Intravenous Palonosetron With Radiotherapy and Concomitant Temozolomide

Study Overview
=================
Brief Summary
-----------------
1. Purpose and objective: To determine the safety and tolerability of palonosetron in the prevention of radiation induced nausea and vomiting (RINV) in primary glioma patients receiving radiation (RT) and concomitant temozolomide (TMZ). To determine the efficacy of palonosetron in primary glioma patients receiving six weeks of RT and concomitant TMZ To evaluate the effect s of palonosetron on the quality of life of primary glioma patients receiving six weeks of RT and Concomitant TMZ. 2. Study activities and Population group: We will conduct a phase II single arm trial of Palonosetron (PALO) for the prevention of RINV in primary malignant glioma patients receiving radiation therapy (RT) and concomitant temozolomide (TMZ). All eligible patients should receive a planned total dose of 54-60 GY of radiation and 75 mg/m2 of daily temozolomide for a total of six weeks of treatment. For each week of radiation patients will receive a single 0.25 mg intravenous dose of palonosetron 30 minutes before each week of radiation fraction. This schedule will be repeated for each week of radiation for a total of 6 weeks. Forty subjects with gliomas will participate. 3. Data analysis and risk/safety issues: The frequency of toxicity will be summarized by type and the most severe grade experienced. The complete response rate, defined as the proportion of patients with no emetic episode or use of rescue medication while receiving radiation and concomitant temozolomide, will be estimated with a 95% confidence interval.

Detailed Description
-----------------
We will conduct a phase II single arm trial of Palonosetron (PALO) for the prevention of RINV in primary malignant glioma patients receiving radiation therapy (RT) and concomitant temozolomide (TMZ). All eligible patients should receive a planned total dose of 54-60 GY of radiation and 75 mg/m2 of daily temozolomide for a total of six weeks of treatment. For each week of radiation patients will receive a single 0.25 mg intravenous dose of palonosetron approximately 30 minutes before each week of radiation fraction. This schedule will be repeated for each week of radiation for a total of 6 weeks. After the start of radiation the type of rescue medication will be up to the investigator's discretion (however given the results of recent published phase II study by Navari et. al. we recommend using olanzapine for rescue medication). All patients will be given written informed consent.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety and Tolerability of Palonosetron as Determined by the Number of Participants Who Experience Unacceptable Toxicity | The number of participants with unacceptable toxicity defined as ≥grade 3, non-hematologic toxicities that are possibly, probably or definitely related to the study regimen. | 6 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Complete Response | The percentage of participants with a complete response defined as no emetic episode or use of rescue medication while receiving radiation (XRT) and concomitant temozolomide (TMZ). | 6 weeks | 
| Change in the Functional Living Index - Emesis (FLIE) Score From Baseline to Each Week of Radiation (XRT) and Temozolomide (TMZ) Treatment | The FLIE is a 18-item validated questionnaire for assessing the effects of chemotherapy-induced nausea and emesis on quality of life and daily functioning. The raw score range is 18-126 with higher scores indicating better quality of life. For each week of XRT and TMZ, the change from baseline was calculated by subtracting the baseline score from the mean of the day 1, 3 and 6 scores. A negative change represents worsening in quality of life due to nausea and emesis. | 6 weeks | 
| Percentage of Participants With a Osoba Nausea Module Maximum Standardized Score of Zero for Each Week of Radiation (XRT) and Temozolomide (TMZ) | Percentage of participants with a Osoba nausea module maximum standardized score of zero for each week of radiation (XRT) and Temozolomide (TMZ). The Osoba nausea module is a 5-item questionnaire assessing the effect of nausea on quality of life and daily functioning. Raw scores range from 5-20 and have been converted to standardized scores (0-100) using the formula: std_score = round((raw_score - 5) * 6.66). Lower scores indicate better quality fo life. The maximum standardized score of all nausea scores collected during the week (days 1, 3 and 6) was used for this outcome. | 6 weeks | 
| Percentage of Participants With a Osoba Vomiting/Retching Module Maximum Standardized Score of Zero for Each Week of Radiation (XRT) and Temozolomide (TMZ) | Percentage of participants with a Osoba vomiting/retching module maximum standardized score of zero for each week of radiation (XRT) and Temozolomide (TMZ). The Osoba vomiting/retching module is a 5-item questionnaire assessing the effect of vomiting/retching on quality of life and daily functioning. Raw scores range from 5-20 and have been converted to standardized scores (0-100) using the formula: std_score = round((raw_score - 5) * 6.66). Lower scores indicate better quality fo life. The maximum standardized score of all vomiting/retching scores collected during the week (days 1, 3 and 6) was used for this outcome. | 6 weeks |
