Introduction

Animal testing has long been the foundation of drug development — yet nearly 90% of drugs that pass those tests still fail in human trials. With advances in AI, stem cell science, and regulations like the FDA Modernization Act 2.0, the life sciences industry is rethinking how preclinical testing should really work.

That’s why our experts from Quantiphi and Transcell Biologics discussed DART (Digital Animal Replacement Technology) in the pilot episode of the Phi Moments podcast. They explored how DART — an AI- and stem cell–based platform — is transforming preclinical research by delivering faster, more human-relevant insights.

This blog highlights key takeaways from their conversation. Catch the full discussion below to discover how DART is shaping the future of preclinical research.

The Problem with Traditional Preclinical Testing

Animal models have been the cornerstone of preclinical testing, but they bring several limitations:

Poor human translatability – Drugs safe in animals often fail in humans.
Ethical concerns – Growing public and regulatory pressure against animal testing.
High costs and long timelines – Animal studies are resource-heavy and slow.
Regulatory shifts – With the FDA phasing out animal testing requirements for biologics, the industry urgently needs scalable alternatives.

The message is clear: the future of drug discovery depends on human-relevant, non-animal testing solutions.

The Spark Behind DART

The idea for DART was born during the COVID-19 pandemic, when a global shortage of monkeys brought vaccine testing to a standstill. Dr. Subhadra Dravida, CEO of Transcell Biologics, recognized that the industry needed more than a workaround—it needed an enterprise-grade platform to replace animal models altogether.

By combining human stem cell biology with AI and ML-driven analytics, DART emerged as a digital, workstation-ready platform capable of redefining preclinical testing.

What is DART and How Does It Work?

DART is built on human microphysiological systems (hMPS) derived from ethically sourced primary stem cells. These biological models are paired with Quantiphi’s AI-powered vision analytics, which can classify and score over 10 million stem cell phenotypes.

Key capabilities include:

Real-time toxicity and potency evaluation
Gene and protein sequence analysis
Image analytics of drug-cell interactions
Cloud and on-premises deployment for seamless integration

Unlike animal models, DART generates directly human-relevant data—reducing risk, cost, and development timelines.

What Makes DART Different?

DART stands apart by addressing scientific, operational, and ethical pain points in one integrated platform:

Human-relevant insights – Based on human biology, not species approximations.
AI-driven scalability – Deep learning ensures reproducibility and faster qualification.
Regulator-ready design – Supports early-stage screening through IND-enabling studies.
Modular and accessible – Deployable without additional infrastructure or data science teams.

With DART, drug developers can make smarter, faster go/no-go decisions and improve their odds of success in clinical trials.

Real-World Impact of DART

DART is already making a global impact:

Partnered with 15+ pharma and biotech firms
Piloted across 20+ use cases
Secured 8 international patents

Case Highlights:

A global vaccine manufacturer validated immune responses when legacy models failed.
A U.S. biotech selected oncology IND candidates using patient-derived tumor models.
One customer received FDA approval using DART-generated data—proving regulatory acceptance.

Beyond pharma, DART is expanding into cosmeceuticals and agrochemicals, industries long dependent on animal testing.

Benefits of DART for Pharma & Biotech

DART delivers value across the entire drug development pipeline:

Early-stage applications:

Molecule library screening
Lead prioritization
Mechanism-of-action validation
Biosimilarity and residual toxicity checks
Antigenicity and immunogenicity profiling

Later-stage applications:

IND-enabling studies
Potency bioassays and safety pharmacology panels
Clinical surrogate data for regulatory submissions
Batch release readiness

Business impact:

30% faster early-stage screening
Reduced R&D costs by eliminating weak candidates earlier
Smarter cohort design and patient matching for precision medicine

Implementation: How to Get Started

Getting started with DART is simple and scalable:

Discovery workshop (1 week) – Align on testing goals.
Pilot program – Modular proof of concept.
Scale-up – Integration across products and pipelines.

Deployment options:

Insourced (on-prem/cloud workstation)
Outsourced (testing at certified facilities)

Many customers have gone from pilot to production in under six months.
