Data

Animal Data

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

Section 42229-5

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.

5.2 Hypotony

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

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.

2.4 Stability

Lyophilized Mitosol® stored at 20°C to 25°C (68°F to 77°F) is stable for the shelf life indicated on the package. Avoid excessive heat. Protect from light.

Reconstituted with 1 mL of Sterile Water for Injection at a concentration of 0.2 mg/mL, mitomycin is stable for one (1) hour at room temperature.

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:

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.

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.

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.

17 Patient Counseling Information

Data

Animal Data

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

Section 42229-5 (42229-5)

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.

5.2 Hypotony

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

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.

2.4 Stability

Lyophilized Mitosol® stored at 20°C to 25°C (68°F to 77°F) is stable for the shelf life indicated on the package. Avoid excessive heat. Protect from light.

Reconstituted with 1 mL of Sterile Water for Injection at a concentration of 0.2 mg/mL, mitomycin is stable for one (1) hour at room temperature.

11 Description (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:

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.

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.

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)].

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.
