Clinical Trial Summary

The purpose of this study is to determine the safety of and to select a treatment regimen of pomalidomide (CC-4047) either as single-agent or in combination with prednisone to study further in patients with myelofibrosis with myeloid metaplasia (MMM).


Description:

Participants received study treatment in the Double Blind Treatment Phase for up to 12 cycles (336 days; 12 cycles of 28 days each). Participants who completed the Double-Blind Treatment Phase were unblinded and, if receiving pomalidomide and determined to have a complete remission (CR), partial remission (PR) or clinical improvement (CI) using the International Working Group (IWG) Response Criteria in the study protocol, could have continued on their current dose of pomalidomide until disease progression. Participants receiving placebo were discontinued from the study.

Exclusion Criteria:

- Previous untoward reaction to corticosteroid (specifically, prednisone) therapy that was severe enough, in the opinion of the treating physician, to preclude study participation.

- The use of any growth factors, cytotoxic chemotherapeutic agents (e.g. hydroxyurea and anagrelide), corticosteroids, or experimental drug or therapy within a minimum of 28 days of starting CC-4047 and/or lack of recovery from all toxicity from previous therapy to grade 1 or better (e.g. alpha interferon may require 84 days of longer or washout).

- Prior therapy with CC-4047 or, lenalidomide or thalidomide for Myelofibrosis with myeloid metaplasia (MMM). (Prior prednisone use as a therapy for MMM is allowed, but not within 28 days of starting CC-4047).

- History of deep vein thrombosis or pulmonary embolism within one year of starting study medication.

- Any serious medical condition or psychiatric illness that would prevent, (as judged by the treating physician) the subject from signing the informed consent form or any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.

- Pregnant or lactating females

Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Participants With a Clinical Response Within the First 6 Cycles of Treatment A clinical responder was defined as either:
A baseline red blood cell (RBC)-transfusion-dependent participant with a = 56 consecutive day RBC transfusion-free period after the first dose of study drug, or
A baseline RBC-transfusion-independent participant with an increase in hemoglobin of 2.0 g/dL or more from baseline for = 56 consecutive days in the absence of RBC transfusions, or
A participant with either a = 50% reduction in palpable splenomegaly of a spleen that was = 10 cm at baseline or a spleen that was palpable at > 5 cm and became not palpable.
Participants who discontinued the study early without achieving clinical response were counted as non-responders.
Up to 168 days
Secondary Percentage of Participants With a Clinical Response Within the First 12 Cycles of Treatment A clinical responder was defined as either:
A baseline red blood cell (RBC)-transfusion-dependent participant with a = 56 consecutive day RBC transfusion-free period after the first dose of study drug, or
A baseline RBC-transfusion-independent participant with an increase in hemoglobin of 2.0 g/dL or more from baseline for = 56 consecutive days in the absence of RBC transfusions, or
A participant with either a = 50% reduction in palpable splenomegaly of a spleen that was = 10 cm at baseline or a spleen that was palpable at > 5 cm and became not palpable.
Participants who discontinued the study early without achieving clinical response were counted as non-responders.
Up to 336 days
Secondary Time to the First Clinical Response The time to the first clinical response achieved within 168 days after the first study drug dosing date was calculated for participants who achieved a clinical response as:
Start date of the first clinical response - the first study drug date +1.
A clinical responder was defined as either:
A baseline red blood cell (RBC)-transfusion-dependent participant with a = 56 consecutive day RBC transfusion-free period after the first dose of study drug, or
A baseline RBC-transfusion-independent participant with an increase in hemoglobin of 2.0 g/dL or more from baseline for = 56 consecutive days in the absence of RBC transfusions, or
A participant with either a = 50% reduction in palpable splenomegaly of a spleen that was = 10 cm at baseline or a spleen that was palpable at > 5 cm and became not palpable.
Up to 168 days
Secondary Duration of First Clinical Response For RBC-transfusion-dependent patients, duration of response was calculated as the last day of response - first day of response +1, where the last day of response was the date of the first RBC-transfusion administrated at or more than 56 days after the response started. For patients who did not receive a subsequent transfusion after the response started, the end date of response was censored at the day of last hemoglobin assessment.
For RBC-transfusion-independent patients, the duration of response was calculated as the last day of response - first day of response +1, where the last day of response was the earlier of the date of a hemoglobin increase of < 2.0 g/dL and the date of a RBC transfusion at = 56 days after the response started. For patients whose hemoglobin measurements were always = 2.0 g/dL and never received a RBC transfusion after response started, the end date of the response was censored at the date of last hemoglobin measurement.
Kaplan-Meier methodology was used.
Up to 40 months
Secondary Change From Baseline in Functional Assessment of Cancer Therapy-Anemia (FACT-An) Subscale and Total Scores The FACT-An comprises the four subscales of the 27-item FACT-General Scale (FACT-G), Physical Well-being, Social/Family Well-being, Emotion Well-being, Functional Well-Being, and the Additional Concerns Anemia subscale. Questions are rated on a scale from 0 to 4, where higher scores indicate more impact on quality of life.
Physical Well-being consists of 7 questions, the subscale score ranges from 0-28;
Social/Family Well-being consists of 7 questions, the subscale score ranges from 0-28;
Emotion Well-being consists of 6 questions, the subscale score ranges from 0-24;
Functional Well-Being consists of 7 questions, the subscale score ranges from 0-28;
Anemia subscale consists of 20 questions, the subscale score ranges from 0-80;
Total FACT-An score ranges from 0-188.
Baseline and Cycle 6 (168 days).
Secondary Change From Baseline in Hemoglobin Concentration for Responders Change from Baseline in hemoglobin for participants with a clinical response within the first 6 cycles of treatment. Baseline, Cycle 6 (168 days)
Secondary Change From Baseline in Hemoglobin Concentration for Non-Responders Change from Baseline in hemoglobin for participants without a clinical response within the first 6 cycles of treatment. Baseline, Cycle 6 (168 days)
Secondary Change From Baseline in Likert Abdominal Pain Scale Participants rated abdominal discomfort or pain over the previous week on a scale from zero to ten, where zero is no discomfort or pain and ten is the worst pain imaginable. Baseline and Cycle 6 (168 days)
Secondary Percentage of Participants With Clinical Response by Baseline JAK2 Assessment Percentage of participants who achieved a clinical response, presented by participants with positive and negative janus kinase 2 (JAK2) V617F mutation results at Baseline. Up to 336 days
Secondary Number of Participants With Adverse Events (AEs) A serious AE (SAE) was defined as any AE which resulted in death or was life-threatening, required or prolonged inpatient hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or constituted an important medical event (events that may have jeopardized the patient or required intervention to prevent one of the outcomes listed above).
The severity of AEs were graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE, Version 3.0) or according to the following scale:
Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Life-threatening; Grade 5 = Death.
The Investigator determined the relationship between study drug and the occurrence of an AE as "Not Related" or "Related" (since the study was double-blinded, a patient receiving only prednisone could have an AE that was judged as related to pomalidomide, and vice-versa).
From date of the first dose of the study drug until discontinuation or the data cut-off date (up to approximately 45 months).
