Bayer AG NAExpanded Canadian approval for LYNKUET to treat breast cancer-related hot flashes opens a new patient population, likely increasing sales.

Bayer Inc. announced that Health Canada has expanded the market authorization of LYNKUET (elinzanetant) to treat moderate to severe vasomotor symptoms caused by adjuvant endocrine therapy related to breast cancer. The approval makes LYNKUET the first treatment option in Canada for this patient population, building on its July 2025 authorization for menopausal vasomotor symptoms. The expanded indication is supported by the Phase III OASIS-4 study, which evaluated elinzanetant in women receiving adjuvant endocrine therapy who experienced moderate to severe vasomotor symptoms. LYNKUET is a once-daily oral dual neurokinin-1 and neurokinin-3 receptor antagonist, and Bayer notes that hormone therapy is not recommended for women with a history of hormone receptor-positive breast cancer, making non-hormonal options an important clinical need.
