Key information

About this study

This is a Phase I, Open-label, IND trial for participants undergoing a Boston Keratoprosthesis (KPro) procedure, to receive an injection of adalimumab (Humira), to study the safety and tolerability as well, to study whether there is a decrease to post surgical complications, and symptoms that participants would experience, if they did not receive the injection.

The study will recruit eight (8) participants, who will be monitored for thirty (30) days after the surgery, through eye examination and eye photos.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age 18 years or older
  • Individuals eligible for keratoprosthesis surgery, as determined by standard-of-care eligibility criteria

  • Patients with vision worse than 20/200 in the eligible eye, and contralateral eye with vision less than 20/40
  • Patients with intact nasal light projection
  • Willing and able to comply with study plan for the full duration of the study
  • Willing and able to sign a written informed consent

Exclusion criteria

  • Active tuberculosis or untreated latent tuberculosis (e.g., positive interferon-# release assay [IGRA] test, such as Quantiferon-gold)
  • Untreated active hepatitis B or C infection.
  • Ocular or periocular malignancy and/or infection
  • Inability to wear contact lens
  • Pregnancy (positive pregnancy test) or lactating
  • Participation in another interventional study at the time of screening
  • Any of the following baseline lab values
  • White blood count <3500 cells per microliter

  • Severe uncontrolled infection
  • Moderate to severe heart failure (NYHA class III/IV)
  • Active malignancy
  • History of adalimumab intolerance
  • Pregnancy or lactation
  • Medical problems or drug or alcohol dependence problems sufficient to prevent adherence to treatment and study procedures.
  • As judged by the investigator any patients that are questionable for their suitability in the study

Treatment and study plan

Adalimumab Injection

Drug

10% (4.0mg/0.04ml) dissolved in sterile saline to be injected once during the time of the Boston Keratoprosthesis (Kpro) Surgery.

Other names: Humira

Primary outcomes

  1. Evaluation of Treatment Related Adverse Events.

    Time frame: 30 Days

    To evaluate safety following subconjunctival injection of adalimumab at the time of keratoprosthesis surgery in patients who have corneal problems of such severity that they require keratoprosthesis implantation. The incidence, severity, and duration of adverse events will be assessed and documented. Because the subjects in this study have corneal problems of such severity that they require keratoprosthesis implantation, special attention will be given to adverse events of particular concern, such as microbial keratitis, subconjunctival hemorrhage, subconjunctival inflammation, or retinal necrosis or retinal detachment

Secondary outcomes

  1. Efficacy of adalimumab Injection though changes in visual acuity.

    Time frame: 30 Days

    This efficacy outcome measure will be analyzed though changes of any worsening of the best corrective visual acuity by 15 letters at every study visit.

  2. Efficacy of adalimumab Injection though changes in Optic Nerve Cup-to-Disk Ratio

    Time frame: Every Two (2) Weeks After Implantation/Injection until Day 30

    This efficacy outcome measure will be analyzed through any changes to the cup-to-disk ratio. A normal ratio is 0.2mm

  3. Efficacy of adalimumab Injection through incidences of Intraocular Inflammation

    Time frame: 30 Days

    This efficacy outcome measure will be analyzed though any incidences of intraocular inflammation that occurs post implantation/injection.

  4. Efficacy of adalimumab Injection through changes in the Ocular Coherence Tomography (OCT) of the Optic Nerves

    Time frame: 30 Days

    This efficacy outcome measure will be analyzed though any changes in the retinal nerve fiber layer thickness (nerve edema).

  5. Efficacy of adalimumab Injection though changes in the ocular coherence tomography (OCT) of the Retina

    Time frame: 30 Days

    This efficacy outcome measure will be analyzed though increases in the foveal retinal thicknesses by an increase of more than (>)100um in comparison to the previous study visit(s).
