On Wednesday, AstraZeneca announced the launch of Trastuzumab deruxtecan, a groundbreaking therapy for adult patients grappling with unresectable or metastatic HER2-positive breast cancer, developed in collaboration with Daiichi Sankyo. This engineered HER2-directed antibody-drug conjugate (ADC) stands as a beacon of hope for those who have previously undergone anti-HER2 regimens.
Breast cancer, identified by the World Health Organization as the most diagnosed cancer globally, has seen a 40% surge in incidence in India over the past 25 years. Trastuzumab deruxtecan addresses this critical medical need, offering a targeted approach by specifically binding to HER2 receptors and delivering a cytotoxic payload directly to cancer cells.
Dr. Meenu Walia, Vice Chairman-Medical Oncology at Max Super Speciality Hospital, hailed Trastuzumab deruxtecan as a significant advancement in HER2-positive breast cancer treatment, emphasizing its efficacy and breakthrough clinical outcomes observed globally. The therapy’s introduction is supported by positive results from the global Phase III DESTINY-Breast03 trial.
Dr. Anil Kukreja, Vice-President, Medical Affairs and Regulatory at AstraZeneca India, underscored the urgent need to provide transformative medicine to patients with HER-2 positive metastatic breast cancer who have already progressed on initial anti-HER2 targeted treatment. He expressed AstraZeneca’s commitment to redefining cancer care and eradicating cancer as a cause of death.
Trastuzumab deruxtecan, representing a significant stride in the fight against breast cancer, demonstrated a 72% reduction in the risk of disease progression or death compared to trastuzumab emtansine (T-DM1) in primary results published in The New England Journal of Medicine. Import and marketing approval from the Drug Controller General of India in May 2023 adds to the optimism surrounding this transformative therapy.
