Study Details

Study Description

Brief Summary

There are currently no licensed drugs in the EU to treat thrombocytopenia in MDS patients classified as IPSS low/int-1. Prior studies with romiplostim (a TPO receptor agonist) in MDS found that baseline concentration of TPO as well as transfusion history were predictive of subsequent response in a retrospective model. The current prospective study has the aim to explore whether both pretreatment variables (endogenous TPO, TPO-level, platelet transfusion history) can predict the response to subsequent short-term treatment with romiplostim.

Condition or Disease Intervention/Treatment Phase
  • Drug: N-Plate / romiplostim
Phase 2

Detailed Description

Myelodysplastic syndromes (MDS) are a heterogeneous group of hematologic malignancies of the pluripotent hematopoietic stem cells characterized by clonal hematopoiesis, progressive bone marrow failure, and the propensity to transform to acute myeloid leukemia (AML) (Malcovati et al., 2013).

There are currently no licensed drugs in the EU to treat thrombocytopenia in MDS patients classified as IPSS low/int-1. Prior studies with romiplostim (a TPO receptor agonist) in MDS found that baseline concentration of TPO as well as transfusion history were predictive of subsequent response in a retrospective model.

Classically, MDS is associated with apoptosis and excessive proliferation, resulting in a combination of a hyper-cellular marrow and peripheral cytopenia. The rationale for using romiplostim in MDS is to stimulate normal progenitor cells to increase platelet counts. Upon correction of thrombocytopenia, responding MDS patients should have a decreased risk of bleeding and a reduction in platelet transfusions (Giagounidis et al., 2014). This reduction in platelet transfusions may in turn decrease the risks of alloimmunization and the resultant morbidity and costs associated with that condition.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Group 1

Stratification into group 1 if Score (Baseline-TPO Level and previous thrombocyte transfusions) are +3 TPO based model to predict subsequent response to romiplostim in MDS patients with IPSS Low/Int-1 according to a model developed by Sekeres et. al./ BJH 2014

Drug: N-Plate / romiplostim
medical intervention in 3 patient groups (MDS patients with IPSS Low/Int-1) that are stratified according to their baseline TPO-Level and previous transfusions

Experimental: Group 2

Stratification into group 2 if Score (Baseline-TPO Level and previous thrombocyte transfusions) are -1 or -2 TPO based model to predict subsequent response to romiplostim in MDS patients with IPSS Low/Int-1 according to a model developed by Sekeres et. al./ BJH 2014

Drug: N-Plate / romiplostim
medical intervention in 3 patient groups (MDS patients with IPSS Low/Int-1) that are stratified according to their baseline TPO-Level and previous transfusions

Experimental: Group 3

Stratification into group 3 if Score (Baseline-TPO Level and previous thrombocyte transfusions) are -6 TPO based model to predict subsequent response to romiplostim in MDS patients with IPSS Low/Int-1 according to a model developed by Sekeres et. al./ BJH 2014

Drug: N-Plate / romiplostim
medical intervention in 3 patient groups (MDS patients with IPSS Low/Int-1) that are stratified according to their baseline TPO-Level and previous transfusions

Outcome Measures

Primary Outcome Measures

  2. The incidence of disease progression to higher stage MDS or AML [up to 12 months]

  3. Increase of peripheral blasts during therapy [up to 12 months]

  4. Association of the presence of certain mutations with disease progression in a retrospective analysis [up to 12 months]

  5. Incidence of bleeding events [up to 12 months]

  6. Type, incidence and severity of all adverse events including clinically significant changes in laboratory values [up to 12 months]

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years and Older
Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  • Subjects must meet the following inclusion/exclusion criteria to be eligible for the study.

  • Must understand and voluntarily sign the informed consent form

  • Age older 18 years at the time of signing the informed consent form

  • Must be able to adhere to the study visit schedule and other protocol requirements

  • Diagnosis of MDS using the 2008 WHO classification for myeloid neoplasms as assessed during the screening period

  • Per MDS IPSS, low or intermediate-1 risk MDS as assessed during the screening period

  • The mean of the 2 platelet counts taken within 4 weeks prior to stratification must be:

  • ≤ 30 x 109/L (with no individual count > 30 x 109/L during the screening period), with or without a history of bleeding associated with the diagnosis of MDS, OR

  • < 50 x 109/L (with no individual count >60 x 109/L during the screening period), with a history of bleeding associated with the diagnosis of MDS (A standard of care platelet count taken prior to Informed consent may be used as 1 of the 2 counts taken within 4 weeks prior to stratification)

  • Adequate liver function, as evidenced by ALT ≤ 3 times the laboratory normal range, AST ≤ 3 times the laboratory normal range and total bilirubin ≤ 2 times the laboratory normal range

  • Bone marrow aspirate (central diagnostics) with cytogenetics (local) within 8 weeks of starting first dose of investigational product

  • Female subjects of childbearing potential† must:

  • Agree to use, and be able to comply with, effective contraception without interruption, 4 weeks before starting study drug, throughout study drug therapy and for 4 weeks after the end of study drug therapy, even if she has amenorrhoea. This applies unless the subject commits to absolute and continued abstinence confirmed on a monthly basis. Male patients who wish to participate in the study and their partner may become pregnant must agree also to reliable contraception during the study and for three months thereafter.

The following are effective methods of contraception*

  • Implant, - Levonorgestrel-releasing intrauterine system (IUS), Medroxyprogesterone acetate depot, Tubal sterilization, Sexual intercourse with a vasectomised male partner only; Ovulation inhibitory progesterone-only pills (i.e., desogestrel)

  • Agree to have a medically supervised pregnancy test with a minimum sensitivity of 25 mIU/ml not more than 3 days before the start of study medication once the subject has been on effective contraception for at least 4 weeks. This requirement also applies to women of childbearing potential who practice complete and continued abstinence.

Exclusion Criteria:
  • Pregnant or lactating females

  • IPSS intermediate-2 or high-risk

  • ≥ 5% blasts in the bone marrow as determined by central morphology during screening

  • Previous treatment with any thrombopoietic growth factor

  • Prior history of hematopoietic stem cell transplantation, leukemia, aplastic anemia or other non-MDS related bone marrow stem cell disorder

  • History of arterial thrombosis (e.g., stroke or transient ischemic attack) within the past year

  • History of venous thrombosis that currently requires anti-coagulation therapy

  • Prior use of sc or iv AZA.
