Asciminib (ASC) in Combination with Imatinib (IMA), Nilotinib (NIL), or Dasatinib (DAS) May be a Potential Treatment (Tx) Option in Patients (Pts) with Philadelphia Chromosome–Positive Chronic Myeloid Leukemia in Chronic Phase or Accelerated Phase (Ph+ CML-CP/AP): Final Results from the Asciminib Phase 1 Study (ASH 2023) - P1 | "INTRODUCTION: ATP-competitive tyrosine kinase inhibitors (TKIs) have extended the life expectancy of pts with CML. ASC in combination with ATP-competitive TKIs, while associated with a higher AE burden vs ASC monotherapy, demonstrated rapid efficacy in the enrolled pt population. The MTD for ASC + IMA was reached at ASC 60 mg QD + IMA 400 mg QD (Table); the MTD for ASC + NIL or DAS was not reached. ASC 40 or 60 mg QD + IMA 400 mg QD, ASC 40 mg BID + NIL 300 mg BID, and ASC 80 mg QD + DAS 100 mg QD were recommended doses for expansion."

Asciminib (ASC) Add-on to Imatinib (IMA) Demonstrates Sustained High Rates of Ongoing Therapy and Deep Molecular Responses (DMRs) with Prolonged Follow-up in the ASC4MORE Study (ASH 2023) - P2 | "Here, we report results of ASC add-on to IMA vs continued IMA vs switch to nilotinib (NIL) and of pts who crossed over from continued IMA to ASC add-on after 96 wks of Tx in pts not achieving DMR with ≥1 y of IMA as their first TKI (cutoff: 6 Mar 2023)...The top reasons for discontinuation were pt decision (9.5% with ASC 40 mg add-on), adverse events (AEs; 14.3% and 33.3%, with ASC 60 mg add-on and NIL, respectively), and physician decision (66.7% with IMA, all of whom crossed over to ASC 60 mg add-on)... Among pts not achieving DMR after ≥1 y on IMA, more pts achieved MR4.5 with ASC add-on to IMA than with continuing IMA or switching to NIL at wk 96. Pts crossing over from IMA to ASC 60 mg add-on were still able to achieve DMRs. ASC add-on to IMA was well-tolerated, with no new or worsening safety findings compared with those known for ASC alone."

Sagimet Biosciences to Host Virtual KOL Event, 'A New Mechanism of Action in Treating Acne: Update on Positive Phase 3 Denifanstat Trial for the Treatment of Moderate to Severe Acne' on June 16, 2025 (GlobeNewswire) - "The event will feature key opinion leader (KOL) Neal Bhatia, MD (Director of Clinical Dermatology at Therapeutics Clinical Research in San Diego), who will join company management to review positive efficacy and tolerability results from a Phase 3 clinical trial evaluating denifanstat for the treatment of moderate to severe acne vulgaris in China conducted by Sagimet’s license partner Ascletis....In the Phase 3 study, denifanstat met all primary and secondary endpoints versus placebo and was generally well tolerated. The robust Phase 3 results underline the potential of FASN inhibition as a novel mechanism of action to address acne, a condition that impacts more than 50 million people in the U.S. annually. Management will also discuss the Company’s recently initiated Phase 1 first in-human study with its second oral FASN inhibitor drug candidate, TVB-3567, which is planned to be developed for acne in the U.S."

Efficacy and Safety Results from ASC4MORE, a Randomized Study of Asciminib (ASC) Add-on to Imatinib (IMA), Continued IMA, or Switch to Nilotinib (NIL) in Patients (Pts) with Chronic-Phase Chronic Myeloid Leukemia (CML-CP) Not Achieving Deep Molecular Responses (DMRs) with ≥1 Year of IMA (ASH 2022) - P2, P3 | "In the phase 3 ASCEMBL study, ASC led to superior major molecular response vs bosutinib (BOS) at wk 24 and 96...Top reasons for discontinuation were pt decision in the ASC 40-mg add-on arm (9.5%), AEs in the ASC 60-mg add-on and NIL arms (14.3% and 23.8%, respectively), and physician decision in the IMA arm (57.1%) (pts who crossed over to the ASC 60-mg add-on arm were considered discontinued for IMA arm)... More pts achieved DMR at wk 48 with ASC add-on to IMA vs continued IMA or switch to NIL in pts not achieving DMR with IMA alone for ≥1 y. In this population of pts tolerating IMA for ≥1 y, ASC add-on was generally well tolerated. While not powered to identify the best arm for achievement of DMR in this setting, the high rate of DMR in the ASC add-on arms is promising. Further studies are needed to assess if ASC alone can provide equivalent efficacy and better tolerability vs add-on to IMA."

Efficacy of ASC60, an oral fatty acid synthase inhibitor, in two tumor mouse models (AACR 2022) - "Previous in vitro testing showed that inhibition of palmitate synthesis by ASC60 was 137-fold lower in mouse than in human (IC50: 2.05 µM in mouse vs 0.015 µM in human). However, results of the present studies showed that ASC60 could suppress tumor growth and/or expand lifespan in the two tumor mouse models either alone or in combination with mPD-1 antibody. ASC60 will possibly demonstrate better efficacies in human."
