About this study
Official title: A Phase I Study of Triapine® in Combination With Radiation Therapy in Locally Advanced Pancreas Cancer
This phase I trial is studying the side effects and best dose of 3-AP when given together with radiation therapy in treating patients with stage III pancreatic cancer that cannot be removed by surgery.
3-AP may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. 3-AP may make tumor cells more sensitive to radiation therapy. Giving 3-AP together with radiation therapy may kill more tumor cells.
Read the detailed description
PRIMARY OBJECTIVES:
- To determine the maximal tolerable dose (MTD) of 3-AP administered in combination with radiation therapy (XRT) in patients with locally advanced pancreatic carcinomas.
SECONDARY OBJECTIVES:
- To document the therapeutic response of this combination in patients with locally advanced pancreatic carcinomas.
II. To establish radiographic correlates using secretin stimulated magnetic resonance cholangiopancreatography (MRCP) and dynamic contrast enhanced magnetic resonance imaging (MRI).
III. To measure deoxycytidine triphosphate (dCTP) levels in peripheral blood mononuclear cells (PBMCs)before and after treatment at specified times and try to correlate findings to activity and toxicity of triapine.
OUTLINE: This is a dose-escalation study of 3-AP (Triapine®). Patients undergo radiotherapy once daily, 5 days a week, for approximately 5½ weeks (a total of 28 fractions).
Patients also receive 3-AP (Triapine®) IV over 2 hours 3 days a week every other week for 5½ weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of 3-AP (Triapine®) until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. At least 6 patients are treated at the MTD. After completion of study treatment, patients are followed monthly for 1 year.

Receives: Radiation: 3-Dimensional Conformal Radiation Therapy; Drug: Triapine |
What is being measured
The primary outcome is the main question the study is designed to answer.
MTD as assessed by the number of patients with dose-limiting toxicity (DLT)
MTD will be the dose at which 1 or fewer patients (less than or equal to 1/6) experiences a DLT during the treatment cycle with the next higher dose having at least 2/3 or 2/6 patients experiencing DLT. DLT will be defined as greater than or equal to Grade 3 non-hematologic or greater than or equal to Grade 4 hematologic adverse event with the following exceptions: greater than or equal to Grade 3 nausea and greater than or equal to Grade 3 vomiting that improves with antiemetic therapy greater than or equal to Grade 3 diarrhea that improves with Lomotil.
Measured: Observed clinically for 3-4 hours after each 3-AP infusion during the first week of treatment
Secondary outcomes (3)
Levels of dCTP in PBMCs correlated to activity and toxicity of 3-AP
The effect of 3-AP on dCTP levels in PBMCs will be evaluated using either a paired t-test or its nonparametric equivalent, the Wilcoxon matched pairs signed ranks test. Assuming normality, a paired t-test will allow us to detect an effect size of approximately 1.0 or greater in a sample of 12 patients with a two-sided alpha of 0.05 and a power of 0.88. All patients in a cohort will undergo the full 5 ½ weeks of therapy for toxicity assessment. NCI Common Toxicity Criteria version 4.0 will be used to grade toxicity.
Measured: Immediately before and after 3-AP on the first and last day of treatment
Radiographic correlates using secretin-stimulated MRCP and dynamic contrast enhanced MRI
The subjects will be imaged with conventional T2- and T1-weighted sequences prior to contrast agent application and with T1-weighted sequences after contrast agent application for tumor localization and volumetry. Dynamic contrast enhanced (DCE) images will be acquired to demonstrate tumor heterogeneity, microcirculation, vascularization and viability. Secretin-stimulated images will be acquired to quantify the functional status of the pancreas. The results will be purely descriptive.
Measured: Prior to treatment (baseline), 2 weeks within and 4 weeks after combined-modality therapy
Therapeutic response as assessed using the Response Evaluation Criteria in Solid Tumors (RECIST)
Complete Response (CR) is the disappearance of all target lesions. Partial Response (PR) requires at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. The results will be purely descriptive.
Measured: CT scans at baseline and 4 weeks from end of therapy and then every 2 months for 1 year from start of therapy. Confirmatory scans will also be obtained 2 months following initial documentation of an objective response.

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 21 inclusion and 0 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: finished, as of the sponsor's last update on 18 Aug 2017. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
MTD as assessed by the number of patients with dose-limiting toxicity (DLT) (time frame: Observed clinically for 3-4 hours after each 3-AP infusion during the first week of treatment). 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 18 Aug 2017.
