Study Description
Brief Summary:
The present project aims at comparing two nonmyeloablative regimens currently used in 2 major HCT centers in the US for patients with HLA-matched related or unrelated donor: the one from the Seattle group consisting of 2 Gy TBI with fludarabine (90 mg/m²) versus the one from the Stanford group combining 8 Gy TLI with ATG.

Condition or disease Intervention/treatment Phase
Hematological Malignancies Drug: Conditioning regimen TBI + Fludarabine Drug: Conditioning regimen II (TLI 8 Gy + ATG [Thymoglobulin]) Phase 2

Arms and Interventions

Arm Intervention/treatment
Active Comparator: 1
Conditioning regimen consisting of fludarabine 30 mg/m2 on days -4, -3 and -2 (total dose 90 mg/m2), followed by a singe dose of 2 Gy TBI administered on day 0, at a low dose-rate (≈ 7 cGy/min), before infusion of cells.
Drug: Conditioning regimen TBI + Fludarabine
2 Gy TBI, Fludarabine 90 mg/m²
Active Comparator: 2
Conditioning consisting of 8 Gy TLI and ATG. TLI will be administered by linear accelerator at a dose of 80 cGy daily, starting 11 days before transplantation, until a total of 10 doses (800 cGy) has been delivered. The irradiation will consist of a supradiaphragmatic mantle field, a subdiaphragmatic field including an inverted Y and splenic ports, encompassing all major lymphoid organs, including the thymus, spleen, and lymph nodes, as used in the treatment of Hodgkin's disease (Kaplan HS, Cancer Research 26:1268-1276, 1966). The Waldeyer ring is not included. ATG (Thymoglobulin®, Genzyme), at a dose of 1.5 mg/kg/d, will be given intravenously on days -11 through -7.
Drug: Conditioning regimen II (TLI 8 Gy + ATG [Thymoglobulin])
TLI 8 Gy + ATG (Thymoglobulin) 7.5 mg/kg

Outcome Measures

Primary Outcome Measures :
  1. Grade II-IV acute GVHD between the 2 groups [ Time Frame: 180 days after HCT ]

Secondary Outcome Measures :
  1. Hematopoietic (whole blood and T cell chimerism) engraftment and incidence of graft rejection in the 2 groups. [ Time Frame: 1 year after HCT ]
  2. Incidence of grade I-IV and III-IV acute GVHD in the 2 groups [ Time Frame: 180 days after HCT ]
  3. Incidence of chronic GVHD in the 2 groups [ Time Frame: 1 year after HCT ]
  4. Quality and timing of immunologic reconstitution in the 2 groups [ Time Frame: 2 years ]
  5. incidences of bacterial, fungal and viral infections in the 2 groups. [ Time Frame: 1 year after HCT ]
  6. relapse rate, nonrelapse mortality, progression-free survival and overall survival in the 2 groups [ Time Frame: 1 year after HCT ]

Inclusion Criteria:


  1. Diseases

    Hematological malignancies confirmed histologically and not rapidly progressing:

    • MPS not in blast crisis and not with extensive marrow fibrosis,
    • ALL in CR;
    • Multiple myeloma not rapidly progressing;
    • CLL;
    • Non-Hodgkin's lymphoma (aggressive NHL should have chemosensitive disease);
    • Hodgkin's disease with chemosensitive disease.
  2. Clinical situations

    • Theoretical indication for a standard allo-transplant, but not feasible because:

      • Age > 50 yrs;
      • Unacceptable end organ performance;
      • Patient's refusal.
    • Indication for a standard auto-transplant: perform mini-allotransplantation 2-6 months after standard autotransplant.
  3. Other inclusion criteria

    • Male or female; fertile patients must use a reliable contraception method;
    • Age < 75 yrs;
    • Informed consent given by patient or his/her guardian if of minor age.


  • Related to the recipient (sibling, parent or child) or unrelated;
  • Male or female;
  • Any age;
  • 10 of 10 (HLA-A, -B, -C, -DRB1, and -DQB1) HLA allele matched;
  • Weight > 15 Kg (because of leukapheresis);
  • Fulfills criteria for allogeneic PBSC donation according to standard procedures;
  • Informed consent given by donor or his/her guardian if of minor age, as per donor center standard procedures.

Exclusion Criteria:


  • Any condition not fulfilling inclusion criteria;
  • HIV positive;
  • Non-hematological malignancy(ies) (except non-melanoma skin cancer) < 3 years before nonmyeloablative HCT.
  • Life expectancy severely limited by disease other than malignancy;

  • Patient is a fertile man or woman who is unwilling to use contraceptive techniques during and for 12 months following treatment;
  • Patient is a female who is pregnant or breastfeeding;
  • Previous radiation therapy precluding the use of 2 Gy TBI or 8 Gy TLI;


  • Any condition not fulfilling inclusion criteria;
  • Unable to undergo leukapheresis because of poor vein access or other reasons.
