About this study
Official title: Radio-Immuno-Modulation for Advanced Lung Cancer: a Pilot Study Evaluating Tolerance and Immune Responses
This project will assess the feasibility of treating advanced cancer using the immune system, without any anti-cancer drug. In this pilot study, the investigators propose combining low-dose radiotherapy, in lung cancer patients, with allogeneic immune cells obtained from a donor. The patients will receive radiotherapy directed to one of the patient's tumors, as well as an immunomodulatory drug called cyclophosphamide. Thereafter, they will receive the infusion of donor immune cells.
Read the detailed description
Metastatic lung cancer remains incurable despite numerous studies and treatments tried, including chemotherapy and, more recently, targeted therapies.
Cancer can escape immune surveillance through different mechanisms: low levels of tumor associated antigens (TAA), regulatory T cells, and immunosuppressive cytokines. Non-cytolytic doses of radiation have been shown to reverse some of these pathways in experimental models. It up-regulated the density of the MHC molecules presenting TAA and increased the T cell infiltration of the tumor (1). Patients with lymphoma, liver or prostate cancer were treated with radiotherapy combined with immunotherapy, in the form of a TLR9 agonist, autologous dendritic cells or a prostate-specific antigen vaccine (2, 3, 4). These trials have shown an induction of T cell reactivity against TAA. Another form of immunotherapy, used for patients with refractory hematologic malignancies is allogeneic hematopoietic stem cell transplantation (HSCT) (5). Its success has relied on cell infusions from a donor, demonstrating the immunologic control sustained by allogeneic cells (6).
The approach investigated in this study uses the immune cells from a donor to induce a tumor destruction reaction. This will be amplified by the immunological effects of radiotherapy. Many oncogenes are present in lung cancers and low-dose radiation increases their expression on the surface of the tumor cell. In addition, radiation has the property to stimulate the production of inflammatory cytokines and chemokines in the irradiated site. Finally, the donor's immune cells shall respond physiologically by migrating to the site of inflammation. This will trigger an immune reaction directed against the abnormal cancer cells.
A total of 24 patients are expected to be recruited over the study period, estimated to be 3 years. The allogeneic cells will be obtained from one of two possible donor types. For patients having a living donor, the immune cells will be harvested through a collection procedure called apheresis. The living donor should be a sibling with 3/6 or less HLA compatibility with the patient, at the A, B and DRB1 loci. For patients who do not have such a living donor, allogeneic cells from a cryopreserved umbilical cord blood (UCB) unit will be used.
The treatment course will be the following: low-dose radiotherapy will be delivered to a single tumor site, which could be either the primary tumor or one of its metastases. Low-dose cyclophosphamide will be given to decrease regulatory T cell activity and increase anti-tumor responses. Allogeneic immune cells will be administered thereafter, according to the treatment arm the patient has been assigned.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Patients with a living donorBiological
The day of allogeneic cell infusion will be referred to as Day 0 and the n-th day before that, as Day -n. The dose of external radiation will be 15 Gy divided in 3 fractions, from Day -3. Cyclophosphamide, 250 mg/m2 will be given on Day -2. Donors will receive 5 daily doses of GCSF, 10 µg/kg, by subcutaneous injection from Day -4. PBMC will be collected through apheresis on Day 0. A dose of 5 x 10exp7 CD3 cells/kg will be administered. The infused volume will be adjusted to contain this T cell dose.
Patients with a UCB donorBiological
The day of allogeneic cell infusion will be referred to as Day 0 and the n-th day before that, as Day -n. The UCB unit should have at least 4 of 6 HLA compatibility and at least 3 x 10exp6 TNC per kg patient weight. The dose of external radiation will be 15 Gy, divided in 3 fractions, starting on Day -3. Cyclophosphamide, 250 mg/m2 intravenously, will be given on Day -2.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of treatment-related adverse events
Evaluation by follow-up clinic visits, including medical questionnaire, physical exam \& blood tests: complete blood count, electrolytes, renal \& liver function tests. AE will be graded using National Cancer Institute's Common Toxicity Criteria version 3 (7). Evaluations will take place twice a week for the first 2 weeks, weekly for 2 weeks, every 2 weeks for 2 months \& every month for 3 months. It is anticipated that a maximum of 1 of 6 patients will have grade 3 side effects, including nausea, diarrhea, dyspnea, cough, fever, rash.
Measured: Up to 6 months
Secondary outcomes (4)
Immune responses - T cell infiltration
Assessment using biopsies done before \& 1-2 weeks after treatment. The block slides will be stained with CD3, CD4, CD8 \& PDL-1 antibodies. T cell density will be expressed as the number of CD4+ and CD8+ cells to tumor cell ratio. The degree of T cell infiltration of the tumors will be assessed by comparing these ratios between pre \& post treatment samples.
Measured: Up to 1 month
Immune responses - Tumor cell phenotype
Assessment using biopsies done before \& 1-2 weeks after treatment. Flow cytometry will be used to assess the following tumor markers: HLA, Fas, ICAM-1, PDL-1. The changes in tumor cell phenotypes will be assessed by comparing the mean fluorescence intensity of the above markers between pre \& post treatment samples. The PDL-1 tumor cell expression will also be compared on the block slides between pre \& post treatment samples.
Measured: Up to 1 month
Immune responses - tumor infiltrating T cell phenotype
Assessment using biopsies done before \& 1-2 weeks after treatment. Flow cytometry will be used to assess the following markers on tumor infiltrating T cells: CD3, CD4, CD8, CD25 \& Foxp3. The nature and magnitude of T cell infiltration will be assessed by comparing the frequencies of these T cell subsets between pre \& post treatment samples.
Measured: Up to 1 month
Immune responses - origin of tumor infiltrating T cells
Assessment using biopsies done 1-2 weeks after treatment. Single cell suspensions will be stained with the following markers for tumor infiltrating T cells: CD3, CD4 and CD8. CD4+ and CD8+ T cells will be isolated by fluorescence-activated cell sorting. Their origin (patient vs donor) will be determined by a chimerism assay. The frequencies of donor-derived cells will be determined by PCR quantification of patient and donor specific VNTR bands.
Measured: Up to 1 month

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Patients with a living donor and Patients with a UCB donor in people with Lung Cancer, run by Centre Integre Universitaire de Sante et Services Sociaux du Nord de l'ile de Montreal at 1 site 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 7 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: paused, as of the sponsor's last update on 29 Feb 2024. 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 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 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.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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?
Incidence of treatment-related adverse events (time frame: Up to 6 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 NCT02579005, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
