HOW AI DRUG DISCOVERY WORKS

The Complete 5-Stage Pipeline

STAGE 1: Target Identification & Validation

Traditional: 2-4 years, 10-15% success rate, hypothesis-driven

AI Revolution:

1. Multi-Omic Integration:

• Analyzes genomics (GWAS, whole genome), transcriptomics (single-cell RNA-seq), proteomics, metabolomics, phenomics
• Deep neural networks identify correlations invisible to humans

Insilico TNIK Discovery:

• PandaOmics analyzed 17,382 samples (54 tissues), IPF patient biopsies, single-cell signatures
• Identified TNIK despite limited prior literature linking to IPF
• Traditional approaches would miss this buried in multi-dimensional data

2. Causal Inference:

• Methods: Mendelian randomization, CRISPR perturbation experiments, Bayesian networks
• Distinguishes causation from correlation
• Validates targets experimentally but AI prioritizes candidates

3. Druggability Assessment:

• AlphaFold 3 protein structure prediction identifies binding pockets
• Estimates if small molecules can bind with drug-like properties
• Predicts tolerability and clinical translatability

AI Tools:

• PandaOmics (Insilico): Deep learning multi-omics, end-to-end
• Phenomic AI (Recursion): Cellular imaging + ML, unbiased biology
• BENEVOLENT (BenevolentAI): Knowledge graphs + NLP
• EVA (LabGenius): ML + protein engineering
• gRED (Genentech/Roche): Proprietary internal AI

Success: 25-35% target progression (AI) vs 10-15% (traditional) Timeline: 6-12 months vs 2-4 years

STAGE 2: Hit Identification & Lead Generation

Challenge: 10^60 possible drug-like molecules (more than atoms in universe) Traditional HTS: 1-2 million compounds tested AI: Explores billions of virtual compounds

Generative Chemistry – Core Innovation:

Rather than screening existing molecules, AI generates novel molecules designed for target

Approaches:

A. Graph Neural Networks (GNNs):

• Molecules as graphs: atoms=nodes, bonds=edges
• Message-passing learns molecular representations
• Predicts properties before synthesis
• Tools: Chemprop (MIT), Atomwise, Exscientia

B. Variational Autoencoders (VAEs):

• Encoder compresses molecules → latent space
• Decoder generates molecules from latent representations
• Interpolation produces novel similar molecules
• Challenge: Sometimes chemically invalid
• Insilico Chemistry42 uses VAE + reinforcement learning

C. Generative Adversarial Networks (GANs):

• Generator creates candidates, discriminator evaluates “drug-likeness”
• Advantage: Diverse structures
• Disadvantage: Training instability

D. Molecular Transformers (State-of-Art):

• Treat molecules as “sentences” in SMILES notation
• Self-attention captures long-range interactions
• Pre-trained on millions of molecules, fine-tuned for properties
• Insilico platform: Pre-trained on 1.7B molecules, fine-tuned on TNIK data

Multi-Objective Optimization:

Simultaneous optimization:

• Efficacy: Binding affinity <100nM, selectivity >100-fold, cellular potency
• Safety: No hERG binding, no CYP inhibition, no reactive metabolites
• PK: Bioavailability >30%, half-life 6-24h, BBB penetration (if CNS)
• Drug-likeness: Lipinski Rule of 5, synthesizability <10 steps, IP position

AI Solution: Multi-objective reinforcement learning

• Reward function combines all objectives
• AI proposes molecules, receives reward based on predictions
• Learns to maximize cumulative reward
• Thousands of virtual molecules evaluated per minute

Insilico rentosertib:

• Generated ~78,000 molecules
• Filtered to 60 for synthesis
• 10 compounds <100nM TNIK IC50
• Optimized for solubility, ADME, CYP
• Final: 30nM potency, excellent PK, 6-step synthesis
• 18 months target-to-preclinical vs 3-5 years traditional

Virtual Screening:

