Among those cases, there were 10 cases of hepatosplenic T-cell lymphoma, seven cases of non-Hodgkinâ€™s lymphoma, six cases of leukemia, and six cases of Hodgkinâ€™s lymphoma. The cancers were reported in children treated with various doses of the drugs and no single dose was associated with a higher cancer rate, the FDA said.
There were 32 cancer cases reported in the United States and 16 reports came from outside the U.S., according to the FDA.
TNF blockers are used to treat a variety of diseases and disorders, but they are most often used in children to treat inflammatory bowel disease, rheumatoid arthritis, and Crohnâ€™s disease. Besides Humira, Enbrel, and Remicade, other popular brand names of TNF blockers are Cimzia and Simponi.
FDA Investigates Cancer Link
Last year, the FDA launched an investigation into a link between the use of TNF blockers and cancer in children. The FDA recently announced that there had been 11 deaths among the 48 cancer cases. Those deaths were caused by T-cell lymphoma and sepsis after reaching remission of the lymphoma.
Last month, the FDA ordered the makers of TNF blocker drugs to include stronger warnings about the cancer risks on the productsâ€™ packaging. The FDA also required the drugs to update the prescribing information to include the risk of the chronic skin disease psoriasis associated with the use of the drugs.
