Preventing chemotherapy-induced nausea and vomiting in patients with lung cancer: efficacy of NEPA (netupitant-palonosetron), the first combination antiemetic
A partir des données de 2 essais cliniques incluant des patients atteints d'un cancer du poumon traité par cisplatine ou carboplatine, cette étude évalue l'efficacité d'un traitement combinant nétupitant et palonosétron pour prévenir les nausées et vomissements induits par une chimiothérapie à base de sels de platine
Purpose : Patients receiving platinum-based chemotherapy are at high risk of chemotherapy-induced nausea and vomiting (CINV), a distressing side effect of treatment. This post-hoc subgroup analysis of two pivotal trials evaluated the efficacy of NEPA in preventing CINV in subsets of patients with lung cancer who received cisplatin or carboplatin. Methods : In each study, the efficacy endpoints complete response (CR; defined as no emetic episodes and no rescue medication) and no significant nausea (NSN; defined as a score of < 25 mm on a visual analog scale of 0–100 mm) during the acute (0–24 h), delayed (25–120 h), and overall (0–120 h) phases post-chemotherapy in cycle 1 (study 1) and cycles 1–4 (study 2) were assessed. Safety was evaluated by recording treatment-emergent adverse events (AEs) and treatment-related AEs. Results : NEPA treatment resulted in high CR rates across the acute, delayed, and overall phases (cisplatin: > 88% overall CR; carboplatin: > 75% overall CR), with higher CR rates for NEPA-treated patients than those receiving palonosetron; moreover, CR rates were sustained over multiple chemotherapy cycles (> 75%). High rates of NSN observed during cycle 1 (> 79%) were also maintained over multiple chemotherapy cycles. NEPA was well tolerated in all patients. Conclusions : NEPA appears to be effective and well tolerated in patients with lung cancer receiving platinum-based chemotherapy, across the acute, delayed, and overall phases and throughout multiple cycles. As a highly effective oral combination antiemetic agent administered as a single dose once per cycle, NEPA may offer a convenient, simplified prophylactic antiemetic.
