Imatinib Normon is a treatment foradults and children for:

• Chronic Myeloid Leukemia (CML).CML is a cancer of the white blood cells. These white blood cells normally help the body fight infections. CML is a form of leukemia in which abnormal white blood cells (called myeloid cells) start to grow uncontrollably.

• Ph-positive Acute Lymphoblastic Leukemia (ALL Ph-positive). ALL is a cancer of the white blood cells. These white blood cells normally help the body fight infections. ALL is a form of leukemia in which abnormal white blood cells (called lymphoblasts) start to grow uncontrollably. Imatinib inhibits the growth of these cells.

Imatinib Normon is also a treatment for adults for:

• Myeloproliferative/Myelodysplastic Syndromes (MPN/ MDS).These are a group of blood disorders in which some blood cells start to grow uncontrollably. Imatinib Normon inhibits the growth of these cells in a certain subtype of these diseases.
• Hypereosinophilic Syndrome (HES) and/or Chronic Eosinophilic Leukemia (CEL). These are blood disorders in which some blood cells (called eosinophils) start to grow uncontrollably. Imatinib inhibits the growth of these cells in a certain subtype of these diseases.
• Gastrointestinal Stromal Tumors (GIST). GIST is a cancer of the stomach and intestine. It originates from uncontrolled cellular growth of the supporting tissues of these organs.
• Dermatofibrosarcoma Protuberans (DFSP).DFSP is a cancer of the tissue under the skin in which some cells start to grow uncontrollably. Imatinib inhibits the growth of these cells.

In the rest of this prospectus, these abbreviations are used when referring to these diseases.
