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.
The BioWorld Cancer Index (BCI) saw its highest point of the year from April through July, when it had a run above 30%, before falling to 23.5% at the end of August. It closed Q3 up 22.96% for the year, a sharp divergence from the more extensive Nasdaq Biotechnology Index and Dow Jones Industrial Average, which are tracking down 6.16% and up 1.09%, respectively.
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.
Wall Street was not as pleased as some might have expected by Immunogen Inc.’s full results from the pivotal study called Soraya testing mirvetuximab soravtansine (mirv) monotherapy in patients with folate receptor (FR) alpha-high, platinum-resistant ovarian cancer (PROC) who have been previously treated with Avastin (bevacizumab, Roche Holding AG). Analysts hailed the results as positive but shares (NASDAQ:IMGN) closed at $4.30, down 96 cents, or 18.25%.
Despite three mammoth deals signed for antibody-drug conjugates, the BioWorld Cancer Index (BCI), which ended last year down 36%, has fallen another 35% in the early months of 2022. It is a much sharper decline than that seen with the Nasdaq Biotechnology Index and the Dow Jones Industrial Average, which are down 18% and 7.5%, respectively.
LONDON – Antibody-drug conjugate specialist Heidelberg Pharma AG has secured a route into Asia and a fresh injection of much-needed capital, in a licensing and equity deal with Huadong Medicine Co. Ltd. worth up to €930 million (US$1.1 billion).
