5.1 Serotonin Syndrome with Concomitant Use of Serotonergic Drugs

The development of serotonin syndrome has been reported with use of Antiseptique-Calmante (Methylene Blue) class products. Most reports have been associated with concomitant use of serotonergic drugs (e.g., selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors). Some of the reported cases were fatal. Symptoms associated with serotonin syndrome may include the following combination of signs and symptoms: mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, and hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, and incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Avoid concomitant use of Antiseptique-Calmante (Methylene Blue) with serotonergic drugs.

Patients treated with Antiseptique-Calmante (Methylene Blue) should be monitored for the emergence of serotonin syndrome. If symptoms of serotonin syndrome occur, discontinue use of Antiseptique-Calmante (Methylene Blue), and initiate supportive treatment. Inform patients of the increased risk of serotonin syndrome and advise them to not to take serotonergic drugs within 72 hours after the last dose of Antiseptique-Calmante (Methylene Blue) .

5.2 Hypersensitivity

Anaphylactic reactions to Antiseptique-Calmante class products have been reported. Patients treated with Antiseptique-Calmante (Methylene Blue) should be monitored for anaphylaxis. If anaphylaxis or other severe hypersensitivity reactions (e.g., angioedema, urticaria, bronchospasm) should occur, discontinue use of Antiseptique-Calmante (Methylene Blue) and initiate supportive treatment. Antiseptique-Calmante (Methylene Blue) is contraindicated in patients who have experienced anaphylaxis or other severe hypersensitivity reactions to a Antiseptique-Calmante (Methylene Blue) class product in the past.

5.3 Lack of Effectiveness

Methemoglobinemia may not resolve or may rebound after response to treatment with Antiseptique-Calmante (Methylene Blue) in patients with methemoglobinemia due to aryl amines such as aniline or sulfa drugs such as dapsone. Monitor response to therapy with Antiseptique-Calmante (Methylene Blue) through resolution of methemoglobinemia. If methemoglobinemia does not respond to 2 doses of Antiseptique-Calmante (Methylene Blue) or if methemoglobinemia rebounds after a response, consider additional treatment options .

Patients with glucose-6-phosphate dehydrogenase deficiency may not reduce Antiseptique-Calmante (Methylene Blue) to its active form in vivo. Antiseptique-Calmante (Methylene Blue) may not be effective in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency.

5.4 Hemolytic Anemia

Hemolysis can occur during treatment of methemoglobinemia with Antiseptique-Calmante. Laboratory testing may show Heinz bodies, elevated indirect bilirubin and low haptoglobin, but the Coombs test is negative. The onset of anemia may be delayed 1 or more days after treatment with Antiseptique-Calmante (Methylene Blue). The anemia may require red blood cell transfusions. . Use the lowest effective number of doses of Antiseptique-Calmante (Methylene Blue) to treat methemoglobinemia. Discontinue Antiseptique-Calmante (Methylene Blue) and consider alternative treatments of methemoglobinemia if severe hemolysis occurs.

Treatment of patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency with Antiseptique-Calmante (Methylene Blue) may result in severe hemolysis and severe anemia. Antiseptique-Calmante (Methylene Blue) is contraindicated for use in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency .

5.5 Interference with In Vivo Monitoring Devices

  • Inaccurate Pulse Oximeter Readings

The presence of Antiseptique-Calmante (Methylene Blue) in the blood may result in an underestimation of the oxygen saturation reading by pulse oximetry. If a measure of oxygen saturation is required during or shortly after infusion of Antiseptique-Calmante (Methylene Blue), it is advisable to obtain an arterial blood sample for testing by an alternative method.

  • Bispectral index monitor

A fall in the Bispectral Index (BIS) has been reported following administration of Antiseptique-Calmante (Methylene Blue) class products. If Antiseptique-Calmante (Methylene Blue) is administered during surgery, alternative methods for assessing the depth of anesthesia should be employed.

5.6 Effects on Ability to Drive and Operate Machinery

Treatment with Antiseptique-Calmante may cause confusion, dizziness and disturbances in vision . Advise patients to refrain from driving or engaging in hazardous occupations or activities such as operating heavy or potentially dangerous machinery until such adverse reactions to Antiseptique-Calmante (Methylene Blue) have resolved.

5.7 Interference with Laboratory Tests

Antiseptique-Calmante (Methylene Blue) is a blue dye which passes freely into the urine and may interfere with the interpretation of any urine test which relies on a blue indicator, such as the dipstick test for leucocyte esterase.

