The Christie NHS Foundation Trust Supportive care [in cancer] is the prevention and management of the adverse effects of cancer and cancer treatment The landscape of cancer is changing More and more people are living longer with cancer Proactive supportive care can improve survival 1.

Adapted from CM Lindley et al. Qual Life Res. 1992;1:331-40. Who is more at risk? • Female gender • Young age • Anxious personality • Minimal alcohol use (caveat ≥ 5 drinks/week is protective) • History of emesis during pregnancy • History of motion sickness • History of previous CINV Morrow GR, et al. Support Care Cancer. 2002;10:96-105. Why optimal CINV treatment and prevention is important • Nausea and vomiting are common and feared symptoms among cancer patients • Up to 80% of patients will experience chemotherapy-induced nausea and vomiting (CINV) without prophylactic therapy • Nausea and vomiting can lead to deteriorated nutritional status • Inadequate emesis control may lead to anticipatory sickness Aziz F.

NK-1 receptor antagonists: How do they work? • NK1 receptors antagonists exert their strongest antiemetic properties through central inhibition of the emesis pattern generator • This is one of the final common mechanisms involved in activation and coordination of the vomiting reflex • There is substantial evidence for involvement of substance P throughout the CINV response • NK1 – RAs prevent the sensitisation of NK1 receptors by substance P • This decreases the likelihood of vomiting • NK-1 RAs also increase the efficacy of steroids and 5-HT3 antagonists Saito R, Takano Y, Kamiya HO.

Am J Med 2001;111:106S-112S Antiemetics in 2018: practical issues 1. Good – if not perfect – antiemetic agents are available 2. Quality evidence exists that should guide all oncologists in preventing “CINV” 3. Still, many patients experience emesis 4. So do evidence-based guidelines actually work? CINV, chemotherapy-induced nausea and vomiting. Controlling emesis in chemotherapy: What’s new? Controlling Emesis during Chemotherapy: New findings which can affect Practice • New Agents • New Data • Updated Guidelines • Resource Utilisation Developing new antiemetic agents: what would be ‘the ideal’ / where are ‘the gaps’? • Better control during the ‘delayed phase’ • Single dose day 1 • Effective control over multiple chemotherapy cycles • Flexibility: Agents with different metabolic pathways to avoid drug-drug interactions Controlling Emesis during Chemotherapy: New agents • Rolapitant – NK1 receptor antagonist with different metabolic pathway – Highly selective agent • NEPA – Fixed-dose combination of netupitant (NK1 receptor antagonist) + palonosetron (5HT3 receptor antagonist) – Highly selective agents • Olanzapine – A non-specific, non-selective, neuroleptic agent – Antiemetic and anti-nausea properties – Questions persist regarding dose and role Controlling Emesis during Chemotherapy: New Agents • Rolapitant – NK1 receptor antagonist with different metabolic pathway – Highly selective agent • NEPA • Fixed-dose combination of netupitant (NK1 receptor antagonist) + palonosetron (5HT3 receptor antagonist) • Highly selective agents • Olanzapine • A non-specific, non-selective, neuroleptic agent • Antiemetic and anti-nausea properties • Questions persist regarding dose and role F C Rolapitant Background 3 O N H O CF3 N H .
