Entyvio side effects

Vedolizumab is used to treat moderate to severe ulcerative colitis and Crohn’s disease in adults who have been intolerant to corticosteroids and TNF antagonists. It is also useful in patients in which TNF antagonists do not show desired efficacy.

In some patients, it also might be suggested as a first-line treatment. Although various researches have proved vedolizumab to be beneficial in pediatric ulcerative colitis and Crohn’s disease, it hasn’t been approved yet.

What is Entyvio (vedolizumab) and how it works?

Entyvio (vedolizumab) is a monoclonal antibody that binds to α4β7 integrin, which is expressed by gastrointestinal lymphocytes in inflammation. Vedolizumab binds to α4β7 integrin and inhibits its binding to the surface of mucosal endothelial cells. This phenomena aids in reducing inflammation.

Vedolizumab is a biological drug (can be created in living cells) it is a gut-selective integrin blocker. Unlike TNF antagonists, vedolizumab only acts on the gut rather than the whole body. Vedolizumab action varies among people. It may start its effects in six weeks in some people while in some people it might take as long as 14 weeks to act.

Serious Side Effects of Entyvio (vedolizumab):

Serious side effects are rare very rare. Some of them include:

Progressive Multifocal Leukoencephalopathy (PML):

  • Although it is extremely rare but it may be possible for a person to have Progressive Multifocal Leukoencephalopathy (PML). It is a rare but serious brain disorder caused by a virus. People with a weakened immune system are at greater risk of having PML. Symptoms include loss of balance, thinking problems, confusion, blurred vision or loss of vision, decreased strength, which may cause disability and even death. There is no treatment or cure available for PML.

Infections:

  • Some serious infections include pneumonia, anal abscess, gastroenteritis, and appendicitis. Microbial infections like Clostridium difficile infections, Shigella infections, Campylobacter infections, and Yersinia infections

Neoplasms:

  • Neoplasms including benign Skin Papilloma and Melanocytic Naevus and malignant neoplasms such as Basal Cell Carcinoma and Squamous Cell Carcinoma have an occurrence rate of <1% (0.3-0.4%)

Liver Injury:

  • Entyvio usage is associated with increased levels of transaminase and bilirubin. In patients with Ulcerative colitis and Crohn’s disease trials reported serious events of hepatitis within the first five weeks of administration of Entyvio although all the patients recovered by use of corticosteroids

Entyvio (Vedolizumab) Drug Interactions:

Following drugs must be avoided while on vedolizumab therapy

Natalizumab:

  • The combined use of vedolizumab with natalizumab increases the risk of PML that’s why these drugs must not be used together.

TNF antagonists:

  • TNF antagonists’ use with vedolizumab must be avoided to avoid serious infections due to drug interaction.

Live vaccines:

  • Live vaccination must not be done while on vedolizumab therapy.

Entyvio (vedolizumab) effect on pregnancy and fertility:

Vedolizumab is generally ranked in pregnancy B category drugs. There is no data available on the harmful effects of vedolizumab on fertility or during pregnancy. It is not recommended to use vedolizumab during pregnancy. Women of childbearing age must use a contraceptive with vedolizumab and should continue taking it even after five months of vedolizumab therapy. It is secreted in breastmilk that’s why it must be avoided in lactating women.

Overall Safety Profile of Entyvio (Vedolizumab):

Vedolizumab is the safest treatment for Inflammatory Bowel Disease (IBD).  The key advantage of this drug over others is that the other immunosuppressive agents affect the entire body while vedolizumab targets only the gut. That’s why its safety profile does not include the side effects associated with TNF inhibitors or corticosteroids.

The side effect profile of vedolizumab is superior to other immunosuppressive. No class of drugs is superior to vedolizumab in efficacy therefore it must be used as a first-line treatment.[Ref]

Conclusion:

Entyvio has a very low risk of side effects and a long-term safety profile which makes it the safest treatment for Inflammatory bowel disease. Although it might cause side effects in some people, it has the lowest rate of side effects among other agents.
