📌 Definition

Digital Therapeutics (DTx) are evidence-based, software-driven therapies that prevent, manage, or treat a medical disorder or disease — delivered to patients via mobile or web apps, often prescription-only, often FDA-cleared. AI-augmented DTx in 2026 includes personalized therapy adjustment, AI-driven engagement, predictive adherence modeling, and clinical decision support for the prescribing clinician. Production DTx engineering requires FDA SaMD pathway compliance, randomized clinical trial infrastructure, payer-grade evidence generation, EHR integration via FHIR, and HIPAA-compliant BAA-covered cloud. Productized fixed-price tiers: $45K (4-week Discovery), $95K (8-week Production-Ready), $145K (12-week FDA-pathway Pilot-Ready).

What we build for DTx companies

Prescription-grade patient apps

Native iOS and Android plus web. Prescription unlock workflows, clinician-prescribed protocols, adherence tracking, in-app therapy delivery. WCAG 2.2 accessibility.

AI personalization engine

Adaptive therapy adjustment based on patient response. Reinforcement learning for engagement optimization. RAG-grounded clinical content. Override-and-audit-logged.

Clinician portal

Prescriber dashboard for protocol management, patient progress monitoring, intervention queues, and clinical decision support. Role-based access.

Clinical trial infrastructure

RCT-grade data collection, randomization engines, blinding workflows, eCRF integration, ePRO/eCOA collection, 21 CFR Part 11 compliance.

Real-world evidence (RWE) generation

Production data pipelines feeding RWE studies. De-identification, cohort matching, outcome tracking, payer-grade evidence packaging.

FDA SaMD pathway support

$30K productized FDA SaMD pathway assessment. Predicate device research, risk classification, design history file structure, 510(k) or De Novo submission support.

Payer integration infrastructure

Eligibility verification, prior authorization workflows, prescription validation, claims-grade outcomes reporting for value-based contracts.

EHR integration

FHIR R4 integration via SMART on FHIR. Prescription writes via CDS Hooks. Outcomes write-back to clinician inbox. Epic, Cerner-Oracle, Athena, Allscripts.

FAQs

FAQ

It depends on whether the DTx is prescription-only (Rx-DTx) or non-prescription wellness. Rx-DTx that diagnoses, treats, or prevents disease usually requires FDA SaMD pathway — 510(k), De Novo, or PMA. Non-prescription wellness apps with AI features usually don’t. We provide a productized $30K FDA SaMD pathway assessment on every engagement where this is a question.

Adaptive personalization in an FDA-regulated DTx requires a Predetermined Change Control Plan (PCCP) filed with FDA. The PCCP defines what the model is allowed to adjust (engagement sequencing, content selection) versus what requires a new 510(k) (the underlying therapy protocol). We build PCCP-aligned model architectures from day 1.

Yes. SMART on FHIR launch from inside Epic, Cerner-Oracle, Athena, or Allscripts. CDS Hooks for in-workflow prescription. Outcomes write-back to clinician inbox or care plan. This is what separates production DTx from wellness apps — the clinician can prescribe, monitor, and adjust without leaving the EHR.

Three dominant patterns in 2026: (1) prescription-grade benefit covered like a pharmaceutical, (2) value-based contracts paid on outcomes (adherence, A1C reduction, ED visits avoided), (3) per-member-per-month (PMPM) employer contracts. The evidence infrastructure required for each is different; we scope per engagement.

Randomized controlled trial-grade data collection — randomization engines, blinding workflows, eCRF integration, ePRO/eCOA collection, 21 CFR Part 11-compliant audit trails. Most DTx companies need this infrastructure for their pivotal trial and for ongoing RWE generation post-launch.

Yes. MDR/IVDR-compatible documentation patterns are included on every engagement. We can ship US-first and add EU expansion later, or build for both markets from day 1. The 510(k) and MDR pathways have overlapping documentation but non-identical requirements.

4-week Discovery, 8-week Production-Ready, 12-week Pilot-Ready. Full production with FDA SaMD pathway adds 16–32 weeks. Pivotal RCT infrastructure adds 8–16 weeks depending on protocol complexity.
