• 1 other identifier: ST266-IOPHTN-101
• Study Type: interventional
• Target: 9
• Locations: 1 country

Brief Summary

The primary objective of this trial is to assess the safety of ST266 given by non-invasive intranasal trans-cribriform delivery to glaucoma suspect subjects with ocular hypertension, optic nerve cupping, or family history of glaucoma.

Conditions

Ocular Hypertension

Outcome Measures

Primary Outcomes (1)

• Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]

  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.

  18 months (entire duration of study)

Study Arms (3)

Cohort One

EXPERIMENTAL

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.

Cohort Two

EXPERIMENTAL

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.

Cohort Three

EXPERIMENTAL

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.

Eligibility Criteria

• Age: 20 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Signed Informed Consent Form and HIPAA (Health Insurance Portability and Accountability Act) document.
• Male or Female, Ages 20-75 years.
• Must be clinically followed as a glaucoma suspect without evidence of glaucomatous damage.
• Must have one of the following: 1) IOP ≤ 28 mmHg and at least one (1) IOP measurement \> 21 mmHg, or 2) physiologic cupping of the optic nerve, or 3) a family history of glaucoma.
• Two (2) normal visual fields (VF) both Swedish Interactive Threshold Algorithm - Short-wavelength Automated Perimetry (SITA-SWAP) and 24-2 VF prior to subject enrollment at the Baseline Visit.
• Two (2) normal Ocular Coherence Tomography (OCT) (of macula and nerve fiber layer) prior to subject enrollment at the Baseline Visit.
• Gonioscopy open to at least scleral spur with normal iris configuration.
• Normal baseline neuro-cognitive testing.
• Normal baseline Magnetic Resonance Imaging (MRI), including expected age-related changes, performed with and without contrast.
• Cohort Three group only: Baseline Lumbar Puncture within normal limits.

You may not qualify if:

• Females of Child Bearing Potential (FOCBP) who are pregnant or lactating or who will not abstain from sexual activity for 14 days prior to Visit 1, and willing to remain so through 30 days following completion of the subject's first menstrual cycle following the End of Treatment (EOT) Visit. Alternatively, a WOCBP who will not remain abstinent must have been using one of the following acceptable methods of birth control for the times specified:
• IUD in place for at least three (3) months prior to Visit 1 until completion of the subject's first menstrual cycle following the EOT Visit.
• Barrier method (condom or diaphragm) with spermicide for at least three (3) months prior to Visit 1 through completion of the subject's first menstrual cycle following the EOT Visit.
• Stable hormonal contraceptive for at least three (3) months prior to Visit 1 through completion of the subject's first menstrual cycle following the EOT Visit. NOTE: For Depo-Provera injection contraceptives, the statement regarding first menstrual cycle following administration of the study product is not applicable as females receiving this form of contraception will not have menses.
• In a monogamous relationship with a surgically sterilized (i.e., vasectomized) partner at least six (6) months prior to Visit 1.
• Have undergone one of the following sterilization procedures at least six (6) months prior to Visit 1: Bilateral tubal ligation, Hysterectomy, Hysterectomy with unilateral or bilateral oophorectomy, Bilateral oophorectomy.
• Unwillingness to submit a urine pregnancy test at screening if of childbearing potential.
• Male subjects who refuse to use one of the following birth control methods:
• Abstinence from the time of consent and through the duration of their participation in the protocol
• Barrier method (condom or diaphragm) with spermicide from time of consent through the duration of their participation in the protocol
• Surgical sterilization (vasectomy) at least 6 months prior to consent.
• IOP greater than 29 mmHg in either eye.
• Patients with high risk factors of ocular hypertension, such as thin central corneas, as identified by the Principal Investigator who may benefit from earlier treatment will be excluded.
• Evidence of Angle closure.
• Recent laser or incisional glaucoma surgery.

Model Details: 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.
