About this study
Official title: Autologous Cytokine Induced Killer Cells as Adjuvant Adoptive Immunotherapy in Patients With Chronic Myeloid Leukemia on Standard Drug Therapy
This is an extension of our ongoing clinical trial using ex vivo expanded autologous Cytokine-induced killer (CIK) cells as an adoptive cellular immunotherapy for haematological malignancies. The pre-existing clinical trial targets patient with acute myeloid leukemia or MDS, and relapsed disease post allogeneic transplant.
Chronic myeloid leukemia (CML) is a disease with good response to kinase inhibitors. There are however patients in transformed phase of the disease who do not respond to these treatment. A small proportion of patients with response to Imatinib may develop mutations resulting in drug resistance. In addition, the vast majority of patients with a good response to the kinase inhibitors still have persistent CML cells detectable at a molecular level. It is known that the CML progenitors are not sensitive to the kinase inhibitors. On the other hand, immune mediated mechanism is known to be able to eradicate CML as shown by efficacy of donor lymphocyte infusion in the allogeneic transplant setting. Early clinical trials have shown clearance of bcr-abl using peptide vaccination. There is also convincing mouse data showing eradication of CML at molecular level by autologous CIK cells, but no clinical trial has been done using CIK cells for CML.
We therefore plan to expand our current CIK trial to include CML as a disease, for CML patients with various degree of response to the kinase inhibitors which have already offered its maximal effect. We aim to study whether autologous CIK cells may further improve disease response, either in the eradiation of minimal residual disease, or in conjunction with chemotherapy for control of high tumour load disease.
Read the detailed description
Patients with CML falls into various groups based on their disease stage and response to kinase inhibitors. In the context of currently available kinase inhibitors, allogeneic transplant and the various available new drug trials, there are still some patients who will not achieve a satisfactory or sustainable response. For such patients, we aim to employ CIK cell as an immunotherapeutic modality concurrent with their original CML-specific therapy. This will enable us to explore any additional activity of CIK cells against CML without any compromise to their ongoing, established treatment.
The following groups of patients are potential candidates:
- Blast crisis / accelerated phase patients who have failed to response to the kinase inhibitors but are fit to undergo induction chemotherapy as for the acute leukemia. Repeated cycles of CIK will be given in phase with the planned chemotherapy cycles, to observe for achievement of any remission and its durability.
- Blast crisis / accelerated phase patients who have achieved a haematological or cytogenetic response to the kinase inhibitors, but do not have further definitive curative options eg allogeneic transplant. In the absence of long term data with Dasatinib or Nilotinib , it is justifiable to study the efficacy of addition of CIK therapy to their baseline best response achievable with drug therapy.
- Patients with resistance to the currently available kinase inhibitors due to T315I mutation or other undefined mutations, with progressive relapse either at molecular, cytogenetic or haematological level, and do not have transplant as a curative option. In this group of patients additional of CIK to current treatment will show any activity of CIK against the drug-resistant mutant CML cells.
- Patients who have achieved a stable but residual molecular evidence of CML, who are willing to explore additional means with a hope to eradication of MRD. Since the role of immunotherapy is most relevant in MRD, CIK infusion will provide the proof of principal observation of whether imatinib-resistant CML Philadelphia stem cells can be eradicated by these ex vivo activated and expanded cytotoxic T cells.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Autologous CIK cell infusionBiological
4 CIK cells will be infused into patients at regular 3-weekly intervals for 4 infusions. The target cell dose per infusion is 1x10e10 CD3 cells. For patients with uncontrolled accelerated or blastic transformation undergoing chemotherapy, this will be given at the nadir of lymphopenia following chemotherapy. For other patients this will be given without interruption of the ongoing treatment with Imatinib or other kinase inhibitor.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is an extension of our ongoing clinical trial using ex vivo expanded autologous Cytokine-induced killer (CIK) cells as an adoptive cellular immunotherapy for haematological malignancies. The pre-existing clinical trial targets patient with acute myeloid leukemia or MDS, and relapsed disease post allogeneic transplant.
Chronic myeloid leukemia (CML) is a disease with good response to kinase inhibitors. There are however patients in transformed phase of the disease who do not respond to these treatment. A small proportion of patients with response to Imatinib may develop mutations resulting in drug resistance. In addition, the vast majority of patients with a good response to the kinase inhibitors still have persistent CML cells detectable at a molecular level. It is known that the CML progenitors are not sensitive to the kinase inhibitors. On the other hand, immune mediated mechanism is known to be able to eradicate CML as shown by efficacy of donor lymphocyte infusion in the allogeneic transplant setting. Early clinical trials have shown clearance of bcr-abl using peptide vaccination. There is also convincing mouse data showing eradication of CML at molecular level by autologous CIK cells, but no clinical trial has been done using CIK cells for CML.
We therefore plan to expand our current CIK trial to include CML as a disease, for CML patients with various degree of response to the kinase inhibitors which have already offered its maximal effect. We aim to study whether autologous CIK cells may further improve disease response, either in the eradiation of minimal residual disease, or in conjunction with chemotherapy for control of high tumour load disease.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Autologous CIK cell infusion in people with Chronic Myeloid Leukemia, run by Singapore General Hospital at 1 site in Singapore.
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 8 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: finished, as of the sponsor's last update on 10 Feb 2017. 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 Singapore. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
response of CML to Cytokine induced killer cell therapy (time frame: 6 -12 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 NCT00815321, which also lists 12 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 10 Feb 2017.
