Abstract: Obesity substantially increases the risk of type 2 diabetes, cardiovascular disease, and other diseases, making it a leading preventable cause of death in developed countries. It has a strong genetic basis, with obesity-associated genetic variants preferentially acting in the brain. This includes the hypothalamic pro-opiomelanocortin (POMC) neurons that inhibit food intake and are stimulated by drugs that agonise glucagon-like 1 peptide receptor (GLP1R) including Semaglutide (Ozempic/Wegovy). We therefore hypothesised that drugs which selectively activate human POMC neurons would suppress appetite and promote weight loss, and that focusing on drugs already approved for use would facilitate rapid clinical translation. We therefore generated POMC neurons from human pluripotent stem cells (hPSCs) and identified enriched genes that were genetically associated with obesity and targeted by approved drugs. We found that human POMC neurons are enriched in GLP1R, reliably activated by Semaglutide, and their responses are further increased by co-administration of Ceritinib, an FDA-approved drug potently and selectively inhibiting anaplastic lymphoma kinase (ALK). Ceritinib reduced food intake and body weight in obese but not lean mice, and upregulated the expression of GLP1R in the mouse hypothalamus and hPSC-derived human hypothalamic neurons. These studies reveal a new potential therapeutic strategy for reducing food intake and body weight, and demonstrate the utility of hPSC-derived hypothalamic neurons for drug discovery.

This week, we'll be discussing research highlights in lung cancer presented at the ESMO Congress 2019, including the FLAURA trial of osimertinib in EGFR-mutated non–small cell lung cancer; the CheckMate 227 of nivolumab plus ipilimumab vs chemotherapy in non–small cell lung cancer with a PD-L1 expression of 1% or more; and the ASCEND-7 trial of ceritinib for ALK-positive non–small cell lung cancer that has spread to the brain.Coverage of stories discussed this week on ascopost.com:ESMO 2019: Overall Survival With Immunotherapy Doublet vs Chemotherapy in Advanced NSCLCESMO 2019: ASCEND-7: Ceritinib for Patients With ALK-Positive NSCLC Metastatic to the Brain
MUNICH— Anaplastic lymphoma kinase (ALK) inhibitors are as effective in “real world” clinical use for treating patients with non-small cell lung cancer (NSCLC) who test positive for ALK gene rearrangements as they are in clinical studies—even though randomized trials “cherry …Mohammad Jahanzeb AJ0

Dr Scagliotti speaks to ecancertv at ESMO 2016 about results from the confirmatory phase III trial ASCEND-5. He summarises these results, confirming the benefit of ceritinib for lung cancer patients with ALK rearrangements who had previously received crizotinib, and goes on to consider the impact of kinase inhibitor therapy.
Dr Scagliotti presents, at a press conference at ESMO 2016, results from the ASCEND-5 trial of ceritinib, a kinase inhibitor targeting ALK rearrangements, for patients with advanced non-small cell lung cancer who had relapsed following crizotinib therapy.
Dr Felip speaks with ecancer at ASCO 2017 about results from a phase II dose escalation study of ceritinib, an ALK inhibitor, administered with nivolumab to treat patients with ALK non small cell lung cancer. She outlines the toxicity associated with the trials, which resulted in many adverse events including severe incidence of rashes, which has led to the dosage being amended for future trials, and considers how the interplay between ALK inhibition and PD1 targeting may have resulted in this severe reaction.
COPENHAGEN—Longer progression free survival (PFS) was achieved in patients with ALK-rearranged non-small cell lung cancer (NSCLC) previously treated with crizotinib randomised to treatment with the second generation anaplastic lymphoma kinase (ALK) inhibitor ceritinib rather than chemotherapy in the phase 3 …161207-esmo-giorgio-scagliotti-ajo-production-master

Drs. Leora Horn, Ben Solomon, & Jack West review whether there are specific factors that should make one second generation ALK inhibitor more ideal than other competing options for a specific patient with an ALK rearrangement.
Drs. Ben Solomon, Leora Horn, & Jack West evaluate the evidence and consider whether there are clinically significant differences among the second generation ALK inhibitors that would lead to a reason to prefer one over another for a particular patient.
