Clinical Trial Summary

RATIONALE: Gabapentin may prevent or reduce delayed nausea and vomiting caused by chemotherapy. It is not yet known whether gabapentin is more effective than a placebo in preventing nausea and vomiting.

PURPOSE: This randomized phase III trial is studying the side effects of gabapentin and to see how well it works compared with a placebo in preventing nausea and vomiting in patients receiving chemotherapy.

Description:

OBJECTIVES:

• To evaluate the effectiveness of gabapentin in controlling delayed chemotherapy-induced nausea and vomiting (CINV) in patients receiving highly emetogenic chemotherapy as defined by the percentage of complete responders (no emetic episodes and no rescue medication) on days 2 through 6 (five days after receipt of highly emetogenic chemotherapy) compared to an effective prophylactic regimen.

• To evaluate the effectiveness of gabapentin in controlling delayed CINV in patients receiving highly emetogenic chemotherapy as defined by the percentage of complete responders (no emetic episodes, no more than mild nausea, and no rescue medication) on days 2 through 6 compared to an effective prophylactic regimen.

• To compare the effectiveness of these regimens in controlling acute CINV on day 1 of treatment in these patients.

• To compare the use of rescue agents in these patients.

• To determine the tolerability of gabapentin in these patients.

• To evaluate the effect of gabapentin for delayed chemotherapy-induced nausea and vomiting on symptom distress and functional abilities in these patients.

• To compare alternative endpoints and methods for assessing nausea and vomiting and to determine how these measures compare to patient's satisfaction with symptom control, distress and function.

OUTLINE: This is a multicenter study. Patients are stratified according to gender, age (< 50 years vs > 50 years), history of alcoholism (yes vs no), and history of motion sickness or history of pregnancy induced nausea/vomiting (yes vs no). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive oral dexamethasone with 5HT3 receptor antagonist and oral gabapentin once daily on day 1 of chemotherapy. Patients then receive oral dexamethasone twice daily with or without 5HT3 receptor antagonist on days 2-4, and oral gabapentin either two or three times daily on days 2-5 of chemotherapy.

• Arm II: Patients receive oral dexamethasone with 5HT3 receptor antagonist and oral placebo once daily on day 1 of chemotherapy. Patients then receive oral dexamethasone twice daily with or without 5HT3 receptor antagonist on days 2-4, and oral placebo either two or three times daily on days 2-5 of chemotherapy.

Patients complete a Functional Living Index - Emesis questionnaire, an overall satisfaction survey, and a side effect experience diary at baseline and on day 6. Patients also complete a nausea and vomiting diary at baseline and periodically during study therapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Comparison of Percentage of Complete Responders	Complete response being defined as no emetic episodes and no use of rescue therapy for days 2 through 6. If a patient does not complete the study or does not provide complete data, they will be assumed to be a non-responder.	Days 2 through 6	No
Secondary	Complete Response	The primary analysis described above was repeated using a slightly different alternate definition of complete response: no emetic episodes, no more than a mean of 2.5 on the nausea numeric analogue scale (0 - 10 (As bad as it could be)), and no rescue agents.	Days 2-6	No
Secondary	Comparison of Percentages of Complete Responders on Day 1, vs. Days 1 Through 6 vs. Days 2 Through 6.	The percentages of complete responders on day 1, vs. days 1 through 6 vs. days 2 through 6 will be compared between arms. Complete response being defined as no emetic episodes and no use of rescue therapy. If a patient does not complete the study or does not provide complete data, they will be assumed to be a non-responder.	Days 1 through 6	No
Secondary	Comparison of the Percentage of Patients Experiencing Emetic Episodes and the Percentage Needing Rescue Agents	The percentage of patients experiencing emetic episodes and the percentage needing rescue agents was compared between groups.	Days1 through 6	No
Secondary	Comparison of Sum of the Daily Distress Questions as Well as the Individual Daily Responses	The sum of the daily distress questions as well as the individual daily responses from the Nausea and Vomiting Diary (NVD) on a 0-10 scale (Lower score is better) will be compared.	Days 1 through 6	No
Secondary	Level of Satisfaction for the Control of Nausea.	Level of satisfaction for the control of nausea with the mean severity of nausea over the six days in the diary (on a 0 - 10 scale, higher the better) as well as the nausea subscale on the Functional Living Index - Emesis (FLIE) questionnaire ( 1-7 scale, lower the better)	Days 1 through 6	No
Secondary	Comparison of Daily Complete Response Endpoints	Daily complete response is defined as no emetic episodes and no use of rescue therapy.	Days 1 through 6	No
