Healthcare Industry News: Zalviso
News Release - January 8, 2016
AcelRx Completes Protocol Review with FDA and Plans to Initiate Phase 3 Open-Label Study (IAP312) for Zalviso(TM) in 1Q 2016REDWOOD CITY, Calif., Jan. 8, 2016 -- (Healthcare Sales & Marketing Network) -- AcelRx Pharmaceuticals, Inc. (ACRX), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute pain, today reported that the Company has received comments from the Division of Anesthesia, Analgesia, and Addiction Products (Division) of the U.S. Food and Drug Administration (FDA) on the Company's proposed protocol for a Phase 3 clinical study (IAP312) designed to assess the overall performance of Zalviso™(sufentanil sublingual tablet system). In response to the comments, the protocol has been amended and AcelRx plans to initiate the study in the first quarter of 2016. The IAP312 study will include approximately 310 post-operative patients and collect information requested by the Division to supplement the three positive Phase 3 trials already completed. Zalviso is being developed for the management of moderate-to-severe acute pain in adult patients in the hospital setting.
"Even though we've performed extensive bench and human factors testing to demonstrate the reliability and usability of Zalviso since our successful Phase 3 trials, we acknowledge the Division's desire to see additional Zalviso use by patients in a clinical setting," commented Howie Rosen, interim chief executive officer of AcelRx. "We are pleased that we have a path forward in the U.S. that should lead to resubmission of the NDA."
The planned open-label Phase 3 study will enroll adult postoperative patients who will self-administer 15 mcg sublingual sufentanil using Zalviso for 24-to-72 hours. Patients will self-administer study drug as often as once every 20 minutes to manage their moderate-to-severe acute pain. The study will measure the rate of device errors, including the failure to dispense medication as well as the incidence of misplaced or dropped tablets. Efficacy pain measurements and safety data will also be collected in the study.
The NDA resubmission will include, in addition to the results of bench testing and human factors studies conducted with the modified Zalviso design, the results from the IAP312 study. Prior Phase 3 trials include two Phase 3 placebo-controlled studies (IAP310 and IAP311) in which Zalviso demonstrated superiority over placebo in the management of moderate-to-severe acute post-operative pain, as measured by time-weighted SPID48, the primary endpoint. In IAP309, a Phase 3 active-controlled study, Zalviso was statistically significantly superior (p=0.007) in patient global assessment (PGA) of method of pain control in comparison to intravenous (IV) PCA morphine. The most common adverse events experienced by patients using Zalviso were nausea, pyrexia (fever) and vomiting.
About AcelRx Pharmaceuticals, Inc.
AcelRx Pharmaceuticals, Inc. is a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of acute pain. The company's late-stage pipeline includes ARX-04 (sufentanil sublingual tablet, 30 mcg) designed for the treatment of moderate-to-severe acute pain in a medically supervised setting; and Zalviso designed for the management of moderate-to-severe acute pain in adult patients in the hospital setting.
ARX-04 delivers 30 mcg sufentanil, a high therapeutic index opioid, sublingually through a disposable, pre-filled, single-dose applicator. AcelRx has reported positive results from the pivotal Phase 3 SAP301 ambulatory surgery study, and has advanced ARX-04 into a study (SAP302) in emergency room patients. In addition, AcelRx intends to initiate SAP303 in the first quarter of 2016, with a focus on enrolling patients greater than 40 years of age, allowing for administration of ARX-04 for up to 12 hours. Zalviso delivers 15 mcg sufentanil sublingually through a non-invasive delivery route via a pre-programmed, patient-controlled analgesia device. In response to the New Drug Application (NDA) AcelRx submitted to the U.S. Food and Drug Administration (FDA) seeking approval for Zalviso, AcelRx received a Complete Response Letter (CRL) on July 25, 2014. The FDA has requested an additional clinical study (IAP312), which AcelRx is planning to initiate in the first quarter of 2016, to support resubmission of the NDA.
