Phase 1: Number of Adverse Events and Serious Adverse Events as Assessed by CTCAE Criteria
Ramy czasowe: Up to approximately 6 months
The distribution of adverse events was performed through the analysis of frequencies for treatment-emergent adverse events (TEAEs) and serious adverse events (TESAEs), based on the monitoring of relevant clinical and laboratory safety parameters. Treatment-emergent adverse events (TEAEs) in this study were defined as events that began after the first dose of study treatment and continued until 30 days after the last dose, or events that were present prior to the first dose and increased in severity based on preferred term within 30 days following the last dose of pelabresib (CPI-0610).
Up to approximately 6 months
Phase 2 (All Arms): Number of Adverse Events and Serious Adverse Events as Assessed by CTCAE Criteria
Ramy czasowe: Up to approximately 387 weeks
The distribution of adverse events was performed through the analysis of frequencies for treatment-emergent adverse events (TEAEs) and serious adverse events (TESAEs), based on the monitoring of relevant clinical and laboratory safety parameters. Treatment-emergent adverse events (TEAEs) in this study were defined as events that began after the first dose of study treatment and continued until 30 days after the last dose, or events that were present prior to the first dose and increased in severity based on preferred term within 30 days following the last dose of pelabresib (CPI-0610).
Up to approximately 387 weeks
Phase 2 (All Arms): Symptom Improvement From the Patient Global Impression of Change (PGIC) at 12 and 24 Weeks
Ramy czasowe: Week 12 (Cycle 5 Day 1), Week 24 weeks (Cycle 9 Day 1)
The Patient Global Impression of Change (PGIC) was a single-question, patient-reported assessment that asked individuals to rate their overall change in myeloproliferative neoplasm (MPN) symptoms since starting study treatment. The participants selected one of seven options, ranging from 'Very much improved' to 'Very much worse'. 'No Change from Baseline' indicated stable symptoms (no improvement or worsening), negative change from Baseline indicated a reduction in symptom severity (improvement), and positive change from Baseline indicated an increase in symptom severity (worsening).
Week 12 (Cycle 5 Day 1), Week 24 weeks (Cycle 9 Day 1)
Phase 2 (Arms 1, 2 and 3): Percent Change From Baseline in Total Symptom Score (TSS) From the Myelofibrosis Symptom Assessment Form (MFSAF v4.0) at 12 and 24 Weeks
Ramy czasowe: Baseline, Week 12 (Cycle 5 Day 1), Week 24 (Cycle 9 Day 1)
The MFSAF (Myelofibrosis Symptom Assessment Form) was completed by participants every day for 7 days before Day 1 of each treatment cycle, including the 7 days before starting Cycle 1. It used a 24-hour recall format, asking participants to rate the worst severity of seven symptoms (fatigue, night sweats, pruritus, abdominal discomfort, pain under the ribs on the left side, early satiety, and bone pain) during the past 24 hours. Each symptom was rated on a scale from 0 (Absent) to 10 (Worst Imaginable). The Total Symptom Score (TSS) was the sum of 7 symptoms (range: 0-70). 'No Change from Baseline' indicated stable symptoms (no improvement or worsening), negative change from Baseline indicated a reduction in symptom severity (improvement), and positive change from Baseline indicated an increase in symptom severity (worsening).
Baseline, Week 12 (Cycle 5 Day 1), Week 24 (Cycle 9 Day 1)
Phase 2 (Arms 1, 2 and 3): Number of Participants Who Achieved a ≥ 50% Reduction in Total Symptom Score (TSS) at 12 and 24 Weeks
Ramy czasowe: Week 12 (Cycle 5 Day 1), Week 24 (Cycle 9 Day 1)
The proportion of study participants who experienced a reduction of at least 50% in their Total Symptom Score (TSS), as assessed using the Myelofibrosis Symptom Assessment Form (MFSAF v4.0), was evaluated at both 12 and 24 weeks relative to their baseline score.
Week 12 (Cycle 5 Day 1), Week 24 (Cycle 9 Day 1)
Phase 2 (Arms 1, 2 and 3): Number of Participants With Overall Splenic Response Rate (Overall SVR35)
Ramy czasowe: Through Phase II completion, an average of 6 years
Overall Splenic Response Rate (SVR35) was defined as the proportion of participants who achieved a reduction of at least 35% in spleen size from baseline, as measured by imaging (MRI or CT), at any point between Cycle 1 Day 1 and the End of Study Visit, whichever occurred first.
Through Phase II completion, an average of 6 years
Phase 2 (Arms 1, 2 and 3): Duration of Overall Splenic Response (Overall SVR35)
Ramy czasowe: From first onset of splenic response until loss of response, assessed up to approximately 6 years
Duration of Overall Splenic Response (overall SVR35) was defined as the time from the first occurrence of a at least 35% reduction in spleen volume from baseline until the earliest of the following: a reduction of less than 35% from baseline combined with an increase of more than 25% from the nadir in spleen volume (as measured by MRI or CT), or death. The nadir was defined as the lowest spleen volume recorded after baseline and up to the evaluation point at which the initial splenic response was achieved.
