MIIRA

The largest multi-modal data platform for early-stage cancer research

*Based on publicly available data

What real continuous response intelligence looks like.

Unlike other RWD built on single clinical encounters, MIIRA is multi-timepoint, linking an average of 9 longitudinal Signatera MRD timepoints per patient1 to native Altera WES/WTS* and clinico-genomic context, including:

  • H & E
  • Imaging
  • Treatments and Procedures
  • Clinical Outcomes

…across 450,000+ unique de-identified patient journeys for a truly complete and continuous view of cancer at both the molecular and clinical level.2

*or whole genome where available

Define your patient population before your trial does it for you.

All-Comer Population (IMvigor0103)

Kaplan-Meier disease-free survival curve comparing atezolizumab (n=406) and placebo (n=403), HR 0.89 (95% CI: 0.74, 1.08), P=0.25.

IMvigor010, an all-comer adjuvant study in MIBC, did not meet its primary DFS endpoint in the intent-to-treat population

In adjuvant and escalation settings, all-comer approaches risk diluting or obscuring treatment effects by including patients who do not need additional therapy.

Disease-free Survival (IMvigor0113)

Kaplan-Meier curve for ctDNA-positive patients: atezolizumab (n=167) reaches 44.7% at 12 months and 28.0% at 24 months versus placebo (n=83) at 30.0% and 12.1%.

IMvigor011 met its primary DFS and OS endpoints in ctDNA+ patients

Treatment on MRD (TOMR) approaches target the patients who may actually benefit from treatment initiation or escalation.

Use MIIRA to model TOMR and MRD-defined population scenarios well ahead of your trial to de-risk development decisions and identify patients with true unmet clinical needs.

New possibilities for clinical development and trials

Case Study – Curative-intent Trials

MRD-guided trial design
& patient matching

Identify MRD-guided patient populations for trial matching and enrollment, based on commercial Signatera data linked to real-world inclusion and exclusion criteria, to improve probability of trial success.

Read case study
Enrollment feasibility modeling funnel narrowing from N patients tested, to N Signatera MRD-positive, to N eligible patients, to N enrolled patients — 12–15 sites to enroll 40 patients in approximately 10 months.

Case Study – Metastatic Drug Development

Real-world comparator benchmarking for early-phase decision making

Generate regulatory-grade real-world control arms to benchmark against investigational therapies for earlier go-forward decisions.
