Drug effectiveness prediction software

Solution

Achievion leveraged sophisticated data analytics and machine learning models across multiple use cases, from oncology and vaccine safety to drug allergy risk assessment. Each of these areas required tailored approaches and predictive models to address unique healthcare challenges.

1. Machine Learning Models and Techniques

We employed a variety of machine learning models, including LASSO logistic regression, Gradient-Boosting Machines (GBM), Random Forests (RF), Naive Bayes, and Neural Networks, to maximize predictive accuracy and insights. By selecting models suited to each project’s unique data characteristics, the team achieved precise predictions and valuable insights that were directly applicable to real-world clinical decision-making.

2. Data Integration and Preparation

For each project, Achievion performed extensive data preparation and integration to ensure comprehensive analyses:

• Oncology: Data was drawn from observational, retrospective studies in new-user cohort datasets. By focusing on NSCLC patients with uncommon genetic mutations, we identified high-risk profiles for non-response to ALK inhibitor treatments.
• Vaccine Safety: Extensive information was extracted from Electronic Health Records (EHRs), doctor’s visits, urgent care records, and hospital admissions. The data preparation process included detailed aggregation of variables like age and prior health status to assess risk probabilities for vaccine-related side effects.
• Drug Allergy: The allergy risk analysis covered data on 276,665 epilepsy patients, segmented into multiple datasets. This allowed for more granular analysis and a deeper understanding of potential allergic reactions, particularly with specific epilepsy drug components.

3. Advanced Analytics Tools and Techniques

The projects utilized a range of analytics tools, including SQL, R, Python, RStudio, and Atlas. These tools supported complex statistical modeling, predictive analysis, and the ability to handle large healthcare datasets. For instance, SQL and Python enabled data cleaning and transformation, while R and RStudio facilitated model tuning and result visualization, enhancing the interpretability of predictions for clinical stakeholders.

4. Custom Algorithm Development

For each project, our team developed custom algorithms to deliver precise predictions and actionable insights:

• Cancer Treatment Predictions: The algorithms predicted the likelihood of treatment non-response, empowering clinicians to make evidence-based decisions and consider alternative treatments or clinical trials.
• Vaccine Side Effect Risk Assessment: The solution computed the probability of fever and seizure post-vaccination, offering vital information to caregivers and regulators on vaccine safety for children.
• Drug Allergy Prediction: The algorithms analyzed allergic reaction risks to epilepsy drugs, supporting clinicians in optimizing prescribing decisions.
