Third Harmonic Bio Announces First Quarter 2023 Financial Results

Company Progresses Preclinical Next-Generation oral KIT Inhibitor for Mast Cell-Mediated Inflammatory Diseases

SAN FRANCISCO, May 11, 2023 (GLOBE NEWSWIRE) -- Third Harmonic Bio, Inc. (Nasdaq: THRD), a biopharmaceutical company focused on advancing the next wave of medicine for inflammatory diseases, today announced financial results for the first quarter ended March 31, 2023.

“We are pleased with our progress on our next generation oral KIT inhibitor program, and plan to announce our new development candidate this year,” said Natalie Holles, Chief Executive Officer of Third Harmonic Bio. “In addition, our preclinical mechanistic studies to elucidate the cause of the observed transaminitis with our previous development candidate, THB001, have yielded important insights that we are applying to our next-generation program. We continue to believe that an oral small molecule KIT inhibitor holds the potential for meaningful impact on the treatment landscape for mast-cell mediated inflammatory diseases such as chronic urticaria.”

In addition to the announcement of a development candidate in 2023, the company intends to present the full data set from the discontinued Phase 1b chronic inducible urticaria study for THB001 at an upcoming scientific conference. As stated previously, a preliminary analysis of the five subjects dosed showed evidence of pharmacodynamic and clinical activity with THB001 in that study.

Summary of Financial Results

Cash Position: Cash and cash equivalents totaled $282.2 million as of March 31, 2023. Based on the company's current operating plan, Third Harmonic Bio believes that its existing cash and cash equivalents, will be sufficient to fund its operating expenses and capital expenditure requirements through at least the next twelve months.

R&D Expenses: Research and development (R&D) expenses for the three months ended March 31, 2023 increased to $6.7 million from $6.2 million for the same period in 2022. The increases were primarily due to increases in discovery and development costs relating to the research and nonclinical development of next generation molecules and other discovery programs.

G&A Expenses: General and administrative (G&A) expenses for the three months ended March 31, 2023 increased to $5.3 million from $1.6 million for the same period in 2022. The increases were primarily attributable to increased costs associated with public company costs and personnel-related expenses.

Net Loss: Net loss for the three months ended March 31, 2023 increased to $9.1 million compared to a net loss of $7.8 million for the same period in 2022, primarily due to increases in loss from operations partially offset by increases in interest income.

About Third Harmonic Bio, Inc.
Third Harmonic Bio is a biopharmaceutical company focused on advancing the next wave of medicine for inflammatory diseases through the development of novel highly selective, oral small-molecule inhibitors of KIT, a cell surface receptor that serves as the master regulator of mast cell function and survival. Early clinical studies demonstrate that KIT inhibition has the potential to revolutionize the treatment of a broad range of mast-cell-mediated inflammatory diseases, and that a titratable, oral, intracellular small molecule inhibitor may provide the optimal therapeutic profile against this target.
