- Abstract summary: Drug-drug interactions (DDIs) refer to processes triggered by the administration of two or more drugs leading to side effects beyond those observed when drugs are administered by themselves.
Due to the massive number of possible drug pairs, it is nearly impossible to experimentally test all combinations and discover previously unobserved side effects.
We propose a Siamese self-attention multi-modal neural network for DDI prediction that integrates multiple drug similarity measures.

- Abstract: Background: Drug-drug interactions (DDIs) refer to processes triggered by the
administration of two or more drugs leading to side effects beyond those
observed when drugs are administered by themselves. Due to the massive number
of possible drug pairs, it is nearly impossible to experimentally test all
combinations and discover previously unobserved side effects. Therefore,
machine learning based methods are being used to address this issue.
Methods: We propose a Siamese self-attention multi-modal neural network for
DDI prediction that integrates multiple drug similarity measures that have been
derived from a comparison of drug characteristics including drug targets,
pathways and gene expression profiles.
Results: Our proposed DDI prediction model provides multiple advantages: 1)
It is trained end-to-end, overcoming limitations of models composed of multiple
separate steps, 2) it offers model explainability via an Attention mechanism
for identifying salient input features and 3) it achieves similar or better
prediction performance (AUPR scores ranging from 0.77 to 0.92) compared to
state-of-the-art DDI models when tested on various benchmark datasets. Novel
DDI predictions are further validated using independent data resources.
Conclusions: We find that a Siamese multi-modal neural network is able to
accurately predict DDIs and that an Attention mechanism, typically used in the
Natural Language Processing domain, can be beneficially applied to aid in DDI
model explainability.

Drug-Target Affinity (DTA) is of vital importance in early-stage drug discovery.
wet experiments remain the most reliable method, but they are time-consuming and resource-intensive.
Existing methods have primarily focused on developing techniques based on the available DTA data, without adequately addressing the data scarcity issue.
