About this study

Official title: A Phase 2, Open-label Study of Selinexor (KPT-330) in Patients With Advanced Thymic Epithelial Tumor (TET) Progressing After Primary Chemotherapy (SELECT)

The purpose of this study is to evaluate the safety, tolerability and effectiveness of selinexor in patients with advanced thymic epithelial tumor progressing after primary chemotherapy. This is a multicenter, open label phase II trial that uses a Simons two stage design. The study population is adults with histologically confirmed, advanced, inoperable TETs who are progressing after treatment with at least one platinum containing chemotherapy regimen.

This study is comprised of 2 similar phase II trials, one running in US (25 patients) and one running in EU (25 patients):

What is being measured

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

  1. Overall Response Rate

    To determine the overall response rate per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by CT: Complete Response (CR), Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR+ PR.

    Measured: 24 months

Secondary outcomes (4)

  1. Overall Response Rate

    To determine the overall response rate to according to modified ITMIG response criteria. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT and MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

    Measured: 24 months

  2. 6 Month Progression Free Survival Rate

    To determine six months progression free survival of patients with TET treated with selinexor

    Measured: 6 months

  3. 24 Month Overall Survival Rate

    To determine overall survival of patients with TET treated with selinexor

    Measured: 24 months

  4. Adverse Events

    The number of adverse events as determined by Common Terminology Criteria for Adverse Events (CTCAEs) version 4.03

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Open Label Selinexor in people with Thymoma and Advanced Thymic Epithelial Tumor, run by Georgetown 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 16 inclusion and 13 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 16 Feb 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 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 16 Feb 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?

Overall Response Rate (time frame: 24 months). 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 NCT03193437.

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 16 Feb 2023; AzTrials last refreshed its copy on 6 Nov 2026.
