Eligibility

Inclusion Criteria:

1. Patients with a haematological chemosensitive malignancy indicated for an allogeneic transplantation, but presenting an increased toxicity risk for classical (high-dose busulfan or standard-dose total body irradiation) conditioning therapies (remission

criteria ref. to Appendix L):

• CML in first or subsequent chronic phase
• NHL in 2nd CR/PR, chemosensitive PR after autologous transplantation ; CLL in 2nd or subsequent CR/PR
• Relapsed Morbus Hodgkin (MH) after autologous transplantation
• Multiple Myeloma (MM) stage II and III according to Durie and Salmon
• AML in 2nd CR/PR or high-risk AML in 1st CR/PR

High-risk defined for example by the following:

• Cytogenetics: -5/5q, -7/7q, del(5q), abnormalities of 3q, complex karyotype (> 3 abnormalities), or
• PR after 1 cycle of induction therapy
• ALL in 2nd CR/PR or high-risk ALL in 1st CR/PR

High-risk defined as follows:

• Leukocytes > 3000/µl (B-Linage) or > 100000/µl (T-Linage);
• Pro-B-ALL, pre-T-ALL
• Cytogenetics: t(9;22)/BCR-ABL; t(4;11)/ALL1-AF
• MDS (patients without prior chemotherapy may be included)

2. Availability of an HLA-identical sibling donor (MRD) or HLA-identical unrelated donor

(MUD) or one mismatch (out of the 6 standard markers) sibling donor (1 misMRD):

• HLA-identity defined by the following markers: A, B, DRB1. DQB1 must be recorded.

3. Age > 18 years

4. Karnofsky Index > 80 %

5. Adequate contraception in female patients of child-bearing potential

6. Co-operative behavior of individual patients

7. Written informed consent

Exclusion Criteria:

1. Completely chemotherapy-resistant disease

2. Severe cardiac insufficiency, severe cardio-vascular or other severe concomitant diseases

3. Symptomatic malignant involvement of the CNS

4. Active infectious disease

5. HIV-positive or active hepatitis infection

6. Impaired liver function (Bilirubin > 1.5 x upper normal limit; Transaminases > 3.0 x upper normal limit)

7. Impaired renal function (Creatinine-clearance < 60 ml/min; Serum Creatinine > 1.5 x upper normal limit).

8. Pleural effusion or ascites > 1.0 L

9. Pregnancy or lactation

10. Known hypersensitivity to fludarabine and/or treosulfan
