摘要:

复杂或共存的疾病通常使用药物组合治疗,这可能导致更高的不良副作用风险。多药副作用的检测通常在IV期临床试验中进行,但当药物投放市场时,仍然有很多未被发现。此类事故已经影响了越来越多的人群(目前在美国为15%),因此能够尽早预测潜在的副作用是非常重要的。可能的药物-药物相互作用(DDI)的系统组合筛选具有挑战性且昂贵。然而,最近的显着增加,从药物研究和开发工作的数据可用性提供了一个新的范例,恢复相关的见解DDI预测。因此,最近的几种方法专注于管理大量DDI数据集(具有数百万个示例)并在其上训练机器学习模型。在这里,我们提出了一个神经网络架构,能够设置最先进的结果在这个任务上-使用的类型的副作用和药物的分子结构单独-通过利用共同注意机制。特别是,我们展示了在学习每种药物的表示时,早期从药物对中整合联合信息的重要性。

英文摘要:

Complex or co-existing diseases are commonly treated using drug combinations, which can lead to higher risk of adverse side effects. The detection of polypharmacy side effects is usually done in Phase IV clinical trials, but there are still plenty which remain undiscovered when the drugs are put on the market. Such accidents have been affecting an increasing proportion of the population (15% in the US now) and it is thus of high interest to be able to predict the potential side effects as early as possible. Systematic combinatorial screening of possible drug-drug interactions (DDI) is challenging and expensive. However, the recent significant increases in data availability from pharmaceutical research and development efforts offer a novel paradigm for recovering relevant insights for DDI prediction. Accordingly, several recent approaches focus on curating massive DDI datasets (with millions of examples) and training machine learning models on them. Here we propose a neural network architecture able to set state-of-the-art results on this task---using the type of the side-effect and the molecular structure of the drugs alone---by leveraging a co-attentional mechanism. In particular, we show the importance of integrating joint information from the drug pairs early on when learning each drug's representation.
