Transcription

1 EMA/2497/2016 Summary of the risk management plan (RMP) for Tagrisso (osimertinib) This is a summary of the risk management plan (RMP) for Tagrisso, which details the measures to be taken in order to ensure that Tagrisso 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 Tagrisso, which can be found on Tagrisso s EPAR page. Overview of disease epidemiology Tagrisso is a cancer medicine used to treat a type of lung cancer called non-small cell lung cancer. Approximately 85% to 90% of all lung cancers are non-small cell lung cancers (NSCLC). Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer-related deaths worldwide. NSCLC is more common in the developed world (Europe, North America and Eastern Asia) and has been reported to occur in around 80 men in every 100,000 per year and around 50 women in every 100, 000 per year. Tagrisso is used in patients with NSCLC with a specific mutation ( T790M ) in the EGFR gene. These mutations have been found in 10% to 20% of white patients and in 30% to 60% of patients with NSCLC who are of East Asian origin. These mutations are more frequently seen in patients who have already been treated with medicines called EGFR tyrosine kinase inhibitors. Most diagnoses of lung cancer are in patients aged over 50 years. The most important risk factors for the development of NSCLC with a T790M mutation in the EGFR gene are prior treatment with an EGFR tyrosine kinase inhibitor, female sex, not smoking and being of East Asian origin. Summary of treatment benefits Tagrisso contains the active substance osimertinib. It has been investigated in two main studies involving 411 patients who had the T790M mutation and in whom the disease progressed despite previous treatment with EGFR tyrosine kinase inhibitors. In both studies, which were still ongoing at the time of Tagrisso s initial evaluation, the medicine was not compared with any other treatment. The main measure of effectiveness was the proportion of patients who responded to treatment (objective response rate) and whose tumour shrank, which was assessed using body scans and standardised criteria for solid tumours. Combining both studies, the overall response rate at the time of analysis was 66% (263 out of 398 patients) and preliminary data suggest that the average length of response was 8.5 months. Page 1/13

2 Unknowns relating to treatment benefits The safety and effectiveness of Tagrisso has not been studied in patients under 18 years. In addition, as very few patients studied had significant liver or kidney problems, the safety and effectiveness of Tagrisso in these patients not yet fully established. Animal studies have shown that Tagrisso adversely affects the survival and the development of the fetus. Pregnant or breastfeeding women were therefore excluded from clinical trials. Women should not breastfeed or become pregnant whilst taking Tagrisso. Summary of safety concerns Important identified risks Risk What is known Preventability Serious inflammation of the lungs called interstitial lung disease (ILD) Problems with the electrical activity of the heart (QT prolongation) ILD is difficult to diagnose, but if left untreated, it can be life threatening or fatal. In clinical studies of Tagrisso, 2.7% of patients have reported ILD-or ILD-like events, some of which have been fatal (4 out of 1,221 patients). ILD has also been reported with other cancer medicines. No specific risk factors for the development of ILD in Tagrisso - treated patients have yet been identified. Studies have shown that treatment with Tagrisso can have a small effect on the electrical activity of the heart, known as the QT interval. However, the size of the effect is small and is not thought to cause any serious health problems (e.g abnormal heart beat rhythm). Patients and doctors should be aware of the risks of ILD, and the Summary of Product Characteristics (SmPC) and package leaflet (PL) contain information about this possible side effect. Any Tagrisso-treated patient who experiences shortness of breath, cough or fever should be investigated for possible ILD. Treatment with Tagrisso must be interrupted until the symptoms can be investigated. Treatment with Tagrisso must be permanently stopped if ILD is diagnosed. Detection and treatment at an early stage could minimise the effects of ILD. Patients and doctors should be aware of the risks of QT prolongation, especially in patients who may be at an increased risk of developing serious heart problems (e.g. abnormal heart beat rhythm).when possible, Tagrisso should be avoided in patients with congenital long QT syndrome. Appropriate monitoring (such as measuring the elctrical activity of the heart (ECG) and electrolytes) should be done in patients with congestive heart failure, electrolyte abnormalities and when medicines known to prolong the QT interval are given in combination with Tagrisso.