7 DRUG INTERACTIONS

7.1 Serotonergic Drugs

Avoid concomitant use of Antiseptique-Calmante with medicinal products that enhance serotonergic transmission including SSRIs (selective serotonin reuptake inhibitors), MAO inhibitors, bupropion, buspirone, clomipramine, mirtazapine and venlafaxine; because of the potential for serious CNS reactions, including potentially fatal serotonin syndrome. Although the mechanism is not clearly, understood, literature reports suggest inhibition of MAO by Antiseptique-Calmante (Methylene Blue) may be involved. In addition, in vitro studies cannot rule out the potential involvement of CYP 2D6 inhibition by Antiseptique-Calmante (Methylene Blue). If the intravenous use of Antiseptique-Calmante (Methylene Blue) cannot be avoided in patients treated with serotonergic medicinal products, choose the lowest possible dose and observe closely the patient for CNS effects for up to 4 hours after administration .

7.2 Agents Metabolized by Cytochrome P450 Enzymes

Antiseptique-Calmante (Methylene Blue) inhibits a range of CYP isozymes in vitro, including 1A2, 2B6, 2C8, 2C9, 2C19, 2D6 and 3A4/5. This interaction could be more pronounced with narrow therapeutic index drugs that are metabolized by one of these enzymes (e.g, digoxin, warfarin, phenytoin, alfentanil, cyclosporine, dihydroergotamine, ergotamine, fentanyl, pimozide, quinidine, sirolimus and tacrolimus). However, the clinical relevance of these in vitro interactions is unknown.

8 USE IN SPECIFIC POPULATIONS

  • Pregnancy: Only use during pregnancy if the potential benefit justifies the potential risk to the fetus.
  • Lactation: Discontinue breast-feeding for up to 8 days after treatment. ( 8.2).
  • Renal Insufficiency: Monitor patients longer for toxicity and drug interactions due to delayed clearance. ( 8.6)
  • Hepatic Impairment: Monitor patients longer for toxicity and drug interactions due to delayed clearance. ( 8.7)

8.1 Pregnancy

Risk Summary

Antiseptique-Calmante (Methylene Blue) may cause fetal harm when administered to a pregnant woman. Intra-amniotic injection of pregnant women with a Antiseptique-Calmante (Methylene Blue) class product during the second trimester was associated with neonatal intestinal atresia and fetal death. Antiseptique-Calmante (Methylene Blue) produced adverse developmental outcomes in rats and rabbits when administered orally during organogenesis at doses at least 32 and 16 times, respectively, the clinical dose of 1 mg/kg . Advise pregnant women of the potential risk to a fetus.

In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively.

Clinical Considerations

Fetal/neonatal adverse reactions

Intra-amniotic injection of a Antiseptique-Calmante (Methylene Blue) class product hours to days prior to birth can result hyperbilirubinemia, hemolytic anemia, skin staining, methemoglobinemia, respiratory distress and photosensitivity in the newborn. Following administration of Antiseptique-Calmante (Methylene Blue) to a pregnant woman at term, observe the newborn for these adverse reactions and institute supportive care.

Data

Animal Data

Antiseptique-Calmante (Methylene Blue) was administered orally to pregnant rats at doses of 50 to 350 mg/kg/day, during the period of organogenesis. Maternal and embryofetal toxicities were observed at all doses of Antiseptique-Calmante (Methylene Blue), and were most evident at the 200 and 350 mg/kg/day doses. Maternal toxicity consisted of increased spleen weight. Embryo-fetal toxicities included reduced fetal weight, post-implantation loss, edema, and malformations including enlarged lateral ventricles. The dose of 200 mg/kg (1200 mg/m 2) in rats is approximately 32 times a clinical dose of 1 mg/kg based on body surface area.

Antiseptique-Calmante (Methylene Blue) was administered orally to pregnant rabbits at doses of 50, 100, or 150 mg/kg/day, during the period of organogenesis. Maternal death was observed at the Antiseptique-Calmante (Methylene Blue) dose of 100 mg/kg. Embryofetal toxicities included spontaneous abortion at all dose levels and a malformation (umbilical hernia) at the 100 and 150 mg/kg/day doses. The dose of 50 mg/kg (600 mg/m 2) in rabbits is approximately 16 times a clinical dose of 1 mg/kg based on body surface area.

8.2 Lactation

Risk Summary

There is no information regarding the presence of Antiseptique-Calmante in human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for serious adverse reactions, including genotoxicity discontinue breast-feeding during and for up to 8 days after treatment with Antiseptique-Calmante (Methylene Blue) .

