Thank you, Dr. Palmer. Hello, all. I'm Dr. Christian D. Tvetenstrandand and I'm excited to tell you about our experience with DSUVIA at our hospital. Of note, I'm not being compensated for my time to speak with you today. However previously I have been compensated for attending an advisory board meeting with AcelRx. I was initially interested in trialling DSUVIA in my surgical patients after learning of the pharmacokinetics of the drug. I often operate on obese patients, elderly patients and patients with multiple comorbidities, all of whom are at higher risk for side effects and complications post-operatively. While we all utilize multimodal analgesia regimens, enhancer [ph] a patient's pain relief and outcomes, we go after major surgery this regimen is going to include opioids. To optimize the opioid analgesia for these at-risk patients, I was especially interested in DSUVIA for its low and steady plasma concentration and extended duration of action. When we use IV opioids, especially fentanyl, we are finding that we have to continually re-dose the patient in the PACU do the short duration of action. The rapid highs and lows of the plasma concentrations following each IV fentanyl injection is not ideal for these patients as they can quickly become confused and over sedated and then the drug levels rapidly fall off and then we have breakthrough pain. Also important my initial decision to utilize DSUVIA in these higher risk patients was the AcelRx clinical trial data which showed no cognitive impairment using the Six-item Screener, a validated research tool and the fact that DSUVIA has no active metabolite very important. Renal impairment quite common after surgery in elderly patients with comorbidities having significantly increase the level of active metabolites in the blood with opioids such as morphine or Dilaudid. These metabolites can quickly build up to levels that can cause central nervous system effects. As mentioned since February I have dosed over 100 patients with DZUVEO [ph] From my surgical patients I dose a single DZUVEO preoperatively approximately 20 minutes prior to bringing them back to the operating room. We have initially focused our use of DZUVEO in outpatient surgeries. This is critically important to maintain clear headedness in these patients so we can facilitate a rapid discharge to home. Patients with post-op confusion or side effects such as nausea and vomiting can significantly delay time to discharge and can seriously impact our surgical patient flow. Most notably the elderly can have severe post-operative delirium with many medications utilized in a perioperative setting including opioids. The first day I dosed DSUVIA in my hospital, I trialled it in four patients undergoing abdominal surgery. These cases typically take an hour or so depending on their complexity. The nurses in the PACU, as well as the anesthesiologists were hesitant to believe that a single dose of DSUVIA would be all that the patient would need for opioid analgesia. To say the results have been quite shocking to some, it's not an overstate. Minim to no other IV opioids are required during the operative case. Normally they would have been delivering multiple doses of fentanyl during and immediately after the case. In the PACU patients are waking up alert oriented and comfortable. Only a few patients have required a second dose of DSUVIA even after lengthy surgery. So the analgesic last an extended period of time as you would expect from a review of the pharmacokinetic. Our overall use of opioids has decreased in these patients, and has freed up the nurses in the PACU to focus more on clinical care of the patient and moving them towards discharge instead of having to administer more IV opioids which we find further extends their stay. We have been collecting time to discharge data on all our DSUVIA patients and there is a dramatic reduction in the time needed for the patients to be ready for discharge compared to our historical controls. We have not seen respiratory depression and we have seen very minimal nausea and no vomiting. It has really been a game changer for us. We are currently in the process of fully analyzing the data for publication, as I believe that other surgeons who’d be quite interested in learning about a new way to treat acute moderate to severe pain in the patient - in the perioperative setting while potentially minimizing side effects, reducing overall opioid dosing and decreasing discharge time. My second area of interest for DSUVIA was for the use in the elderly patients. For years I have observed the elderly with multiple morbidity can decline quite rapidly after acute traumatic event. These patients are initially admitted typically to the emergency department and many times we see them in the winter after slips on the sidewalk with a myriad of hip fractures, hip femur, arm fractures and other types of injuries. In some cases these patients are never discharged back to home and are relegated to a skilled nursing facility. Treatment of severe pain can often require repeated doses of opioids. And as mentioned before most commonly used opioids have active metabolites that can build up over time, especially when renal function is diminished, which is a common finding in the elderly. This results in mental clouding, confusion delirium, which can impair mobility often leading to extended rehabilitation stays. I felt that if we could utilize DSUVIA early on in the treatment of these patients we could avoid this downward spiral. My first night using DSUVIA in the emergency department of a hospital was an eye opener for me. I distinctly remember the first two patients. One was a 93 year old gentleman who had broken his hip and had been dosed with DSUVIA. After I went back to check on him, he was comfortable, he was awake, reading the newspaper and doing the crossword puzzle. That is not something you see every day. The second patient an elderly woman, she too had fallen and broken her hip and she was initially dosed with IV Dilaudid which is a common treatment. The patient was quite confused after the dosing and disoriented and her family was quite concerned. I left the Dilaudid where off for a few hours and then I dosed DSUVIA and lo and behold her pain was quite controlled and she was lucid and her family was quite relieved. These are just two examples of what I've now observed, time and time again with the elderly trauma patients. Overall, not only am I impressed with the efficacy and safety of DSUVIA, but I feel that the DSUVIA has simplified the treatment of acute moderate to severe pain in my surgical and acute trauma patients. Our nurses and anesthesiologists have also recognized the difference, doesn't matter whether patient has an IV or not, whether they're old or young [indiscernible] frail of men renal impairment or not is always the same dose under the tongue that being 30 microgram. While we can redose after an hour, it has rarely been necessary and given all the benefits we have observed the product more than pays for itself. I'm looking forward to expanding our use of DSUVIA in our inpatient, surgical population at the Wilson Medical Center, as well expanding our use in the emergency department. I hope to have DSUVIA added to the formulary at other hospitals where I operate. I am very excited to publish our patient data as it is important to share our experience and knowledge of DSUVIA to benefit other patients, health care providers and hospital systems. Thank you for your kind attention.
