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