About this study

Official title: Phase Ib/II Study of Pembrolizumab With Lanreotide Depot for Gastroenteropancreatic Neuroendocrine Tumors

This study is for patients with non-resectable, recurrent, or metastatic well or moderately differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

The study will be conducted in two stages: 1) Safety Run-In and 2) Expanded Cohort.

  1. Safety run-in: The first stage will include a safety run-in of 6 patients treated with pembrolizumab 200 mg intravenous (IV) every 3 weeks and lanreotide depot 90mg subcutaneous (SQ) every 3 weeks. Up to 6 patients at the Duke Cancer Institute will be accrued at the starting dose level. If one or less subject meets treatment-related discontinuation criteria (as specified in the protocol) during Cycle 1, then the study will proceed to the second stage, Expanded Cohort.
  2. Expanded Cohort: Patients will be treated with pembrolizumab 200mg IV every 3 weeks and lanreotide depot 90mg SQ every 3 weeks as determined by the Safety Run-In Cohort.

What is being measured

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

  1. Objective Response Rate (ORR) as Measured by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)

    ORR is calculated as the number of people with a complete response (CR) or partial response (PR), divided by the total number of people treated. Complete response is defined as disappearance of all target lesions. Partial response is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. A lower limit of the true ORR will be estimated by the 90% exact lower confidence bound (LCB) for the binomial proportion. A 90% LCB of < 0.1 will be considered not to be of clinical value. If the 90% LCB is ≥ 0.1, the regimen will be considered efficacious.

    Measured: Approximately every 12 weeks until study completion (up to 2 years)

Secondary outcomes (4)

  1. Number of Participants Experiencing Treatment-related AEs Leading to Drug Discontinuations During the First 12 Weeks of Treatment

    Adverse events were graded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

    Measured: First 12 weeks of treatment

  2. Months of Progression-free Survival (PFS)

    Months from treatment start date until the date of first documented radiographic progression or date of death from any cause (whichever is first); assessed up to 48 weeks after the last subject has finished study drug regimen. Progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression.

    Measured: Up to 3 years

  3. Months of Overall Survival (OS)

    Months from treatment start date until the date of death from any cause; assessed up to 48 weeks after the last subject has finished the study drug regimen

    Measured: Up to 59 months

  4. ORR as Measured by Immune-related Response Criteria (irRC)

    Treatment response as assessed by irRC instead of RECIST v1.1. ORR is calculated as the number of people with a complete response (CR) or partial response (PR), divided by the total number of people treated. Complete response is defined as complete disappearance of all lesions (whether measurable or not, and no new lesions), confirmed by a repeat, consecutive assessment no less than 4 weeks from the date first documented. Partial response is defined as a decrease in tumor burden ≥ 50% relative to baseline, confirmed by a consecutive assessment at least 4 weeks after first documentation. A lower limit of the true ORR will be estimated by the 90% exact lower confidence bound (LCB) for the binomial proportion.

    Measured: Approximately every 12 weeks until study completion (up to 2 years)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Lanreotide and Pembrolizumab in people with Gastroenteropancreatic Neuroendocrine Tumors, run by Duke University at 2 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 18 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 29 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 28 Sep 2022). 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?

Objective Response Rate (ORR) as Measured by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) (time frame: Approximately every 12 weeks until study completion (up to 2 years)). 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 NCT03043664.

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 29 Jun 2023.
