For the treatment of all stages of neurotrophic keratitis (NK)

Prescribing Information


Mechanism of Action

Cenegermin-bkbj, the active ingredient in OXERVATE®, is a recombinant form of human nerve growth factor (rhNGF)1

NGF is an endogenous protein involved in the differentiation and maintenance of neurons, which acts through specific high-affinity (ie, TrkA) and low-affinity (ie, p75NTR) nerve growth factor receptors in the anterior segment of the eye to support corneal innervation and integrity1


Endogenous NGF

Cenegermin-bkbj is structurally identical to human NGF protein made in ocular tissues.5

How NGF Works

NGF and the ocular surface

Endogenous NGF supports corneal integrity through 3 mechanisms contributing to ocular surface homeostasis (shown in preclinical models)1,2,6:

  • Corneal innervation
  • Tear secretion
  • Epithelial cell growth

As part of ocular surface homeostasis, corneal epithelial cells produce NGF to support sensory nerve health, and sensory nerves produce neuromediators to support corneal epithelial cell health.2

Important Safety Information


Use with Contact Lens
Contact lenses should be removed before applying OXERVATE because the presence of a contact lens (either therapeutic or corrective) could theoretically limit the distribution of cenegermin-bkbj onto the area of the corneal lesion. Lenses may be reinserted 15 minutes after administration.

Eye Discomfort
OXERVATE may cause mild to moderate eye discomfort such as eye pain during treatment. The patient should be advised to contact their doctor if a more serious eye reaction occurs.


In clinical trials, the most common adverse reaction was eye pain following instillation which was reported in approximately 16% of patients. Eye pain may arise as corneal healing occurs. Other adverse reactions occurring in 1% to 10% of OXERVATE patients included corneal deposits, foreign body sensation, ocular hyperemia, ocular inflammation, photophobia, tearing, and headache.


There are no data from the use of OXERVATE in pregnant women to inform any drug associated risks.

The developmental and health benefits of breastfeeding should be considered, along with the mother’s clinical need for OXERVATE, and any potential adverse effects on the breastfed infant from OXERVATE.

Pediatric Use
The safety and effectiveness of OXERVATE have been established in the pediatric population. Use of OXERVATE in pediatric patients 2 years of age and older is supported by evidence from adequate and well-controlled trials of OXERVATE in adults with additional safety data in children.


OXERVATE® (cenegermin-bkbj) ophthalmic solution 0.002% (‍20 mcg/mL) is indicated for the treatment of neurotrophic keratitis.


Instill one drop of OXERVATE in the affected eye(s), 6 times a day at 2‑hour intervals for eight weeks.

To report ADVERSE REACTIONS, contact Dompé U.S. Inc. at 1-833-366-7387 or FDA at 1-800-FDA-1088 or
