About Mereo

Mereo is a UK-based biopharmaceutical company focused on the development of innovative medicines that aim to address unmet medical needs in rare and specialty disease areas and improve patient quality of life. The Company seeks to selectively acquire development-stage product candidates with demonstrated clinically meaningful data from large pharmaceutical companies and to rapidly progress these product candidates to subsequent value inflection points.

Mereo combines the operational discipline and efficiency of a small company with the financial resources to conduct comprehensive clinical studies. The Company has the option to directly commercialise products, for example in orphan diseases, in addition to partnering or divesting its products.

Mereo's initial portfolio consists of three mid-late stage clinical assets that were acquired from Novartis in July 2015. BPS-804 is being developed for the prevention of fractures resulting from osteogenesis imperfecta (brittle bone disease); BCT-197, is being developed to treat inflammation in patients with an acute exacerbation of chronic obstructive pulmonary disease; and BGS-649 is a once-weekly pill to restore normal testosterone levels in men with hypogonadal hypogonadism.

In H1 2016 the Company initiated a Phase 2 study with BCT-197 and a Phase 2b study with BGS-649. Mereo intends to commence a Phase 2b/3 study during H2 2016 for BPS-804. Additional product opportunities (from a range of large pharmaceutical companies) are under active evaluation.
