Dec 18 · Granted priority review in the US [2].

Oct 18 · Filed in US. The NDA filing is based on the results of 7 completed clinical studies in 5 bony and soft tissue surgical procedures that included over 1,000 patients who received HTX 011 [2].

Oct 19 · Oct 19: Positive topline results from multicentre PIIIb open-label single-arm, postoperative pain management study in 51 pts undergoing total knee arthroplasty (TKA) surgery. HTX-011 + scheduled postoperative oral acetaminophen and celecoxib. In this study, mean pain scores remained in the mild range through 72 hours post-surgery. Median consumption of opioids was 4-to-5 pills of oxycodone (22.5 morphine milligram equivalents) through 72 hours and 75% of pts were discharged without opioids. HTX-011 + oral analgesic regimen was well tolerated and there were no deaths, serious adverse events or premature discontinuations due to adverse events.[3]

Mar 18 · Top-line data from the two PIII EPOCH 1 and EPOCH 2 trials released. The results from the these trials will support the NDA [2].

Mar 18 · PIII EPOCH 1 study to evaluate the analgesic efficacy and safety of bupivacaine/meloxicam administered via local administration into the surgical site in subjects undergoing bunionectomy completes (NCT03295721; HTX011-301). The randomised, double-blind, saline placebo- and active-controlled trial enrolled 412 patients in the US [2].

Jan 18 · PIII EPOCH 2 trial designed to evaluate the efficacy and safety of bupivacaine/meloxicam, applied locally to the surgical site, for postoperative analgesia in patients undergoing unilateral open inguinal herniorrhaphy completes (HTX-011-302; NCT03237481). The primary endpoints were the difference in mean area under the curve (AUC) of pain intensity scores through 72 hours compared with placebo. The randomised, saline placebo and active controlled trial enrolled 418 patients in the US and Belgium [2].
