About this study
Official title: Phase I/II Study of Plerixafor and Clofarabine in Previously Untreated Older (>/=60 Years) Adult Patients With Acute Myelogenous Leukemia (AML) With Two or More Unfavorable Prognostic Factors for Whom Standard Induction Chemotherapy is Unlikely to be of Benefit
The goal of Part 1 of this clinical research study is to learn about the safety of the combination of plerixafor and clofarabine when given to patients with previously untreated AML who are at least 60 years old.
The goal of Part 2 of this study is to learn if the combination of plerixafor and clofarabine can help to control previously untreated AML in patients who are at least 60 years old. Study was closed early and did not progress to Part 2.
Read the detailed description
The Study Drugs:
Plerixafor is designed to block a protein on cancer cells from attaching to cells in the bone marrow. This may allow cells in the bone marrow to be more effectively treated by chemotherapy.
Clofarabine is designed to interfere with the growth and development of cancer cells.
Study Groups:
If you are found to be eligible to take part in this study, you will be assigned to a study group based on when you joined this study. Up to 3 groups of up to 6 participants will be enrolled in the Part 1 portion of the study, and up to 48 participants will be enrolled in Part 2.
If you are enrolled in Part 1, the dose of plerixafor you receive will depend on when you joined this study. The first group of participants will receive the lowest dose level of plerixafor. Each new group will receive a higher dose of plerixafor than the group before it, if no intolerable side effects were seen.
If you are enrolled in Part 2, you will receive plerixafor at the highest dose that was tolerated in Part 1.
All participants will receive the same doses of clofarabine.
Study Drug Administration:
Cycles in this study are 28 days long, or possibly longer depending on your blood counts, any side effects, and the status of the disease.
On Days 1-5 of each cycle, you will receive plerixafor through a needle under the skin of your abdomen.
On Days 1-5 of each cycle, you will receive clofarabine by vein over about 1 hour. The dose will begin about 4 to 6 hours after the plerixafor injection. You will be watched for side effects while you receive clofarabine.
If the doctor thinks it is in your best interest, the dose level of plerixafor may be lowered.
Cycle 1 is called Induction. If the disease goes into remission (responds well) after the Induction cycle, you will start the Consolidation part of the study. In the Consolidation cycles, the schedule of administration of the drugs will be the same as in the Induction cycle, but the doses of clofarabine will be lower. If the disease does not go into remission after the Induction cycle, you will have a Reinduction cycle before you can begin the Consolidation part of the study. The goal of the Induction cycle and possible Reinduction cycle is to affect the bone marrow a certain way that may help control the disease. The goal of Consolidation is also to help control the disease.
Study Visits:
Induction (Cycle 1):
On Day 1 of Induction, blood (about ½ tablespoon each time) will be drawn for routine tests before the plerixafor injection and 3 times during the 8 hours after the injection.
On Days 2-5 of Induction, blood (about ½ tablespoon each time) will be drawn for routine tests before the plerixafor injection and again at 8 hours after the injection.
Starting in Week 2 of Induction, blood (about 2 tablespoons) will be drawn at least 2 times a week for routine tests.
You will have a bone marrow aspiration and/or biopsy to check the status of the disease on Day 21 of Induction and every 2 weeks after that, until the Induction cycle is over.
Reinduction:
If you have a Reinduction cycle, blood (about 2 tablespoons) will be drawn at least 2 times a week during Reinduction for routine tests. You will have a bone marrow aspiration and/or biopsy to check the status of the disease on Day 21 of Reinduction and every 2 weeks after that, until the Reinduction cycle is over.
Consolidation:
Blood (about 2 tablespoons) will be drawn 1 time a day for routine tests on Days 1-5 of Consolidation.
Starting in Week 2 of each Consolidation cycle, blood (about 2 tablespoons) will be drawn for routine tests every week for the rest of each Consolidation cycle.
You will have a bone marrow aspiration and/or biopsy to check the status of the disease anytime during Consolidation that the doctor decides it is needed.
Induction, Reinduction, and Consolidation:
The blood tests and/or bone marrow aspirations/biopsies may be performed more often than listed if the doctor thinks it is needed. Also, you will have an ECG anytime during the study if the doctor thinks it is needed.
Length of Study:
You may continue taking the study drugs for up to 5 Consolidation cycles, if the doctor thinks it is in your best interest. You will no longer be able to take the study drugs if the disease gets worse or intolerable side effects occur.
Your participation on the study will be over once you have completed the follow-up visits.
