Study summary

This is an open-label, single-arm study of idasanutlin monotherapy in participants with hydroxyurea (HU)-resistant/intolerant Polycythemia vera (PV). The study will include two phases: initial phase and expansion phase. The initial phase will assess the safety and efficacy of idasanutlin monotherapy in ruxolitinib naïve and ruxolitinib-resistant or intolerant patients, respectively. If the initial phase shows promising results for ruxolitinib-resistant or intolerant patients, an expansion phase will be opened to further characterize the efficacy of idasanutlin.

  34. Baseline and Mean Change From Baseline Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPN-SAF TSS) Over Time

    MPN-SAF Total Symptom Score is the sum of the following 10 items: early satiety, abdominal discomfort, inactivity, concentration issues, night sweats, Itching, Bone pain, Fever and Unintentional weight loss last 6 months and fatigue. The participant provides a severity score for each symptom on a scale of 0 as a minimum score (none/absent) to 10 (worst imaginable) as a maximum score. Baseline (Cycle 1, Day 1) MPN-SAF total symptom score and the mean change from baseline score at each timepoint are reported. The change from baseline score was calculated by subtracting the post-baseline score from the baseline score. The study was pre-maturely terminated by the sponsor's decision due to non-transformative efficacy and poor long-term tolerability of the dosing schedule as well as due to chronic gastrointestinal toxicity, therefore did not reach the end of study.

    Time frame: Baseline (Cycle 1 Day 1), Cycle 2 Day 1, Days 28 of Cycles 3, 5, 8 (Week 32), 11, 14, 17 ) Day 28, Cycle 5 Day 28, End of Cycle 8 (Week 32), and Final Visit

    Reported EORTC QLQ-C30 Scores include: Cognitive function, Diarrhea Emotional functioning, Nausea and vomiting, Social functioning, Physical functioning, Global health status/QoL and Role functioning. The questions use a 4-point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale \[1 'very poor' to 7 'Excellent'\]). Scores are averaged and transformed to 0-100 scale; higher score=better level of functioning or greater degree of symptoms. The study was pre-maturely terminated by the sponsor's decision due to non-transformative efficacy and poor long-term tolerability of the dosing schedule as well as due to chronic gastrointestinal toxicity, therefore did not reach the end of study.

    Time frame: Baseline (Cycle 1 Day 1), Cycle 2 Day 1, Cycles 3, 5, 8, 11, 14, 17, 20 Day 28 and Final Visit

  36. Frequency Count of Participant Responses to the Patient Global Impression of Change (PGIC) Question Over Time

    The PGIC is a one-item measure used to assess perceived treatment benefit. Participants were asked "Since the start of the treatment you've received in this study, your polycythemia vera (PV) symptoms are: 'very much improved', 'much improved', 'minimally improved', 'no change', 'minimally worse', 'much worse', and 'very much worse'. The study was pre-maturely terminated by the sponsor's decision, therefore did not reach the end of study.

    Time frame: Cycle 2 Day 1, Cycle 3 Day 28, Cycle 5 Day 28, End of Cycle 8 (Week 32), and every 3 cycles thereafter (1 cycle is 28 days) until end of study (up to 2 years)

The number of participants with a durable response lasting at least 12 weeks from Week 32 is analyzed by the type of response achieved: Hct control, complete hematologic response, ELN 2009 response criteria, and composite response, if applicable. Reported result data start from Cycle 11 Day 28 which is 12 weeks after Week 32 (Cycle 8 Day 28). There was one timepoint for which the participants qualify. The study was pre-maturely terminated by the sponsor's decision due to non-transformative efficacy and poor long-term tolerability of the dosing schedule as well as due to chronic gastrointestinal toxicity, therefore did not reach the planned end of study.

SecondaryTotal Number of Participants With Adverse Events by Severity, Graded According to NCI CTCAE v4.0

An adverse event is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not considered related to the study drug. The adverse event severity grading scale for the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 (NCI CTCAE v4.0) will be used for assessing adverse event severity. During the final analyses, the focus was on the Adverse Events of severity grades \>/=3 as shown below. The extensive listings of all grade AEs are available at request. The study was pre-maturely terminated by the sponsor's decision due to non-transformative efficacy and poor long-term tolerability of the dosing schedule as well as due to chronic gastrointestinal toxicity, therefore did not reach the planned end of study.

SecondaryChange From Baseline in Pulse Rate

Vital signs were measured prior to the infusion while the participant was in a seated position. The baseline value at visit and the change from baseline value at each timepoint are reported. The change from baseline value was calculated by subtracting the post-baseline value from the baseline value. The study was pre-maturely terminated by the sponsor's decision due to non-transformative efficacy and poor long-term tolerability of the dosing schedule as well as due to chronic gastrointestinal toxicity, therefore did not reach the planned end of study.

The ECOG performance status is a scale used to quantify cancer patients' general well-being and activities of daily life. The scale ranges from 0 to 5, with 0 denoting perfect health and 5 indicating death. The 6 categories are 0=Asymptomatic (Fully active, able to carry on all pre-disease activities without restriction), 1=Symptomatic but completely ambulatory, 2=Symptomatic, \< 50% in bed during the day (Ambulatory and capable of all self-care but unable to carry out any work activities. Up and about more than 50% of waking hours), 3=Symptomatic, \> 50% in bed, but not bedbound (Capable of only limited self-care, confined to bed or chair 50% or more of waking hours), 4=Bedbound (Completely disabled. Cannot carry on any self-care. Totally confined to bed or chair), 5=Death. Only baseline data were collectable. The study was pre-maturely terminated by the sponsor's decision, therefore did not reach the planned end of study.

SecondaryBaseline and Mean Change From Baseline Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPN-SAF TSS) Over Time

MPN-SAF Total Symptom Score is the sum of the following 10 items: early satiety, abdominal discomfort, inactivity, concentration issues, night sweats, Itching, Bone pain, Fever and Unintentional weight loss last 6 months and fatigue. The participant provides a severity score for each symptom on a scale of 0 as a minimum score (none/absent) to 10 (worst imaginable) as a maximum score. Baseline (Cycle 1, Day 1) MPN-SAF total symptom score and the mean change from baseline score at each timepoint are reported. The change from baseline score was calculated by subtracting the post-baseline score from the baseline score. The study was pre-maturely terminated by the sponsor's decision due to non-transformative efficacy and poor long-term tolerability of the dosing schedule as well as due to chronic gastrointestinal toxicity, therefore did not reach the end of study.

The questions use a 4-point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale \[1 'very poor' to 7 'Excellent'\]). Scores are averaged and transformed to 0-100 scale; higher score=better level of functioning or greater degree of symptoms. The study was pre-maturely terminated by the sponsor's decision due to non-transformative efficacy and poor long-term tolerability of the dosing schedule as well as due to chronic gastrointestinal toxicity, therefore did not reach the end of study.

SecondaryFrequency Count of Participant Responses to the Patient Global Impression of Change (PGIC) Question Over Time

The PGIC is a one-item measure used to assess perceived treatment benefit. Participants were asked "Since the start of the treatment you've received in this study, your polycythemia vera (PV) symptoms are: 'very much improved', 'much improved', 'minimally improved', 'no change', 'minimally worse', 'much worse', and 'very much worse'. The study was pre-maturely terminated by the sponsor's decision, therefore did not reach the end of study.

Time frame:
Cycle 2 Day 1, Cycle 3 Day 28, Cycle 5 Day 28, End of Cycle 8 (Week 32), and every 3 cycles thereafter (1 cycle is 28 days) until end of study (up to 2 years)
