NCT01123044

Brief Summary

The aim of the study is to assess if transplantation of cultivated corneal epithelial stem cells could restore vision in patients with severe ocular surface disorder with a favourable safety profile that warrants further comparative study.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or non-pregnant females between 18 and 75 years of age.
  • Written informed consent obtained from patient or parents/guardian.
  • Patients with unilateral limbal stem deficiency 2-12 months presenting with any of the following
  • Conjunctivalisation
  • Absence of limbal palisades of Vogts
  • Chronic inflammation
  • Persistent or recurrent corneal epithelial defect
  • Patients who had 2-12 months of conservative treatment. \* Diagnostic criteria for limbal stem cell deficiency are as follows:
  • Symptoms of decreased vision, redness, watering, photophobia and recurrent attacks of pain
  • Triad of signs: conjunctivalisation, neovascularisation and chronic inflammation
  • Stippled appearance of cunjunctivalised cornea with loss of palisades of Vogt
  • Recurrent and persistent epithelial defects
  • Superficial vascularisation, scarring, thick fibrovascular pannus, ulceration, melting and perforation

You may not qualify if:

  • Patients with any of the following are not eligible for enrollment into the study:
  • Pregnant or nursing woman or women of childbearing potential except if post-menopausal, surgically sterile or using accepted method(s) of birth control or having negative pregnancy test.
  • Participation in any drug trial in which the patient received an investigational drug within 30 days or 5 half-lives (whichever is longer) preceding the screening phase of this study.
  • Those persons directly involved in the conduct of the study.
  • Any history of severe infection such as hepatitis, renal, gastrointestinal, endocrine or neurological disease.
  • Evidence of corneal stromal scarring, cataract, macular oedema or scarring, retinal detachment and conjunctival keratinisation
  • Positive for HIV, Hepatitis B, C and VDRL
  • History of Pulmonary tuberculosis, hepatitis B,
  • History of alcohol or substance abuse
  • History of malignancy within previous 5 years
  • History of organ transplant
  • Any serious medical conditions or disability, which in the opinion of the investigator, would interfere with treatment or assessment or preclude completion of this study.
