Develops setrusumab for osteogenesis imperfecta and alvelestat for severe alpha-1 antitrypsin deficiency-associated lung disease. Clinically advanced assets are acquired and advanced through partnerships, with setrusumab commercial rights retained in Europe and the U.K.
Develops setrusumab for osteogenesis imperfecta and alvelestat for severe alpha-1 antitrypsin deficiency-associated lung disease. Both programs reflect an asset-selection model: clinically advanced candidates are acquired after larger drugmakers deprioritize them, then advanced through scientific, commercial, and collaboration capabilities.
Setrusumab is partnered with Ultragenyx, while commercial rights in Europe and the U.K. are retained. Other candidates came from Novartis, AstraZeneca, and the OncoMed transaction, leaving a portfolio of partnered or partner-seeking programs rather than a discovery-led platform.
Clinical-trial enrollment, potential product-market size, key executives, and continued Nasdaq listing compliance shape execution. Certain pre-commercial and manufacturing activities for setrusumab were curtailed or delayed after top-line trial data.
