With phase III data due from Karuna Therapeutics Inc. with its combo Karxt therapy for schizophrenia, interest is rising in the historically difficult space. Karxt pairs xanomeline, a muscarinic receptor agonist that preferentially stimulates M1 and M4 muscarinic receptors, with trospium, an approved muscarinic receptor antagonist that does not measurably cross the blood-brain barrier, confining its effects to peripheral tissues.
Shares of Intra-Cellular Therapies Inc. (NASDAQ:ITCI) climbed 72.8% to $31.86 on Sept. 9 following news that its FDA-approved schizophrenia drug, Caplyta (lumateperone), could also help improve bipolar depression.
Four new U.S. drug approvals, one accelerated for need, have handed a string of year-end victories to five drugmakers, marking an unusually active start to a week full of global holiday celebrations. Daiichi Sankyo Co. Ltd., Astrazeneca plc, Eisai Inc., Intra-Cellular Therapies Inc. and Allergan plc all secured new approvals from the agency. Daiichi's Enhertu (trastuzumab deruxtecan), the subject of a $6.9 billion deal with Astrazeneca, won accelerated approval for the third-line treatment of adults with unresectable or metastatic HER2-positive breast cancer. Eisai's Dayvigo (lemborexant) was approved to treat insomnia. Intra-Cellular's Caplyta (lumateperone) was approved to treat schizophrenia. Allergan’s Ubrelvy (ubrogepant) became the first of a relatively new class of drugs to be approved for the acute treatment of migraine.
Positive data from one clinical trial evaluating lumateperone in patients with bipolar disorder wasn't enough to lift Intra-Cellular Therapies Inc.'s stock Monday as another trial's failure with the same drug severely dampened the price of shares, while analysts took the long, more optimistic view.
