institutional guidelines for treatment decisions, including assessment of individual
clinical factors such as age, comorbidities, performance status, and donor
availability

- Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2
Minimum age
18 Years

Can healthy volunteers participate?
No
Key exclusion criteria
- Prior exposure to TIM-3 directed therapy at any time. Prior therapy with immune
checkpoint inhibitors (e.g, anti-CTLA4, anti-PD-1, anti-PD-L1, or anti-PD-L2), cancer
vaccines is allowed except if the drug was administered within 4 months prior to
randomization

- Previous first-line treatment for intermediate, high, very high risk myelodysplastic
syndromes (based on IPSS-R) or CMML with any antineoplastic agents including for
example chemotherapy, lenalidomide and hypomethylating agents (HMAs) such as
decitibine and azacitidine. However, previous treatment with hydroxyurea or
leukopheresis to reduce WBC count is allowed prior to randomization.

- Investigational treatment received within 4 weeks or 5 half-lives of this
investigational treatment, whatever is longer, prior to randomization. In case of a
checkpoint inhibitor: a minimal interval of 4 months prior to randomization is
necessary to allow randomization.

- Subjects with Myelodysplastic syndrome (MDS) based on 2016 WHO classification (Arber
et al 2016) with revised International Prognostic Scoring System (IPSS-R) = 3

- Diagnosis of acute myeloid leukemia (AML) including acute promyelocytic leukemia and
extra-medullary acute myeloid leukemia, primary or secondary myelofibrosis based on
WHO 2016 classification (Arber et al 2016)

- Diagnosis of therapy related myeloid neoplasms based on WHO 2016 classification (Arber
et al 2016)

- History of organ or allogeneic hematopoietic stem cell transplant

Other protocol-defined Inclusion/Exclusion Criteria may apply.

Summary
Brief summary
This is a Phase III multi-center, randomized, two-arm parallel-group, double-blind,
placebo-controlled study of MBG453 or placebo added to azacitidine in adult subjects with
intermediate, high or very high-risk myelodysplastic syndrome (MDS) as per IPSS-R, or Chronic
Myelomonocytic Leukemia-2 (CMML-2) who are not eligible for intensive chemotherapy or
hematopoietic stem cell transplantation (HSCT) according to medical judgment by the
investigator.

The purpose of the current study is to assess clinical effects of MBG453 in combination with
azacitidine in adult subjects with IPSS-R intermediate, high, very high risk MDS and CMML-2.
