Digital Therapeutics (DTx) 2026: The Complete Guide to Prescription Apps as Medicine

Table of Contents

Introduction – Why This Matters

In my experience working at the intersection of healthcare and technology, I’ve watched patients spend hundreds of dollars on wellness apps that promise better sleep, reduced anxiety, or improved diabetes control—only to abandon them after two weeks because they weren’t designed to deliver real clinical outcomes. Meanwhile, their doctors couldn’t recommend anything better because the evidence simply didn’t exist.

That landscape has fundamentally changed.

What I’ve found is that the most significant healthcare story of 2025-2026 isn’t a new blockbuster drug or a breakthrough surgical technique. It’s the quiet, evidence-driven rise of digital therapeutics (DTx) —prescription-quality software interventions that treat medical conditions through rigorously tested, clinically validated programs.

Consider this: by early 2026, over 50 prescription digital therapeutics have received FDA clearance or authorization, covering conditions from chronic insomnia to substance use disorder, from pediatric ADHD to migraine prevention. These aren’t lifestyle coaches or meditation timers. They’re regulated medical devices, often requiring a prescription, backed by randomized controlled trials, and increasingly integrated into insurance formularies alongside traditional pharmaceuticals.

The numbers tell a compelling story. The global digital therapeutics market, valued at approximately $6 billion in 2024, is projected to exceed $15 billion by 2027. But beyond the market size, what excites me is the clinical potential: digital therapeutics can reach patients where they live, scale infinitely without proportional cost increases, and address the behavioral and neurological foundations of disease that pills alone cannot touch.

This guide will walk you through everything you need to know about digital therapeutics—how they work, why they matter, what conditions they treat, and where this field is heading. Whether you’re a curious beginner wondering if that insomnia app your friend mentioned is legitimate, or a healthcare professional needing a refresher on the latest evidence, this article will give you a comprehensive, practical understanding of software as medicine.

Background / Context

The Digital Health Ecosystem: Finding Your Bearings

To understand digital therapeutics, we first need to place them within the broader digital health landscape. Think of digital health as an umbrella term covering any technology used in healthcare—telemedicine platforms, electronic health records, wearable devices, and countless mobile applications.

In my experience, most people (and even many healthcare professionals) lump everything together as “health apps.” That’s like calling both a children’s vitamin and a chemotherapy drug “medications.” The distinctions matter enormously for safety, efficacy, and regulatory oversight.

Here’s how the ecosystem breaks down:

Wellness Apps: These are the most common—Headspace, Calm, MyFitnessPal, Noom. They promote general well-being, stress reduction, or healthy habits. They’re regulated by the Federal Trade Commission (FTC) for truth in advertising, not by the FDA for clinical efficacy. They don’t make medical claims about treating disease, and they don’t require a prescription.

Companion Apps: These support pharmaceutical use—reminding patients to take medication, tracking side effects, and providing educational content. Companies like Sidekick Health and Dario Health offer these tools. They enhance adherence but don’t deliver therapeutic interventions themselves. The FDA’s Office of Prescription Drug Promotion regulates its promotional claims, but the apps themselves face minimal regulatory oversight.

Digital Therapeutics (DTx): This is where the line blurs between software and medicine. DTx products deliver evidence-based therapeutic interventions directly to patients. They’re regulated as medical devices, require FDA clearance (typically through 510(k) or De Novo pathways), and make specific claims about treating, managing, or preventing disease.

Prescription Digital Therapeutics (PDT): The gold standard within DTx. These require a prescription from a licensed healthcare provider, are cleared as Software as a Medical Device (SaMD), and have undergone the most rigorous clinical evaluation—often multiple randomized controlled trials.

Software-enhanced Drugs (SE Drugs): The newest category, enabled by the FDA’s 2024-2025 guidance on Prescription Drug Use-Related Software (PDURS). These are combination products where a drug and a digital therapeutic are co-packaged and prescribed together, creating a new digital formulation of an existing medication.

The Problem Digital Therapeutics Solve

Traditional medicine excels at targeting biological mechanisms. Pills reduce cholesterol, lower blood pressure, kill cancer cells, or block pain signals. But many chronic conditions have behavioral, cognitive, or neurological components that pharmaceuticals address poorly or not at all.

Take chronic insomnia. Sleeping pills can induce sleep, but they don’t teach the brain to stay asleep naturally. They don’t address the anxiety about sleep that perpetuates insomnia. They don’t rebuild healthy sleep architecture. Patients often relapse when medications stop.

Or consider chronic pain. Opioids may dull the sensation, but they don’t retrain the brain’s pain pathways, don’t address the fear-avoidance cycle that leads to disability, and don’t teach pacing strategies that prevent flare-ups.

