countries,” said

Vince Angotti

, Chief Executive Officer at AcelRx. “This collaboration provides a strategic fit for DZUVEO given Aguettant’s existing product portfolio. Having the ability to commercialize two product candidates in

the United States

Europe

aligns with our strategy of building a complementary product portfolio to DSUVIA while limiting the cost of development,” continued Angotti.

“DZUVEO complements our existing product portfolio and we’re delighted about this strategic opportunity to partner with AcelRx,” said Eric Rougemond, Chief Executive Officer at Laboratoire Aguettant. “Our worldwide presence in the acute care space makes us an ideal European partner for DZUVEO.  Partnering with AcelRx to commercialize two of our key acute care products in the U.S. further reinforces our mutual commitment to this strategic partnership.”

About DSUVIA (sufentanil sublingual tablet), 30 mcg


DSUVIA

^®

, known as DZUVEO

^®

in

Europe

, 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

for the management of acute moderate to severe pain in adults in medically monitored settings.
