AI's Role in Transforming Market Access

Exploring the Tension Between Promise and Skepticism

How can we leverage technology to improve patient outcomes in healthcare? The integration of artificial intelligence (AI) in market access presents both opportunities and challenges. This article delves into the critical impact AI can have on various stages of drug development, particularly in enhancing patient access while addressing growing skepticism regarding its effectiveness and reliability. We will examine three pivotal areas:

• The role of AI in clinical trial development and patient recruitment.
• How AI can streamline evidence generation and synthesis.
• The importance of validation and data protection in implementing AI solutions.

OPTIMIZING CLINICAL TRIAL DESIGN

One recurrent concern expressed by clients is the perceived lack of early involvement by market access teams in the design phase of clinical trials. To ensure endpoints align with the expectations of both regulatory and reimbursement entities, it is essential to integrate insights from market access from the outset. Currently, the most effective method for obtaining feedback on trial designs is through the early scientific advice (ESA) process, which is often cumbersome and requires initiation months prior to finalizing the trial protocol. This lengthy process can deter organizations, especially when they face multiple payers with sometimes conflicting demands.

• Machine learning models (MLMs) can analyze historical data to predict the acceptance of trial designs by payers in a matter of minutes.
• AI identifies relevant analogues to assess trial designs, though the accuracy may not be flawless, as no analogue will perfectly match the new product.
• Limited applicability for Joint Clinical Assessment (JCA) in the EU, which will start in phases from January 2025, noted for its complexity.

AI can also play a vital role in enhancing patient recruitment for clinical trials:

• Utilizes clinical trial matching systems to connect eligible patients with suitable trials.
• Analyzes electronic health records (EHRs) to model different trial designs and predict survival rates, optimizing patient selection criteria.

Moreover, AI tools can address concerns regarding high patient drop-out rates observed in trials, particularly those demanding extensive data collection:

• Predicts potential patient drop-out likelihood, enabling targeted educational outreach to encourage sustained participation.
• However, the use of predictive tools may pose ethical dilemmas by potentially narrowing recruitment to individuals less likely to drop out, risking trial diversity.

ACCELERATING EVIDENCE GENERATION

A significant barrier to utilizing real-world evidence more extensively rests on the need for meticulous manual curation of electronic health records (EHRs) and other patient data sources. This labor-intensive process is complicated by the inconsistent quality of data across various sources. Nonetheless, natural-language processing (NLP) tools can efficiently extract relevant EHR data with high accuracy rates, up to 96%, for various patient characteristics:

• EHR data extraction effectiveness is comparable to manual methods, although visual data extraction remains a challenge for NLP tools.
• To maximize accuracy, these tools need to be customized to local data variations due to differences in healthcare systems across regions.

An exciting advancement in this realm involves generating synthetic patient data using AI-based generative models, especially beneficial for rare diseases where recruitment poses challenges:

• Utilizes historical patient data to create digital replicas, or "digital twins," for trial participants.
• Predicts disease progression and treatment outcomes by comparing real participants with their digital counterparts.

STREAMLINING EVIDENCE SYNTHESIS

The process of synthesizing evidence has become a prime candidate for AI-driven automation, primarily due to its repetitive tasks. NLP-enhanced decision support systems are already operational in identifying key terms during abstract screenings or categorizing studies by design. Tools like Cochrane’s validated identification systems showcase this innovation:

• Supervised machine learning (ML) approaches can enhance automation in targeted literature reviews.
• However, these techniques still experience a slight reduction in accuracy compared to manual reviews, specifically a 5% drop in recall.

OPTIMIZING DOSSIER SUBMISSION PROCESSES

A clear and immediate application of AI within market access is the automation of template population for reimbursement submissions based on a reference, such as a global value dossier. Although reimbursement submissions extend beyond mere procedural tasks, AI can contribute significantly to strategic planning:

• Utilizes advanced data mining techniques to extract insights from past industry experiences.
• Supports strategy development by analyzing changes in policy and processes impacting reimbursement submissions.

REFINING ECONOMIC MODELING

The capabilities of large language models (LLMs) have made economic modeling another promising area for AI application. Recent studies demonstrate the ability of tools like GPT to accurately replicate economic models, achieving consistency with published incremental cost-effectiveness ratios within 1%:

• While minimal human intervention is necessary, minor adjustments are sometimes needed to streamline the model design.
• This suggests a significant opportunity for AI to aid in economic modeling responsibilities traditionally undertaken by human analysts.

REVOLUTIONIZING PRICING STRATEGIES

With the vast amount of available data to inform pricing strategies, it is evident that intricate pricing frameworks are increasingly in demand. The effective integration of data from various sources (e.g., clinical trials, patient outcomes, utilization data) is where machine learning algorithms excel:

• These algorithms rapidly adjust pricing strategies in response to changes in drug exclusivity, regulatory guidelines, or patent expirations.

LOOKING FORWARD

Two prevalent challenges associated with AI tools are replicability and transparency, necessitating thorough validation prior to their application in reimbursement submissions. This validation represents a key barrier to widespread AI adoption within market access, reflecting the need for health technology assessment (HTA) bodies to cultivate greater trust in AI methodologies. While AI possesses substantial potential to transform market access, a careful balance must be struck between leveraging its capabilities and ensuring rigorous expert validation and robust data protection, thereby achieving the primary objective of delivering timely and affordable healthcare products and services to patients.
