EU approves Trodelvy for metastatic triple-negative breast cancer.
The EC’s decision is supported by results from the Phase III ASCENT study, where Trodelvy reduced the risk of death by 49% and improved median overall survival to 11.8 months versus 6.9 months with physician’s choice of chemotherapy (HR: 0.51; 95% CI: 0.41-0.62; p<0.0001). these data also showed a statistically significant and clinically meaningful 57% reduction in the risk of death or disease worsening and improved median progression free survival (pfs) to 4.8 months from 1.7 months seen with physician’s choice of chemotherapy alone among all randomized patients, which included those with and without brain metastases (hr: 0.43; 95% ci: 0.35-0.54; p><0.0001)
The most common Grade 3 or higher adverse reactions were neutropenia (49.5%), leukopenia (12.0%), diarrhea (10.7%), anemia (10.1%), febrile neutropenia (6.6%), fatigue (5.2%), hypophosphatemia (5.2%), nausea (4.1%) and vomiting (3.0%). The Trodelvy U.S. Prescribing Information has a BOXED WARNING for severe or life-threatening neutropenia and severe diarrhea.
“The metastatic stage of TNBC is particularly challenging to treat and until now we have urgently needed new treatment options for people in Europe living with this condition,” said Dr Véronique Diéras, Senior Medical Oncologist Head, Breast Cancer Group, Department of Medical Oncology, Centre Eugène Marquis, Rennes, France. “Today’s approval including second-line metastatic TNBC is significant for the community as it’s another important step forward in helping women with this disease live longer.”