Atomwise AtomNet screens billions:

• 3D protein structure (experimental or AlphaFold)
• Docking algorithms predict binding poses
• Deep learning scores affinity
• Top candidates synthesized

Comparison:

• Traditional HTS: 1-2M compounds, $1-2M, 3-6 months, 0.01-0.1% hit rate
• AI virtual: 1B+ compounds, $50-100K, 2-4 weeks, 5-15% hit rate

STAGE 3: Lead Optimization & ADMET Prediction

Challenge: Initial hits rarely become drugs

Optimization improves potency (100nM → 1-10nM), selectivity (10-fold → 100-1000-fold), PK, safety

AI-Accelerated DMTA Cycles:

Traditional DMTA: 5-9 weeks/cycle, 10-15 cycles = 12-24 months

• Design (1-2 weeks) → Synthesis (2-4 weeks) → Test (1-2 weeks) → Analyze (1 week)

AI DMTA: 2-3 weeks/cycle, 8-12 cycles = 4-8 months

• AI proposes 50-100 ranked analogs (1-2 days)
• Automated synthesis (1 week)
• High-throughput testing (3-5 days)
• ML model updated (1 day)

Key: Active learning

• ML trained on initial data
• Predicts virtual analog properties
• Selects most informative molecules (exploration-exploitation)
• Continuously improves

ADMET Prediction (2026 state-of-art):

Property	Accuracy	Model	Training Data
Solubility	R²=0.75-0.85	GNN, RF	10K+
LogP	R²=0.80-0.90	GNN	50K+
Plasma binding	R²=0.70-0.80	DNN	5K+
hERG	AUC=0.85-0.92	GNN/DNN	8K+
CYP inhibition	AUC=0.80-0.88	Multitask DNN	15K+
Hepatotoxicity	AUC=0.75-0.85	GNN	2K+
BBB penetration	Acc=85-92%	Classification	3K+
Bioavailability	R²=0.60-0.75	Ensemble	1K+ (limited)

Limitations: Lower accuracy than binding (less data), complex biology not fully captured, confidence varies

Best practice: Use AI for prioritization, validate experimentally before in vivo

Retrosynthesis AI:

Problem: AI designs molecules impossible to synthesize

Solution: Retrosynthesis planning

• Start with target molecule
• AI suggests disconnections into simpler precursors
• Recursively decompose to commercial starting materials
• Assess complexity (steps, yield, cost)

Tools: IBM RXN, Iktos Spaya, AiZynthFinder

Insilico Chemistry42: Integrates synthesizability during generation, >90% proposed molecules synthesizable <10 steps

STAGE 4: Preclinical Validation (Hybrid AI-Experimental)

AI Cannot Replace Wet Lab (Yet)

Experimental validation essential:

• In vitro: Biochemical assays, cellular assays, selectivity profiling
• In vivo: Animal efficacy models, PK, toxicology

AI’s Role:

1. Experiment Design: ML predicts optimal dosing, adaptive designs, reducing animals (3Rs)
2. Data Analysis: Computer vision pathology (Recursion), multi-modal integration
3. Human Translatability: PBPK modeling, predicting human PK from animals

Digital Twins & In Silico Models:

Emerging: Virtual physiological models replacing some animal studies

FDA Precedent: UVA/Padova Diabetes Simulator accepted for CGM approval (virtual patients)

Applications:

• Quantitative Systems Pharmacology (QSP): Disease biology models
• Virtual organs: Liver, heart, kidney drug effects
• PK/PD modeling: Dose-response predictions

Limitation: Regulatory acceptance limited; full animal replacement not approved for small molecules yet

2026 Outlook: FDA April 2025 NAM roadmap signals openness to validated in silico models

FDA REGULATORY FRAMEWORK FOR AI DRUG DISCOVERY

Navigating the New Regulatory Landscape

The regulatory acceptance of AI-discovered drugs represents one of the pharmaceutical industry’s most critical uncertainties. On January 6, 2025, the U.S. Food and Drug Administration published draft guidance titled “Considerations for the Use of Artificial Intelligence to Support Regulatory Decision Making for Drug and Biological Products” – the first comprehensive regulatory framework addressing AI throughout the drug development lifecycle. This section provides a complete analysis of FDA’s approach, submission requirements, and strategic implications for AI drug discovery.

