About this study

Official title: Phase Ib Multicenter, Cohort Dose Escalation Trial to Determine the Safety, Tolerance and Preliminary Antineoplastic Activity of Gemcitabine Administered in Combination With Continuous Intravenous Doses of PRI-724, a CBP/ β- Catenin Inhibitor, to Patients With Advanced or Metastatic Pancreatic Adenocarcinoma Eligible for Second-Line Therapy After Failing First-Line Therapy With FOLFIRINOX (or FOLFOX)

Laboratory studies suggest that the study drug may stop cancer cells from growing by affecting an interaction between proteins in the cells referred to as cAMP-response element-binding protein and ß-catenin.

The purpose of this research study is to determine the highest safe dose of study drug that may be used when it is given together with a chemotherapy drug to patients with cancer of the pancreas.

Read the detailed description

PRI-724 is a small molecule antagonist that binds to the co-activator CBP thereby specifically inhibiting the subset of Wnt/β-catenin-driven genes that are up-regulated in cancer cells. PRI-724 is being developed as a potential antineoplastic agent.

Purpose:

To determine the safety, tolerability, dose-limiting toxicities (DLTs), and maximum tolerated dose (MTD) of sequential escalating doses per cohort of PRI-724 administered in combination with gemcitabine to patients with adenocarcinoma of the pancreas that is locally advanced, metastatic, or otherwise inoperable, who are candidates for second-line therapy after failing first-line therapy with FOLFIRINOX (i.e., folinic acid [leucovorin], fluorouracil, irinotecan, oxaliplatin)

  • PRI-724: 320, 640, 905 mg/m2/day, continuous intravenous (CIV) infusion over 24 h, daily × 7 days, 1 week on with 1 week recovery × 2 (4 weeks equals 1 cycle)
  • Gemcitabine: 1000 mg/m2 IV over 30 minutes; 3 weeks on with 1 week recovery (4 weeks equals 1 cycle)

Patients with documented, measurable or evaluable adenocarcinoma of the pancreas that is locally advanced, metastatic, or otherwise inoperable, who are candidates for second-line therapy after failing first-line therapy with FOLFIRINOX, will be entered into this phase 1b, multicenter, open-label, non-randomized, dose-escalation per cohort study. The trial is designed to evaluate the safety, tolerability, DLT(s), and MTD of escalating doses of PRI-724, a CBP/ β- catenin inhibitor, when administered in combination with a standard dose of gemcitabine. Correlative studies include characterization of the PK profiles of PRI-724 and gemcitabine, evaluation of the utility of potential PD markers of PRI-724 activity, as well as preliminary assessment of the antineoplastic activity of PRI-724 plus gemcitabine in this patient population.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Maximum Tolerated Dose (MTD) of PRI-724 + Gemcitabine measured by the number of dose limiting toxicities (DLTs) that occur.

    If no DLT occurs in the first 3 patients of a cohort, the dose will be escalated to the next dose cohort. If 1 DLT occurs in the first 3 patients of a cohort, that cohort is expanded to 6 patients. If more than 1 DLT occurs in a 6 patient cohort, escalation is stopped \& next lower dose is expanded to 12 patients to confirm the MTD.

    Measured: 18 months. DLTs will be measured as they occur throughout the patients' time on study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PRI-724 in people with Advanced Pancreatic Cancer and Metastatic Pancreatic Cancer, run by Prism Pharma Co., Ltd. at 5 sites 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 8 inclusion and 36 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 17 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 5 sites 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?

The Maximum Tolerated Dose (MTD) of PRI-724 + Gemcitabine measured by the number of dose limiting toxicities (DLTs) that occur. (time frame: 18 months. DLTs will be measured as they occur throughout the patients' time on study.). 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 17 Aug 2017; AzTrials last refreshed its copy on 7 Nov 2026.
