Basel, July 25, 2007 - Switzerland has granted the first worldwide approval for Tasigna® (nilotinib), a potent and novel targeted cancer therapy for patients with a form of the life-threatening blood cancer chronic myeloid leukemia (CML) who are resistant or intolerant to treatment with Glivecâ (imatinib) - the leading therapy for CML patients also developed by Novartis.
The approval of Tasigna came after an accelerated review by the Swiss health authority Swissmedic based on positive findings from a pivotal Phase II trial, Trial results showed high response rates in these patients with a generally well-tolerated, manageable safety profile.
Taken twice-daily, Tasigna inhibits production of cancer cells containing an abnormal chromosome by targeting the Bcr-Abl protein. This protein, which is produced by cells containing the abnormal Philadelphia chromosome, is recognized as the key driver of the overproduction of cancer-causing white blood cells in patients with CML.
In clinical trials, Tasigna reduced or eliminated this abnormal chromosome in 42% of Glivec-resistant patients with Philadelphia chromosome-positive (Ph+) CML in the chronic phase of the disease, as well as in 31% of patients in the accelerated phase of the disease.
"While over 90% of patients on Glivec survive after five years, we focused on helping the small percentage of patients who developed resistance or intolerance to Glivec, which led to the discovery of Tasigna," said Dr. Daniel Vasella, Chairman and CEO of Novartis. "I am pleased that we set a record of less than five years from synthesis to market, rapidly bringing Tasigna - our second-generation, more selective and more potent Bcr-Abl tyrosine kinase inhibitor - to those patients who need it."
Additional regulatory decisions on Tasigna are expected in the US and Europe later this year, while a regulatory submission was completed in Japan during the second quarter of 2007. In the US, the Food and Drug Administration requested on July 16 a three-month extension in the regulatory review period.
Also planned for 2007 are Phase III studies involving Tasigna in CML patients responding sub-optimally to other therapies as well as newly-diagnosed CML patients. A registration study is already underway in patients with gastrointestinal stromal tumors (GIST), which can also be treated with Glivec in certain countries.
Recent landmark clinical trial results for Glivec showed that nearly 90% of newly-diagnosed chronic phase Ph+ CML adults patients treated with Glivec were alive after five years, but some develop resistance or cannot tolerate this therapy.
Applying key learnings from Glivec, a team of Novartis scientists created Tasigna in August 2002, just a year after the launch of Glivec. Tasigna was specifically designed to target Bcr-Abl more potently and preferentially without adding new mechanisms of action that might cause additional side effects. Tasigna moved from synthesis to its first regulatory approval in less than five years.
"The speed of developing Tasigna reflects our passion to help cancer patients," said David Epstein, President and CEO of Novartis Oncology. "A designer cancer treatment, Tasigna also highlights our leadership in targeted therapies."
Chronic myeloid leukemia is one of the four most common types of leukemia, responsible for about 15% of all leukemia cases worldwide, and caused by an overproduction of immature white blood cells. Approximately 95% of CML patients have the Philadelphia chromosome.
Approval based on impressive Phase II results Tasigna has been approved for use in the treatment of chronic or accelerated phase of Ph+ CML patients resistant to, or experiencing significant toxicity during treatment with Glivec. The Swiss filing was based on an open-label Phase II study designed to evaluate the safety and efficacy of Tasigna in Glivec-resistant or -intolerant patients with Ph+ CML in chronic and accelerated phase. Efficacy was measured by cytogenetic response, i.e. reduction or elimination of the Ph+ chromosome, and hematologic response, i.e. normalization of white blood cell counts..
Among 132 patients with chronic phase disease, major cytogenetic response was observed in 55 patients (42%) after a median of 7.7 months' treatment. Among 64 patients with accelerated phase disease, major cytogenetic response was observed after a median of five month' follow-up in 20 (31%).
Longer-term data from this pivotal Phase II trial presented last month at the American Society of Clinical Oncology annual meeting showed even further positive results.
Tasigna safety information The safety of Tasigna was studied in 438 patients. The most frequent Grade 3 or 4 adverse events for Tasigna were primarily hematological in nature and included neutropenia and thrombocytopenia. Elevations were seen in bilirubin, liver function tests, lipase enzymes and blood sugar, which were mostly transient and resolved over time. These cases were easily managed and rarely led to discontinuation. Pancreatitis was reported in less than 1% of cases. The most frequent non-hematologic drug-related adverse events were rash, pruritus, nausea, fatigue, headache, constipation, and diarrhea. Most of these adverse events were mild to moderate in severity.
Tasigna should be used with caution in patients who have or may develop prolongation of QTc. These include patients with abnormally low potassium or magnesium levels, patients with congenital long QT syndrome, patients taking anti-arrhythmic medicines or other drugs that may lead to QT prolongation, and cumulative high-dose anthracycline therapy. Low levels of potassium or magnesium must be corrected prior to Tasigna administration.
The bioavailability of Tasigna is increased by food. Tasigna should not be taken in conjunction with food and should be taken two hours after a meal. No food should be consumed for at least one hour after the dose is taken.
About Glivec Glivec is approved in more than 90 countries including the US, EU and Japan for the treatment of all phases of Ph+ CML. Glivec is also approved in the EU, US and other countries for the treatment of patients with Kit (CD117)-positive gastrointestinal tumors (GIST), which cannot be surgically removed and/or have already spread to other parts of the body (metastasized). Glivec has also been approved in various countries for use in treating patients with certain rare types of cancer.
The majority of patients treated with Glivec in clinical trials experienced adverse events at some time. Most events were of mild to moderate grade and treatment discontinuation was not necessary in the majority of cases.
Rare/serious adverse reactions include: sepsis, pneumonia, depression, convulsions, cardiac failure, thrombosis/embolism, ileus, pancreatitis, hepatic failure, exfoliative dermatitis, angioedema, Stevens-Johnson syndrome, renal failure, fluid retention, edema (including brain, eye, pericardium, abdomen and lung), hemorrhage (including brain, eye, kidney and gastrointestinal tract), diverticulitis, gastrointestinal perforation, tumor hemorrhage/ necrosis, hip osteonecrosis/avascular necrosis.
Patients with cardiac disease or risk factors for cardiac failure should be monitored carefully and any patient with signs or symptoms consistent with cardiac failure should be evaluated and treated. Cardiac screening should be considered in patients with HES/CEL, and patients with MDS/MPD with high level of eosinophils (echocardiogram, serum troponin level).