📋 January 2025 FDA Draft Guidance: Complete Analysis

Background & Development Process

The FDA’s AI guidance emerged from extensive stakeholder engagement:

December 2022: Duke Margolis Institute expert workshop convened by FDA CDER May 2023: FDA published discussion paper on AI/ML use in drug development (800+ public comments received) 2016-2023: FDA reviewed 500+ submissions containing AI components August 2024: Hybrid public workshop on guiding principles for responsible AI use January 6, 2025: Draft guidance published April 2025: Original comment deadline (extended to Q1 2026) Q2 2026: Final guidance expected

Scope & Applicability

What the guidance covers:

• AI models used in drug discovery (target identification, molecule design)
• AI supporting nonclinical studies (ADMET prediction, toxicology)
• AI in clinical trial design (patient selection, endpoint prediction)
• AI for manufacturing and quality control

What is EXCLUDED:

• AI used purely for internal R&D without regulatory submission
• AI that doesn’t impact patient safety, drug quality, or clinical trial reliability
• Software as a Medical Device (SaMD) – covered by separate guidance
• AI for administrative purposes (scheduling, resource allocation)

Critical distinction: If AI is used to discover a drug but traditional validation methods confirm safety/efficacy, extensive AI documentation may not be required. The guidance focuses on AI that directly supports regulatory decision-making.

🎯 Risk-Based Framework: Context of Use

Core Principle

FDA’s approach centers on “context of use” – how the AI model is deployed and what decisions it influences.

Three Risk Tiers:

HIGH RISK: AI directly determines patient safety, drug quality, or pivotal clinical trial outcomes

• Examples: AI predicting clinical endpoints without validation, AI controlling manufacturing critical quality attributes
• Requirements: Extensive documentation, prospective validation, continuous monitoring

MEDIUM RISK: AI informs decisions but human oversight/validation present

• Examples: AI-generated molecules tested experimentally, AI patient stratification with biomarker confirmation
• Requirements: Model credibility assessment, validation data, bias mitigation

LOW RISK: AI supports exploratory or hypothesis-generating activities

• Examples: AI target identification validated through orthogonal methods, AI literature mining
• Requirements: Minimal documentation, focus on output validation

Context of Use Examples from Guidance

Example 1: Target Identification

• Scenario: AI analyzes multi-omics data to identify disease target
• Context: Target validated through traditional biochemical and genetic experiments
• Risk Level: LOW (AI hypothesis-generating, validation independent)
• Documentation: Describe AI platform, acknowledge use, provide validation data

Example 2: Lead Optimization

• Scenario: AI generates molecule designs optimized for target and ADMET
• Context: All molecules synthesized and tested experimentally before IND
• Risk Level: MEDIUM (AI informs but doesn’t replace experimental validation)
• Documentation: Model architecture, training data description, optimization objectives, validation against experimental results

Example 3: Clinical Trial Endpoint Prediction

• Scenario: AI predicts long-term outcome from early biomarkers to support accelerated approval
• Context: Prediction is basis for regulatory decision without long-term follow-up
• Risk Level: HIGH (directly impacts approval decision)
• Documentation: Complete model transparency, prospective validation, post-market monitoring plan

Example 4: Synthetic Control Arm

• Scenario: AI generates virtual patients as control group in single-arm trial
• Context: Synthetic controls partially replace real placebo patients
• Risk Level: HIGH (affects trial interpretation and approval)
• Documentation: Algorithm validation, similarity to target population, sensitivity analyses, FDA pre-submission meeting recommended

