The platform

Ultra-sensitive ctDNA delivered your way.

Five reasons researchers, pharma teams and clinics across Europe choose to work with us. Each pillar is a customer outcome first, a Simsen capability second.

01

SENSITIVITY

You detect signal at parts-per-million, in samples your current platform calls negative.

SiMSen-Seq chemistry, with duplex molecular barcoding and error suppression, separates true variants from background noise at variant allele frequencies below 0.001%. That is the regime where most ctDNA platforms run out of resolution and start returning false negatives.

For minimal residual disease monitoring, that resolution is what determines whether you see a relapse three months before imaging does, or three months after the patient does. For early-stage and paediatric samples, with low tumour burden in low blood volume, it is what determines whether you can run the assay at all.

This is the foundational claim under everything else on the platform. Without it, the rest does not matter.

 

02

FLEXIBILITY

You choose: send samples to our accredited lab, or run SiMSen-Seq on your own instruments.

Two delivery models. Same chemistry, same sensitivity, same data quality. The decision is operational, not scientific.

Send samples to the Simsen lab when you want the turnaround, the accreditation envelope and the interpretation done for you. Bring SiMSen-Seq in-house with LabSuite when you have the bench capacity, want full control of the workflow, or are running volumes that justify an internal pipeline.

Most customers start with one and add the other. Pharma partners often run discovery samples in-house and route confirmatory MRD work to the accredited lab. Translational groups often do the opposite.

This is the foundational claim under everything else on the platform. Without it, the rest does not matter.

 

03

CLINICAL INSIGHT

You see actionable variants and tumour evolution, not just a binary positive or negative.

The output is a clinical view of what is happening in the tumour, not a flag in a database.

Personalised ctDNA panels track the variants that matter for the individual patient and the tumour type, and surface resistance markers and clonal evolution over time. The report is built for the people reading it: clinicians, principal investigators, study teams. Each variant has a clinical rationale, not just a score.

If the question is "is there residual disease, yes or no", we will answer it. If the question is "what is the tumour doing now, and what should we change", the platform was built for that one.

 

04

TRANSPARENCY

You get full raw data access and an open analysis pipeline. Your bioinformatics team can verify, reanalyse or extend our results with their own tools.

No black-box scoring. No hidden variant call adjustments. The pipeline is open, the assumptions are documented, and the raw data is yours.

For translational research groups and pharma analytics teams, this is non-negotiable. You need to be able to reproduce the call, run a second pipeline against the same data, and publish without a vendor sitting between you and the result. We work that way by default.

It also means we get told when our pipeline is wrong. We prefer that to the alternative.

 

05

PARTNERSHIP

You work with a specialist team: co-publication, protocol design and interpretation help.

A small team of ctDNA specialists, in your time zone, who have already run samples like yours.

Co-authorship on the resulting paper, where the science supports it. Protocol design help up front, when an early conversation can save a sample run later. Interpretation help when a result is unusual and you want a second set of eyes on it.

We are not the right partner for every project. We are an exceptionally good partner for the ones we are right for.

In your language

The same five pillars sound different depending on who is reading them.

Each Solutions page retells these pillars in the language of the people on that side of the bench. Pick yours

For clinical trials

Cost saving on trial arms, MRD endpoints that hold up, co-publication.

The five pillars in pharma and CRO terms: cohort-level cost saving, validated MRD endpoints, regulatory readiness in the EU, raw data for your analytics teams, and co-authorship on the resulting paper.

For research & Labs

Low-AF detection, instrument-agnostic kits, raw data, co-authorship.

The five pillars in translational oncology terms: detection in paediatric and early-stage samples, LabSuite on the instruments you already own, full pipeline transparency, and shared bylines.

For clinics

Premium monitoring, lead time over imaging, EU logistics, real support.

The five pillars in clinic terms: personalised ctDNA monitoring for individual patients, earlier signal than imaging, EU logistics across the Nordics, DACH, UK and Spain, and a specialist team that picks up the phone.
