ClinConnect Summary

This clinical trial is studying a new medication called GRI-0621 to see if it can help patients with Idiopathic Pulmonary Fibrosis (IPF), a condition that causes scarring in the lungs and makes it hard to breathe. The trial will involve about 36 participants who will either receive GRI-0621 or a placebo (a non-active treatment) for 12 weeks. The goal is to compare the effects of the medication to the placebo to determine its safety and effectiveness. Additionally, a smaller part of the study will look into certain immune cells called NKT cells in a select group of patients.

To be eligible for this trial, participants must be between 40 and 85 years old and have a confirmed diagnosis of IPF. They should also have certain lung function measurements that meet specific criteria. Participants can expect to visit the study site regularly for assessments and may need to undergo a procedure called bronchoscopy to collect samples from their lungs. It's important to know that individuals with serious health issues or specific recent conditions may not be able to participate. Overall, this study aims to explore a potential new treatment option for IPF and improve the lives of those affected by this challenging disease.

  • 15. Use of moderate or strong inhibitors of CYP2C8 (e.g. gemfibrazol, trimethoprim, clopidogrel) or inducers of CYP2C8 (e.g. rifampin) from 7 days or 5 half-lives, whichever is longer, before the first administration of GRI-0621 until cessation of GRI-0621 administration.
  • 16. Subjects who report any active suicidal ideation (SI) or behavior (SB) (i.e. Columbia Suicide Severity Rating Scale (C-SSRS) scores 4 or greater for SI and any positive scores for SB) during Screening or any past history thereof.
  • 17. Current smoker (i.e., use of tobacco products within the last 3 months) of Screening.
  • 18. Current or recent history of drug or alcohol abuse within 12 months of Screening.
  • 19. Participation in any other investigational drug study within 4 weeks of Screening or within 5 times the elimination half-life of an investigational drug.
  • 20. 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).
  • 21. Males, if sexually active, unwilling to practice two highly effective forms of contraception during the study (e.g., condom, or surgical sterilization).
