Combining linperlisib and chidamide for treating peripheral T-cell lymphoma

PI3Kδ Inhibitor Linperlisib Combined With HDAC Inhibitor Chidamide Versus CHOP in Patients With Peripheral T-cell Lymphoma: a Multicenter, Open Label, Phase Ib/II Study

Phase1; Phase2 Interventional Henan Cancer Hospital · NCT06421948

This study is testing a new combination of two drugs, linperlisib and chidamide, to see if it can help people with peripheral T-cell lymphoma more than the usual chemotherapy treatment.

What this trial studies

This clinical trial aims to determine the maximum tolerated dose of the PI3Kδ inhibitor linperlisib when combined with the HDAC inhibitor chidamide in patients with peripheral T-cell lymphoma (PTCL). The study consists of a phase Ib trial where participants will receive a fixed dose of chidamide alongside escalating doses of linperlisib to identify the optimal dosage. Following this, a phase II trial will randomize newly diagnosed PTCL patients to receive either the combination treatment or the standard CHOP chemotherapy regimen. Efficacy assessments will be conducted after three cycles of treatment to evaluate the response.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-75 with newly diagnosed or relapsed/refractory peripheral T-cell lymphoma.

Not a fit: Patients with anaplastic large cell lymphoma or NK/T-cell lymphoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this combination therapy could offer a more effective treatment option for patients with peripheral T-cell lymphoma.

How similar studies have performed: Other studies have shown promise in using combination therapies for lymphoma, but this specific combination is novel.
