Brief summary

The objective of the phase I part of the trial is the determination of the maximum tolerated dose (MTD) of TCP (Tranylcypromine) in combination with fixed-dose ATRA (all-trans-retinoic acid) and with fixed-dose AraC (Cytarabine) and to derive the recommended phase II dose (RP2D) in patients with non-APL AML or MDS for whom no standard treatment is available or who failed azanucleoside treatment. The objective of the phase II part of the trial is a first evaluation of the efficacy of TCP at the RP2D in combination with fixed-dose ATRA and with fixed-dose AraC as basis for further investigations of TCP

Detailed description

Study treatment: TCP + ATRA + AraC Four dose levels of TCP (20 mg, 40 mg, 60 mg, 80 mg on days 1-28) will be examined in combination with fixed dose ATRA (45 mg/m2 on days 10-28) and fixed-dose AraC (40 mg on days 1-10) in the first cycle. In further cycles patients will be treated in the same manner, except for ATRA which will be administered continuously with a nine-day interruption at the beginning of every fourth cycle. Follow-up per patient: Until twelve months after registration of the last patient. Duration of intervention per patient: Until relapse/progression, unacceptable toxicity or until twelve months after registration of the last patient, whatever occurs first

Interventions

TCP p.o., daily either 20, 40\*\*, 60\*\*, 80\*\* mg/day, (28d/cycle) \*\*TCP doses will be slowly increased during cycle 1 and slowly decreased at end of treatment (for details see study protocol)

DRUGall-trans retinoic acid

45mg/m2 (days 10-28), CAVE: ATRA will be administered without interruption until inclusively cycle 3. At the beginning of the cycle 4 a nine-day break corresponding to the first nine days of the AraC treatment will be performed, thereafter the ATRA-therapy will be continued with a nine-day interruption every fourth cycle. That means that the therapy in cycles 1, 4, 7, 10, 13 etc. In other cycles ATRA will be given without interruption

DRUGcytarabine

40mg s.c. (days 1-10)
