The study endpoints were overall response rate (ORR: complete response [CR]+partial response [PR]) and disease control rate (DCR: CR+PR+stable disease [SD]) in neoadjuvant and metastatic settings. Overall survival (OS) and safety were evaluated for all settings.Results: Of 91 patients (neoadjuvant: 12, adjuvant: 61, metastatic: 18), efficacy evaluation in 29 patients (neoadjuvant: 12/12, metastatic: 17/18) demonstrated an ORR and DCR of 100%, respectively, in the neoadjuvant setting, and an ORR of 64.7% and DCR of 70.6%, respectively, in the metastatic setting. At a median follow-up of 21.6 months (range: 2.1 to 49.9 months), median OS was not reached in neoadjuvant and adjuvant settings, and it was 30.4 months in metastatic settings. At least one adverse event (AE) was reported in 59.3% of patients. Anemia, thrombocytopenia, lymphopenia, and neutropenia were the most common hematological AEs reported while hyperglycemia and alteration in liver function tests were the most common non-hematological AEs. NDLS-based treatment was well tolerated without any new safety concerns.Conclusion: Nanosomal docetaxel lipid suspension-based chemotherapy was efficacious and well tolerated in the treatment of breast cancer. Further, NDLS is being evaluated prospectively in patients with triple-negative breast cancer (ClinicalTrials.gov: NCT03671044).Keywords: DoceAqualip, NDLS, nanosomal docetaxel lipid suspension, breast cancer