What I’ve found is that the most successful digital therapeutics fill exactly these gaps. They deliver structured, evidence-based psychological interventions—cognitive behavioral therapy, acceptance and commitment therapy, biofeedback, neurocognitive training—through software that adapts to each patient’s needs and provides real-time feedback.

A Brief History

The concept of using computers for therapy isn’t new. Computerized cognitive behavioral therapy (cCBT) programs emerged in the 1990s, delivered on CDs or via early web platforms. But they were clunky, non-interactive, and couldn’t adapt to user responses.

The smartphone revolution changed everything. Suddenly, therapeutic interventions could travel in patients’ pockets, delivered through engaging interfaces with gamification elements, video content, and interactive exercises. The first wave of mental health apps appeared in the early 2010s, but most lacked clinical validation.

The turning point came around 2017-2018, when companies like Pear Therapeutics, Akili Interactive, and Click Therapeutics began pursuing formal FDA clearance for their products. Pear’s reSET for substance use disorder became one of the first FDA-authorized prescription digital therapeutics in 2017. Akili’s EndeavorRx for pediatric ADHD followed in 2020—the first game-based therapeutic cleared by the FDA.

By 2024-2025, regulatory frameworks had matured significantly. The FDA’s PDURS guidance opened pathways for integrating digital therapeutics with traditional drugs, recognizing that software could add clinically meaningful benefits to pharmaceutical interventions. Major pharmaceutical companies now actively develop or acquire digital therapeutic assets, viewing them not as competitors but as complementary tools that enhance outcomes and differentiate their products.

Key Concepts Defined

Before diving deeper, let’s establish clear definitions of essential terms. In my experience teaching these concepts to healthcare professionals and patients alike, confusion about terminology creates the biggest barrier to understanding.

Digital Therapeutic (DTx): Evidence-based software interventions intended to treat, manage, or prevent medical conditions. They deliver therapeutic interventions through software, are clinically evaluated, and typically require regulatory clearance. The Digital Therapeutics Alliance, the industry’s leading trade organization, has established core principles including peer-reviewed trial publication, regulatory review, and appropriate claims based on clinical status.

Software as a Medical Device (SaMD): A regulatory category defined by the International Medical Device Regulators Forum (IMDRF) and adopted by the FDA. SaMD is software intended to be used for medical purposes without being part of a hardware medical device. Most digital therapeutics fall under SaMD.

Prescription Digital Therapeutic (PDT): A digital therapeutic that requires a prescription from a licensed healthcare provider. These have typically undergone the most rigorous clinical testing and are cleared through FDA pathways like De Novo or 510(k).

Companion App: Software that supports the use of a pharmaceutical product—tracking adherence, providing education, or monitoring symptoms—but does not deliver a therapeutic intervention itself. These don’t require FDA clearance as medical devices.

Software-enhanced Drug (SE Drug): A combination product where a drug and a digital therapeutic are co-packaged and prescribed together, creating a distinct therapeutic with its own clinical claims and National Drug Code (NDC) .

Digital Health: The broad umbrella term covering all technology used in healthcare, including telemedicine, electronic records, wearables, analytics, and both wellness and therapeutic apps.

Randomized Controlled Trial (RCT): The gold standard for clinical evidence, where participants are randomly assigned to receive the intervention or a control (placebo, sham, or standard care). Leading digital therapeutics have published multiple RCTs in peer-reviewed journals.

De Novo Classification: An FDA pathway for novel medical devices that don’t have a predicate (similar existing device) on the market. Many first-in-class digital therapeutics have used this pathway.

510(k) Clearance: An FDA pathway for devices that are substantially equivalent to an existing legally marketed device. Some digital therapeutics with established predicate devices use this route.

How It Works (Step-by-Step Breakdown)

Understanding how digital therapeutics work requires looking at both the technology and the clinical workflow. Let me walk you through both perspectives.

The Clinical Workflow: From Prescription to Treatment

Step 1: Patient Identification and Prescription

A patient presents with a condition appropriate for digital therapeutic intervention—say, chronic insomnia lasting more than three months. Their healthcare provider, having identified that the patient is a candidate, writes a prescription for a specific DTx product, just as they would for a medication.

In my experience, this step represents a significant shift in clinical thinking. Prescribing software feels unfamiliar to many providers initially. But as evidence accumulates and integration with electronic health records improves, the process becomes more routine.

