GlaxoSmithKline (GSK) won FDA approval of Tykerb for advanced breast cancer. Because the indication is tightly limited, the effect on GSK will not be great until Tykerb becomes used for more types of cancer. Initially, Tykerb, which be administered along with Herceptin from Genentech (DNA), is to be given to patients with HER2 positive breast cancer as a second-line treatment. Tykerb inhibits both the HER2 and EGFR proteins. It is thought to be especially effective in preventing brain metastases. Tykerb remains in trials as a first-line breast cancer drug and for other types of cancer as well.

Adolor (ADLR) announced that GlaxoSmithKline (GSK), its partner on Entereg, is planning an additional Phase III trial of Entereg to prove safety. Entereg is a treatment for opiate-induced constipation. The FDA gave Entereg an approvable letter, but asked for more data about cardiovascular side-effects. Because GSK is willing to undertake the trial, analysts opined the company must surmise the drug is safe.

Cell Therapeutics (CTIC) has filed a Special Protocol Assessment request with the FDA for a Phase III trial of pixantrone for non-Hodgkin’s lymphoma.
