Trial Information

A Phase I Trial of Capecitabine Rapidly Disintegrating Tablets and Concomitant Radiation Therapy in Children With Newly Diagnosed Brainstem Gliomas and High Grade Gliomas



- Estimate the maximum tolerated dose of capecitabine rapidly disintegrating tablets
(RDT) administered concurrently with radiotherapy in young patients with newly
diagnosed, nondisseminated intrinsic brain stem glioma or high-grade glioma.

- Describe the dose-limiting toxicity in patients treated with this regimen.


- Describe the safety profile of this regimen.

- Characterize the pharmacokinetics of capecitabine RDT in these patients.

- Explore the exposure-response relationship for measures of safety and effectiveness
using pharmacokinetic and pharmacodynamic models.

- Describe the antitumor activity of this regimen observed in these patients.

- Estimate distributions of progression-free survival and survival in patients treated
with this regimen.

- Characterize radiographic changes in tumor, using MRI, perfusion and diffusion MRI, and
positron emission tomography (PET) scans, in patients treated with this regimen.

OUTLINE: This a multicenter, dose-escalation study of capecitabine rapidly disintegrating
tablets (RDT).

Patients undergo radiotherapy once daily, 5 days a week, for approximately 6 weeks.
Beginning within 24 hours of starting radiotherapy, patients also receive oral capecitabine
RDT twice daily on days 1-21. Treatment with capecitabine RDT repeats every 21 days for 3

Cohorts of 3-6 patients receive escalating doses of capecitabine RDT until the maximum
tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2
of 3 or 2 of 6 patients experience dose-limiting toxicity.

Beginning in week 12, patients receive capecitabine RDT at a fixed dose twice daily on days
1-14. Treatment repeats every 21 days for 3 courses in the absence of disease progression or
unacceptable toxicity.

Patients undergo blood collection periodically during course 1 for pharmacokinetic
correlative studies. Patients also undergo MRI, and rapid perfusion/diffusion MRI at
baseline and periodically during study for radiographic correlative studies.

After completion of study treatment, patients are followed periodically for 2 years.

PROJECTED ACCRUAL: A total of 18 patients will be accrued for this study.
