Abstract:
This registration study assessed clinical outcomes of TQ-B3525, the dual phosphatidylinositol-3-kinase (PI3K) α/δ inhibitor, in relapsed and/or refractory follicular lymphoma (R/R FL). This phase II study (ClinicalTrials.gov NCT04324879. Registered March 27, 2020) comprised run-in stage and stage 2. R/R FL patients after ≥2 lines therapies received oral 20 mg TQ-B3525 once daily in a 28-day cycle until intolerable toxicity or disease progression. Primary endpoint was independent review committee (IRC)-assessed objective response rate (ORR). Based on results (ORR, 88.0%; duration of response [DOR], 11.8 months; progression-free survival [PFS], 12.0 months) in 25 patients at run-in stage, second stage study was initiated and included 82 patients for efficacy/safety analysis. Patients received prior-line (median, 3) therapies, with 56.1% refractory to previous last therapies; 73.2% experienced POD24 at baseline. At stage 2, ORR was 86.6% (71/82; 95% CI, 77.3–93.1%), with 28 (34.2%) complete responses. Disease control rate was 95.1% due to 7 (8.5%) stable diseases. Median time to response was 1.8 months. Among 71 responders, median DOR was not reached; 18-month DOR rate was 51.6%. with median follow-up of 13.3 months, median PFS was 18.5 (95% CI, 10.2-not estimable) months. Median overall survival (OS) was not reached by cutoff date; 24-month OS rate was estimated as 86.1%. Response rates and survival data were consistent across all subgroups. Grade 3 or higher treatment-related adverse events were observed in 63 (76.8%) cases, with neutropenia (22.0%), hyperglycemia (19.5%), and diarrhea (13.4%) being common. TQ-B3525 showed favorable efficacy and safety for R/R FL patients after ≥2 lines prior therapies.

Abstract:
Background:
Phosphatidylinositol 3‐kinase (PI3K) inhibitors transformed management of various malignancies. This study preclinically characterized TQ‐B3525 (dual PI3Kα/δ inhibitor) and assessed the recommended phase 2 dose (RP2D), safety, efficacy, and pharmacokinetics in relapsed or refractory (R/R) lymphoma or advanced solid tumors (STs).
Methods:
Oral TQ‐B3525 was given at eight dose levels on a 28‐day cycle. Primary end points were dose‐limiting toxicity (DLT), maximum tolerated dose (MTD), and safety.
Results:
TQ‐B3525 showed high selectivity and suppressed tumor growth. Between June 12, 2018, and November 18, 2020, 80 patients were enrolled (63 in dose‐escalation cohort; 17 in dose‐expansion cohort). Two DLTs occurred in two (two of 63, 3.2%) DLT‐evaluable patients; MTD was not identified. TQ‐B3525 at 20 mg once daily was selected as RP2D. Grade 3 or worse treatment‐related adverse events mainly included hyperglycemia (16.3%), neutrophil count decreased (15.0%), and diarrhea (10.0%). Two (2.5%) treatment‐related deaths were reported. Sixty patients with R/R lymphoma and 11 advanced STs demonstrated objective response rates of 68.3% and 9.1%, disease control rates of 91.7% and 54.6%, median progression‐free survivals of 12.1 and 1.1 months; median overall survivals were not reached.
Conclusion:
TQ‐B3525 exhibited rapid absorption and a nearly proportional increase in exposure. Acceptable safety and promising efficacy support further investigation of TQ‐B3525 (20 mg once daily) for R/R lymphoma.

Predict the Drug–Drug Interaction of a Novel PI3Kα/δ Inhibitor, TQ‐B3525, and Its Two Metabolites Using Physiologically Based Pharmacokinetic Modeling
Article
作者: Yu, Ding ; Wang, Xin ; Wang, Xunqiang ; Zhu, Shixing
Abstract:
A novel dual PI3K α/δ inhibitor, TQ‐B3525, has been developed for the targeted treatment of lymphoma and solid tumors. TQ‐B3525 is primarily metabolized by CYP3A4 and FOM3, while also serving as a substrate for the P‐glycoprotein transporter. The aim of this study was to anticipate the drug–drug interaction (DDI) of TQ‐B3525 and its two metabolites with CYP3A4 enzyme potent inducer (rifampicin) and CYP3A4/P‐gp inhibitor (itraconazole) utilizing a physiologically based pharmacokinetic (PBPK) modeling approach. Clinical data from healthy and cancer patient adults were employed to construct and evaluate the PBPK model for TQ‐B3525, M3, and M8‐3. Models involving rifampicin combined with midazolam, itraconazole combined with midazolam or digoxin were utilized to showcase the robustness of evaluating DDI effects. The simulated drug exposure of TQ‐B3525, M3, and M8‐3 in healthy and patient adults were consistent with clinical data, and the mean fold error values were within the acceptable ranges. The simulated results of positive substrates correspond to those reported in the literature. Co‐administration with rifampicin reduces Cmax and AUC of TQ‐B3525 to 76.1% and 46.0%, while increasing the levels of M3 and M8‐3. With itraconazole, Cmax and AUC of TQ‐B3525 rise to 131% and 204%, but decrease substantially for M3 and M8‐3. PBPK model simulation results showed that the systemic exposure of TQ‐B3525 was significantly affected when co‐administered with CYP3A4/P‐gp inducers and inhibitors. This indicates that the combination with strong inducers and inhibitors should be carefully avoided or adjust the dosage of TQ‐B3525 in clinic.
