AcelRx is currently focused on the development of products for the treatment of moderate-to-severe acute pain based on the company’s proprietary sublingual formulation technology. For more information, please select a product below.
DSUVIA/ARX-04 (sufentanil sublingual tablet, 30 mcg)
DSUVIA/ARX-04 is designed to provide a non-invasive treatment option for patients with moderate-to-severe acute pain, in multiple medically supervised settings ranging from the battlefield, civilian emergency departments, ambulatory surgery centers, and hospitals.
The DSUVIA/ARX-04 Phase 3 clinical program, which concluded in September 2016, assessed the investigational product in the treatment of moderate-to-severe acute pain in three Phase 3 trials:
- SAP301, a multi-center, double-blind, placebo-controlled study in patients who had undergone ambulatory abdominal surgery;
- SAP302, a multi-center, open-label study in adults who presented to an emergency room with trauma or injury; and
- SAP303, a multi-center, open-label study in patients who had undergone short-stay in-hospital surgery.
In each of these Phase 3 clinical studies, DSUVIA/ARX-04 has shown improvements in pain intensity as early as 15-to-30 minutes after the start of dosing, with most common adverse events including nausea, headache, dizziness, and vomiting. Efficacy and safety measures have thus far appeared consistent among age groups and comorbidities, such as hepatic impairment. In addition, SAP302 provided evidence that DSUVIA/ARX-04 is not been associated with drug-induced cognitive impairment.
Based on these clinical results, a New Drug Application (NDA) and a Marketing Authorization Application (MAA) were filed with the FDA in December and the European Medicines Agency (EMA) in March 2017, respectively.”
Zalviso® (sufentanil sublingual tablet system)
Currently, patients experiencing moderate-to-severe acute pain in the hospital may have intravenous patient controlled analgesia (IV PCA), as an option to treat their pain, typically utilizing morphine or hydromorphone.1 However, the use of IV PCA has been associated with deficiencies that can negatively impact patient safety and recovery. These include: a) side effects from morphine or hydromorphone and their active metabolites;2 b) medication delivery errors typically related to misprogramming IV PCA pumps; and c) complications associated with IV delivery such as infection risk and decreased mobility potentially related to the invasive nature of IV delivery.3
Zalviso is designed to address these problems by delivering 15 mcg sufentanil, a high therapeutic index opioid, formulated in a proprietary non-invasive sublingual dosage form via a novel hand-held, pre-programmed, patient-controlled analgesia system.
Zalviso has completed three Phase 3 clinical trials: two placebo-controlled efficacy and safety trials and one open-label active comparator trial, in which Zalviso was compared to IV PCA morphine. Each of the three Phase 3 trials successfully achieved its primary endpoint. Based on FDA feedback, AcelRx has initiated a fourth study (IAP312) in a diverse post-surgical population to further evaluate the overall performance of the Zalviso System.