Step 2: Onboarding and Activation

The patient receives instructions for accessing the digital therapeutic—typically through a mobile app download followed by an activation code. The onboarding process includes:

Creating a secure account
Completing baseline assessments
Watching introductory tutorials about how the treatment works
Setting initial goals
Connecting any companion devices (wearables, Bluetooth scales, etc.) if applicable

Step 3: Structured Treatment Protocol

The patient engages with the therapy according to its prescribed regimen. Most digital therapeutics require short, daily interactions—typically 5-20 minutes per day. The content is structured, sequenced, and adaptive.

For example, a cognitive behavioral therapy for insomnia (CBT-I) digital therapeutic might deliver:

Week 1: Sleep education and diary tracking
Week 2: Stimulus control and sleep restriction instructions
Week 3: Cognitive restructuring for unhelpful beliefs about sleep
Week 4: Relapse prevention and maintenance planning

Step 4: Continuous Data Collection

Throughout treatment, the software collects data on engagement, progress, symptoms, and outcomes. This might include:

Session completion rates
In-app assessments (mood, pain, sleep quality)
Passive data from phone sensors or wearables
User-reported outcomes

Step 5: Adaptive Personalization

Machine learning algorithms analyze incoming data to personalize the experience. If a user struggles with a particular concept, the system might offer additional explanations or practice exercises. If they’re progressing rapidly, it might accelerate through modules. This adaptivity distinguishes modern DTx from static computerized therapy programs of the past.

Step 6: Provider Dashboard and Clinical Oversight

The prescribing provider can monitor patient progress through a secure clinical dashboard. They might see adherence rates, symptom trends, and alerts for deterioration or lack of progress. This enables asynchronous oversight and timely interventions—sending a message of encouragement, scheduling a check-in call, or adjusting the treatment plan.

Step 7: Outcomes Assessment and Treatment Completion

At prescribed intervals—often 6-12 weeks—the system reassesses outcomes against baseline. If treatment goals are met, the patient may complete the program with maintenance strategies. If not, the provider can consider alternative or adjunctive treatments.

The Technology Stack: What Makes DTx Work

Behind the user-friendly interface lies sophisticated technology:

Clinical Content Management: The therapeutic content—videos, interactive exercises, educational text, audio exercises—is structured within a content management system that ensures delivery follows the clinical protocol exactly.

Behavioral Tracking Engine: This captures user interactions, creating a detailed record of engagement that feeds into both clinical dashboards and adaptive algorithms.

Machine Learning Personalization Layer: Algorithms analyze user behavior and outcomes to optimize content sequencing, difficulty adjustment, and intervention timing.

Secure Data Infrastructure: All protected health information is encrypted, stored in HIPAA-compliant environments, and transmitted securely. This infrastructure must meet FDA cybersecurity requirements.

Provider Dashboard Interface: A separate interface gives clinicians visibility into their patients’ progress without requiring them to navigate the patient-facing app.

Integration APIs: Application programming interfaces connect the DTx to electronic health records, pharmacy systems, and insurance claims platforms, enabling seamless workflow integration.

Regulatory Pathway Example

Let’s trace how a hypothetical digital therapeutic for migraine prevention reaches the market:

Phase 1-2 Trials: The developer conducts early studies to establish safety, engagement, and preliminary efficacy signals. For a behavioral intervention, safety typically means absence of adverse effects—the software shouldn’t increase headache frequency or cause psychological harm.

Pivotal RCT: A large, multi-site randomized controlled trial compares the digital therapeutic plus standard care against standard care alone (or against a sham control app). The trial measures clinically meaningful outcomes—in this case, reduction in monthly migraine days. For Click Therapeutics’ CT-132 migraine program, their pivotal study involving over 500 patients demonstrated a mean reduction of 3 monthly migraine days over 12 weeks in the active treatment group compared to sthe ham control.

Regulatory Submission: With positive trial results, the developer submits a De Novo classification request to the FDA, presenting evidence of safety and efficacy, along with details of the software development process, quality management system, and cybersecurity protections.

FDA Authorization: Upon clearance, the product can be marketed with specific indications. The FDA may require post-market studies to confirm real-world effectiveness.

Clinical Integration: The product becomes available for prescription, often with an initial focus on specialized centers before broader adoption.

Why It’s Important

Addressing Unmet Clinical Needs

The importance of digital therapeutics becomes most apparent when you consider conditions where traditional medicine falls short.

Behavioral Health Access: Mental health provider shortages are acute across most of the United States and many other countries. Patients wait months for appointments—if they can find a provider at all. Digital therapeutics deliver evidence-based psychological interventions at scale, without requiring a therapist’s time for every session. A single clinician can oversee hundreds of patients using a DTx, intervening only when algorithms flag concerns.

