Xonvea® launch in the UK

Alliance Pharma plc (AIM: APH), the international specialty pharmaceutical company, announces that it has today launched Xonvea, its prescription product for the treatment of nausea and vomiting of pregnancy (NVP), in the UK. Xonvea is a new licensed medicine available in the UK for women with NVP where conservative management has failed.

NVP is the most common medical condition in pregnancy affecting approximately 751,923 women in the UK each year, according to the Office of National Statistics and the Royal College of Obstetricians and Gynaecologists1,2. Research shows that up to 40% of pregnant women report symptoms of NVP sufficiently severe to interfere with daily life3-6 and that symptoms can be compared in severity to the nausea associated with chemotherapy7. Reported feelings of anxiety and depression from NVP have been shown to approach levels seen in women with post-natal depression3,8.

The Royal College of Obstetricians and Gynaecologists states that severe NVP is one of the most common reasons for pregnant women to be admitted to hospital2. In 2016-2017, there were 33,071 hospital admissions for NVP in England, resulting in 36,171 bed days according to the NHS9.

Professor Catherine Nelson-Piercy, consultant obstetric physician, commented:

"I am delighted that at last the UK has a licensed medication for the treatment of nausea and vomiting of pregnancy where conservative treatment has failed. This delayed release formulation of doxylamine and pyridoxine has been used in millions of pregnant women worldwide. Primary and secondary care doctors caring for pregnant women in the UK are now able to prescribe Xonvea, affording women in the UK a licensed option when it comes to managing this often debilitating condition. In women who do not respond completely to Xonvea, doctors can prescribe other anti-sickness drugs recommended by National Clinical Guidelines."

Peter Butterfield, Alliance Pharma's Chief Executive Officer, said:

"The launch of Xonvea is a significant milestone for Alliance and I'm delighted that we have today made the product available in the UK. There is no other licensed treatment for nausea and vomiting of pregnancy in the UK so this is excellent news for patients and clinicians as it fulfils a significant unmet medical need."

Alliance in-licensed Xonvea from Duchesnay Inc. of Canada for the UK in 2015. Xonvea's combination of doxylamine and pyridoxine is recommended as a first-line pharmacotherapy in the USA and Canada and has been prescribed to over 33 million women in more than 40 years3,10-15.

Éric Gervais, Duchesnay's Executive Vice-President, added:

"With the launch of Xonvea, Duchesnay is proud to provide women in the UK with something they have been without for years: a licensed treatment to help relieve nausea and vomiting of pregnancy."
