简要总结
This is a Phase 2a, randomized, double-blind, multi-center, placebo-controlled, parallel-design, 2-arm study. Approximately 36 subjects with IPF will be randomized in a 2:1 ratio for GRI-0621 4.5mg or Placebo. GRI-0621 dose of 4.5mg will be compared with placebo following once daily oral administration for 12 weeks.
Concurrently, a Sub-Study will be conducted, examining the number and activity of NKT cells in BAL, for up to 12 eligible subjects (across various centers).
An early-stage patient variability assessment will be completed when 12 subjects have completed 2 weeks of treatment. Followed by an interim analysis performed when 24 subjects complete 6 weeks of treatment.

- •Any condition with unacceptable risk for bronchoscopy (for Sub-Study subjects only).
- •Current or recent history of clinically significant medical condition, laboratory abnormality, or illness that could place the subject at risk or compromise the quality of the study data as determined by the Investigator.

- •Current or recent history of drug or alcohol abuse within 12 months of Screening.
- •Participation in any other investigational drug study within 4 weeks of Screening or within 5 times the elimination half-life of an investigational drug.
- •Females who are pregnant or breastfeeding, or if of child-bearing potential unwilling to practice two highly effective forms of contraception for at least 1 month prior to initiation of the study drug, during the study, and for 1 month after discontinuing the study drug (e.g., abstinence, intrauterine device or system, combination of barrier and spermicide, hormonal contraceptive, surgical sterilization, or male partner sterilization).
- •Males, if sexually active, unwilling to practice two highly effective forms of contraception during the study (e.g., condom, or surgical sterilization).
- •History of hypersensitivity or intolerance to oral tazarotene.
