Healthcare Industry News: Enzastaurin
News Release - December 21, 2006
Data Monitoring Committee Recommends Closing Enrollment in Recurrent Glioblastoma StudyOther Enzastaurin Trials Unaffected
INDIANAPOLIS, Dec. 21 (HSMN NewsFeed) -- After reviewing data gathered to date, as part of a planned interim analysis, an External Data Monitoring Committee (DMC) has recommended that the STEERING trial (Study Evaluating Enzastaurin in Recurrent Glioblastoma) be closed for enrollment. The global Phase III study was evaluating Enzastaurin for the treatment of an aggressive and recurrent form of brain cancer.
Results of this planned interim analysis suggested that Enzastaurin would not meet the primary endpoint of improvement in progression-free survival over an existing chemotherapy in this particular study. Lilly accepted the DMC recommendation and immediately contacted all STEERING study investigators to inform them of the decision and to provide them all available information to manage patients.
"We are disappointed for patients suffering from recurrent glioblastoma, but we remain confident and committed to the development of Enzastaurin," said Richard Gaynor, M.D., vice president, cancer research and global oncology platform leader for Eli Lilly and Company. "Recurrent glioblastoma is a rare and difficult to treat tumor and patients and their families are seeking innovative treatment options. Given the independently validated response rate of 22-percent in a phase II trial, we plan to thoroughly review the data from this interim analysis and apply the insights learned to the glioblastoma program. Based on preclinical and clinical evidence, the company also remains fully committed to the continued development of Enzastaurin."
Enzastaurin is being evaluated in a Phase III trial (currently enrolling patients) as a maintenance therapy for the treatment of non-Hodgkin's lymphoma as well as being evaluated in several phase II studies across a variety of more common tumor types including: breast, colon, lung, ovarian and prostate cancers. These additional trials are unaffected by the DMC recommendation.
Enzastaurin is a potent multi-kinase inhibitor which targets selectively the PKCbeta and PI3/AKTsignaling pathways. By blocking these key pathways frequently over-expressed in a wide variety of cancers, Enzastaurin suppresses tumor cell proliferation, induces tumor cell death and inhibits tumor-induced angiogenesis. As further evidence to the rare and unmet medical need of recurrent glioblastoma, Enzastaurin was granted orphan drug designation by the European Agency for the Evaluation of Medicinal Products (EMEA) and by the U.S. Food and Drug Administration's Office of Orphan Products Development for the treatment of glioblastoma.
Background on STEERING Trial
The STEERING trial (Study Evaluating Enzastaurin in Recurrent Glioblastoma) is a randomized, open label registration study in recurrent glioblastoma multiforme (GBM) comparing the efficacy and safety of Enzastaurin, taken orally, versus CeeNUŽ (lomustine[CCNU]), a chemotherapy used to treat this disease. The primary endpoint is improvement in progression-free survival.
Glioblastoma is the most aggressive and malignant form of glioma, a type of primary brain cancer. In the early stages, glioblastoma tumors often grow quickly and without symptoms, becoming quite large before signs of altered brain function arise. Surgery is generally the first line of treatment, followed by radiation and/or chemotherapy. Although primary treatment is often successful in temporarily stopping the progression of the tumor, glioblastomas almost always recur and survival rates remain low.
Data Monitoring Committee
A Data Monitoring Committee (DMC) is an independent body consisting of physicians and statisticians. Their responsibility is to review interim analysis data from clinical trials and make a decision on whether the trial is still set up correctly or needs any modifications.
