Olanzapine-based, dexamethasone-sparing antiemetic regimen for breast cancer patients with metabolic risk factors

Official title: Efficacy of an Olanzapine Based Dexamethasone-sparing Regimen in Breast Cancer Patients With Metabolic-risk Factors: A Randomized, Controlled Trial

Run by Alexandria University · NCT07743827 · Data updated 2026-11-12

This study tests whether an olanzapine-containing antiemetic plan can match the usual dexamethasone-containing approach in preventing delayed chemotherapy-induced nausea and vomiting for breast cancer patients with metabolic risk factors.

Is this trial a fit for you?

Likely a good fit

Women aged 18 or older with stage I–III breast cancer, planned for AC chemotherapy, and with metabolic risk factors such as diabetes, prediabetes, obesity, or metabolic syndrome.

Probably not a fit

Patients who do not respond to olanzapine or who have contraindications to olanzapine or corticosteroids may not benefit.

What this trial studies

This clinical trial compares an olanzapine-based antiemetic regimen to the standard dexamethasone-containing regimen in women with stage I–III breast cancer receiving highly emetogenic AC chemotherapy and who have metabolic risk factors. The goal is to see if the olanzapine approach is non-inferior for preventing delayed-phase nausea and vomiting while reducing metabolic toxicity. The regimen includes pantoprazole, olanzapine, and dexamethasone as components of antiemetic prophylaxis. The study addresses persistent delayed emesis in a population at higher metabolic risk and explores multi-receptor antiemetic strategies. Outcomes likely focus on nausea/vomiting control, safety, and metabolic profiles.

Why it matters

Potential benefit: If successful, patients may experience similar protection against delayed nausea and vomiting with lower metabolic side effects.

How similar studies have gone: Prior antiemetic strategies using multi-drug regimens have shown benefit; this olanzapine-based dexamethasone-sparing approach is being tested for non-inferiority in a metabolic-risk population.
