Investors warmed to biopharma company equities, particularly in the final quarter of the year, with the BioWorld Biopharmaceutical Index increasing 23% in value during this period, helping the group climb to a respectable 14% for the year after being underwater from April through to September.
With a 349% increase in stock price since its June debut on U.S. markets, Boston-based Karuna Therapeutics Inc. secures the title of best IPO performer so far in 2019. The stock skyrocketed in November following positive top-line phase II data of Karxt in acute psychosis in patients with schizophrenia, providing a potential read-through to larger indications such as Alzheimer’s disease and pain.
Pairing the in-licensed muscarinic acetylcholine receptor agonist xanomeline with the well-known muscarinic antagonist trospium chloride in the single drug called Karxt gave Karuna Therapeutics Inc. the required phase II efficacy against acute psychosis in schizophrenia, while keeping a quite satisfactory safety and side-effect profile.