Chronic Disease Self-Management: Conditions like diabetes, hypertension, and COPD require daily self-management behaviors—medication adherence, dietary choices, physical activity, symptom monitoring. Digital therapeutics provide structured support for these behaviors, with personalized feedback and reinforcement that’s impossible to deliver in brief clinic visits.

Neurological Conditions: For disorders like migraine, chronic pain, and insomnia, digital therapeutics target the neurological and behavioral mechanisms that pharmaceuticals don’t address. A migraine prevention DTx might combine stress reduction techniques, trigger identification, and cognitive restructuring around pain catastrophizing—interventions that reduce attack frequency through different pathways than prophylactic medications.

Scalability and Access

What I’ve found is that digital therapeutics’ greatest strength is their ability to scale without proportional cost increases. A pharmaceutical factory must scale physical production for every new patient. A digital therapeutic, once developed, can serve one patient or one million with minimal additional cost.

This has profound implications for healthcare equity. Rural patients, underserved populations, and those who cannot take time off work for frequent appointments can access evidence-based treatment from their smartphones. Language barriers can be addressed through translation and cultural adaptation of content. The economies of scale make this feasible in ways that training more clinicians cannot match.

Integration with Traditional Medicine

Digital therapeutics aren’t replacing traditional medicine—they’re making it more effective. The evidence increasingly shows that combining drugs with digital therapeutics produces better outcomes than either alone.

This integration takes several forms:

Adherence Support: Many digital therapeutics include features that improve medication adherence—reminders, education about why the medication matters, tand racking of side effects that might otherwise lead to discontinuation.

Behavioral Synergy: A diabetes patient might take metformin to lower blood glucose while using a digital therapeutic to improve dietary choices and increase physical activity. The medication and behavior change work through different mechanisms toward the same goal.

Early Intervention: Digital therapeutics can identify early signs of deterioration—through daily symptom tracking or passive data from wearables—enabling timely clinical intervention before crises develop.

Economic Value

Healthcare systems and insurers are increasingly embracing digital therapeutics because they demonstrably reduce downstream costs. A digital therapeutic that prevents migraine attacks reduces emergency department visits, medication use, and lost work productivity. An insomnia DTx that resolves chronic sleep problems reduces primary care visits for sleep complaints and potentially prevents or delays the onset of depression, which is strongly linked to insomnia.

The business model is evolving rapidly. Early digital therapeutics relied on direct-to-consumer sales or employer wellness programs. Now, they’re increasingly covered by pharmacy benefit managers and integrated into insurance formularies alongside traditional drugs. Software-enhanced drugs create particularly compelling economics—pharmaceutical companies can extend product lifecycles and differentiate their offerings through digital formulations, while payers get better outcomes for their medication spend.

Sustainability in the Future

Environmental Sustainability

Digital therapeutics offer environmental advantages over traditional pharmaceuticals. They require no chemical manufacturing, no plastic packaging, no cold-chain shipping, and no disposal of unused medications. A course of treatment delivered entirely through software has a carbon footprint orders of magnitude smaller than an equivalent pharmaceutical intervention.

As healthcare systems worldwide grapple with their environmental impact—healthcare accounts for approximately 4-5% of global greenhouse gas emissions—digital interventions represent a meaningful sustainability opportunity. The scalability of DTx means that the environmental benefit multiplies with each additional patient treated.

Economic Sustainability

The economic sustainability of digital therapeutics depends on demonstrating long-term value. Early evidence is promising. Studies show that digital therapeutics can reduce hospitalizations, emergency visits, and overall healthcare utilization for chronic conditions. For payers facing unsustainable cost growth, interventions that improve outcomes while reducing utilization are extremely attractive.

What I’ve found is that the most successful digital therapeutics will be those that integrate seamlessly into existing workflows and demonstrate clear return on investment within 12-24 months. Products that require providers to fundamentally change how they practice, or that take years to show financial benefits, will struggle to achieve scale.

Clinical Sustainability

Clinical sustainability means maintaining therapeutic benefit over time. For many conditions, digital therapeutics aim to create lasting behavioral and neurological changes that persist after active treatment ends. An insomnia patient who learns cognitive behavioral therapy skills retains those skills indefinitely, even if they stop using the app.

However, some patients may need booster sessions or ongoing support. Forward-thinking DTx companies are developing maintenance programs, periodic check-ins, and algorithms that detect relapse risk and trigger appropriate interventions.

The 2026 Landscape and Beyond

Looking at current trends, several developments will shape the future of digital therapeutics:

Regulatory Maturity: The FDA’s PDURS guidance has created clear pathways for drug-software combinations. In 2026, we’re seeing the first wave of software-enhanced drugs enter the market, with more in development. This regulatory clarity reduces uncertainty for developers and investors.

