Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Safety, Efficacy
To find the MTD of Venetoclax when added to Fludarabin, Amsacrine and Ara-C + Treosulfan and evaluate , whether the addition of Venetoclax to sequential conditioning with Fludarabine + Amsacrine + Ara-C (FLAMSA) + Treosulfan for allogeneic blood stem cell transplantation in patients with high-risk MDS, CMML or sAML (FLAMSAClax) is safe
Secondary objectives 3
- To assess incidence, course und severity of aGvHD and cGvHD as well as incidence, course and severity of VOD and graft failure, time to hematopoietic reconstitution (ANC>500/μl, PLT>20000/μl and PLT>50000/μl) and time to transfusion independence
- To analyse best response within the first 100 days (± 7) after transplantation (according to IWG-criteria for MDS and ELN-criteria for AML) as well as response rates at day +30 (± 3) , +60 (± 7) and +100 (± 7) after transplantation. In detail, time to complete donor chimerism in blood and marrow and disappearance of molecular markers of disease
- To evaluate event-free survival, cumulative incidence of relapse and overall survival

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 1
- MDS, CMML or sAML according to WHO classification (revised version 2016) with a marrow blast count >5% and/or high-risk genetic features (eg. bad risk karyotype according to the IPSS-R / ELN classification or presence of unfavorable somatic mutations (e.g. TP53, RUNX1, IDH1, IDH2, KMT2A, DEK-NUP214 or RAS pathway mutations including NRAS, KRAS, PTPN11, CBL, NF1, RIT1 or KIT), falling into the "high" or "very high" risk category of the IPSS-R or IPSS M) any time between diagnosis and inclusion.
Exclusion criteria 1
- previous cytotoxic therapy exceeding oral Hydroxyurea or >2 courses of treatment with Azacytidine, Decitabine or low dose Ara-C alone or in combination with Venetoclax
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- safety, defined as the maximal organ toxicity to each organ system according to CTC criteria as well as the number of AEs of grade III or greater until day +30 (± 3) after transplantation
Secondary endpoints 13
- safety, defined as the maximal organ toxicity to each organ system according to CTC criteria as well as the number of AEs of grade III or greater until day +100 (± 7) after transplantation
- graft failure defined as no donor chimerism at day +30 (± 3) after transplantation
- incidence, course und severity of aGvHD and cGvHD during the first 2 years after transplantation
- incidence, course and severity of VOD
- time (days from day 0) to hematopoietic reconstitution (ANC>500/µl, PLT>20000/µl and PLT>50000/µl)
- time (days from day 0) to transfusion independence
- best disease response within the first 100 days (± 7) after transplantation (according to IWG-criteria for MDS and ELN-criteria for AML)
- disease response and donor chimerism at day +30 (± 3), +60 (± 7) and +100 (± 7) after transplantation (according to IWG-criteria for MDS and ELN-criteria for AML)
- time (days from day 0) to complete donor chimerism in blood and marrow
- disappearance of molecular markers of disease (yes/no, time in days from day 0 )
- event-free survival (EFS, death, relapse and disease progression will be recorded as event)
