Eligibility Criteria:
Inclusion Criteria:
* Diagnosis of IPF as determined by the Principal Investigator based on ATS/ERS/JRS/ALAT guidelines.
* Cough Severity Score ≥ 4 on CS-NRS (Cough Severity Numerical Rating Scale) during the Screening period and Baseline.
* History of chronic cough for at least 8 weeks before screening.
* SpO2 ≥ 92%, taken after at least 5 minutes in a sitting position, undisturbed and non-stimulated (Saturation of Hemoglobin with Oxygen as Measured by Pulse Oximetry).
* FVC ≥ 40% predicted of normal - Forced Vital Capacity, as determined by spirometry adhering to ATS/ERS guidelines.
* DLCO ≥ 25% predicted of normal - Diffusing capacity of the lung for carbon monoxide corrected for hemoglobin, assessed within the last 12 weeks, or at the time of screening.
Exclusion Criteria:
* Currently on continuous oxygen therapy for longer than 16 hours at any level or delivered by any modality. Intermittent oxygen use of any duration over any given 24-hour period is allowed.
* Inadequate swallow reflex as assessed by the ability to sip 3 fluid oz (or 89 mL) of water without coughing or choking.
* Upper or lower respiratory tract infection in the last 8 weeks prior to the baseline visit.
* Clinical history of aspiration pneumonitis.
* Diagnosis of sleep apnea.
* Abnormal kidney or liver functions based on Screening lab results.
* Known hypersensitivity to nalbuphine or to NAL ER excipients
* History of major psychiatric disorder.
* History of substance abuse.
* Significant medical condition or other factors that may interfere with the participant's ability to successfully complete the study.
* Pregnant or lactating female participant.
* Known intolerance (gastrointestinal, central nervous system symptoms), hypersensitivity, drug allergy following the use of an opioid drug.
* Use of opiates is prohibited within 14 days prior to the baseline visit.
* Use of benzodiazepines are prohibited within 14 days prior to the baseline visit and for the duration of the study.
* Monoamine oxidase inhibitors (MAOIs) including methylene blue (methylthioninium chloride) and the antibiotic linezolid are prohibited within 14 days prior to the baseline visit and for the duration of the study.
* Use of oral corticosteroid cough treatment is prohibited within 4 weeks prior to the baseline visit and for the duration of the study.
* Exposure to any investigational medication, including placebo, is prohibited within 4 weeks prior to the baseline visit and for the duration of the study.
* Medications prescribed as cough suppressants are prohibited unless on a stable dose 14-days prior to the baseline visit and are expected to remain on that dose for the duration of the study.
* Use of medications that affect serotonergic neurotransmission and that when used concomitantly with opioids can increase the risk of serotonin syndrome are prohibited unless on a stable dose 14-days prior to the baseline visit and are expected to remain on that dose for the duration of the study.
* Anti-fibrotic medications are prohibited unless on a stable dose for 8 weeks prior to the baseline visit and are expected to remain on that dose for the duration of the study.
* Strong inhibitors/inducers of the P450 Isozymes are prohibited unless on a stable dose for 14-days prior to baseline visit and are expected to remain on that dose for the duration of the study.
* Use of a medication having a "known risk" of Torsade de Pointes (categorized as "KR" on the Credible Meds® website.) 4 weeks prior to Baseline.
* Use of unstable doses of medications associated with a potential risk of QT prolongation but not clearly associated with Torsade de Pointes within 4 weeks of screening.
