This phase II trial tests how well pirtobrutinib and mosunetuzumab work in treating patients with grade 1-3a follicular lymphoma (FL) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Pirtobrutinib, a type of tyrosine kinase inhibitor, works by blocking the action of the Bruton tyrosine kinase (BTK) protein. The BTK protein signals cancer cells to multiply, and blocking it may help keep cancer cells from growing. It could also improve T cell fitness and decrease inflammation, therefore, may improve the efficacy and safety of T cell-based therapies, such as mosunetuzumab. Mosunetuzumab is a bispecific antibody that binds both T cells and the lymphoma cancer cells and harnesses T cells to interfere with the ability of cancer cells to grow and spread. Giving pirtobrutinib and mosunetuzumab together may kill more tumor cells in patients with relapsed or refractory grade 1-3a FL and potentially decreases some side effects of mosunetuzumab which are related to T cells being activated (e.g., cytokine release syndrome).

Article

Author: Zhang, Huilai ; Zhu, Jiankun ; Liu, Yanyan ; Qian, Yijiao ; Zhang, Qingyuan ; Yi, Shuhua ; Zhu, Jun ; Zhang, Liling ; Huang, Huiqiang ; Lin, Ningjing ; Feng, Ru ; Yang, Haiyan ; Song, Yuqin ; Guo, Ye

AbstractPirtobrutinib, a highly selective, noncovalent (reversible) Bruton tyrosine kinase inhibitor (BTKi), demonstrated clinically meaningful antitumor responses in covalent BTKi pretreated mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) in the global phase 1/2 BRUIN study. In this multi‐center, open‐label, phase 2 trial, we investigated the efficacy and safety of pirtobrutinib in Chinese patients with BTKi pretreated relapsed/refractory (R/R) MCL, CLL/SLL, or other B‐cell malignancies. All patients received pirtobrutinib once daily in continuous 28‐day cycles. The primary endpoint was the overall response rate (ORR). Efficacy was assessed in patients with MCL and CLL/SLL with prior BTKi treatment and safety in all enrolled patients who received at least one dose of pirtobrutinib. Among 35 patients with covalent BTKis (cBTKi) pretreated MCL, the ORR was 62.9% (95% CI: 44.9, 78.5), the median duration of response (DOR) was not reached, and the 12‐month DOR rate was 59.7% (95% CI: 35.3, 77.5). Among 11 patients with cBTKi pretreated CLL/SLL, the ORR was 63.6% (95% CI: 30.8, 89.1), and the 12‐month DOR rate was 83.3% (95% CI: 27.3, 97.5). The most common adverse events in the safety population (n = 87) were anemia (32.2%) and neutrophil count decreased (31.0%). Grade ≥3 hemorrhage occurred in 2.3% of patients and there were no cases of atrial fibrillation/flutter. Pirtobrutinib demonstrated clinically meaningful efficacy in Chinese patients with cBTKi pretreated R/R MCL, preliminary antitumor activity in Chinese patients with cBTKi pretreated R/R CLL/SLL and was generally well‐tolerated with no new safety signals observed.

High‐Performance Liquid Chromatography–Ultraviolet Assay for the Determination of Pirtobrutinib Levels in a Patient With Mantle Cell Lymphoma

Article

Author: Shimoda, Mari ; Tukada, Masao ; Gando, Yoshito ; Yasu, Takeo

ABSTRACTPirtobrutinib is a Bruton's tyrosine kinase inhibitor used to treat mantle cell lymphoma and chronic lymphocytic leukemia. Pirtobrutinib has a steady‐state trough concentration of > 825 ng/mL, corresponding to a 90% inhibitory concentration of Bruton's tyrosine kinase. Therefore, maintaining stable trough concentrations of pirtobrutinib is clinically important; however, no methods of monitoring pirtobrutinib levels have been developed. In this study, our aim was to develop a method to determine pirtobrutinib levels in human plasma and validate it for therapeutic drug monitoring. Pirtobrutinib and ibrutinib (internal standard) were separated on a reversed‐phase column using a mobile phase comprising 0.5% KH2PO4 (pH 4.5) and acetonitrile (52:48, v/v) at a flow rate of 1.0 mL/min. Ultraviolet detection was performed at 234 nm. Calibration curves for pirtobrutinib were linear (r2 = 0.9998) in the range of 0.25–10 μg/mL. The intraday and interday validation coefficients were 0.72%–2.86% and 1.29%–3.22%, respectively. This study is the first one to develop and validate a method for quantifying pirtobrutinib in human plasma. These findings may support the widespread application of therapeutic drug monitoring for pirtobrutinib.

Comprehensive Characterization of Bruton’s Tyrosine Kinase Inhibitor Specificity, Potency, and Biological Effects: Insights into Covalent and Noncovalent Mechanistic Signatures

Review

Author: Jahic, Mirza ; Darragh, Antonia C. ; King, Alastair J. ; Hanna, Andrew M. ; Lipner, Justin H. ; Servant, Nicole B.

Uncovering a drug's mechanism of action and possible adverse effects are critical components in drug discovery and development. Moreover, it provides evidence for why some drugs prove more effective than others and how to design better drugs altogether. Here, we demonstrate the utility of a high-throughput in vitro screening platform along with a comprehensive panel to aid in the characterization of 15 Bruton's tyrosine kinase (BTK) inhibitors that are either approved by the FDA or presently under clinical evaluation. To compare the potency of these drugs, we measured the binding affinity of each to wild-type BTK as well as a clinically relevant resistance mutant of BTK (BTK C481S). In doing so, we discovered a considerable difference in the selectivity and potency of these BTK inhibitors to the wild-type and mutant proteins. Some of this potentially contributes to the adverse effects experienced by patients undergoing therapy using these drugs. Overall, noncovalent BTK inhibitors showed stronger potency for both the wild-type and mutant BTK when compared with that of covalent inhibitors, with the majority demonstrating a higher specificity and less off-target modulation. Additionally, we compared biological outcomes for four of these inhibitors in human cell-based models. As expected, we found different phenotypic profiles for each inhibitor. However, the two noncovalent inhibitors had fewer off-target biological effects when compared with the two covalent inhibitors. This and similar in-depth preclinical characterization of drug candidates can provide critical insights into the efficacy and mechanism of action of a compound that may affect its safety in a clinical setting.

Innovent Announces NMPA Approval of Limertinib, a Third-generation EGFR TKI Collaborated with ASK Pharma, for the First-line Treatment of Lung Cancer

