The Lille score predicts response of AH subjects to treatment with glucocorticoids, such as prednisolone. This score is based on age, serum albumin, creatinine, PT, and the difference in bilirubin between pre-treatment and Day 7 post-treatment. The Lille score ranges from 0.01 to 1.00. A score \>0.45 predicts a higher risk of death and the recommendation to stop steroid administration. Lille Score = Exp(-R)/(1 + Exp(-R)) Where: R = \[3.19 - (0.101 x Age in years)\] + (1.47 x Albumin in g/dL) + \[0.28215 x (Bilirubin initial - Bilirubin day 7 in mg/dL)\] - (0.206 x Creatinine in mg/dL) - (0.11115 x Bilirubin initial in mg/dL) - (0.0096 x PT in seconds) NOTE: When calculating Lille, use "baseline" values for ALL parameters EXCEPT bilirubin at Day 7. Baseline would be the Day 1 Pre-dose sample result, if available. If not available, then use the Screening sample result.
The MELD score at enrollment is a good predictor for AH patient prognosis. Laboratory values for international normalized ratio (INR), serum creatinine (sCr) and bilirubin are used to calculate the MELD score. The MELD score ranges from 6.0 to 40.0 (capped) with a higher score predicting a higher risk of death. A sequentially improving MELD score is associated with a better chance of recovery. MELD score will be calculated using the original formula (pre-2016) which does not include serum sodium level. Original MELD Score = (0.957 x Ln(Serum Creatinine in mg/dL) + 0. 378 x Ln(Serum Bilirubin in mg/dL) + 1.120 x Ln (INR) + 0.643) x 10 Note: (1) If patient received two or more dialysis treatments within the prior 7 days, then the value for serum creatinine will be set to 4.0. (2) If any laboratory value is less than 1.0, the value will be set to 1.0 for the MELD score calculation, in order to avoid negative values resulting from taking the natural log of values less than 1.
The MELD Score %change from baseline is a %change between 2 time points, baseline and value at a specific time point (Day 7 or Day 28). MELD score is a good predictor of outcome. A declining MELD score suggests disease improvement. Lab values for international normalized ratio (INR), serum creatinine (sCr) and bilirubin are used to calculate the MELD score. MELD score will be calculated using the original formula (pre-2016) which does not include serum sodium level. Original MELD Score = (0.957 x Ln(Serum Creatinine in mg/dL) + 0. 378 x Ln(Serum Bilirubin in mg/dL) + 1.120 x Ln (INR) + 0.643) x 10 Note: (1) If patient received two or more dialysis treatments within the prior 7 days, then the value for serum creatinine will be set to 4.0. (2) If any laboratory value is less than 1.0, the value will be set to 1.0 for the MELD score calculation, in order to avoid negative values resulting from taking the natural log of values less than 1.

DUR-928 is an investigational small molecule being studied for the treatment of plaque psoriasis and alcoholic hepatitis. It is in Phase 2 clinical development and is not yet approved by the FDA.
The molecular target of DUR-928 has not been disclosed in available information. It is a small molecule being evaluated for its effects in plaque psoriasis and alcoholic hepatitis, but its specific mechanism of action is not publicly detailed.
DUR-928 is being developed by DURECT Corporation, a biopharmaceutical company listed on NASDAQ under the ticker symbol DRRX.
DUR-928 is in Phase 2 clinical development. It has completed multiple Phase 2 trials, including studies in alcoholic hepatitis and plaque psoriasis, but it remains investigational and is not FDA approved.
DUR-928 has been studied in three Phase 2 trials: NCT03432260 and NCT04563026 for alcoholic hepatitis, and NCT03837743 for plaque psoriasis. All trials are completed, with a total enrollment of 326 participants.
No alternative names for DUR-928 have been disclosed. It is referred to solely as DUR-928 in clinical trial records and by its developer, DURECT Corporation.
