Imatinib Krka d.d. is a medication that contains an active ingredient called imatinib. This medication acts by inhibiting the growth of abnormal cells in the following diseases, which include some types of cancer.

Imatinib is a treatment for adults and children for:

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

• Acute Lymphoblastic Leukemia with Philadelphia chromosome positive (ALL Ph-positive).Leukemia is a cancer of the white blood cells. These white blood cells normally help the body fight infections.Acute lymphoblastic leukemia 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 is also a treatment for adults for:

• Myeloproliferative/Myelodysplastic Syndromes (MPN/ MDS).These are a group of blood diseases in which some blood cells start to grow uncontrollably. Imatinib 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 diseases 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 an uncontrolled growth of the supporting tissue 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, abbreviations will be used when referring to these diseases.
