About this study

Official title: Prospective Phase Ib Clinical Trial to Evaluate the Safety and Efficacy of Oregovomab and Hiltonol® as a Combinatorial Immunotherapy Strategy in Patients With Recurrent Advanced Epithelial Cancer of Ovarian, Tubal, or Peritoneal Origin

This is a Phase Ib study to look at the combination of an antibody immunization vaccine strategy using oregovomab and an investigational stage immune booster (poly ICLC / Hiltonol), both of which have previously been used in combination with other cancer treatments and demonstrated to be active in advanced cancer, but which have not previously been used together. This study will assess the approach as to whether these two drugs can safely add to the response seen with either drug alone, both of which have doses that are based on prior studies.

Subjects with stable disease for whom a 12 week break from therapy for their persistent and progressive advanced ovarian cancer is appropriate, who have signed informed consent and for whom baseline clinical information is completed, will receive 4 cycles of oregovomab/Hiltonol immunization every three weeks (weeks 0, 3, 6, and 9). Blood will be obtained for to look for a CA125 specific T cell response at 12 weeks before initiating any additional therapy according to the best clinical judgment of the investigator. At week 16 the subjects will receive a final dose of the combination of oregovomab/Hiltonol and at week 17 will have an additional blood draw for analysis of T-cell response.

Read the detailed description

This is a Phase Ib evaluation of the combination of an antibody immunization vaccine strategy using oregovomab and an investigational stage immune adjuvant (poly ICLC / Hiltonol), both of which have previously been used in combination with other cancer treatments and demonstrated to be bioactive in advanced cancer, but which have not previously been combined together. The doses selected for each agent have been selected previously through human clinical study for use in immunization protocols as a well-tolerated and bioactive immune stimulatory dose. For immunization purposes a maximum tolerated dose is not a relevant pharmacologic objective. Rather this is an exercise in efficiently assessing a preliminary immunization protocol as a cost effective product development strategy assessing the ability of the combination to safely augment the immune signals measurable with either agent alone, both of which have been titrated to the current dose based on the principle of bell shaped dose response in immunization in prior studies.

Subjects with stable disease for whom a 12 week break from cytotoxic therapy for their persistent and progressive advanced ovarian cancer is appropriate, who have signed informed consent and for whom baseline clinical information including laboratory, radiologic and physical documentation of their status is completed, will receive 4 cycles of oregovomab/Hiltonol immunization every three weeks (weeks 0, 3, 6, and 9). Blood will be obtained for the measurement of CA125 specific T cell immunity at 12 weeks before initiating continuing salvage therapy according to the best clinical judgment of the investigator. At week 16 the subjects will receive a final immunization with oregovomab/Hiltonol and at week 17 an additional blood draw for analysis of T-cell immunity.

What is being measured

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

  1. Change in laboratory values, physical findings (physical examination), vital signs, subjective patient experience and treatment-related adverse events as assessed by CTCAE v4.0

    The primary outcome is to establish the preliminary safety regarding the combination of the anti-CA-125 monoclonal antibody oregovomab and the TLR3 agonist immune adjuvant poly ICLC (Hiltonol ®) as a strategy to induce CA125 specific anti-tumor immunity in heavily pretreated subjects with progressive ovarian cancer.

    Measured: Week 0 to Week17+30 days

Secondary outcomes (3)
  1. Evaluation of cellular immune response to oregovomab.

    Evaluation of the cellular immune response to oregovomab by a CA125 specific cellular immune response assay

    Measured: Week 0, Week 12, Week 17

  2. Evaluation of human anti-mouse antibody (HAMA) response to oregovomab.

    Evaluation of HAMA response to oregovomab by a commercial HAMA assay.

    Measured: Week 0, Week 12, Week 17

  3. Time to overall survival

    Evaluation of overall survival up to three years after study completion.

    Measured: Up to Week 173

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Oregovomab and Poly ICLC in people with Cancer of Ovary and Neoplasms, Ovarian, run by CanariaBio Inc. at 2 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 15 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 22 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 was stopped early (reason given: Sponsor Decision to discontinue long-term follow-up). 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?

Change in laboratory values, physical findings (physical examination), vital signs, subjective patient experience and treatment-related adverse events as assessed by CTCAE v4.0 (time frame: Week 0 to Week17+30 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 NCT03162562, 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 22 Dec 2020.
