Tamibarotene Plus Azacitidine in Participants With Newly Diagnosed RARA-positive Higher-Risk Myelodysplastic Syndrome

Phase 3
Terminated
Conditions
Myelodysplastic Syndromes
Interventions
Registration Number
NCT04797780
Lead Sponsor
Syros Pharmaceuticals
Brief Summary

This study compares the efficacy of Tamibarotene in combination with azacitidine to azacitidine in combination with placebo in participants who are Retinoic Acid Receptor Alpha (RARA) positive, and newly diagnosed with higher-risk myelodysplastic syndrome (HR-MDS), and who have not received treatment for this diagnosis. The primary goal of the study is to compare the complete remission rate between the two treatment arms.

Detailed Description

A subset of participants have MDS characterized by an overexpression of the RARA gene. A blood test will be used to identify participants with RARA-positive MDS. Assessment of the RARA biomarker for study eligibility will be done by collection of blood samples from potential study participants at the pre-screening visit and testing at a central laboratory. Participants who meet eligibility requirements will be randomized 2:1 to receive either Tamibarotene plus azacitidine or placebo plus azacitidine.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Complete Remission (CR)Up to 45 months

Time to Complete Remission (TCR)Up to 45 months

TCR was defined as the duration from the date of randomization to the date of the first documented evidence of CR as determined by the investigator per the modified IWG MDS criteria. Among CR responders, this outcome measure was calculated as: Time to CR= (date of the first documented evidence of CR - date of randomization + 1) / 30.4375.

Change in Health-Related Quality of Life (HRQoL) as Assessed by the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 Scale (EORTC QLQ-30)Up to 45 months

HRQoL was evaluated by EORTC QLQ-C30 global health status/quality of life composite scale in all randomized participants. The QLQ-30 is a cancer-specific, self-administered questionnaire that contains 30 questions, covering global, functional, and symptom scales. Scores range from 0 to 100. Higher scores on global and functional scales indicated better quality of life (QoL), while higher scores on the symptom scales indicated declining QoL.

Change in HRQOL as Assessed by the European Quality of Life 5 Dimensions Scale (EuroQoL-5D)Up to 45 months

The EQ-5D-3L essentially consisted of- the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D-3L descriptive system comprised of the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension had 3 levels: no problems, some problems, extreme problems. Total scale range for each dimension reported was 1 to 3. The EQ VAS recorded the respondent's self-rated health on a vertical, visual analogue scale where the endpoints are labelled 'Best imaginable health state' and 'Worst imaginable health state'. This information can be used as a quantitative measure of health outcome as judged by the individual respondents. Total scale range for VAS dimension reported was 0 to 100.

Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)Up to 45 months

An AE was defined as any untoward medical occurrence that developed or worsened in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. TEAEs are defined as those AEs with onset after the first dose of study drug or existing events that worsened after the first dose during the study up until the last dose of study drug + 30 days. SAEs included death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized the participant and required medical intervention to prevent 1 of the outcomes listed in this definition. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
