Shattuck Labs (STTK) reported lower operating losses and trimmed R&D activity as it pivots to its DR3 antagonist program SL-325. Cash and cash equivalents were $50.5 million and total assets were $64.4 million at June 30, 2025, while accumulated deficit stood at $407.9 million. For the six months ended June 30, 2025 the company recognized a net loss of $26.2 million, an improvement from $40.1 million a year earlier, driven by a reduction in research and development expense after winding down SL-172154 activities and completing collaboration services in 2024.
Management states current cash is sufficient to fund operations for at least twelve months. The company expects to initiate enrollment in a Phase 1 trial of SL-325 in the third quarter of 2025 and complete enrollment in the full Phase 1 by the second quarter of 2026. In a subsequent event, Shattuck announced a securities purchase agreement expected to provide approximately $46 million in upfront gross proceeds upon closing following IND clearance for SL-325, with additional potential proceeds if warrants are exercised.
