Before researchers can conduct clinical drug research in the United States, they must file an Investigational New Drug (IND) application with the FDA. Entelev, which is the original name of the mixture, was assigned an IND number (IND #20258) by the FDA in 1982.[4] The IND currently remains inactive because information about the product's composition and studies showing its therapeutic effectiveness in animals have not been provided to the FDA. Reviewed in [1] In 1989, the FDA was granted a permanent injunction against both principal manufacturers of Cancell/Cantron/Protocel prohibiting them or their agents from distributing the mixture, which was judged an unapproved new drug.

Cancell/Cantron/Protocel has been administered orally, rectally, and topically. Reviewed in [1] Topical skin application is accomplished by dampening a cotton pad with the liquid and taping the moistened pad to the wrist or the ball of the foot after first treating the area with dimethyl sulfoxide. Reviewed in [1] Cancer patients have also been advised to take bromelain, which is a digestive aid, and to avoid high intakes of vitamins C and E while undergoing treatment with Cancell/Cantron/Protocel.
