What participants receive

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

  • NeoTCR-P1 adoptive cell therapyBiological

    The investigational agent in this protocol is NeoTCR P1, an autologous adoptive T cell therapy (ACT) for patients with solid cancer. NeoTCR P1 is composed of apheresis derived CD8 and CD4 T cells that are precision genome engineered to express one autologous TCR of native sequence that targets a neoepitope (neoE) presented by human leukocyte antigen (HLA) receptors exclusively on the surface of that patient's tumor cells and not on other cells in the body.

  • nivolumabBiological

    Also called Opdivo

    Nivolumab is a human IgG4 anti-PD-1 monoclonal antibody

  • IL-2Biological

    Also called Proleukin, aldesleukin, interleukin-2

    IL-2 is a biologic response modifier. It is a type of protein called a cytokine.

What is being measured

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

  1. Incidence of adverse events as defined as DLTs

    Dose limiting toxicity (DLT) is defined as protocol-defined adverse events that occur within 28 days following infusion of Neo-TCR-P1 administered as a single agent without or with IL-2, or in combination with nivolumab.

    Measured: 28 days

  2. Number of participants with adverse events as a measure of safety and tolerability of NeoTCR-P1 or NeoTCR-P1 in combination with nivolumab

    Toxicity will be classified and graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, version 5.0). Cytokine release syndrome (CRS) and neurotoxicity associated with NeoTCR-P1 will be graded according to ASBMT consensus grading.

    Measured: 2 years

  3. Maximum Tolerated Dose (MTD) of NeoTCR-P1

    The MTD is defined as the highest dose with an observed incidence of DLT in no more than one out of six patients treated at a particular dose level.

    Measured: 2 years

  4. Feasibility of manufacturing NeoTCR-P1

    Percent of screened patients that enroll on study and receive NeoTCR-P1

    Measured: 2 years

Secondary outcomes (7)

  1. Maximum concentration of NeoTCR-P1 (Cmax) in the peripheral blood

    Measured: 2 years

  2. Area-under-the-concentration-vs-time-curve (AUC) in the peripheral blood

    Measured: 28 days

  3. Persistence of NeoTCR-P1 in samples of peripheral blood

    Measured: 2 years

  4. Objective Response Rate (ORR) in participants with solid tumors following infusion of NeoTCR-P1 as a single agent or in combination with nivolumab

    ORR will be defined as Complete Response (CR) or Partial Response (PR) per RECIST v1.1, as determined by the investigator

    Measured: 2 years

  5. Duration of Response mediated by neoTCR-P1 administered as a single agent or in combination with nivolumab to participants with solid tumors

    Duration of response, defined as time from the first occurrence of a documented objective response to the time of relapse or death from any cause

    Measured: 2 years

  6. Progression free survival (PFS) in participants with solid tumors following infusion of NeoTCR-P1 as a single agent or in combination with nivolumab

    PFS is defined from date of administration of NeoTCR-P1 cell infusion to the date of disease progression per the RECIST v1.1 or death as a result of any cause. Subjects who do not meet criteria for progression by the analysis data cut-off date will be censored at their last evaluable disease assessment date

    Measured: 2 years

  7. Overall survival (OS) in participants with solid tumors following infusion of NeoTCR-P1 as a single agent or in combination with nivolumab

    OS will be measured from the date of administration of NeoTCR-P1 to the date of death. Subjects who have not died by the analysis data cut-off date will be censored at their last date of contact.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing NeoTCR-P1 adoptive cell therapy, nivolumab and IL-2 in people with Solid Tumor, run by PACT Pharma, Inc. at 9 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 7 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: paused, as of the sponsor's last update on 18 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 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?

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?

Incidence of adverse events as defined as DLTs (time frame: 28 days). 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?

On the ClinicalTrials.gov record for NCT03970382, which also lists 2 linked publications.

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 18 Aug 2022.
