Lenalidomide in addition to a chemotherapy combination known as R-CHOP is in clinical development for newly diagnosed, previously untreated adult patients with diffuse large B-cell lymphoma (DLBCL) of the subtype known as activated B-cells (ABC) type. DLBCL is a cancer affecting a type of white blood cells called lymphocytes or B-cells. It is the most common form of non-Hodgkin lymphoma among adults. DLBCL is an aggressive cancer and although it can be cured in more than half of people affected, it remains a serious and life threatening disease. Treatment does not work as well for patients with the ABC type compared to patients with other DLBCL types who receive standard treatment.
Lenalidomide is a derivative of thalidomide and in DLBCL works by blocking the development of tumour cells, preventing the growth of blood vessels within tumours and stimulating some of the specialised cells of the immune system to attack the cancerous cells. It is administered orally in addition to current standard of therapy R-CHOP. The addition of lenalidomide to R-CHOP for this population subgroup may improve effectiveness and prognosis.
Nivolumab works by improving the activity of white blood cells thereby increasing the ability of the immune system to kill cancer cells. Cabozantinib works to stop signals that cancer cells use to divide and grow. It is thought that when used in combination, both drugs may be more effective than each drug on its own. If licenced, nivolumab in combination with cabozantinib may improve long-term outcomes in mRCC patients who currently have limited treatment options.
