About this study

Official title: Atezolizumab in Combination With Neoadjuvant Chemotherapy and Interval Cytoreductive Surgery for Patients With Newly-Diagnosed Advanced-Stage Epithelial Ovarian Cancer

The main purpose of this study is to validate a safe dose of atezolizumab with dose-dense paclitaxel and carboplatin when utilized with neoadjuvant chemotherapy and interval cytoreductive surgery followed by maintenance atezolizumab in women with advanced ovarian cancer.

Read the detailed description

This is a Phase IB non-randomized, single-arm, open-label study of atezolizumab in combination with primary NACT-ICS in patients with advanced-stage epithelial ovarian cancer. The target population is women with previously untreated epithelial ovarian cancer (including fallopian tube and primary peritoneal cancer) with advanced stage (FIGO III-IV) disease suitable for NACT and ICS. The following regimen will be administered every 3 weeks for 3 cycles prior to ICS, then for 3 cycles following ICS:

  • Carboplatin AUC = 5 or 6 IV, D1 of each cycle
  • Paclitaxel 70 to 80mg/m2 IV, over one hour, on D1, 8, 15 of each cycle
  • Atezolizumab 1200mg IV D1 of each cycle of chemotherapy and will be continued as maintenance therapy every 3 weeks until there is a lack of clinical benefit, unacceptable toxicity, or a total duration of 18 months.
  • Bevacizumab (15 mg/kg IV every 3 weeks) may be added at cycle 5 of chemotherapy as per FDA approval. Those who opt for bevacizumab will receive chemotherapy, atezolizumab, and bevacizumab for cycles 5 and 6 followed by atezolizumab and bevacizumab maintenance. Maintenance bevacizumab will be given for a total duration of 16 cycles. Patients who have completed chemotherapy may opt for bevacizumab in the maintenance setting only if the amendment to add bevacizumab was not approved before after they started maintenance therapy.
  • Upon completion of concurrent chemotherapy and atezolizumab therapy, patients will commence maintenance treatment with atezolizumab + bevacizumab for a total of up 16 cycles of maintenance therapy (22 total cycles of atezolizumab, and 18 total cycles of bevacizumab).

Each cycle is 21 days in duration and will be administered in the outpatient setting. Limited individualized flexibility in dose assignment (as noted) is permitted per physician discretion in regards to advanced-stage disease, nutritional status, ascites, non-physiologic creatinine measurements, and other comorbidities.

Three cycles of NACT with atezolizumab will be administered every 3 weeks prior to ICS (occurring between cycles 3 and 4) followed by 3 additional cycles (cycles 4-6) of chemotherapy with atezolizumab. Surgery must be performed after the third course of chemotherapy as soon as nadir counts permit, but preferably within six weeks after the completion of the third chemotherapy cycle. Fourth cycle of chemotherapy is to be administered as soon as possible, but preferably no more than six weeks after ICS.

Safety monitoring, including assessment for irAEs, will occur at each cycle and for 90 days after the last administration of atezolizumab or until start of next anti-cancer regimen, whichever occurs first. Image assessment by CT scan or MRI will be performed at baseline, prior to ICS to assess response, after completion of 6 cycles of chemotherapy with atezolizumab to assess response at end of chemotherapy treatment, and as clinically indicated during the maintenance phase and after completion of study treatment to assess PFS. Disease progression/recurrence will be defined per RECIST criteria and will not include isolated asymptomatic progression on the basis of CA125 levels. Immune function analysis will be performed on blood and tumor samples obtained at two time points: 1. confirmatory biopsy prior to start of therapy and 2. ICS.

It is estimated that 40 patients will be enrolled at an accrual rate of 3-5 patients/month and followed for a median of 3 years.

What is being measured

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

  1. Safety: Incidence of Post Chemotherapy Surgical Debulking

    The number of subjects able to undergo interval cytoreductive surgery will be utilized as a measure of safety regarding the initial dosing of atezolizumab.

    Measured: 9 weeks

  2. Safety: Incidence of Treatment Emergent Adverse Events

    The number of adverse events experienced while receiving study drugs will be utilized to assess safety of atezolizumab.

    Measured: 18 months

  3. Safety: Dose Intensity

    Percentage of planned doses of atezolizumab received at each cycle (21 day period) will be utilized as a measure of safety and tolerability for each subject.

    Measured: Cycles 1-6,18 months total

  4. Safety: Incidence of Dose Modifications

    The number of dose modifications for atezolizumab at each cycle (21 day period) will be utilized as a measure of safety and tolerability for each subject. Dose modifications are defined as doses delayed, doses discontinued, or doses held.

    Measured: Cycles 1-6,18 months total

Secondary outcomes (4)
  1. Number of Participants With a Complete or Partial Response as Measured by RECIST (Response Evaluation Criteria in Solid Tumors)

    RECIST criteria will be utilized for subjects over the course of the study to measure their response to study drugs. A Complete Response (disappearance of all tumor lesions) or Partial Response (reduction of greater than 30% in total tumor size) is considered a response.

    Measured: 18 months

  2. Number of Participants With Pathologic Complete Remission

    Cytoreduction pathologic complete remission will be measured using RECIST (Response Evaluation Criteria in Solid Tumors) and immune-related response criteria.

    Measured: 9 weeks

  3. Progression Free Survival Rate

    All patients will be evaluated for progression free survival from the date of first treatment to the date of first observation of progressive disease or death due to any cause or will be stopped at date of last follow-up for those still alive without disease progression. 18-month progression free survival rate as estimated by Kaplan-Meier method.

    Measured: 18 months

  4. Overall Survival Rate

    All patients will be evaluated for overall survival from the date of first treatment on protocol to the date of death due to any cause and will be stopped at date of last follow-up for those still alive.18-month overall survival rate as estimated by Kaplan-Meier method.

    Measured: 18 months

A Phase 1/2 study testing Atezolizumab, Carboplatin and Paclitaxel in people with Ovarian Cancer and Ovarian Neoplasms, run by Duke University at 3 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 13 inclusion and 25 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 12 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 combined 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.

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 10 Aug 2021). 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?

Safety: Incidence of Post Chemotherapy Surgical Debulking (time frame: 9 weeks). The study lists 4 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 12 Aug 2021.
