• THB335 Phase 1 SAD/MAD clinical trial progressing; study now on track to report clinical results in 1Q’25
• Strong financial position with cash and cash equivalents totaling $255.3 million as of June 30, 2024

SAN FRANCISCO, Aug. 08, 2024 (GLOBE NEWSWIRE) -- Third Harmonic Bio, Inc. (Nasdaq: THRD), a clinical-stage biopharmaceutical company focused on advancing the next wave of medicine for dermal, respiratory and gastrointestinal inflammatory diseases, today announced financial results for the second quarter June 30, 2024, along with business updates.

“We are making excellent progress in our Phase 1 SAD/MAD clinical trial of THB335 and now expect to report clinical results during the first quarter of 2025,” said Natalie Holles, Chief Executive Officer at Third Harmonic Bio. “In parallel with conduct of this ongoing clinical trial, we are already preparing to move THB335 rapidly into a Phase 2 clinical trial in chronic spontaneous urticaria with subsequent expansion into additional mast cell-mediated diseases.”

The Phase 1 SAD/MAD clinical trial of THB335 is being conducted in healthy volunteers to assess safety and tolerability, characterize pharmacokinetics, and to measure the pharmacodynamic effect by reductions in serum tryptase, a biomarker associated with mast cell activation and correlated with clinical response in urticaria studies. Results are expected in the first quarter of 2025.

Summary of Financial Results

Cash Position: Cash and cash equivalents totaled $255.3 million as of June 30, 2024. 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 2026.

R&D Expenses: Research and development (R&D) expenses increased to $8.4 million for the three months ended June 30, 2024, from $5.3 million for the same period in 2023. R&D expenses for the six months ended June 30, 2024, increased to $14.6 million, from $12.1 million for the same period in 2023. The increases were primarily due to increased spend related to the THB335 clinical program and next-generation discovery efforts, partially offset by decreases in development costs relating to the termination of the THB001 program.

G&A Expenses: General and administrative (G&A) expenses increased to $5.7 million for the three months ended June 30, 2024, from $5.4 million for the same period in 2023. G&A expenses for the six months ended June 30, 2024, increased to $10.7 million, from $10.6 million for the same period in 2023. The increases were primarily attributable to increased personnel-related expenses due to executive recruiting during 2024.

Net Loss: Net loss for the three months ended June 30, 2024, increased to $10.7 million from a net loss of $7.6 million for the same period in 2023. Net loss for the six months ended June 30, 2024, increased to $18.6 million from a net loss of $16.6 million for the same period in 2023, primarily due to increases in research and development expenses that were partially offset by increases in interest income.

About Third Harmonic Bio, Inc.

Third Harmonic Bio is a clinical-stage biopharmaceutical company focused on advancing the next wave of medicine for dermal, respiratory, and gastrointestinal inflammatory diseases through the development of novel, highly selective, 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, small molecule inhibitor may provide the optimal therapeutic profile against this target. Third Harmonic Bio’s lead product candidate, THB335, is a titratable, oral, small molecule inhibitor that is currently in a Phase 1 clinical trial.