From first onset of splenic response until loss of response, assessed up to approximately 6 years
Phase 2 (Cohorts 1A and 2A): Number of Participants With Splenic Response Rate (SVR35) at 12 and 24 Weeks
Ramy czasowe: Week 12 (Cycle 5 Day 1), Week 24 weeks (Cycle 9 Day 1)
Splenic Response Rate (SVR35) at 12 and 24 weeks was defined as the proportion of participants who achieved a reduction of at least 35% in spleen size from baseline, as determined by imaging (MRI or CT), following 12 and 24 weeks of treatment, respectively.
Week 12 (Cycle 5 Day 1), Week 24 weeks (Cycle 9 Day 1)
Phase 2 (Cohorts 1A and 2A): Duration of Red Blood Cell (RBC) Transfusion Independence (TI) in Participants Who Enroll as Transfusion Dependent (TD)
Ramy czasowe: From first onset of TI to earliest onset of loss of TI, assessed up to approximately 6 years
Duration of Red Blood Cell (RBC) Transfusion Independence (TI) was defined as the longest continuous period during which participants, having achieved at least 12 weeks of transfusion independence, remained free from RBC transfusions.
From first onset of TI to earliest onset of loss of TI, assessed up to approximately 6 years
Phase 2 (Cohorts 1A and 2A): Early Anemic Response Rate in Participants Who Enroll as Transfusion Dependent (TD)
Ramy czasowe: Through Phase II completion, an average of 6 years
Early anemic response rate was defined as the proportion of participants who achieved an average increase of at least 1 g/dL in hemoglobin concentration over any rolling 8-week (56-day) period following baseline. This calculation was performed after applying the 14/3 day rule, which stipulates that hemoglobin measurements must be spaced at least 14 days apart, and that at least 3 such measurements are required within the 8-week window to ensure a reliable average. Importantly, this increase had to occur without any red blood cell (RBC) transfusions during the treatment period and up to the time of the latest hemoglobin assessment for each patient.
Through Phase II completion, an average of 6 years
Phase 2 (Cohorts 1B, 2B, and Arm 3): Number of Participants With Splenic Response Rate (SVR35) at 12 Weeks
Ramy czasowe: Week 12 (Cycle 5 Day 1)
Splenic Response Rate (SVR35) at Week 12 was defined as the proportion of participants who achieved a reduction of at least 35% in spleen size from baseline, as measured by imaging (MRI or CT), following 12 weeks of treatment.
Week 12 (Cycle 5 Day 1)
Phase 2 (Cohorts 1B, 2B, and Arm 3): Anemic Response Rate in Participants Who Enroll as Non-transfusion-dependent (Non-TD)
Ramy czasowe: Through Phase II completion, an average of 6 years
Anemic response was defined as a sustained average increase in hemoglobin concentration of at least 1.5 g/dL over any rolling 12-week (84-day) period following baseline. This calculation excluded periods involving red blood cell (RBC) transfusions and was performed after applying the 14/3-day rule for valid hemoglobin assessments. The response had to be maintained through to the most recent available hemoglobin measurement for each patient.
Through Phase II completion, an average of 6 years
Phase 2 (Arm 4): Percentage of Participants Who Achieve a ≥50% Reduction From Baseline in the Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) Total Score
Ramy czasowe: Baseline, 12 weeks (Cycle 5, Day 1), 24 weeks (Cycle 9, Day 1)
The Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) is a patient-reported questionnaire designed to measure symptom burden in participants with myeloproliferative neoplasms (MPNs). Participants rate the severity of several symptoms (such as fatigue, night sweats, itching, abdominal discomfort, bone pain, early satiety, and others) over the past 24 hours. Each symptom is scored on a scale from 0 (absent/as good as it can be) to 10 (worst imaginable/as bad as it can be). The total score is the sum of all individual symptom scores, providing an overall measure of symptom burden. A 50% reduction in the MPN-SAF total score at 12 or 24 weeks means the patient's overall symptom burden has improved by half compared to their baseline (pre-treatment) score.
Baseline, 12 weeks (Cycle 5, Day 1), 24 weeks (Cycle 9, Day 1)
Phase 2 (Arm 4): Partial Hematological Response Rate (PHR)
Ramy czasowe: Over 2 consecutive cycles (rolling window) (1 cycle = 21 days)

Partial Hematological Response Rate (PHR) was defined as the proportion of participants who met the following criteria over two consecutive cycles up to the last administration of study treatment:

  • Platelet count > 400-600 x 10^9/L
  • WBC count within normal range (i.e., ≤ 10 x 10^9/L)
  • Laboratory results confirmed after 1 cycle (after 3weeks)
Over 2 consecutive cycles (rolling window) (1 cycle = 21 days)
Phase 2 (Arm 4): Overall Hematological Response Rate (OHR)
Ramy czasowe: Through Phase II completion, an average of 6 years
Confirmed Overall Hematological Response (OHR) Rate was defined as the proportion of participants with either a confirmed complete or a partial hematological response at any time.
Through Phase II completion, an average of 6 years
Phase 2 (Arm 4): Duration of Overall Hematological Response Rate (OHR)
Ramy czasowe: Through Phase II completion, an average of 6 years
Duration of Overall Hematological Response (OHR) Rate was defined as the time from when the overall hematological response was first met until the time at which the overall hematological response was lost, i.e., the criteria for an overall hematological response (CHR or PHR) were not observed or death occurred, whichever came first.
Through Phase II completion, an average of 6 years