Payer Integration: Major insurers and pharmacy benefit managers have now established formal review processes for digital therapeutics, similar to their processes for pharmaceuticals. Products with strong evidence and clear economic value are increasingly covered as standard benefits.

Prescribing Infrastructure: Electronic health record systems are integrating DTx prescribing capabilities, making it as easy for providers to prescribe software as to prescribe pills. This infrastructure development is crucial for mainstream adoption.

International Expansion: While the US has led DTx adoption, European and Asian markets are rapidly developing their own regulatory frameworks and reimbursement pathways. The EMA in Europe and PMDA in Japan have both cleared multiple digital therapeutics.

Artificial Intelligence Integration: The next generation of digital therapeutics will leverage AI more extensively—for personalization, for predictive analytics that identify patients at risk of deterioration, and for natural language processing that enables more sophisticated therapeutic conversations.

Common Misconceptions

In my experience speaking with patients, providers, and even healthcare executives, several misconceptions about digital therapeutics persist. Let me address them directly.

Misconception 1: “Digital therapeutics are just apps—like my meditation app or fitness tracker.”

This is perhaps the most common misunderstanding. While digital therapeutics are delivered through apps, they differ fundamentally from wellness apps in several ways :

Feature	Wellness App	Digital Therapeutic
Clinical evidence	Minimal or none	Published RCTs in peer-reviewed journals
Regulatory status	FTC oversight only	FDA cleared/authorized as medical device
Medical claims	FDA cleared/authorized as a medical device	Makes specific treatment claims
Prescription required	No	Often yes
Provider involvement	None	Prescribing and monitoring
Intended use	General wellness	Treat/manage specific condition

Misconception 2: “They’re trying to replace doctors with computers.”

Digital therapeutics augment, not replace, clinical care. Every prescription digital therapeutic requires a licensed provider to prescribe and oversee treatment. The software handles the structured delivery of evidence-based interventions, freeing clinicians to focus on complex cases, diagnostic uncertainty, and the human connection that remains central to healing.

Misconception 3: “The evidence isn’t as strong as for drugs.”

This misconception stems from unfamiliarity with digital therapeutic research methods. In reality, leading digital therapeutics have undergone the same rigorous evaluation as pharmaceuticals—multiple randomized controlled trials, published in top-tier journals, with clinically meaningful endpoints.

The pivotal trial for Pear Therapeutics’ reSET for substance use disorder, published in JAMA, demonstrated significantly higher abstinence rates compared to treatment as usual. Akili’s EndeavorRx for pediatric ADHD, published in The Lancet Digital Health, showed statistically significant improvements in objective attention measures. The evidence base continues to grow, with dozens of completed and ongoing trials.

Misconception 4: “Insurance won’t cover them.”

While coverage was limited in the early years, the situation has changed dramatically. As of 2026, most major insurers have established coverage policies for digital therapeutics with strong evidence. Medicare and Medicaid coverage varies by state and product, but is expanding. Many digital therapeutics are now included in pharmacy benefit manager formularies, making them accessible to millions of patients.

Misconception 5: “Patients won’t stick with them.”

Adherence is a legitimate concern for any treatment, including digital therapeutics. However, well-designed DTx products incorporate numerous engagement features—gamification, personalization, progress tracking, reminders, and human coaching options. Published adherence rates for leading products often exceed 70-80% over typical treatment durations, comparable to or better than medication adherence for chronic conditions.

What I’ve found is that patients who understand the evidence behind their digital therapeutic and have clear expectations about the time commitment are much more likely to complete treatment. Provider endorsement and follow-up also significantly impact adherence.

Misconception 6: “Anyone can develop one—it’s just software.”

Developing a digital therapeutic that meets regulatory standards requires specialized expertise across multiple domains: clinical research, behavioral science, software engineering, quality management, regulatory affairs, and commercialization. The average cost to bring a prescription digital therapeutic through FDA clearance exceeds $50-100 million when accounting for failed attempts and the full development cycle. This is not a space for casual app developers.

Recent Developments (2025-2026)

Regulatory Evolution

The most significant recent development has been the maturation of the FDA’s approach to digital therapeutics. The Prescription Drug Use-Related Software (PDURS) draft guidance, finalized through 2024-2025, created clear pathways for software-enhanced drugs. This guidance clarified that when a digital therapeutic is combined with a specific drug, the combination can be marketed as a distinct product with its own clinical claims and National Drug Code.

This has opened enormous opportunities for pharmaceutical companies to extend product lifecycles and differentiate their offerings. A drug nearing patent expiration can gain new life as a software-enhanced combination with superior outcomes to the drug alone.

