/PRNewswire/ — AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), (AcelRx), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in healthcare institutions, today announced an investigator-initiated study with University Hospitals (UH) Cleveland Medical Center that will evaluate the postoperative use of DSUVIA in a prospective cohort of patients undergoing cardiac surgery with cardiopulmonary bypass following a specialized enhanced recovery protocol. Dr.

Daniel Asher

, cardiac anesthesiologist and Medical Director of the Mather Postanesthesia Care Unit at UH Cleveland Medical Center, will serve as the principal investigator. Key outcomes to be measured include time on mechanical ventilation following completion of the surgical procedure, both intensive care as well as hospital length of stay and total dose of opioids administered from surgery to discharge. These outcomes will be compared to historical controls utilizing current institutional standard of care techniques.

“We look forward to evaluating DSUVIA as part of our cardiac surgery enhanced recovery program which is aiming to better prepare our enrolled subjects for the stress of heart surgery by using contemporary preoperative adjuncts, educational tools, intraoperative monitoring techniques and, importantly, actively reducing the exposure of these patients to IV opioids and their side effects,” states the study’s co-investigator Dr.

Edwin Avery

, Vice Chair of Clinical Operations and Professor of Anesthesiology at UH Cleveland Medical Center, and Professor, Anesthesiology and Perioperative Medicine,

Case Western Reserve University

School of Medicine. “We believe the higher therapeutic index of sufentanil and the lower peak plasma concentrations delivered via the sublingual route compared to bolus IV administration will allow DSUVIA to help us achieve our goal,” continues Dr. Avery.

“This investigator-initiated study at UH Cleveland presents another opportunity to assess the benefits of DSUVIA compared to IV opioids,” said Dr. Pamela Palmer, Co-Founder and Chief Medical Officer at AcelRx Pharmaceuticals. “The physicians at UH Cleveland Medical Center have chosen DSUVIA for evaluation in their enhanced recovery cardiac bypass program to determine if it provides effective pain relief while minimizing side effects during their postoperative recovery prior to discharge. This cardiac surgery study together with ongoing investigator-initiated trials of DSUVIA for orthopedic and spine surgeries at other top academic institutions allows DSUVIA to be assessed across a broad range of surgical subspecialties as an alternative to IV opioids.”

About DSUVIA (sufentanil sublingual tablet), 30 mcg


DSUVIA

^®

, known as DZUVEO

^®

in Europe, approved by the FDA in November 2018, is indicated for use in adults in certified medically supervised healthcare settings, such as hospitals, surgical centers, and emergency departments, for the management of acute pain severe enough to require an opioid analgesic, and for which alternative treatments are inadequate. DSUVIA was designed to provide rapid analgesia via a non-invasive route and to eliminate dosing errors associated with intravenous (IV) administration. DSUVIA is a single-strength solid dosage form administered sublingually via a single-dose applicator (SDA) by healthcare professionals. Sufentanil is an opioid analgesic previously only marketed for IV and epidural anesthesia and analgesia.

The sufentanil pharmacokinetic profile when delivered sublingually avoids the high peak plasma levels and short duration of action observed with IV administration. The European Commission approved DZUVEO for marketing in Europe in June 2018 and the Company is currently in discussions with potential European marketing partners.
