Glivec® approved in the US for five rare life-threatening disorders with limited treatment options


* Approvals represent the first time a regulatory authority has simultaneously approved one targeted medicine for five disorders
* Now approved for the solid tumor cancer, dermatofibrosarcoma protuberans
* US approval also granted for treatment of four blood diseases:
- Relapsed/refractory Philadelphia chromosome-positive acute lymphoblastic leukemia
- Myelodysplastic/myeloproliferative diseases
- Hypereosinophilic syndrome/chronic eosinophilic leukemia
- Aggressive systemic mastocytosis
* Multiple approvals in only five years highlight new approach of developing treatments based on common molecular pathways

Basel, October 20, 2006 - In another important milestone, Glivec® (imatinib)* has received US regulatory approval to help patients with five distinct and potentially life-threatening disorders, representing the first time that a regulatory authority has ever simultaneously approved one targeted medicine for so many disorders.

With today’s decision, and in only five years, Glivec has now been approved in the US for seven diseases, including two solid tumors and five blood disorders with molecular targets known to be inhibited by the drug.
All of the diseases covered in the new approval by the US Food and Drug Administration (FDA) are rare and potentially life threatening. For many of the patients who suffer from them, few if any approved treatments were available prior to Glivec.

“The effectiveness of Glivec in these five diseases further underscores how cancers and diseases of different origin and location can share common pathways that often respond to the same targeted treatment,” said Diane Young, MD, Vice President and global head of Clinical Development at Novartis Oncology. “These approvals further build and demonstrate our historical commitment to developing therapies for patients with rare diseases such as acromegaly, carcinoid syndrome and gastrointestinal stromal tumors.”

The FDA approvals are based on data from Novartis-sponsored clinical studies and clinical data from independent medical researchers showing the efficacy of Glivec in treating these diseases, in which there is a suggested connection between a Glivec-sensitive pathway and the disease.

Glivec targets the activity of proteins called tyrosine kinases that appear to play important roles within some cancer cells. Glivec has been shown to inhibit the function of the tyrosine kinase Bcr-Abl in patients with certain forms of blood cancer - Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) - and the receptor tyrosine kinase Kit in Kit-positive GIST (gastrointestinal stromal tumor).

Researchers have found Glivec also inhibits other tyrosine kinases, including platelet-derived growth factor receptor (PDGFR), which have been shown to be activated in disease pathways that underlie a number of rare hematologic diseases, as well as some solid tumors.

The new diseases for which Glivec received approval include one solid tumor and various rare blood disorders. The solid tumor is dermatofibrosarcoma protuberans (DFSP), a type of tumor that begins as a hard lump found in the skin of the chest, abdomen or leg. The four blood diseases include:
Relapsed/refractory Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL), a rapidly progressive blood cancer characterized by the presence of the Philadelphia chromosome
Certain forms of myelodysplastic/myeloproliferative diseases (MDS/MPD), which involve certain blood cells made in the bone marrow
Hypereosinophilic syndrome/chronic eosinophilic leukemia (HES/CEL), which is characterized by the persistent overproduction of eosinophils, a certain type of white blood cell
Aggressive systemic mastocytosis (ASM), which is marked by the presence of too many mast cells, a certain type of white blood cell.
An approval for newly diagnosed adult patients is still under review by the FDA. In the European Union (EU), Glivec was recently approved for treatment of certain patients with Ph+ ALL as well as for adult patients with a form of DFSP. The EU is also reviewing applications for approval of Glivec as a treatment for the three other diseases MDS/MPD, HES/CEL and ASM.

About Glivec
In addition to the new indications in the US, Glivec is approved in more than 90 countries including the US, EU and Japan for the treatment of all phases of Ph+ chronic myeloid leukemia (CML). Glivec is also approved in the EU, US and other countries for the treatment of patients with Kit (CD117)-positive gastrointestinal tumors (GISTs), which cannot be surgically removed and/or have already spread to other parts of the body (metastasized). In Japan, Glivec is approved for the treatment of patients with Kit (CD117)-positive GISTs. In the EU, Glivec is also approved for the treatment of adult patients with newly diagnosed Ph+ acute lymphoblastic leukemia (Ph+ ALL) in combination with chemotherapy and as a single agent for patients with relapsed or refractory Ph+ ALL, and for the treatment of adult patients with unresectable, recurrent and/or metastatic dermatofibrosarcoma protuberans (DFSP) who are not eligible for surgery.

The effectiveness of Glivec is based on overall hematologic and cytogenetic response rates and progression-free survival in CML, on hematological and cytogenetic response rates in Ph+ ALL, and on objective response rates in GIST and DFSP. There are no controlled trials demonstrating increased survival.

Glivec contraindications, warnings and adverse events
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.
The safety profile of Glivec was similar in all indications. The most common side effects included nausea, superficial edema, muscle cramps, skin rash, vomiting, diarrhea, abdominal pain, myalgia, arthralgia, hemorrhage, fatigue, headache, joint pain, cough, dizziness, dyspepsia and dyspnea, dermatitis, eczema, fluid retention, as well as neutropenia, thrombocytopenia and anemia. Glivec was generally well tolerated in all of the studies that were performed, either as monotherapy or in combination with chemotherapy with the exception of a transient liver toxicity in the form of transaminase elevation and hyperbilirubimaemia observed when Glivec was combined with high dose chemotherapy.

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, tumour hemorrhage/necrosis, hip osteonecrosis/avascular necrosis.
Glivec is contraindicated in patients with known hypersensitivity to imatinib or any of its excipients. Women of childbearing potential should be advised to avoid becoming pregnant while taking Glivec.