Evidence-Based Expansion

The past 18 months have seen the publication of numerous pivotal trials for digital therapeutics across therapeutic areas. Notable examples include:

Migraine Prevention: Click Therapeutics’ CT-132 completed a pivotal study with over 500 patients, demonstrating a mean reduction of 3 monthly migraine days compared to sham control—a clinically meaningful improvement comparable to some prophylactic medications .

Insomnia: Multiple CBT-I digital therapeutics have published long-term follow-up data showing sustained benefits 12-24 months after treatment completion, addressing concerns about the durability of effect.

Pediatric ADHD: Akili’s EndeavorRx has published real-world evidence studies confirming effectiveness in diverse populations beyond the original trial participants.

Substance Use Disorder: Pear’s reSET and reSET-O have accumulated extensive real-world evidence supporting their effectiveness in community treatment settings.

Commercial Integration

Major pharmacy benefit managers, including CVS Caremark, Express Scripts, and OptumRx, have now established formal digital therapeutic formularies. This means that when a provider prescribes a covered digital therapeutic, the patient’s insurance processes it through the pharmacy benefit, often with standard copays.

This integration into existing pharmacy infrastructure has been a game-changer for adoption. Providers prescribe through the same systems they use for drugs, patients pick up their “prescription” through familiar pharmacy channels, and payers manage coverage through established processes.

International Expansion

The European Medicines Agency (EMA) has accelerated its digital therapeutic assessments, with multiple products receiving CE marking under the new Medical Device Regulation. Germany’s DiGA (Digital Health Applications) fast-track approval pathway has approved dozens of products, making them reimbursable by statutory health insurance .

Japan’s PMDA has also cleared multiple digital therapeutics, with a particular focus on products addressing the health needs of an aging population.

AI Integration Advances

The integration of artificial intelligence into digital therapeutics has advanced significantly. Modern DTx products increasingly feature:

Adaptive Algorithms: Machine learning models that adjust treatment intensity and content based on real-time user response .

Predictive Analytics: Algorithms that identify patients at risk of dropout or deterioration, enabling proactive provider intervention.

Natural Language Processing: More sophisticated conversational agents that can engage in therapeutic dialogue, though still within carefully controlled parameters.

Multimodal Data Integration: Combining user-reported outcomes with passive data from phone sensors and wearables to create comprehensive patient profiles .

Success Stories

Case Study 1: Pear Therapeutics and Substance Use Disorder

Pear Therapeutics’ reSET, authorized by the FDA in 2017 for substance use disorder, represents one of the earliest and most thoroughly documented DTx success stories. The product delivers the Community Reinforcement Approach combined with contingency management—evidence-based behavioral interventions traditionally delivered in intensive outpatient settings.

In a pivotal trial published in JAMA, patients using reSET plus standard care showed significantly higher abstinence rates (42.6%) compared to standard care alone (27.9%). They also had higher treatment retention rates. Subsequent real-world evidence studies with tens of thousands of patients confirmed these findings in community treatment settings.

What I’ve found particularly impressive about the reSET story is how it integrated into existing addiction treatment workflows. Rather than requiring clinics to fundamentally change how they operate, reSET supplemented group and individual therapy with between-session support, extending the reach of counselors and reinforcing therapeutic concepts during vulnerable moments.

Case Study 2: Akili Interactive and Pediatric ADHD

Akili’s EndeavorRx made history in 2020 as the first game-based therapeutic cleared by the FDA. Designed for children aged 8-12 with ADHD, the product delivers targeted sensory stimuli and motor challenges designed to activate specific neural networks involved in attention.

In a multi-site randomized controlled trial involving 348 children, those using EndeavorRx showed statistically significant improvements on the Test of Variables of Attention (TOVA), an objective measure of attention, compared to a control group playing a different game. Importantly, the effect was achieved without the side effects common to ADHD medications—appetite suppression, sleep disturbance, growth suppression.

Since launch, real-world evidence studies have confirmed effectiveness in diverse populations, and the product has expanded to include adult indications. Akili’s success demonstrated that digital therapeutics could address neurological conditions previously thought responsive only to medication.

Case Study 3: Click Therapeutics and Migraine Prevention

Click Therapeutics’ CT-132 program for migraine prevention illustrates the sophisticated evidence generation expected of modern digital therapeutics. The pivotal trial enrolled over 500 patients across multiple sites—a scale comparable to pharmaceutical migraine trials.

The results, announced in 2025, showed a mean reduction of 3 monthly migraine days in the active treatment group compared to sham control over 12 weeks . This effect size is clinically meaningful and comparable to some prophylactic medications, but without the side effect burden. The intervention combines stress reduction techniques, trigger identification and management, and cognitive restructuring around pain catastrophizing.

