Real-World Data of Triplet Combination of Trastuzumab, Lapatinib, and Chemotherapy in HER2-Positive Metastatic Breast Cancer: A Multicenter Retrospective Study

4 views | Mar 29 2020

Li Y et al. indicated that TLC demonstrated promising effects and tolerable safety in HER2+MBC, even in patients with BM, providing a theoretical basis for clinical practice. [Read the Full Post]

Molecular alterations and poziotinib efficacy, a pan-HER inhibitor, in human epidermal growth factor receptor 2 (HER2)-positive breast cancers: Combined exploratory biomarker analysis from a phase II clinical trial of poziotinib for refractory HER2-positive breast cancer patients

14 views | Mar 11 2020

Koga T et al. identified HER2 CN amplification, PIK3CA pathway alteration, and ERBB3 cytoplasmic mutation showed predictive roles on clinical outcomes of HER2-positive MBC treated with poziotinib. [Read the Full Post]

Activity of a novel HER2 inhibitor, poziotinib, for HER2 exon 20 mutations in lung cancer and mechanism of acquired resistance: An in vitro study

19 views | Mar 10 2020

Koga T et al. identified the secondary C805S at the covalent binding site of HER2 to poziotinib as a potential mechanism of acquired resistance. HSP90 inhibitors might be a therapeutic strategy for the C805S secondary mutation. [Read the Full Post]

Phase I Dose-Escalation Study of the pan-HER Inhibitor, PF299804, in Patients With Advanced Malignant Solid Tumors

16 views | Mar 02 2020

Pasi A Jänne et al. showed the MTD of PF299804 is 45 mg/d. Both continuous and intermittent treatment schedules were well tolerated, and encouraging signs of antitumor activity were observed in gefitinib/erlotinib treated NSCLC patients. [Read the Full Post]

Administration of Lapatinib with Food Increases Its Plasma Concentration in Chinese Patients with Metastatic Breast Cancer: A Prospective Phase II Study

27 views | Feb 16 2020

Xu F et al. showed that receiving lapatinib with food can increase its plasma concentration with no significantly increased drug-related toxicity. We suggest that a larger-sample-size clinical trial is needed to fully understand the effect of administration of lapatinib with food. [Read the Full Post]

Determination of Somatic Mutations and Tumor Mutation Burden in Plasma by CAPP-Seq during Afatinib Treatment in NSCLC Patients Resistance to Osimertinib

38 views | Feb 01 2020

Ishii H et al. demonstrated that detection of mutant allele frequency and TMB of ctDNA by CAPP-Seq could help determine the effectiveness of and resistance to afatinib. [Read the Full Post]

Treatment outcome and clinical characteristics of HER2 mutated advanced non-small cell lung cancer patients in China

41 views | Feb 01 2020

Fei Xu et al. found that HER2 mutated lung cancer patients were younger, mostly females, never or light smokers, with histologically diagnosed adenocarcinomas. Compared with afatinib, chemotherapy might bring more benefit to HER2 mutated advanced lung cancer patients, especially the most common type of HER2 exon 20 insertions, A775_G776insYVMA subtype.

The development of HKI-272 and related compounds for the treatment of cancer

64 views | Dec 22 2019

Wissner A et al. highlight the findings that these irreversible inhibitors retain activity against tumors that have acquired a resistance to the reversible binding inhibitors gefitinib and erlotinib. The promising interim clinical trial results for HKI-272 and EKB-569 in treating colon, lung, and breast cancers are summarized. [Read the Full Post]

The Potent ALK Inhibitor Brigatinib (AP26113) Overcomes Mechanisms of Resistance to First- and Second-Generation ALK Inhibitors in Preclinical Models

142 views | Nov 02 2019

Zhang S et al. provided the molecular basis for the promising activity being observed in ALK+, crizotinib-resistant patients with NSCLC being treated with brigatinib in clinical trials. [Read the Full Post]

Lapatinib Resistance in Breast Cancer Cells Is Accompanied by Phosphorylation-Mediated Reprogramming of Glycolysis

173 views | Oct 15 2019

Ruprecht B et al. offered deeper perspectives on cancer drug resistance and suggests new biomarkers and treatment options for lapatinib-resistant cancers. [Read the Full Post]
