Is this trial a fit for you?
✓Likely a good fit
Adults (≥18 years) with relapsed or refractory hematologic malignancies who have measurable disease, ECOG ≤2, have exhausted standard therapies, and are not receiving other anti-cancer treatments are the intended candidates.
✕Probably not a fit
Patients with active graft-versus-host disease requiring immunosuppression, uncontrolled medical conditions, recent major surgery, bleeding, significant cardiac impairment, or those receiving other anti-cancer therapies are unlikely to benefit from participation.

What this trial studies
This is a Phase 1, open-label, single-agent trial giving trichostatin A to adults with relapsed or refractory hematologic malignancies to characterize safety and tolerability. Participants must have measurable or evaluable disease, an ECOG performance status of 0–2, and have exhausted available standard therapies. Study procedures include regular clinical exams, laboratory monitoring, cardiac monitoring, and disease assessments to track adverse events and any signs of response. The trial is conducted at Vanda investigational sites and will follow participants through dosing and predefined safety follow-up periods.
Why it matters
Potential benefit: If tolerated and safe, this drug could offer a new treatment option or lead to later trials testing its effectiveness in certain blood cancers.
How similar studies have gone: Other histone deacetylase inhibitors have shown activity and have approvals for some hematologic cancers, but trichostatin A itself is largely preclinical with limited clinical data, making this an early-stage effort.