SAN FRANCISCO and SUZHOU,China, April 25, 2025 /PRNewswire/ -- Innovent Biologics, Inc. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of oncologic, autoimmune, cardiovascular and metabolic, ophthalmologic and other major diseases, announces that China's National Medical Products Administration (NMPA) has approved the New Drug Application (NDA) for limertinib as the first-line treatment for adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring EGFR exon 19 deletions or exon 21 L858R mutations. Innovent and ASK Pharm entered into a commercial collaboration agreement for limertinib in Mainland China in 2024. The approval of this new indication is supported by positive results from a randomized, double-blind, positive-controlled Phase 3 clinical trial. A total of 337 treatment-naïve patients with EGFR-sensitive mutation-positive locally advanced or metastatic NSCLC were enrolled and randomized 1:1 to receive either limertinib or gefitinib. The primary endpoint was progression-free survival (PFS), as assed by an independent review committee (IRC). The data showed that limertinib significantly prolonged median PFS compared to gefitinib (20.7 months vs. 9.7 months), representing a 56% risk reduction in disease progression or death (hazard ratio [HR] 0.44; 95% CI: 0.34–0.58; p < 0.0001). In patients with central nervous system (CNS) lesions at baseline, median CNS PFS was also significantly longer with limertinib (20.7 months vs. 7.1 months), corresponding to a 72% risk reduction for CNS progression or death (HR 0.28; 95% CI: 0.10–0.82; p = 0.0136), underscoring its robust intracranial activity and clinical utility in such population with high-unmet-needs. The safety profile of limertinib was consistent with that of known EGFR-targeted therapies. Adverse events were predominantly mild to moderate and well-tolerated, with no new safety signals identified during the clinical trial. Full data and analysis from this pivotal Phase 3 study will be published in academic journals. "Limertinib has demonstrated exceptional efficacy and safety as first-line therapy in patients with EGFR-muted locally advanced or metastatic NSCLC, including notable efficacy in those with brain metastases. The approval of this first-line indication introduces a new treatment option for Chinese patients, addressing a critical clinical need in this population." said Professor Shi Yuankai, MD, Department of Medical Oncology at Chinese Academy of Medical Sciences and Principal Investigator of the Phase 3 Clinical Study. Dr. Hui Zhou, Senior Vice President of Innovent, stated："We are delighted that both the first-line and second-line indications for limertinib have been successively approved. As a next-generation EGFR TKI, limertinib is poised to significantly improve survival outcomes for mutation-positive patients. Innovent has built a rich portfolio of precision therapies for lung cancer—including limertinib, Retsevmo®(selpercatinib), Dupert®(fulzerasib) and DOVBLERON® (taletrectinib)—with ongoing efforts to enhance their synergistic value. We will continue to work closely with Ask Pharm to ensure that limertinib brings a new hope to the broad population of patients with EGFR-mutated NSCLC." Mr. Jingfei Ma, CEO of ASK Pharm, stated: "Within a few months, limertinib has obtained approvals for both second-line and first-line indications. The approval of the first-line indication further expands its clinical applicability. Meanwhile, ASK Pharm is advancing a clinical trial of limertinib in combination with the cMET inhibitor ASKC202 for patients with NSCLC resistant to third-generation EGFR-TKIs. We look forward to working with our partner Innovent to accelerate the accessibility of limertinib for more patients in need." About EGFR mutation-positive non-small-cell lung cancer (NSCLC) Lung cancer remains one of the deadliest and most common cancers globally[1], with NSCLC accounting for approximately 85% of cases. Around 70% of NSCLC patients are diagnosed at locally advanced or metastatic stages that are not amenable to surgical resection. EGFR mutations are particularly prevalent among Asian NSCLC patients, affecting 30% to 50% of cases. EGFR-TKIs are the recommended standard of care in the first-line setting, with third-generation EGFR-TKIs offering the broadest treatment applicability. About Limertinib Limertinib is an orally-administrated, third-generation EGFR TKI with proprietary rights. It has been approved by the China's NMPA for: 1) the treatment of adult patients with locally advanced or metastatic EGFR T790M-mutated non-small cell lung cancer (NSCLC), who have previously experienced disease progression during or after treatment with EGFR TKI; and 2) the first-line treatment of adult patients with locally advanced or metastatic NSCLC carrying EGFR exon 19 deletions or exon 21 L858R mutations. In October 2024, Innovent and ASK Pharm entered into a strategic collaboration and license agreement for limertinib in Mainland China.

Innovent Receives NMPA Breakthrough Therapy Designation for IBI363 (PD-1/IL-2α-bias Bispecific Antibody Fusion Protein) in Melanoma

