Cladribine Dose Escalation in Conditioning Regimen Prior to Allo-HSCT for Refractory Acute Leukemia and Myelodysplastic Syndromes (CEREAL)

June 26, 2018 updated by: Institut Paoli-Calmettes
The investigators focused on patients with refractory acute leukemia or MDS and designed a phase 1 trial of escalated cladribine doses in the Cla-Flu-Bu RTC regimen using PK-guided myeloablative busulfan doses. This scheme allows combining different optimization of RTC experienced over years (Flu-Bu RTC, PK-guided myeloablative busulfan doses, a second purine analog cladribine) to approach a specific platform to treat refractory diseases.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Fludarabine-Cladribine-Busulfan conditioning regimen
Drug: Fludarabine-Cladribine-Busulfan conditioning regimen

Conditioning regimen will be performed from day -6 to day -2 and contains:

  • Fludarabine 10 mg/m²/d during 5 days (day-6 to day-2).

  • Cladribine during 5 days (day-6 to day-2) at one the following define dose level:

    • Dose 1: 10 mg/m²/d
    • Dose 2: 15 mg/m²/d
    • Dose 3: 20 mg/m²/d
    • Dose 4: 25 mg/m²/d

  • IV busulfan will be given on day-6 using fixed dose as following:

    • If age ≤ 60 years: starting dose of 130 mg/m²
    • If age > 60 years: starting dose of 100 mg/m² No busulfan will be administered at day-5, allowing the pharmacokinetic (PK) analyses . Subsequent infusion of IV busulfan will be performed from day-4 to day-2 at the dose recommended by PK analyses

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
estimation of the maximal tolerable dose,if any,and recommended phase II dose of cladribine administered as in combination with fludarabine and PK-guided IV busulfan prior Allo-HSCT for refractory acute leukemia and myelodysplastic syndrome (MDS)
Time Frame: 30 days after Allo-HSCT
Occurrence ratio of dose-limiting toxicity defined as any grade ≥ 3 toxicity according to CTCAE (version 4.03 ) attributable to conditioning regimen (extra-medullary toxicity), considered to be related or probably related to the Cla-Fu-Bu RTC by the investigator.
30 days after Allo-HSCT

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame
Cumulative incidence of relapse
Time Frame: 1 year
Cumulative incidence of relapse at 1 year
1 year

Time Frame: 100 days
Cumulative incidence of acute Graft versus host disease according to Gluckberg's classification
100 days
Cumulative incidence of chronic Graft versus host disease
