Safety of a short-term infusion of fosnetupitant in patients with gastrointestinal and breast cancer: a prospective study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFosnetupitant, a neurokinin-1 receptor antagonist, is used to prevent chemotherapy-induced nausea and vomiting (CINV) in patients undergoing highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC). Previous phase III trials demonstrated the non-inferiority of its 30-minute infusion to fosaprepitant in efficacy and a favorable safety profile.
methodsThis was a single-arm, phase II study to investigate the safety of a 15-minute infusion of fosnetupitant in patients with gastrointestinal and breast cancer. Patients who had received their dose of fosnetupitant in a 30-minute infusion without developing an allergic reaction were eligible and received their next fosnetupitant dose for 15 minutes. The primary endpoint was the incidence of an allergic reaction during the first 15-minutes infusion, and the secondary endpoints were the incidence of injection site reaction (ISR), the incidence of a grade ≥ 3 treatment-related adverse event (TRAE) with fosnetupitant, and complete response (CR) rate.
resultsThe study period was from February 17, 2023 to June 20, 2023. In an exploratory analysis, medical records from the end of the study period to December 31, 2023 were retrospectively evaluated to assess the time-saving effect and safety of the short-term infusion of fosnetupitant. Fifty-six patients with gastrointestinal and 14 patients with breast cancer were enrolled, one of whom with breast cancer did not receive study treatment at her own request. No allergic reactions occurred during the 15-minutes infusion. Furthermore, there were no allergic reactions across all 280 short-term injections (Table 1). Additionally, no ISR or grade 3 or higher TRAE were reported. The CR rate was 87.0%.
conclusionShort-term infusion of fosnetupitant, administered over 15 minutes, was demonstrated to be safe and effective for patients receiving HEC or MEC (Japan Registry of Clinical Trials Trial ID: jRCT1041220144).
