Female participants using homonal contraceptives should use a barrier method as well.1 Vasectomized partner is a highly effective birth control method provided that partner is the sole sexual partner of the FCBP trial participant and that the vasectomized partner has received medical assessment of the surgical success2 In the context of this guidance sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments.

研究组 & 干预措施
Reduced Intensity Conditioning before Allogeneic Stem Cell Transplantation
Experimental
Patients with AML, MDS/AML or HR-MDS, who have either responded to remission inducing therapy or are intended for upfront transplantion receive conditioning chemotherapy as follows:
IMPs:
- Venetoclax 400 mg abs. day -8 to day -2
- Fludarabine 30 mg/m2 BSA day -6 to day -2
- Treosulfan 10 g/m2 BSA day -4 to day -2
干预措施: RIC regimen (Drug)
结局指标
主要结局
Overall survival (OS)
时间窗: at day 28 after alloHCT
Primary objective of this trial is to evaluate the feasibility and safety of the augmentation of a treosulfanbased RIC regimen for alloHCT in AML, MDS/AML and HR-MDS patients with the Bcl-2-inhibitor Venetoclax. As outlined above, the aim is to increase antileukemic acitiviy without increasing morbidity and mortality in a vulnerable patient collective. This is operationalized by the following primary endpoint: 1\) Overall survival (OS) at day 28 after alloHCT Most adverse events (AEs) due to the IMPs are expected to occur before day 0. Protacted or lateonset toxicities with potentially lethal consequences cannot be ruled out. Therefore, we regard it most suitable to evaluate overall survival at day 28 after alloHCT.
