BostonGene and Leading Global Cancer Institutions Announce Nature Publication

Integrated multiomic molecular analyses reveal key gene expression patterns and tumor evolution dynamics, predicting improved outcomes and reduced toxicity from combination therapy in patients with relapsed/refractory T-cell lymphomas

WALTHAM, Mass.--(BUSINESS WIRE)--BostonGene, a leading provider of AI-based molecular and immune profiling solutions, and researchers from multiple cancer centers including, Memorial Sloan Kettering Cancer Center, Dana-Farber Cancer Institute, Weill Cornell Medicine and Washington University School of Medicine in St. Louis and others, today announced the online publication of the manuscript “Deep Clinical Responses and Limited Inflammatory Toxicity in Patients with Relapsed/Refractory T-cell Lymphomas Receiving Duvelisib and Romidepsin”* in Nature Medicine. The study highlights significant clinical responses and reduced inflammatory toxicity in patients with relapsed and refractory T-cell lymphomas treated with a combination of duvelisib and romidepsin.

Historically, PI3K inhibitors have been associated with autoimmune and infectious toxicities, often leading to market withdrawals. Researchers from multiple leading cancer centers had previously demonstrated single-agent activity of the PI3K-γδ inhibitor duvelisib in T-cell lymphomas, although inflammatory adverse events were noted. Based on this preliminary work, a new phase 1b/2a clinical trial was launched to investigate the safety and efficacy of duvelisib in combination with either romidepsin or bortezomib in patients with relapsed/refractory T-cell lymphomas. Combining duvelisib and romidepsin significantly improved treatment outcomes in patients with peripheral T-cell lymphomas (PTCL).

To explore tumor molecular features that may be linked to therapeutic response to this novel therapeutic combination, BostonGene performed DNA whole exome (WES) and RNA transcriptome (RNAseq) sequencing on both pre-treatment and on-treatment biopsies. BostonGene then performed integrated multi-omic molecular analyses, including cellular deconvolution, mutational landscape analyses, longitudinal genetic reconstruction to study tumor evolution, and deciphering immune microenvironment dynamic changes. BostonGene uncovered that PTCL patients with a follicular helper T-cell subtype showed increased response rates to the combination and identified gene expression patterns potentially linked to therapeutic resistance.

“Our findings offer a promising new approach for treating patients with relapsed and refractory T-cell lymphomas, specifically those with the follicular helper T-cell subtype. We are excited about the potential of this combination therapy to improve patient outcomes and expand treatment options in this challenging disease,” said Nathan Fowler, MD, Chief Medical Officer at BostonGene.