📊 AI Model Credibility Assessment

Five Credibility Domains

FDA requires applicants to establish AI model credibility across five domains:

1. Data Quality & Governance

Training Data Requirements:

• Source and provenance (commercial databases, proprietary data, literature)
• Size and diversity (number of compounds, patients, experimental conditions)
• Representativeness (does training data reflect intended use population?)
• Data cleaning and preprocessing steps
• Handling of missing data, outliers, errors

Data Governance:

• Version control (training data versioning)
• Access controls (who can modify training data?)
• Quality assurance procedures
• Documentation of data transformations

Example – Insilico Medicine’s rentosertib:

• Training data: 1.7 billion molecules from public databases (PubChem, ChEMBL)
• Fibrosis-specific data: IPF patient samples, animal model data, protein structures
• Preprocessing: Standardized SMILES notation, duplicate removal, invalid structure filtering
• Versioning: Dataset version 2.3 used for rentosertib generation (documented)

2. Model Architecture & Development

Required Documentation:

• Model type (transformer, GNN, random forest, ensemble)
• Architecture details (layers, parameters, activation functions)
• Hyperparameter selection (how were they optimized?)
• Training procedure (optimization algorithm, learning rate, epochs)
• Overfitting prevention (cross-validation, regularization, early stopping)

Interpretability Considerations:

• For HIGH-risk contexts: Explainable AI methods required (attention maps, SHAP values, feature importance)
• For MEDIUM-risk: Some interpretability helpful but not mandatory
• For LOW-risk: Black-box models acceptable if validated

Example – Relay Therapeutics RLY-2608:

• Model: Molecular dynamics simulations + machine learning
• Architecture: Physics-based protein motion modeling (proprietary)
• Validation: Predicted binding poses confirmed by X-ray crystallography
• Interpretability: Structural visualization of predicted protein-drug interactions

3. Model Performance & Validation

Validation Types:

Internal Validation (minimum requirement):

• Holdout test set (20-30% of data never seen during training)
• Cross-validation (k-fold, leave-one-out for small datasets)
• Performance metrics appropriate to task (R², AUC, accuracy, precision/recall)

External Validation (preferred for HIGH-risk):

• Independent dataset from different source than training
• Prospective validation (model frozen, new data collected)
• Head-to-head comparison with existing methods

Temporal Validation (for continuously learning models):

• Performance on data collected after model training
• Demonstrates generalization over time

Performance Metrics:

• Accuracy alone insufficient (must report precision, recall, F1, calibration)
• Confidence intervals or uncertainty quantification
• Performance stratified by subgroups (age, sex, race if applicable)

Example – BenevolentAI Knowledge Graph:

• Internal validation: 80% training, 20% test split
• External validation: Literature published after model training cutoff
• Metrics: Precision@10 for target-disease predictions, clinical validation rate
• Subgroup analysis: Performance consistent across therapeutic areas

4. Bias Mitigation & Fairness

Sources of Bias:

Data Bias:

• Training data skewed toward certain demographics (mostly European ancestry genomics)
• Publication bias (positive results over-represented)
• Survivorship bias (only successful drugs in training data)

Algorithm Bias:

• Model learns to perpetuate historical biases
• Proxy variables (using correlated features as shortcuts)
• Feedback loops (model predictions influence future data collection)

Mitigation Strategies:

Diverse Training Data:

• Include underrepresented populations (race, ethnicity, age, sex)
• Rare diseases and orphan indications
• Failed drug candidates (not just approved drugs)

Fairness Testing:

• Model performance stratified by demographic subgroups
• Identify differential error rates
• Algorithmic fairness metrics (equalized odds, demographic parity)

Debiasing Techniques:

• Reweighting training samples
• Adversarial debiasing
• Post-processing calibration

FDA Expectation: Acknowledge limitations, document mitigation efforts, monitor for disparate impact

Example – Recursion Phenomics:

• Data diversity: Cell lines from diverse genetic backgrounds
• Disease coverage: 100+ rare diseases (not just common conditions)
• Performance monitoring: Stratified by disease rarity, patient demographics
• Transparency: Publicly disclose limitations in model applicability

5. Lifecycle Management & Continuous Monitoring

For Static Models (not updated post-deployment):

• Periodic performance checks on new data
• Drift detection (is incoming data similar to training distribution?)
• Versioning and archiving (which model version used for which submission?)

