(CAPTEM)
What this study is about
The purpose of this study is to evaluate the safety and effectiveness of administering the medication capecitabine along with temozolomide when you start your monthly regimen of taken by mouth temozolomide for the treatment of your newly diagnosed glioblastoma multiforme (GBM). Capecitabine is an taken by mouth chemotherapy that is given to patients with other types of cancer.
View original scientific description
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.
Interventions
DRUG
Capecitabine
Capecitabine at 1500 mg/m2
DRUG
Temozolomide
Temozolomide at 150 mg/m2 - 200 mg/m2
Primary outcome measures
Progression-free survival (PFS)
Time frame: 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)
Time frame: 4 years
OS will be calculated as the time from treatment initiation to the date of death.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Be capable of giving informed consent.
- Have a pathology proven diagnosis of any of newly diagnosed Glioblastoma Multiforme WHO IV
- Have completed the first part of standard of care chemo-radiation (Stupp), for 6 weeks, and not started the maintenance phase of temozolomide
- Agree to use effective barrier contraception while on treatment and for 2 months thereafter, if of childbearing potential
- Have a life expectancy \> 3 months
- Be between the ages of 18 to 74
- Have a performance status KPS 70 or greater
- Be able to swallow pills and capsules
- Be able to tolerate oral chemotherapeutic medications, with no health threatening allergies or side effects, based on lab and clinical findings
- Have adequate bone marrow function, liver function and renal function before commencing therapy
Exclusion criteria
- Prior chemotherapy with capecitabine or temozolomide for other prior malignancies. Patients previously treated with continuous infusion 5-FU or any schedule of DTIC, which are similar to capecitabine and temozolomide, respectively, will be excluded.
- Prior chemotherapies for newly diagnosed GBM or AA, other than temozolomide during radiation.
- Patients with a history of severe hypersensitivity reaction to capecitabine, 5-FU, temozolomide (i.e. anaphylaxis or anaphylactic reactions),
- 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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
