Due to, among other things, positive results from the 200-302 trial, the trial has been terminated early. Resources shifted to new 200-208 GBM trial using information gained from 200-302.

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.
