(Nasdaq: SGMT), a clinical-stage biopharmaceutical company developing novel therapeutics targeting dysfunctional metabolic pathways, today reported financial results for the second quarter ended June 30, 2023, and provided recent corporate updates. “Sagimet has entered a new era as a public company, and I am proud of our team for the successful completion of our IPO and the continued advancement of denifanstat through clinical development in NASH,” said David Happel, Chief Executive Officer of Sagimet. “At EASL, we presented statistically significant results from the planned interim readout of the Phase 2b FASCINATE-2 trial of denifanstat in NASH, and we look forward to announcing the week 52 biopsy results in the first quarter of next year.” Recent Corporate Highlights On July 18, 2023, Sagimet closed an upsized IPO of Series A common stock, at a public offering price of $16.00 per share. Including shares issued pursuant to the exercise of the underwriters’ option, the Company issued 6,026,772 shares of Series A common stock, and received gross proceeds of approximately $96.4 million before deducting underwriting discounts and commissions and other offering expenses payable by Sagimet.In June, Sagimet presented planned interim data at the EASL Congress showing that denifanstat was well-tolerated and met the liver fat response endpoint in the Phase 2b FASCINATE-2 trial in biopsy confirmed F2-F3 NASH patients. 67% of treated patients achieved ≥30% reductions in liver fat at week 26 compared to 18% for placebo (p<0.001) as assessed by MRI-PDFF.In May 2023, Sagimet’s license partner for China, Ascletis Bioscience, announced Phase 2 topline results for denifanstat in acne vulgaris, reporting a statistically significant 61.3% reduction in total lesion count in patients treated with once daily, 50mg of denifanstat for 12 weeks, compared to a 34.2% reduction with placebo. Ascletis reported a statistically significant 65.0% reduction in inflammatory lesion count at 50mg denifanstat compared to a 31.4% reduction with placebo.In April, Sagimet appointed Tony Rimac as Chief Operating Officer and Liz Rozek as General Counsel & Chief Compliance Officer. In August, following the departure of Dennis Hom, Mr. Rimac was appointed as Chief Financial Officer. Anticipated Upcoming Milestones The FASCINATE-2 Phase 2b clinical trial for denifanstat in liver biopsy-confirmed F2-F3 NASH patients is fully enrolled with biopsy results expected in the first quarter of 2024.Sagimet expects to report Phase 1 clinical trial results that characterize the pharmacokinetic profile of denifanstat in patients with impaired hepatic function in the first quarter of 2024. Financial Results for the Three Months Ended June 30, 2023 Cash and cash equivalents for the second quarter ended June 30, 2023 were $18.5 million as of June 30, 2023. The subsequent IPO raised $86.2 million in net proceeds. Based on its operating plan, management expects the combined cash balance to fund operations into the first quarter of 2025. Research and development (R&D) expense for the second quarter ended June 30, 2023 was $4.7 million compared to $6.4 million for the second quarter of 2022. For the six months ended June 30, 2023, R&D expense was $9.2 million compared to $12.2 million for the same period in the prior year. The decrease for both periods was primarily due to a decrease in clinical trial costs for the FASCINATE-2 Phase 2b trial as patients progressed through the trial. General and administrative (G&A) expense for the second quarter ended June 30, 2023 was $2.4 million compared to $0.9 million for the same period in 2022. G&A expense for the six months ended June 30, 2023 was $4.7 million compared to $3.7 million for the same period in the prior year. The increase for both periods was primarily due to an increase in stock-based compensation expense and professional services related to Sagimet’s initial public offering.Net loss for the second quarter ended June 30, 2023 was $6.8 million compared to a net loss of $7.1 million for the second quarter of 2022. The net loss for the six months ended June 30, 2023 totaled $13.4 million compared to $15.8 million for the same period in 2022.
