Abstract
Background Chemotherapy-induced nausea and vomiting is a common and unpleasant treatment-related side effect reported by cancer patients receiving chemotherapy. Akynzeo® or NEPA (NEtupitant + PAlonosetron) is the first fixed combination of netupitant and palonosetron that targets both critical pathways involved in emesis while providing a convenient, single oral dose therapy. The current study aimed to assess the effectiveness and safety of NEPA in a real-world setting in India. Methodology This was an open-label, multicenter, prospective, single-arm study conducted at six different locations across India. The study included patients of either gender, aged ≥18 years, naive to chemotherapy, scheduled to receive highly or moderately emetogenic chemotherapy (HEC/MEC), and scheduled to receive oral NEPA, as determined by the investigator. Results A total of 360 people were screened and enrolled in the study. HEC was prescribed to 289 (81.64%) patients, while MEC was prescribed to 65 (18.36%) patients. Complete response was achieved in 94.92% of patients during the acute phase, 95.20% during the delayed phase, and 93.22% during the overall phase. During the overall phase, 92.73% and 95.38% of patients on the HEC and MEC regimens, respectively, achieved complete response. Adverse events were reported in 3.88% of patients. Conclusions Oral NEPA was found to be effective in the Indian real-world setting, eliciting a >90% complete response with HEC and MEC regimens across the acute, delayed, and overall phases.
