Brief Summary

SM04646-IPF-03 is a Phase 2a, multi-center, open-label study evaluating the safety and efficacy of a single inhaled, nebulized dose of SM04646 solution over a 12-week treatment regimen in subjects with mild to moderate IPF. A total of approximately 24 subjects will be enrolled in the study (approximately 12 subjects into the "non-bronchoalveolar lavage [BAL]" arm and approximately 12 subjects into the "BAL" arm). Subjects that currently do not require, have failed to tolerate, or have opted not to have treatment with pirfenidone or nintedanib will have the option of participation in the "BAL" arm or participation in the "non-BAL" arm. Subjects currently receiving treatment with pirfenidone or nintedanib must be on stable treatment for a minimum of 12 weeks prior to the Screening Visit. Subjects currently on treatment with pirfenidone or nintedanib may participate in the "non-BAL" arm only.

Eligible subjects will participate in a treatment period of 12 weeks and a follow-up period of 12 weeks. The treatment dosing pattern will follow a 2 weeks on, 2 weeks off regimen, wherein subjects will dose 5 consecutive days of each 7 day "on" week.
