Event Summary

Canada — Health Canada has expanded the market authorization of Bayer's elinzanetant (brand name Lynkuet) to treat moderate to severe hot flashes and night sweats in breast cancer patients. The drug was first approved in July 2025 for menopausal women, and the new authorization, effective August 14, 2026, follows a review of the OASIS-4 Phase 3 trial. The trial enrolled 395 women on endocrine therapy for breast cancer and showed significant reductions in vasomotor symptoms and sleep disturbances. Elinzanetant is a non-hormonal neurokinin receptor antagonist that targets KNDy neurons. The approval addresses a significant unmet need, as breast cancer patients cannot use hormone replacement therapy. Bayer's drug is not yet publicly funded in Canada. The decision was supported by oncologists including Dr. Christine Brezden-Masley of Sinai Health System and Dr. Dave Cescon of Princess Margaret Cancer Centre.
