About this study

Official title: A Phase II Study of Circulating Tumor DNA Directed Consolidation Durvalumab (MEDI4736) Following Induction and Concurrent Durvalumab with SABR for Stage I NSCLC. SCION: SABR and Checkpoint Inhibition of NSCLC

The SCION Trial is a clinical trial in patients with early stage non-small cell lung cancer. The purpose of the trial is to investigate whether it is safe and effective to combine standard radiation treatment with a drug called durvalumab, a type of immunotherapy. In addition, the study will use a blood test to look for cancer cell DNA to determine how long treatment with durvalumab should last. Both the use of durvalumab and the use of the blood test are new strategies for managing early stage non-small cell lung cancer.

Read the detailed description

PURPOSE The intent of the study is to determine whether disease control in early non-small cell lung cancer (NSCLC) achieved by stereotactic ablative body radiotherapy (SABR) can be augmented locally, regionally, and distantly by safely combining it with durvalumab. Moreover, the study will assess whether patients who are likeliest to benefit from extended treatment with durvalumab can be predicted by assaying for molecular residual disease (MRD) after initial treatment using the AVENIO assay for circulating tumor DNA (ctDNA).

HYPOTHESIS Combining SABR and Durvalumab in patients with T1-2 N0 M0 NSCLC reduces the overall relapse rate at 18 months by 50% compared with historical controls treated with SABR alone, from 19.3% to 9.7%.

OBJECTIVES Primary

  • To determine the overall relapse rate at 18 months in patients with T1-2 N0 M0 NSCLC treated with SABR and Durvalumab.

Secondary

  • To determine rates of Local Relapse, Regional Nodal Relapse, Distant Relapse, and Second Primary Lung Cancer in patients with T1-2 N0 M0 NSCLC treated with SABR and Durvalumab.
  • To determine rates of Overall Survival, Cause-Specific Survival, and Relapse Free Survival in patients with T1-2 N0 M0 NSCLC treated with SABR and Durvalumab
  • To determine rates of pneumonitis, immune-related toxicity, adverse events, serious adverse events in patients with T1-2 N0 M0 NSCLC treated with SABR and Durvalumab.
  • To determine the rate of MRD detection using the AVENIO ctDNA assay in patients with T1-2 N0 M0 NSCLC treated with SABR and Durvalumab.
  • To compare clinical outcomes between patients with detectable versus undetectable MRD using the AVENIO ctDNA assay following treatment with SABR and Durvalumab.
  • To compare clinical outcomes between patients with detectable MRD using the AVENIO ctDNA assay following treatment with SABR and Durvalumab who receive extended Durvalumab versus no further therapy.

STUDY DESIGN Subjects who meet the eligibility criteria will be candidates for enrolment. All subjects will receive one infusion of Durvalumab every 4 weeks for four cycles (4 weeks = 1 cycle), with SABR delivered concurrently with cycle 2. Subjects will be assessed at baseline using the AVENIO assay initially on tumor tissue. This will allow the subsequent evaluation for molecular residual disease (MRD) following cycle 4 to be tumor-informed, and ultrasensitive. Subjects with no detectable ctDNA at the MRD assessment will receive no further therapy. Subjects with detectable ctDNA at the MRD assessment will be randomized to receive either no further therapy or 8 additional cycles of q4w Durvalumab. Safety will be evaluated by recording the occurrence of adverse events, serious adverse events, and laboratory abnormalities, with special attention to pneumonitis and immune-related toxicity.

Future research will be enabled through the collection of biospecimens. Subjects will separately consent to the optional collection of these biospecimens. Blood samples collected for this purpose at multiple timepoints (0, 4, 12, 24 months) will be archived in a biorepository created for this study operated by the BC Cancer Tumour Tissue Repository (Victoria, BC). Stool samples collected for this purpose at multiple timepoints (0, 4, and 12 months) will be archived in the Oncomicrobiome Repository (Montreal, QC).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Durvalumab, Stereotactic Body Radiotherapy and Circulating Tumor DNA assay in people with Non Small Cell Lung Cancer and Carcinoma, Non-Small-Cell Lung, run by University of British Columbia at 5 sites in Canada.

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 25 inclusion and 38 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 3 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Canada. 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?

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?

Overall Risk of Relapse (time frame: 18 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 NCT04944173.

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 3 Sep 2024.
