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

  • Histologically- or cytologically-confirmed diagnosis of advanced carcinoma of the pancreas (stage IV disease only).
  • Patients whose tumor has progressed on gemcitabine or on a gemcitabine-containing combination. Patients must have received no more than two prior regimens for metastatic disease. Use of gemcitabine as a radiation sensitizer in combination with radiotherapy for localized disease will not be considered a prior gemcitabine-containing regimen if gemcitabine was received for ≤ 1 month following completion of radiotherapy. In addition, the use of 5-fluorouracil as a radiation sensitizer for localized disease will be allowed and not counted as a prior regimen if the 5-FU was continued for ≤ 1month following completion of radiotherapy.
  • Karnofsky Performance Status of ≥ 70%.
  • Patients must have discontinued previous anti-cancer therapy or other investigational agent at least three weeks or within 5 half lives of the drug (whichever is shorter) prior to entry into the study (six weeks for mitomycin C or nitrosureas) provided that all toxicities from prior treatment have resolved to a Grade 1 or less.
  • Patients must have discontinued radiation therapy at least two weeks prior to entry into the study and have recovered from all radiation-related toxicities.
  • Adequate organ function including the following:
Show all 12Show fewer
  • ANC ≥ 1500 cells/microL; platelets > 100,000/microL; hemoglobin ≥ 9 g/dL (may be transfused to this level).
  • Bilirubin ≤ 2.0 mg/dL; aspartate transaminase (AST/SGOT) and alanine transaminase (ALT/SGPT) ≤ 3.0 times institutional upper limit of normal (ULN) OR < 5 times institutional ULN if the subject has documented liver metastases.
  • Creatinine ≤2.0 mg/dL.
  • CA19-9 level >2 times ULN.
  • Disease that is measurable by CT scan per RECIST criteria (Appendix IV).
  • PET/CT or PET scan with SUV of ≥ 5.0 in at least one lesion on an 18F FDG scan.

Who cannot join

  • Active infection requiring antibiotics at study entry.
  • Any serious concomitant systemic disorder that in the opinion of the investigator would place the patient at excessive or unacceptable risk of toxicity.
  • Patients with active (requiring continuous medical therapy) pulmonary disease (COPD, asthma) or evidence of interstitial pneumonitis or pulmonary fibrosis on baseline chest X-ray or PET/CT scan.
  • Significant central nervous system or psychiatric disorder(s) that preclude the ability of the patient to provide informed consent.
  • Known or suspected brain metastases that have not received adequate therapy. Patients must be stable without requirement for steroids or seizure medications.
  • Major surgery within 4 weeks of study entry.
  • Chemotherapy/investigational drugs within 3 weeks or within 5 half lives of the drug (whichever is shorter) of study entry, provided that all toxicities from prior treatment have resolved to a Grade 1 or less.
  • Inability to tolerate prophylactic (1 mg/day) coumadin.

About this study

Official title: A Randomized Phase II Open-Label Study of Two Different Dose Levels of PX-12 in Patients With Advanced Carcinoma of the Pancreas Whose Tumors Have Progressed on Gemcitabine or on a Gemcitabine-Containing Combination

This study is being conducted to evaluate the clinical efficacy, biologic activity (inhibition of PX-12 target thioredoxin-1) and effects of an expired metabolite of PX-12 in patients with advanced pancreatic cancer.

Read the detailed description

In a Phase I trial, PX-12 demonstrated anti-tumor activity and pharmacodynamic activity across a wide dose range. At higher doses, one side effect of the agent was a garlic-like odor of an expired metabolite. This study is being conducted to evaluate the clinical efficacy, biologic activity (inhibition of PX-12 target thioredoxin-1) and effects of the expired metabolite at two dose levels of PX-12. This study will determine if the efficacy and biologic activity achieved at either of the two dose levels is sufficient to proceed to further studies without pushing to the maximally tolerated dose.

What is being measured

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

  1. Progression free survival and overall survival (percentage of patients alive at 6 months)

    Measured: 6 months

  2. Determine if there is a difference in effect on circulating Trx-1 protein levels between two dose levels of PX-12

    Measured: 21 days

Secondary outcomes (4)
  1. Determine which of two dose levels of PX-12 causes the greatest effect on three surrogate markers of clinical activity

    Measured: 42 days

  2. Determine effects of two different dose levels on overall clinical response

    Measured: 42 days

  3. Further evaluate safety profile of PX-12

    Measured: 21 days

  4. Assess the effects of metabolic excretion of PX-12

    Measured: 3 hours

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PX-12 in people with Pancreatic Neoplasms, run by Cascadian Therapeutics Inc. at 3 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 12 inclusion and 8 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 16 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 decision). 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?

Progression free survival and overall survival (percentage of patients alive at 6 months) (time frame: 6 months). 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 16 May 2018.
