Olanzapine 2.5 vs 5 mg in Quadruplet Nausea/Vomiting Prophylaxis Before High-Dose Melphalan

- NCT06588413
- Lead Sponsor
- Augusta University
- Brief Summary
Patients who receive a chemotherapy called melphalan are at high risk of having nausea and vomiting. A medication called olanzapine has been shown to decrease nausea and vomiting after chemotherapy. A previous research study found the 10 mg dose of olanzapine (combined with 3 standard medications used routinely to prevent nausea/vomiting) to be effective for patients who received melphalan chemotherapy, but several other studies have shown many patients have a side effect of sleepiness (e.g., sedation) with that dose of the medication. Our study will compare two lower doses of olanzapine (5 mg and 2.5 mg) in combination with the 3 standard medications used to prevent nausea/vomiting in the patients who receive melphalan chemotherapy to determine which dose is effective in preventing nausea and vomiting with the lowest amount of sleepiness side effect.
- Detailed Description
This study is a randomized, double-blinded trial comparing olanzapine 2.5 mg vs 5 mg in combination with standard triplet antiemetic prophylaxis in patients with multiple myeloma who are receiving high-dose melphalan conditioning chemotherapy before autologous stem cell transplantation to determine chemotherapy-induced nausea and vomiting (CINV) and sedation outcomes.

Group Intervention Description Olanzapine 2.5 mg Olanzapine Olanzapine 2.5 mg dose to be given on the day of high-dose melphalan and three days after Olanzapine 5 mg Olanzapine Olanzapine 5 mg dose to be given on the day of high-dose melphalan and three days after
- Primary Outcome Measures
Name Time Method Complete Response From day of chemotherapy (acute phase) through 5 days after chemotherapy (delayed phase) The primary objective is to compare the percentage of patients achieving chemotherapy-induced nausea and vomiting (CINV) complete response (CR), where CR is defined as no emesis and no more than mild nausea (\</=1 score on a 4-point categorical scale \[0 = none, 1 = mild, 2 = moderate, and 3 = severe\]) during the overall assessment period (defined as the day of chemotherapy through 5 days after chemotherapy).
- Secondary Outcome Measures
Name Time Method Complete Protection From day of chemotherapy (acute phase) through 5 days after chemotherapy (delayed phase) Complete protection (CP) defined as no emesis, no more than mild nausea, and no use of breakthrough antiemetic agents
Incidence of patients with no more than minimal sedation From day of chemotherapy (acute phase) through 5 days after chemotherapy (delayed phase) Incidence of patients with no more than minimal nausea From day of chemotherapy (acute phase) through 5 days after chemotherapy (delayed phase) Number of emetic episodes From day of chemotherapy (acute phase) through 5 days after chemotherapy (delayed phase) Number of breakthrough antiemetic doses From day of chemotherapy (acute phase) through 5 days after chemotherapy (delayed phase)
