FDA Label for Inveltys

1 Indications And Usage

INVELTYS is a corticosteroid indicated for the treatment of post-operative inflammation and pain following ocular surgery.

2 Dosage And Administration

Shake for one to two seconds before using.

Instill one to two drops of INVELTYS into the affected eye twice daily beginning the day after surgery and continuing throughout the first 2 weeks of the post-operative period.

3 Dosage Forms And Strengths

INVELTYS (loteprednol etabonate ophthalmic suspension) 1% is a sterile preserved ophthalmic suspension containing 10 mg/mL of loteprednol etabonate.

4 Contraindications

INVELTYS is contraindicated in most viral diseases of the cornea and conjunctiva including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, and varicella, and also in mycobacterial infection of the eye and fungal diseases of ocular structures.

5.1 Intraocular Pressure (Iop) Increase

Prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, as well as defects in visual acuity and fields of vision. Steroids should be used with caution in the presence of glaucoma. If this product is used for 10 days or longer, intraocular pressure should be monitored.

5.2 Cataracts

Use of corticosteroids may result in posterior subcapsular cataract formation.

5.3 Delayed Healing

Use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation. In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical steroids. The initial prescription and renewal of the medication order should be made by a physician only after examination of the patient with the aid of magnification such as slit lamp biomicroscopy and, where appropriate, fluorescein staining.

5.4 Bacterial Infections

Prolonged use of corticosteroids may suppress the host response and thus increase the hazard of secondary ocular infections. In acute purulent conditions of the eye, steroids may mask infection or enhance existing infection.

5.5 Viral Infections

Use of corticosteroid medication in the treatment of patients with a history of herpes simplex requires great caution. Use of ocular steroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex).

5.6 Fungal Infections

Fungal infections of the cornea are particularly prone to develop coincidentally with long-term local steroid application. Fungus invasion must be considered in any persistent corneal ulceration where a steroid has been used or is in use. Fungal cultures should be taken when appropriate.

5.7 Contact Lens Wear

The preservative in INVELTYS may be absorbed by soft contact lenses. Contact lenses should be removed prior to instillation of INVELTYS and may be reinserted 15 minutes following administration.

6 Adverse Reactions

Adverse reactions associated with ophthalmic steroids include elevated intraocular pressure, which may be associated with infrequent optic nerve damage, visual acuity and field defects, posterior subcapsular cataract formation, delayed wound healing and secondary ocular infection from pathogens including herpes simplex, and perforation of the globe where there is thinning of the cornea or sclera.

6.1 Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The most common adverse drug reactions in the clinical trials with INVELTYS were eye pain and posterior capsular opacification, both reported in 1% of patients. These reactions may have been the consequence of the surgical procedure.

Other

Risk Summary

INVELTYS is not absorbed systemically following topical ophthalmic administration and maternal use is not expected to result in fetal exposure to the drug.

Risk Summary

INVELTYS is not absorbed systemically by the mother following topical ophthalmic administration, and breastfeeding is not expected to result in exposure of the child to INVELTYS.

Administration

Instruct the patient to shake the bottle for one to two seconds before using.

Risk of Contamination

Advise patients not to allow the dropper tip to touch any surface, as this may contaminate the suspension.

Risk of Secondary Infection

If pain develops, or redness, itching, or inflammation becomes aggravated, the patient should be advised to consult a physician.

Contact Lens Wear

Advise patients that the preservative in INVELTYS may be absorbed by soft contact lenses. Contact lenses should be removed prior to instillation of INVELTYS and may be reinserted after 15 minutes following administration.

11 Description

Loteprednol etabonate is a corticosteroid. Its chemical name is chloromethyl 17α-[(ethoxycarbonyl)oxy]-11β-hydroxy-3-oxoandrosta-1,4-diene-17β-carboxylate. Its molecular formula is C₂₄H₃₁ClO₇ and its chemical structure is:

Chemical Structure - inveltys 01

C₂₄H₃₁ClO₇
Mol. Wt. 467.0

INVELTYS (loteprednol etabonate ophthalmic suspension) 1% contains a sterile, topical anti-inflammatory corticosteroid for ophthalmic use. Each mL contains:

• ACTIVE: loteprednol etabonate 10 mg (1%)
• INACTIVES: glycerin, sodium citrate dihydrate, Poloxamer 407, sodium chloride, edetate disodium dihydrate, citric acid, and water for injection
• PRESERVATIVE: benzalkonium chloride 0.01%

12.1 Mechanism Of Action

Corticosteroids inhibit the inflammatory response to a variety of inciting agents and probably delay or slow healing. They inhibit the edema, fibrin deposition, capillary dilation, leukocyte migration, capillary proliferation, fibroblast proliferation, deposition of collagen, and scar formation associated with inflammation. While glucocorticoids are known to bind to and activate the glucocorticoid receptor, the molecular mechanisms involved in glucocorticoid/glucocorticoid receptor-dependent modulation of inflammation are not clearly established. However, corticosteroids are thought to inhibit prostaglandin production through several independent mechanisms.

12.3 Pharmacokinetics

Loteprednol etabonate is lipid soluble and can penetrate into cells. Loteprednol etabonate is synthesized through structural modifications of prednisolone-related compounds so that it will undergo a predictable transformation to an inactive metabolite. Based upon in vivo and in vitro preclinical metabolism studies, loteprednol etabonate undergoes extensive metabolism to inactive carboxylic acid metabolites, PJ-91 and PJ-90.

Following twice-daily unilateral topical ocular dosing of INVELTYS for 14 days in healthy subjects, the plasma concentrations of loteprednol etabonate were below the limit of quantitation (1 ng/mL) at all timepoints.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

Long-term animal studies have not been conducted to evaluate the carcinogenic potential of loteprednol etabonate. Loteprednol etabonate was not genotoxic in vitro in the Ames test, the mouse lymphoma thymidine kinase (tk) assay, or in a chromosome aberration test in human lymphocytes, or in vivo in the single dose mouse micronucleus assay.

14 Clinical Studies

Clinical efficacy was evaluated in 2 multi-centered, randomized, double-masked, placebo-controlled trials in which patients with an anterior cell grade greater than or equal to "2" (a cell count of 6 or higher using a slit-lamp biomicroscope) after cataract surgery were assigned to INVELTYS or placebo (vehicle) following surgery (NCT # 02163824 and NCT # 02793817). One to two drops of INVELTYS or vehicle was self-administered twice a day for 14 days, beginning the day after surgery. Complete resolution of inflammation (a cell count of 0 maintained through day 15 without rescue medication) and complete resolution of pain (a patient-reported pain grade of 0 maintained through day 15 without rescue medication) was assessed 4, 8, and 15 days post-surgery. In the intent-to-treat analysis of both studies, a significant benefit was seen in the INVELTYS-treated group for complete resolution of ocular inflammation at Days 8 and 15, and complete resolution of pain at Days 4, 8, and 15, when compared with placebo. The consolidated clinical trial results are provided below.
