This is an interventional treatment trial for Hematological Malignancies Read More

Inclusion Criteria:

1. Signed written informed consent.
2. Age > 18 or < 55.

3. Patients with AML, ALL, or other haematological malignancies with an indication to transplant with or without a matched donor undergoing allogenic haploidentical hematopoietic transplantation (see Appendix 2) in any of the following categories:

   • Patients in first complete remission (CR) at high risk of relapse because of unfavourable cytogenetics, such as:

     • t (9;22)
     • 11q23 translocation
     • complex karyotype
     • t (8;12)/ETV6-AML
     • t (6;9)/DEK-CAN
     • t (11;14)(q15,q11)
     • Trisomy 13
     • FLT-3/ITD

   • Or other adverse prognostic factors, such as:

     • Secondary leukemia
     • CR after second line treatment
     • High blast count
     • Biphenotypic leukemia
   • Patients in 2nd or 3rd CR or in chemoresistant relapse
4. Recipient CMV positive as measured by pp65 antigenemia and PCR
5. Adequate cardiac function: Asymptomatic of if symptomatic then left ventricular ejection fraction at rest be >45% and must improve with exercise,
6. Adequate hepatic function: <2 x GOT and GPT and <2.0 mg total serum bilirubin unless liver is involved in disease,
7. Adequate renal function: Serum creatinine within normal range or if serum creatinine outside normal range then creatinine clearance >50 ml/min,
8. Adequate Pulmonary function: Diffusion capacity >50% of predicted (corrected for hemoglobin)
9. Normal TSH or evidence of proper thyroid hormone replacement.
10. For women of childbearing potential participating in the study, abstinence from sexual intercourses or use of a reliable form of effective contraception during the treatment period. These may include, but are not limited to, birth control pills, IUDs, condoms, diaphragms, implants, surgical sterilization, or being in a post-menopausal state.

2. HIV positive
3. Presence of any other active, uncontrolled bacterial, viral or fungal infection
4. Neurological or psychiatric dysfunctions which would impair compliance with the medical regimens and/or transplantation toleration
5. Concomitant or prior history of malignancy other than surgically cured in situ carcinoma of the cervix.
6. Pregnancy as documented by a urine pregnancy test or lactation.
7. Any indication that the patient would not comply with the conditions of the study protocol.
8. Previous treatment with thymosin alpha 1.
9. Simultaneous participation in another investigational drug study or participation in any clinical trial involving investigational drugs within 3 months before study entry.
