Last verified: September 2010
The purpose of this study is to determine the way and rate that the study medication, JSM6427 a potent, highly specific integrin α5β1-antagonist is absorbed, broken-down and eliminated from the body when it is given as a single dosage strength by injection into the eye. Repeated dosages will also be given to determine the highest safe dose.

Condition Intervention Phase
Macular Degeneration Drug: JSM6427 Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1 Open Label Study to Investigate the Safety, Tolerability and Pharmacokinetic Profile of Single and Repeated Doses of JSM6427 Following Administration by Intravitreal Injection in Patients With Neovascular AMD

Further study details as provided by Jerini Ophthalmic:

Primary Outcome Measures:
  • Safety and Tolerability to determine the MTD [ Time Frame: 2 weeks after each dose ]

Secondary Outcome Measures:
  • To evaluate the systemic pharmacokinetics of JSM6427 following single and repeat doses by intravitreal injection and to assess exploratory efficacy potential of JSM6427 [ Time Frame: 1 year ]

Estimated Enrollment: 36
Study Start Date: September 2007
Study Completion Date: December 2009
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: JSM6427
    Weekly intravitreal injections for up to 4 weeks, first dose strength is one dose below the MTD. Dose strength concentrations: 1.5 mg/ml, 3 mg/ml, 7.5 mg/ml 04 15 mg/ml.
Detailed Description:
In non-clinical models, JSM6427 can lead to the inhibition and regression of choroidal neovascularization, making α5β1 an attractive target for therapeutic strategies directed at pathological angiogenesis. JSM6427 may also interfere with other key processes in the pathogenesis of AMD, namely inflammation and fibrosis. Further, non-clinical data show that JSM6427 inhibits scarring and inflammation. Thus, JSM6427 may target multiple important pathways in the pathogenesis of neovascular AMD.

Ages Eligible for Study:   50 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Best corrected visual acuity in the study eye between 5 and 7 letters inclusive using and ETDRS chart (Snellen equivalent of appx. 20/800 to 20/40.
  • Subfoveal choroidal neovascularization (CNV) due to AMD.
  • Total area of the lesion (including blood, neovascularization and scar/atrophy) must be ≤ 12 DA, of which at least 25% must be active CNV.
  • For patients with occult or non classic CNV; there must be the presence of subretinal hemorrhage (but still comprising no more than 50% of the lesion) and/or documented evidence of three or more lines of vision loss (ETDRS or equivalent) during the previous 12 weeks.
  • Clear ocular media and adequate pupillary dilatation to permit good stereo fundus photography for screening.
  • Intraocular pressure of 21 mm Hg or less.

  • Any retinovascular disease or retinal degeneration other than AMD.
  • Serous pigment epithelial detachment without the presence of neovascularization.
  • Presence of pigment epithelial tears or rips.
  • Previous posterior vitrectomy or retinal surgery.
  • Any periocular infection in the past 4 weeks.
  • Concomitant therapy with anti-VEGF therapies, e.g. Avastin, Lucentis or Macugen, or previous use of these agents within 60 days of screening in the study eye.
  • Concomitant therapy with intravenous or intravitreous corticosteroids or use within 90 days of screening.
  • Cataract surgery in the study eye within three months of screening.
  • Intraocular surgery in the study eye within three months of screening.
  • Presence of ocular infection in the study eye.
  • Presence of severe myopia (-8 diopters or greater) in the study eye.
  • Allergy to or prior significant adverse reaction to fluorescein.
  • Any major surgical procedure within one month of trial entry.
