Relacorilant, a cortisol modulator from Corcept Therapeutics Inc., produced new and strong phase III results in treating platinum-resistant ovarian cancer. The company also has relacorilant in studies that could eventually lead to approval in other indications. In the near term, though, the positive data led to the company’s stock (NASDAQ:CORT) closing 109% higher at $114.22 per share on March 31.
For once, the EMA appears to have pipped the U.S. FDA to the post, with Pfizer Inc.’s hemophilia A and B therapy Hympavzi (marstacimab) recommended for approval in Europe on Sept. 20, while the U.S. PDUFA date is set for the fourth quarter of the year.
Pharma-biotech pairings continued apace in the antibody-drug conjugate (ADC) space, with 2023 capped by Legochem Biosciences Inc. signing a $1.7 billion licensure deal with Johnson & Johnson arm Janssen Biotech Inc. for the former’s Trop2-directed compound, the second-biggest Korean technology transfer agreement.
Buying out Immunogen Inc. in a whopper cash deal valued at about $10.1 billion, Abbvie Inc. has major plans for an expanded label on the antibody-drug conjugate Elahere (mirvetuximab soravtansine-gynx), already approved for treating platinum-resistant ovarian cancer.
Immunogen Inc. scored a major win in top-line data from the confirmatory phase III trial called Mirasol evaluating the approved antibody-drug conjugate Elahere (mirvetuximab soravtansine-gynx, “mirv”) vs. chemotherapy in patients with folate receptor alpha-positive platinum-resistant ovarian cancer (PROC). The victory led shares of the Waltham, Mass.-based firm to close May 3 at $12.26, a rise of $7.06, or 135%.
The accelerated approval by the U.S. FDA of Immunogen Inc.’s landmark antibody-drug conjugate Elahere (mirvetuximab soravtansine-gynx) injected further oomph into the NaPi2b space, where a handful of developers are due to yield important data shortly. In play are such names as Mersana Therapeutics Inc. and Zymeworks Inc., encouraged by historical – if not entirely successful – efforts by giant Roche Holding AG.
In the wake of ongoing criticism over the U.S. FDA’s 2021 accelerated approval of Biogen Inc.’s Alzheimer’s drug, Aduhelm, the percentage of novel drugs receiving accelerated approval last year was the lowest it’s been since 2018.
