NOVEL, FIRST-IN-CLASS, FATTY ACID SYNTHASE (FASN) INHIBITOR TVB-2640 DEMONSTRATES ROBUST CLINICAL EFFICACY AND SAFETY IN A GLOBAL PHASE 2 RANDOMIZED PLACEBO-CONTROLLED NASH TRIAL (FASCINATE-1) CONDUCTED IN THE US AND CHINA

• Presentation Type: Oral, Parallel Session
• Publication Number: 141
• Session Title: Parallel 21: NAFLD and NASH: Clinical Trials of Novel Therapeutics
• Presenting Author: Dr. Rohit Loomba, MD, University of California
• Session Broadcast Date and Time: Sunday, November 14, 2021, 6:30 – 8:00 PM EST
• Highlights:
  - TVB-2640 is an oral, once-daily, first-in-class small molecule FASN inhibitor that reduces excess liver fat, inhibits inflammatory and fibrogenic pathways.
  - Subjects with MRI-PDFF ≥8% and fibrosis (MRE ≥2.5 kPa or biopsy F1-F3) were randomized 2:1 to TVB-2640 or placebo once daily (US N=99; China N=30) for 12 weeks to access the efficacy and safety of TVB-2640.
  - TVB-2640 was well-tolerated, with no AEs ≥ Gr. 3 and no on treatment SAEs.
  - PK profiles (50mg) were similar in the U.S. and China.
  - TVB-2640 reduced liver fat and decreased alanine aminotransferase（ALT）in both populations, that combined had a relative PDFF reduction of 28.2% (50mg, N=48) at W12 v. 6.4% placebo (N=19, p=0.019) and absolute PDFF reduction of 5% v. 1.6% placebo (p<0.0001). The PDFF response rates were 56% (50mg) v. 15% placebo.

A PHASE Ib STUDY TO EVALUATE THE SAFETY, TOLERABILITY, PHARMACOKINETICS AND PHARMACODYNAMICS OF ASC41, A THR-β AGONIST, FOR 28-DAYS IN OVERWEIGHT AND OBESE SUBJECTS WITH ELEVATED LDL-C, A POPULATION CHARACTERISTIC OF NAFLD

• Presentation Type: Poster Presentation
• Publication Number: 1851
• Session Title: NAFLD and NASH: Experimental: Clinical
• Presentation time: Friday, November 12, 2021, 6:00-11:55 AM EST
• Highlights:
  - ASC41 is a small molecule, hepatic targeting, potent and selective thyroid hormone receptor beta (THRβ) agonist prodrug, which is converted to its pharmacologically active metabolite ASC41-A by CYP3A4 in the liver.
  - Twenty overweight and obese subjects with elevated low density lipoprotein cholesterol (LDL-C) (>110 mg/dL) were treated with ASC41 10mg oral tablets or matching placebo tablets with the ratio of 3:1 once daily in this randomized, double-blind, placebo controlled clinical study to evaluate the safety, tolerability, pharmacokinetics and lipid lowering potential of ASC41 oral tablets.
  - Compared with placebo, lipid parameters (LDL-C, TG, TC, Apo-B, and LP (a)) for those treated with ASC41 showed clinically meaningful and statistically significant reductions (P<0.05).
  - ASC41 was tolerable and had a benign adverse event (AE) profile with no serious adverse reactions and no adverse reactions above Grade 3.

ASC42, A NOVEL NON-STEROIDAL FXR AGONIST, DEMONSTRATES A NORMAL CHOLESTEROL PROFILE AND LACK OF PRURITUS AT THERAPEUTIC DOSES IN A 14-DAY PHASE I RANDOMIZED, DOUBLE-BLIND, PLACEBO CONTROLLED STUDY IN HEALTHY VOLUNTEERS

• Presentation Type: Poster Presentation
• Publication Number: 1854
• Session Title: NAFLD and NASH: Experimental: Clinical
• Presentation time: Friday, November 12, 2021, 6:00-11:55 AM EST
• Highlights:
  - ASC42 is a potent, orally available, non-steroidal farnesoid X receptor (FXR) agonist under clinical development for NASH.
  - Sixty-four healthy volunteers (8 cohorts n=8 (6 active:2 placebo) were dosed with 5-200mg (single-ascending doses) and 14 days of 5-50mg qd (multi-ascending doses), to evaluate the safety and tolerability of ASC42 and to establish the PK and PD profiles of ASC42.
  - No pruritus was observed during the 14-day treatment at the human therapeutic dose of 15mg.
  - ASC42 for 14-days was well tolerated and safe, without elevated ALT/ aspartate aminotransferase (AST) or lipid parameter abnormalities at doses within the therapeutic dose range.
  - FXR targets activated biomarker of fibroblast growth factor 19 (FGF19) levels increased 1,632% from baseline at Day-14 with the dose of 15mg.
  - FXR targets activated biomarker of 7α-hydroxy-4-cholesten-3-one (C4) levels decreased 93% from baseline at Day-14 with the Dose of 15mg.
  - Based on the study data, 15 mg qd has been selected as one of 3 doses to be studied in the Phase II trial in patients with NASH.

ASC43F TABLET AS A ONE-PILL, ONCE-A-DAY FIXED-DOSE COMBINATION (FDC) OF ASC41, A THR-β AGONIST, AND ASC42, AN FXR AGONIST, DEMONSTRATED COMPARABLE DISSOLUTION PROFILES AND IN VIVO PHARMACOKINETICS VS. SINGLE ASC41 AND ASC42 TABLET

• Presentation Type: Poster Presentation
• Publication Number: 1762
• Session Title: NAFLD and NASH: Experimental: Basic
• Presentation time: Friday, November 12, 2021, 6:00-11:55 AM EST

  - ASC43F is a One-Pill, Once-a-Day FDC of ASC41, an oral hepatic targeting THR-β agonist prodrug, and ASC42, a non-steroidal, selective, potent, oral FXR agonist.
  - Three male beagle dogs were dosed with ASC42 tablet (15mg), ASC41 tablet (5mg) and ASC43F tablet (ASC42/ASC41 15mg/5mg) in a cross-over study design with a 5-day washout period to evaluate in vivo PK. Dissolution profiles of ASC43F tablets were compared with those of single ASC41 and ASC42 tablets.
  - In beagle dogs, the PK parameters of ASC42 and ASC41A in/from ASC43F tablets remained approximately unchanged as compared to those of single ASC41 and ASC42 tablets.
  - The dissolution profiles of ASC41/ASC42 in ASC43F tablets were similar to those of single ASC41 and ASC42 tablets using 4 different pH dissolution media.
  - The stability data demonstrated that ASC43F tablets were stable in the accelerated condition of 40℃/75%RH for 4.5 months (equivalent to 1.5 years in the normal condition).
