Otezla (apremilast)

Otezla (apremilast) is not a biologic agent, but we are including it in the chart because it is FDA approved treat psoriasis in situations where a biologic may be considered, and for reader convenience

Starter Pak: Take as directed (Given in office).
Maintenance: Take 30mg twice daily. (12 hours apart)
Tablets No lab work needed Psoriasis and Psoriatic Arthritis Hypersensitivity to Apremilast or to any excipients in the formulation The effect of apremilast on vaccine-mediated immune responses has not been clinically assessed. Apremilast is an oral small-molecule inhibitor of phosphodiesterase 4 (PDE4) specific for cyclic adenosine monophosphate (cAMP) PDE4 inhibition results in increased intracellular cAMP levels. None
Dupixent (dupilumab) inject 300mg Initial Dose: Inject 600mg (2 pens) Subcutaneously on Day 1. Maintenance Dose: Inject 300mg (1pen) Subcutaneously every 2 weeks starting Day 15 and thereafter. Prefilled Syringe None Dupixent is an interleukin-4 receptor alpha antagonist for the treatment of ADULT over the age of 18 patients with moderate-to-severe ATOPIC DERMATITS whose disease id not adequately controlled with topical prescription therapies or when therapies are not advisable. Dupixent can be used with or without corticosteroids. Dupixent is contraindicated in patients who have known hypersensitivity to dupixent or any if it excipient (see 5.1 on the Medication guided for further information) NO LIVE Vaccines while on DUPIXENT

Dupilumab is a human monoclonal IgG4 antibody that inhibits interleukin-4 (IL-4) and interleukin-13 (IL-13) signaling by specifically binding to the IL-4Ra subunit shared by the IL-4 and IL-13 receptor complexes. Dupilumab inhibits IL-4 signaling via the Type I receptor and both IL-4 and IL-13 signaling through the Type II receptor.

Blocking IL-4a with dupilumab inhibits IL-4 and IL-13 cytokinr-induced responses, including the release of proinflammatory, cytokines, chemokines and IgE.

None
Remicade (INFLIXMAB) Initial Dose: 5 mg/kg given as an intravenous induction regimen at 0, 2 and 6 weeks. Maintenance: regimen of 5 mg/kg every 8 weeks thereafter for the treatment of chronic severe (i.e., extensive and/or disabling) plaque psoriasis. IV infusion TB (Mantoux) prior starting and yearly Plaque Psoriasis and Psoriatic Arthritis REMICADE at doses >5 mg/kg should not be administered to patients with moderate to severe heart failure. In a randomized study evaluating REMICADE in patients with moderate to severe heart failure (New York Heart Association REMICADE ® (infliximab) REMICADE ® (infliximab) 4 [NYHA] Functional Class III/IV), REMICADE treatment at 10 mg/kg was associated with an increased incidence of death and hospitalization due to worsening heart failure [see Warnings and Precautions (5.5) and Adverse Reactions (6.1)]. REMICADE should not be re-administered to patients who have experienced a severe hypersensitivity reaction to REMICADE. Additionally, REMICADE should not be administered to patients with known hypersensitivity to inactive components of the product or to any murine proteins. No live vaccines Infliximab neutralizes the biological activity of TNF-alpha by binding with high affinity to the soluble and transmembrane forms of TNF-alpha and inhibits binding of TNF-alpha with its receptors. Infliximab does not neutralize TNF-beta (lymphotoxin-alpha), a related cytokine that utilizes the same receptors as TNF-alpha. Biological activities attributed to TNF-alpha 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 TNF-alpha bound by infliximab can be lysed in vitro or in vivo. Infliximab inhibits the functional activity of TNF-alpha 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 REMICADE exerts its clinical effects is unknown. Anti-TNF-alpha 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 TNF-alpha, and when administered after disease onset, allows eroded joints to heal.

Xolair (Omalizumab)

Asthma: Xolair 75 to 375mg SC every 2 or 4 weeks. -Determine dose (mg) and dosing frequency by serum total IgE level (IU/mL), measured before the start of treatment, and body weight (kg)

Urticaria: Xolair 150 or 300mg SC every 4 weeks. Dosing in CIU is not dependent on serum IgE level or body weight.

Vial In asthma patients, a blood test for a substance called IgE must be performed prior to starting XOLAIR to determine the appropriate dose and dosing frequency. No labs needed for patient with chronic idiopathic Urticaria Moderate to severe persistent asthma in patients 6 years of age and older or Chronic Idiopathic Urticaria. Patients who are allergic to omalizumab or any of the ingredients.

Have any other allergies (such as food allergy or seasonal allergies)

Have sudden breathing problems (bronchospasm)

Have ever had a severe allergic reaction called anaphylaxis

Have or have had a parasitic infection

Cancer are pregnant or plan to become pregnant.

Breastfeeding or plan to breastfeed.

Asthma Omalizumab inhibits the binding of IgE to the high-affinity IgE receptor (Fc small letter epsilon RI) on the surface of mast cells and basophils. Reduction in surface-bound IgE on Fc small letter epsilon RI -bearing cells limits the degree of release of mediators of the allergic response. Treatment with Xolair also reduces the number of Fc small letter epsilon RI receptors on basophils in atopic patients. Chronic Idiopathic Urticaria Omalizumab binds to IgE and lowers free IgE levels. Subsequently, IgE receptors (Fc small letter epsilon RI) on cells down -regulate. The mechanism by which these effects of omalizumab NAPHYLAXIS See full prescribing information for complete boxed warning.Anaphylaxis, presenting as bronchospasm, hypotension, syncope, urticaria, and/or angioedema of the throat or tongue, has been reported to occur after administration of Xolair. Anaphylaxis has occurred after the first dose of Xolair but also has occurred beyond 1year after beginning treatment. Closely observe patients for an appropriate period of time after Xolair administration and be prepared to manage anaphylaxis that can be life-threatening. Inform patients of the signs and symptoms of anaphylaxis and have them seek immediate medical care should symptoms occur. (5.1)

Before starting check TB status, HIV status, Hepatitis panel and fungal serologies, if indicated, (e.g. participates outdoor activities with high rate of blasto/other exposure).

Many people on Cosentyx experience weight loss, be sure to monitor for weight change at visits.

IL-17 antagonists have been reported to cause a flare in patients with inflammatory bowel disease, be sure to consider this when starting a ptient on an IL-17 antagonist (Talz and Cosentyx)