For Continuously Learning Models (adapt over time):

• Change management procedures (when/how model updated)
• Revalidation triggers (performance degradation thresholds)
• FDA notification requirements for material changes

Post-Market Surveillance:

• For HIGH-risk AI: FDA may require post-approval monitoring
• Track model performance in real-world use
• Report unexpected outcomes or model failures

Example – Schrödinger FEP+ Platform:

• Static model: Version locked for each IND submission
• Validation: Each new drug candidate’s predicted vs. observed binding affinity tracked
• Drift monitoring: If experimental results deviate >20% from predictions, model reassessed
• FDA communication: Major platform updates disclosed in regulatory correspondence

📝 Submission Requirements & Documentation

Status: ICH initiating AI guideline development (2025-2027 timeline)

Goal: Harmonized requirements across US, EU, Japan for AI in drug development

Challenges: Balancing innovation encouragement with safety assurance; different regional AI maturity levels

🔐 Intellectual Property Considerations Under FDA Transparency

The Tension

FDA transparency requirements potentially conflict with trade secret protection:

• AI model architecture disclosure
• Training data descriptions
• Algorithm details

Risk: Competitors could reverse-engineer proprietary AI platforms

Mitigation Strategies

1. Patent Before Disclose

• File patents on AI models/algorithms before IND submission
• Patents on AI-discovered molecules
• Timing: File 12-18 months before IND if possible

2. Selective Disclosure

• Disclose what FDA requires (architecture, validation) but not implementation details
• Provide performance metrics without revealing proprietary algorithms
• Use confidentiality procedures for sensitive information

3. Trade Secret Protection

• For LOW-risk AI (exploratory use), minimal disclosure required
• Keep proprietary details as trade secrets if not required for regulatory decision

4. Hybrid Approach

• Patent core innovations (novel architectures, unique training approaches)
• Trade secret for datasets, hyperparameters, implementation details

Example – Schrödinger FEP+:

• Patents: Physics-based simulation methods (granted)
• Trade secrets: Specific parameter sets, proprietary force fields
• FDA disclosure: Validation data, performance metrics (no proprietary algorithms shared)

📅 April 2025 Non-Animal Methods (NAM) Roadmap

FDA’s Vision for AI and In Silico Models

In April 2025, FDA released roadmap for reducing animal testing, highlighting AI role:

Key AI Applications:

1. In Silico Toxicology:

• AI models trained on large toxicology databases
• Predict organ toxicity, genotoxicity, carcinogenicity
• Goal: Replace some animal studies for hazard identification

2. Physiologically-Based PK (PBPK) Models:

• AI-enhanced PBPK predicting human PK from in vitro data
• Reduce animal PK studies

3. Quantitative Structure-Activity Relationships (QSAR):

• AI-powered QSAR for safety assessments
• Acceptance expanding beyond well-defined chemical classes

4. In Silico Clinical Trials (ISCT):

• Computational patient models simulate trial outcomes
• Validated for device testing, expanding to drugs

Current Status:

• AI toxicology models: Accepted for weight-of-evidence, not sole basis
• PBPK: Accepted with experimental validation
• QSAR: Case-by-case acceptance
• ISCT: Pilot programs, not yet routine

2026-2030 Outlook: Gradual expansion as models validated

FDA Precedent: UVA/Padova Type 1 Diabetes Simulator accepted for CGM approval – demonstration that validated in silico models can support regulatory decisions