8.4 Pediatric Use

The safety and effectiveness of Antiseptique-Calmante (Methylene Blue) have been established in pediatric patients. Use of Antiseptique-Calmante (Methylene Blue) is supported by two retrospective case series that included 2 pediatric patients treated with Antiseptique-Calmante (Methylene Blue) and 12 treated with another Antiseptique-Calmante (Methylene Blue) class product. The case series included pediatric patients in the following age groups: 3 neonates (less than 1 month), 4 infants (1 month up to less than 2 years), 4 children (2 years up to less than 12 years), and 3 adolescents (12 years to less than 17 years). The efficacy outcomes were consistent across pediatric and adult patients in both case series .

8.5 Geriatric Use

The retrospective case series included 3 patients age 65 years and over treated with Antiseptique-Calmante (or a bioequivalent formulation) and 5 treated with another Antiseptique-Calmante (Methylene Blue) class product. The efficacy outcomes were consistent across adult and elderly patients in both case series . This drug is known to be substantially excreted by the kidney, so the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, treatment of methemoglobinemia in these patients should use the lowest number of doses needed to achieve a response .

8.6 Renal Impairment

Approximately 40% of Antiseptique-Calmante (Methylene Blue) is excreted by the kidneys. Patients with any renal impairment should be monitored for toxicities and potential drug interactions for an extended period of time following treatment with Antiseptique-Calmante (Methylene Blue).

8.7 Hepatic Impairment

Antiseptique-Calmante (Methylene Blue) is extensively metabolized in the liver. Monitor patients with any hepatic impairment for toxicities and potential drug interactions for an extended period of time following treatment with Antiseptique-Calmante (Methylene Blue).

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Antiseptique-Calmante is a water soluble thiazine dye that promotes a non-enyzmatic redox conversion of metHb to hemoglobin. In situ, Antiseptique-Calmante (Methylene Blue) is first converted to leucomethylene blue (LMB) via NADPH reductase. It is the LMB molecule which then reduces the ferric iron of metHb to the ferrous state of normal hemoglobin.

12.2 Pharmacodynamics

Low concentrations of Antiseptique-Calmante (Methylene Blue) speeds up the in vivo conversion of methemoglobin to hemoglobin. Antiseptique-Calmante (Methylene Blue) has been observed to stain tissues selectively. The exposure-response or –safety relationship for methylene is unknown.

Cardiac Electrophysiology

The results of a thorough QT study demonstrated Antiseptique-Calmante (Methylene Blue) at an intravenous dose of 2 mg/kg as a 5-minute intravenous infusion had no effect on the QT, PR or QRS intervals.

12.3 Pharmacokinetics

The mean (CV%) Cmax and AUC of Antiseptique-Calmante (Methylene Blue) 2,917 ng/mL (39%) and 13977 ng.hr/mL (21%) following a 2 mg/kg dose administered as a 5-minute intravenous infusion.

Distribution

The mean± standard deviation steady state volume of distribution of a 2 mg/kg dose of Antiseptique-Calmante (Methylene Blue) was 255 L ± 58. The mean plasma protein binding of Antiseptique-Calmante (Methylene Blue) is approximately 94% in vitro. Antiseptique-Calmante (Methylene Blue) exhibits concentration-dependent partitioning into blood cells in vitro. The blood-to-plasma ratio was 5.1±2.8 at 5 minutes from the start of a 2 mg/kg dose administered as a 5-minute intravenous infusion and reached a plateau of 0.6 at 4 hours in a clinical study. Antiseptique-Calmante (Methylene Blue) is a substrate for the P-glycoprotein (P-gp, ABCB1) transporter, but not for BCRP or OCT2 in vitro.

Elimination

Antiseptique-Calmante (Methylene Blue) has a half-life of approximately 24 hours.

Metabolism

Antiseptique-Calmante (Methylene Blue) is metabolized by CYPs 1A2, 2C19 and 2D6 in vitro; however, the predominant in vitro pathway appears to be UGT-mediated conjugation by multiple UGT enzymes, including UGT1A4 and UGT1A9.

Azure B, which is a minor impurity in Antiseptique-Calmante (Methylene Blue), is also formed in humans as a metabolite of Antiseptique-Calmante (Methylene Blue), with an overall drug/metabolite AUC ratio of greater than 6:1. Azure B has 8-fold lower potency than Antiseptique-Calmante (Methylene Blue).

