A Phase 2 Study of LTI-03 in Patients With Idiopathic Pulmonary Fibrosis
Lead Sponsor:
Rein Therapeutics
Conditions:
Idiopathic Pulmonary Fibrosis (IPF)
Eligibility:
All Genders
40+ years
Phase:
PHASE2
Brief Summary
Rationale: LTI-03 is an experimental medication breathed into the lungs using an inhaler. It is being studied for the treatment of Idiopathic Pulmonary Fibrosis (IPF). IPF is a progressive, fatal lung...
Eligibility Criteria
Inclusion
- Male or female age 40 years or older.
- Willing and able to provide written informed consent.
- Diagnosis of IPF within 5 years of Screening as confirmed by a centrally read HRCT of the chest as defined by the ATS/ERS/JRS/ALAT guideline. HRCT lung fibrosis by central read during screening must involve ≥ 10% of the lung and be greater than emphysema involvement of the lung.
- Forced vital capacity (FVC) percent predicted ≥ 45%.
- Diffusion capacity of the lungs for carbon monoxide (DLCO), hemoglobin-corrected percent predicted ≥ 30% within 8 weeks prior to Randomization.
- Participants receiving nintedanib, pirfenidone, or nerandomilast (where approved for marketing) for IPF treatment must have been on a stable prescribed dose for at least 12 weeks prior to Randomization.
- Participants who previously received nintedanib, pirfenidone, or nerandomilast must have discontinued treatment at least 8 weeks prior to Randomization.
- Able to adequately self-administer study drug using the protocol-specified inhaler device.
Exclusion
- Forced expiratory volume in 1 second (FEV1)/FVC \< 0.7.
- Use of N-acetyl cysteine or other supplements including but not limited to quercetin, omega-3 fatty acids, dehydroepiandrosterone, polyphenols, and phytochemicals within 7 days prior to Randomization and through Week 24.
- Use of systemic corticosteroids at doses \> 10 mg/day of prednisone or equivalent within 28 days prior to Randomization.
- Active smoker.
- Pulmonary exacerbation within 3 months prior to Screening.
- Febrile pulmonary illness requiring antibiotic treatment within 28 days prior to Randomization.
- Participation in a clinical study or treatment with an investigational drug or device within 28 days of the Screening Visit (or 5 half-lives of the investigational agent, whichever is longer).
- History or evidence at Screening of significant renal impairment with estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73m2.
- History or evidence at Screening of significant hepatic impairment with bilirubin \> 3 mg/dL (\> 51.3 μmol/L) and albumin \< 2.8 g/dL (\<28 g/L) and PT prolongation \> 6 sec or INR \> 2.3 while not on anticoagulant medication.
- Active or history of malignancies within 5 years prior to Randomization, with the exception of localized nonmetastatic basal or squamous cell carcinoma of the skin, in situ carcinoma of the cervix, or prostate cancer.
- Serious or active medical or psychiatric condition which, in the opinion of the Investigator, may interfere with treatment, assessment, or compliance with the protocol; or an expected survival of less than 24 weeks.
- Contraception and Pregnancy
- Positive pregnancy test in female participants of childbearing potential (defined below).
- Female participants who are lactating.
- Females of childbearing potential (FOCBP) and men with partners of childbearing potential who do not agree to use an acceptable form of contraception for the duration of study treatment and for at least 90 days after the last dose of study drug. Male participants who do not agree to refrain from donating sperm during this same period.
