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.

Description

PRIMARY OBJECTIVES:

I. To understand effects of continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA) on the course of polycythemia vera/essential thrombocythemia (PV/ET).

EXPLORATORY OBJECTIVES:

I. To estimate prevalence of OSA in patients with myeloproliferative neoplasms. II. To understand effects of CPAP for sleep apnea on the course of myeloproliferative neoplasms (MPNs).

III. To correlate OSA severity with thrombotic and inflammatory marker values in patients with PV/ET at baseline.

OUTLINE: Patients are assigned to 1 of 2 cohorts.

COHORT I (OBSERVATIONAL COHORT): Patients not diagnosed with OSA undergo observation for 6 months.

COHORT II (TREATMENT COHORT): Patients diagnosed with OSA and prescribed a CPAP machine for treatment receive continuous treatment with CPAP for 6 months.

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: Negative serum or urine pregnancy test at screening for women of childbearing potential
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
TREATMENT ELIGIBILITY CRITERIA: Eligible for OSA Screening Component portion of this trial
TREATMENT ELIGIBILITY CRITERIA: Diagnosed OSA with Sleep Study score >= 5
TREATMENT ELIGIBILITY CRITERIA: Snoring, Tiredness, Observed Apnea, Blood Pressure, Body Mass Index, Age, Neck Circumference and Gender (STOP-BANG) screening questionnaire score >= 3
TREATMENT ELIGIBILITY CRITERIA: Willingness to comply with required CPAP compliance rate of >= 4hrs/day for 70% of days over 6 months of CPAP treatment
TREATMENT ELIGIBILITY CRITERIA: Able to provide informed consent and willing to sign an approved consent form that conforms to federal and institutional guidelines

Exclusion Criteria
