Study summary

This trial is studying the safety and tolerability of receiving an injection of adalimumab (Humira) during the Boston Keratoprosthesis (KPro) surgery.

Read the detailed description

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.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

What researchers measure

Primary outcomes

  1. Evaluation of Treatment Related Adverse Events.

    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

    Time frame: 30 Days

Secondary outcomes

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

    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.

    Time frame: 30 Days

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

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

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

  3. Efficacy of adalimumab Injection through incidences of Intraocular Inflammation

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

    Time frame: 30 Days

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

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

    Time frame: 30 Days

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

    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).

    Time frame: 30 Days

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 31, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
