Abstract:
e13017 Background: Novel drugs that target HER2 receptors have shown promise in the treatment of Advanced breast carcinoma (BC). We study here the safety and efficacy of select monoclonal drugs (Mab) and tyrosine kinase inhibitors (TKIs) in the treatment of advanced BC. Methods: Following the PRISMA guidelines, we searched the literature on PubMed, Cochrane, Embase & clinicaltrials.gov. A total of 1054 articles were screened, and 6 studies were included. Results: In a phase III trial comparing Margetuximab (MAR) vs Trastuzumab (TRA), the overall survival (OS) and Progression free survival (PFS) was superior for MAR (21.6m Vs 19.8m & 5.7m Vs 4.4m respectively). However, the side effect profile is comparable for both drugs.Neutropenia (50 %) was a key problem in an ongoing trial including Zenocutuzumab (ZENO), resulting in dosage reduction. Similarly, phase III trials incorporating TKIs such as Neratinib (NER) and Tucatinib (TUC), there was improved OS (21m Vs 18.7, 24.7m Vs 19.2m respectively) as compared to Standard of care and chemotherapy. Regarding safety profile, these therapies are generally well tolerated with manageable side effects as listed in the table. Conclusions: Both monoclonal antibodies and tyrosine kinase inhibitors show clinically significant benefits in advanced HER2 positive breast carcinoma. However, more evidence and randomized clinical trials are needed to further establish their role in this rapidly evolving field.[Table: see text]