💡 Strategic Recommendations for AI Drug Developers

Best Practices

1. Document Everything from Day One

• Version control for models, datasets, code
• Audit trails for model changes
• Rationale for design choices

2. Validate Rigorously

• External validation datasets
• Prospective validation when possible
• Compare AI predictions to experimental results throughout development

3. Engage FDA Early

• Pre-IND meetings for HIGH-risk AI
• Type C meetings for methodology questions
• Build relationships with FDA reviewers

4. Plan for Interpretability

• Even if not required, explainability helpful for FDA discussions
• Case studies showing AI reasoning
• Comparison with expert human decisions

5. Address Bias Proactively

• Diverse training data from start
• Fairness metrics in validation
• Transparency about limitations

6. Protect IP Strategically

• Patent before IND if possible
• Selective disclosure (what’s required vs. proprietary)
• Confidentiality agreements for sensitive data

Red Flags to Avoid

1. Black Box AI for HIGH-risk Decisions

• If AI predicts clinical endpoint without validation → HIGH scrutiny
• Solution: Provide interpretability evidence or reduce risk level via human oversight

2. Insufficient Validation

• Training set performance only (no test set) → Inadequate
• Solution: Proper train/test split, external validation

3. Data Quality Issues

• Unverified data sources, missing data not addressed → Credibility questioned
• Solution: Rigorous data governance, document cleaning

4. Overfitting Indicators

• Perfect training performance, poor test performance → Model not trustworthy
• Solution: Cross-validation, regularization, reasonable performance expectations

5. Undisclosed Model Changes

• Updating model during development without documentation → Regulatory concern
• Solution: Version control, change management, FDA notification

FAQ:

BASICS

Q1: What is AI drug discovery?

Using artificial intelligence/machine learning to accelerate pharmaceutical R&D: target identification, molecule design, optimization, clinical trial design. Reduces timelines 30-40%, costs 25-40%, improves success rates.

Q2: How does it differ from traditional drug discovery?

Traditional relies on high-throughput screening (testing millions of existing molecules), hypothesis-driven target selection, manual medicinal chemistry. AI generates novel molecules computationally, explores billions of virtual compounds, predicts properties before synthesis.

Q3: Which companies lead the field?

Tier 1 (clinical validation): Insilico Medicine, Relay Therapeutics, Schrödinger. Tier 2 (strong tech/partnerships): Exscientia-Recursion, Atomwise, BenevolentAI. See Section 6 for full profiles.

Q4: What are the costs to implement AI drug discovery?

$25K-$100K per use case (amortized). Initial setup $500K-$2M, ongoing $2-7M/year for mid-sized pharma. Economies of scale for large portfolios.

Q5: How long until AI-discovered drugs are commonplace?

Already happening: 200+ in clinical development, first approval anticipated 2026-2027. By 2030, 30-40% of new drugs will use AI in discovery.

TECHNICAL

Q6: How accurate are AI predictions?

Binding affinity: R²=0.7-0.85 | ADMET properties: R²=0.6-0.9 (varies by property) | Not perfect but dramatically better than random. Experimental validation still essential.

Q7: What AI models are used?

Transformers (molecule generation), Graph Neural Networks (property prediction), VAEs/GANs (generative), reinforcement learning (optimization), molecular dynamics + ML (Schrödinger). See Section 3 for details.

Q8: Can AI replace wet lab experiments?

No. AI accelerates discovery and prioritizes experiments, but cannot replace experimental validation. Hybrid approach: AI generates hypotheses, wet lab validates.

Q9: How is training data obtained?

Public databases (PubChem, ChEMBL, Protein Data Bank), proprietary pharma data, literature mining, experimental data generation. Quality > quantity.

Q10: What about novel targets with no training data?

Transfer learning: pre-train on related targets, fine-tune on limited data. Generative models can extrapolate. AlphaFold enables structure-based design without experimental structures.
