Brief summary: This is a first-in-human, two-part, Phase 1 study that will characterize the safety, tolerability, PK, and immunogenicity of HuL001.

Detailed description: This is a first-in-human, two-part, Phase 1 study that will characterize the safety, tolerability, PK, and immunogenicity of HuL001 after single ascending doses in healthy subjects followed by multiple doses in IPF subjects. The study will be conducted in 2 parts:

* Part A will enroll 3 single ascending doses (SAD) cohorts in healthy subjects. (HuL001:Placebo=4:2)
* Part B will enroll 1 multiple-dose cohort in IPF subjects. The proposed dose of HuL001 will be selected from the single-dose range of HuL001 evaluated in the healthy subjects of Part A. (HuL001=6)
