|PACIRA PHARMACEUTICALS, INC. filed this Form 10-K on 03/01/2017|
In January 2015, we announced two product candidates to our DepoFoam based pipeline: DepoTranexamic Acid, or DepoTXA, and DepoMeloxicam, or DepoMLX.
Tranexamic Acid, or TXA, is currently used off-label as a systemic injection or as a topical application, and is used to treat or prevent excessive blood loss during surgery by preventing the breakdown of a clot. The current formulation of tranexamic acid, however, has a short-lived effect consisting of only a few hours, while the risk of bleeding continues for two to three days after surgery. We believe DepoTXA, a long-acting local antifibrinolytic agent combining immediate and extended release TXA, could address the unmet, increasing need for rapid ambulation and discharge in the ambulatory surgery environment for joint surgery (primarily orthopedic surgery, including spine and trauma procedures and cardiothoracic surgery). Designed for single-dose local administration into the surgical site, DepoTXA could provide enhanced hemostabilization and improved safety and tolerability for patients over the systemic use of TXA by reducing bleeding, the need for blood transfusions, swelling, soft tissue hematomas and the need for post-operative drains, thereby increasing vigor in patients while decreasing overall costs to the hospital system.
DepoTXA is currently in Phase 2 clinical development.
Our preclinical product candidate, DepoMLX, is a long-acting non-steroidal anti-inflammatory drug, or NSAID, designed to treat moderate to severe acute postsurgical pain as part of a non-opioid multimodal regimen. A product designed for single-dose local administration such as DepoMLX could provide a longer duration of pain relief at a significantly lower concentration of systemic NSAIDs, which are known to cause dose-dependent gastrointestinal side effects. Meloxicam, which is currently available as an oral formulation, is a commonly used NSAID on the market today. We expect our customer audience for this drug to be similar to the target for EXPAREL infiltration.
We expect to submit an Investigational New Drug, or IND, application and subsequently initiate a Phase 1 clinical trial of DepoMLX in 2017.
Research and Development
In the years ended December 31, 2016, 2015 and 2014, we spent $45.7 million, $28.7 million and $18.7 million, respectively, on research and development activities. For additional information, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Research and Development Expenses.”
Sales and Marketing
We have built our marketing and sales organization to commercialize EXPAREL and our product candidates in the US. We intend to out-license commercialization rights for other territories. Our goal is to retain significant control over the development process and commercial execution for our product candidates, while participating in a meaningful way in the economics of all products that we bring to the market. The primary target audience for EXPAREL is healthcare practitioners who influence pain management decisions including surgeons, anesthesiologists, pharmacists and nurses.
Our field team, consisting of both sales representatives and scientific and medical affairs professionals, executes on a full range of activities for EXPAREL, including:
