The initial product launched proved to be the largest "biotech launch" in the history of the pharmaceutical industry, achieving first full year sales exceeding $US335M. Agourons patent on the drug expired in 2014. On the 6 June 2007, both the Medicines and Healthcare products Regulatory Agency and the European Medicines Agency put out an alert requesting the recall of any of the drug in circulation, because some batches may have been contaminated with potentially cancer-causing chemicals. Research
Since 2009, nelfinavir has been under investigation for potential use as an anti-cancer agent. When applied to cancer cells in culture (in vitro), it can inhibit the growth of a variety of cancer types and can trigger cell death (apoptosis). When Nelfinavir was given to laboratory mice with tumors of the prostate or of the brain, it could suppress tumor growth in these animals. At the cellular level, nelfinavir exerts multiple effects to inhibit cancer growth; the two main ones appear to be inhibition of the Akt/PKB signaling pathway and activation of endoplasmic reticulum stress with subsequent unfolded protein response.In the United States, about three dozen clinical trials are being conducted (or have been completed) in order to determine whether nelfinavir is effective as a cancer therapeutic agent in humans. In some of these trials, nelfinavir is used alone in monotherapy fashion, whereas in others it is combined with other modes of cancer therapy, such as well-established chemotherapeutic agents or radiation therapy.
Diflorasone diacetate is a topical steroid that comes in the form of a cream. It is manufactured by E. Fougera & Co. and is used as an anti-inflammatory and anti-itching agent, like other topical corticosteroids. It is prescribed for psoriasis and atopic dermatitis, among other conditions. With respect to potency, it is regarded as a Class I corticosteroid [of classes I – VII] in the United States.No long-term animal studies have been done to determine whether diflorasone diacetate could have carcinogenic properties.Little data is available regarding whether diflorasone diacetate would be present in great enough quantities to cause harm to an infant.
