Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age eighteen years or older
  • Histological defined unresectable cholangiocarcinoma of hilar region of the liver
  • Patients should have evaluable disease on one or more imaging modalities (CT scan, MRI, and/or PET) since this will be necessary for radiation treatment planning. However, because the borders of these tumors are sometimes difficult to define precisely, measurable disease is not required (see Section 9.1 for definitions of evaluable and measurable disease).
  • The maximum tumor dimension should be less than 6 cm.
  • Patients with pathologically enlarged perihepatic regional lymph nodes are allowed.
  • Prior surgical resection is allowed if there is gross disease remaining
Show all 22Show fewer
  • Adjuvant chemotherapy is allowed at least 1 month after completion of radiation therapy if any grade 3 or higher toxicity has resolved
  • Percutaneous biliary drains and biliary stents are allowed
  • Performance status of ECOG 0-1 (see Appendix I)
  • Life expectancy greater than 6 months
  • Subject must have normal organ and marrow functions as defined below

Who cannot join

  • Patients who have had prior chemotherapy
  • Patients who have had external beam radiation to the region of liver hilar previously.
  • Patients receiving any other investigational agents
  • Patients with known metastases
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to capecitabine.
  • Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Show all 9Show fewer
  • Patients who are not candidates for gold marker seeds placement due to position of the tumor or co-existing medical condition.
  • Pregnant or lactating women and women of child-bearing potential who are not using an effective method of birth control

About this study

Official title: Phase I Dose Escalation Trial of External Beam Radiation and Cyberknife Radiosurgery Boost With Concurrent Capecitabine for Hilar Cholangiocarcinoma (Klatskin Tumor)

The purpose of this study is to test the safety of giving external beam radiation, followed by a Cyberknife radiosurgery boost at different dose levels, together with a chemotherapy drug called capecitabine. The dose of Cyberknife radiosurgery boost will be made higher slowly in this protocol. Patients with hilar cholangiocarcinoma (Klatskin tumor), which is not amenable for surgical removal, are eligible.

The hypothesis is that highly focused high dose radiation delivered using Cyberknife in conjunction with traditional radiation and chemotherapy can improve outcome in this patient population.

Read the detailed description

This is a dose escalation study which will escalate the dose of Cyberknife radiosurgery boost after external beam radiation of 45 Gy with concurrent capecitabine. The three dose levels are 4 Gy x5, 5 Gy x5 and 6 Gy x 5, with 3 patients at each dose level. Dose-limiting toxicity (DLT) is defined as acute grade 3 liver or intestinal toxicity or any acute grade 4 toxicity. If one patient experienced a DLT at a particular dose level, the cohort should be expanded to 6 patients. The maximum tolerated dose (MTD) is defined as the dose level below that which results in DLT in 2 or more of the 6 patients in each cohort. At least 5 patients should be enrolled in the cohort of 6 Gy x 5 even if none of the first 3 experienced DLT, as a means of added verification of dose tolerance, at this upper limit of dose for this study.

The patient population includes any patients who have unresectable hilar cholangiocarcinoma without any prior history of radiation. We anticipate accruing 1 patient every 2 months; therefore, we estimate that it will require approximately 22 months to accrue 11 patients if no DLT is experienced by any patients requiring expansion of the cohorts.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing External beam radiation and Cyberknife radiosurgery boost and capecitabine in people with Cholangiocarcinoma and Klatskin Tumor, run by University of California, San Francisco at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 22 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 11 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: investigator left UCSF and study was closed prematurely in 2008. No results to report.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To evaluate acute toxicities (time frame: 3 months for acute toxicities). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2015.
