About this study

Official title: An Open Label Phase II Study to Evaluate the Safety and Efficacy of Ipatasertib (GDC-0068) in Combination With Paclitaxel in Platinum-resistant Recurrent Epithelial Ovarian Cancer

This is a phase II open label, non-randomized, study to evaluate the safety and efficacy of Ipatasertib (GDC-0068) in combination with paclitaxel in platinum-resistant recurrent epithelial ovarian cancer.

Read the detailed description

This is a phase II open label, non-randomized, study to evaluate the safety and efficacy of Ipatasertib (GDC-0068) in combination with paclitaxel in platinum-resistant recurrent epithelial ovarian cancer.

The primary objective of the study is to determine - the safety and objective response rate of treatment with ipatasertib (GDC-0068) in combination with paclitaxel in platinum-resistant recurrent epithelial ovarian cancer at week 12 for two cohorts of patients: with PI3K/AKT mutations (altered) and without PI3K/AKT mutations (non-altered)

About 39 patients will participate in the study and the accrual will take place over a course of 30 months Patients will be treated until disease progression and followed for 1 year thereafter.

The two drugs are ipatasertib and paclitaxel.

  • Ipatasertib will be given 400mg PO daily: day 1-21 of 28 day cycle
  • Paclitaxel will be given 80mg/m2 IV weekly: day 1, 8, 15 of 28 day cycle

The study hypothesis is that the combination of Ipatasertib (GDC-0068) plus paclitaxel will safely induce a tumor response and increase the objective response rate in patients with platinum-resistant recurrent epithelial ovarian cancer, with or without PI3K/AKT mutations.

This trial will enroll patients with platinum-resistant recurrent epithelial ovarian cancer. Given the relatively poor prognosis and limited treatment options for these patients, this population is considered appropriate for trials of novel therapeutic candidates. The benefit-risk ratio for ipatasertib in combination with paclitaxel is expected to be acceptable in this setting.

What is being measured

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

  1. Objective response rate (ORR)

    ORR will be measured by the percentage of patients whose cancer decreases in size on assessment. This will be measured as the sum of complete response and partial response.

    Measured: At the end of Cycle 1 (each cycle is 28 days)

  2. Objective response rate (ORR)

    ORR will be measured by the percentage of patients whose cancer decreases in size on assessment. This will be measured as the sum of complete response and partial response.

    Measured: At the end of Cycle 2 (each cycle is 28 days)

  3. Objective response rate (ORR)

    ORR will be measured by the percentage of patients whose cancer decreases in size on assessment. This will be measured as the sum of complete response and partial response.

    Measured: At the end of Cycle 3 (each cycle is 28 days)

Secondary outcomes (4)
  1. Progression free survival (PFS)

    Disease status will be assessed with comprehensive radiographic studies every 3 treatment cycles (12 weeks +/- 1 week), but the development of new signs or symptoms of disease in between scheduled evaluations may prompt off-schedule radiographic or non-radiographic evaluations. Disease status will be assessed based on RECIST 1.1 criteria for measurable and non-measurable disease.

    Measured: At the end of Cycle 1 (each cycle is 28 days)

  2. Progression free survival (PFS)

    Disease status will be assessed with comprehensive radiographic studies every 3 treatment cycles (12 weeks +/- 1 week), but the development of new signs or symptoms of disease in between scheduled evaluations may prompt off-schedule radiographic or non-radiographic evaluations. Disease status will be assessed based on RECIST 1.1 criteria for measurable and non-measurable disease.

    Measured: At the end of Cycle 2 (each cycle is 28 days)

  3. Progression free survival (PFS)

    Disease status will be assessed with comprehensive radiographic studies every 3 treatment cycles (12 weeks +/- 1 week), but the development of new signs or symptoms of disease in between scheduled evaluations may prompt off-schedule radiographic or non-radiographic evaluations. Disease status will be assessed based on RECIST 1.1 criteria for measurable and non-measurable disease.

    Measured: At the end of Cycle 3 (each cycle is 28 days)

  4. Disease control rate (DCR)

    DCR will be measured by the percentage of patients whose cancer decreases in size or remains stable over the duration of the study. This will be measured as the sum of complete response, partial response, and stable disease for greater than or equal to 24 weeks.

    Measured: average 24 weeks

Model description
For non-altered patients- An interim analysis is scheduled when the number of enrolled patients reaches 14. The research team will stop the trial for futility if 2 or less than 2 patients respond. When the total number of patients reaches the maximum sample size of 25, the research team will reject the null hypothesis and conclude that the treatment is promising if the number of responses are greater than 6; otherwise the research team will conclude that the treatment is not promising. For altered patients-An interim analysis is scheduled when the number of enrolled patients reaches 8. The research team will stop the entire trial of two cohorts for futility if 1 or less than 1 patients respond. When the total number of patients reaches the maximum sample size of 14, the research team will reject the null hypothesis and conclude that the treatment is promising

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ipatasertib and Paclitaxel in people with Ovarian Neoplasms, run by Icahn School of Medicine at Mount Sinai 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 17 inclusion and 37 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: withdrawn, as of the sponsor's last update on 6 Oct 2020. 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 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 withdrawn before enrolling participants, so there are no results.

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?

Objective response rate (ORR) (time frame: At the end of Cycle 1 (each cycle is 28 days)). The study lists 3 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 6 Oct 2020.
