Efficacy and Safety of Pirfenidone Treatment in HPS-ILD

Status unconfirmed · Phase 2

Conditions studied: Hermansky Pudlak Syndrome, Interstitial Lung Disease

In brief

This research study will explore the safety and efficacy of the drug, pirfenidone, in patients with a diagnosis of Hermansky-Pudlak Syndrome (HPS) who have an associated interstitial lung disease (ILD) over a planned period of 56 weeks.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Probable or definite diagnosis of HPS based on confirmed genetic mutation or clinical picture characterized by oculo-cutaneous albinism, bleeding disorder, and possible colitis and ILD.
Diagnosis of ILD supported by clinically indicated HRCT prior to Screening, and presence of fibrotic abnormality affecting more than 5% of the lung parenchyma, with or without traction bronchiectasis or honeycombing, on Screening
No features supporting an alternative diagnosis (e.g., infection)
Change in pre-bronchodilator FVC (measured in liters) between Screening (Visit 1) and
Baseline (Visit 2) must be a < 10% relative difference, calculated as:
100%*[absolute value (Screening FVC - Baseline FVC)/Screening FVC
Stable dose (at least three months at the time of Screening) of corticosteroids.
No cytotoxic, immunosuppresive agents, cytokine-modulating, or receptor antagonists agents are allowed (including but not limited to azathioprine, cyclophosphamide, cyclosporine, etanercept, iloprost, infliximab, methotrexate, mycophenolate mofetil, nintedanib, tacrolimus, tetrathiomolybdate, TNF-α inhibitors, rituximab, abatacept, tofacitintib, tociluzimab).
Able to understand and sign a written informed consent form

You may not qualify if…

Not a suitable candidate for enrollment or unlikely to comply with the requirements of this study, in the opinion of the investigator
Cigarette smoking within 3 months of Screening or unwilling to avoid tobacco products throughout the study
History of clinically significant environmental exposure known to cause pulmonary fibrosis (PF), including but not limited to drugs (such as amiodarone), asbestos, beryllium, radiation, and domestic birds
Concurrent presence of other interstitial lung disease, including but not limited to radiation, drug toxicity, sarcoidosis, hypersensitivity pneumonitis, bronchiolitis obliterans organizing pneumonia, human immunodeficiency virus (HIV), viral hepatitis, and cancer
Concurrent presence of other pleuropulmonary manifestations inconsistent with HPS- ILD
Presence of pleural effusion occupying more than 10% of the hemithorax on Screening HRCT
Clinical diagnosis of a connective tissue disease or overlap syndrome (including but not limited to rheumatoid arthritis, scleroderma, polymyositis/dermatomyositis, systemic lupus erythematosus)
Coexistent clinically significant COPD/emphysema or asthma in the opinion of the site principle investigator
Clinical evidence of active infection, including but not limited to bronchitis, pneumonia, sinusitis, urinary tract infection, or cellulitis
Any history of malignancy diagnosed within 5 years of screening, other than basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or low grade cervical carcinoma in situ.
History of severe hepatic impairment or end-stage liver disease
History of end-stage renal disease requiring dialysis
History of unstable or deteriorating cardiac or disease, myocardial infarction within the previous year, heart failure within the last 3 years, or cardiac arrhythmia requiring drug therapy
Any condition that, in the opinion of the investigator, might be significantly exacerbated by the known side effects associated with the administration of pirfenidone
For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use two adequate methods of contraception, including at least one method with a failure rate of <1% per year, during the 52 weeks of treatment.
A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus).
Examples of contraceptive methods with a failure rate of <1% per year include bilateral tubal ligation, male sterilization, established and proper use of hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
For men who are not surgically sterile: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below:
With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for at least 118 days after the last dose of pirfenidone.
Men must refrain from donating sperm during this same period.
Investigational therapy, defined as any drug that has not been approved for marketing for any indication in the country of the participating site including pirfenidone, at the time of Screening
History of alcohol or substance abuse in the past 2 years, at the time of Screening
Family or personal history of long QT syndrome
Any of the following liver function test criteria above specified limits:
