About this study

Official title: A Randomized Controlled Study Evaluating the Efficacy and Safety of Pegylated Interferon α-2b in Combination With Ruxolitinib vs. Pegylated Interferon α-2b Monotherapy for Treating Hydroxyurea-resistant/Intolerant Polycythemia Vera

Study purpose: To compare the efficacy and safety of pegylated interferon α-2b in combination with ruxolitinib versus pegylated interferon α-2b alone for treating hydroxyurea-resistant or hydroxyurea-intolerant polycythemia vera.

Read the detailed description

Study purpose: To compare the efficacy and safety of pegylated interferon α-2b in combination with ruxolitinib versus pegylated interferon α-2b alone for treating hydroxyurea-resistant or hydroxyurea-intolerant polycythemia vera.

The subjects will be randomly divided into two groups:

pegylated interferon alpha-2b combined with ruxolitinib group: pegylated interferon alpha-2b at a starting dose of 180ug will be administered subcutaneously once a week; ruxolitinib at a starting dose of 10mg will be administered orally twice daily.

pegylated interferon alpha-2b group: pegylated interferon alpha-2b at a starting dose of 180ug will be administered subcutaneously once a week.

If complete hematologic remission is not achieved after 12 weeks of treatment with pegylated interferon alpha-2b alone, the subject may be switched to the pegylated interferon alpha-2b combined with ruxolitinib group. If ruxolitinib is not tolerated, the subject may be switched to the pegylated interferon alpha-2b group alone.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The cumulative complete hematologic response (CHR) rate

    The proportion of patients who can achieve CHR ( defined as hematocrit lower than 45% without phlebotomies; platelet count < 400×109/L, WBC count < 10×109/L for at least 12 weeks) among all patients.

    Measured: From the start of study treatment (Week 0) up to the end of Week 24.

Secondary outcomes (15)

  2. Cumulative CHR rates at Week 52.

    Cumulative CHR rates at Week 52 will be compared between the two groups.

    Measured: From the start of study treatment (Week 0) up to the end of Week 52.

  3. Time to CHR

    The time of reaching CHR will be compared between the two groups.

  4. The CHR rates after crossover

    The CHR rates within 52 weeks after crossover

    Measured: From the start of study treatment (Week 0) up to the end of Week 52.

  5. The rate of reduction in JAK2V617F, CALR, or MPL gene mutation burden.

    The rate of reduction in JAK2V617F, CALR, or MPL gene mutation burden will be compared between the two groups.

    Measured: From the start of study treatment (Week 0) up to the end of Week 52.

  6. Impact of therapy on non-driver mutations

    To compare the proportion of subjects that display change on key non-driver biomarkers of the disease-DNMT3A, ASXL1, TET2 or other mutations.

    Measured: From the start of study treatment (Week 0) up to the end of Week 52.

  7. Change of splenomegaly

    All subjects with palpable splenomegaly at baseline will undergo ultrasound examination.

    For subjects with palpable splenomegaly at baseline:

    Improvement - no palpable splenomegaly during clinical treatment visits; No progress - ultrasound examination during clinical treatment visits shows an increase in spleen size of ≤ 25%; Progress - Ultrasound examination during clinical treatment visits shows an increase in spleen size of>25%.

    Measured: From the start of study treatment (Week 0) up to the end of Week 52.]

  8. Change of bone marrow pathology

    Bone marrow histological remission defined as the presence of age-adjusted normocellularity and disappearance of trilinear hyperplasia, and absence of grade 1 reticulin fibrosis; no remission defined as the persistence of trilinear hyperplasia; progression defined as disease transformation into post-PV myelofibrosis, myelodysplastic syndrome or acute leukemia.

    The QLQ-C30 V3.0 questionnaire consists of 30 questions, with questions 1-28 scoring 1-4 and questions 29 and 30 scoring 1-7. Therefore, this questionnaire has a minimum score of 30 and a maximum score of 126, and the score is directly proportional to the quality of life.

    Measured: From the start of study treatment (Week 0) up to the end of Week 52.

  14. Change of microcirculation disturbance

    The rate of patients with improvement in microcirculation disturbance (such as pruritus, headache, dizziness, chest tightness, erythematous limb pain and limb paresthesia) will be compared between the two groups

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ruxolitinib and Pegylated interferon α-2b in people with Polycythemia Vera, run by Institute of Hematology & Blood Diseases Hospital, China at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 3 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Lei Zhang, MD (8602223909240, zhanglei1@ihcams.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The cumulative complete hematologic response (CHR) rate (time frame: From the start of study treatment (Week 0) up to the end of Week 24.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jul 2024.
