Effectiveness of antiemetic triplet therapy with aprepitant, palonosetron, and dexamethasone for gynecologic cancer patients receiving carboplatin and paclitaxel: a prospective single-arm study

Abstract

Purpose

There is no positive evidence for the efficacy of antiemetic triplet therapy with aprepitant (APR), palonosetron (PALO), and dexamethasone (DEX) for moderate emetogenic chemotherapy, especially for gynecologic malignancies. Thus, the present study evaluated the efficacy of this triplet therapy in patients receiving carboplatin and paclitaxel (CP) for gynecologic malignancy.

Methods

Seventy patients with gynecologic cancer receiving CP were enrolled into a prospective single-arm study with APR (125 mg on day 1, 80 mg on days 2–3), PALO (0.75 mg), and DEX (20 mg) before initiating chemotherapy. The primary endpoint was delayed complete response (CR) rate, i.e., no vomiting and no rescue, at 24–120 h after chemotherapy administration.

Results

Seventy patients were enrolled. The delayed CR rate was 97.1% (68/70). No serious adverse events were observed. Younger patient age (≤50 years) tended to be associated with a poor delayed CR rate.

Conclusions

This study demonstrated a notable efficacy of antiemetic triplet therapy with APR, PALO, and DEX in female patients receiving CP. Further evaluation with a larger phase III trial is warranted.
