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

  • For the dose-escalation phase, patients must have cytologically or histologically proven advanced malignant solid tumors, with emphasis on CRPC.
  • Patients must be 18 years of age or older.
  • Patients must have a Zubrod (ECOG) performance status of 0-2.
  • Patients must have an estimated survival of at least 3 months.
  • Any prior chemotherapy must have been completed at least 4 weeks prior to start of treatment. Prior radiation must have been completed at least 2 weeks prior to start of therapy. Patients must have recovered from acute reversible side effects of prior chemotherapy regimens or radiotherapy to < grade 1 (excluding alopecia, lymphopenia, and hyperglycemia) according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 4.0.
  • Radiographs (Xrays, CT scans, etc) to follow disease response or progression must have been completed within 28 days prior to registration.

  • Patients must have adequate renal function as documented by a calculated creatinine clearance of > 45 ml/min (see Appendix for formula for calculating creatinine clearance).
  • Patients must have adequate liver functions: AST and ALT < 2.5 X upper limit of normal, and bilirubin < upper limit of normal.
  • All patients must have a histologic diagnosis of adenocarcinoma of the prostate which is measurable or non-measurable.
  • Patients must have metastatic prostate cancer deemed to be unresponsive or refractory to hormone therapy by one or more of the following (despite androgen deprivation and antiandrogen withdrawal when applicable):
  • Progression of measurable disease assessed within 28 days prior to registration.
  • Progression of non-measurable disease assessed within 28 days prior to registration.
  • Rising PSA - Rising PSA is defined as at least two consecutive rises in PSA to be documented over a reference value (measure 1). The first rising PSA (measure 2) must be taken at least 7 days after the reference value. A third confirmatory PSA measure is required (2nd beyond the reference level) to be greater than the second measure, and it must be obtained at least 7 days after the 2nd measure. If this is not the case, a fourth PSA is required to be taken and be greater than the second measure. The patient must have a PSA ≥ 5 ng/ml in addition to increasing PSA to be eligible by rising PSA criteria alone. However, no minimum PSA is required for patients whose progression is based on measurable or non-measurable disease.
  • All patients must have a pre-study PSA obtained within 28 days prior to registration.
  • All patients must have had imaging studies within 28 days prior to registration. The choice of imaging studies to follow disease will be at the discretion of the investigator.
  • Patients must be offered the opportunity to participate in specimen banking for future use (to include the serum and tissue correlative studies).
  • Patients must have been surgically or medically castrated. If method of castration is LHRH agonists (leuprolide or goserelin) or LHRH antagonists, then the patient should be willing to continue the use of LHRH agonists. Patients who have stopped treatment should be willing to restart.
  • If the patient has been treated with non-steroidal antiandrogens (flutamide, bicalutamide, nilutamide or ketoconazole), they must have been stopped at least 14 days prior to registration for ketoconazole and at least 28 days prior to registration for flutamide, bicalutamide or nilutamide and the patients must have demonstrated progression.
  • Prior, planned, or ongoing bisphosphonate therapy or denosumab is allowed.

Who cannot join

  • (Dose-Escalation Phase)
  • Pregnant or breastfeeding women. The effects of these drugs on the unborn fetus are unknown. Documentation of a negative serum pregnancy test is required for all women of reproductive potential.
  • Patient has a clinically significant concurrent illness. Patients must not have a serious intercurrent medical or psychiatric illness, including serious active infection.
  • Patient is currently enrolled in a different clinical study in which investigational procedures are performed or investigational therapies are administered. Also, a patient may not enroll in such clinical trials while participating in this study.
  • Patient has a history of allergy or hypersensitivity to the study drugs or a taxane.
  • Patient has serious medical risk factors involving any of the major organ systems such that the investigator considers it unsafe for the patient to receive an experimental research drug.

About this study

Official title: Phase 1 Trial of ADI PEG 20 Plus Docetaxel in Advanced Solid Tumors With Emphasis on Castration Resistant Prostate Cancer (CRPC) and Advanced Non-Small Cell Lung Cancer (NSCLC)

This Phase I trial combines ADI-PEG 20 with docetaxel in patients with advanced solid tumors with emphasis on castration resistant prostate cancer (CRPC). The investigators hypothesize that the combination will result in greater tumor cytotoxicity with an acceptable toxicity profile (i.e., manageable side effects) in cancer patients due to the unique mechanism of action of ADI-PEG 20. The investigators also hypothesize that the combination of ADI-PEG 20 and docetaxel will result in enhanced tumor cell apoptosis in part due to autophagy and that this will be particularly relevant in CRPC.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ADI-PEG 20 in people with Solid Tumors and Prostate Cancer, run by Polaris Group 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 19 inclusion and 14 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 13 Sep 2018. 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?

Number of Participants with Adverse Events (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?

On the ClinicalTrials.gov record for NCT01497925, which also lists 1 linked publication.

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 13 Sep 2018.
