|blackBoxWarningTitle=Warning: Liver injury
|blackBoxWarningBody=Trovafloxacin mesylate has been associated with serious liver injury leading to liver transplantation and/or death. Trovafloxacin mesylate-associated liver injury have been reported with both short-term and long.term drug exposure. Trovafloxacin use exceeding 2 weeks in duration is associated with a significantly increased risk of serious liver injury. Liver injury has also been reported following trovafloxacin re-exposure. Trovafloxacin should be reserved for use in patients with serious, life or limb-threatening infections who receive their initial therapy in an in-patient health care facility (I.E., Hospotal or long-term nursing care facility). Trovafloxacin should not be used when safer, alternative antimicrobial therapy will be effective.

Non–Guideline-Supported Use

There is limited information regarding Off-Label Non–Guideline-Supported Use of Trovafloxacin mesylate in pediatric patients.

Contraindications

Trovafloxacin mesylate is contraindicated in persons with a history of hypersensitivity to trovafloxacin, alatrofloxacin, quinolone antimicrobial agents or any other components of these products.

Warnings

  • Trovafloxacin mesylate-associated liver enzyme abnormalities, symptomatic hepatitis, jaundice and liver failure (including rare reports of acute hepatic necrosis with eosinophilic infiltration, liver transplantation and/or death) have been reported with both short-term and long-term drug exposure in men and women. Trovafloxacin use exceeding 2 weeks in duration is associated with a significantly increased risk of serious liver injury. Liver injury has also benn reportes following trovafloxacin re-exposure. clinicians should monitor liver function test (e.g., AST, ALT, bilirubin) in trovafloxacin recipients who develop signs or symptoms consistent with hepatitis. Clinicians should consider discontinuing travofloxacin in those patients who develop liver function test abnormalities.
  • The safety and effectiveness of trovafloxacin in pediatric patients and adolescents less than 18 years age, pregnant women, and nursing women have not been established.
  • As with other members of the quinolone class, trovafloxacin has caused arthropathy and/or chondrodysplasia in immature rats and dogs. The significance of these findings to humans is unknown.
  • Convulsions, increased intracranial pressure and psychosis have been reported in patients receiving quinolones. Quinolones may also cause central nervous system stimulation which may lead to tremors, restlessness, lightheadedness, confusion, hallucinations, paranoia, depression, nightmares and insomnia. These reactions may occur following the first dose. If these reactions occur in patients receiving trovafloxacin or alatrofloxacin, the drug should be discontinued and appropriate measures instituted.
  • As with other quinolones, trovafloxacin mesylate should be used with caution in patients with known or suspected CNS disorders, such as severe cerebral atherosclerosis, epilepsy, and other factors that predispose to seizures.
  • Life-threatening hypotension has been reported with alatrofloxacin administration. This has occurred in patients receiving alatrofloxacin at either the recommended rate of infusion or if given more rapidly. Hypotension may be potentiated with the concomitant administration of anesthetic agents. Alatrofloxacin should only be administered by slow intravenous infusion over a period of 60 minutes. Blood pressure should be monitored closely during infusion.
  • Trovafloxacin mesylate should be discontinued at the first appearance of a skin rash or any other sign of hypersensitivity. Serious acute hypersensitivity reactions may require treatment with epinephrine and other resuscitative measures, including oxygen, intravenous fluids, antihistamines, corticosteroids, pressor amines and airway management, as clinically indicated.
  • Pseudomembranous colitis has been reported with nearly all antibacterial agents, including trovafloxacin mesylate, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of any antibacterial agent.
  • Treatment with antibacterial agents alters the flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is the primary cause of "antibiotic-associated colitis."
  • After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against C. difficile colitis.
  • Although not seen in trovafloxacin mesylate clinical trials, ruptures of the shoulder, hand, and Achilles tendons that required surgical repair or resulted in prolonged disability have been reported in patients receiving quinolones. trovafloxacin mesylate should be discontinued if the patient experiences pain, inflammation or rupture of a tendon. Patients should rest and refrain from exercise until the diagnosis of tendinitis or tendon rupture has been confidently excluded. Tendon rupture can occur during or after therapy with quinolones.
  • Trovafloxacin has not been shown to be effective in the treatment of syphilis. Antimicrobial agents used in high doses for short periods of time to treat gonorrhea may mask or delay the symptoms of incubating syphilis. All patients with gonorrhea should have a serologic test for syphilis at the time of diagnosis.

