Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPercentage of Participants With ≥ 35% Reduction From Baseline in Spleen Volume at Week 24Baseline, Week 24Reduction in spleen volume is measured by magnetic resonance imaging/computerized tomography (MRI/CT).
SecondaryPercentage of Participants Achieving ≥ 50% Reduction From Baseline in Total System Score (TSS) at Week 24Baseline, Week 24
TSS is assessed by the Myelofibrosis Symptom Assessment Form (MFSAF) version 4.0. Participants complete a symptom diary and rate the following seven MF symptoms: fatigue, night sweats, abdominal discomfort, pruritus, pain under the ribs on the left side, early satiety, and bone pain daily using a scale from 0 (absent) to 10 (worst imaginable), and the scores are averaged over 7 days, with a minimum of 4 days required to calculate the average score. Participants for whom a valid average score cannot be calculated either at baseline or post-baseline are considered non-responders. The TSS reflects the sum of the scores of these symptoms, for a maximum possible score of 70 (i.e., most severe symptom experience).
SecondaryPercentage of Participants Achieving Anemia ResponseUp to 254 weeks
For a participant who is transfusion independent (TI) at Baseline with hemoglobin value \< 10 g/dL, anemia response is achieved if the post-Baseline hemoglobin level increases by ≥2 g/dL without receiving packed red blood cells (PRBC) transfusion (for any reason) within 2 weeks and without any erythropoietin or mimetics within the last 4 weeks prior to the increase in hemoglobin level by ≥2g/dL was observed. Hemoglobin values more than 30 days after the last dose of study treatment or after the start of post-study treatment or disease progression, whichever is earlier, will not be considered in the analysis of anemia response. For a participant who is transfusion dependent (TD) at Baseline, anemia response is defined as a period of at least 12 consecutive weeks without PRBC transfusion at any time after the first dose of study drug and on or prior to 30 days post last dose of study drug, the start of post-study treatment, disease progression or death, whichever occurs earlier.
SecondaryPercentage of Participants With ≥ 1 Grade Reduction From Baseline in Fibrosis Grade At Any TimeUp to 254 weeks
Bone marrow grading is assessed according to the European Consensus Grading System. The 4-point grading scale ranges from MF-0, which corresponds to normal bone marrow, to MF-3, diffuse and dense increase in reticulin with extensive intersections with coarse bundles of collagen, often associated with significant osteosclerosis.
SecondaryTime to First Reduction in Fibrosis GradeUp to 254 weeks
Grade of bone marrow fibrosis was assessed by investigators according to the European Consensus Grading System. The 4-point grading scale ranges from MF-0, which corresponds to normal bone marrow, to MF-3, diffuse and dense increase in reticulin with extensive intersections with coarse bundles of collagen, often associated with significant osteosclerosis. The time to first achieving a reduction of at least 1 grade in bone marrow fibrosis from Baseline was summarized.

Full Analysis Set (FAS): all participants who take at least one dose of navitoclax; participants who were Baseline transfusion independent with baseline hemoglobin of ≥10 g/dL were excluded from the analysis since they were not evaluable for anemia response. Missing post-Baseline anemia response in Full Analysis Set applicable to evaluation of anemia response are considered as non-responders of anemia response.
