INFLIXIMAB

INFLIXIMAB

Standard Dose
2 DOSAGE AND ADMINISTRATION Prior to treatment, ensure appropriate personnel and medication are available to treat reactions (e.g., hypersensitivity) that occur during infusion and shortly after infusion. ( 2.11 ) Infliximab is administered by intravenous infusion for at least 2 hours with an in-line filter ( 2.11 ) Crohn's Disease : 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks. Some adult patients who initially respond to treatment may benefit from increasing the dose to 10 mg/kg every 8 weeks if they later lose their response. ( 2.1 ) Pediatric Crohn's Disease (≥ 6 years old) : 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks. ( 2.2 ) Ulcerative Colitis : 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks. ( 2.3 ) Pediatric Ulcerative Colitis (≥ 6 years old) : 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks. ( 2.4 ) Rheumatoid Arthritis : In conjunction with methotrexate, 3 mg/kg at 0, 2 and 6 weeks, then every 8 weeks. Some patients may benefit from increasing the dose up to 10 mg/kg every 8 weeks or treating as often as every 4 weeks. ( 2.5 ) Ankylosing Spondylitis : 5 mg/kg at 0, 2 and 6 weeks, then every 6 weeks. ( 2.6 ) Psoriatic Arthritis and Plaque Psoriasis : 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks. ( 2.7 , 2.8 ) 2.1 Dosage in Adult Crohn's Disease The recommended dosage of Infliximab is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 8 weeks thereafter for the treatment of adults with moderately to severely active CD or fistulizing CD. For adult patients who respond and then lose their response, consideration may be given to treatment with 10 mg/kg every 8 weeks. Patients who do not respond by Week 14 are unlikely to respond with continued dosing and consideration should be given to discontinue Infliximab in these patients. 2.2 Dosage in Pediatric Crohn's Disease The recommended dosage of Infliximab for pediatric patients 6 years and older with moderately to severely active CD is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 8 weeks. 2.3 Dosage in Adult Ulcerative Colitis The recommended dosage of Infliximab is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 8 weeks thereafter for the treatment of adult patients with moderately to severely active UC. 2.4 Dosage in Pediatric Ulcerative Colitis The recommended dosage of Infliximab for pediatric patients 6 years and older with moderately to severely active UC is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 8 weeks. 2.5 Dosage in Rheumatoid Arthritis The recommended dosage of Infliximab is 3 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 3 mg/kg every 8 weeks thereafter for the treatment of moderately to severely active RA. Infliximab should be given in combination with methotrexate. For patients who have an incomplete response, consideration may be given to adjusting the dosage up to 10 mg/kg every 8 weeks or treating as often as every 4 weeks bearing in mind that risk of serious infections is increased at higher doses per infusion or more frequent dosing [see Adverse Reactions (6.1) ] . 2.6 Dosage in Ankylosing Spondylitis The recommended dosage of Infliximab is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 6 weeks thereafter for the treatment of active AS. 2.7 Dosage in Psoriatic Arthritis The recommended dosage of Infliximab is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 8 weeks thereafter for the treatment of PsA. Infliximab can be used with or without methotrexate. 2.8 Dosage in Plaque Psoriasis The recommended dosage of Infliximab in adult patients is 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks followed by a maintenance regimen of 5 mg/kg every 8 weeks thereafter for the treatment of chronic severe (i.e., extensive and/or disabling) Ps. 2.9 Assessment for Latent and Active Tuberculosis Prior to initiating Infliximab and periodically during therapy, patients should be evaluated for active tuberculosis and tested for latent infection [see Warnings and Precautions (5.1) ] . 2.10 Administration Instructions Regarding Infusion Reactions Prior to treatment, ensure appropriate personnel and medication are available to treat reactions (e.g., hypersensitivity, other reactions) that occur during infusion and shortly after infusion. Prior to infusion with Infliximab, patients may be premedicated with histamine-1 receptor antagonists, histamine-2 receptor antagonists, acetaminophen, and/or corticosteroids [see Warnings and Precautions (5.7) ] . For mild to moderate reactions during the infusion, consider slowing or stopping the infusion. Upon resolution of these reactions, may reinitiate at a lower infusion rate and/or with histamine-1 receptor antagonists, histamine-2 receptor antagonists, acetaminophen, and/or corticosteroids. Discontinue the infusion if the mild to moderate reactions reoccur. Discontinue the infusion if severe hypersensitivity reactions occur during the infusion. 2.11 Reconstitution, Dilution, and Administration Instructions Infliximab is intended for use under the guidance and supervision of a healthcare provider. The supplied lyophilized powder must be reconstituted and diluted prior to administration. The infusion solution should be prepared and administered by a trained medical professional using aseptic technique by the following procedure: Calculate the dose, total volume of reconstituted Infliximab solution required and the number of Infliximab vials needed. More than one vial may be needed for a full dose. Reconstitute each 100 mg Infliximab vial with 10 mL of Sterile Water for Injection, USP, to obtain a concentration of 10 mg/mL, using a syringe equipped with a 21-gauge or smaller needle as follows: Remove the flip-top from the vial and wipe the top with an alcohol swab. Insert the syringe needle into the vial through the center of the rubber stopper and direct the stream of Sterile Water for Injection, USP, to the glass wall of the vial. Gently swirl the solution by rotating the vial to dissolve the lyophilized powder, which has a cake-like appearance. Avoid prolonged or vigorous agitation. DO NOT SHAKE. Foaming of the solution on reconstitution is not unusual. Allow the reconstituted solution to stand for 5 minutes. Visually inspect the reconstituted solution for particulate matter and discoloration. The reconstituted solution should be colorless to light yellow and opalescent, and the solution may develop a few translucent particles as infliximab is a protein. Do not use if the lyophilized powder has not fully dissolved or if opaque particles, discoloration, or other foreign particles are present. Do not store unused reconstituted Infliximab solution. Dilute the total volume of the reconstituted Infliximab solution to 250 mL For volumes greater than 250 mL, either use a larger infusion bag (e.g. 500 mL) or multiple 250 mL infusion bags to ensure that the concentration of the infusion solution does not exceed 4 mg/mL. with sterile 0.9% Sodium Chloride Injection, USP, (do not dilute with any other diluent) as follows: Withdraw a volume from the 0.9% Sodium Chloride Injection, USP, 250 mL bottle or bag equal to the total volume of reconstituted Infliximab required for a dose. Slowly add the total volume of reconstituted Infliximab solution from the vial(s) to the 250 mL infusion bottle or bag. Discard any unused portion of the reconstituted Infliximab solution remaining in the vial(s). Gently invert the bag to mix the solution. The resulting infusion concentration should range between 0.4 mg/mL (minimum recommended concentration) and 4 mg/mL (maximum recommended concentration) of infliximab. The Infliximab infusion should begin within 3 hours of reconstitution and dilution. The infusion must be administered intravenously for at least 2 hours with an infusion set with an in-line, sterile, non-pyrogenic, low-protein-binding filter (pore size of 1.2 µm or less). Given that the vials do not contain antibacterial preservatives, discard any unused portion of the infusion solution (do not store for reuse). No physical biochemical compatibility studies have been conducted to evaluate the co-administration of Infliximab with other agents. Infliximab should not be infused concomitantly in the same intravenous line with other agents.

