About this study

Official title: Study of Telotristat (Xermelo) in Combination With Luetetium Lu177 Dotatate (Lutathera) in Well-Differentiated Neuroendocrine Tumors

This trial will test the hypothesis that Telotristat treatment increases the antitumor efficacy of Lutetium Lu 177 Dotatate therapy in neuroendocrine tumors (NETs).

Read the detailed description

Neuroendocrine tumors (NETs) are a very heterogeneous group of tumors that develop predominantly in the gastrointestinal and pulmonary systems. Clinical detection and diagnosis are more reliable at late stages when metastatic spread has occurred. Patients with advanced disease may suffer from complications of uncontrolled hormone secretion and usually succumb due to tumor progression.

This trial tests the hypothesis that inhibition of serotonin production with Telotristat will lead to cytostatic effects on neuroendocrine tumors and will complement the anti-tumor activity of Lutetium 177 Dotatate. The proposed combination may result in improved treatment efficacy as reflected by improved 20-month progression-free survival (PFS) as compared to historical control.

What participants receive

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

  • Telotristat (Low-Dose)Drug

    Also called Xermelo

    Participants in this group will receive Lutetium Lu 177 Dotate (Lutathera) by IV every 2 months (Q8weeks) for a total of 4 doses. They will also receive oral Telotristat at 750mg per day (250mg TID) for 20 months.

  • Telotristat (High-Dose)Drug

    Also called Xermelo

    Participants in this group will receive Lutetium Lu 177 Dotate (Lutathera) by IV every 2 months (Q8weeks) for a total of 4 doses. They will also receive oral Telotristat at 1500mg per day (500mg TID) for 20 months.

What is being measured

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

  1. Progression-Free Survival (PFS)

    Progression-free survival at 20 months.

    Measured: 20 months

Secondary outcomes (5)
  1. Overall Response Rate (ORR)

    Overall response rate using RECIST v1.1 at 6 and 12 months after therapy

    Measured: 6 and 12 months

  2. Median Progression-Free Survival (PFS)

    Median progression-free survival.

    Measured: 36 month

  3. Urinary 5-HIAA

    Levels of urinary 5-Hydroxyindoleacetic acid (5-HIAA) will be measured at baseline and 12 months.

    Measured: Baseline and 12 months

  4. Quality of Life (QLQ-C30)

    The Quality of Life Questionnaire C30 (QLQ-C30) was developed by the European Organization for Research and Treatment of Cancer (EORTC) to assess quality of life in cancer patients.It includes five function domains (physical, emotional, social, role, cognitive), eight symptoms (fatigue, pain, nausea/vomiting, constipation, diarrhea, insomnia, dyspnea, and appetite loss), as well as global health/quality-of-life and financial impact. Subjects respond on a four-point scale from "not at all" to "very much" for most items.Raw scores are linearly converted to a 0-100 scale with higher scores reflecting higher levels of function and higher levels of symptom burden.

    Measured: 20 month

  5. Quality of Life (QLQ-GI.NET21)

    The Quality of Life GI Neuroendocrine Tumor survey (QLQ-GINET21) contains a total of 21 items: four single-item assessments relating to muscle and/or bone pain (MBP), body image (BI), information (INF) and sexual functioning (SX), together with 17 items organised into five proposed scales: endocrine symptoms (ED; three items), GI symptoms (GI; five items), treatment-related symptoms (TR; three items), social functioning (SF) and disease-related worries (DRW; three items). The response format of the questionnaire is a four-point Likert scale. Responses are linearly transformed to a 0-100 scale using EORTC guidelines, with higher scores reflecting more severe symptoms.

    Measured: 20 month

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Telotristat (Low-Dose) and Telotristat (High-Dose) in people with Neuroendocrine Tumors, run by Lowell Anthony, MD 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 6 inclusion and 9 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: stopped early, as of the sponsor's last update on 27 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 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?

Yes. Results are posted in the registry (first posted 27 Jun 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?

Progression-Free Survival (PFS) (time frame: 20 months). 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 27 Jun 2023.
