A new era of menopause treatment await to be on the horizon . This calendar week , drugmaker Bayer publish the effect of two successful Phase III trials testing its observational drug elinzanetant as a treatment for blistering trice . The drug is now poise to become the first non - hormonal medication of its variety approved in the earth .
Hot instant and night sweatsare common symptom of change of life , feign around 80 % of women in their life-time . officially known as vasomotor symptom , hot flash lamp are characterize by sudden bout of warmth , rubor , and sweating , typically around the face , neck opening , and chest ( night travail are exchangeable , but occur at night and while sleeping ) . These sequence can be deeply uncomfortable , and more serious case are thought to raise the risk of pitiful eternal sleep and low . Though hot flashes do decline over time , they often last for at least two eld , and some woman will know them for a decade or longer , according to theMayo Clinic .
Historically , hot flashes have been effectively treated with internal secretion therapy , which aims to replace the point of estrogen and progesterone that decline with menopause . Starting in the late 1990s , however , large - scale trial began to show that hormone therapy could potentially raise the risk of infection of other health problems , including philia disease , knocker Crab , and shot , in menopausal women — result that soon lead to a large and sustained drop cloth - off in the treatment . Later studies and more recent analysesof the information have found that these hazard may have been overdraw and can be safely mitigated . Organizations like the North American Menopause Societycurrently statethat the welfare of hormonal intervention for hot flashes outweigh any potential scathe for most cleaning woman who set about therapy before old age 60 and/or within ten year of their last point . But endocrine therapy remains much less popular than before , and there are some cleaning woman who have a in high spirits risk of complication from it , such as those with a history of breast cancer .

Women unwilling or unable to practice hormones for their hot flashes have had limited other options to appointment , such as low doses of certain SSRIs . But in the other 2010s , scientist finally started to unpick some of the mechanisms underlying hot flashes . They distinguish that a group of neuron that produced kisspeptin , neurokinin B ( NKB ) , and dynorphin ( bang as KNDy neurons ) were pivotal in causing the flush relate with crushed estrogen layer . Later study found that blocking the activity of some receptors on these cells could safely abridge hot flashes . And in May 2023 , the Food and Drug AdministrationapprovedAstellas Pharma ’s fezolinetant , the first drug that treats red-hot flashes by block one of these receptor , NK3 .
Bayer ’s elinzanetant obstruct both NK3 and NK1 receptors , a three-fold - action designing that scientists have hoped would not only lose weight red-hot flashes but also the sleeping trouble often associated with climacteric . In the tumid Phase III trials of the drug , publishedThursday in the journalJAMA , those hopes look to have been validate .
The studies involved over 700 women in their forty and fifty diagnose with moderate to dangerous live photoflash , who were randomise to have elinzanetant or a placebo . Across both test , researchers see that women taking elinzanetant ( a once - daily pill ) have a significant reducing in hot instant relative to ascendency . By the end of the study , 26 weeks afterwards , over 80 % of women on the drug see a more than 50 % reduction in symptoms , including women who switched to the drug 12 workweek into their trial . participant also reported fewer sleep disturbances than women engage a placebo , and they reported a high increase in their menopause - related quality of life . Elinzanetant appear to be safe as well , with the most coarse adverse events ( compared to placebo ) in those take the drug being headaches and weariness .
“ Elinzanetant has the potentiality to provide a well - tolerated and efficacious nonhormonal treatment option to address the unmet wellness needs of many menopausal individuals with moderate to severe [ hot flashes ] , ” the researchers of theJAMApaper write .
The results come after equally hopeful findings from the caller ’s other Phase III tryout of elinzanetant , announcedearlier this March . And the company is now design to submit data from all three work to regulators to ensure the drug ’s approval as a treatment for moderate to severe live flashes — an approval that should be in the handbag , barring any major surprise .
As important as the comer of these drugs is , though , there is the thorny issue of cost . Fezolinetant ’s list price is presently around $ 550 a month , and it has receivedlimited insurance coverageto date , harmonise to Forbes . These drugs could eventually be widely cover , especially as more put down the market , but for now , there is the luck that many eligible patients will not be able-bodied to afford them .
