MHRA Grants Historic Approval for Non-Hormonal Menopause Treatment

The Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom has made a significant advancement in women's health by granting approval for elinzanetant (Lynkuet, Bayer), a non-hormonal drug aimed at alleviating moderate to severe vasomotor symptoms, including hot flushes and night sweats, associated with menopause. This decision, announced on July 10, 2025, marks a groundbreaking moment as it is the first global authorization of a non-hormonal therapy for this condition, catering to women who are unable or choose not to use hormone-based treatments.

Elinzanetant functions as a dual antagonist of neurokinin-1 (NK1) and neurokinin-3 (NK3) receptors. By modulating the activity of kisspeptin/neurokinin B/dynorphin (KNDy) neurons in the hypothalamus, the drug aims to restore the thermoregulatory balance that is often disrupted by declining estrogen levels during menopause. The treatment is administered via a once-daily tablet, offering a convenient option for patients.

The approval was supported by clinical evidence from three phase 3 trials—OASIS 1, 2, and 3—that collectively involved over 1,400 women aged 40 to 65. According to the reports, a daily dosage of 120 mg of elinzanetant resulted in statistically significant reductions in both the frequency and severity of vasomotor symptoms when compared to placebo. Improvements were noted as early as week 1 and continued through to week 52 of treatment. Moreover, participants reported enhancements in sleep quality and overall quality of life, suggesting a holistic benefit of the therapy.

In terms of safety, most adverse events associated with elinzanetant were classified as mild to moderate. The most frequently reported side effects included headache, fatigue, and somnolence. The MHRA has recommended monitoring liver function during the treatment course to ensure patient safety. Julian Beach, the interim executive director of healthcare quality and access at the MHRA, emphasized that elinzanetant has met the agency's rigorous standards for safety, quality, and effectiveness.

The decision to approve elinzanetant comes amid increasing discussions about menopause management options. Dr. Sarah Johnson, a Professor of Women's Health at London University, noted that this approval could provide an essential alternative for women facing menopause challenges. "The introduction of elinzanetant is a pivotal step in diversifying treatment options available for menopausal symptoms, particularly for those who prefer to avoid hormonal therapies," she stated.

Despite the positive reception of the approval, some healthcare professionals remain cautious. Dr. Michael Thompson, a leading endocrinologist at Cambridge University, suggests that while the data is promising, long-term effects and the drug's impact on diverse populations still require further investigation. He stated, "We must remain vigilant and continue post-marketing surveillance to fully understand the implications of introducing a new therapy into such a sensitive demographic."

The MHRA plans to publish a comprehensive summary of product characteristics and patient information on its website within a week of the approval. Clinicians have been encouraged to report any suspected adverse reactions via the Yellow Card scheme, which is designed to enhance pharmacovigilance.

As the healthcare community anticipates the availability of elinzanetant, the approval underscores an evolving landscape in menopause treatment, where non-hormonal options are becoming increasingly viable. The implications of this approval extend beyond the UK, as it may prompt other regulatory bodies worldwide to consider similar treatments, potentially transforming the management of menopausal symptoms globally. The ongoing discourse surrounding menopause treatment continues to highlight the need for accessible, effective options that cater to a diverse range of patient preferences and needs.
