A nervous-appearing 68-year-old female presents to the infusion center to receive her 1st cycle of AC → T for newly diagnosed breast cancer. Her past medical history includes hypertension, hypothyroidism, and generalized anxiety. Her risk factors for chemotherapy-induced nausea and vomiting include all of the following EXCEPT …

25% 1. Female Gender 25% 2. Anxiety 25% 3. Highly emetogenic chemotherapy 25% 4. Advanced Age

1 Highly Emetogenic Chemotherapy

• Pre-chemotherapy (Prevent Acute N/V):

5-HT3 Receptor Antagonist NK-1 Receptor Antagonist • Post-chemotherapy (Prevent Delayed N/V): Dexamethasone NK-1 Receptor Antagonist

A 70-year-old male with a PMH of a-fib, MI, CAD, chronic alcoholism, and GERD presents for cycle #1 of carboplatin + paclitaxel → bevacizumab for advanced lung cancer. His risk factors for CINV include …

Syndromes Associated With CINV (1 of 2)

• Acute emesis – Usually starts within 1-2 hours after administration – Peak intensity within 5-6 hours, resolution 12-24 hours • Delayed Emesis – Peak onset 48-72 hours after chemotherapy, diminishing after 1-3 day – Occurs in 50-90% of patients treated with highly emetogenic regimens – 35-70% with moderately emetogenic therapy – More common with platinum containing regimens • Breakthrough CINV – Nausea and vomiting occurring despite preventive therapy

4 Syndromes Associated With CINV (2 of 2)

• Anticipatory emesis – Associated with uncontrolled emesis during prior chemotherapy • Refractory CINV – N/V occurring during subsequent cycles of chemotherapy when prophylaxis or rescue therapy has failed in previous cycles • Potential to cause: – Dehydration and electrolyte imbalance – Impaired health-related quality of life • Negative impact on activities of daily living – Rehospitalization

Chemotherapy-Induced Emesis Risk Factors

• Patient-related risk factors1 – Younger age – Female gender – No/minimal prior history of alcohol use – Prior CINV –Anxiety • Treatment-related risk factors1,2 – Moderate to high emetogenicity of chemotherapy agents or regimens – Moderate to high drug dose

5 Risk Factors for CINV Chemotherapy-Specific Factors

• Use of moderately or highly emetogenic regimens such as – AC (Anthracycline + cyclophosphamide) - High – Carboplatin-based regimens - Moderate – -based regimens - High – Cyclophosphamide-based regimens - Moderate – FOLFOX/FOLFIRI - Moderate – ABVD - Moderate • Short IV infusion time • Repeated cycles of chemotherapy

7 Dexamethasone

• Mechanism of action unknown • More effective than placebo and prochlorperazine in some controlled trials • Effective against vomiting caused by variety of anticancer agents, including cisplatin •  efficacy in combination antiemetic regimens • No significant side effects when used at recommended doses and schedules • Possible insomnia and hyperglycemia • No  incidence of infections or change in frequency and site of metastases • Inexpensive

The Best Dose of Dexamethasone?

• Rx: Dexamethasone • Indication: Acute emesis • Patients: Cisplatin • Results: All received ondansetron 8 mg IV randomized to single IV dexamethasone doses Dexamethasone N No Emesis No Nausea 4 mg 133 69% 61% 8 mg 136 69% 61% 12 mg 130 79% 67% 20 mg 131 83% 71% • Conclusions: No difference in adverse effects. Dexamethasone 20 mg should be the standard (20 vs 12 mg: 4% observed – 95% CI 5-14%)

The Italian Group. J Clin Oncol. 2000;18(19):3409-3422.

8 Mechanism of Action of Pharmacologic Therapies • Older agents of low therapeutic index – Dopamine RA’s • Dopamine receptor blockage in – Cannabinoids • antiemetic effect on enterochromaffin cells

•5HT3 RAs – Binding to 5HT3 receptors in periphery & CNS • Primary mechanism for acute emesis control • NK-1 RA’s – Predominantly central action • agents must cross blood-brain barrier

Perez EA, et al. J Clin Oncol. 1998;16:754-760.

Mechanisms for Differences in

Efficacy of 5-HT3 antagonists

• Palonosetron has greater efficacy in prevention of acute & delayed CINV •Why?

– Higher binding affinity & longer t1/2 cannot fully account for this – Palonosetron has a unique binding site on the

5-HT3 receptor • Increases its affinity at other sites

Jin Y et al. Eur J Cancer Care (Engl). 2012 Apr 22. Epub ahead of print.

10 Palonosetron Indication

• Palonosetron 0.25 mg is indicated for: – The prevention of acute N/V associated with initial and repeat courses of moderately and highly emetogenic cancer chemotherapy – The prevention of delayed N/V associated with initial and repeat courses of moderately emetogenic cancer chemotherapy • The first and only 5-HT3 receptor antagonist specifically indicated for delayed CINV

• APR group: – CR was 87% for the acute period – 73% for the delayed period – 73% for the overall period in 120 patients receiving the APR regimen

• Patients without nausea was: OLN: 87%, acute; 69%, delayed; 69%, overall; APR: 87%, acute; 38%, delayed; and 38% overall. There were no grade 3 or 4 toxicities

• OLN was comparable to APR in the control of CINV in patients receiving HEC. Nausea was better controlled with OLN

29 Key Points

• Treatment of the nausea associated with emetogenic chemotherapy is still a problem. Olanzapine appears to be an effective agent. • Prevention is the goal of management • The development of serotonin antagonists and the neurokinin-1 antagonist, aprepitant, have resulted in a significant improvement in the treatment of CINV • Corticosteroids are useful antiemetics, they provide synergy with 5-HT3 antagonists and play an important role in the treatment of delayed emesis • Prescribe drug combinations for the entire time of risk • Research must continue until all nausea and vomiting associated with cancer are prevented. The goal of therapy is NO N / V for at least 5 days following chemotherapy • Guidelines have been established to help manage populations of patients however outliers do exist