Adverse Reactions

Clinical Trials Experience

Over 6000 patients have been treated with trovafloxacin mesylate in multidose clinical efficacy trials worldwide.

In trovafloxacin mesylate studies the majority of adverse reactions were described as mild in nature (over 90% were described as mild or moderate). Trovafloxacin mesylate was discontinued for adverse events thought related to drug in 5% of patients (dizziness 2.4%, nausea 1.9%, headache 1.1%, and vomiting 1.0%).

Dizziness/lightheadedness on trovafloxacin mesylate is generally mild, lasts for a few hours following a dose, and in most cases, resolves with continued dosing. The incidence of dizziness and lightheadedness in trovafloxacin mesylate patients over 65 years is 3.1% and 0.6%, respectively.

trovafloxacin mesylate appears to have a low potential for phototoxicity. In clinical trials with trovafloxacin mesylate, only mild, treatment-related phototoxicity was observed in less than 0.03% (2/7096) of patients.

Additional reported drug-related events in clinical trials (remotely, possibly, probably or unknown) that occurred in <1% of trovafloxacin mesylate-treated patients are:

The incidence and magnitude of liver function abnormalities with trovafloxacin mesylate were the same as comparator agents except in the only study in which oral trovafloxacin mesylate was administered for 28 days. In this study (chronic bacterial prostatitis) nine percent (13/140) of trovafloxacin mesylate-treated patients experienced elevations of serum transaminases (AST and/or ALT) of ≥3 times the upper limit of normal. These liver function test abnormalities generally developed at the end of, or following completion of, the planned 28-day course of therapy, but were not associated with concurrent elevations of related laboratory measures of hepatic function (such as serum bilirubin, alkaline phosphatase, or lactate dehydrogenase). Patients were asymptomatic with these abnormalities, which generally returned to normal within 1–2 months after discontinuation of therapy.

Postmarketing Experience

Adverse reactions reported with trovafloxacin mesylate during the post-marketing period include:

Drug Interactions

  • Antacids, Sucralfate, and Iron: The absorption of oral trovafloxacin is significantly reduced by the concomitant administration of some antacids containing magnesium or aluminum, citric acid/sodium citrate (Bicitra®), as well as sucralfate and iron (ferrous ions). These agents as well as formulations containing divalent and trivalent cations such as Videx®, (Didanosine), chewable/buffered tablets or the pediatric powder for oral solution, should be taken at least 2 hours before or 2 hours after oral trovafloxacin administration.
  • Morphine: Co-administration of intravenous morphine significantly reduces the absorption of oral trovafloxacin. Intravenous morphine should be administered at least 2 hours after oral trovafloxacin mesylate dosing in the fasted state and at least 4 hours after oral trovafloxacin mesylate is taken with food. Trovafloxacin administration had no effect on the pharmacokinetics of morphine or its metabolite, morphine-6-β-glucuronide.
  • Warfarin: There have been reports during the post-marketing experience that trovafloxacin/alatrofloxacin enhance the effects of warfarin, including cases of bleeding. The mechanism for this reaction is unknown. Prothrombin time, International Normalized Ratio (INR) or other suitable anticoagulation tests should be closely monitored if trovafloxacin/alatrofloxacin is administered concomitantly with warfarin. Patients should also be monitored for evidence of bleeding.
  • Minor pharmacokinetic interactions without clinical significance have been observed with co-administration of trovafloxacin mesylate Tablets with caffeine, omeprazole and calcium carbonate.
  • No significant pharmacokinetic interactions with theophylline, cimetidine, digoxin, warfarin, or cyclosporine have been observed with trovafloxacin mesylate Tablets.
  • Alatrofloxacin should not be co-administered with any solution containing multivalent cations, e.g., magnesium, through the same intravenous line.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): C An increase in skeletal variations was observed in rat fetuses after daily oral 75 mg/kg maternal doses of trovafloxacin (approximately 15 times the highest recommended human dose based on mg/kg or 2 times based upon body surface area) were administered during organogenesis. However, fetal skeletal variations were not observed in rats dosed orally with 15 mg/kg trovafloxacin. Evidence of fetotoxicity (increased perinatal mortality and decreased body weights) was also observed in rats at 75 mg/kg. Daily oral doses of trovafloxacin at 45 mg/kg (approximately 9 times the highest recommended human dose based on mg/kg or 2.7 times based upon body surface area) in the rabbit were not associated with an increased incidence of fetal skeletal variations or malformations.

