Ovarian cancer is a common type of cancer arising from different types of ovarian tissue in the female reproductive system. It is the sixth most common cancer in women in the UK. The ovaries are a pair of small organs located in the pelvis and are part of the female reproductive system. Usually women who have been through menopause are more likely to be affected by ovarian cancer. Most cases are caused by gene changes that develop during a woman’s life and are not inherited. Treatment of ovarian cancer involves surgery and/or chemotherapy depending on the stage at diagnosis. Most patients with ovarian cancer are diagnosed at an advanced stage and will require chemotherapy. However, most women ultimately relapse and/or become resistant (refractory) to common first-line chemotherapy treatment. Thus, there is a common need in this cancer to consider the use of second-line treatment.
Avelumab is in development for the second-line treatment of ovarian cancer when used either alone or in addition to the chemotherapy drug, Pegylated Liposomal Doxorubicin (PLD). Avelumab acts by preventing cancer cells from switching off T cells (cells of the immune system), which increases the ability of the T cells to kill the cancer cells. It is to be administered as an intravenous infusion. If licensed, avelumab may offer a second-line treatment option for patients with ovarian cancer, whose disease has relapsed or has become refractory after the first treatment.
Pembrolizumab is a medicinal product that is being investigated as treatment for patients with relapsed or refractory classical Hodgkin lymphoma (cHL). Hodgkin lymphoma is a type
of cancer of the lymphatic system and it is the most common type. The condition is called relapsed or refractory when it recurs after a period of improvement or when it does not
respond to treatment. The most common symptom of Hodgkin lymphoma is a swelling in the neck, armpit or groin.
