Our story

A single conviction, carried for a decade.

It began with a simple belief: precision RNA-targeted medicine could be made more effective and fundamentally safer. Over time, that belief shaped our science, became a platform, a growing pipeline, and a team working to bring these ideas into the clinic.

FRFilip Rázga
Founder's message
"We never accepted that side effects should be the unavoidable price of effective therapy. At Selecta, we are working to change that by developing oligonucleotides that are designed to be highly target-specific, with safety at their core. Ultimately, it is about giving patients better treatment options."

Chief Executive Officer
Our mission

To improve patient healthcare through safer therapeutic solutions, delivering the desired therapeutic effect while helping patients maintain their quality of life.

Excellence-driven commitment to your health has guided every decision we have made for more than a decade.

Our journey

Key milestones, from bench to the clinic.

From the first peer-reviewed studies to therapeutic leads advancing toward first-in-human trials.

2011 — 2018 · The science

A foundation in deep science.

More than a decade of research into unique oligonucleotide architecture, supported by peer-reviewed publications, laid the scientific foundation for everything that followed.

2016

CML research: understanding the disease biology

Extensive research into chronic myeloid leukemia, from predictive biomarkers to the identification and characterization of CML stem cells.

2017

Selective therapeutic intervention

Framing the central challenge that would shape our work: achieving therapeutic activity with greater precision and fewer off-target effects.

2018

"Chronic myelogenous leukemia on target"

Publication in Cancer Medicine marks a key step in our research. In the same year, Selecta Biotech SE is established in Bratislava as a European company (SE).

2020 — 2023 · Platform & recognition

ESiNAR-X®, validated.

Our patented platform takes shape and earns European recognition, while certification and partnerships build the foundation for clinical translation.

2022

A tailor-made antiviral against SARS-CoV-2

An ESiNAR-X®-derived oligonucleotide demonstrated effective reduction of SARS-CoV-2 RNA levels, leading to the launch of the ASC1R therapeutic program.

2022

Best MedTech Innovation of the Year – EU

Recognised at the Research & Development Awards, alongside Young Biotechnology Company of the Year at the Innovation & Excellence Awards.

2023

Best innovation in medical technology & ISO 9001

Recognized at the Innovation & Excellence Awards and achieved ISO 9001 certification for quality management in research and development.

2024 — 2026 · Toward the clinic

From platform to pipeline.

Therapeutic leads advance across oncology, infectious and renal diseases as Selecta expands its collaborations across Europe.

2024

ASP210 & ASC1R advance

ASP210 shown effective against TKI-resistant CML cells; ASC1R demonstrates excellent tolerability and efficacy in vivo.

2025

Strengthening our international visibility

Presence at MEDICA 2025 in Düsseldorf and the OTS Annual Meeting – marking another step toward clinical impact.

2026

From Bratislava to Basel

Engaging Europe's biotech investment ecosystem at Swiss Biotech Day, as our lead programs approach the clinic.
