Each mL of reconstituted solution contains 0.2 mg mitomycin and has a pH between 5.0 and 8.0.

  • 4 CONTRAINDICATIONS

    4.1 Hypersensitivity

    Mitosol® is contraindicated in patients that have demonstrated a hypersensitivity to mitomycin in the past.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Cell Death

    Mitomycin is cytotoxic. Use of mitomycin in concentrations higher than 0.2 mg/mL or use for longer than 2 minutes may lead to unintended corneal and/or scleral damage including thinning or perforation. Direct contact with the corneal endothelium will result in cell death.

    5.2 Hypotony

    The use of mitomycin has been associated with an increased incidence of post-operative hypotony.

    5.3 Cataract Formation

    Use in phakic patients has been correlated to a higher incidence of lenticular change and cataract formation.

    5.4 Embryo-Fetal Toxicity

    Based on findings in animals and mechanism of action, Mitosol® can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, parenteral administration of mitomycin resulted in teratogenicity [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)].

  • 6 ADVERSE REACTIONS

    The following clinically significant adverse reactions are described elsewhere in the labeling:

    Cell Death [see Warnings and Precautions (5.1)]
    Hypotony [see Warnings and Precautions (5.2)]
    Cataract Formation [see Warnings and Precautions (5.3)]

    6.1 Ophthalmic Adverse Reactions

    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 frequent adverse reactions to Mitosol® occur locally, as an extension of the pharmacological activity of the drug. These reactions include:

    Blebitis: bleb ulceration, chronic bleb leak, encapsulated/cystic bleb, bleb-related infection, wound dehiscence, conjunctival necrosis, thin-walled bleb

    Cornea: corneal endothelial damage, epithelial defect, anterior synechiae, superficial punctuate keratitis, Descemet's detachment, induced astigmatism

    Endophthalmitis

    Hypotony: choroidal reactions (choroidal detachment, choroidal effusion, serous choroidal detachment, suprachoroidal hemorrhage, hypotony maculopathy, presence of supraciliochoroidal fluid, hypoechogenic suprachoroidal effusion)

    Inflammation: iritis, fibrin reaction

    Lens: cataract development, cataract progression, capsule opacification, capsular constriction and/or capsulotomy rupture, posterior synechiae

    Retina: retinal pigment epithelial tear, retinal detachment (serous and rhegatogenous)

    Scleritis: wound dehiscence

    Vascular: hyphema, central retinal vein occlusion, hemiretinal vein occlusion, retinal hemorrhage, vitreal hemorrhage and blood clot, subconjunctival hemorrhage, disk hemorrhage

    Additional Reactions: macular edema, sclera thinning or ulceration, intraocular lens capture, disk swelling, malignant glaucoma, lacrimal drainage system obstruction, ciliary block, corneal vascularization, visual acuity decrease, cystic conjunctival degeneration, upper eyelid retraction, dislocated implants, severe loss of vision.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on findings in animals and mechanism of action [see Clinical Pharmacology (12.1)], Mitosol® can cause fetal harm when administered to a pregnant woman. There are no available data on Mitosol® use in pregnant women to inform the drug-associated risk. In animal reproduction studies, parenteral administration of mitomycin resulted in teratogenicity (see Data). Advise pregnant women of the potential risk to a fetus.

    The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% - 4% and 15% - 20%, respectively.

    Data

    Animal Data

    Parenteral administration of mitomycin in animal reproduction studies produced fetal malformations and embryofetal lethality.

    8.2 Lactation

    Risk Summary

    There are no data on the presence of mitomycin in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during and for 1 week following administration of Mitosol®.

    8.3 Females and Males of Reproductive Potential

    Mitosol® can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)].

    Pregnancy Testing

    Verify pregnancy status in females of reproductive potential prior to using Mitosol®.

    8.4 Pediatric Use

    Safety and effectiveness in pediatric patients have not been established.

    8.5 Geriatric Use

    No overall differences in safety and effectiveness have been observed between elderly and younger patients.

  • 11 DESCRIPTION

    Mitomycin is an antibiotic isolated from the broth of Streptomyces verticillus Yingtanensis which has been shown to have antimetabolic activity.

    Mitomycin is a blue-violet crystalline powder with the molecular formula of C15H18N4O5 and a molecular weight of 334.33. Its chemical name is 7-amino-9α-methoxymitosane and it has the following structural formula:

    Structural Formula

    Mitosol® is a sterile lyophilized mixture of mitomycin and mannitol, which, when reconstituted with Sterile Water for Injection, provides a solution for application in glaucoma filtration surgery. Mitosol® is supplied in vials containing 0.2 mg of mitomycin. Each vial also contains mannitol 0.4 mg, at a 1:2 ratio of mitomycin to mannitol. Each mL of reconstituted solution contains 0.2 mg mitomycin and has a pH between 5.0 and 8.0.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Mitosol® inhibits the synthesis of deoxyribonucleic acid (DNA). The guanine and cytosine content correlates with the degree of mitomycin-induced cross-linking. Cellular RNA and protein synthesis may also be suppressed.

    12.3 Pharmacokinetics

    Absorption

    The systemic exposure of mitomycin following ocular administration of Mitosol® in humans is unknown. Based on a comparison of the proposed dose of up to 0.2 mg to intravenous (IV) doses of mitomycin used clinically for treatment of oncologic indications (up to 20 mg/m2), systemic concentrations in humans upon ocular administration are expected to be multiple orders of magnitude lower than those achieved by IV administration.

    Elimination

    Metabolism

    In humans, mitomycin is cleared from ophthalmic tissue after intraoperative topical application and irrigation, as metabolism occurs in other affected tissues. Systemic clearance is affected primarily by metabolism in the liver. The rate of clearance is inversely proportional to the maximal serum concentration because of saturation of the degradative pathways.

    Excretion

    Approximately 10% of an injectable dose of mitomycin is excreted unchanged in the urine. Since metabolic pathways are saturated at relatively low doses, the percent of a dose excreted in urine increases.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Adequate long-term studies in animals to evaluate carcinogenic potential have not been conducted with Mitosol®. Intravenous administration of mitomycin has been found to be carcinogenic in rats and mice. At doses approximating the recommended clinical injectable dose in humans, mitomycin produces a greater than 100 percent increase in tumor incidence in male Sprague-Dawley rats, and a greater than 50 percent increase in tumor incidence in female Swiss mice.

    The effect of Mitosol® on fertility is unknown.

  • 14 CLINICAL STUDIES

    In placebo-controlled studies reported in the medical literature, mitomycin reduced intraocular pressure (IOP) by 3 mmHg in patients with open-angle glaucoma when used as an adjunct to ab externo glaucoma surgery by Month 12.

    In studies with a historical control reported in the medical literature, mitomycin reduced intraocular pressure (IOP) by 5 mmHg in patients with open-angle glaucoma when used as an adjunct to ab externo glaucoma surgery by Month 12.
