Resistance Capacity Report

We quantify evolutionary resistance capacity from sequencing you already ordered. Patient-level tiers, cohort summaries, and protocol implications — delivered in days, not months.

Sponsors don't lack drugs. They lack a number at day one.

Oncology teams know intratumour heterogeneity matters — but ITH on a sequencing report rarely becomes a trial-actionable capacity score before first-line therapy starts.

Does this tumour have the evolutionary capacity to learn resistance reliably — and how fast?

Today that question is answered reactively: wait for progression, sequence the relapse, switch therapy, repeat. The Resistance Capacity Report answers it proactively from outputs already in the genomic report.

Two sequencing inputs. One plain-language report.

No new assay. No proprietary mutation panel. No trial-specific infrastructure.

ITH index

Fraction of somatic mutations that are subclonal — already reported by your sequencing vendor. Captures how much evolvable signal is present.

CCF variance

Variance in cancer cell fraction across subclonal clusters — from standard clonal architecture analysis. Captures evolutionary learning capacity.

Each patient receives a capacity tier with protocol implications:

Low capacity Moderate capacity High capacity

Simple for your team. Rigorous under the hood.

  1. 1
    Send a de-identified export Patient ID, ITH fraction, and CCF variance per assessment — a simple spreadsheet from your CRO or sequencing vendor.
  2. 2
    We score and benchmark Each patient is assigned a capacity tier and compared against published NSCLC and cross-cancer reference profiles.
  3. 3
    You receive a report Cohort summary, per-patient capacity tiers, plain-language interpretations, and recommended next steps for trial planning.

Built on data sponsors already trust.

Fully anonymized case study using published aggregates and public cohorts — no client data required to evaluate the method.
