Human-first medicine, built on genetically diverse iPSCs and tissues

Drug discovery is saturated: ~86% of GWAS participants are of European ancestry, yet Asia is 60% of humanity where there are still plenty of genetic variants to explore. Varios consolidates the largest Asian iPSC biobank — deep-phenotyped donors across Southeast Asian ancestries — into a multi-omic discovery engine for pharma, biotech, and AI.

Platform technology

Five layers, compounding into a human-first discovery engine.

Population-scale cells, multi-modal data, disease-relevant phenotypes, ground-truth tissues — converging on a discovery pipeline that learns from each new donor.

02 · DATA

Multi-Modal Datasets

Cellular function, cellular and clinical -omics, EHR, and imaging — layered on the same donors. The density that drives novel insights and de-risks decisions.

  • Cellular function (eg. Electrophysiology & contractility)
  • WGS · RNA-seq · ATAC · proteomics · metabolomics
  • Longitudinal clinical phenotyping
  • High-content imaging
03 · MODELS

iPSC Disease Models

Patient-derived iPSC disease models with phenotyping calibrated to serve as proxies for clinical endpoints — so validation happens in human biology, not in species that don’t translate.

  • Cardio · metabolic · neuro
  • Endpoint-anchored phenotypes
  • Donor-matched to clinical data
04 · TISSUES

Human Tissues

Healthy and diseased human tissues — the ground-truth reference that anchors every cellular and computational readout back to real patients.

  • Donor-linked to iPSCs & -omics
  • Imaging, histology, spatial -omics
05 · DISCOVERY

Drug Discovery Pipeline

Where the platform culminates. The same iPSCs that power discovery also support patient stratification, toxicity prediction, and pharmacogenomics — end-to-end human context from target to trial.

  • Patient stratification
  • Human-context toxicity
  • Pharmacogenomics in-cell
SEC · 03 / APPROACH
How it works

Discovery. Validation. Prediction.

A closed-loop engine that links population-scale genetics to patient-derived cells — and patient-derived cells back to real clinical phenotypes.

01 · Discovery

Reverse-engineering clinical endpoints.

We identify indications and clinical endpoints that associate well with cellular phenotypes. We combine multi-ancestry GWAS, clinical cohorts, and cellular data for genetically-supported, actionable targets that have the best chance of affecting endpoints.

02 · Validation

Functional mechanism in patient-relevant cells.

Our iPSC library recapitulates clinical phenotypes — molecular markers, cellular dysfunction, drug response — so we validate targets where it matters.

03 · Prediction

Responder populations, before the trial.

Integrated ML on genotype × phenotype × cellular response predicts who benefits, informing smaller, faster, more precise clinical studies.
