Clinical Pharmacology

CLINICAL PHARMACOLOGY Mechanism Of Action Ciprofloxacin is a fluoroquinolone antibacterial [see Microbiology]. Pharmacokinetics The plasma concentration of ciprofloxacin following bilateral administration of 0.1 Ml OTIPRIO was not measured. Microbiology Mechanism of Action The bactericidal action of ciprofloxacin results from interference with the enzyme DNA gyrase, which is needed for the synthesis of bacterial DNA. Resistance Bacterial resistance to fluoroquinolones can develop through chromosomally- or plasmidmediated mechanisms. In vitro studies demonstrated cross-resistance between ciprofloxacin and some fluoroquinolones. There is generally no cross-resistance between ciprofloxacin and other classes of antibacterial agents, such as beta-lactams or aminoglycosides. Antimicrobial Activity Ciprofloxacin has been shown to be active against most isolates of the following bacteria: Gram-positive Bacteria Staphylococcus aureus Streptococcus pneumoniae Gram-negative Bacteria Haemophilus influenzae Moraxella catarrhalis Pseudomonas aeruginosa Animal Toxicology And/Or Pharmacology Guinea pigs dosed in the middle ear with OTIPRIO exhibited no drug-related structural or functional changes of the cochlear hair cells. Clinical Studies Two randomized, multicenter, controlled clinical trials in 532 pediatric patients with bilateral otitis media with effusion undergoing myringotomy with tympanostomy tube placement evaluated the safety and efficacy of OTIPRIO when administered intra-operatively as a single dose. The median age of patients enrolled in the clinical trials was 1.5 years; 62% of patients were 6 months through 2 years of age and 38% of patients were greater than 2 years of age. The efficacy endpoint for both trials was the cumulative proportion of study treatment failures through Day 15, defined as the occurrence of any of the following events: otorrhea as determined by a blinded assessor on or after 3 days post-surgery, otic or systemic antibacterial drug use for any reason any time post-surgery, as well as patients who missed visits or were lost-to-follow-up. Table 2 presents the results from each Phase 3 trial.

Medication Guide

PATIENT INFORMATION Advise patients and their caregiver(s) that there may be drainage from the ear the first few days following ear tube surgery, but if the ear becomes painful, or continuous ear discharge is noted, or the patient develops a fever, advise patients and their caregiver(s) to consult their physician.

Overdosage & Contraindications

OVERDOSE No information provided. CONTRAINDICATIONS OTIPRIO is contraindicated in patients with a history of hypersensitivity to ciprofloxacin, to other quinolones, or to any of the components of OTIPRIO.

Side Effects & Drug Interactions

SIDE EFFECTS Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. In two randomized, sham-controlled Phase 3 clinical trials, 530 pediatric patients with bilateral otitis media with effusion undergoing tympanostomy tube placement were treated with OTIPRIO or sham administered intra-operatively as a single dose. The median age of the pediatric patients enrolled in the clinical trials was 1.5 years; 62% of patients were 6 months through 2 years of age and 38% of patients were greater than 2 years of age. Adverse reactions that occurred in at least 3% of OTIPRIO patients and at an incidence greater than sham are presented in Table 1. Table 1: Adverse Reactions in Phase 3 Trials Adverse Reactions OTIPRIO (N=357) Sham (N=173) Nasopharyngitis 5% 4% Irritability 5% 3% Rhinorrhea 3% 2% DRUG INTERACTIONS No information provided.

Warnings & Precautions

WARNINGS Included as part of the PRECAUTIONS section. PRECAUTIONS Potential For Microbial Overgrowth OTIPRIO may result in overgrowth of nonsusceptible bacteria and fungi. If such infections occur, institute alternative therapy. Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Eight in vitro mutagenicity tests have been conducted with ciprofloxacin, and the test results are listed below: Salmonella/Microsome Test (Negative) Escherichia coli DNA Repair Assay (Negative) Mouse Lymphoma Cell Forward Mutation Assay (Positive) Chinese Hamster V79 Cell HGPRT Test (Negative) Syrian Hamster Embryo Cell Transformation Assay (Negative) Saccharomyces cerevisiae Point Mutation Assay (Negative) Saccharomyces cerevisiae Mitotic Crossover and Gene Conversion Assay (Negative) Rat Hepatocyte DNA Repair Assay (Positive) Thus, 2 of the 8 in vitro tests were positive, but results of the following 3 in vivo test systems gave negative results: Rat Hepatocyte DNA Repair Assay Micronucleus Test (Mice) Dominant Lethal Test (Mice) Long-term carcinogenicity studies in mice and rats have been completed for ciprofloxacin. After daily oral doses of 750 mg/kg in mice and 250 mg/kg in rats (for mice and rats respectively, approximately 300 and 200 times the maximum recommended clinical dose of ototopical ciprofloxacin based upon body surface area, assuming total absorption of ciprofloxacin from the ear of a patient treated with OTIPRIO) were administered for up to 2 years, there was no evidence that ciprofloxacin had any carcinogenic or tumorigenic effects in these species. Fertility studies performed in rats at oral doses of ciprofloxacin up to 100 mg/kg/day revealed no evidence of impairment. This would be approximately 80 times the maximum recommended clinical dose of ototopical ciprofloxacin based upon body surface area, assuming total absorption of ciprofloxacin from the ear of a patient treated with OTIPRIO. Use In Specific Populations Pregnancy Risk Summary Animal reproduction studies have not been conducted with OTIPRIO. No adequate and wellcontrolled studies have been performed in pregnant women. Because of the negligible systemic exposure associated with clinical administration of OTIPRIO, this product is expected to be of minimal risk for maternal and fetal toxicity when administered to pregnant women. Lactation Risk Summary Ciprofloxacin is excreted in human milk with systemic administration. However, because of the negligible systemic exposure after otic application, nursing infants of mothers receiving OTIPRIO should not be affected. Pediatric Use The safety and effectiveness of OTIPRIO in infants below six months of age have not been established. The safety and effectiveness of OTIPRIO was established in 530 pediatric patients with bilateral otitis media with middle ear effusion undergoing myringotomy with tympanostomy tube placement. The median age of patients enrolled in the clinical trials was 1.5 years; 62% of patients were 6 months through 2 years of age and 38% of patients were greater than 2 years of age [see ADVERSE REACTIONS and Clinical Studies].
