In May 2012, the European Commission (EC) granted conditional marketing authorization for PIXUVRI as a monotherapy for the treatment of adult patients with multiply relapsed or refractory aggressive NHL. The benefit of PIXUVRI treatment has not been established in patients when used as fifth line or greater chemotherapy in patients who are refractory to last therapy. The Summary of Product Characteristics (SmPC) has the full prescribing information, including the safety and efficacy profile of PIXUVRI in the approved indication. The SmPC is available at www.pixuvri.eu. PIXUVRI does not have marketing approval in the United States.
NHL is the sixth most common cancer in the UK; in 2010, 12,180 people were diagnosed with the disease.
NHL is caused by the abnormal proliferation of lymphocytes, cells that are key to the functioning of the immune system. It usually originates in lymph nodes and spreads through the lymphatic system. NHL can be broadly classified into two main forms—aggressive and indolent NHL. Aggressive NHL is a rapidly growing form of the disease that moves into advanced stages much faster than indolent NHL, which progresses more slowly.
There are many subtypes of NHL, but aggressive B-cell NHL is the most common and accounts for about 55 percent of NHL cases.
After initial therapy for aggressive NHL with anthracycline-based combination therapy, one-third of patients typically develop progressive disease.
Approximately half of these patients are likely to be eligible for intensive second-line treatment and stem cell transplantation, although 50 percent are expected not to respond.
For those patients who fail to respond or relapse following second-line treatment, treatment options are limited, and usually palliative only.
About Conditional Marketing Authorization
Similar to accelerated approval regulations in the United States, conditional marketing authorizations are granted in the E.U. to medicinal products with a positive benefit/risk assessment that address unmet medical needs and whose availability would result in a significant public health benefit. A conditional marketing authorization is renewable annually. Under the provisions of the conditional marketing authorization for PIXUVRI, CTI will be required to complete a post-marketing study aimed at confirming the clinical benefit previously observed.
