Numeric Biotech

“Developing therapeutics to cure and prevent age-related diseases”
So to further extend numeric age while living in good health

Numeric Biotech

The vision of Numeric Biotech is to build an innovative portfolio of first-in-class treatments that target multiple mechanisms of age related diseases including cancer. Our programs are based on cutting-edge research performed by Erasmus University Medical Center Rotterdam, The Netherlands. Through linking a network of clinicians and scientists in internationally leading research institutes and hospitals, Numeric Biotech will drive its portfolio of ground-breaking therapies from laboratory to clinic through various collaborations with leading research institutes and clinics which will give the company a firm basis in the new research paradigm of aging and age related diseases.

Numeric Biotech have a highly experienced and dedicated leadership team with an outstanding track record of discovering and developing innovative medicines. The Numeric Biotech team members all have a longstanding history of successful drug launches and commercial success, both in a smaller biotechnology environment as as well as larger blue chip pharmaceutical companies.


Chronological age represents the single greatest risk factor for human disease. Cellular senescence, which is a permanent state of cell cycle arrest induced by cellular inflammation and stress, has recently emerged as a fundamental component of the mechanism of aging that contributes (by secretion of inflammatory molecules) to diseases of later life, including cancer, atherosclerosis and osteoarthritis.

Numeric Biotech develops therapeutic compounds that selectively eliminate senescent cells (SNC’s). These therapeutic compounds were tested in various ex-vivo and animal models that demonstrated reversal of the underlying disease process, which may have a preventative effect regarding oncogenesis and the inception of chronic degenerative target organ diseases.

Striking pre-clinical in-vivo results were published in peer reviewed scientific journals regarding disease modifying effects in the following indications:

- Treatment refractory forms of Metastatic Melanoma, Breast Cancer and Glioblastoma Multiforme
- Chronic Kidney Disease
- Secondary effects of systemic chemotherapy

Senolytic Pipeline

Numeric Biotech has generated a pipeline of proprietary selective senolytic lead compounds that are able to target and eradicate or cells whose status is undermined by senescent processes. Numeric Biotech is poised to initiate the first of a series of clinical programs by 2019.

Prof Roland Kanaar, PhD

Roland Kanaar studied chemistry at Leiden University and obtained his PhD degree (cum laude) in 1988 for biochemical research on the mechanism of site-specific DNA recombination. His post-doctoral work with at the University of California, Berkeley, aimed at understanding mechanisms of homologous recombination and at understanding how proteins and RNA interact during RNA splicing. In 1995 he joined the Department of Genetics and the Department of Radiation Oncology at Erasmus University Medical Center Rotterdam. In 2000 he was appointed Professor of Molecular Radiation Genetics. His current research addresses the mechanisms and biological relevance of the DNA damage response. The DNA damage response is essential to prevent chromosomal abnormalities, which in their turn may lead to hereditary diseases, cancer, cell decay and aging. Depending on the specific question at hand techniques from biophysics, structural biology, biochemistry, cell biology, molecular biology and animal genetics are applied in his laboratory. Integrating information through this spectrum of techniques has a synergistic effect on the ability of his research group to translate fundamental insight into how the DNA damage response operates to how it can be used to select patients for DNA damage response-targeting precision cancer therapy and how it can be manipulated to design and explore novel cancer treatments. In 2002 he was elected as a member of the European Molecular Biology Organization and in 2013 he was elected to the Royal Netherlands Academy of Arts and Sciences (KNAW). In 2016 he was appointed professor of Molecular Genetics and became head of the department of Molecular Genetics at the Erasmus MC. He serves on a number of advisory boards, including the Permanent Commission Large Scientific Infrastructure from NWO and the Program Board of Holland Proton Therapy Center.

Press Release:

Numeric Biotech receives first investment from UNIIQ for the development of anti-senescence drug compounds

Rotterdam, 25 April 2018 – Numeric Biotech, an Erasmus MC Spinoff company developing compounds against cell senescence, is receiving €300,000 from the UNIIQ investment fund and Erasmus MC. Using this investment, Numeric Biotech can make an important step forward in the development of its lead drug compounds. The investment was announced by Liduina Hammer, Fund Manager UNIIQ and Thijs Spigt, Director Erasmus MC TTO, during the UNIIQ Spring Live event in Leiden.

Senescence and cancer therapy
In the majority of cases, damaged human cells are cleared by the body’s own defence mechanisms. In some cases, however, such cells will remain in the body. These cells, called senescent cells, also play an important role in the aging process of the human body. Numeric Biotech, in collaboration with Erasmus MC, has shown that their lead drug compound is able to clear these senescent cells effectively in mice.

A number of aging diseases might be able to be treated using the technology of Numeric Biotech, but the company will first focus on oncological indications. “We believe that this important technology will contribute to a better understanding of clearing senescent cells from the human body”, says Hans van Berkum, co-founder and CEO of Numeric Biotech, “the support from UNIIQ allows us to further study age-related diseases and in particular the effect of our drug compounds for treatment of certain cancers.”

UNIIQ Proof of Concept investment
“We are very enthusiastic about the opportunities for the technology developed at Numeric Biotech”, says Liduina Hammer, Fund manager at UNIIQ. “The field of senescence is rapidly developing and pre-clinical results have shown great potential for future treatments. We are confident that Numeric Biotech, in collaboration with excellent academic institutions such as Erasmus MC, can further improve patient treatment. UNIIQ focusses on investments with major potential impact and with this investment we have clearly found such potential”.

With the investment by UNIIQ and Erasmus MC, Numeric Biotech will be able to further develop their drug compounds in order to perform additional pre-clinical experiments, necessary for the product to enter clinical trials. Numeric Biotech has a worldwide exclusive license from Erasmus MC covering the substance FOXO4-DRI including a wide range of variations.
