FDA grants Trodelvy accelerated approval for triple-negative breast cancer.- Immunomedics

Immunomedics announced that the FDA has granted accelerated approval to Trodelvy (sacituzumab govitecan-hziy) for the treatment of adult patients with triple-negative breast cancer that has spread to other parts of the body. Patients must have received at least two prior therapies before taking Trodelvy. The FDA approved Trodelvy based on the results of a clinical trial of 108 patients with metastatic triple-negative breast cancer who had received at least two prior treatments for metastatic disease. Trodelvy was granted accelerated approval, which enables the FDA to approve drugs for serious conditions to fill an unmet medical need based on a result that is reasonably likely to predict a clinical benefit to patients. Further clinical trials are required to verify and describe Trodelvy's clinical benefit.The efficacy of Trodelvy was based on the overall response rate (ORR) – which reflects the percentage of patients that had a certain amount of tumor shrinkage. The ORR was 33.3%, with a median duration of response of 7.7 months. Of the patients with a response to Trodelvy, 55.6% maintained their response for 6 or more months and 16.7% maintained their response for 12 or more months. The most common side effects for patients taking Trodelvy were nausea, neutropenia, diarrhea, fatigue, anemia, vomiting, alopecia (hair loss), constipation, decreased appetite, rash and abdominal pain.
