A commitment to your safety
When your doctor writes you a prescription for TYSABRI, both of you will review, complete, and sign the enrollment form for the TOUCH ® Prescribing Program. This is to make sure that you are informed about the risks of treatment with TYSABRI, including the risk of progressive multifocal leukoencephalopathy (PML).
Getting started
Once you are enrolled in the TOUCH Prescribing Program, you will receive several important phone calls that will help you get started on TYSABRI as smoothly and as quickly as possible. These calls will come from a Support Coordinator from Biogen and from your TOUCH-authorized infusion center and pharmacy.
At the infusion center
TOUCH-authorized centers are staffed by nurses who are committed to your safety while taking TYSABRI. They are committed to the TOUCH program and will educate you on the potential risks of TYSABRI, ensure that you have read and understand the TYSABRI Medication Guide, and answer any questions about your relapsing MS infusion.
How often is Tysabri monitored?
Tysabri patients are typically monitored every three months or so via bloodwork to see if we’ve contracted the JC virus. The risk of PML is yet another individual journey that MSers must take. For some, it scares them away from Tysabri completely.
Is Tysabri a game changer?
For me, Tysabri was a game-changer because it has, for the moment (fingers crossed, knock on wood, etc.), stopped or dramatically slowed my transition into secondary-progressive MS.
Are there any side effects that may occur after long-term treatment with Tysabri?
Yes, long-term treatment with Tysabri can raise your risk of certain side effects, such as serious infection. This includes a serious brain infection called progressive multifocal leukoencephalopathy (PML).
Weight gain
Weight gain is a possible side effect of Tysabri. However, this side effect was rarely reported in clinical trials. Weight loss was also a rare side effect in people who took Tysabri.
Fatigue
Fatigue was a common side effect of Tysabri reported in clinical trials. However, it was typically mild.
Liver damage
While rare, liver damage has been reported in clinical trials of Tysabri. In extreme cases, some people needed a liver transplant due to this side effect.
Serious brain infection
Tysabri has a boxed warning * about a rare but serious brain infection called progressive multifocal leukoencephalopathy (PML). This is a serious warning from the Food and Drug Administration (FDA). Boxed warnings alert healthcare professionals and patients about the most serious side effects a drug may cause.
Allergic reaction
As with most drugs, Tysabri can cause an allergic reaction in some people. For more information on this side effect, see the drug’s prescribing information.
Boxed warning: Serious brain infection
This drug has a boxed warning about a serious brain infection called progressive multifocal leukoencephalopathy (PML). This is a serious warning from the FDA. For details, see the “ Side effect specifics ” section above.
How much Tysabri should I take for MS?
The recommended dose of TYSABRI for multiple sclerosis is 300 mg intravenous infusion over one hour every four weeks.
What is the 4 subunit of Natalizumab?
Natalizumab binds to the 4-subunit of 41 and 47 integrins expressed on the surface of all leukocytes except neutrophils, and inhibits the 4-mediated adhesion of leukocytes to their counter-receptor(s). The receptors for the 4 family of integrins include vascular cell adhesion molecule-1 (VCAM-1), which is expressed on activated vascular endothelium, and mucosal addressin cell adhesion molecule-1 (MAdCAM-1) present on vascular endothelial cells of the gastrointestinal tract. Disruption of these molecular interactions prevents transmigration of leukocytes across the endothelium into inflamed parenchymal tissue. In vitro, anti-4-integrin antibodies also block 4-mediated cell binding to ligands such as osteopontin and an alternatively spliced domain of fibronectin, connecting segment-1 (CS-1). In vivo, natalizumab may further act to inhibit the interaction of 4-expressing leukocytes with their ligand(s) in the extracellular matrix and on parenchymal cells, thereby inhibiting further recruitment and inflammatory activity of activated immune cells.
Does Tysabri increase neutrophils?
TYSABRI does not affect the absolute count of circulating neutrophils [see Warnings and Precautions (5.7)].
Is there any data on the effects of tysabri?
No data are available on the effects of vaccination in patients receiving TYSABRI. No data are available on the secondary transmission of infection by live vaccines in patients receiving
Does Tysabri cause infections?
The immune system effects of TYSABRI may increase the risk for infections. In Study MS1 [see Clinical Studies (14.1)], certain types of infections, including pneumonias and urinary tract infections (including serious cases), gastroenteritis, vaginal infections, tooth infections, tonsillitis, and herpes infections, occurred more often in TYSABRI-treated patients than in placebo-treated patients [see Warnings and Precautions (5.1), Adverse Reactions (6.1)]. One opportunistic infection, a cryptosporidial gastroenteritis with a prolonged course, was observed in a patient who received TYSABRI in Study MS1.
Can tysabri cause urticaria?
Hypersensitivity reactions have occurred in patients receiving TYSABRI, including serious systemic reactions (e.g., anaphylaxis), which occurred at an incidence of <1%. These reactions usually occur within two hours of the start of the infusion. Symptoms associated with these reactions can include urticaria, dizziness, fever, rash, rigors, pruritus, nausea, flushing, hypotension, dyspnea, and chest pain. Generally, these reactions are associated with antibodies to TYSABRI. If a hypersensitivity reaction occurs, discontinue administration of TYSABRI, and initiate appropriate therapy. Patients who experience a hypersensitivity reaction should not be re-treated with TYSABRI. Hypersensitivity reactions were more frequent in patients with antibodies to TYSABRI compared to patients who did not develop antibodies to TYSABRI in both MS and CD studies. Therefore, the possibility of antibodies to TYSABRI should be considered in patients who have hypersensitivity reactions [see Adverse Reactions (6.2)]. Antibody testing: If the presence of persistent antibodies is suspected, antibody testing should be performed. Antibodies may be detected and confirmed with sequential serum antibody tests. Antibodies detected early in the treatment course (e.g., within the first six months) may be transient and may disappear with continued dosing. It is recommended that testing be repeated three months after an initial positive result to confirm that antibodies are persistent. Prescribers should consider the overall benefits and risks of TYSABRI in a patient with persistent antibodies. Patients who receive TYSABRI for a short exposure (1 to 2 infusions) followed by an extended period without treatment are at higher risk of developing anti-natalizumab antibodies and/or hypersensitivity reactions on re-exposure, compared to patients who received regularly scheduled treatment. Given that patients with persistent antibodies to TYSABRI experience reduced efficacy, and that hypersensitivity reactions are more common in such patients, consideration should be given to testing for the presence of antibodies in patients who wish to recommence therapy following a dose interruption. Following a period of dose interruption, patients testing negative for antibodies prior to re-dosing have a risk of antibody development with re-treatment that is similar to TYSABRI naïve patients [see Adverse Reactions (6.2)].
Is Tysabri available under REMS?
TYSABRI is available only through a restricted program under a REMS called the TOUCH® Prescribing Program because of the risk of PML [see Warnings and Precautions (5.1)].For prescribers and patients, the TOUCH® Prescribing Program has two components: MS TOUCH® (for patients with multiple sclerosis) and CD TOUCH® (for patients with Crohn's disease).