Boxed Warning

WARNING: SERIOUS INFECTIONS and MALIGNANCY WARNING: SERIOUS INFECTIONS and MALIGNANCY See full prescribing information for complete boxed warning. Increased risk of serious infections leading to hospitalization or death, including tuberculosis (TB), bacterial sepsis, invasive fungal infections (such as histoplasmosis) and infections due to other opportunistic pathogens. ( 5.1 ) Discontinue Infliximab if a patient develops a serious infection. Perform test for latent TB; if positive, start treatment for TB prior to starting Infliximab. Monitor all patients for active TB during treatment, even if initial latent TB test is negative. ( 5.1 ) Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with tumor necrosis factor (TNF) blockers, including Infliximab. ( 5.2 ) Postmarketing cases of fatal hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF blockers including Infliximab. Almost all had received azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. The majority of Infliximab cases were reported in patients with Crohn's disease or ulcerative colitis, most of whom were adolescent or young adult males. ( 5.2 ) SERIOUS INFECTIONS Patients treated with Infliximab are at increased risk for developing serious infections that may lead to hospitalization or death [see Warnings and Precautions (5.1) and Adverse Reactions (6.1) ] . Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. Infliximab should be discontinued if a patient develops a serious infection or sepsis. Reported infections include: Active tuberculosis, including reactivation of latent tuberculosis. Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent tuberculosis before Infliximab use and during therapy. Treatment for latent infection should be initiated prior to Infliximab use. Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness. Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria. The risks and benefits of treatment with Infliximab should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with Infliximab, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. MALIGNANCY Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, including Infliximab [see Warnings and Precautions (5.2) ] . Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers including Infliximab. These cases have had a very aggressive disease course and have been fatal. Almost all patients had received treatment with azathioprine or 6-mercaptopurine concomitantly with a TNF blocker at or prior to diagnosis. The majority of reported Infliximab cases have occurred in patients with Crohn's disease or ulcerative colitis and most were in adolescent and young adult males.

Monitoring

  • 5 WARNINGS AND PRECAUTIONS Serious infections – do not give Infliximab during an active infection.
  • If an infection develops, monitor carefully and stop Infliximab if infection becomes serious.
  • ( 5.1 ) Invasive fungal infections – for patients who develop a systemic illness on Infliximab, consider empiric antifungal therapy for those who reside or travel to regions where mycoses are endemic ( 5.1 ) Malignancies – the incidence of malignancies, including invasive cervical cancer and lymphoma, was greater in Infliximab treated patients than in controls.
  • Due to the risk of HSTCL carefully assess the risk/benefit especially if the patient has Crohn's disease or ulcerative colitis, is male, and is receiving azathioprine or 6-mercaptopurine treatment.

Interaction Notes

  • 7 DRUG INTERACTIONS Other Biological Products – increased risk of serious infections.
  • ( 7.1 ) 7.1 Other Biological Products The combination of Infliximab with other biological products used to treat the same conditions as Infliximab is not recommended [see Warnings and Precautions (5.10) ] .
  • An increased risk of serious infections was seen in clinical studies of other TNF blockers used in combination with anakinra or abatacept, with no added clinical benefit.
  • Because of the nature of the adverse reactions seen with these combinations with TNF blocker therapy, similar toxicities may also result from the combination of anakinra or abatacept with other TNF blockers.
