• Clinical Milestones Set

  First patient enrollment is expected by the end of 2026, with initial proof-of-concept data anticipated in the second half of 2027.

• Strong Cash Position

With the FDA's clearance of the IND for ATR 1072, Atrium's lead program enters human testing for the first time—a major derisking milestone for a preclinical biotech. The company now has a clinical-stage asset targeting a disease with no approved therapies. Concrete milestones come from the Corventis trial design (37 patients, Phase 1/2) and timelines: first patient by end of 2026, proof-of-concept data in H2 2027. Bolstered by $267.8 million in cash as of Q1 2026, Atrium is well-funded to reach these data readouts without near-term dilution risk.