3 Important potential risks Risk Effects on development and survival of the unborn child What is known There are no data from the use of Tagrisso in pregnant women. Women who are capable of getting pregnant must not become pregnant while taking this medicine and must not start the treatment if they are already pregnant, as Tagrisso could cause harm to the unborn baby (fetus). Animal studies have shown that Tagrisso adversely affects the development and the survival of the fetus. Therefore women of childbearing potential must use effective contraception during treatment with Tagrisso and for at least 2 months after receiving the last dose of Tagrisso. Men must also use effective contraception during treatment with Tagrisso and for 4 months after receiving the last dose of Tagrisso. so that their partners do not become pregnant. Serious skin reactions Severe diarrhoea Eye disorders Liver disorders Patients have reported rash, itching and other similar side effects in clinical trials with Tagrisso. Most of these events tended to be mild or moderate, with only 0.5% of cases considered severe. To date, there have been no reports of certain severe adverse events affecting the skin (e.g. severe blistering, severe exfoliation (flaking of the skin)) that are a concern for other medicines with a similar mechanism of action to Tagrisso. Severe diarrhoea can be a concern for patients taking medicines with a similar mechanism of action to Tagrisso. Diarrhoea has been reported by patients taking Tagrisso, but in most cases it tends to be mild or moderate and does not require any form of treatment. Severe diarrhoea has only been reported in 1% of patients. Patients have reported adverse effects affecting the eye in studies with Tagrisso. These events tended to be mild or moderate in severity.. To date, there have been no reports of certain severe adverse events (e.g. corneal erosion, corneal ulceration), which are a concern for other medicines with a similar mechanism of action to Tagrisso. Changes in the liver function laboratory tests have been reported for patients in clinical trials with Tagrisso. These changes tended to be mild or moderate in nature, and, for a significant number of patients, may be related to the presence of pre-existing lung cancer spreading to the liver. Missing information Risk Long-term exposure to Tagrisso Use in women who are breastfeeding What is known There is limited information on patients who have used Tagrisso treatment for longer than a year, and therefore side effects following long-term treatment with Tagrisso are not known. In the main clinical studies, 23.6% of patients had received Tagrisso treatment for longer than 9 months. Animal studies show that Tagrisso may pass into breast milk. There is no evidence to show that this causes harm to the child but mothers should not Page 3/13

4 Risk What is known breastfeed while taking Tagrisso. severely reduced kidney function moderately or severely reduced liver function Use in patients capable of only limited self-care or patients who cannot carry out any self-care Use in patients who have lung cancer that has spread to the brain (brain metastases) and who have active symptoms (e.g. headaches, behavioural or personality changes, nausea and vomiting, seizures, etc.) Interaction between Tagrisso and medicines, called non- CYP3A4 mediated PXR substrates that may affect the way Tagrisso or the other medicines work Potential for transporter inhibition (interaction between Tagrisso and medicines that are distributed in the body by transporter proteins that may affect the way Tagrisso or the other medicines work) Potential for P-gp inhibition (Taking Tagrisso with certain other medicines Only a small number of patients with severely reduced kidney function were included in the main clinical trials. The data on these patients is therefore limited. Only a small number of patients with moderately reduced liver function were included in the main clinical trials. The data on these patients is therefore limited. Tagrisso has not been studied in patients who are not able to fully take care of themselves; patients not able to fully take care for themselves, patients who are confined to a bed or chair for more than 50% of waking hours or patients who are completely disabled who cannot carry out any self-care and are totally confined to bed or a chair. Patients whose lung cancer had spread to the brain and caused recent symptoms were not included in the main clinical studies. It is therefore not known how these patients will tolerate Tagrisso treatment; however no major difference in the safety and effectiveness of this treatment is expected. It is not known whether medicines called non-cyp3a4 mediated PXR substrates affect the amount of Tagrisso in the body. It is also not known whether Tagrisso affect the amount of these medicines in the body. This in turn may increase the chance of side effects, or affect the effectiveness of these medications. Clinical studies with Tagrisso have shown an interaction is unlikely to occur, however further studies are underway to obtain additional information. It is not known whether taking Tagrisso with medicines that are distributed in the body by transport proteins affect the way Tagrisso or the other medicines work. This in turn may increase the chance of side effects, or affect the effectiveness of these medications. Clinical studies with Tagrisso have shown this is unlikely to occur, however further studies are underway to obtain additional information. It is not known whether taking Tagrisso with other medicines that are distributed in the body by the transporter protein P-gp affect the amount of these medicines. This in turn may increase the chance of side effects, or affect the effectiveness of these medications. Clinical studies with Tagrisso Page 4/13

5 Risk (those which are distributed in the body by transporter proteins [P-gp] may affect the way Tagrisso or the other medicine works) Absolute bioavailability of Tagrisso (amount of active substance that becomes available in the bloodstream after taking a dose of Tagrisso) Use in elderly patients 75 years or above What is known have shown this is unlikely to occur, however further studies are underway to obtain additional information. The absolute bioavailability of Tagrisso has not yet been determined. Further information is needed to further understand how the body absorbs the medicine and how much active substance becomes available in the bloodstream after taking Tagrisso. There is very limited information available for patients aged 75 years or older who have taken Tagrisso. It is therefore not known how these patients will tolerate Tagrisso treatment; however no major difference in the safety and effectiveness of this treatment is expected. 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 Tagrisso can be found on Tagrisso s EPAR page. This medicine has no additional risk minimisation measures.
