Explainable Drug Sensitivity Prediction through Cancer Pathway Enrichment Scores
(PathDSP)

Short Description

This is a community model for drug response prediction curated as part of the IMPROVE project.

Description and Impact
Impact

Enables prediction of drug response with drug and cancer features. 

Hypothesis/Objective

Pan-drug, pan-cancer, single drug response prediction model.

Technical Elements
Uniqueness

PathDSP first converts the cancer and drug features into pathway-level enrichment scores using a network-based approach, then feeds those into a fully connected neural network (FNN) with four hidden layers.

Usability

A data scientist can train the provided untrained model on their own data or use the trained model to classify the provided test samples. The provided scripts use the IMPROVE Benchmark Dataset. 

Components

The model-related files are located in Model and Data Clearinghouse (MoDaC), and the source code is on GitHub.

Inputs
  • Cancer features: Gene Expression, Mutation, Copy Number Variation
  • Drug features: Drug Fingerprints, Drug Target
Results
Outputs

Predicted drug response values for a given sample and drug pair and metrics if ground truth is provided.
