About this study

Official title: A PHASE II TRIAL OF Hu3S193 THERAPY FOR PATIENTS WITH PLATINUM REFRACTORY OR PLATINUM RESISTANT EPITHELIAL OVARIAN, PRIMARY PERITONEAL AND FALLOPIAN TUBE CANCER

RATIONALE: Monoclonal antibodies, such as Hu3S193, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.

PURPOSE: This phase II trial is studying how well Hu3S193 works in treating patients with ovarian epithelial cancer, fallopian tube cancer, or peritoneal cavity cancer.

Read the detailed description

OBJECTIVES:

Primary

  • To evaluate the efficacy of monoclonal antibody Hu3S193 in women with platinum-resistant/refractory ovarian, fallopian tube, or primary peritoneal cancer, based on RECIST criteria (Response Evaluation Criteria in Solid Tumors).

Secondary

  • To determine the safety of the study drug.
  • To determine the drug pharmacokinetics when administered in multiple weekly injections.

Exploratory analysis

  • Clinical Benefit (objective response rate + tumor stabilization).
  • Progression Free Survival (PFS).
  • Duration of Response.
  • Overall Survival.
  • 12-month survival rate.

OUTLINE: This is a multicenter study.

Patients receive monoclonal antibody Hu3S193 IV over 1 hour once weekly in weeks 1-8. Treatment repeats every 8 weeks for up to 3 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed monthly.

What is being measured

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

  1. Best Overall Response

    Best response recorded from the start of treatment until disease progression/recurrence. Includes all patients evaluable for efficacy, regardless of used criteria: RECIST or CA-125 (Cancer Antigen 125).

    Evaluation of target lesions: Complete Response (CR), resolution of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter (LD sum) of target lesions, taking as reference the baseline LD sum; Progressive Disease (PD), a 20% increase in LD sum of target lesions or the appearance of new lesion(s); Stable Disease (SD), no sufficient shrinkage to qualify as PR nor sufficient increase to qualify as PD. Evaluation of non-target lesions: CR, resolution of all non-target lesions and normalization of CA-125 level; SD, persistence of one or more non-target lesions and/or maintenance of CA-125 level above the normal limits; PD, appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions.

    Measured: From start of study treatment until the end of Cycle 1 (8 weeks), Cycle 2 (16 weeks) or Cycle 3 (24 weeks).

Secondary outcomes (4)

  1. Number of Participants With Adverse Events and Serious Adverse Events

    A listing of all adverse events is located in the Reported Adverse Event module.

    Measured: From the first dose of investigational product up to 30 days after the last dose of investigational product

  2. Number of Participants With Adverse Events Reasonably Related to the Investigational Product (Incidence Greater Than 5%).

    Adverse events with possible, probable or definite relationship to the investigational product were considered to be reasonably related.

    Measured: From the first dose of investigational product up to 30 days after the last dose of investigational product

  3. Mean Cmax and Cmin of Hu3S193 Relating to the First 4 Doses.

    Cmax = Peak (post-dosing) IP (Investigational Product) plasma concentration. Cmin = Trough (pre-dosing) IP plasma concentration (Cmin). Plasma concentration of Hu3S193 expressed in µg/mL.

    Measured: Pre-dose (within 10 minutes) and Post-dose (5 minutes after completion of infusion) on weeks 1, 2, 3, and 4 of Cycle 1.

  4. Mean Cmax and Cmin of Hu3S193 Relating to the First 8 Doses

    Cmax = Peak (post-dosing) IP plasma concentration. Cmin = Trough (pre-dosing) IP plasma concentration (Cmin). Plasma concentration of Hu3S193 expressed in µg/mL.

    Measured: Pre-dose (within 10 minutes) and Post-dose (5 minutes after completion of infusion) on weeks 1, 2, 3, 4, 5, 6, 7 and 8 of Cycle 1.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing hu3S193 in people with Fallopian Tube Cancer and Ovarian Cancer, run by Recepta Biopharma at 8 sites in Brazil.

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 11 inclusion and 21 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 26 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Brazil. 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 26 Nov 2013). 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?

Best Overall Response (time frame: From start of study treatment until the end of Cycle 1 (8 weeks), Cycle 2 (16 weeks) or Cycle 3 (24 weeks).). 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 NCT00617773, 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 26 Nov 2013; AzTrials last refreshed its copy on 8 Nov 2026.
