REDWOOD CITY, Calif., Oct. 1 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. today announced that it has completed an End-of-Phase 2 meeting with the US Food and Drug Administration (FDA) for ARX-02, a proprietary Sufentanil NanoTab™ Breakthrough Pain Management System for the treatment of cancer breakthrough pain in opioid-tolerant patients. FDA reviewed a package based on the previously announced positive Phase 2 clinical study results to date for ARX-02 and provided AcelRx with guidance on the Phase 3 program design and NDA requirements. Richard King, AcelRx CEO stated, "Given this guidance, we have clarity on the development path for ARX-02 in cancer breakthrough pain. In addition, FDA provided clarity on the development requirements to register ARX-02 for the broader indication of chronic breakthrough pain in opioid-tolerant patients, where we believe that ARX-02 can have an impact on the lives of a broader array of opioid-tolerant patients."
AcelRx is developing ARX-02, a novel sublingual Sufentanil NanoTab product candidate, as a new treatment option for patients with cancer breakthrough pain. Sufentanil is a strong opioid that is approximately 5-10 times more potent than fentanyl, yet has an 80-fold wider safety margin (therapeutic index), as determined in animal studies. The NanoTab is a very small tablet designed to allow rapid uptake of sufentanil following placement under the tongue, maximizing transmucosal drug uptake and limiting the proportion of swallowed drug. ARX-02 enables rapid onset of pain relief with a consistent, relatively short duration of action, closely matching the timing of a breakthrough pain episode.
