Does Ocrevus Cause Breast Cancer

What Should I Tell My Healthcare Provider Before Using Ocrevus

Mayo Clinic Explains Breast Cancer

Before receiving Ocrevus, tell your healthcare provider about all of your medical conditions, including if you:

  • have ever taken, take, or plan to take medicines that affect your immune system, or other treatments for MS. These medicines could increase your risk of getting an infection.
  • have ever had hepatitis B or are a carrier of the hepatitis B virus.
  • have had a recent vaccination or are scheduled to receive any vaccinations.
  • You should receive any required live or live-attenuated vaccines at least 4 weeks before you start treatment with Ocrevus. You should not receive live or live-attenuated vaccines while you are being treated with Ocrevus and until your healthcare provider tells you that your immune system is no longer weakened.
  • When possible, you should receive any non-live vaccines at least 2 weeks before you start treatment with Ocrevus. If you would like to receive any non-live vaccines, including the seasonal flu vaccine, while you are being treated with Ocrevus, talk to your healthcare provider.
  • If you have a baby and you received Ocrevus during your pregnancy, it is important to tell your babys healthcare provider about receiving Ocrevus so they can decide when your baby should be vaccinated.
  • are breastfeeding or plan to breastfeed. It is not known if Ocrevus passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you take Ocrevus.
  • Breast Cancer Drug Shows Potential To Repair Myelin

    Researchers at the University of Cambridge have found a new way to repair myelin using a well-established treatment for breast cancer.

    Tamoxifen has been used to treat breast cancer since the early 1970s, but research has revealed some previously unknown benefits of the treatment.

    Dr Mark Kotter, who led the project, said:

    Were very excited about our findings. We looked at six existing drugs for a range of conditions as part of our work. What we discovered was that Tamoxifen can enhance myelin repair in MS by encouraging the brains own stem cells to regenerate myelin.

    Does Ocrevus Cause Weight Gain Or Weight Loss

    No, Ocrevus isnt likely to cause weight changes. Weight gain and weight loss werent reported as side effects in clinical studies of the drug.

    Keep in mind that Ocrevus may cause edema in the arms or legs, and this can lead to a small amount of weight gain. If you have edema with Ocrevus, talk with your doctor about ways to ease this side effect. They may prescribe a medication to help reduce your swelling.

    Ocrevus And Other Drugs That Weaken Your Immune System

    While taking Ocrevus, you shouldnt take other medications that may weaken your immune system.

    This is because Ocrevus weakens your immune system. If you take it with another medication that also has this effect, your immune system may get too weak. This could make your body unable to fight infections.

    Examples of drugs that can weaken your immune system include corticosteroids . Prednisone and methylprednisolone are types of corticosteroids.

    Other MS medications may also affect your immune system, so you should talk with your doctor if youre switching from another MS medication to Ocrevus.

    They may want you to wait to start Ocrevus. This is because some MS medications may last weeks or months in your body. Your doctor will be able to help you determine how long to wait between stopping your old MS medication and starting Ocrevus.

    Examples of MS medications that have an effect on your immune system for a long period of time include:

    Talk with your doctor about any other medications youre taking before you start Ocrevus.

    Upper And Lower Respiratory Infections


    Upper and lower respiratory infections are two of the most common side effects reported by people taking Ocrevus in clinical trials. Upper respiratory infections were more common than lower respiratory infections .

    Symptoms of a respiratory infection can include:

    • cough
    • fever
    • chills

    Most people who had an upper or lower respiratory infection while taking Ocrevus had mild cases. But, rarely, these infections can be severe.

    What you can do

    If you have an active infection before starting Ocrevus, the infection will need to be treated, or youll have to wait until it resolves before starting Ocrevus. This includes an upper or lower respiratory infection.

    If you develop symptoms of an infection while taking Ocrevus, call your doctor. Theyll likely want to evaluate your symptoms further. If they diagnose an infection, they may prescribe antibiotics to treat it. They may also recommend treatments for any symptoms youre experiencing.

    A simple but effective way to help prevent infection includes washing your hands. You should do this regularly, especially during Ocrevus treatment. For tips on how to properly wash your hands, check out this article.

    What Every Ms Patient Should Know About Ocrevus And Its Use

    With the recent approval of Ocrevus for both primary progressive and relapsing multiple sclerosis , interest in the medication is peaking. To help readers of Multiple Sclerosis News Today better understand this new medication and how it works, as well issues dealing with access, use, and potential side effects, here is a summary of the most relevant information now available about Ocrevus.

    What Other Drugs Will Affect Ocrevus

    Tell your doctor about all other medicines you have recently used to treat multiple sclerosis.

    Other drugs may interact with ocrelizumab, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.

    Ocrevus works in MS by targeting a specific protein, called CD20 that exists on the surface of immature and mature B-lymphocytes. B lymphocytes are a type of white blood cell which are thought to contribute to the development of MS in several different ways, including secreting antibodies during an MS attack that cause inflammation which damages the myelin coating around nerve cells in the brain and spinal cord. When Ocrevus binds to CD20, it causes B-cells to self-destruct or disintegrate, which reduces the number of MS relapse and the rate of disability progression. Continue reading

    B Cell Therapies: Rituximab Ocrelizumab

    The Tonight Show Starring Jimmy Fallon : KNTV : November 18, 2020 11 ...

    Rituximab and ocrelizumab, anti-CD20 B cell depleting monoclonal antibodies, have become critical agents in the management of MS, underlying the importance of B cells in the pathophysiology of MS. Rituximab is a chimeric monoclonal antibody targeted against CD20, while ocrelizumab is a humanized anti-CD20 agent. Although not FDA approved in demyelinating diseases, rituximab is widely used in the treatment of MS and Neuromyelitis Optica. Ocrelizumab was FDA approved in 2017 for RRMS and primary progressive multiple sclerosis based on two large phase III trials . Further anti-CD20 agents, currently in late stages of the development pipeline, include ofatumumab and ublituximab. The anti-CD20 therapies lead to elimination of CD20 expressing pre-B cells and mature lymphocytes via a variety of mechanisms, including antibody-dependent cellular cytotoxicity , antibody-dependent cellular phagocytosis, complement-dependent cytotoxicity , cell death via apoptosis and decreased antibody production .

    Despite the success of anti-CD20 monoclonal antibodies in cancer treatment, there are also several cancers associated with the use of anti-B cell therapies. For example, ocrelizumab was associated with several cases of malignancy in clinical trials, including cases of renal cancer, melanoma, and breast cancers. Overall, 4 malignancies were reported in OPERA 1 trial in RRMS patients and 11 malignancies were reported in PPMS patients in the ORATORIO trial .

    Is Ocrevus Chemotherapy

    No, Ocrevus is not chemotherapy. It belongs to a class of drugs called monoclonal antibodies.

    Ocrevus works by decreasing the activity of your immune system and stopping it from attacking your body. Ocrevus targets specific cells called B cells. It decreases the number of B cells in your body, which can help relieve your MS symptoms.

    How Ocrevus Is Given

    Ocrevus is given as an intravenous infusion. This means a needle goes into a vein in your arm and delivers the medication slowly over time. Getting the medication slowly lowers your risk for having a reaction to the drug.

    Your first dose of Ocrevus will be given over the course of 2.5 hours or longer. Then, youll get a second dose of medication 2 weeks after your first dose. This infusion will also be given over 2.5 hours or longer.

    After your first two doses of medication, you only need to get one dose every 6 months. These doses will be given over the course of 3.5 hours or longer.

    Your doctors office will work with you to make sure the infusion appointments fit your schedule. To help make sure you dont miss an appointment, try setting a reminder on your phone.

    Is Ocrevus Used For Ms

    Ocrevus is prescribed to treat certain types of multiple sclerosis in adults.