An increase in skeletal variations and malformations was observed in rat fetuses after daily intravenous doses of alatrofloxacin at ≥20 mg/kg/day (approximately 4 times the highest recommended human dose based on mg/kg or 0.6 times based upon body surface area) were administered to dams during organogenesis. In the rabbit, an increase in fetal skeletal malformations was also observed when 20 mg/kg/day (approximately equal to the highest recommended human dose based upon body surface area) of alatrofloxacin was given intravenously during the period of organogenesis. Intravenous dosing of alatrofloxacin at 6.5 mg/kg in the rat or rabbit was not associated with an increased incidence of skeletal variations or malformations. Fetotoxicity and fetal skeletal malformations have been associated with other quinolones.

Oral doses of trovafloxacin >5mg/kg were associated with an increased gestation time in rats, and several dams at 75 mg/kg experienced uterine dystocia.

There are no adequate and well-controlled studies in pregnant women. trovafloxacin mesylate should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Trovafloxacin mesylate in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Trovafloxacin mesylate during labor and delivery.

Nursing Mothers

Trovafloxacin is excreted in human milk and was found in measurable concentrations in the breast milk of lactating subjects.

Because of the potential for unknown effects from trovafloxacin in nursing infants from mothers taking trovafloxacin, a decision should be made either to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use

The safety and effectiveness of trovafloxacin in pediatric patients and adolescents less than 18 years of age have not been established. Quinolones, including trovafloxacin, cause arthropathy and osteochondrosis in juvenile animals of several species.

Geriatic Use

In multiple-dose clinical trials of trovafloxacin, 27% of patients were ≥65 years of age and 12% of patients were ≥75 years of age. The overall incidence of drug-related adverse reactions, including central nervous system and gastrointestinal side effects, was less in the ≥65 year group than the other age groups.

Gender

There are no significant differences in trovafloxacin pharmacokinetics between males and females when differences in body weight are taken into account. After single 200 mg doses, trovafloxacin Cmax and AUC(0–∞) were 60% and 32% higher, respectively, in healthy females compared to healthy males. Following repeated daily administration of 200 mg for 7 days, the Cmax for trovafloxacin was 38% higher and AUC(0–24) was 16% higher in healthy females compared to healthy males. The clinical importance of the increases in serum levels of trovafloxacin in females has not been established.

Race

There is no FDA guidance on the use of Trovafloxacin mesylate with respect to specific racial populations.

Renal Impairment

The pharmacokinetics of trovafloxacin are not affected by renal impairment. Trovafloxacin serum concentrations are not significantly altered in subjects with severe renal insufficiency (creatinine clearance <20 mL/min), including patients on hemodialysis.

Hepatic Impairment

Following repeated administration of 100 mg for 7 days to patients with mild cirrhosis (Child-Pugh Class A), the AUC(0–24) for trovafloxacin was increased ~45% compared to matched controls. Repeated administration of 200 mg for 7 days to patients with moderate cirrhosis (Child-Pugh Class B) resulted in an increase of ~50% in AUC(0–24) compared to matched controls. There appeared to be no significant effect on trovafloxacin Cmax for either group. The oral clearance of trovafloxacin was reduced ~30% in both cirrhosis groups, which corresponded to prolongation of half life by 2–2.5 hours (25–30% increase) compared to controls. There are no data in patients with severe cirrhosis (Child-Pugh Class C). Dosage adjustment is recommended in patients with mild to moderate cirrhosis.

Females of Reproductive Potential and Males

Trovafloxacin and alatrofloxacin did not affect the fertility of male or female rats at oral and I.V. doses of 75 mg/kg/day and 50 mg/kg/day, respectively. These doses are 15 and 10 times the recommended maximum human dose based on mg/kg or approximately 2 times based on mg/m2. However, oral doses of trovafloxacin at 200 mg/kg/day (40 times the recommended maximum human dose based on mg/kg or about 6 times based on mg/m2) were associated with increased preimplantation loss in rats.

