DSUVIATreatment for Pain
AcelRx Pharmaceuticals Receives Complete Response Letter from the FDA for DSUVIA NDA
REDWOOD CITY, Calif., Oct. 12, 2017 /PRNewswire/-- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX) (AcelRx), a specialty pharmaceutical company, today announced that it received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) regarding its New Drug Application (NDA) for DSUVIA™ (sufentanil sublingual tablet), 30 mcg.
The CRL states that the FDA determined it cannot approve the NDA in its present form and provides recommendations needed for resubmission. The two primary recommendations within the CRL are: first, while the safety database was suitable in number of patients, the collection of additional data was requested on at least 50 patients to assess the safety of DSUVIA dosed at the maximum amount described in the proposed labelling; second, to ensure proper administration of the tablet with the single-dose applicator, the FDA recommended certain changes to the Directions for Use to address use-related errors, including dropped tablets, to be validated through a human factors study.
"We believe the recommendations stated in the CRL are manageable and plan to fully cooperate with the FDA. We remain focused on the NDA resubmission and our mission to provide physicians and patients with precise and efficient non-invasive pain management options for moderate-to-severe acute pain within medically supervised settings," said Vincent J. Angotti, chief executive officer, AcelRx.
AcelRx will request a meeting with the FDA to discuss the topics covered in the CRL, and confirm plans to move towards resubmission of the DSUVIA NDA. AcelRx ended the third quarter with an estimated $67.9 million in cash and we will provide further financial updates on our third quarter earnings call.
About DSUVIA™ (sufentanil sublingual tablet), 30 mcg
DSUVIA™ (sufentanil sublingual tablet, SST, 30 microgram), known as ARX-04 outside the United States, is designed to reduce moderate-to-severe acute pain and dosing errors associated with IV administration via its non-invasive single-dose applicator (SDA) in medically supervised settings. Sufentanil is an opioid analgesic currently marketed for intravenous (IV) and epidural anesthesia and analgesia. However, its use has been limited due to its short duration of action when delivered intravenously. The sufentanil pharmacokinetic profile when delivered sublingually potentially avoids the high peak plasma levels and short duration of action observed with IV administration. In the EU, the European Medicines Agency (EMA) has notified the company that the ARX-04 Marketing Authorization Application (MAA) is under scientific review.

AcelRx Pharmaceuticals, Inc. is a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of moderate-to-severe acute pain. AcelRx's proprietary, non-invasive sublingual formulation technology delivers sufentanil with consistent pharmacokinetic profiles.The company is simultaneously developing ZALVISO®(sufentanil sublingual tablet system, SST system, 15 microgram) as an innovatively designed patient-controlled analgesia (PCA) system for reduction of moderate-to-severe pain in medically supervised settings. The company recently completed a Phase 3 clinical trial, IAP312, which included input from the FDA on the study protocol. This study was designed to evaluate the effectiveness of changes made to the functionality and usability of the ZALVISO device, to evaluate the incidence of inadvertent dosing, and to take into account comments from the FDA on the study protocol. AcelRx intends to resubmit the NDA for ZALVISO to the FDA by the end of the year. AcelRx has successfully received EU Marketing Approval for ZALVISO®in the EU. Grunenthal Group holds the rights for ZALVISO® in Europe, where a commercialization across multiple countries is underway.
