Phase 2
Fosrolapitant Combined With Palonosetron to Prevent Trastuzumab Rezetecan Related CINV
Condition(s) studied
Chemotherapy-Induced Nausea and Vomiting (CINV)
Investigational drug(s) / intervention(s)
Fosrolapitant and Palonosetron Hydrochloride for Injection: D1: Fosrolapitant and Palonosetron Hydrochloride for Injection (218 mg of pholorapitant and 0.25 mg of palonosetron hydrochloride), IV, administered 1 hour before chemotherapy.
Observe for two treatment cycles (C1-C2); Starting from the first dose, record the patient's daily vomiting frequency, severity of nausea, and medication adherence.
Study summary
This study is a prospective, single-arm, multicenter, exploratory clinical trial divided into a screening phase, a treatment phase, and a follow-up phase. The study aims to evaluate the efficacy and safety of foslorapitant palonosetron for injection in preventing nausea and vomiting caused by treatment with recanituzumab. All patients who meet the inclusion criteria and do not meet any exclusion criteria are eligible for enrollment in this study and are scheduled to receive targeted therapy, antiemetic treatment, and follow-up.
Dosage Regimen Eligible subjects will receive a prophylactic antiemetic regimen consisting of foslorapitant and palonosetron.
The dosage regimen is as follows:
Day 1 (D1): Foslorapitant and palonosetron (218 mg foslorapitant and 0.25 mg palonosetron hydrochloride), administered intravenously (IV) 1 hour prior to chemotherapy.
Observe for two treatment cycles (C1-C2); Starting from the first dose, record the patient's daily vomiting frequency, severity of nausea, and medication adherence.

11. Patients with other factors deemed by the investigator to be unsuitable for participation in this study, such as any physiological or psychological conditions that may increase study risks, affect patient adherence to the protocol, or interfere with the patient's ability to complete the trial.
Primary outcome measure(s)
- Overall Complete Response (CR) Rate — 0 to 120 hours after trastuzumab rezetecan infusion within Cycle 1 and Cycle 2 (each treatment cycle is 21 days)