What excites me about this program is that it targets the neurological and behavioral components of migraine that medications don’t address. Many migraine patients experience attacks triggered by stress, sleep disruption, or dietary factors. A digital therapeutic that helps them identify and manage these triggers can reduce attack frequency through different mechanisms than prophylactic drugs, potentially offering additive or synergistic benefits.

Case Study 4: Software-enhanced Drugs in Development

The most exciting emerging success stories involve software-enhanced drugs—combinations where digital therapeutics and pharmaceuticals are co-packaged and prescribed together. Several major pharmaceutical companies have programs in late-stage development.

For example, a partnership between Otsuka Pharmaceutical and Click Therapeutics is developing a software-enhanced version of a known medication for major depressive disorder. The digital component delivers behavioral activation therapy—an evidence-based psychological intervention that complements the medication’s biological effects. Early studies suggest the combination produces faster response and higher remission rates than either treatment alone .

This approach represents the ultimate integration of digital and traditional medicine: two evidence-based treatments, each targeting different mechanisms, delivered together as a unified therapeutic.

Real-Life Examples

Example 1: Sarah’s Insomnia Journey

Sarah, a 45-year-old marketing executive, had struggled with chronic insomnia for eight years. She’d tried multiple sleeping pills—zolpidem, eszopiclone, trazodone—but either experienced morning grogginess, developed tolerance requiring dose escalation, or relapsed when discontinuing. Her primary care provider referred her to a sleep specialist, but the wait was six months.

During a routine visit, her provider mentioned a new option: a prescription digital therapeutic delivering cognitive behavioral therapy for insomnia (CBT-I). Sarah was skeptical—how could an app fix something pills couldn’t?—but agreed to try.

The program required 20 minutes daily for eight weeks. Week one focused on sleep education and diary tracking. Week two introduced stimulus control: get out of bed if unable to sleep, use the bed only for sleep and sex. Week three added sleep restriction: temporarily limiting time in bed to increase sleep efficiency. Week four addressed cognitive restructuring around unhelpful beliefs about sleep.

What I’ve found remarkable about cases like Sarah’s is the transformation. By week six, her sleep efficiency had increased from 65% to 85%. By week eight, she was sleeping 7.5 hours nightly without medication. At six-month follow-up, improvements persisted. She’d learned skills that continued working long after the app use ended.

Example 2: David’s Migraine Management

David, a 32-year-old software developer, experienced 12-15 migraine days monthly. Two different prophylactic medications had failed—one due to inefficacy, another due to cognitive side effects that interfered with his work. He was considering giving up on prevention and just treating acute attacks, which meant frequent medication use and significant disability.

His neurologist enrolled him in a clinical trial of an investigational digital therapeutic for migraine prevention. The program combined daily stress reduction exercises, trigger identification and management, and cognitive restructuring around pain catastrophizing. It also integrated with his existing medication regimen, reminding him to take acute medications appropriately and tracking their effectiveness.

Over 12 weeks, David’s migraine days dropped from 14 per month to 6. He learned to identify early warning signs—neck tension, yawning, food cravings—and intervene before full attacks developed. He reduced his acute medication use by 60%. Two years later, now using the commercially available version, improvements persist.

Example 3: Maria’s Diabetes Support

Maria, a 58-year-old with type 2 diabetes, struggled with glycemic control despite taking metformin and glipizide. Her HbA1c remained above 8.5%, putting her at risk for complications. Her endocrinologist prescribed a digital therapeutic focused on diabetes self-management.

The program included dietary tracking with personalized feedback, physical activity coaching, medication reminders, and educational content about carbohydrate counting and blood glucose patterns. It integrated with her continuous glucose monitor, providing real-time feedback about how food choices affected her glucose levels.

Within three months, Maria’s HbA1c dropped to 7.2%. She’d lost 12 pounds through dietary changes. She understood how different foods affected her glucose and could make informed choices rather than following generic meal plans. The program didn’t replace her endocrinologist—she still saw him quarterly—but it provided daily support that no clinic visit could match.

Most digital therapeutics require short, daily engagement—typically 5-20 minutes per day—over weeks or months. The total treatment duration depends on the condition and specific product, usually ranging from 6-16 weeks .

Q7: Are digital therapeutics safe?

FDA-authorized digital therapeutics have undergone safety evaluation as part of regulatory review. For behavioral interventions, safety concerns are typically minimal, though some patients may experience frustration or mild distress when confronting challenging material. Serious adverse events are rare .

Q8: Can digital therapeutics replace my medication?