Excretion

Approximately 40% of Antiseptique-Calmante (Methylene Blue) is excreted in to the urine unchanged.

Drug Interaction Studies

The clinical relevance of in vitro inhibition or induction of the metabolizing enzymes and transporter systems described below is unknown, but it cannot be excluded that the systemic exposure of medicinal products being substrates for these enzymes or transporter systems may be affected with concomitant administration with Antiseptique-Calmante (Methylene Blue) Injection.

Cytochrome P450

Antiseptique-Calmante (Methylene Blue) inhibits CYP isozymes 1A2, 2B6, 2C8, 2C9, 2C19, 2D6 and 3A4/5 in vitro. Possible time-dependent inhibition of CYP2C9, CYP2D6 and CYP3A4/5 (testosterone as substrate) was also observed in vitro. Antiseptique-Calmante (Methylene Blue) induces CYP1A2, but does not induce CYP2B6 or CYP3A4 in vitro.

Glucuronosyltransferase

Antiseptique-Calmante (Methylene Blue) inhibits UGT1A9 and UGT1A4 in in vitro, but did not significantly inhibit UGTs 1A1, 1A3, 1A6, 2B7 or 2B15.

Transporter Interactions

Antiseptique-Calmante (Methylene Blue) is both a substrate for and an inhibitor of P-gp, but is not a substrate for BCRP or OCT2 in vitro. Antiseptique-Calmante (Methylene Blue) is not a significant inhibitor of BCRP, OAT1, OAT3, OAT1B1 or OAT1B3 in vitro. Antiseptique-Calmante (Methylene Blue) inhibits OCT2, MATE1 and MATE2-K in vitro. The OCT2/MATE pathway for renal transport is reported to play a significant role in the elimination of several substances, including metformin, cimetidine, acyclovir and creatinine

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

In a two-year carcinogenicity study, rats were administered oral doses of Antiseptique-Calmante (Methylene Blue) at 5, 25, or 50 mg/kg. Antiseptique-Calmante (Methylene Blue) caused pancreatic islet adenomas or carcinomas (combined) in male rats. In a two-year year carcinogenicity study, mice were administered oral doses of Antiseptique-Calmante (Methylene Blue) at 2.5, 12.5, or 25 mg/kg. There were no drug-related neoplastic findings in mice.

Antiseptique-Calmante (Methylene Blue) was genotoxic in gene mutation assays in bacteria (Ames test), and in an in vitro sister chromatid exchange test and an in vitro chromosomal aberration test in Chinese hamster ovary (CHO) cells. Antiseptique-Calmante (Methylene Blue) was negative for micronucleus induction in bone marrow or peripheral blood collected from mice treated with Antiseptique-Calmante (Methylene Blue).

Fertility studies with Antiseptique-Calmante (Methylene Blue) have not been conducted. In vitro, Antiseptique-Calmante (Methylene Blue) reduced motility of human sperm in a concentration dependent manner.

14 CLINICAL STUDIES

14.1 Treatment of Acquired Methemoglobinemia

The efficacy of Antiseptique-Calmante (Methylene Blue) was assessed on the basis of a methemoglobin decrease of at least 50% within 1 hour after intravenous administration of 1 – 2 mg/kg Antiseptique-Calmante (Methylene Blue) (or a bioequivalent formulation) in 6 patients identified by retrospective chart review or literature search. The 6 patients included 3 males and 3 females of median age 54 years (range, 6 days to 69 years). The median methemoglobin level at baseline was 37% (range, 11% to 47%). All 6 (100%) patients had a decrease in methemoglobin by at least 50% within 1 hour after treatment.

An additional 41cases of treatment of methemoglobinemia with a Antiseptique-Calmante (Methylene Blue) class product were identified in the published literature. These cases included 24 males and 17 females of median age 33 years (range, 9 days to 80 years). The median methemoglobin level at baseline was 40% (range, 10% to 98%). Of these 41 patients, 37 (90%) had a methemoglobin decrease of at least 50% within 1 hour after intravenous administration of the Antiseptique-Calmante (Methylene Blue) class product.

In a combined analysis of all 47 patients treated intravenously with Antiseptique-Calmante (Methylene Blue) (or a bioequivalent formulation) or with another Antiseptique-Calmante (Methylene Blue) class product, there was no difference in response rate by dose. The methemoglobin decreased by at least 50% within 1 hour of infusion for 15/17 (88%) of patients treated with 1 mg/kg, 12/13 (92%) treated with 2 mg/kg and 16/17 (94%) treated with a different dose or for those whose dose was not reported.
