Summary

This a Phase III trial designed to demonstrate that IV casopitant plus dexamethasone and ondansetron is more effective in the prevention of vomiting and nausea then dexamethasone and ondansetrone alone following the administration of moderately emetogenic chemotherapy.

Clinical Details

Official title: A Study of Single Dose Intravenous Casopitant in Combination With Ondansetron and Dexamethasone for the Prevention of Oxaliplatin Induced Nausea and Vomiting.

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

Primary outcome: Subject diary completed during cycle 1 to assess vomiting and the use of rescue medication.

Secondary outcome:

Subject diary completed during cycle 1 to assess nausea during the 120 hour assessment period; Subject diary completed to assess vomiting and use of rescue medication during cycle 2.

Assessed in the acute and delayed phases of Cycle 1: The proportion of subjects who achieve a complete response.

Assessed in the overall phase of Cycle 2: The proportion of subjects who achieve a complete response.

Assessed in the overall, acute and delayed phases of Cycle 1:

Maximum nausea score, assessed by a Visual Analogue Scale (VAS). • The proportion of subjects who receive rescue medication. • The proportion of subjects who vomit/retch. • The proportion of subjects reporting significant nausea, defined

The proportion of subjects reporting significant nausea, defined as a maximum nausea score ≥ 25 mm on the VAS. • The proportion of subjects reporting nausea, defined as a maximum nausea score ≥ 5 mm on the VAS.

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

The proportion of subjects achieving total control, defined as complete responders who had no nausea. • Time to first anti-emetic rescue medication. • Time to first emetic event.

Time to event is defined as the time elapsed from the start of the oxaliplatin infusion to the first event.

If a subject withdraws prematurely or dies during the first 120 hours, then the time of withdrawal or death will be considered to be their time to first event, and will be censored.

Health Outcomes Endpoints assessed in Cycle 1: • The impact on subjects' daily life activities in the overall phase, as assessed by the FLIE questionnaire.

Severity of nausea in the overall, acute, and delayed phases assessed by a categorical scale.

PK Endpoints assessed in Cycle 1 (subset of subjects only)

Single-dose pharmacokinetic parameters: AUC(0-∞), AUC(0-t), Cmax, tmax, t1/2 for casopitant and metabolites GSK525060, GSK517142 and GSK631832; and CL and Vdss for casopitant only.

progression into subsequent cycles of therapy within the study, only if all of the following criteria apply:

- Subject understands the nature and purpose of this study and the study procedures and

has signed an informed consent form for this study to indicate this understanding.

- At least 18 years of age.

- Is scheduled to receive oxaliplatin at a dose between 85 mg/m² and 130 mg/m² in their

first cycle of therapy for the treatment of colorectal cancer, administered as a single IV dose over 2-6 hours on Day 1 only, in combination with 5FU/LV, or in combination with capecitabine.

- An Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.

- Hematologic and metabolic status adequate for receiving an oxaliplatin-based

moderately emetogenic regimen and meeting the following criteria:

- Total Neutrophils ≥1500/mm³ (Standard units : ≥1. 5 x 10^9/L)

- Serum Creatinine ≤1. 5 mg/dL (Standard units : ≤132. 6 µmol/L) OR

- Creatinine clearance ≥60 mL/min

Creatinine clearance must be calculated using the Cockcroft-Gault formula:

Clcreat (ml/min) = (140-age [yr]) x body wt [kg] 72 x serum creatinine [mg/dl] For females: multiply creatinine clearance by a factor of 0. 85. OR Clcreat (ml/min) = K x (140-age [yr]) x body wt [kg] serum creatinine [µmol/L] K=1. 05 for females K=1. 23 for males

- Liver enzymes must be below the following limits:

- Without known liver metastases: Aspartate aminotransferase (AST) and/or alanine

aminotransferase (ALT) ≤2. 5 x ULN.

- With known liver metastases: AST and/or ALT ≤5. 0 x ULN.

- Is willing and able to complete daily components of the Subject Diary for Cycle 1

and Cycle 2 without assistance from others.

- A female subject is eligible to enter and participate in this study if she is

of:

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 on Cycle 1 Day 1. Women of childbearing potential must also 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 the physician, are as follows:

- male partner who is sterile prior to the female subject's entry into the study and is

the sole sexual partner for that female subject;

- oral contraceptives (e. g., oral, injectable, or implantable) with double-barrier

method of contraception consisting of spermicide with either condom or diaphragm for a period after the trial to account for a potential drug interaction (minimum of six weeks);

- double-barrier method of contraception consisting of spermicide with either condom or

diaphragm;

- intra-uterine device with a documented failure rate of less than 1% per year;

- complete abstinence from intercourse for two weeks before exposure to the

investigational product throughout the clinical trial, and for a period after the trial to account for elimination of the drug (minimum of 3 days);

- if subject indicates they will remain abstinent during the period described above,

they must agree to follow GSK guidelines for the consistent and correct use of an acceptable method of birth control should they become sexually active.

Exclusion Criteria:

- A subject will not be eligible for initial inclusion in this study if any of the

following criteria apply, or will not be eligible for subsequent cycles of therapy if any of the following criteria become applicable:

- Has received cytotoxic chemotherapy prior to the first study cycle of chemotherapy,

with the exception that previous adjuvant therapy with 5FU/LV or capecitabine is permitted, provided that the last dose of adjuvant therapy was completed at least 6 months prior to receiving the first dose of study medication or investigational product.