    MS is a condition that causes your immune system to attack the protective covering of your brain and spinal cord. This can cause swelling in your brain and spinal cord, which interrupts the communication between your brain and body.

    Below are brief descriptions of each condition Ocrevus is used to treat.

    • Clinically isolated syndrome . With CIS, you experience MS symptoms for at least 24 hours. Although CIS is usually the first sign of MS, it often occurs before an official MS diagnosis.
    • Relapsing-remitting MS. Relapsing-remitting MS has repeated episodes of relapse and remission .
    • Active secondary progressive MS. Active secondary progressive MS usually starts as relapsing-remitting MS. But over time, your MS symptoms continue to worsen.
    • Primary progressive MS . If you have PPMS, you have continued worsening MS symptoms without ever having periods of remission.

    What If I Miss A Dose

    Infections Such As Respiratory Or Skin Infections

    Ocrevus weakens part of your immune system . As a result, it can increase your risk for infections. For example, you may have an increased risk for herpes infection .

    In studies, infections were commonly reported in people using Ocrevus. Types of infections reported in people treated with Ocrevus include:

    • blisters or spots

    Most infections reported in studies, including herpes infections, were mild to moderate in severity.

    But in rare cases, infections can be severe. Since Ocrevus has been on the market, serious cases of herpes infections have been reported in some people receiving this treatment. These include widespread skin or soft tissue infections, as well as herpes infections of the eyes or brain.

    What might help

    Here are a few tips that may help prevent you from getting an infection:

    • Wash your hands or use hand sanitizer frequently, especially if youve been in a public place.
    • Avoid crowds when possible.
    • Stay away from people who are sick.
    • Dont share facecloths, towels, lip balms, or lipsticks with others.
    • Avoid kissing or sexual contact with someone who has an active herpes infection.
    • Eat a healthy diet containing plenty of fruit and vegetables.
    • Make sure youre up to date with immunizations before you start Ocrevus treatment.

    See your doctor right away if you have an infection that starts to get worse or doesnt get better after about a week. You should also see your doctor right away if you have symptoms of a more serious herpes infection. These may include:

    Convenience A Benefit Of Ocrevus

    Another thing that makes Ocrevus appealing is the convenience factor. Existing DMTs are administered via pills, injections, or infusions, some requiring daily dosing, some weekly, some every two weeks, and some monthly. Ocrelizumab is given as an infusion twice a year.

    Ocrevus has proved to be very convenient, says Ellen Lathi, MD, the director of the Elliot Lewis Center for Multiple Sclerosis in Wellesley, Massachusetts. Because you only need an infusion every six months, it allows patients to forget they have MS for 363 days of the year.

    Risks and side effects of Ocrevus are comparable to those of other DMTs, though some research has suggested Ocrevus may raise the risk of breast cancer. As a precaution, women taking the medication are strongly advised by their physicians to stay up-to-date on mammograms.

    Why Are These Studies Important

    Life expectancy for people living with MS has improved over time. However, on average, people with MS live 6-7 years less than the general population. Their most common cause of death is related to MS. However, depending on the study, cancer has been reported as the second or third most common cause of death in adults with MS. Does MS affect cancer outcomes? A better understanding of the impact of MS on cancer is needed to help patients and their healthcare providers make informed decisions about their treatment.

    Breast Cancer Survival in Multiple Sclerosis

    • Women with MS were more likely to die from any cause after a breast cancer diagnosis compared to women without MS.
    • The reason for this difference is unknown. Possible reasons may include disability in women with MS. For example, women who have more disability due to MS may face barriers to treatment, may receive less aggressive treatment or may be more susceptible to complications from treatment or other factors that decreased their overall survival. Another possibility is that breast cancer or treatment for it worsened MS.
    • Women with MS were no more likely to die from breast cancer compared to women without MS.

    Colorectal Cancer Survival in Multiple Sclerosis

    • People with MS were more likely to die from any cause after a colorectal cancer diagnosis compared to people without MS but only in the first 6-12 months after that diagnosis.
