Giotrif® (afatinib) approved in Europe as new oral treatment option for patients with squamous cell carcinoma of the lung

On April 7, 2016 Boehringer Ingelheim reported that the European Commission (EC) has granted marketing authorisation for Giotrif (afatinib) for the treatment of patients with advanced squamous cell carcinoma (SqCC) of the lung whose disease has progressed on or after treatment with platinum-based chemotherapy(Press release, Boehringer Ingelheim, APR 6, 2016, View Source [SID:1234510494]). Afatinib is already approved for the treatment of patients with EGFR mutation-positive non-small cell lung cancer (NSCLC).*

Dr. Mehdi Shahidi, Medical Head, Solid Tumour Oncology, Boehringer Ingelheim commented: "Whilst there have been some recent and significant advances in the treatment of squamous cell carcinoma of the lung, the intravenous administration and frequent visits to the hospital can be a challenge for patients often debilitated by this disease. In this context and supported by robust evidence from a Global head-to-head Phase III study, we are pleased to offer an effective oral treatment option for patients suffering from this type of lung cancer to the European market."

SqCC of the lung is associated with a poor prognosis, limited survival and symptoms like cough and dyspnoea. The median overall survival (OS) after diagnosis of advanced SqCC is around one year.4,5

The marketing authorisation in Europe is valid for 28 countries within the EU. The EU regulatory submission was based on results of the head-to-head LUX-Lung 8 trial in patients with SqCC of the lung whose tumours progressed on or after first-line chemotherapy. Afatinib, compared to erlotinib, demonstrated:3

Significant delay in progression of lung cancer (PFS, progression-free survival, primary endpoint), reducing the risk of cancer progression by 19%
Significant improvement in overall survival (OS, key secondary endpoint), reducing the risk of death by 19%
Significantly improved disease control rate (51% vs 40%; P=0.002)
An improvement in quality of life and control of cancer symptoms
The rate of severe adverse events was similar between the two treatment arms with differences observed in the incidence of certain side effects: a higher incidence of severe diarrhoea and stomatitis (mouth sores) was observed with afatinib compared to erlotinib (grade 3 diarrhoea: 10% vs 2%; grade 3 stomatitis: 4% vs 0%), while a higher incidence of severe rash/acne was reported with erlotinib compared to afatinib (grade 3 rash/acne: 10% vs 6%).3

LUX-Lung 8 (NCT01523587) is part of the afatinib LUX-Lung programme – the largest collection of clinical trials of any EGFR tyrosine kinase inhibitor (TKI), with over 3,760 patients across eight studies conducted across the world. The comprehensive LUX-Lung programme includes two pivotal studies in the first-line setting for EGFR mutation-positive patients, LUX-Lung 3 and 6 which compared afatinib to chemotherapy regimens. In addition, the programme included two head-to-head studies (LUX-Lung 7 and 8) of afatinib versus first-generation EGFR TKIs. The LUX-Lung programme has involved over 680 sites in 40 countries, reflecting the strong partnership between Boehringer Ingelheim and the lung cancer specialist community.

Afatinib is already approved in over 60 countries for the first-line treatment of EGFR mutation-positive NSCLC*, and recent results from the LUX-Lung 7 trial positively underscore the benefits of afatinib versus gefitinib, another first-generation EGFR targeting agent in this indication.6 Results of this global Phase IIb head-to-head trial demonstrated afatinib was superior in reducing the risk of lung cancer progression and the risk of treatment failure both by 27% compared to gefitinib.6

For more information about the LUX-Lung 8 trial, please see Professor Jean-Charles Soria’s publication in The Lancet Oncology

*Afatinib is approved in the EU under the brand name GIOTRIF for the first-line treatment of TKI naïve adult patients with advanced EGFR mutation-positive NSCLC. In April 2016 afatinib was approved by the European regulatory authority as a second-line treatment for SqCC of the lung. Registration conditions differ internationally, please refer to locally approved prescribing information.

About Niraparib

Niraparib is an oral, once daily, potent, and highly selective PARP inhibitor that induces synthetic lethality in tumors cells with homologous recombination DNA repair deficiencies (HRD). The ongoing development program for niraparib includes a Phase 3 trial in patients with ovarian cancer (the NOVA trial), a registrational Phase 2 treatment trial in patients with ovarian cancer (the QUADRA trial), and a Phase 3 trial for the treatment of patients with BRCA-positive breast cancer (the BRAVO trial). In addition, a Phase 3 trial of niraparib in first-line ovarian cancer (PRIMA) and a Phase 1/2 clinical trial designed to evaluate the combination of niraparib plus KEYTRUDA (pembrolizumab) in patients with triple-negative breast cancer or ovarian cancer are planned to initiate shortly. Several collaborator-sponsored studies are also underway, including combination trials of niraparib plus enzalutamide, bevacizumab, and temozolomide, in patients with prostate cancer, ovarian cancer, and Ewing’s sarcoma, respectively. Additional studies are being planned to evaluate niraparib in patients with lung cancer.

PKM2 Thr454 phosphorylation increases its nuclear translocation and promotes xenograft tumor growth in A549 human lung cancer cells.

Pyruvate kinase M2 (PKM2) is a key enzyme of glycolysis which is highly expressed in many tumor cells, and plays an important role in the Warburg effect. In previous study, we found PIM2 phosphorylates PKM2 at Thr454 residue (Yu, etl 2013). However, the functions of PKM2 Thr454 modification in cancer cells still remain unclear. Here we find PKM2 translocates into the nucleus after Thr454 phosphorylation. Replacement of wild type PKM2 with a mutant (T454A) enhances mitochondrial respiration, decreases pentose phosphate pathway, and enhances chemosensitivity in A549 cells. In addition, the mutant (T454A) PKM2 reduces xenograft tumor growth in nude mice. These findings demonstrate that PKM2 T454 phosphorylation is a potential therapeutic target in lung cancer.

Altered expression and splicing of ESRP1 in malignant melanoma correlates with epithelial-mesenchymal status and tumor-associated immune cytolytic activity.

Melanoma is one of the major cancer types for which new immune-based cancer treatments have achieved promising results. However, anti-PD-1 and anti-CTLA-4 therapies are effective only in some patients. Hence, predictive molecular markers for the development of clinical strategies targeting immune checkpoints are needed. Using the Cancer Genome Atlas (TCGA) RNAseq data, we found expression of ESRP1, encoding a master splicing regulator in the epithelial-to-mesenchymal transition (EMT), was inversely correlated with tumor-associated immune cytolytic activity. That association holds up across multiple TCGA tumor types, suggesting a link between tumor EMT status and infiltrating lymphocyte activity. In melanoma, ESRP1 mainly exists in a melanocyte-specific truncated form transcribed from exon 13. This was validated by analyzing CCLE cell line data, public CAGE data, and RT-PCR in primary cultured melanoma cell lines. Based on ESRP1 expression, we divided TCGA melanoma cases into ESRP1 low, truncated, and full-length groups. ESRP1-truncated tumors comprise approximately two-thirds of melanoma samples and reside in an apparent transitional state between epithelial and mesenchymal phenotypes. ESRP1 full-length tumors express epithelial markers and constitute about five percent of melanoma samples. In contrast, ESRP1-low tumors express mesenchymal markers and are high in immune cytolytic activity as well as PD-L2 and CTLA-4 expression. Those tumors are associated with better patient survival. Results from our study suggest a path toward the use of ESRP1 and other EMT markers as informative biomarkers for immunotherapy.
