Schlieren (Zurich), Switzerland, March 18, 2021 – Kuros Biosciences closed the year with outstanding results for 2020, accelerating sales by 58% and initiating the Phase II study for Fibrin PTH, confirming its successful transition into a fully-fledged orthobiologics company with scientific, clinical, and commercial excellence in bone regeneration.

Kuros raised gross proceeds of CHF 18.6 million from a capital increase to advance its pipeline, in particular the Phase II clinical study of its proprietary Fibrin-PTH product candidate in spinal fusion, and to progress commercialization of MagnetOs in the U.S. and selected geographies in Europe.

Despite the worldwide pandemic, Kuros achieved strong sales growth of MagnetOs in the U.S. and launched MagnetOs in selected European countries.

Joost de Bruijn, Chief Executive Officer, said: “The Kuros team has delivered an outstanding performance in a complex environment, making significant progress on all fronts in 2020. The impressive sales growth of MagnetOs is a turning point in the history of the company and confirms our transformation into commercial company. Beyond this, we have started the Phase II with Fibrin-PTH in spinal fusion, which represents a huge commercial opportunity.”

Financial position

Cash and cash equivalents (including trade and other receivables) as of December 31, 2020, amounted to CHF 29.8 million, compared to CHF 21.9 million as of December 31, 2019.

Net operating costs increased to CHF 13.4 million (2019: CHF 11.7 million) primarily due to higher Marketing and Sales costs of CHF 4.3 million (2019: CHF 2.3 million) which contained costs for personnel and other costs for sales and marketing. Expenses for research and development decreased slightly to CHF 4.0 million (2019: CHF 4.7 million), which are mainly external costs for the Phase II study (spine indication) of Fibrin-PTH, as well as personnel costs. General and administrative costs increased slightly to CHF 5.4 million (2019: CHF 5.0 million). Other income amounted to CHF 0.3 million (2019: CHF 0.3 million) and mainly consisted of patent recharges to Checkmate.

Revenues amounted to CHF 4.0 million (2019: CHF 2.6 million) and originated from product sales.
