Remicade Intravitreal Injection

Infliximab neutralizes the biological activity of TNFα by binding with high affinity to the soluble and transmembrane forms of TNFα and inhibits binding of TNFα with its receptors. Infliximab does not neutralize TNFα (lymphotoxin-α), a related cytokine that utilizes the same receptors as TNFα. Biological activities attributed to TNFα include: induction of pro inflammatory cytokines such as interleukins (IL) 1 and 6, enhancement of leukocyte migration by increasing endothelial layer permeability and expression of adhesion molecules by endothelial cells and leukocytes, activation of neutrophil and eosinophil functional activity, induction of acute phase reactants and other liver proteins, as well as tissue degrading enzymes produced by synoviocytes and/or chondrocytes. Cells expressing transmembrane TNFα bound by infliximab can be lysed in vitro or in vivo. Infliximab inhibits the functional activity of TNFα in a wide variety of in vitro bioassays utilizing human fibroblasts, endothelial cells, neutrophils, B and T lymphocytes and epithelial cells. The relationship of these biological response markers to the mechanism(s) by which Infliximab exerts its clinical effects is unknown. Anti-TNFα antibodies reduce disease activity in the cotton-top tamarin colitis model, and decrease synovitis and joint erosions in a murine model of collagen-induced arthritis. Infliximab prevents disease in transgenic mice that develop polyarthritis as a result of constitutive expression of human TNFα, and when administered after disease onset, allows eroded joints to heal.

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 if they later lose their response.

Pediatric Crohn’s Disease: 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks.

Ulcerative Colitis: 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks.

Pediatric Ulcerative Colitis: 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks.

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 or treating as often as every 4 weeks.

Ankylosing Spondylitis: 5 mg/kg at 0, 2 and 6 weeks, then every 6 weeks.

Psoriatic Arthritis and Plaque Psoriasis: 5 mg/kg at 0, 2 and 6 weeks, then every 8 weeks.

Infliximab is administered by intravenous infusion over a period of not less than 2 hours.

Use with anakinra or abatacept- increased risk of serious infections

Infliximab doses >5 mg/kg in moderate to severe heart failure. Previous severe hypersensitivity reaction to Infliximab or known hypersensitivity to inactive components of Infliximab or to any murine proteins.

Most common adverse reactions (>10%)- infections (e.g. upper respiratory, sinusitis, and pharyngitis), infusion-related reactions, headache, and abdominal pain.

Pregnancy Category B. It is not known whether Infliximab can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity.

It is not known whether Infliximab is excreted in human milk or absorbed systemically after ingestion. Because many drugs and immunoglobulins are excreted in human milk, and because of the potential for adverse reactions in nursing infants from Infliximab, women should not breast-feed their infants while taking Infliximab.

Serious infections- do not give Remicade during an active infection. If an infection develops, monitor carefully and stop Remicade if infection becomes serious.

Invasive fungal infections- for patients who develop a systemic illness on Remicade, consider empiric antifungal therapy for those who reside or travel to regions where mycoses are endemic

Malignancies- the incidence of malignancies including lymphoma was greater in Remicade 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.

Hepatitis B virus reactivation- test for HBV infection before starting Remicade. Monitor HBV carriers during and several months after therapy. If reactivation occurs, stop Remicade and begin anti-viral therapy.

Hepatotoxicity- rare severe hepatic reactions, some fatal or
necessitating liver transplantation. Stop Remicade in cases of jaundice and/or marked liver enzyme elevations.

Heart failure- new onset or worsening symptoms may occur.

Cytopenias- advise patients to seek immediate medical attention if signs and symptoms develop, and consider stopping Remicade.

Hypersensitivity- serious infusion reactions including anaphylaxis or serum sickness-like reactions may occur. 

Demyelinating disease- exacerbation or new onset may occur.

Lupus-like syndrome- stop Remicade if syndrome develops.

Live vaccines or therapeutic infectious agents- should not be given with Remicade. Bring pediatric patients

Pediatric Use: Remicade has not been studied in children with Crohn’s disease or ulcerative colitis<6 years of age.

Targeted Cancer Therapy

Remicade must be refrigerated at 2ºC to 8ºC. Do not use Remicade beyond the expiration date (Exp) located on the carton and the vial. Remicade contains no preservative.
