Phase: Phase 3

Status: Completed

Sponsored by: GlaxoSmithKline

Official(s) and/or principal investigator(s):

Summary

This is a Phase III trial designed to demonstrate that casopitant when added to dexamethasone and ondansetron is more effective in the prevention of vomiting then dexamethasone and ondansetron alone, in patients who receive a cisplatin-based highly emetogenic chemotherapy.

Clinical Details

Official title: A Phase III Multicenter, Randomized, Double-Blind, Active-Controlled, Parallel Group Study of the Efficacy and Safety of the Intravenous and Oral Formulations of the Neurokinin-1 Receptor Antagonist, Casopitant, Administered in Combination With ZOFRAN and Dexamethasone for Prevention of Chemotherapy-Induced Nausea and Vomiting in Cancer Subjects Receiving Highly Emetogenic Cisplatin-Based Chemotherapy

Study design: Prevention, Randomized, Double-Blind, Active Control, Parallel Assignment, Safety/Efficacy Study

Primary outcome: To demonstrate that triple therapy casopitant, ondansetron and dexamethasone provides an improved CR rate over ZOFRAN and dexamethasone alone during the 120 hours following a cisplatin-based HEC regimen.

Secondary outcome:

Complete response over 120 hours following subsequent chemotherapy cycles Use of rescue medication over 120 hours following all chemotherapy cycles Impact on daily life activities over 120 hours, assessed using a subject diary questionnaire

The proportion of subjects who achieve a complete response during the acute (0-24 hrs.) and the delayed (24-120 hrs.) phase following the first cycle of HEC

The proportion of subjects who achieve a complete response over the first 120 hours, during the acute (0-24 hrs.), the delayed (24-120 hrs.), and the overall (0-120 hrs.) phase following subsequent cycles of HEC.

Maximum nausea score (to assess the severity of nausea), as assessed by a Visual Analogue Scale (VAS) over the first 120 hours and in the acute and delayed phases following each cycle of HEC.

Time to first antiemetic rescue medication, defined as the time elapsed from the start of the HEC regimen to the first use of antiemetic rescue medication.

If a subject withdraws prematurely during the first 120 hours, then the time of withdrawal will be considered to be their time to first use of antiemetic rescue medications, and will be censored.

Time to first emetic event, defined as the time elapsed from the start of administration of HEC to the first emetic episode.

If a subject withdraws prematurely during the first 120 hours, then the time of withdrawal will be considered to be their first emetic episode, and will be censored.

The proportion of subjects who receive rescue medication.

The proportion of subjects reporting significant nausea defined as a maximum nausea score greater than or equal to 25 mm on the VAS.

The proportion of subjects reporting nausea defined as a maximum nausea score greater than or equal to 5 mm on the VAS.

The proportion of subject achieving total control, defined as complete responders who had no nausea.

The impact on subjects' daily life activities for the first 120 hours following the first cycle of chemotherapy as assessed by the FLIE questionnaire.

Subject satisfaction with the prophylactic antiemetic regimens, and the willingness of subjects to use the same treatment during future chemotherapy, as assessed by the Subject Satisfaction\Willingness Assessment in the Subject Diary.

Nausea as assessed by a categorical scale, over the first 120 hours following HEC administration.

Assessment of the safety and tolerability of casopitant through: routine physical exam, routine clinical laboratory tests, clinical monitoring and adverse events reporting.

The proportion of subjects who vomit/retch.

The proportion of subjects achieving complete protection, defined as complete responders who had no significant nausea.

study cycle.

- Women of childbearing potential; must commit to consistent and correct use of an

acceptable method of birth control; GSK acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of a physician, are as follows:

1. non-childbearing potential (i. e., physiologically incapable of becoming pregnant, including any female who is post-menopausal. For purposes of this study, postmenopausal is defined as one year without menses)

2. child-bearing potential: must have a negative serum pregnancy test result or negative urine dipstick pregnancy test within 24 hours prior to the first dose of investigational product of cycle 1 day 1, and agrees to one of the following:
