The values shown in the cross - study comparisons are directional and may not be directly comparable. 1 Richeldi et al. NEJM, 2014 51 Most Common Adverse Events Reported in INPULSIS vs REVERT IPF Trials Pooled TTI - 101 INPULSIS - 1 and 2 1 TTI - 101 + Nintedanib (n=34) TTI - 101 alone (n=25) Nintedanib (N=638) Placebo (N=423) 33 (97.1) 23 (92.0) 609 (95.5) 379 (89.6) Any adverse event 25 (73.5) 11 (44.0) 398 (62.4) 78 (18.4) Diarrhea 10 (29.4) 4 (16.0) 156 (24.5) 28 (6.6) Nausea 0 (0.0) 1 (4.0) 87 (13.6) 68 (16.1) Nasopharyngitis 4 (11.8) 3 (12.0) 85 (13.3) 57 (13.5) Cough 2 (5.9) 2 (8.0) 64 (10.0) 61 (14.4) Progression of IPF 0 (0.0) 2 (8.0) 67 (10.5) 45 (10.6) Bronchitis 4 (11.8) 0 (0.0) 58 (9.1) 42 (9.9) Upper respiratory tract infection 4 (11.8) 1 (4.0) 49 (7.7) 48 (11.4) Dyspnea • TTI - 101 treated patients reported adverse events consistent with overall expectations for an IPF population • However, addition of nintedanib meaningfully increased incidence of diarrhea

Post hoc Analysis Population Assessment of Individual Patient Trajectory on Study 2 EES 1 on Treatment at 12 - weeks 52 Preliminary Conclusions and Additional Analyses 1 The Efficacy Evaluable Set (EES) consists of all patients defined as all randomized patients who received at least one dose o f I P and have at least one post - baseline acceptable or borderline acceptable forced vital capacity (FVC) result while on - treatment. On treatment is defined as spirometry values obtained when actively receiving IP at pr otocol - defined collection time points and spirometry values when on IP hold at protocol - defined collection time points; excludes spirometry values collected > 14 days of last IP dosing after they have been permane ntl y discontinued from IP. 2 Post hoc analysis population: The additional analysis was limited to patients who were exposed to study drug for 12 weeks. One patient was not exposed to TTI - 101 at 12 weeks; one patient was rem oved from the analysis due to receiving less than 60% of the expected dosing; two patients were removed due to no measurable TTI - 101 observed in the blood as well as no reported adverse events; and one addition al patient was removed as an outlier for the 12 - week analysis as their pulmonary function initially improved on treatment, but was subsequently severely impacted by acute bronchitis deemed unrelated to stud y d rug Placebo n=24 TTI - 101 400mg/day n=8 TTI - 101 800mg/day n=13 Placebo n=24 Pooled TTI - 101 400mg or 800mg n=16 Criteria: duration of treatment, PK data and adverse events 5 patients excluded as the following criteria were not met: • Duration of treatment • TTI - 101 exposure + no adverse events observed • One patient with initial improvement in FVC, subsequently impacted by acute bronchitis (non - related)

Analysis performed on post hoc analysis population comparing baseline to 12 weeks. One patient missing fibrosis score; overal l p ercent change from baseline was calculated using baseline - weighted aggregation to account for differences in initial fibrosis severity with bootstrap - based standard error (SE) 53 TTI - 101 - treated Patients Demonstrated Greater Decline in Fibrosis Score (Baseline to 12 Weeks) vs Placebo 24 24 20* 15* Greater decrease in fibrosis score (improvement in fibrosis) among patients treated with TTI - 101 (either arm) vs placebo - 2.4% - 9.4% -20% -15% -10% -5% 0% 5% Pooled TTI - 101 vs Placebo Baseline - Weighted Percent Change in Fibrosis Score Baseline - Weighted Overall % Change in Fibrosis (SE) Placebo n=24 Pooled TTI - 101 n=15 7% difference in weighted fibrosis score

Analysis performed on post hoc analysis population comparing baseline to 12 weeks. Two patients missing IL - 6 change scores (one placebo, one TTI - 101); Decline assessed using OLS: ordinary least squares regression model and standard errors 54 TTI - 101 - treated Patients Demonstrated Greater IL - 6 Decline vs Placebo -1.5 -1.25 -1 -0.75 -0.5 -0.25 0 TTI - 101 vs Placebo Decline in IL - 6 IL - 6 Slope Placebo n=23 Pooled TTI - 101 n=15 4.5 - fold difference in slope IL - 6 is a key pro - inflammatory cytokine that signals through STAT3; inhibition of STAT3 is expected to reduce downstream inflammatory signaling associated with disease
