Brief summary

Anemia in LR-MDS patients

Detailed description

Anemia in non-transfusion dependent (NTD) or transfusion dependent (low or high transfusion burden, LTB/HTB) patients with very low, low or intermediate risk myelodysplastic syndromes

Interventions

Patients will be treated orally with CA-4948 at 300 mg BID (2x200mg) over 4 cycles. One cycle consists of 28 days, 21 of which are treatment days, followed by 7 days off. Patients with erythroid response (HI-E) after 4 cycles who tolerate CA-4948 may continue to receive CA-4948 until loss of HI-E response.

Design outcomes

Primary

MeasureTime frameDescription
Erythroid response (HI-E)At the end of cycle 4 (each cycle is 28 days).To evaluate the proportion of patients who have an erythroid response (HI-E) according to the modified IWG 2018 criteria separately for both independent substudies.

Secondary

MeasureTime frameDescription
Time to HI-E (erythroid response)From the date of treatment start until first day of response, assessed up to end of cycle 4 (each cycle is 28 days).To evaluate the time between start of treatment and first day of response.
Red blood cell (RBC) transfusionsFrom the date of treatment start until the date of end of treatment, assessed up to 30 months.To evaluate frequency of red blood cell transfusions in transfusion dependent patients
Neutrophil (HI-N) responsesAt the end of cycle 4 (each cycle is 28 days).Neutrophil (HI-N) responses according to IWG 2018 criteria
Platelet (HI-P) responsesAt the end of cycle 4 (each cycle is 28 days).Platelet (HI-P) responses according to IWG 2018 criteria
HI-E response (erythroid response) durationFrom the date of treatment start until date of documented loss of response, assessed up to 30 months.To evaluate HI-E response from the first day of response until loss of response.
Number of participants with clinically significant changes of selected laborotory parameters (parameters listed in detailed description)From the date of treatment start until the end of study, assessed up to 30 months.To ensure patient safety, close monitoring is carried and includes the analysis of: transaminases, bilirubin, amylase, lipase, troponin, lactate dehydrogenase, creatine kinase, uric acid, TSH, FT4, urine analysis.
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 30 months.To assess patient-reported quality of life during CA-4948 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.
Impact of treatment assessed by using the validated European Organisation for Research and Treatment of Cancer cancer related fatigue questionnaire (EORTC QLQ- FA12)From the date of treatment start until the end of study, assessed up to 30 months.To assess patient-reported quality of life during CA-4948 treatment: 12 items, with four response categories for each item (coded with values from 1 to 4) will be analyzed. FA12 scores are transformed to the range 0-100: Higher levels indicate greater degrees of fatigue.
Safety of CA-4948 (toxicities and adverse events)From the date of treatment start until the end of study, assessed up to 30 months.Assessments will include characterization of toxicities; characterization of AEs including type, incidence, severity, seriousness, and relationship to treatment
