NCT02373397

Brief Summary

The objective of this clinical study is to test the efficacy of CACICOL20® (RGTA OTR 4120) in improving wound healing and nerve regeneration in the anterior cornea, in a patient population undergoing therapeutic laser treatment for corneal dystrophy or recurrent corneal erosions.

Outcome Measures

Primary Outcomes (1)

  • Percentage recovery in subbasal nerve density.

    Degree of corneal subbasal nerve regeneration at one year postoperative, compared to preoperative level, as measured by clinical laser-scanning in vivo confocal microscopy.

    12 months postoperative

Secondary Outcomes (11)

  • Percentage recovery in subbasal nerve density.

    6 months postoperative

  • Percentage of epithelial wound closure.

    2 and 7 days postoperative.

  • Postoperative pain score on the Visual Analog Scale.

    Postoperative day 2, 7, month 6, 12

  • Corneal haze level.

    Postoperative month 6, 12

  • Number of postoperative recurrences of erosions.

    Postoperative month 12.

  • +6 more secondary outcomes

Other Outcomes (2)

  • Number of patients with adverse events as a measure of safety and tolerability.

    From operation day until 12 months postoperative.

  • Number of patients using supplementary eye treatments.

    Operation day until 12 months postoperative.

Study Arms (2)

Cacicol20

EXPERIMENTAL

Instillation of Cacicol20 eye drops after laser corneal surgery. 3 eye drops total, to be given once immediately after surgery, once 2 days after surgery, and a final time 4 days after surgery.

Device: Cacicol20

Placebo

PLACEBO COMPARATOR

Instillation of placebo eye drops (vehicle missing the active ingredient) after laser corneal surgery. 3 eye drops total, to be given once immediately after surgery, once 2 days after surgery, and a final time 4 days after surgery.

Device: Placebo

Interventions

Cacicol20DEVICE

Investigational device, regenerating agent, single-use doses, topical eye drops. Indicated for corneal wound healing.

Also known as: RGTA, Cacicol, RGTA OTR 4120

Eligibility Criteria

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

You may qualify if:

  • Signed and dated informed consent,
  • Male or female aged ≥ 18 years,
  • Patient with recurrent erosions or epithelial dystrophies indicated for treatment by phototherapeutic keratectomy of the anterior cornea

You may not qualify if:

  • In the affected eye: prior corneal surgery
  • In either eye: active ocular infection, glaucoma, or ocular hypertension
  • General history judged by the investigator to be incompatible with the study (life-threatening patient condition).
  • Known allergic hypersensitivity history to Poly(carboxyMethylGlucoseSulfate) or dextran.
  • Inability of patient to understand the study procedures and thus inability to give informed consent.
  • Participation in another clinical study within the last 3 months.
  • Already included once in this study (can only be included for one treated eye)
  • Known pregnancy (if uncertain pregnancy test will be performed)
  • Lactation
  • Women of childbearing potential without an effective method of contraception (oral contraceptive, intra-uterine device, subcutaneous contraceptive implant, vaginal ring) or women not hysterectomised, post-menopausal or surgically sterilized
