Building Prescription Digital Therapeutics: A Product Playbook for Digital Health Leaders

Prescription digital therapeutics are reshaping how we treat medical conditions through software. Unlike wellness apps that track steps or offer meditation guidance, prescription digital therapeutics are clinically validated interventions, approved or cleared by regulatory bodies like the FDA, and prescribed by a licensed healthcare provider. They are developed to treat, manage, or prevent specific diseases, often targeting chronic or behavioral health conditions, using evidence-based protocols delivered through mobile apps, wearables, or digital platforms.

What makes prescription digital therapeutics different is their medical-grade intent. These solutions undergo rigorous testing for safety, efficacy, and regulatory compliance, often playing a complementary role alongside pharmaceuticals or behavioral therapies. In contrast, wellness apps focus on general lifestyle improvements and are not subjected to the same clinical or regulatory scrutiny.

As healthcare embraces digital transformation, PDTs represent a critical bridge between consumer-grade health tools and formal clinical interventions, access, adherence, and long-term outcomes.

➡️ Why Digital Health Products Are Evolving Toward Prescription Digital Therapeutics

The digital health landscape has matured rapidly over the past decade. What began as a wave of fitness trackers and wellness apps has evolved into a clinically oriented ecosystem, where software isn’t just assisting care—it’s becoming the care. Prescription digital therapeutics sit at the center of this shift, offering a regulated, evidence-backed path to managing medical conditions through digital means.

🔹 Trends Driving the Shift

Payer Interest in Evidence-Based Solutions

Payers are increasingly investing in solutions that demonstrate measurable outcomes. Unlike general wellness apps, PDTs are backed by clinical studies and real-world data, making them more viable for reimbursement under existing and emerging payer frameworks.

Rise of Digital Formularies

Pharmacy benefit managers (PBMs) and health systems are creating digital formularies—curated lists of approved digital therapeutics. This institutional recognition opens formal reimbursement pathways and solidifies PDTs as part of the broader healthcare toolkit.

Focus on Clinical Validation

Wellness products rarely move beyond user engagement metrics. PDTs, however, are validated through randomized controlled trials, behavioral outcome studies, and adherence metrics. This alignment with traditional medical expectations makes them more attractive to providers, insurers, and regulators.

🔹 The Strategic Advantage: Outcomes Over Engagement

For digital health companies, shifting from “apps that engage” to “apps that heal” presents a powerful differentiator. Building prescription digital therapeutics allows product teams to:

1. Enter less saturated, reimbursement-ready markets
2. Gain credibility with healthcare providers and payers
3. Drive long-term retention through prescribed, outcomes-based use

In other words, PDTs aren’t just apps—they’re interventions. And that distinction opens up entirely new business models rooted in clinical value and medical legitimacy.

🔹 Market Snapshot & Potential

1. The global PDT market is projected to reach $13+ billion by the end of this decade, fueled by demand in mental health, chronic disease, and neurobehavioral conditions.
2. Over 35 PDTs have already received FDA clearance, with major players like Pear Therapeutics, Akili Interactive, and Big Health leading.
3. Conditions like ADHD, substance use disorder, anxiety, and IBS are among the first adopters, showcasing PDTs’ versatility across care pathways.

As digital health companies look to scale sustainably and win payer trust, building prescription digital therapeutics is no longer optional—it’s a strategic imperative.

➡️ Understanding the Regulatory Path to Market

One of the defining features of prescription digital therapeutics is that they are regulated medical products, subject to oversight by the U.S. Food and Drug Administration (FDA) or equivalent authorities in other markets. Navigating this path is complex but essential for unlocking the credibility, reimbursement, and scalability that PDTs promise.

🔍 Where PDTs Fit Under SaMD Classification

Prescription digital therapeutics are a specific type of Software as a Medical Device (SaMD)—software intended to diagnose, treat, or manage a medical condition without being part of a hardware medical device.

The FDA classifies and reviews SaMD products using a risk-based framework. PDTs typically fall into Class II (moderate risk), requiring a clear demonstration of safety, efficacy, and intended use.

Depending on novelty and clinical risk, a PDT may go through:

1. 510(k) clearance (if a substantially equivalent device exists)
2. De Novo classification (for novel low-to-moderate risk products)
3. Pre-Market Approval (PMA) (for higher-risk innovations—rare for PDTs)

Understanding where your product fits early in development is key to choosing the right validation and submission strategy.

📌 Prescription Digital Therapeutics Examples (FDA-Cleared)

Here are three standout examples that have successfully navigated the regulatory process:

1. EndeavorRx – Cleared via De Novo, this pediatric ADHD treatment uses a mobile game to improve attention function.
2. reSET-O – A PDT for opioid use disorder, delivering cognitive behavioral therapy via a smartphone app, supported by clinical studies and CPT code alignment.
3. DaylightRx – Targets generalized anxiety disorder using CBT principles delivered through a mobile app, cleared through the 510(k) pathway.

These examples highlight the diversity of use cases and the growing maturity of the regulatory landscape for PDTs.

➡️ Common Challenges (and How to Navigate Them)

While the opportunity around prescription digital therapeutics is enormous, building and launching a successful PDT comes with unique challenges. Many product teams underestimate the shift from “software that supports care” to “software that is care”—until they hit regulatory, clinical, or go-to-market roadblocks.
Below are the most common pain points teams encounter and how to think about solving them.

🧪 Long Timelines for Evidence Generation

The challenge:

• PDTs require clinical validation, often through randomized controlled trials or large real-world studies. These processes can stretch timelines and strain early-stage teams.

How to navigate it:

1. Consider a modular approach to validation (pilot > feasibility > full RCT)
2. Use real-world data and digital endpoints where appropriate
3. Partner with clinical research organizations (CROs) experienced in SaMD

⚖️ Regulatory Ambiguity for Digital Products

The challenge:

• Unlike drugs or devices with decades of precedent, PDTs live in a still-maturing regulatory space. Teams often struggle to map their innovation to the right FDA pathway or anticipate evolving compliance needs.

How to navigate it:

1. Engage a regulatory advisor early—don’t DIY the De Novo
2. Use the FDA’s SaMD guidance and existing cleared PDTs as templates
3. Build your product assuming auditability, traceability, and version control will be required

🏥 Integrating into Traditional Care Pathways

The challenge:

• Even with FDA clearance, many PDTs struggle with clinical adoption. Providers are already overburdened, and introducing a new tool—even a valuable one—requires time, training, and trust.

How to navigate it:

1. Create provider-facing workflows and dashboards
2. Offer companion services (e.g., onboarding, patient coaching)
3. Partner with early adopter clinics or specialists for real-world pilots

🧩 GTM Friction in Provider Systems

The challenge:

• Distribution is different when your “user” is the patient, but your buyer is the provider, payer, or employer. Aligning incentives, workflows, and billing often causes slow uptake.

How to navigate it:

1. Design for multi-stakeholder onboarding from the start
2. Align your product with existing CPT or HCPCS billing codes
3. Consider phased GTM: DTC or hybrid models can build traction while payer pipelines mature
