About this study

Official title: Intraperitoneal FATE FT516 and Interleukin-2 (IL-2) With Intravenous Enoblituzumab in Recurrent Ovarian, Fallopian Tube, and Primary Peritoneal Cancer

This is a single center Phase I clinical trial of FT516 administered intraperitoneally (IP) once a week for 3 consecutive weeks for the treatment of recurrent gynecologic cancers. As this is an early 1st in human study and the 1st intraperitoneal infusion of FT516, the safety of FT516 is confirmed prior to adding enoblituzumab as an intravenous infusion approximately 1 week prior to the 1st dose of FT516 and every 3 weeks beginning on Day 22 (1 week after the last dose of FT516). Each dose of FT516 is followed directly by an IP infusion of interleukin-2 (IL-2) to facilitate natural killer (NK) cell survival. A short course of outpatient lymphodepletion chemotherapy is given prior to the 1st dose of FT516.

Read the detailed description

FT516 is an off the shelf product comprised of allogeneic natural killer (NK) cells, expressing high-affinity non-cleavable CD16 (FT516). Enoblituzumab is an Fc-optimized monoclonal antibody that targets B7-H3 which is highly expressed on ovarian cancer. Based on data showing that within the ovarian cancer tumor microenvironment surface expression of CD16a on NK cells is diminished, the researchers hypothesize that the FT516 cellular product containing a non-cleavable CD16 will bypass the low CD16 expression issue and maximize NK cell cytotoxicity. Enoblituzumab is an Fc optimized humanized IgG1 monoclonal antibody that binds to B7-H3 (CD276). B7-H3 is an inhibitory immune checkpoint molecule that is widely expressed by a number of different tumor types and may play a key role in regulating the immune response. It is therefore hypothesized that the combination of FT516 with enoblituzumab will maximize NK cell cytotoxicity in patients with ovarian cancer.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • IP FT516Drug

    FT516 is an off-the-shelf cryopreserved NK cell product derived from an iPSC that was transduced with a high affinity, ADAM17 non-cleavable CD16 (Fc receptor) that maintains CD16 on the cell surface, which remains fully functional after NK cell activation

  • EnoblituzumabDrug

    Enoblituzumab is an Fc-optimized monoclonal antibody that targets B7-H3 which is highly expressed on ovarian cancer. Enoblituzumab at 15 mg/kg IV, one day before lymphodepleting chemotherapy

  • IL-2Drug

    Also called Interleukin-2

    IL-2 at 6 Million IU (3 Million IU/m2 if patient weight is <45 kg) is administered IP in 50 cc of room temperature D5W via peritoneal catheter directly after the FT-516 infusion is completed. Immediately following the IL-2, an additional 100 cc D5W flush is infused into the peritoneal cavity through the peritoneal catheter as rapidly as possible.

    Measured: 28 Days Post FT516 infusion

  2. Number of Participants Experiencing Adverse Events

    Number of participants experiencing adverse events related to FT516

    Measured: 28 days after first dose of FT516 or 28 days after last dose of Enoblituzumab (arm 4 and 5 only)

Secondary outcomes (4)
  1. Number of Participants Experiencing Progression Free Survival

    Number of participants experiencing progression free survival at 6 months from the first dose of FT516

    Measured: 6 months from the first dose of FT516

  2. Number of Participants Experiencing Progression Free Survival

    Number of participants experiencing progression free survival at 1 year from the first dose of FT516

    Measured: 1 year from the first dose of FT516

  3. Number of Participants Experiencing Overall Survival

    Number of participants experiencing overall survival at 6 months from the first dose of FT516

    Measured: 6 months from the first dose of FT516

  4. Number of Participants Experiencing Overall Survival

    Number of participants experiencing overall survival at 1 year from the first dose of FT516

Model description
This study is conducted in two consecutive stages with 5 cohorts. A minimum of 28 days must separate each cohort. Within a 3 patient cohort, a minimum of 14 days must separate the first and second patient. Stage 1 Step 1 uses a fast-track design (1 patient per cohort) with a minimum of 28 days between each patient until one of the following: a) 1st occurrence of a pre-defined adverse event at which point the study moves to Step 2. The cohort size increases from 1 to 3 patients with 2 additional patients added. Escalation in Step 2 continues until the 1st DLT at which point Stage 2 continual reassessment method (CRM) is activated. If Cohort 5 is completed with 10 patients enrolled at the MTD without a DLT, Stage 2 (CRM) is not used. b) The 1st occurrence of a DLT the study moves directly to Stage 2 (CRM) and Step 2 is not used. c) Cohort 5 is completed without a pre-defined AE or a DLT - neither Step 2 nor Stage 2 is used if a total of 10 patients are enrolled in Cohort 5.

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 18 inclusion and 11 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 3 Apr 2023. 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 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?

Yes. Results are posted in the registry (first posted 3 Apr 2023). 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?

Number of Participants Experiencing Dose Limiting Toxicity (DLT) Events (time frame: 28 Days Post FT516 infusion). The study lists 2 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 3 Apr 2023.