Immunocompromised Patients

There is no FDA guidance one the use of Trovafloxacin mesylate in patients who are immunocompromised.

Photosensitivity Potential

In a study of the skin response to ultraviolet and visible radiation conducted in 48 healthy volunteers (12 per group), the minimum erythematous dose (MED) was measured for ciprofloxacin, lomefloxacin, trovafloxacin and placebo before and after drug administration for 5 days. In this study, trovafloxacin (200 mg q.d.) was shown to have a lower potential for producing delayed photosensitivity skin reactions than ciprofloxacin (500 mg b.i.d.) or lomefloxacin (400 mg q.d.), although greater than placebo.

Administration and Monitoring

Administration

  • Oral
  • Intravenous

Monitoring

There is limited information regarding Trovafloxacin mesylate Monitoring in the drug label.

IV Compatibility

There is limited information regarding the compatibility of Trovafloxacin mesylate and IV administrations.

Overdosage

Trovafloxacin has a low order of acute toxicity. The minimum lethal oral dose in mice and rats was 2000 mg/kg or greater. The minimum lethal I.V. dose for the prodrug, alatrofloxacin, was 50–125 mg/kg for mice and greater than 75 mg/kg for rats. Clinical signs observed included decreased activity and respiration, ataxia, ptosis, tremors and convulsions.

In the event of acute oral overdosage, the stomach should be emptied by inducing vomiting or by gastric lavage. The patient should be carefully observed and given symptomatic and supportive treatment. Adequate hydration should be maintained. Trovafloxacin is not efficiently removed from the body by hemodialysis.

Mechanism of Action

Trovafloxacin is a fluoronaphthyridone related to the fluoroquinolones with in vitro activity against a wide range of gram-negative and gram-positive aerobic, and anaerobic microorganisms. The bactericidal action of trovafloxacin results from inhibition of DNA gyrase and topoisomerase IV. DNA gyrase is an essential enzyme that is involved in the replication, transcription and repair of bacterial DNA. Topoisomerase IV is an enzyme known to play a key role in the partitioning of the chromosomal DNA during bacterial cell division. Mechanism of action of fluoroquinolones including trovafloxacin is different from that of penicillins, cephalosporins, aminoglycosides, macrolides, and tetracyclines. Therefore, fluoroquinolones may be active against pathogens that are resistant to these antibiotics. There is no cross-resistance between trovafloxacin and the mentioned classes of antibiotics. The overall results obtained from in vitro synergy studies, testing combinations of trovafloxacin with beta-lactams and aminoglycosides, indicate that synergy is strain specific and not commonly encountered. This agrees with results obtained previously with other fluoroquinolones. Resistance to trovafloxacin in vitro develops slowly via multiple-step mutation in a manner similar to other fluoroquinolones. Resistance to trovafloxacin in vitro occurs at a general frequency of between 1×10-7 to 10-10. Although cross-resistance has been observed between trovafloxacin and some other fluoroquinolones, some microorganisms resistant to other fluoroquinolones may be susceptible to trovafloxacin.

Structure

The chemical structure is:

Pharmacodynamics

There is limited information regarding Trovafloxacin mesylate Pharmacodynamics in the drug label.

Pharmacokinetics

After intravenous administration, alatrofloxacin is rapidly converted to trovafloxacin. Plasma concentrations of alatrofloxacin are below quantifiable levels within 5 to 10 minutes of completion of a 1 hour infusion.

Absorption

Trovafloxacin is well-absorbed from the gastrointestinal tract after oral administration. The absolute bioavailability is approximately 88%. For comparable dosages, no dosage adjustment is necessary when switching from parenteral to oral administration.

Figure 1. Mean trovafloxacin serum concentrations determined following 1 hour intravenous infusions of alatrofloxacin at daily doses of 200 mg (trovafloxacin equivalents) to healthy male volunteers and following daily oral administration of 200 mg trovafloxacin for 7 days to six male and six female healthy young volunteers.

Pharmacokinetics Parameters

The mean pharmacokinetic parameters (±SD) of trovafloxacin after single and multiple 100 mg and 200 mg oral doses and 1 hour intravenous infusions of alatrofloxacin in doses of 200 and 300 mg (trovafloxacin equivalents) appear in the chart below.