SAN FRANCISCO and SUZHOU, China, March 30, 2025 /PRNewswire/ -- Innovent Biologics, Inc. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of oncology, cardiovascular and metabolic, autoimmune, ophthalmology and other major diseases, announced that the Center for Drug Evaluation (CDE) of China's National Medical Products Administration (NMPA) has granted Breakthrough Therapy Designation (BTD) for IBI363, a first-in-class PD-1/IL-2α-bias bispecific antibody fusion protein, as monotherapy for the treatment of unresectable locally advanced or metastatic mucosal or acral melanoma who have not received prior systemic therapy. Recently, Innovent initiated and dosed the first patient for IBI363 in its first pivotal study to evaluate the efficacy and safety of IBI363 monotherapy versus pembrolizumab (Keytruda®) monotherapy in patients with unresectable, locally advanced or metastatic mucosal or acral melanoma who have not received prior systemic therapy. Furthermore, IBI363 has received two fast track designations (FTD) from the U.S. Food and Drug Administration (FDA), for the treatment of squamous non-small cell lung cancer and melanoma, respectively. IBI363 has demonstrated outstanding efficacy signals in immunotherapy (IO)-naïve melanoma patients across two earlier clinical trials (Phase 1a/1b study NCT05460767 and Phase 2 study NCT06081920), which enrolled a total of 26 patients with advanced acral or mucosal melanoma: The overall objective response rate (ORR) was 61.5%, and the disease control rate (DCR) was 84.6%—significantly higher than current domestic immunotherapy standards. Prolonged follow-up revealed sustained tumor responses and long-term benefits, suggesting the potential superiority of IBI363 over existing standard therapies. Dr. Hui Zhou, Senior Vice President of Innovent, said, "As Innovent's first-in-class next-generation IO therapy, IBI363 simultaneously and selectively inhibits the PD-1/PD-L1 pathway and activates the IL-2 pathway. IBI363 has recently received multiple FTD and BTD designations, signifying regulatory recognition of its clinical value in addressing unmet medical needs. Non-cutaneous melanoma subtypes like mucosal melanoma—which are more prevalent in China—are particularly resistant to immunotherapy with limited clinical benefits[i]. We aim to validate IBI363's potential in its first pivotal trial, through a head-to-head comparison with pembrolizumab, as a superior treatment option for melanoma patients over the current standard-of-care. We are also accelerating the global development of IBI363 across multiple tumor types, with the goal of extending the benefits of China's innovation to patients worldwide." NMPA Breakthrough Therapy Designation is intended to facilitate and expedite the development and review of investigational drugs for serious diseases or conditions when preliminary clinical evidence indicates substantial improvement over current therapies. BTD qualifies a drug candidate for accelerated review by the CDE and provides the sponsor with timely advice and communication to expedite the approval process, helping to address the unmet clinical needs of patients more swiftly. About IBI363 (First-in-class PD-1/IL-2α-bias bispecific antibody fusion protein) IBI363 is a first-in-class drug candidate independently developed by Innovent Biologics. It is a PD-1/IL-2 bispecific antibody fusion protein designed to enhance efficiency while minimizing toxicity. The IL-2 arm of IBI363 has been engineered to optimize therapeutic effects with reduced side effects, while the PD-1 binding arm enables PD-1 blockade and selective IL-2 delivery. By simultaneously inhibiting the PD-1/PD-L1 pathway and activating the IL-2 pathway, IBI363 facilitates more precise and efficient targeting and activation of tumor specific T cells. Preclinical studies have shown that IBI363 exhibits strong anti-tumor activity across multiple tumor-bearing pharmacological models, including those resistant to PD-1 inhibitors and metastatic models. Additionally, it has demonstrated a favorable safety profile in preclinical models. Clinical trials of IBI363 are currently underway in China, the United States, and Australia to evaluate its safety, tolerability and preliminary efficacy in subjects with advanced malignancies. The first pivotal study of IBI363 has been initiated, for the treatment of IO-naive mucosal or acral melanoma. Furthermore, IBI363 has received two fast track designations (FTD) from the U.S. FDA, for the treatment of melanoma and squamous NSCLC, respectively. IBI363 has also received breakthrough therapy designation from the NMPA of China for the treatment of melanoma. About Melanoma Melanoma is a malignant tumor that develops from melanocytes. Although melanoma accounts for only 3% of all types of skin cancer, it has the highest mortality rate of all types and is the most likely to metastasize. In China, the incidence and mortality rate of melanoma continue to rise. Melanoma is classified into three main subtypes: cutaneous, acral and mucosal. The characteristics of melanoma in Chinese patients differs greatly from those seen in European and American Caucasian populations in terms of pathogenesis, biological behavior, histological morphology, treatment response and prognosis[i]. For advanced cutaneous and acral melanomas, patients with the BRAF V600 mutation typically receive BRAF inhibitor combined with MEK inhibitors as the preferred molecular targeted therapy. For those without the BRAF V600 mutation, chemotherapy combined with anti-angiogenic drugs can be is a first-line treatment option. Notably, pembrolizumab has been approved as the first-line treatment indication for advanced melanoma in September 2024 in China, although clinical benefits are limited. For second-line treatment, therapies not previously used in first-line settings are recommended. Patients who have not received PD-1 monoclonal antibody in the first-line setting may be treated with PD-1 inhibitors as a second-line option. For advanced mucosal melanoma -which are more prevalent in China-are particularly resistant to immunotherapy with limited clinical benefits, in urgent need of new treatment options.
