Analysis · XLO · Life Sciences
A pivotal regulatory step—FDA clearance of the IND for XTX501, a bispecific PD-1/masked IL-2—headlines Xilio Therapeutics' Q2 2026 update. The financial picture strengthened with $136.0 million in cash, collaboration revenue of $18.7 million fueled by AbbVie and Gilead partnerships, and a net loss that narrowed to $6.4 million. With runway now projected into Q1 2028, the company is well-positioned to advance its masked T cell engager pipeline. For a clinical-stage biotech, the IND clearance and upcoming first-in-human dosing later this year mark material progress.