Serum concentrations of trovafloxacin are dose proportional after oral administration of trovafloxacin in the dose range of 30 to 1000 mg or after intravenous administration of alatrofloxacin in the dose range of 30 to 400 mg (trovafloxacin equivalents). Steady state concentrations are achieved by the third daily oral or intravenous dose of trovafloxacin with an accumulation factor of approximately 1.3 times the single dose concentrations.

Oral absorption of trovafloxacin is not altered by concomitant food intake; therefore, it can be administered without regard to food.

The systemic exposure to trovafloxacin (AUC0–∞) administered as crushed tablets via nasogastric tube into the stomach was identical to that of orally administered intact tablets. Administration of concurrent enteral feeding solutions had no effect on the absorption of trovafloxacin given via nasogastric tube into the stomach. When trovafloxacin was administered as crushed tablets into the duodenum via nasogastric tube, the AUC0–∞ and peak serum concentration (Cmax) were reduced by 30% relative to the orally administered intact tablets. Time to peak serum level (Tmax) was also decreased from 1.7 hrs to 1.1 hrs.

Distribution

The mean plasma protein bound fraction is approximately 76%, and is concentration-independent. Trovafloxacin is widely distributed throughout the body. Rapid distribution of trovafloxacin into tissues results in significantly higher trovafloxacin concentrations in most target tissues than in plasma or serum.

Presence in Breast Milk

Trovafloxacin was found in measurable concentrations in the breast milk of three lactating subjects. The average measurable breast milk concentration was 0.8 µg/mL (range: 0.3–2.1 µg/mL) after single I.V. alatrofloxacin (300 mg trovafloxacin equivalents) and repeated oral trovafloxacin (200 mg) doses.

Metabolism

Trovafloxacin is metabolized by conjugation (the role of cytochrome P450 oxidative metabolism of trovafloxacin is minimal). Thirteen percent of the administered dose appears in the urine in the form of the ester glucuronide and 9% appears in the feces as the N-acetyl metabolite (2.5% of the dose is found in the serum as the active N-acetyl metabolite). Other minor metabolites (diacid, sulfamate, hydroxycarboxylic acid) have been identified in both urine and feces in small amounts (<4% of the administered dose).

Excretion

Approximately 50% of an oral dose is excreted unchanged (43% in the feces and 6% in the urine).

After multiple 200 mg doses, to healthy subjects, mean (±SD) cumulative urinary trovafloxacin concentrations were 12.1±3.4 µg/mL. With these levels of trovafloxacin in urine, crystals of trovafloxacin have not been observed in the urine of human subjects.

Nonclinical Toxicology

Carcinogenesis and Mutagenesis

Long term studies in animals to determine the carcinogenic potential of trovafloxacin or alatrofloxacin have not been conducted.

trovafloxacin mesylate did not shorten the time to development of UV-induced skin tumors in hairless albino (Skh-1) mice; thus, it was not photo co-carcinogenic in this model. These mice received oral trovafloxacin and concurrent irradiation with simulated sunlight 5 days per week for 40 weeks followed by a 12-week treatment-free observation period. The daily dose of UV radiation used in this study was approximately 30% of the minimal dose of UV radiation that would induce erythema in Caucasian humans. The median time to the development of skin tumors in the hairless mice (42–43 weeks) was similar in the vehicle control group and those given 10 or 30 mg/kg of trovafloxacin daily. At a dose level of 30 mg/kg/day, the mice had skin trovafloxacin concentrations of approximately 7 µg/g. Following multiple 200 mg daily doses of trovafloxacin, the amount in human skin is estimated to be about 3 µg/g, based upon plasma concentrations measured at this dose level.

Trovafloxacin was not mutagenic in the Ames Salmonella reversion assay or CHO/HGPRT mammalian cell gene mutation assay and it was not clastogenic in mitogen-stimulated human lymphocytes or mouse bone marrow cells. A mouse micronucleus test conducted with alatrofloxacin was also negative. The positive response observed in the E. coli bacterial mutagenicity assay may be due to the inhibition of DNA gyrase by trovafloxacin.

