  Purpose

Although declining in incidence, gastric/gastroesophageal cancer is still a commonly diagnosed malignancy in Canada. Patients who have undergone surgical resection for early disease have a high rate of local recurrence and distant spread. More than 50% of patients present with either locally advanced or metastatic disease. Patients with advanced disease have an extremely poor prognosis, with average survival times ranging from 3 - 9 months. Development of new therapeutic approaches for locally advanced or metastatic gastric/gastroesophageal cancer, is clearly needed.

Despite its proven efficacy, ECF (epirubicin, cisplatin, and infusional 5-fluorouracil [5-FU]) has not been widely adopted in North America and is likely due to the technical difficulties and inconvenience associated with infusional chemotherapy. This study will substitute the oral chemotherapy drug capecitabine for infusional 5-FU in addition to substituting intravenous cisplatin with carboplatin (ECC - epirubicin, carboplatin and capecitabine). It is hoped that these substitutions will not only reduce the typical ECF related adverse effects but also allow for a more convenient administration of outpatient chemotherapy. It is also hoped that the genetic correlates of this study may also identify specific populations that preferentially benefit from ECC treatment.

  Hide Detailed Description

Detailed Description:

Background Information:

Capecitabine is an orally administered systemic prodrug of 5'-deoxy-5-fluorouridine which is converted to 5-fluorouracil. Capecitabine is readily absorbed from the gastrointestinal tract and then hydrolyzed in the liver. Capecitabine has been studied in the treatment of gastric/gastroesophageal cancer in addition to a wide variety of other malignancies (e.g. GI, breast).

Objectives

Phase I:

Primary Objective:

  • To define the maximum tolerated dose (MTD) of capecitabine with combined fixed doses of epirubicin and carboplatin in patients with advanced solid cancers. With the identification of the MTD, determination of the recommended phase II dose will be made and used to further evaluate the specific anti-tumor activity of ECC in unresectable locally advanced and/or metastatic gastric/gastroesophageal cancer.

Secondary Objectives:

  • To describe the safety, toxicity profile, principle and dose-limiting toxicities (DLT) of ECC when given on this schedule; and
  • To determine the pharmacokinetic behavior of capecitabine when given in combination with epirubicin and carboplatin as part of the ECC regimen.

Phase II:

Primary Objective

  • To determine the anti-tumor activity of ECC when given at the RPTD in patients who have unresectable locally advanced and/or metastatic gastric/gastroesophageal cancer who have not received prior palliative chemotherapy.

Secondary Objectives

  • To further characterize the toxicity profile of the ECC regimen;
  • To determine time to progression, duration of response, and overall survival of patients on this study;
  • To determine the effects of thymidylate synthase (TS) polymorphisms on both toxicities and efficacy of ECC in prospectively genotyped patients;
  • To prospectively evaluate other potential pharmacogenetic correlates which may also play a role in augmenting toxicity, including MTHFR; and
  • To assess effects of uridine glucuronosyltransferase 2B7 (UGT 2B7) polymorphisms on epirubicin metabolism.

Study Design:

This is a Phase I/II trial that will study the safety as well as the efficacy of the ECC combination chemotherapy regimen.

Epirubicin: will be administered as an IV push at a fixed dose of 50mg/m2 on day 1 - repeated every 21 days

Carboplatin: will be administered IV, at a fixed dose with an AUC of 5 (over a 1-hour infusion in 500ml of 5% dextrose) on day 1 - repeated every 21 days

Capecitabine: will be administered as a twice daily oral medication (variable dose for phase I portion of the trial, but fixed dose for phase II portion of the trial) for 14 consecutive days (days 1-14) - repeated every 21 days

For the phase I portion of the study cohorts of 3 patients will be treated at each of 3 pre-determined dose levels of capecitabine and monitored for toxicity:

  • Dose level 1: 750 mg/m2 bid
  • Dose level 2: 850 mg/m2 bid
  • Dose level 3: 1000 mg/m2 bid
  • Dose level 4+: 25% dose escalation (rounded to the nearest twice a day dosing).

Statistical Analysis

Phase I:

Summary statistics such as frequency and intensity of toxicity occurring at each dose level will be provided. The percentage of patients developing DLT at each dose level will be computed. The dose-toxicity curve can be estimated accordingly using either parametric or non-parametric methods.

Phase II: A Simon's optimal two-stage phase II study will be conducted in patients with unresectable locally advanced or metastatic gastric or gastro-esophageal cancer at the RPTD of the ECC regimen. A total sample size of 43 patients will be required, 13 in the first stage and 30 in the second stage, if criteria for second stage accrual are met. If <=3/13 patients respond, this is deemed to correspond with the initial rejection limit and no further patients will be enrolled. If >=4/13 patients respond, an additional 30 patients will be enrolled in the second stage (total sample size = 43). Further statistical details are specifically outlined in Section 8 of the protocol. The response rate, standard error and its 95% confidence intervals (CI) will be calculated under the binomial distribution model. The efficacy of the regimen will then be evaluated by comparing the point estimates and 95% CI with historical data. Potential covariates for response will also be identified and evaluated via the logistic regression model. Kaplan-Meier estimates will be computed to estimate the secondary endpoints such as time to progression and survival. Cox-regression model can be applied incorporating covariates in the model. Fisher's exact test will be applied to compare the response rates between the different genetic TS polymorphisms groupings.

Stopping Rules:

Treatment will be discontinued and the patient will come off the trial therapy due to severe intercurrent illness, disease progression, unacceptable toxicity, patient request to stop, and/or if the physician deems it in the best interest of patient to discontinue.

Inclusion/Exclusion Criteria
