Summary of the risk management plan (RMP) for Plegridy (peginterferon beta-1a)

This is a summary of the risk management plan (RMP) for Plegridy, which details the measures to be taken in order to ensure that Plegridy is used as safely as possible. For more information on RMP summaries, see here. This RMP summary should be read in conjunction with the EPAR summary and the product information for Plegridy, which can be found on Plegridy’s EPAR page.

Overview of disease epidemiology Plegridy is used to treat the relapsing-remitting form of multiple sclerosis (MS). MS is a disease in which the body’s immune system malfunctions and attacks parts of the central nervous system (the brain and spinal cord). This causes inflammation and destroys the protective sheath around the nerves, leading to progressive disability. Onset of MS is usually between the ages of 20 and 40 years, and rarely occurs in children or in adults 60 years and older. Approximately twice as many women than men have MS. About 85% of people with MS initially have the relapsing-remitting form, characterised by occasional flare-ups of the disease, called relapses, in between periods when the disease is inactive. About half of patients with MS relapses go on to develop progressive MS within 10 to 20 years after diagnosis. The total number of people with MS worldwide is estimated to be between 2 to 2.5 million, and approximately 93 of every 100,000 persons in Europe have MS.

Summary of treatment benefits Plegridy is a medicine that contains the active substance peginterferon beta-1a. It is available as a solution for injection under the skin. The peginterferon beta-1a in Plegridy is a ‘pegylated’ interferon (a protein naturally produced by the body), which is removed from the body at a slower rate than other interferons, allowing the medicine to be given less often. Plegridy was investigated in 1,516 patients in one main study, in which it was compared with placebo (a dummy treatment). Plegridy showed about a 30% reduction in the number of relapses in patients with relapsing-remitting MS compared with placebo, which is comparable to the effect of other MS medicines containing interferon beta, and is considered clinically relevant. When given every two weeks, Plegridy was also shown to slow down disease progression.

Unknowns relating to treatment benefits Peginterferon beta-1a has not been studied in patients under the age of 18 years or over the age of 65 years, in pregnant and/or breastfeeding women, or in patients with hepatic impairment (liver function problems). Furthermore, no direct comparison with non-pegylated interferons has been done, which should be considered when switching patients between pegylated and non-pegylated interferons. Peginterferon beta-1a will not cure MS, but rather improve its symptoms and it is not effective in patients with the progressive forms of MS.

Missing information Risk

What is known

Use in paediatric patients

Plegridy has not been studied in patients under 18 years of age.

Use in older patients

Plegridy has not been studied in patients over 65 years of age.

Effects on pregnancy and use in breastfeeding women

Treatment with Plegridy should not be started in pregnant patients. Patients who could get pregnant should use contraception during treatment with Plegridy. Patients planning to have a baby, or who become pregnant while using Plegridy, should tell their doctor to discuss possible treatment discontinuation. Patients wishing to breastfeed while using Plegridy should speak with their doctor first.

Use in patients with hepatic impairment (reduced liver function)

Plegridy has not been studied in patients with reduced liver function, as these patients were excluded from participating in clinical trials. Caution should be used and close monitoring should be considered when administering peginterferon beta-1a to patients with severe liver function problems. Patients

blood cell counts, as these patients were excluded from clinical trials. During treatment with Plegridy, patients may develop a low number of white blood cells or platelets, which can cause an increased risk of infection or bleeding. Patients should speak with their doctor, pharmacist or nurse before injecting peginterferon beta-1a if they experience infections or bleeding. They may get worse while using peginterferon beta-1a. The doctor may do blood tests from time to time to make sure that the patient’s blood cell counts are within the normal range.

Drug-drug interaction

No formal studies have been conducted on possible interactions between Plegridy and other medicines.

Summary of risk minimisation measures by safety concern All medicines have a summary of product characteristics (SmPC) which provides physicians, pharmacists and other healthcare professionals with details on how to use the medicine, and also describes the risks and recommendations for minimising them. Information for patients is available in lay language in the package leaflet. The measures listed in these documents are known as ‘routine risk minimisation measures’. The SmPC and the package leaflet are part of the medicine’s product information. The product information for Plegridy can be found on Plegridy’s EPAR page. This medicine has no additional risk minimisation measures.
