Thalidomide Pharmion(R) Receives Positive Opinion for Treatment of First-line Multiple Myeloma from European Medicines AgencyRecommendation based on study results demonstrating survival advantage of 18.4 months when added to standard therapy
First study to show survival advantage over European standard of care
BOULDER, Colo., Jan. 24 (HSMN NewsFeed) -- Pharmion Corporation (Nasdaq: PHRM ) today announced that the European Medicines Agency (EMEA) has issued a positive opinion to recommend approval of Thalidomide PharmionŽ for use in combination with melphalan and prednisone as first line treatment for patients with untreated multiple myeloma (MM), aged 65 years or older or ineligible for high dose chemotherapy. The marketing authorization application (MAA) for Thalidomide Pharmion was submitted to the EMEA in January 2007.
"We are very pleased with this recommendation by the EMEA for the approval of Thalidomide in the treatment of first line multiple myeloma, and clearly appreciate that the return of Thalidomide to Europe as an approved therapy represents a significant step toward the safe distribution of this important and widely used drug for patients with multiple myeloma," said Patrick J. Mahaffy, Pharmion's president and chief executive officer. "This has been a long and complex process and I would like to thank all of the participants in the dialogue that has led to this recommendation by the EMEA, which include European Thalidomide groups, patient organizations, the hematology community and the employees of Pharmion who made this happen. We have been and will remain committed to managing Thalidomide with the respect that its history requires."
The Marketing Authorization Application reviewed by the EMEA is based upon a clinical data package comprised of studies of nearly 1400 patients in total, including the Intergroupe Francophone du Myelome (IFM) 99-06 survival study. The three-arm study conducted by IFM demonstrated the superiority of melphalan/prednisone plus Thalidomide (MPT) over standard therapy of melphalan/prednisone (MP) or a combination of chemotherapies (vincristine/adriamycin/dexamethasone (VAD)) followed by melphalan and transplantation (MEL 100) in the treatment of newly diagnosed multiple myeloma patients, aged 65 to 75 who were ineligible for intensive bone marrow transplantation. A total of 447 patients were randomized to one of the three treatment arms. At final analysis, the overall median survival in the MPT arm was 51.6 months, compared to 33.2 and 38.3 months, respectively, for the MP and MEL 100 arms. The hazard ratios were 0.59 and 0.69, respectively. Thalidomide treatment was generally well-tolerated by the majority of patients. The most frequently reported adverse events associated with MPT included neutropenia, somnolence and constipation. The Thalidomide combination was also associated with a 5-10% greater risk of Grade 3 and 4 venous thromboembolism and peripheral neuropathy.
"Our study results demonstrate the profound impact on overall survival that the addition of Thalidomide to the standard of care can provide to patients with untreated multiple myeloma," said Professor Philippe Moreau, Professor of Clinical Hematology at Nantes Faculty of Medicine and Chairman of the Intergroupe Francophone du Myelome. "This recommendation recognizes the importance of the study results, opens drug access to all physicians and patients in Europe and provides great hope for patients with this devastating disease."
Multiple myeloma, the second most common cancer of the blood, affects approximately 82,000 people in the EU, and approximately 25,000 people in the EU are diagnosed with multiple myeloma each year.
Thalidomide Pharmion has been designated as an Orphan Medicinal Product in the EU for the treatment of multiple myeloma, which, if approved, entitles the drug to ten years of market exclusivity for the approved indications.
Thalidomide Pharmion must be prescribed and dispensed through the Thalidomide Pharmion Pregnancy Prevention Programme, a risk management plan that includes a number of actions intended to prevent pregnancies in women being treated with Thalidomide and exposure of unborn children to the medicine. Treatment with Thalidomide Pharmion, only available by prescription, will be initiated and monitored by a doctor who has experience in the treatment of multiple myeloma. A clear warning will be printed on the boxes containing the medicine, indicating that Thalidomide Pharmion causes birth defects and fetal death. Prior to the launch of Thalidomide Pharmion, Pharmion will provide healthcare professionals and patients with educational materials about the treatment-related risks and the precautions required to ensure the safe use of the product.
Thalidomide Pharmion is approved in Australia, New Zealand, Turkey, Israel, South Korea, Thailand and South Africa for the treatment of multiple myeloma after the failure of standard therapies.
Thalidomide is currently provided by Pharmion on a named patient/compassionate use basis in most of the EU and under an Autorisation Temporaire d'Utilisation (ATU) in France while the Company seeks an approval. Pharmion is the only provider of Thalidomide outside of the US with a comprehensive safety program in place.
The Company holds exclusive marketing and distribution rights from Celgene Corporation for Thalidomide in markets outside of North America, Japan and certain other Asian countries.
Thalidomide Pharmion warning:
Thalidomide is a powerful human teratogen, inducing a high frequency of severe and life threatening birth defects. Thalidomide must never be used by women who are pregnant or could become pregnant. The conditions of the Thalidomide Pharmion Pregnancy Prevention Programme must be fulfilled for all male and female patients
The common adverse reactions associated with the use of Thalidomide in combination with other anti-myeloma therapies are: deep vein thrombosis, constipation, peripheral oedema, tremor, dizziness, fatigue, asthenia, somnolence, peripheral neuropathy, neutropenia, lymphopenia, leucopenia, anaemia, thrombocytopenia, paraesthesia and dysaesthesia. Serious or severe reactions associated with Thalidomide use are: deep vein thrombosis and pulmonary embolism, bradycardia, cerebrovascular accident, peritonitis, orthostatic hypotension, and severe skin reactions including Stevens Johnson Syndrome and toxic epidermal necrolysis. Thromboprophylaxis should be used when Thalidomide is prescribed in combination with other anti-myeloma therapies. Peripheral neuropathy is a potentially severe, adverse effect of treatment with Thalidomide that may result in irreversible damage. Thalidomide may also potentially aggravate existing neuropathy and should therefore not be used in patients with clinical signs or symptoms of peripheral neuropathy unless the clinical benefits outweigh the risks. Symptoms may occur some time after Thalidomide treatment has been stopped and may resolve slowly or not at all. Thalidomide frequently causes drowsiness, somnolence and sedation. Patients should be instructed to avoid situations where drowsiness may be a problem.
About Multiple Myeloma
Multiple myeloma (also known as myeloma or plasma cell myeloma) is a cancer of the blood in which malignant plasma cells are overproduced in the bone marrow. Plasma cells are white blood cells that help produce antibodies called immunoglobulins that fight infection and disease. However, most patients with multiple myeloma have cells that produce a form of immunoglobulin called paraprotein (or M protein) that does not benefit the body. In addition, the malignant plasma cells replace normal plasma cells and other white blood cells important to the immune system. Multiple myeloma cells can also attach to other tissues of the body, such as bone, and produce tumors. The cause of the disease is unknown.
