Tectonic Therapeutic reported a net loss of $12.4 million for Q4 2024, an increase from $7.9 million in Q4 2023. The company's cash and cash equivalents stood at $141.2 million as of December 31, 2024, with a private placement in February 2025 expected to extend the cash runway into Q4 2028. Key business highlights included positive interim results from the TX45 Phase 1b trial and the first subject enrolled in the TX45 Phase 1b Part B trial.
TX45 Phase 1b trial interim analysis showed meaningful improvements in left ventricular function and pulmonary hemodynamics in patients with Group 2 Pulmonary Hypertension in Heart Failure with Preserved Ejection Fraction (PH-HFpEF).
Positive TX45 Phase 1b interim results support endpoints and patient population in the ongoing APEX Phase 2 trial, with topline results expected in 2026.
The TX45 Phase 1b Part B trial enrolled its first subject with Heart Failure with reduced Ejection Fraction (HFrEF) in March 2025.
Cash and cash equivalents of $141.2 million as of December 31, 2024, combined with approximately $185.0 million from a February 2025 private placement, are expected to provide a cash runway into Q4 2028.
Tectonic Therapeutic anticipates its current cash and cash equivalents, combined with proceeds from the recent private placement, will provide a cash runway into Q4 2028, supporting key clinical trial readouts and progression of its HHT program.
