A Phase 2a, Randomized, Double-blind, Placebo-Controlled Study of the Safety and Efficacy of MTX-463 in Participants with Idiopathic Pulmonary Fibrosis (IPF)

Condition

Idiopathic Pulmonary Fibrosis

Eligibility

Eligible Ages: Over 40 Years
Eligible Sex: All
Accepts Healthy Volunteers: No

Inclusion Criteria

Participants with IPF of any gender ≥ 40 years of age at time of signing the informed consent. - Able to understand the study and provide signed, written informed consent. - Able to read and understand the language of the informed consent and other trial-related materials. - Meet the American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Association (ATS/ERS/JRS/ALAT) 2019 criteria for the diagnosis of IPF; Diagnosed with IPF within 7 years of screening. - If a participant is on treatment with pirfenidone or nintedanib, the dose of the medication must be stable for ≥ 90 days prior to Screening with plans to maintain the same dose throughout the study treatment period. Use of both agents together is not permitted. - If a participant was on treatment with nintedanib or pirfenidone, and the agent has been discontinued, this must have occurred ≥ 30 days prior to Screening. At Screening, there must also be no plan to start either of these medications for the duration of the study. - FVC of ≥ 45 percent predicted (pp) at screening. - DLCO of ≥ 25pp at screening. - Willing and able to complete all protocol required study visits and procedures. - All participants of childbearing potential must have a negative serum pregnancy test at Screening. - Participants with reproductive potential must agree to use and follow medically approved contraceptive precautions during the study

Exclusion Criteria

Acute exacerbation of IPF within 6 months of Screening or during the Screening Period. - Forced expiratory volume in 1 second (FEV1)/FVC ratio of <0.7 at Screening. - Requirement for continuous supplemental oxygen. Intermittent supplemental oxygen use (e.g., during exercise or sleep) is permitted. - Expected to receive a lung transplant within the study duration. - Current active bacterial infection or use of antibiotics for suspected lung infection in the 30 days prior to Screening. - Planned surgery within the study duration. - Clinically significant pulmonary hypertension. - Use of immunosuppressive therapy (excluding corticosteroids).
