Vaxcyte Inc. characterized its latest phase II data with VAX-24 as positive but Wall Street wasn’t so sure about the dose-finding outcomes with the 24-valent pneumococcal conjugate vaccine (PCV), and shares of the San Carlos, Calif.-based firm (NASDAQ:PCVX) closed March 31 at $37.76, down $31.70, or 46%.
Bispecific antibodies have gotten plenty of press in recent years, but less prominent in headlines are bifunctional ones – i.e., those that boast one binding site for an antigen and another site for a non-antibody molecule such as a toxin or drug, taking aim at a single target and bringing a secondary function for extra oomph.
Equillium Inc. is forging ahead with regulatory plans for itolizumab in first-line treatment of patients with acute graft-vs.-host disease (GVHD), despite a phase III disappointment. Shares of the La Jolla, Calif.-based firm (NASDAQ:EQ) closed March 27 at 46 cents, down 29 cents, or 39%, on top-line data from the Equator study testing itolizumab, which is designed to target the CD6-ALCAM signaling pathway.
Wave Life Sciences Ltd. plans to file with the U.S. FDA for accelerated approval of WVE-N531, an exon skipping oligonucleotide for boys with Duchenne muscular dystrophy (DMD) who are amenable to exon 53 skipping, a decision based on favorable data from the phase II Forward-53 study. The analysis was conducted after 48 weeks of treatment with 10 mg/kg of the drug dosed every two weeks. Forward-53 achieved all trial goals, turning up sustained exon skipping, muscle concentrations, and dystrophin restoration through 48 weeks and a 61-day tissue half-life that supports giving the DMD therapy once a month.
Roivant Sciences Ltd. CEO Matt Cline said the firm’s unit Immunovant Inc. with FcRn blocker batoclimab has established “frankly a new bar” in myasthenia gravis (MG) as the New York-based firm reported top-line results from its phase III study and first data from period 1 of the phase IIb study with the same drug in chronic inflammatory demyelinating polyneuropathy. The data look promising, and Immunovant intends to use the findings to help advance second-generation FcRn prospect IMVT-1402 in both indications. Potentially registrational trials are planned. The U.S. FDA has granted IND clearance.
Wall Street was weighing the gravity of the death from acute liver failure of a patient who was treated for Duchenne muscular dystrophy (DMD) with Sarepta Therapeutics Inc.’s gene therapy, Elevidys (delandistrogene moxeparvovec). Liver injury is a known possible side effect of the product, first approved by the U.S. FDA in June 2023 for DMD, as well as other AAV-mediated gene therapies, and the potential problem is highlighted in Elevidys’ prescribing information.
Investors wanted more from Incyte Corp.’s top-line results in hidradenitis suppurativa (HS) from its pivotal phase III Stop-HS trial program with oral small-molecule JAK1 inhibitor povorcitinib in adults with moderate to severe disease. Shares of the Wilmington, Del.-based firm (NASDAQ:INCY) closed March 17 at $62.01, down $5.85, after the company made public that Stop-HS1 and Stop-HS2 met the primary endpoint at both tested doses (45 mg and 75 mg)
U.S. President Donald Trump touched off a not-uncommon flurry of puzzlement and outrage when, during his speech to Congress on March 4, he referred to an example of government waste as spending $8 million on “making mice transgender. This is real.” Skeptical media outlets jumped on the case right away.
