Editorial on Positive Data for BARHEMSYS® Treatment of PONV Published in Anesthesia & Analgesia

Cambridge, UK and Indianapolis, US – 12 July 2019: Acacia Pharma Group plc (“Acacia Pharma”, the “Company”) (EURONEXT: ACPH) welcomes an editorial published in the leading peer-reviewed journal Anesthesia & Analgesia, accompanying the print publication of results from its positive Phase 3 clinical trial of BARHEMSYS® (intravenous amisulpride) as treatment of post-operative nausea & vomiting (PONV) in patients who had not received prior prophylaxis*.

In their editorial, entitled “Amisulpride: A New Dopamine Antagonist for Treatment of Postoperative Nausea and Vomiting”, Professor Gan and Dr Mouch, of the Department of Anesthesia at Stony Brook University Hospital, New York, highlight the positive data published by Candiotti et al in the same issue of the journal and comment that there is now “favorable evidence that amisulpride may be effective in both the prophylaxis and treatment of postoperative nausea and vomiting.”

The authors further review safety and cardiac conduction data published on amisulpride and conclude that it has “a similar adverse event profile compared to placebo” and “lower risks of corrected QT interval prolongation at clinically relevant doses.”

Dr Gabriel Fox, Chief Medical Officer of Acacia Pharma, welcomed the editorial: “We are delighted that Professor Gan and Dr Mouch have identified BARHEMSYS as worthy of an editorial in Anesthesia & Analgesia. We agree with their observation that ‘there remain few options for treatment after [PONV] has manifested, especially in those who have already received prophylaxis.’ We remain committed to bringing BARHEMSYS to patients as soon as possible and hope to secure its approval from the United States Food & Drug Administration in the first quarter of next year.”

About PONV

PONV is a common complication of surgery, occurring in approximately 30% of surgical patients and up to 80% of high-risk patients. It is associated with the use of anaesthetic gases and opioid pain-killers and is particularly common following gynaecological, abdominal, breast, eye and ear operations, especially those lasting an hour or more.

The Company estimates that approximately 65 million surgical procedures are conducted in the US each year that require injectable analgesia and are eligible for antiemetic use to prevent PONV. Based on market research, Acacia Pharma estimates that the total market in the US for prophylactic and rescue treatment comprises an estimated 34 million treatment events annually.

PONV has been ranked as the most undesirable of all surgical complications by patients and contributes significantly to patient anxiety and distress. PONV can delay hospital discharge; result in re-admission after in-patient procedures; and lead to day-case patients being admitted to hospital, all of which can result in significantly increased healthcare costs.
