Study of Trans Sodium Crocetinate in Patients With Interstitial Lung Disease

Study Purpose

This is a randomized, placebo-controlled study of Trans Sodium Crocetinate (TSC) in patients with Interstitial Lung Disease (ILD), age 30-85 (inclusive). The primary objective of the study is to determine the effect of TSC on lung function as measured by diffusing capacity of the lungs for carbon monoxide (DLCO) in patients with ILD; the secondary objectives are to determine the effect of TSC on the 6-minute walk test (6MWT), heart rate recovery (HRR), and Borg Scale in patients with ILD.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 30 Years - 85 Years

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