Follow-Up Visits:
At 1 and 3 months after you stop taking the study drugs:
- Blood (about 2 tablespoon) will be drawn for routine tests.
- If the doctor decides it is needed, you will have a bone marrow aspiration to check the status of the disease.
If the disease responds (if it goes into complete or partial remission), you will have follow-up visits every 3 months for up to 2 years after you stop taking the study drugs. The follow-up visits will stop if the disease gets worse, or if you start a new cancer therapy and the disease has not gotten worse. The following tests and procedures will be performed at the follow-up visits:
- Blood (about 2 tablespoon) will be drawn for routine tests.
- If the doctor decides it is needed, you will have a bone marrow aspiration to check the status of the disease.
This is an investigational study. Clofarabine is FDA approved and commercially available to treat acute lymphoblastic leukemia (ALL) in children after the disease has gotten worse a second time. Plerixafor is FDA approved to be given with G-CSF and is commercially available for use in moving stem cells into the bloodstream before a stem cell transplant to treat non-Hodgkin's lymphoma or multiple myeloma. The combination of clofarabine and plerixafor is investigational.
Up to 66 patients will take part in this study. All will be enrolled at MD Anderson.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants in Phase I With First Cycle Dose Limiting Toxicities (DLT) Observed
Dose limiting toxicity (DLT) consists of participants who developed DLT during maximum tolerated dose (MTD) estimation period where DLTs observed during dose escalation were used to develop MTD. The MTD is the highest dose level in which <2 participants of 6 develop first cycle. DLT. Toxicity graded according to the NCI Common Toxicity Criteria Version 3.0. The timeframe to assess dose-limiting toxicities (DLT's) will be the first cycle of treatment, i.e. the first 4 weeks on study. The Plerixafor dose to be used in Phase II of the protocol is the highest dose at which no more than 1 of 6 patients experience a DLT in the Phase I part of the protocol or a lower dose selected at the end of dose escalation.
Measured: First cycle of treatment, i.e. first 4 weeks on study
Secondary outcomes (2)
Participants' Response During First Part of Study
Response defined as Complete remission (CR): Disappearance all clinical +/or radiologic evidence disease. Neutrophil count >/=1.0x10^9/L \& platelet count >/=100x10^9/L, \& normal bone marrow differential (</= 5% blasts). Complete Remission without Platelet Recovery (CRp): Peripheral blood \& bone marrow results as for CR, but with platelet counts of <100x10^9/L. Partial Remission (PR): Blood count recovery as for CR, but both decrease in marrow blasts >50% \& not more than 6 to 25% abnormal cells in the marrow.
Measured: Assessments following 3 cycles (at 12 weeks) up to 5 cycles (20 weeks)
Number of Participants With Overall Response During Second Part of Study
Overall response (OR) = Complete Remission (CR) + Partial Remission (PR) where response defined: Complete remission (CR): Disappearance all clinical +/or radiologic evidence disease. Neutrophil count >/=1.0x109/L \& platelet count >/=100x10^9/L, \& normal bone marrow differential (</= 5% blasts). Complete Remission without Platelet Recovery (CRp): Peripheral blood \& bone marrow results as for CR, but with platelet counts of <100x10^9/L. Partial Remission (PR): Blood count recovery as for CR, but both decrease in marrow blasts >50% \& not more than 6 to 25% abnormal cells in the marrow. Treatment Failure: For purposes of efficacy analysis of remission, less than a CR, CRi, or PR categorized as Treatment Failure.
Measured: Continuously monitored, assessments at 12 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The goal of Part 1 of this clinical research study is to learn about the safety of the combination of plerixafor and clofarabine when given to patients with previously untreated AML who are at least 60 years old.
The goal of Part 2 of this study is to learn if the combination of plerixafor and clofarabine can help to control previously untreated AML in patients who are at least 60 years old. Study was closed early and did not progress to Part 2.
Detailed description
The Study Drugs:
Plerixafor is designed to block a protein on cancer cells from attaching to cells in the bone marrow. This may allow cells in the bone marrow to be more effectively treated by chemotherapy.
Clofarabine is designed to interfere with the growth and development of cancer cells.
Study Groups:
If you are found to be eligible to take part in this study, you will be assigned to a study group based on when you joined this study. Up to 3 groups of up to 6 participants will be enrolled in the Part 1 portion of the study, and up to 48 participants will be enrolled in Part 2.
If you are enrolled in Part 1, the dose of plerixafor you receive will depend on when you joined this study. The first group of participants will receive the lowest dose level of plerixafor. Each new group will receive a higher dose of plerixafor than the group before it, if no intolerable side effects were seen.
