Study & Design

Study Type
INTERVENTIONAL
Study Design
SINGLE_GROUP
Arm && Interventions
GroupInterventionDescription
LuspaterceptLuspatercept InjectionSingle-arm design: All patients are treated with 1.75 mg Luspatercept per kg body weight subcutaneously on day 1 of each 21 day cycle for up to 24 weeks and in case of response for up to 1.5 years.
Primary Outcome Measures
NameTimeMethod
Erythroid response (HI-E)At the end of cycle 8 (each cycle is 21 days)

To evaluate the proportion of patients who have an erythroid response (HI-E) according to the modified IWG 2018 criteria separately for four different clinical situations (cohorts) distinguished by two factors: Serum erythropoietin (sEPO) level AND Ring sideroblast (RS) status

Secondary Outcome Measures
NameTimeMethod
HI-E response (erythroid response) durationFrom the date of treatment start until date of documented loss of response, assessed up to 18 months.]

To evaluate HI-E response from the first day of response until loss of response.

Platelet (HI-P) responsesAt the end of cycle 8 (each cycle is 21 days)

Platelet (HI-P) responses according to IWG 2018 criteria

Impact of luspatercept on quality of life by using the validated Quality of Life in Myelodysplasia Scale (QUALMS)From the date of treatment start until the end of study, assessed up to 48 months

QoL assessment using the QUALMS questionnaire up to end of treatment:

38-item assessment tool for patients with Myelodysplastic Syndromes (MDS) QUALMS scores ranged from 24 to 99, with higher scores for better outcome

Time to HI-E (erythroid response)From the date of treatment start until first day of response, assessed up to end of cycle 8 (each cycle is 21 days)

To evaluate the time between start of treatment and first day of response.

Neutrophil (HI-N) responsesAt the end of cycle 8 (each cycle is 21 days)

Neutrophil (HI-N) responses according to IWG 2018 criteria

Safety of luspatercept (toxicities and adverse events)From the date of treatment start until the end of study, assessed up to 48 months

Assessments will include characterization of toxicities; characterization of AEs including type, incidence, severity, seriousness, and relationship to treatment

Impact of treatment assessed by using the validated European Organisation for Research and Treatment of Cancer Core Quality of Life questionnaire (EORTC QLQ-C30)From the date of treatment start until the end of study, assessed up to 48 months.

To assess patient-reported quality of life during luspatercept treatment: 30 questions assessing the quality of life of oncology patients across 10 subscales will be analyzed. All subscales have a score range from 0 to 100 points.

Function subscales: a higher score represents a higher quality of life. Symptoms subscales: higher score represents higher level of symptoms/problems, i.e., represents lower quality of life.
