CUPERTINO, Calif., May 11 /PRNewswire/ —
DURECT Corporation (Nasdaq: DRRX) announced today that the company has
completed the clinical portion of its Phase II clinical trial for the
company’s lead product, DUROS sufentanil. The last patient visit was completed
and data analysis and report writing are underway. Over 50 patients at
9 clinical centers completed the clinical portion of the study more than
3 months ahead of schedule. DUROS sufentanil is designed to deliver sufentanil
on a continuous basis for 3 months for the treatment of chronic pain.
Sufentanil is an FDA approved opioid that is currently used in hospitals as an
anesthetic. Chronic pain is a significant problem associated with chronic
diseases, including cancer and various neurological and skeletal disorders.
DUROS sufentanil is intended for patients whose chronic pain is stable, opioid
responsive and results from a variety of malignant and non-malignant causes.
Annual sales of opioids for the treatment of chronic pain are in excess of
$1 billion.
This Phase II trial was designed to determine the dose conversion from
other approved opioid medications to DUROS sufentanil. DURECT utilized an
advisory panel of leading clinical physicians and experts in the field of
chronic pain to develop the protocol for the Phase II trial. The trial
evaluated the safety and efficacy of continuous dose of sufentanil via a
subcutaneously implanted DUROS sufentanil system in stable opioid responsive
chronic pain patients. The information on relative potency and conversion
charts collected in this study will be used in Phase III trials designed to
demonstrate the safety and efficacy of the DUROS sufentanil product.
“We are very pleased at the progress that we have made with our Phase II
trial for DUROS sufentanil. The accelerated pace exceeds our expectations,”
said James E. Brown, President and CEO of DURECT. “We believe that this
reflects the potential benefits of this product to both patients and
physicians. We believe DUROS sufentanil has the potential to be a more
convenient, patient-friendly product that may provide an alternative to
current therapies for the long term treatment of stable and opioid responsive
chronic pain.”
“We believe that the rapid patient enrollment and completion of this Phase
II trial is due to the tremendous enthusiasm of our investigators for this
product, which we expect to carry forward to our Phase III trials,” said
Dennis Fisher, MD, Vice President of Medical Affairs and Medical Director of
DURECT.
