Who are we?

One2Treat is a fast-growing tech start-up based in Louvain-la-Neuve, Belgium.  We develop innovative solutions for biopharmaceutical companies to integrate multidimensional patient needs into clinical development steps and support holistic treatment decisions.  Born out of four years of advanced research within IDDI Group, One2Treat is now pioneering a new era of personalized healthcare.

One2Treat’s mission is to enable a more holistic evaluation of treatment effects by integrating all key patient-relevant outcomes into a single comprehensive assessment of the Net Treatment Benefit.

To this end, One2Treat is developing an integrated SaaS platform composed of multiple apps, designed to bring patient-centricity to the heart of clinical research. The first app, One2Treat Voice, focuses on capturing patient preferences through targeted surveys, helping identify and prioritize the outcomes that matter most to participants. The second app, One2Treat Insights, enables pharma R&D teams to analyze and interpret clinical trial data as well as inform and document strategic decision-making based on the totality of evidence from their randomized clinical trial data. By combining these tools, One2Treat supports smarter clinical trial design and more informed benefit-risk treatment assessments — ultimately aligning clinical development objectives with what truly matters to patients.
