NHS patients will soon be able to access Theramex’s once-a-day endometriosis pill Yselty (linzagolix), following final draft guidance from the National Institute for Health and Care Excellence (NICE).
The health technology assessment agency has recommended the at-home treatment be used to manage endometriosis symptoms in patients across England, Wales and Northern Ireland with a history of previous medical or surgical treatment for their endometriosis.
It will be given with add-back hormone therapy, which involves using low-dose hormone replacement therapy to minimise or eliminate menopause-like symptoms and bone loss.
Affecting approximately 1.5 million women in the UK, endometriosis occurs when tissue similar to the lining of the uterus grows elsewhere in the body. Patients can experience a range of symptoms, including dysmenorrhoea (painful cramping, usually in the lower abdomen), heavy bleeding and pelvic pain.
Yselty is designed to block the hormones that contribute to endometriosis symptoms. The drug is expected to be available in the coming months and could benefit more than 1,000 patients every year, according to NHS England.
NICE’s decision was supported by results from the EDELWEISS 3 study, in which Yselty used alongside add-back therapy demonstrated statistically significant reductions in both co-primary endpoints of non-menstrual pelvic pain and dysmenorrhea compared to placebo.
Sue Mann, national clinical director in women’s health for NHS England, said: “This is welcome news for women with endometriosis who haven’t found relief from previous therapies or surgery – it’s another treatment option which will help women take control of their health and better manage the symptoms of this often painful and debilitating condition.”
NICE’s final guidance on Yselty is set to be published on 25 June, after which the NHS must make the treatment available within 90 days.
The announcement comes less than two months after NICE recommended Gideon Richter’s Ryeqo (relugolix, estradiol and norethisterone) as the first long-term daily pill for endometriosis.
Commenting on the agency’s latest decision, Emma Cox, chief executive at Endometriosis UK said: “Historic lack of research into women’s health means those with endometriosis have far too few options for managing their sometimes debilitating pain and other symptoms of endometriosis.
“It’s good to see companies investing in research, and NICE approving a new drug for endometriosis, offering more choice for those considering medical menopause to manage symptoms.”
