Bortezomib SUN in combination with dexamethasone, or with dexamethasone and thalidomide, is indicated for the induction treatment of adult patients with previously untreated multiple myeloma who are eligible for high-dose chemotherapy with haematopoietic stem cell transplantation.

Bortezomib SUN in combination with rituximab, cyclophosphamide, doxorubicin and prednisone is indicated for the treatment of adult patients with previously untreated mantle cell lymphoma who are unsuitable for haematopoietic stem cell transplantation.

What is Bortezomib Sun and what is it used for?

Bortezomib Sun is a cancer medicine used to treat multiple myeloma, a blood cancer, in the following groups of patients:

  • adults whose disease is getting worse after at least one other treatment and who have already had, or cannot undergo, blood stem-cell transplantation. Bortezomib Sun is either used on its own in these patients or in combination with pegylated liposomal doxorubicin or dexamethasone;
  • previously untreated adults who cannot have high-dose chemotherapy with blood stem-cell transplantation. In these patients, Bortezomib Sun is used in combination with melphalan and prednisone;
  • previously untreated adults who are going to receive high-dose chemotherapy followed by blood stem-cell transplantation. In this group of patients, Bortezomib Sun is used in combination with dexamethasone, or with dexamethasone plus thalidomide.

Bortezomib Sun is also used to treat mantle cell lymphoma, another blood cancer, in untreated adults who cannot have blood stem-cell transplantation. For mantle cell lymphoma, Bortezomib Sun is used in combination with rituximab, cyclophosphamide, doxorubicin and prednisone.

Bortezomib Sun is a ‘generic medicine’. This means that Bortezomib Sun is similar to a ‘reference medicine’ already authorised in the European Union (EU) called Velcade.

Bortezomib Sun contains the active substance bortezomib.

How is Bortezomib Sun used?

The medicine can only be obtained with a prescription and treatment should only be started and given under the supervision of a doctor who has experience in the use of cancer chemotherapy.

Bortezomib Sun is available in vials as a 3.5 mg powder to be made up into a solution for injection into a vein or under the skin. Bortezomib Sun must not be given by other routes.

The recommended dose is calculated using the patient’s height and weight). When given into a vein, the solution is injected through a catheter (a thin sterile tube). At least 72 hours must pass between two doses of Bortezomib Sun. When injected under the skin, it is given in the thigh or abdomen (tummy).

Doses of Bortezomib Sun are given with rest periods between doses, in treatment cycles of three to six weeks depending on whether Bortezomib Sun is given alone or in combination with other medicines. If a patient develops severe side effects, treatment must be discontinued, delayed or the dose adjusted.

Patients with moderate or severe liver problems should be treated with lower doses. For more information on the use of Bortezomib Sun see the summary of product characteristics (also part of the EPAR).

How does Bortezomib Sun work?

The active substance in Bortezomib Sun, bortezomib, is a proteasome inhibitor. It blocks proteasome, which is a system in cells that breaks down proteins that are no longer needed. Blocking the proteasome system causes the cell to die. Cancer cells are more sensitive than normal cells to the effects of proteasome inhibitors like bortezomib.

How has Bortezomib Sun been studied?

The company provided data from the published literature on bortezomib. No additional studies were needed as Bortezomib Sun is a generic medicine that is given by injection and contains the same active substance as the reference medicine, Velcade.

What are the benefits and risks of Bortezomib Sun?

Because Bortezomib Sun is a generic medicine, its benefits and risks are taken as being the same as the reference medicine’s.

Why is Bortezomib Sun approved?

The Agency’s Committee for Medicinal Products for Human Use (CHMP) concluded that, in accordance with EU requirements, Bortezomib Sun has been shown to be comparable to Velcade. Therefore, the CHMP’s view was that, as for Velcade, the benefit outweighs the identified risk. The Committee recommended that Bortezomib Sun be approved for use in the EU.

What measures are being taken to ensure the safe and effective use of Bortezomib Sun?

The company that markets Bortezomib Sun will supply educational material to healthcare professionals on making up and giving the injection, calculating the dose, and prescribing and giving the correct treatment for patients receiving blood stem-cell transplantation.

Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Bortezomib Sun have also been included in the summary of product characteristics and the package leaflet.