Animal Pharmacology
  • Quinolones have been shown to cause arthropathy in immature animals.
  • Arthropathy and chondrodysplasia were observed in immature animals given trovafloxacin.
  • At doses from 10 to 15 times the human dose based on mg/kg or approximately 3 to 5 times based on mg/m2, trovafloxacin has been shown to cause arthropathy in immature rats and dogs. In addition, these drugs are associated with an increased incidence of chondrodysplasia in rats compared to controls. There is no evidence of arthropathies in fully mature rats and dogs at doses from 40 or 10 times the human dose based on mg/kg or approximately 5 times based on mg/m2 for a 6 month exposure period.
  • Unlike some other members of the quinolone class, crystalluria and ocular toxicity were not observed in chronic safety studies with rats or dogs with either trovafloxacin or its prodrug, alatrofloxacin.
  • Quinolones have been reported to have proconvulsant activity that is exacerbated with concomitant use of non-steroidal anti-inflammatory drugs (NSAIDS). Neither trovafloxacin administered orally at 500 mg/kg, nor alatrofloxacin administered intravenously at 75 mg/kg, showed an increase in measures of seizure activity in mice at doses when used in combination with the active metabolite of the NSAID, fenbufen.
  • As with other members of the quinolone class, trovafloxacin at doses 5 to 10 times the human dose based on mg/kg or 1 to 5 times the human dose based on mg/m2 produces testicular degeneration in rats and dogs dosed for 6 months.
  • At a dose of trovafloxacin 10 times the highest human dose based on mg/kg or approximately 5 times based on mg/m2, elevated liver enzyme levels which correlated with centrilobular hepatocellular vacuolar degeneration and necrosis were observed in dogs in a 6 month study. A subsequent study demonstrated reversibility of these effects when trovafloxacin was discontinued.

Clinical Studies

Hospitalized Community Acquired Pneumonia

Adult patients with clinically and radiologically documented community acquired pneumonia, requiring hospitalization and initial intravenous therapy, participated in two randomized, multicenter, double-blind, double-dummy trials. The first trial compared intravenous alatrofloxacin (200 mg once daily for 2 to 7 days) followed by oral trovafloxacin (200 mg once daily) for a total of 7 to 14 days of therapy to intravenous ciprofloxacin (400 mg BID) plus ampicillin (500 mg QID) for 2 to 7 days followed by oral ciprofloxacin (500 mg BID) plus amoxicillin (500 mg TID) for a total of 7 to 14 days of therapy. The second study compared intravenous alatrofloxacin (200 mg once daily for 2 to 7 days) followed by oral trovafloxacin (200 mg once daily) for a total of 7 to 14 days of therapy to intravenous ceftriaxone (1000 mg once daily for 2 to 7 days) followed by oral cefpodoxime (400 mg BID) for 7 to 14 days of total therapy with optional blinded erythromycin added to the ceftriaxone/cefpodoxime arm if an atypical pneumonia was suspected.

The clinical success rate (cure + improvement with no need for further antibiotic therapy) at the End of Treatment was 90% (311/346) and 90% (325/363) for trovafloxacin mesylate and the comparator agents, respectively. The clinical success rate at the End of Study (Day 30) was 86% (256/299) and 85% (283/334) for trovafloxacin mesylate and the comparator agents, respectively. All cause mortality (Day 1–35) was 2.45% (10/408) on trovafloxacin mesylate and 5.45% (23/422) on the comparator agents.

The following outcomes are the clinical success rates for the clinically evaluable patient groups by pathogen in these two studies:

Of the above patients with clinical failure at end of treatment or study, only one alatrofloxacin patient (H. influenzae + S. pneumoniae) and one ceftriaxone + erythromycin patient (Legionella) had a microbiologically confirmed persistent pathogen at the time of failure with no emergence of resistance in either study.

Nosocomial Pneumonia

Adult patients with clinically and radiologically documented nosocomial pneumonia participated in a randomized, multicenter, double-blind, double-dummy trial comparing intravenous alatrofloxacin (300 mg once daily for 2 to 7 days) followed by oral trovafloxacin (200 mg once daily) for a total of 7 to 14 days of therapy to intravenous ciprofloxacin (400 mg BID) for 2 to 7 days followed by oral ciprofloxacin (750 mg BID) for a total of 7 to 14 days of therapy with optional blinded clindamycin or metronidazole added to the ciprofloxacin arm if an anaerobic pneumonia was suspected. In subjects with documented Pseudomonas infection or methicillin-resistant S. aureus, aztreonam or vancomycin, respectively, could have been added to either treatment regimen.

