasal device bilaterally (200 µL/nostril) once a day for 28 days with a follow-up visit at seven (7) days following EOT, a follow-up call at one (1) month, and follow-up visits at three (3) months, six (6) months and 12 months following EOT.
Combination Product: ST266 via Intranasal Delivery
ST266 administered by non-invasive trans-cribriform intranasal delivery using the SipNose intranasal device.




Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [ Time Frame: 18 months (entire duration of study) ]
    Safety will be determined by comparing the results of the screening tests at baseline and again at the end of the treatment period through the end of study. Adverse events (AEs) and Serious Adverse Events (SAEs) will be recorded. The primary safety variable is the incidence of subjects with any adverse event during the entire study.

  4. IOP ≤ 28 mmHg and at least one (1) IOP measurement > 21 mmHg.
  5. Normal visual fields (VF) both Swedish Interactive Threshold Algorithm - Short-wavelength Automated Perimetry (SITA-SWAP) and 24-2 VF spaced at least six (6) months apart.