If you are enrolled in Part 2, you will receive plerixafor at the highest dose that was tolerated in Part 1.
All participants will receive the same doses of clofarabine.
Study Drug Administration:
Cycles in this study are 28 days long, or possibly longer depending on your blood counts, any side effects, and the status of the disease.
On Days 1-5 of each cycle, you will receive plerixafor through a needle under the skin of your abdomen.
On Days 1-5 of each cycle, you will receive clofarabine by vein over about 1 hour. The dose will begin about 4 to 6 hours after the plerixafor injection. You will be watched for side effects while you receive clofarabine.
If the doctor thinks it is in your best interest, the dose level of plerixafor may be lowered.
Cycle 1 is called Induction. If the disease goes into remission (responds well) after the Induction cycle, you will start the Consolidation part of the study. In the Consolidation cycles, the schedule of administration of the drugs will be the same as in the Induction cycle, but the doses of clofarabine will be lower. If the disease does not go into remission after the Induction cycle, you will have a Reinduction cycle before you can begin the Consolidation part of the study. The goal of the Induction cycle and possible Reinduction cycle is to affect the bone marrow a certain way that may help control the disease. The goal of Consolidation is also to help control the disease.
Study Visits:
Induction (Cycle 1):
On Day 1 of Induction, blood (about ½ tablespoon each time) will be drawn for routine tests before the plerixafor injection and 3 times during the 8 hours after the injection.
On Days 2-5 of Induction, blood (about ½ tablespoon each time) will be drawn for routine tests before the plerixafor injection and again at 8 hours after the injection.
Starting in Week 2 of Induction, blood (about 2 tablespoons) will be drawn at least 2 times a week for routine tests.
You will have a bone marrow aspiration and/or biopsy to check the status of the disease on Day 21 of Induction and every 2 weeks after that, until the Induction cycle is over.
Reinduction:
If you have a Reinduction cycle, blood (about 2 tablespoons) will be drawn at least 2 times a week during Reinduction for routine tests. You will have a bone marrow aspiration and/or biopsy to check the status of the disease on Day 21 of Reinduction and every 2 weeks after that, until the Reinduction cycle is over.
Consolidation:
Blood (about 2 tablespoons) will be drawn 1 time a day for routine tests on Days 1-5 of Consolidation.
Starting in Week 2 of each Consolidation cycle, blood (about 2 tablespoons) will be drawn for routine tests every week for the rest of each Consolidation cycle.
You will have a bone marrow aspiration and/or biopsy to check the status of the disease anytime during Consolidation that the doctor decides it is needed.
Induction, Reinduction, and Consolidation:
The blood tests and/or bone marrow aspirations/biopsies may be performed more often than listed if the doctor thinks it is needed. Also, you will have an ECG anytime during the study if the doctor thinks it is needed.
Length of Study:
You may continue taking the study drugs for up to 5 Consolidation cycles, if the doctor thinks it is in your best interest. You will no longer be able to take the study drugs if the disease gets worse or intolerable side effects occur.
Your participation on the study will be over once you have completed the follow-up visits.
Follow-Up Visits:
At 1 and 3 months after you stop taking the study drugs:
- Blood (about 2 tablespoon) will be drawn for routine tests.
- If the doctor decides it is needed, you will have a bone marrow aspiration to check the status of the disease.
If the disease responds (if it goes into complete or partial remission), you will have follow-up visits every 3 months for up to 2 years after you stop taking the study drugs. The follow-up visits will stop if the disease gets worse, or if you start a new cancer therapy and the disease has not gotten worse. The following tests and procedures will be performed at the follow-up visits:
- Blood (about 2 tablespoon) will be drawn for routine tests.
- If the doctor decides it is needed, you will have a bone marrow aspiration to check the status of the disease.
This is an investigational study. Clofarabine is FDA approved and commercially available to treat acute lymphoblastic leukemia (ALL) in children after the disease has gotten worse a second time. Plerixafor is FDA approved to be given with G-CSF and is commercially available for use in moving stem cells into the bloodstream before a stem cell transplant to treat non-Hodgkin's lymphoma or multiple myeloma. The combination of clofarabine and plerixafor is investigational.
Up to 66 patients will take part in this study. All will be enrolled at MD Anderson.

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 combined 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.
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 10 May 2019). 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?
Number of Participants in Phase I With First Cycle Dose Limiting Toxicities (DLT) Observed (time frame: First cycle of treatment, i.e. first 4 weeks on study). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 28 Aug 2019.
