Dual targeting of PI3Kδ and PPARα enhances antitumor activity via FoxO1 activation in follicular lymphoma. (PubMed, Cell Death Dis) - "Here, we show that combining the PI3Kδ inhibitor linperlisib with the pan-peroxisome proliferator-activated receptor (PPAR) agonist chiglitazar, an agent that reprograms tumor metabolism, delivers robust antitumor activity across FL models, including cell-derived and patient-derived xenografts, with a favorable tolerability profile. Compared with monotherapy, the combination consistently achieves superior tumor control in vivo without overt toxicity, supporting its clinical translation potential. Collectively, these data provide a mechanistic rationale for dual targeting of PI3Kδ and PPARα in FL and advocate for clinical evaluation of this combination with FoxO1 as a pharmacodynamic biomarker."

Synergistic Remission of refractory cutaneous T-cell lymphoma by linperlisib plus venetoclax via targeting the PI3K/AKT/CREB-BCL-2/MCL-1 signaling axis. (ASH 2025) - " We report a 67-year-old woman with multiply relapsed pcALCL refractory to CHOP, CHOP plus brentuximab vedotin (BV), and three courses of total skin electron beam therapy (TSEBT), who subsequently initiated combination therapy with linperlisib (PI3Kδ inhibitor) and venetoclax (BCL-2 inhibitor). In this case, dual PI3Kδ and BCL-2 blockade achieved durable remission after failure of all conventional therapies. Linperlisib suppresses BCL-2/MCL-1 expression by inhibiting the PI3K/AKT/CREB axis, synergizing with venetoclax to overcome resistance. This combination represents a novel therapeutic strategy for achieving durable remission in relapsed pcALCL."

PIM1 mutation drives ANXA2 membrane relocalization and promotes lymphomagenesis through PI3K/AKT/mTOR pathway in DLBCL (ASH 2025) - "In particular, thePIM1L184F mutation promoted cell proliferation and was resistant to doxorubicin in vitro and showedfaster tumor growth in vivo. Additionally, the high-throughput drug screening demonstrated thatthe PIM1L184F mutated cells were more sensitive to the PI3K inhibitor YY20394. PIM1 inhibitor SMI-4acombined with YY20394 showed synergistic antitumor effects both in vitro and in vivo.ConclusionsTaken together, these findings not only shed light on an innovative regulatory mechanismfor how PIM1L184F mutation contributes to the pathogenesis of DLBCL but also provide a potentialtherapeutic strategy for effectively managing DLBCL patients harboring PIM1L184F mutation."

Venetoclax Enhances Human Γδt Cells Anti-Leukemia Immunity through Metabolic Reprogramming (ASH 2024) - "Results : Among several pharmacological agents, such as Venetoclax, Enasidenib, Azacytine, Selinexor, Decitabine, Chidamise, Linperlisib and Cytarabine, Venetoclax treatment significantly enhanced the anti-tumor efficacy of γδT cells against the γδT cell-resistant AML cell line and patient-derived cells, achieving a 49.21% killing efficiency in venetoclax-treated γδT cells compared to 5.06% with untreated cells. The ability of venetoclax to potentiate the natural cytotoxic functions of γδT cells and promote a metabolic state conducive to long-lasting cytotoxicity offers a dual mechanism of action that could overcome some of the traditional challenges faced in targeting AML. The convergence of cellular therapy with targeted drug treatment, as evidenced by the efficacy of venetoclax in our research, represents a novel and exciting direction in cancer immunotherapy."

Dose Adjustments of Linperlisib in Relapsed or Refractory Follicular Lymphoma: A Post-Hoc Analysis of a Pivotal Phase II Study (ASH 2023) - "Our post-hoc analysis reveals that elderly patients (≥60 years old) have reduced tolerance to linperlisib, necessitating more frequent dose adjustments due to AEs. Notably, treatment discontinuation results in inferior DOR and PFS, while dose adjustments or suspensions yield comparable DOR and PFS to full-dose treatment, suggesting that tolerability-guided dose modification effectively reduces AEs without sacrificing therapeutic efficacy."
