Oral Capecitabine and Temozolomide (CAPTEM) for Newly Diagnosed GBM
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety and efficacy of administering the medication capecitabine along with temozolomide when you start your monthly regimen of oral temozolomide for the treatment of your newly diagnosed glioblastoma multiforme (GBM).
Capecitabine is an oral chemotherapy that is given to patients with other types of cancer. The study will evaluate whether the dosage of 1500 mg/m2 of capecitabine is tolerable after radiation, when taken along with temozolomide. It will also try to determine if the medication capecitabine helps patients respond to treatment for a longer period of time compared to just temozolomide alone, which is the standard of care.

Detailed Description
There were an estimated 22,000 new cases of brain cancers in 2015 in the United States, and 15,000 deaths (Howlader et al., 2014). Glioblastoma (WHO IV), and Anaplastic Astrocytoma (WHO III), are the most common brain cancers, respectively, representing over 70% of all malignant gliomas (ABTA, 2015).
Though rare, there is no cure, and the prognosis for these tumors is poor. Survival at 5 years for all CNS cancers is approximately 33.3 % (Howlader et al., 2014). For GBM, the most lethal of the tumors, with the current standard of care median survival is 14.6 months (Walid, 2008). Relative survival with GBM at five years is approximately only 5% (Ostrom et al. CBTRUS 2014).
For newly diagnosed tumors, the current standard of care recommends a multi-modal approach with surgery to remove the tumor, when possible, followed by 6 weeks of radiation and a concurrent daily dose of temozolomide (Stupp et al. 2005). This is known as the Stupp protocol (Stupp et al. 2005). Patients then have a one-month rest period with no treatment, followed by "maintenance" temozolomide, given five days out of every 28 days, for a minimum of six months. Some providers keep patients on temozolomide beyond 6 months, or until disease progression.
Therefore, more therapies are needed to help improve survival, reduce time to recurrence and improve quality of life for these patients. This trial proposes to improve the current standard of care by enhancing the efficacy of an active drug temozolomide, currently used for treatment of GBM.

Outcome Measures
Primary Outcome Measures
- Progression-free survival (PFS) [6 months]
PFS will be estimated by calculating the proportion of patients who are alive at 6 months from treatment commencement and are progression-free.
- Overall Survival (OS) [4 years]
OS will be calculated as the time from treatment initiation to the date of death.
Secondary Outcome Measures
- Composite overall response rate (CORR) through the Response Evaluation Criteria In Solid Tumors (RECIST) [6 months]
Subjects will be classified according to the RECIST criteria, which is a composite of MRI changes, clinical response and changes in steroid use.
- Toxicities will be tabulated and graded according to the NCI Common Toxicity Criteria (CTCAE) version 4.03. [6 months]
Proportions of subjects experiencing these toxicities will be estimated using standard methods for proportions.

-
Prior chemotherapies for newly diagnosed GBM or AA, other than temozolomide during radiation.

-
Serious medical or psychiatric illness preventing informed consent or treatment (e.g., serious infection)

Prior malignancies in the last 5 years other than curatively treated carcinoma in-situ previously treated with curative intent (cancer free for the past one year).
-
Performance status, KPS < 70
-
Inability to swallow pills and capsules
-
Concurrent chemotherapy or treatment for the active disease, including devices such as Optune, high dose vitamin supplements, or any other chemotherapy
-
Patients taking concomitant medications such as Coumadin and phenytoin medications, need to be excluded because of interactions with capecitabine
-
Patients with previously documented CAD will need to be evaluated by cardiology prior to start to help risk stratify for capecitabine tolerance
-
Patients with renal insufficiency or hepatic insufficiency
-
Patients with coagulopathies
-
Women who are pregnant or lactating.
