What is Venclexta/Venclyxto (venetoclax) for?
Venclexta/Venclyxto (venetoclax) is a B-Cell lymphoma-2 (BCL-2) inhibitor (chemotherapy) indicated as monotherapy for the treatment of people with chronic lymphocytic leukemia (CLL), with or without the 17p deletion, who have received at least one prior therapy1,2,3,4. The presence of 17p deletion can be assessed using specifically designed diagnostic tools3.
Venclexta/Venclyxto (venetoclax) in combination with rituximab is indicated for the treatment of adult patients with CLL who have received at least one prior therapy2,3,4. Venetoclax is marketed in the USA, Canada and Australia under the name Venclexta1,3,4, and in the European Union under the name Venclyxto2.
How does Venclexta/Venclyxto (venetoclax) work?
CLL is a slow-growing disease in which too many immature lymphocytes (white blood cells) accumulate in the blood and bone marrow5. About 10% of patients with untreated CLL and approximately 20% of patients with relapsed CLL have a particular chromosomal abnormality (17p deletion)6 that is related to a specific type of CLL named B-Cell lymphoma 2 (BCL-2).
Patients with CLL who have a 17p deletion lack a portion of the 17th chromosome the gene involved with the identification and elimination of faulty cells can be found7. This gene thus acts to suppress cancer growth. In the presence of a 17p deletion, healthy cells are unable to use this identification/elimination pathway to prevent and control malignant cells8.
Venetoclax is a selective inhibitor of a protein, named B-Cell lymphoma 2 (BCL-2 protein) that inhibits cell death (anti-apoptotic protein). Overexpression of the BCL-2 protein has been demonstrated in BCL-2 cells where it mediates tumour cell survival and has been associated with resistance to chemotherapeutics. Patients with the 17p deletion usually have poor outcomes with conventional chemo-immunotherapy9. Venetoclax is the first approved treatment that helps restore the process of apoptosis (cell death) by binding directly to the BCL-2 protein and preventing the inhibition of cell death1.
Where has Venclexta/Venclyxto (venetoclax) been approved?
Venclexta/Venclyxto (venetoclax) was approved by:
Food and Drug Administration (FDA), USA: April 11, 2016, for the treatment of patients with CLL or small lymphocytic lymphoma (SLL) with or without 17p deletion who have received at least one prior therapy1.
European Medical Agency (EMA), European Union, December 5, 2016 for the treatment of CLL in the presence of 17p deletion or mutation in adult patients who are unsuitable for or have failed a B-cell receptor pathway inhibitor and for the treatment of CLL in the absence of 17p deletion or TP53 mutation in adult patients who have failed both chemoimmunotherapy and a B-cell receptor pathway inhibitor2.
Therapeutic Goods Administration (TGA), Australia, January 5, 20179, in combination with rituximab, for the treatment of adult patients with CLL who have received at least one prior therapy. As monotherapy, it is indicated for the treatment of patients with relapsed or refractory CLL with 17p deletion or patients with relapsed or refractory CLL for whom there are no other suitable treatment options3.
Health Canada, Canada, September 2016, in combination with rituximab, for the treatment of patients with CLL who have received at least one prior therapy. As monotherapy it is indicated for the treatment of patients with CLL with 17p deletion who have received at least one prior therapy, or patients with CLL without the 17p deletion who have received at least one prior therapy and for whom there are no other available treatment options4.
