Schlieren (Zurich), Switzerland, November 29, 2019 – Kuros Biosciences (SIX: KURN) (the Company or Kuros) has obtained on November 28, 2019 after market close a binding order from Optiverder B.V., beneficially owned by Mr. C.A.C.M. Oomen, Delft, The Netherlands (the “Investor“) for 2,818,718 Offered Shares at the subscription price of CHF 1.95 per Offered Share for an aggregate amount of CHF 5,496,500.10 (the “Investment“) for the Share Offering. With this binding order, the Minimum Gross Proceeds of CHF 4 million required to complete the Offering have already been surpassed irrespective of the amount of Offered Shares that will be subscribed in the Rights Offering by existing shareholders during the Rights Exercise Period, which will end on December 2, 2019, 12:00 noon (CET).

The Company has decided to preferably allocate Offered Shares in the Share Offering to the Investor due to the Investor’s early binding order, the size of its order and the signing of a lock-up of 90 days after the First Day of Trading by the Investor. The Company has further decided to fully allocate the Offered Shares required for the covering of the full Investment to the extent the number of Offered Shares available in the Share Offering is sufficient.

The exact number of Offered Shares sold in the Rights Offering will be published in the electronic media and by press release on December 2, 2019 after close of trading. The Company expects to publish the final number of Offered Shares sold in the Offering by a media release and in the Supplement on or around December 4, 2019. It is expected that the trading in the Offered Shares on the SIX Swiss Exchange will commence on December 6, 2019.

Capitalized terms used in this press release have the meaning given to such terms in the offering and listing prospectus published by the Company on November 20, 2019.

About MagnetOs

MagnetOs bone graft has an advanced submicron surface topography that leads to the formation of bone, rather than scar tissue, following implantation. In preclinical models, MagnetOs preferentially directs early wound healing toward the bone-forming pathway, meaning that bone can be formed even in soft tissues without the need for added cells or growth factors, resulting in an osteoinductive claim in Europe. MagnetOs promotes local bone formation equivalent to current gold standard, autograft. A substantial number of clinically relevant and predictive studies have demonstrated its equivalence to the current gold standard (patient’s own bone, which may not be available in sufficient quantities and/or involves morbidity, costs and pain associated with its harvesting from another healthy site of the patient’s body). MagnetOs is now supported by over two years’ clinical experience since its launch in the United Kingdom in May 2017. For more information, see: www.magnetosbonegraft.com

About Fibrin-PTH (KUR-113)

Fibrin-PTH (KUR-113) consists of a natural fibrin-based healing matrix with an immobilized targeted bone growth factor (truncated human parathyroid hormone (PTH) analog). Fibrin-PTH (KUR-113) is designed to be applied directly into and around an intervertebral body fusion device as a gel, where it polymerizes in situ. Fibrin-PTH (KUR-113) functions via the well-established mechanism of action of parathyroid hormone; has been demonstrated in animal models of spinal fusion to be comparable to rhBMP-2; and has been shown in preclinical studies to be easy to use and ideal for open or minimally invasive techniques. Fibrin PTH (KUR-113) is an investigational drug/biologic combination product candidate. Fibrin PTH (KUR-113) has been evaluated in animals for use in lumbar interbody fusion. The safety & efficacy of Fibrin PTH (KUR-113) has not yet been evaluated for spinal fusion in humans.
