panobinostat and Cardiotoxicity

Multiple myeloma accounts for over 10-15% of haematological malignancies. Continued molecular advances have resulted in the development of new drugs for treatment of multiple myeloma. Four drugs were approved by the Food and Drug Administration (FDA) in 2015, but their safety is not well defined. The aim of this study is to delineate the cardiovascular adverse events of these drugs.. We reviewed the adverse cardiac events of newly approved FDA drugs since 2015 using the US FDA Adverse Events Reporting System (FAERS) database. We calculated the reporting odds ratio (ROR) with 95% confidence interval (CIs) for the drugs that have the highest incidence of cardiovascular adverse events.. Among the medications that have approved for multiple myeloma between 2015 and 2020, 4 novel drugs showed the highest incidence of cardiotoxicity. ROR (95% CI) for atrial fibrillation due to elotuzumab, ixazomib, daratumumab and panobinostat compared to other FAERS drugs was 5.8 (4.4-7.7), 1.9 (1.5-2.3), 4.8 (4.2-5.6) and 5.7 (4.1-8.1), respectively. The ROR (95% CI) for cardiac failure was 8.2 (6.4-10.5), 4.7 (4.1-5.4), 5.8 (4.9-6.7) and 5.6 (3.8-8.1) and ROR (95% CI) for coronary disease was 2.7 (1.9-3.9), 2.7 (2.3-3.2), 2.3 (1.9-2.8) and 4.6 (3.2-6.6) due to elotuzumab, ixazomib, daratumumab and panobinostat compared to all other drugs in FAERS.. Our results demonstrated that certain newly approved antimyeloma therapies are significantly associated with previously unknown cardiotoxicity. These results warrant further studies and highlight the importance of considering the cardiac history of patients with multiple myeloma when utilizing these novel agents.

In the pharmaceutical industry risk assessments of chronic cardiac safety liabilities are mostly performed during late stages of preclinical drug development using in vivo animal models. Here, we explored the potential of human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs) to detect chronic cardiac risks such as drug-induced cardiomyocyte toxicity.. Video microscopy-based motion field imaging was applied to evaluate the chronic effect (over 72 h) of cardiotoxic drugs on the contractile motion of hiPS-CMs. In parallel, the release of cardiac troponin I (cTnI), heart fatty acid binding protein (FABP3) and N-terminal pro-brain natriuretic peptide (NT-proBNP) was analysed from cell medium, and transcriptional profiling of hiPS-CMs was done at the end of the experiment.. Different cardiotoxic drugs altered the contractile motion properties of hiPS-CMs together with increasing the release of cardiac biomarkers. FABP3 and cTnI were shown to be potential surrogates to predict cardiotoxicity in hiPS-CMs, whereas NT-proBNP seemed to be a less valuable biomarker. Furthermore, drug-induced cardiotoxicity produced by chronic exposure of hiPS-CMs to arsenic trioxide, doxorubicin or panobinostat was associated with different profiles of changes in contractile parameters, biomarker release and transcriptional expression.. We have shown that a parallel assessment of motion field imaging-derived contractile properties, release of biomarkers and transcriptional changes can detect diverse mechanisms of chronic drug-induced cardiac liabilities in hiPS-CMs. Hence, hiPS-CMs could potentially improve and accelerate cardiovascular de-risking of compounds at earlier stages of drug discovery..
