AcelRx Pharmaceuticals presented at the ANESTHESIOLOGY 2022 meeting about the potential of DSUVIA® for battlefield analgesia. The abstract emphasizes the advantages of the sufentanil sublingual tablet (SST) for rapid pain relief, citing its benefits over traditional opioid options like morphine and fentanyl. Aimed at the Department of Defense, the SST is noted for its quick onset, minimal side effects, and low risk of addiction, marking a significant evolution in military pain management protocols. CEO Vince Angotti reiterated the importance of DSUVIA as a safer alternative for soldiers in acute trauma situations.

Positive
  • DSUVIA offers rapid analgesia in battlefield settings, with effects within 15 minutes.
  • Sufentanil sublingual tablet presents lower addiction risks compared to traditional opioids.
  • The Department of Defense is considering the SST to improve pain management for soldiers.
Negative
  • None.

Presentation concludes that future battlefield medicine efforts should focus on newer analgesics like DSUVIA® across military settings and establish protocols for their implementation in the trauma setting

HAYWARD, Calif., Oct. 25, 2022 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), (AcelRx), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today announced that an abstract entitled, "Evolution Of Opioid Analgesia On The Battlefield For Moderate-to-Severe Acute Pain" (abstract # A4123) was presented by lead author, Sharon Kim, M.S., at the ANESTHESIOLOGY® 2022 annual meeting, held October 21-25, 2022 in New Orleans, LA. The authors of the abstract, from the nation's federal health sciences university, recommend the adoption of a sufentanil sublingual tablet (SST), 30 mcg (or DSUVIA®) by the Department of Defense (DoD) to improve pain management in the battlefield setting.

In the abstract, the authors state, "In 2018, the DoD introduced its newest synthetic opioid, sublingual sufentanil tablet (SST), intended to be a more effective analgesic option" noting that SST is the first oral mucosal opioid microtablet (3mm diameter) designed to provide analgesia within as early as 15 minutes from administration, maintain therapeutically effective analgesic levels for up to 3 hours, and reduce the risk of dosing errors through its innovative applicator design. The authors then highlight that "the sublingual tablet  has a bioadhesive surface to adhere to the oral mucosa, minimizing salivary response and swallowing" and state that the "sublingual administration enables a longer drug plasma half-life allowing for more consistent plasma concentrations over time and eliminating the need for repeated dosing. Since sublingual sufentanil has a high therapeutic index with no active metabolites, drug administration incurs minimal side-effects (e.g., nausea, dizziness, headache) and is not associated with cognitive impairment." The therapeutic index of a drug is the margin of safety that exists between the dose of a drug that produces the desired effect and the dose that produces unwanted and possibly dangerous side effects.

The authors continued by noting that, in contrast to morphine and fentanyl, sublingual sufentanil has minimal euphoric effects that commonly drive opioid addiction. In particular, the authors identified the combination of the tablet formulation and sublingual delivery of the SST provides a low peak drug plasma concentration, thus avoiding the initial high peak opioid concentrations responsible for adverse events.  The authors acknowledged that "to date, no transmucosal opioid products are approved for the treatment of moderate-to-severe acute pain in patients who are opioid-naive, demonstrating the medical benefits of SSTs."

The authors concluded, "Overall, the DoD recognizes the therapeutic benefits of potent opioids in acute trauma settings and has aimed to improve battlefield opioid usage, which evolved from IV morphine administration to [fentanyl] lollipops to finally SSTs. Future work should aim to improve opioid products for the battlefield, discover non-opioid analgesic options, and establish optimal drug administration protocol in trauma settings."

"DSUVIA offers an alternative for pain relief with many potential advantages for use on the battlefield including ease of dosing, rapid onset and a high therapeutic index," stated Vince Angotti, Chief Executive Officer of AcelRx. As the military acknowledges, DSUVIA is the only transmucosal opioid that is approved for patients who are opioid-naive, such as our soldiers in the military. The Department of Defense, or DoD, has repeatedly recognized the need for a product like DSUVIA, a novel sublingual tablet which they believe should provide a safer alternative to our soldiers for pain relief compared to existing options. We continue to work with the critical decision-makers at the Department of Defense to make this important drug available to our men and women serving in our U.S. military."

E-Abstracts will be presented virtually and made available to registrants throughout the entire meeting from Saturday, October 22 (7:00 a.m. US Central Time) through Tuesday, October 25, 2022 (3:00 p.m. U.S. Central Time). The abstracts will remain available and open to meeting attendees for three months after the meeting.

History of Pain Management in the Military Setting
Morphine has been the primary analgesic on the battlefield since the 19th century and was originally developed as a less addictive alternative to opium. However, the drug has a narrow therapeutic index (TI), and morphine abuse and overdose continued into World War II and the 20th century. Even after the inception of morphine over a century ago, the U.S. military has used intramuscular (IM) morphine for battlefield analgesia, although disadvantages include inconsistent absorption, delayed onset, and compromised pain relief. In 1996, the Department of Defense (DoD) developed the Tactical Combat Casualty Care (TCCC) guidelines for trauma life support and pain management in prehospital combat settings. The 1996 TCCC guidelines stated that IV morphine is preferable to IM morphine due to the more rapid onset of action, providing faster pain relief and decreasing the risk for overdose. The DoD then shifted focus to introducing opioids that can be administered through the oral or nasal mucosa when IV access is unfeasible. In 2004, the DoD added oral transmucosal fentanyl citrate (OTFC) to the TCCC guidelines. OTFC was primarily used to treat intense cancer pain but was recommended for off-label use on the battlefield. OTFC is packaged as a lozenge on a handle (like a lollipop) and quickly absorbed through the oral mucosa. Some fentanyl that is swallowed is absorbed through the gastrointestinal tract. Disadvantages of OTFC include a high incidence of side-effects (nausea, vomiting, respiratory depression, sedation) and risk for opioid addiction and misuse.1

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. DZUVEO has been approved by the European Medicines Agency and AcelRx's European commercialization partner, Aguettant, will market the drug in Europe.