The clinical success rate (cure + improvement with no need for further antibiotic therapy) at the End of Treatment was 77% (68/88) and 78% (79/101) for trovafloxacin mesylate and ciprofloxacin, respectively. The clinical success rate at the End of Study (Day 30) was 69% (50/72) and 68% (54/79) for trovafloxacin mesylate and ciprofloxacin, respectively.

The following outcomes are the clinical success rates for the clinically evaluable patient groups by pathogen:

Of the above patients with clinical failure at end of treatment or study, 2 alatrofloxacin patients (S. aureus, P. aeruginosa) and 4 ciprofloxacin patients (all P. aeruginosa) had a microbiologically confirmed persistent pathogen at the time of failure. Three of the 4 ciprofloxacin patients with clinical failure and persistence had emergence of resistance with none on alatrofloxacin.

Complicated Intra-Abdominal Infections

Patients hospitalized with clinically documented, complicated intra-abdominal infections, including post-surgical infections, participated in a randomized, double-blind, multicenter trial comparing intravenous alatrofloxacin (300 mg once daily) followed by oral trovafloxacin (200 mg once daily) to intravenous imipenem/cilastatin (1g q8h) followed by oral amoxicillin/clavulanic acid (500 mg TID) for a maximum of 14 days of therapy. The clinical success rate (cure + improvement) at the End of Treatment was 88% (136/155) and 86% (122/142) for alatrofloxacin→trovafloxacin and imipenem/cilastatin→amoxicillin/clavulanic acid, respectively. The clinical success rate at the End of Study (Day 30) was 83% (129/156) and 84% (127/152) for alatrofloxacin→trovafloxacin and imipenem/cilastatin→amoxicillin/clavulanic acid, respectively.

The following are the clinical success rates for the clinically evaluable patient groups by pathogen:

Of patients with a baseline pathogen and a clinical response of failure at the End of Study, 9 of 26 on trovafloxacin mesylate and 10 of 21 on imipenem/cilastatin had microbiologically-confirmed persistence of the baseline pathogen with no emergence of resistance in either group.

Patient Counseling Information

Patients should be advised:

  • to discontinue therapy and to inform their physician immediately if they develop symptoms suggestive of hepatic dysfunction including fatigue, anorexia, vomiting, abdominal pain, jaundice, dark urine or pale stool.
  • to inform their physician if they develop symptoms suggestive of pancreatitis including abdominal pain and/or nausea and vomiting.
  • that trovafloxacin mesylate Tablets may be taken without regard to meals;
  • that vitamins or minerals containing iron, aluminum- or magnesium-base antacids, antacids containing citric acid buffered with sodium citrate, or sucralfate or Videx®, (Didanosine), chewable/buffered tablets or the pediatric powder for oral solution, should be taken at least 2 hours before or 2 hours after taking trovafloxacin mesylate tablets;
  • that trovafloxacin mesylate may cause lightheadedness and/or dizziness. Dizziness and/or lightheadedness was the most common adverse reaction reported, and for females under 45 years, it was reported significantly more frequently than in other groups. The incidence of dizziness may be substantially reduced if trovafloxacin mesylate Tablets are taken at bedtime or with food. Patients should know how they react to trovafloxacin before they operate an automobile or machinery or engage in activities requiring mental alertness and coordination.;
  • to discontinue treatment and inform their physician if they experience pain, inflammation or rupture of a tendon, and to rest and refrain from exercise until the diagnosis of tendinitis or tendon rupture has been confidently excluded;
  • that trovafloxacin mesylate may be associated with hypersensitivity reactions, even following the first dose, and to discontinue the drug at the first sign of a skin rash, hives or other skin reactions, difficulty in swallowing or breathing, any swelling suggesting angioedema (e.g., swelling of the lips, tongue, face, tightness of the throat, hoarseness), or other symptoms of an allergic reaction;
  • to avoid excessive sunlight or artificial ultraviolet light (e.g., tanning beds) while taking trovafloxacin mesylate and to discontinue therapy if phototoxicity (e.g., sunburn-like reaction or skin eruption) occurs.
  • that convulsions have been reported in patients taking quinolones, including trovafloxacin, and to notify their physician before taking this drug if there is a history of this condition.
