Benefit of Allogeneic Haematopoietic Stem Cells in Cutaneous T-cell Lymphomas Epidermotropic With Advanced Stage and Poor Prognosis (CUTALLO)

April 29, 2024 updated by: Assistance Publique - Hôpitaux de Paris

Prospective, Controlled, Multicenter Cohort Study Evaluating the Benefit of Allogeneic Haematopoietic Stem Cells in Cutaneous T-cell Lymphomas Epidermotropic With Advanced Stage and Poor Prognosis

Epidermotropic T-cell lymphomas (ETCL), i.e. mycosis fungoides (MF) and its leukemic variant, Sézary syndrome, are the most frequent subtypes of cutaneous T-cell lymphomas. MF typically runs an indolent course in its early stages. By contrast, advanced-stage ETCLs share a very bad prognosis: Patients usually show early relapses after chemotherapy, prolonged complete remissions exceptionally occur and quality of life is severely affected. Several publications have reported durable responses following allogeneic hematopoietic stem cell transplantation (HSCT) in advanced-stage ETCLs. This study aims to investigate the role of allogeneic HSCT in treating advanced-stage ETCLs. An observational, prospective, multicenter, controlled study will compare the outcomes of patients who receive reduced-intensity conditioned allogeneic HSCT from a sibling or 10/10 HLA-matched unrelated donor to those of patients who receive standard of care in patients with advanced-stage ETCL with poor prognostic features, will be performed. Patients are included at the time of donor search irrespective of the results, and compared on a donor versus no donor basis. It is an observational study since no intervention is made except the comparison of outcomes of groups that receive usual care (HSCT if donor available, or not).

Study Overview

Status

Status

Active, not recruiting

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

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.

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.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Advanced-stage epidermotropic T-cell lymphomas (ETCL), i.e. mycosis fungoides (MF) and its leukemic variant, Sézary syndrome

Inclusion Criteria:

  • Early histological large-cell transformation, i.e. within two years following ETCL diagnosis
  • Histologically proven nodal (ISCL / EORTC N3) or extra-cutaneous visceral involvement by the lymphoma

Exclusion Criteria:

  • Prior allogeneic HSCT
  • Other progressive neoplastic disease
  • Progressive psychotic disease
  • Left ventricular ejection fraction < 50% (as determined by trans-thoracic echocardiography)
  • Pulmonary disease with FEV1, FVC or DLCO <30% of expected corrected for hemoglobin.
  • Creatinine clearance <50 ml/min or requiring dialysis
  • Transaminases or bilirubin >two-fold the normal value in the absence of liver involvement by the lymphoma
  • Pregnant or breastfeeding woman
  • Patient with no health coverage
  • Patient under guardianship or curatorship

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
HSCT
Patients with an available sibling or 10/10 HLA-matched unrelated donor who undergo reduced-intensity conditioned allogeneic hematopoietic stem cell transplantation (HSCT), will be included in the study. The reduced-intensity conditioning usually includes Fludarabine 90 mg/m2 IV and Melphalan 140 mg/m2 IV. As usual care, patients will receive peripheral blood stem cells from their sibling donor if available, otherwise from their 10/10 HLA-matched unrelated donor
Procedure: HSCT
Hematopoietic stem cell transplantation
Standard care
Patients with no available sibling or 10/10 HLA-matched unrelated donor who therefore do not receive allogeneic HSCT but receive best standard of care treatment, will be included in the study, as the control group
Other: Standard Care

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.

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.
