BARHEMSYS was approved by the US Food and Drug Administration (FDA) for the treatment and prevention of postoperative nausea & vomiting (PONV) on 26 February 2020.

'We are excited to announce today that BARHEMSYS is now available in the US for the millions of patients each year who suffer from PONV,' commented Mike Bolinder, Acacia Pharma's CEO. 'BARHEMSYS is the first and only antiemetic to be approved for the rescue treatment of PONV in patients who have failed prior prophylaxis with an agent of a different class using current standard of care and we estimate there are approximately 16 million such surgical patients each year in the US that go on to suffer from PONV despite receiving prophylaxis.1-3 We believe there will be strong demand for BARHEMSYS as US healthcare institutions seek to address surgical backlogs created by the coronavirus crisis and are very happy to make this new therapy available in the US.'

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 anesthetic gases and opioid painkillers and is particularly common following gynecological, abdominal, breast, eye, and ear operations, especially those lasting an hour or more. PONV has been ranked as the most undesirable of all surgical complications in some patient surveys, even worse than pain.4

Acacia Pharma estimates that approximately 65 million surgical procedures are conducted in the US each year that are eligible for antiemetic use to prevent PONV. Based on market research, Acacia Pharma estimates that the total market in the US for high-risk prophylactic and rescue treatment comprises an estimated 34 million patients annually.3

BARHEMSYS is indicated in adults for: treatment of PONV in patients who have received antiemetic prophylaxis with an agent of a different class or who have not received prophylaxis prevention of PONV, either alone or in combination with an antiemetic of a different class www.BARHEMSYS.com
