Every-other-day palonosetron plus aprepitant for prevention of emesis following induction chemotherapy for acute myeloid leukemia: A randomized, controlled study from the "Rete Ematologica Pugliese"

2023 updated MASCC/ESMO consensus recommendations: prevention of nausea and vomiting following multiple-day chemotherapy, high-dose chemotherapy, and breakthrough nausea and vomiting

PURPOSE

This review is an update of the MASCC/ESMO 2015 recommendations for the prophylaxis of acute and delayed nausea and vomiting induced by multiple-day chemotherapy, high-dose chemotherapy, and breakthrough nausea and vomiting.

METHODS

A systematic literature search was conducted using PubMed from June 1, 2015, through February 1, 2023.

RESULTS

We identified 56 references (16 were duplications or invalid), leaving 40 manuscripts for this search. The panel classified level I evidence (three manuscripts) and level II evidence (14 manuscripts). High-dose chemotherapy and stem cell transplant were discussed in four of these manuscripts, and multiple-day chemotherapy treatment in 15. Some manuscripts covered both topics. Additionally, a search for breakthrough nausea and vomiting resulted in 12 "hits." No new relevant studies were identified.

CONCLUSIONS

The recommendations for patients receiving high-dose chemotherapy with stem cell transplants and patients undergoing multiple-day cisplatin were updated. For patients receiving high-dose chemotherapy for stem cell transplant, a combination of a 5-HT3 receptor antagonist with dexamethasone and aprepitant is recommended. Olanzapine could be considered part of the antiemetic regimen. Patients receiving multiple-day cisplatin should receive a 5-HT3 receptor antagonist plus dexamethasone plus aprepitant plus olanzapine. For patients experiencing breakthrough nausea and vomiting, the available evidence suggests using a single dose of olanzapine daily for 3 days.

One-Day Versus Three-Day Dexamethasone with NK1RA for Patients Receiving Carboplatin and Moderate Emetogenic Chemotherapy: A Network Meta-analysis

BACKGROUND

The dexamethasone (DEX)-sparing strategy, which limits administration of DEX to day one, is reportedly non-inferior to conventional antiemetic regimens comprising multiple-day DEX. However, the usefulness of the DEX-sparing strategy in triplet antiemetic prophylaxis (neurokinin-1 receptor antagonist [NK1RA] + serotonin receptor antagonist [5HT3RA] + DEX) for carboplatin and moderate emetogenic chemotherapy (MEC) has not been clarified.

PATIENTS AND METHODS

We systematically reviewed randomized controlled trials that examined the efficacy of antiemetics for preventing chemotherapy-induced nausea and vomiting associated with carboplatin and MEC. We conducted a network meta-analysis to compare the antiemesis efficacy of three-day DEX with NK1RA (3-DEX + NK1RA) and one-day DEX with NK1RA (1-DEX + NK1RA). The primary outcome was complete response during the delayed phase (CR-DP). The secondary outcome was no nausea during the delayed phase (NN-DP).

RESULTS

Seventeen trials involving 4534 patients were included. The proportion who experienced CR-DP was 82.5% (95% credible interval [CI], 73.9-88.6) and 73.5% (95% CI, 62.8-80.9) among those who received 3-DEX + NK1RA and 1-DEX + NK1RA, respectively. There was no significant difference between the two regimens. However, 3-DEX + NK1RA tended to be superior to 1-DEX + NK1RA, with an absolute risk difference of 9.0% (95% CI, -2.3 to 21.1) in CR-DP and 24.7% (95% CI: -14.9 to 54.6) in NN-DP. 3-DEX + NK1RA also tended to be superior to 1-DEX + NK1RA in patients who received carboplatin-based chemotherapy, for whom the absolute risk difference was 12.3% (95% CI, -3.2 to 30.7).

CONCLUSIONS

Care is needed when administering the DEX-sparing strategy in combination with NK1RA to patients receiving carboplatin and non-carboplatin MEC.

Every-other-day palonosetron plus aprepitant for prevention of emesis following induction chemotherapy for acute myeloid leukemia: A randomized, controlled study from the "Rete Ematologica Pugliese"

BACKGROUND

Compared with older 5-HT₃ receptor antagonists, palonosetron requires fewer drug administrations to prevent chemotherapy-induced nausea and vomiting (CINV) following multiple-day chemotherapy. We conducted a phase II multicenter study comparing palonosetron plus aprepitant to palonosetron alone in patients undergoing a range of induction chemotherapy regimens for acute myeloid leukemia (AML).

METHODS

Patients were randomized to palonosetron (0.25 mg) every other day until the last dose of chemotherapy alone or with aprepitant on days 1-3. Patients mainly received an anthracycline on days 1-3 plus cytarabine administered for 5-10 days. The primary end point was complete response (CR; no emesis and no rescue medication) over the whole study period (days of chemotherapy plus two additional days). Unplanned analysis of time to anti-emetic treatment failure (TTF) was also performed.

RESULTS

Of the 134 patients enrolled in the study, 130 were evaluable: 68 subjects received palonosetron plus aprepitant and 62 received palonosetron alone. Although the primary end point of CR was similar between the treatment arms (72% vs 69%; P = .55), a higher proportion of patients treated with palonosetron plus aprepitant were free from nausea during the whole study period (43% vs 27%; P = .03). There was also a significant difference in favor of the two-drug regimens in TTF (median: 5 days vs 3 days; P = .03).

CONCLUSIONS

The study suggests that every-other-day palonosetron plus 3-day aprepitant can add clinical benefit to the control of CINV caused by multiple-day, corticosteroid-free chemotherapy for AML. In this challenging setting of CINV, further investigations of palonosetron in combination with aprepitant administered with an expanded schedule are warranted.
