1. What Bortezomib Kern Pharma is and what it is used for

Bortezomib Kern Pharma contains the active substance bortezomib, a "proteasome inhibitor". Proteasomes play an important role in controlling cell function and growth.

Bortezomib can destroy cancer cells by interfering with their function.

Bortezomib Kern Pharma is used to treat multiple myeloma (a type of bone marrow cancer) in patients over 18 years of age:

• alone or with the medicines liposomal doxorubicin or dexamethasone, for patients whose disease is getting worse (in progression) after receiving at least one previous treatment and for those patients whose stem cell transplant did not work or is not suitable.
• in combination with the medicines melphalan and prednisone, for patients whose disease has not been previously treated and who are not suitable for high-dose chemotherapy before a stem cell transplant.
• in combination with the medicines dexamethasone or dexamethasone and thalidomide, in patients whose disease has not been previously treated and who receive high-dose chemotherapy before a stem cell transplant (induction treatment).

Bortezomib Kern Pharma is used to treat mantle cell lymphoma (a type of cancer that affects the lymph nodes) in patients over 18 years of age in combination with the medicines rituximab, cyclophosphamide, doxorubicin, and prednisone, in patients whose disease has not been previously treated and for those patients who are not considered suitable for a stem cell transplant.
