Kedrion Human Plasminogen, a sterile human plasma-derived plasminogen preparation for topical ocular use will be evaluated for the indication of treatment of ligneous conjunctivitis.

KB-046 will be an open-label, historically controlled clinical trial. An estimated 10 subjects with ligneous conjunctivitis, with up to 20 affected eyes, will be treated and assessed. All 10 subjects will receive the investigational medicinal product (IMP) for 12 to 26 weeks, with a possibility for extended treatment.

Further study details as provided by Kedrion S.p.A.:

Primary Outcome Measures:
  • Number of eyes with recurrent ligneous membranes after initially showing total regression after treatment or after surgical excision. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Number of eyes with reduction of overall membrane surface area assessed by measurement of scaled photographs at study start and at the end of each 4 week cycle. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Number of subjects who experience adverse events. [ Time Frame: Up to 26 weeks. ] [ Designated as safety issue: Yes ]
  • Number of subjects who develop antibodies against human plasminogen. [ Time Frame: Up to 26 weeks. ] [ Designated as safety issue: Yes ]
  • Number of subjects who develop antibodies against bovine aprotinin. [ Time Frame: Up to 26 weeks. ] [ Designated as safety issue: Yes ]
  • Number of subjects who experience signs and symptoms of sensitization. [ Time Frame: Up to 26 weeks. ] [ Designated as safety issue: Yes ]

Intervention Details:
    Biological: Human Plasminogen
    Eye Drops

Ages Eligible for Study:   Child, Adult, Senior
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects should be diagnosed with ligneous conjunctivitis associated with Type I plasminogen deficiency, confirmed by the central laboratory and documented at pre-enrollment screening. The concomitant presence of other ligneous pseudomembranes at different sites will not constitute an exclusion criterion.
  • Subjects should have documented historical record or knowledge of lifetime disease course, including age of LC onset, history of pseudomembrane lesions, disease duration, past treatment for LC, response to treatment (including regression and recurrence) available for at least 6 months before study entrance.
  • Subjects, or their legally authorized representative, in the case of study participants < 18 years of age, should have been informed of the nature of the study, agreed to its provision, signed and dated the informed consent approved by the investigational review board (IRB) or ethics committee (EC).
  • Subjects available for the duration of the study will be included.

Exclusion Criteria:

  • Subjects presenting ligneous conjunctivitis not associated with Type 1 plasminogen deficiency.
  • Subjects with any condition which, in the opinion of the Investigator, might interfere with the evaluation of the study objectives, or participation in this trial.
  • Subjects unwilling to give written informed consent or assent to participation.
  • Subjects who have participated in another clinical trial within 1 month before study initiation, i.e. they have received any test drug within 30 days prior the study.
  • Females of childbearing potential who are either pregnant or not using an adequate method of birth
  • Females who are breastfeeding.
