7. Patients must have a Karnofsky score ≥ 70%.

8. Patients must have adequate hepatic function as evidenced by bilirubin ≤ upper limit of normal (ULN), unless felt to be related to Gilbert's syndrome or hemolysis; patients must also have AST and ALT ≤ 1.5 x ULN and alkaline phosphatase ≤ 2.5 x ULN.

9. Patients must have an estimated or measured creatinine clearance ≥ 30 ml/min/1.73 m2 by the Cockcroft-Gault equation.

10. Patients must have left ventricular ejection fraction ≥ 50%.

11. Patients must have forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and diffusing capacity corrected for hemoglobin (DLCOc) ≥ 50% of predicted.

12. Patients must have recovered from the effects of any prior chemotherapy, radiotherapy or surgery; for patients who have been on monoclonal antibody therapy, at least one half-life or 4 weeks (whichever is longer) should have elapsed prior to the first scheduled day of dosing with FE 203799.

13. A female recipient of childbearing potential must meet the following criteria:

1. Participant has a negative pregnancy test at Screening.

2. Participant agrees to use one of the accepted contraceptive regimens from at least 14 days prior to the first administration of the Study Drug, during the study and for at least 90 days after the last dose of the Study Drug. An acceptable method of contraception includes one of the following:

14. A male patient, with sexual partners who are pregnant, possibly pregnant, or who could become pregnant, agrees to use one of the accepted contraceptive regimens throughout the entire duration of the study and until at least 3 months after the last drug administration. An acceptable method of contraception includes one of the following:

1. Patient is unable or unwilling to give informed consent.

2. Patients who are unable to comply with the treatment protocol including appropriate supportive care, follow-up and tests.

3. Patients with known hypersensitivity to FE 203799, or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions to any drugs.

4. Patients with an active infection or with a fever ≥38.5oC within 3 days of the first scheduled day of dosing.

5. Patients who had an autologous stem cell transplant within 24 months.

6. Patients who had an available cryopreserved autologous graft with a CD34+ cell count of < 2 x 106/kg.

7. Patients undergoing AHSCT for conditions other than lymphoma.

8. Presence of a malignancy other than the one for which the transplant is being performed (except for baso-cellular skin carcinoma).

9. Patients who are receiving investigational therapies or who have been treated with investigational therapies or investigational devices within 30 days prior to the first scheduled day of dosing with FE 203799.

10. Patients with cardiovascular congestive heart failure, unstable angina pectoris, cardiac arrhythmias requiring a pacemaker; myocardial infarction within the past six months; stroke within the past 6 months; or uncontrolled hypertension.

11. Patients with mean QTcF values of >450 msec (in males) or >470 msec (in females) following ECGs conducted in triplicate 5 minutes apart from each other; patients who are known to have congenital prolonged QT syndromes, including patients who are already on medication known to cause prolonged QT intervals on ECG.

12. Presence of out-of-range cardiac interval (PR < 110 msec, PR > 220 msec, QRS < 60 msec, QRS >119 msec) on the screening ECG or other clinically significant ECG abnormalities.

13. Patients with history or presence of GI tract cancer, polyps, ulcerative colitis, Crohn's disease, coeliac disease, tropical sprue, etc.

16. Presence of autoimmune disease.

17. Patients with suicidal tendency or clinically relevant psychiatric diseases or substance abuse.

18. Positive results to HIV Ag/Ab Combo, Hepatitis B surface Antigen (HbsAG (B) (hepatitis B)) or anti-Hepatitis C Virus (HCV (C)) tests.
