NCT03972943

Brief Summary

This early phase I trial studies how well the use of a continuous positive airway pressure (CPAP) machine works in treating obstructive sleep apnea in patients with polycythemia vera or essential thrombocythemia. Obstructive sleep apnea is a condition where a person stops breathing during sleep, and is estimated to affect 30 to 50 percent of patients with polycythemia vera or essential thrombocythemia. A patient with obstructive sleep apnea typically snores, has disrupted sleep, experiences morning headaches, and has daytime sleepiness. Patients diagnosed with obstructive sleep apnea are typically treated with a device called CPAP. The CPAP provides pressurized air that keeps upper air passages open during sleep and may prevent them from narrowing or collapsing as occurs during snoring or sleep apnea.

Outcome Measures

Primary Outcomes (2)

  • Change in Myeloproliferative Neoplasm Symptom Assessment Form - Total Symptom Score (MPN-SAF TSS)

    Will be tested at the two-sided 0.025 significance level to provide overall control of the type I error for the co-primary endpoints at 0.05. The endpoints will be summarized by mean, median, range, standard deviation, interquartile range and boxplots. Scatterplots will be used to show bivariate associations. An assessment of normality will be made prior to statistical testing. Paired t tests will be used to analyze endpoints that are sufficiently Gaussian in distribution. Paired Wilcoxon tests will be used to analyze variables that are highly skewed or otherwise non-Gaussian in distribution.

    Baseline, after 3 months, and after 6 months on trial

  • Change in JAK2 V617F allele burden

    Will be tested at the two-sided 0.025 significance level to provide overall control of the type I error for the co-primary endpoints at 0.05. The endpoints will be summarized by mean, median, range, standard deviation, interquartile range and boxplots. Scatterplots will be used to show bivariate associations. An assessment of normality will be made prior to statistical testing. Paired t tests will be used to analyze endpoints that are sufficiently Gaussian in distribution. Paired Wilcoxon tests will be used to analyze variables that are highly skewed or otherwise non-Gaussian in distribution.

    Baseline, after 3 months, and after 6 months on trial

Other Outcomes (3)

  • Proportion of patients with a diagnosis of obstructive sleep apnea (OSA)

    During the OSA screening

  • Leucocytes, platelets, red cell counts, and tumor necrosis factor (TNF) analysis

    Baseline, after 3 months, and after 6 months on trial

  • Thrombotic and inflammatory marker levels for all patients

    Baseline, after 3 months, and after 6 months on trial

Eligibility Criteria

Age30 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • OSA SCREENING ELIGIBILITY CRITERIA: Documented diagnosis of essential thrombocythemia or polycythemia vera by either 2008 WHO criteria or 2016 WHO Criteria prior to screening.
  • OSA SCREENING ELIGIBILITY CRITERIA: For subjects receiving therapy for PV or ET (i.e. hydroxyurea, peginterferon, etc.): Patients must be on a stable dose for \>= 28 days prior to study entry and expected to remain on a stable dose for the duration of trial participation. It is anticipated that during the 6 month duration of study, there will not be any dose modification of hydroxyurea or interferon and this will be communicated to treating providers and patient during enrollment into the trial. However, clinically indicated dose modification of PV/ET therapy while on trial will not necessitate CPAP study discontinuation.
  • OSA SCREENING ELIGIBILITY CRITERIA: Subject must have =\< 20.0 pack-year smoking history OR have quit smoking =\> 3 years ago and do not have any current symptoms of COPD and/or have normal pulmonary function tests.
  • OSA SCREENING ELIGIBILITY CRITERIA: Eastern Cooperative Oncology Group (ECOG) performance status 0-2.

  • OSA SCREENING ELIGIBILITY CRITERIA: Highly effective contraception for both male and female subjects from study enrollment through treatment, and for at least 3 months after last study treatment administration if the risk of conception exists.
  • OSA SCREENING ELIGIBILITY CRITERIA: Able to provide informed consent and willing to sign an approved consent form that conforms to federal and institutional guidelines.
  • OSA SCREENING ELIGIBILITY CRITERIA: Able to read and complete required study questionnaires.
