Wednesday, 07 March 2012 06:21 Pharmaceuticals, Inc., a specialty pharmaceutical company, has announced the results from a pre-planned interim analysis of the phase II b trial of SCV-07 in patients with oral mucositis (OM) indicate that the trial would not meet the pre-specified efficacy endpoints. After conferring with the study's independent Data Monitoring Committee (DMC), the company has decided to discontinue development of SCV-07 in this indication.

SciClone is notifying the FDA and study investigators of the trial's discontinuation. No additional patients will be enrolled in the trial. Dosing of subjects currently enrolled in the trial will be discontinued, but subjects will be followed per protocol for a full year.

“Oral mucositis remains a debilitating condition for cancer patients who are in need of effective therapeutic options. We express our sincere appreciation to the investigators and patients who have participated in the phase II b trial,” said Friedhelm Blobel, PhD, president and CEO of SciClone. “While we certainly would have preferred to see a positive outcome from the SCV-07 phase II b trial interim analysis, as a practical matter, we now have the opportunity to complete our transition to a China-focused specialty pharmaceutical company. This will enable us to further curtail our US development expenses and focus resources on continuing to grow our commercial business in China, expand sales of our broad portfolio of marketed products and build our track record of impressive growth in revenue, profitability and earnings per share.”

Following the originally planned completion of the phase II b trial in mid-2012, SciClone had anticipated a significant decrease in development expenses beginning later this year. SciClone now anticipates that decreases in clinical activities and expenses related to the trial will begin earlier this year, and will have a positive impact on the company's full-year 2012 profitability and earnings.

The interim analysis included data on 85 subjects. The DMC had no safety concerns, but recommended discontinuing enrolling subjects into the trial as all three dosage arms indicated no efficacy of the drug relative to the primary or secondary OM endpoints.

SCV-07 (gamma-D-glutamyl-L-tryptophan) is a small molecule that appears to stimulate the immune system through inhibition of STAT3 signaling and the resulting effects on T-helper 1 cells. SCV-07 has been shown to be efficacious in animal models of immune-sensitive diseases, including prevention of oral mucositis, treatment of cancer and viral infections, and enhancement of response to vaccines.

Initiated in January 2011, the phase II b trial of SCV-07 is a multi-centre, randomized, double blind placebo-controlled study examining three doses of SCV-07, including two higher doses than those used in the phase II a study, to assess the drug's impact on modifying the course of oral mucositis in patients with head and neck cancer. The primary endpoint is the reduction in the proportion of patients with clinically assessed ulcerative OM, defined as WHO grade greater than or equal to 2 at the time they have received a cumulative radiation dose of 45 Gy.

SciClone Pharmaceuticals is a revenue-generating, profitable, specialty pharmaceutical company with a substantial commercial business in China and a product portfolio of therapies for oncology, infectious diseases and cardiovascular, urological, respiratory, and central nervous system disorders.
