  • History of allergic reactions to therapeutic antisense oligonucleotides
Show all 10Show fewer
  • Active autoimmune disease requiring treatment

About this study

Official title: The Pacific Clinical Trial: A Randomized Phase II Study Evaluating OGX-427 in Patients With Metastatic Castrate-Resistant Prostate Cancer (MCRPC)Who Have Prostate-Specific Antigen (PSA) Progression While Receiving Abiraterone: Hoosier Oncology Group GU12-159

This Phase II study has been designed to evaluate the anti-tumor effects of adding OGX-427 to continuing abiraterone acetate and prednisone treatment in men with metastatic castrate-resistant prostate cancer (MCRPC) who have prostate-specific antigen (PSA) progression

Read the detailed description

OUTLINE: This is a multi-center study.

This is an open-label, randomized, Phase II clinical trial designed to evaluate the anti-tumor effects of OGX-427 and continuing abiraterone acetate and prednisone versus continuing abiraterone acetate and prednisone alone in men with MCRPC who have evidence of PSA progression but no evidence of symptomatic or radiographic progression that would require alternative therapy (e.g., needing radiation therapy for pain or significant progression of visceral metastases).

Patients on the control arm will be allowed to cross-over to receive OGX-427 following documented disease progression. Patients will be randomized with equal probability to one of the following arms:

EXPERIMENTAL ARM (Arm A):

OGX-427 Starting within 7 days of randomization, three loading doses of 600 mg intravenously (IV) within Week 1 if possible (up to 10 days of initiating treatment), followed by weekly doses of 800 mg IV

Continuation of standard therapy with abiraterone acetate 1000 mg by mouth (PO) daily and prednisone 10-20 mg PO daily

CONTROL ARM (Arm B):

Continuation of standard therapy with abiraterone acetate 1000 mg PO daily and prednisone 10-20 mg PO daily

After documented disease progression, patients on Arm B may opt to receive OGX-427 treatment (according to the Arm A schedule) following a screening evaluation (i.e., all inclusion and exclusion criteria have been met)

Both Arms:

Evaluations at 4 week-intervals. Disease assessments required at the milestone Day 60 assessment (expected to occur after 8 weeks of treatment and prior to Day 1, Week 9) and at 16, 24, 32, 40, and 48 weeks (if applicable) or until documented disease progression. Patients who are withdrawn from the study for a reason other than documented disease progression or patient withdrawal of consent will be followed every 4 weeks in the Off-Treatment Follow-up Period until documented disease progression.

Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

Life Expectancy: Not Specified

Hematopoietic:

  • Absolute neutrophil count (ANC) ≥ 1.5 x 109 cells /L, platelet count ≥ 100 x 109 /L, and hemoglobin ≥ 9 g/dL without transfusion

Hepatic:

  • Total bilirubin ≤ 1.1 x upper limit of normal (ULN) unless elevated secondary to conditions such as Gilbert's disease, in which case a direct bilirubin ≤ ULN is required
  • Serum glutamic pyruvic transaminase (SGPT), alanine transaminase (ALT) and alanine transaminase (SGOT) aspartate transaminase (AST) ≤ 3.0 x ULN

Renal:

  • Creatinine ≤ 1.3 x ULN

Cardiac:

  • Known left ventricular ejection fraction (LVEF) <50% or New York Heart Association (NYHA) Functional Classification Class III or IV heart failure

Other:

  • Castrate serum testosterone level (< 50 ng/dL or < 1.7 nmol/L)
  • Potassium within normal limits

What is being measured

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

  1. Progression-Free Survival

    To ascertain whether Arm A has a greater proportion of patients observed to be alive without progression at Day 60 (±7 days) as compared to Arm B.

    Measured: 60 days

Secondary outcomes (1)
  1. PSA Response

    Compare arms to determine the proportion of patients who have a PSA response (≥ 30% decline) and any PSA decline post-randomization.

    Measured: 60 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing OGX-427, Abiraterone Acetate and Prednisone in people with Prostate Cancer and Metastatic Castrate-Resistant Prostate Cancer, run by Costantine Albany at 16 sites in 2 countries.

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 17 inclusion and 10 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 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in United States, Canada. 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?

Yes. Results are posted in the registry (first posted 18 Oct 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 (time frame: 60 days). 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 NCT01681433, 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 11 Jul 2022.
