Trial summary

Background: Imaging studies like positron emission tomography (PET) and computed tomography (CT) scans are used to detect tumor responses to cancer treatment. However, it may be difficult to detect early response to lung cancer or thymoma treatment with standard PET/CT scans. Read more about this study

About this study

Official title: A Pilot Study of 18F FLT PET/CT in Evaluating Early Response to Anti-Proliferative Therapies in Non Small Cell Lung Cancer and Thymic Tumors

Background:

  • Imaging studies like positron emission tomography (PET) and computed tomography (CT) scans are used to detect tumor responses to cancer treatment. However, it may be difficult to detect early response to lung cancer or thymoma treatment with standard PET/CT scans. These scans cannot easily show a difference between remaining cancer cells and inflammation. Researchers want to try a new PET/CT scan tracer that may be able to show the difference between these cells. 18F-Fluorothymidine (18F-FLT) is better at showing which cells are still actively dividing. PET/CT scans with 18F-FLT may help show if tumor cells are responding to early stages of treatment.

Objectives:

  • To see if 18F-FLT is a safe and effective imaging study tracer to show early cancer response to treatment.

Eligibility:

  • Individuals at least 18 years of age who are being treated for lung cancer or thymoma.

Design:

  • Participants will be screened with a physical exam and medical history. Blood, urine, and tumor tissue samples will be collected.
  • Participants will have two PET/CT scans on separate days before starting chemotherapy. One scan will be with a standard radiotracer. The other will be with the 18F-FLT tracer.
  • About 2 weeks after starting chemotherapy, participants will repeat the two PET/CT scans on separate days. Additional blood samples will be collected at this time.
Read the detailed description

Background:

  • (18)F FLT, a thymidine analog, has uptake in tumors that correlates with proliferative rates and may be an early predictor of tumor response.
  • Due to uptake in inflammatory tissues, routinely used (18)F FDG PET/CT is often unable to distinguish therapeutic response from reactive change early in therapy.
  • Molecularly targeted therapies relating to the MEK kinase pathway in non small cell lung cancer (NSCLC) and the IGF pathway (anti-IGF-1R monoclonal antibodies) in thymoma, affect tumor proliferation.
  • We intend to explore the potential utility of (18)F FLT PET/CT imaging as an early marker of therapeutic response in molecularly targeted therapies relating to the MEK kinase pathway in NSCLC and the IGF pathway in thymic tumors.

Objectives:

-To explore the relationship between change in (18)F FLT tumor uptake (pre-treatment and soon after initiation of treatment (2 weeks)) and progression free survival in NSCLC patients treated with AZD6244 and in thymoma patients with IMC-A12, Cixutumumab

Eligibility:

  • Subjects with pathology proven lung cancer or thymoma enrolled in an NCI therapy protocol.
  • Participant must be 18 years or older and have ECOG Performance of less than or equal to 2.
  • Patients must have measurable disease by RECIST criteria.
  • Patients must have the ability to provide informed consent. All subjects must sign a document of informed consent indicating their understanding of the investigational nature and risks of the study before any protocol related studies are performed.

Design:

-This is a pilot study which will incorporate (18)F FLT and (18)F FDG PET/CT imaging sessions prior to therapy with AZD6244, Selumetinib, in NSCLC and IMC-A12, Cixutumumab, in thymoma, and 2 weeks (+/- 4 days) following therapy initiation. The imaging parameters will be evaluated with respect to clinical response (as determined under the referring protocol). We expect to enroll 24 evaluable patients in this single center study.

  • PET/CT scanOther

What is being measured

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

  1. To explore the relationship between change in 18F FLT tumor uptake and progression free survival in NSCLC patients treated with AZD6244 and in thymoma patients with IMC-A12, Cixutumumab

Secondary outcomes (2)
  1. To explore the relationship between the absolute pre-treatment 18F FLT uptake and the clinical response to therapy

  2. To determine if the change in 18F FLT uptake is different from the change in 18F FDG PET/CT at the same time points

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 3'-deoxy-3'-18F fluorothymidine (FLT) and PET/CT scan in people with Carcinoma, Non-Small-Cell Lung and Thymus Neoplasms, run by National Cancer Institute (NCI).

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 5 inclusion and 5 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: withdrawn, as of the sponsor's last update on 5 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

To explore the relationship between change in 18F FLT tumor uptake and progression free survival in NSCLC patients treated with AZD6244 and in thymoma patients with IMC-A12, Cixutumumab. 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 NCT01610544, which also lists 3 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 5 Jul 2018.
