The name says it all. “Byondis” (pronounced “beyond this”), is about going beyond the standard of care to provide novel treatments with high efficacy and low systemic toxicity for patients with unmet medical needs.
Based in Nijmegen, the Netherlands, Byondis, an independent, privately held, clinical stage biopharmaceutical research and development company, started in 2012 as a biopharmaceutical subsidiary of Dutch-based generics pharmaceutical company Synthon. This subsidiary, called Synthon Biopharmaceuticals, quickly built a promising pipeline of innovative research and development programs with an aim to create innovative precision medicines targeting intractable cancers and autoimmune diseases.
In 2019, Synthon Biopharmaceuticals separated from Synthon, which resulted in the formation of a new independent company, which, in 2020, was rebranded as Byondis.
Creating Precision MedicinesWith a dedicated team of more than 400 employees, including highly educated scientists and skilled technicians working in state-of-the-art Research & Development and Good Manufacturing Practice (GMP) production facilities on its campus in Nijmegen, the Netherlands, Byondis creates both targeted and immuno-oncology [IO] therapies.
Byondis takes its innovative portfolio beyond the laboratory, from discovery, to preclinical research, to biopharmaceutical development/manufacturing, to proof-of-concept demonstrated in early-phase clinical trials. Byondis has a broad development pipeline built on proprietary technologies, with preclinical as well as early- and late-stage clinical development programs.
This pipeline reflects the company's expertise in research, lead identification, preclinical/clinical development, process development and manufacturing.
Byondis CEO Marco Timmers, Ph.D. explained: “We employ the latest insights in tumor biology and patient unmet needs in our search for and development of new mechanisms and new targets for monoclonal antibodies, ADCs and small molecule programs. Our aim is to have a solid pipeline with programs at different development stages.”
Antibody-Drug ConjugatesThe cornerstone of Byondis' research and development efforts are the company's next generation antibody-drug conjugates (ADCs). These targeted agents open the way for novel treatment options for patients diagnosed with cancer, including hematological malignancies. These ADCs aim to target difficult-to-treat cancers with powerful cytotoxins that have a wider therapeutic window and lower systemic toxicity. They are designed to destroy cancer cells and spare normal, healthy, cells. The therapies are based on Byondis' distinctive, proprietary technologies, novel mechanisms of action, and selected combination strategies.

The company entered into a License and Collaboration Agreement and a Supply Agreement with Germany-based medac, a privately held, global pharmaceutical company founded in 1970. medac will commercialize SYD985 in Europe and the United Kingdom, pending regulatory approvals. SYD985 was developed using Byondis’ ByonZine® and ByonNative® technologies.
New programs to enter clinical development, with preclinical data suggesting a promising therapeutic window in patients:
- BYON4228, this antibody (mAb) is the lead cancer immunotherapy from Byondis’ next generation IO program. The mAb targets SIRPα, which increases the tumour-killing capacity of the immune system.
- BYON4413 is an ADC directed against the molecular target CD123 (interleukin-3 receptor alpha chain), which is expressed in many hemato-oncological malignancies. Developed with Byondis ByonZine® and ByonShieLD® technologies, this investigational agent is currently in preclinical development. ADC Drug Map Link
- A linker-drug technology to generate IO ADCs.
- A linker-drug technology to generate ADCs with potential in both oncologic and other indications, such as autoimmune diseases
- A platform to increase the tumor-specificity of mAbs and ADCs.
Collaborative ResearchByondis regularly collaborates with leading global biotechnology and pharmaceutical companies, as well as many academic research institutions. While uniquely positioned to take its innovative portfolio beyond the laboratory, up to and including pivotal clinical studies, the company welcomes partners and collaborators to help speed its medicines to those who need them.
The ultimate goal: Making Hope Real for patients with a current unmet medical need.

ByonZine®Duocarmazine Linker-Drug Technology and cleavable DNA-damaging linker-drug. ADCs developed using this proprietary technology can effectively eliminate heterogeneous tumors via the unique target-mediated and bystander mechanisms of action and kills both dividing and non-dividing cancer cells with extremely low levels of free drug in circulation.
ByonNative®A differentiated antibody conjugation platform which allows ADC generation via partially reduced native disulfide bonds. This is a proprietary process that removes unwanted non-conjugated and over-conjugated species and enables fast generation of ByonZine® ADCs with antibodies of interest.
ByonShieLD®A site-specific antibody conjugation platform designed to create uniform ByonZine® ADCs via orthogonal cysteine activation and conjugation technology. Using a controlled method of connecting the linker-drug to the antibody, this technology shields the hydrophobic payload and creates ADCs with a superior therapeutic index and excellent manufacturability.
ByonFoLD®A dual linker-drug antibody conjugation platform designed to create well defined two-in-one ADCs in which two different payloads are conjugated in a compatible fashion to a single antibody. This technology allows the creation of next-generation ADCs with synergistically operating dual payloads.
ByonBranch®A branched linker technology. Branched linker technology allows the coupling of payloads to an antibody that results in ADCs with reduced hydrophobicity.
