Identifying therapeutic targets in low-grade serous ovarian carcinomas with no specific molecular profile. (PubMed, J Pathol) - "EGFR inhibitors emerged as selective hits in NSMP cell lines and were further tested in two NSMP and two MAPK-mutant lines in combination with standard-of-care chemotherapy agents, carboplatin and paclitaxel...EGFR inhibitors (avitinib, AV-412) showed selective, low-dose synergy with standard-of-care chemotherapy in NSMP models, with minimal and inconsistent effects in MAPK-mutant lines...These findings position EGFR overexpression as a defining and targetable feature of NSMP LGSOC and support further preclinical validation of EGFR inhibitors as a treatment strategy for this understudied cancer subtype."

Systematic Proteomic Characterization of EV-A71-Infected Mice Identifies Dynamic Molecular Changes and Therapeutic Targets. (PubMed, MedComm (2020)) - "We found that kinase inhibitors have antiviral activity in vitro; vandetanib, nintedanib, dasatinib, avitinib, and nilotinib can inhibit virus replication in mice to some extent. Overall, this study provides a multi-omics resource for elucidating EV-A71-induced alterations in target tissues and for linking omics-based target discovery with drug screening and functional validation, providing new insights into both pathogenesis and therapeutic exploration."

In vitro metabolism studies of 5 acrylamide covalent drugs: Comparison with metabolism and disposition in human. (PubMed, Drug Metab Dispos) - "By comparing in vitro metabolic data for abivertinib, afatinib, osimertinib, ibrutinib, and pyrotinib with reported human metabolism and disposition data, we demonstrated that this method improves the accuracy of predicting CYP-mediated metabolic rates. Furthermore, it provides clearer insights into the relative contributions of CYP metabolism, nonspecific protein covalent binding, and glutathione adduction to the overall metabolic clearance of acrylamide covalent drugs in humans."

Practical Application of Orelabrutinib in Patients with Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL): Analysis of Real-World Evidence (OCARE Study) (ASH 2024) - "20.8% (16/77) of the patients who had previously been treated with BTK inhibitors, including ibrutinib, zanubrutinib, avitinib and SS-001, switched to orelabrutinib due to AE intolerance or unsatisfactory efficacy.Median follow-up time was 9.8 months (range, 0.7-25.7). No unexpected adverse events were reported.Conclusion : The study demonstrates that orelabrutinib elicits robust hematological responses in both newly diagnosed and relapsed/refractory CLL/SLL patients, with an acceptable safety profile and a prolonged DOT. Although limited by its sample size, the data provide compelling evidence that orelabrutinib is a promising therapeutic option for CLL/SLL patients."

Development and validation of a deep learning-based model to predict response and survival of T790M mutant non-small cell lung cancer patients in early clinical phase trials using electronic medical record and pharmacokinetic data. (PubMed, Transl Lung Cancer Res) - "We utilized the electronic medical record (EMR) and pharmacokinetic parameters of 326 T790M-mutated NSCLC patients, including 283 patients treated with Abivertinib in phase I (n=177, for training) and II (n=106, for validation) clinical trials and an additional validation cohort 2 comprising 43 patients treated with BPI-7711. CoxMoE offers a valuable approach for patient selection by forecasting therapeutic response and PFS utilizing laboratory tests and pharmacokinetic parameters in the setting of early-phase clinical trials. Simultaneously, CoxMoE could predict the efficacy of third-generation EGFR-TKI non-invasively for T790M-positive NSCLC patients, thereby complementing existing EGFR genotype detection."

Antifibrotic mechanism of avitinib in bleomycin-induced pulmonary fibrosis in mice. (PubMed, BMC Pulm Med) - "At present, only two drugs are approved by the FDA for the treatment of IPF, including the synthetic pyridinone drug, pirfenidone, and the tyrosine kinase inhibitor, nintedanib. The cellular experiments also indicated that avitinib improved alveolar epithelial cell injury in A549 cells. In conclusion, the present findings demonstrated that avitinib attenuates bleomycin-induced pulmonary fibrosis in mice by inhibiting alveolar epithelial cell injury and myofibroblast activation."

Trial to evaluate TKI and abiraterone treatment combination for prostate cancer (Urology Times) - "MAVERICK, a phase 2, open-label clinical trial (NCT05361915) to evaluate the efficacy of a new prostate cancer treatment combination of abivertinib and abiraterone acetate (Zytiga), is now underway across 9 sites in the US....The treatment combination was based on findings from research that investigated the process through which prostate cancer synthesizes androgens. Results showed that a tyrosine kinase called BMX interacted with the enzyme produced by HSD2B1....Further research with preclinical models found that knocking out BMX or halting phosphorylation stopped androgen production and cancer growth. These findings identified BMX as the therapeutic target, resulting in the therapy combination in MAVERICK."

Identification of LRRK2 Inhibitors through Computational Drug Repurposing. (PubMed, ACS Chem Neurosci) - "The experimental results showed six drugs (Abivertinib, Aumolertinib, Encorafenib, Bosutinib, Rilzabrutinib, and Mobocertinib) with IC less than 5 μM that were identified as potential LRRK2 kinase inhibitors. In summary, the results showed that our drug repurposing workflow could be used to identify potent compounds for LRRK2. The potent inhibitors discovered in our work can be a starting point to develop more effective LRRK2 inhibitors."

Overview of the multifaceted resistances toward EGFR-TKIs and new chemotherapeutic strategies in non-small cell lung cancer. (PubMed, Biochem Pharmacol) - "However, patients treated with third-generation TKIs (osimertinib, avitinib and rociletinib) targeting the EGFR T790M mutation have shown emerging resistances and relapses. This will pave the way for designing novel and effective chemotherapies to improve patients' overall survival. In this review, we provide an overview of the multifaceted mechanism of resistances towards EGFR-TKIs, as well as the challenges and perspectives that should be addressed in strategising chemotherapeutic treatments to overcome the ever evolving and adaptive nature of NSCLC."

Sorrento Announces Significant Positive Pivotal Trial Results as Assessed by an Independent Review Committee (IRC) With Matured Long-Term (Over Three Years) Follow-Up Data of Abivertinib for the Treatment of Advanced Non-Small Cell Lung Cancer (NSCLC) (GlobeNewswire) - P1/2 | N=368 | NCT02330367 | Sponsor: Hangzhou ACEA Pharmaceutical Research Co., Ltd | "In these IRC-assessed preliminary topline results with more matured long-term follow up data (previously 16.8 months, now 38.8 months), Abivertinib showed significant treatment benefits in 209 response evaluable, heavily treated NSCLC patients with ORR of 56.5%, and notably a significant CR rate was seen with Abivertinib (5.3%) in comparison with that of osimertinib (Tagrisso) (0.5%)*, while the ORR rate is comparable between the two drugs. This combined data, the ORR of 56.5%, the CR rate of 5.3%, and median OS of 28.2 month (versus Tagrisso’s median OS of 26.8 months), is potentially superior to that of the approved third generation EGFR inhibitor (osimertinib)...Based on these results, Sorrento is closing the study and preparing the pre-NDA materials and NDA package."
