NCT05282459 · STUDY IN CONTEXT

Enasidenib in MDS &Non-proliferative Chronic Myelomonocytic Leukemia w/o IDH2 Mutation

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

primary · POSTED

Clinical response was assessed as the number of participants achieving a hematological improvement - erythroid (HI-E). Participants were characterized and stratified as nontransfused (NTD), low-transfusion burden (LTB) and high-transfusion burden (HTB), with response defined as follows. * NTD = greater than or equal to 2 consecutive Hb measurements, greater than or equal to 1.5 g/dL for a period of minimum 8 week in an observation period of 16 to 24 week compared to the lowest mean of 2 Hb measurements * LTB = 0 units of RBC transfusions * HTB = greater than or equal to 4 unit or greater than or equal to 50% reduction in RBC transfusions

Source null

secondary · POSTED

Toxicity was assessed as the number of related non-serious adverse events and related serious adverse events (SAEs) reported by dose level (Cohort A or Cohort B) for the 12-cycle treatment period plus follow-up.

Source null

→

secondary · POSTED

Time to hematological improvement - erythroid (HI-E) was assessed as the time from first dose of enasidenib to the first observed hemoglobin response. Participants will be characterized and stratified as non-transfused (NTD), low-transfusion burden (LTB) and high-transfusion burden (HTB), with response defined as follows. * NTD = greater than or equal to 2 consecutive Hb measurements, greater than or equal to 1.5 g/dL for a period of minimum 8 week in an observation period of 16 to 24 week compared to the lowest mean of 2 Hb measurements * LTB = 0 units of RBC transfusions * HTB = greater than or equal to 4 unit or greater than or equal to 50% reduction in RBC transfusions

No participants achieved Hematological Improvement - Erythroid (HI-E), and therefore no results could be calculated.

secondary · POSTED

Duration of Hematological Improvement - Erythroid (HI-E) will be assessed as the time from recorded response to loss of response. Participants will be characterized and stratified as nontransfused (NTD), low-transfusion burden (LTB) and high-transfusion burden (HTB), with response defined as follows. NTD = greater than or equal to 2 consecutive Hb measurements, greater than or equal to 1.5 g/dL for a period of minimum 8 week in an observation period of 16 to 24 week compared to the lowest mean of 2 Hb measurements LTB = 0 units of RBC transfusions HTB = greater than or equal to 4 unit or greater than or equal to 50% reduction in RBC transfusions The outcome will be reported as the number of participants that achieve the response, a number without dispersion.

No participants achieved Hematological Improvement - Erythroid (HI-E), and therefore no results could be calculated.

secondary · POSTED

Clinical response for platelets was assessed as the number of participants achieving a hematological improvement - platelets (HI-P). Participants will be characterized and stratified as platelets \< or ≥ 20 x 10\^9/L, with response defined as follows. * \< 20 x 10\^9/L = increase in platelets from \< 20 x 10\^9/L to \> 20 x 10\^9/L AND by ≥ 100% * ≥ 20 x 10\^9/L = absolute increase in platelets of 30 x 10\^9/L The outcome will be reported as the number of participants that achieve the response, a number without dispersion.

Source null

secondary · POSTED

Clinical response for neutrophils was assessed as the number of participants achieving a hematological improvement - neutrophils (HI-N). Response was defined as an absolute increase in neutrophils \> 0.5 × 10\^9/L that was also an increase of ≥ 100%.