Sometimes yes, sometimes no. Some digital therapeutics are intended as standalone treatments. Others work alongside medications to enhance effects. Never discontinue prescribed medication without discussing with your provider .

Q9: How do I know if a digital therapeutic works for my condition?

Look for products with published randomized controlled trials in peer-reviewed journals. Regulatory clearance (FDA, EMA) provides assurance that the product has met minimum standards for safety and efficacy. Your provider can help interpret the evidence for your specific situation .

Q10: What’s a software-enhanced drug?

A software-enhanced drug combines a pharmaceutical and a digital therapeutic in a single prescription. The drug and software work together, with the digital component adding clinically meaningful benefit beyond the drug alone. These combination products have their own National Drug Codes and clinical claims .

Q11: How do providers monitor my progress with a digital therapeutic?

Most prescription digital therapeutics include provider dashboards that show adherence, symptom trends, and outcomes. Your provider can review this data asynchronously and intervene if concerning patterns emerge—sending a message, scheduling a visit, or adjusting treatment .

Q12: What happens if I stop using the app?

Treatment effects depend on consistent engagement. If you stop using the app, you won’t receive the full therapeutic benefit. Some skills learned may persist, but most digital therapeutics are designed for completion of the full treatment protocol. Contact your provider if you’re struggling with adherence .

Q13: Are digital therapeutics covered by Medicare or Medicaid?

Coverage varies by state and product. Some digital therapeutics have secured Medicare coverage through specific pathways. Medicaid coverage is expanding but inconsistent across states. Check with your plan or the product manufacturer for current coverage status .

Q14: How are digital therapeutics regulated outside the United States?

The European Medicines Agency (EMA) and national authorities in Europe clear digital therapeutics through the Medical Device Regulation. Germany’s DiGA pathway provides fast-track access. Japan’s PMDA has cleared multiple products. Regulatory frameworks are developing globally .

Q15: Can children use digital therapeutics?

Some digital therapeutics are specifically designed and cleared for pediatric populations—Akili’s EndeavorRx for ADHD in children ages 8-12 is a prominent example. Others are indicated only for adults. Check the product’s cleared indications .

Q16: What’s the difference between 510(k) clearance and De Novo classification?

510(k) clearance applies to devices substantially equivalent to an existing legally marketed device. De Novo classification is for novel devices without a predicate. Many first-in-class digital therapeutics use the De Novo pathway, establishing new categories for future products .

Q17: How do digital therapeutics protect my privacy?

FDA-authorized digital therapeutics must meet stringent cybersecurity and data privacy requirements. They’re subject to HIPAA regulations (in the US), encrypt data in transit and at rest, and must maintain comprehensive security programs. Review each product’s privacy policy for specifics .

Q18: Can I use a digital therapeutic if I don’t have a smartphone?

Most digital therapeutics require a smartphone or tablet. Some offer web-based access through computers, but mobile delivery is typical. If you lack compatible devices, discuss alternatives with your provider .

Q19: How much do digital therapeutics cost without insurance?

Costs vary widely. Some direct-to-consumer products may cost $50-100 monthly. Prescription digital therapeutics can cost hundreds or thousands for a treatment course without insurance. However, coverage is increasingly common, reducing out-of-pocket costs .

Q20: Do digital therapeutics work for severe cases?

Evidence varies by product and condition. Some digital therapeutics have been studied primarily in mild-to-moderate populations. Others, like those for substance use disorder, have demonstrated effectiveness in severe cases. Discuss severity with your provider when considering DTx options .

Q21: What if I need human support while using a digital therapeutic?

Many digital therapeutics include coaching or support options—access to trained specialists who can answer questions and provide encouragement. Even without built-in coaching, your prescribing provider remains available for support. Digital therapeutics augment, not replace, the human elements of care .

Q22: How are digital therapeutics different from teletherapy?

Teletherapy involves live sessions with a therapist via video. Digital therapeutics deliver structured, automated interventions that patients complete independently. Some products combine both—automated content plus periodic coaching or therapy sessions. Teletherapy scales through provider time; digital therapeutics scale through software .

Q23: Can digital therapeutics cause side effects?

Side effects from behavioral interventions are typically mild—frustration, temporary discomfort when confronting challenging material, or time burden. Some digital therapeutics include safety monitoring for deterioration. Unlike medications, they don’t cause physiological side effects like nausea or sedation .

Q24: Where is the field heading in the next 5 years?

Expect continued integration with traditional medicine (more software-enhanced drugs), expansion into new therapeutic areas, international regulatory harmonization, deeper AI integration for personalization, and routine coverage by insurers. Digital therapeutics will become a standard tool in clinicians’ arsenals, prescribed alongside—and sometimes instead of—traditional medications .
