After Keros Therapeutics Inc.’s voluntary halt of dosing in two arms of its phase II study in pulmonary arterial hypertension, the company’s stock crumpled after a year of muscular performance and its recent and massive deal with Takeda Pharmaceutical Co. Ltd.

Sound Pharmaceuticals Inc.’s lead candidate, the anti-inflammatory SPI-1005 (ebselen), has produced positive pivotal phase III study data in treating Meniere’s disease, an inner-ear disorder that can lead to vertigo and deafness.

The U.S. FDA has greenlit the first steps of Uniqure NV’s accelerated approval pathway for gene therapy AMT-130 to treat Huntington’s disease. The agency said data from the ongoing phase I/II studies compared to natural history external control are muscular enough to get the process going without having to dive into additional studies.

Poseida Therapeutics Inc. is being bought out for $1.5 billion by partner Roche Holdings Inc. to develop allogeneic CAR T therapies to treat hematologic malignancies. The two companies began their collaboration in August 2022, a deal that brought Poseida $110 million up front and another $110 million in near-term milestone payments. With the acquisition, Roche plans to develop CAR T programs for solid tumors and autoimmune diseases with Poseida's genetic engineering platform and preclinical programs.

With the U.S. FDA approval of Attruby (acoramidis) for transthyretin amyloidosis with cardiomyopathy (ATTR-CM), Bridgebio Pharma Inc. is taking on an industry giant. The next-generation, oral, small-molecule stabilizer of transthyretin will take on Pfizer Inc.’s Vyndamax (tafamidis, Vyndaqel), a TTR stabilizer approved in 2019 for ATTR-CM but expected to lose exclusivity in late 2028. The approval was based on a phase III study that showed Attruby significantly reduced death and cardiovascular-related hospitalizations. The NDA, which had a Nov. 29 PDUFA date, was approved Nov. 22.

More than a week ahead of its priority PDUFA date, the U.S. FDA has greenlit the first dual HER2-targeted bispecific antibody specifically for previously treated, unresectable or metastatic HER2-positive biliary tract cancer. The approval went to Jazz Pharmaceuticals plc for Ziihera (zanidatamab), an injection given to adults every two weeks. The treatment was designed to have a more favorable profile than competitors, where drugs targeting HER2 such as Astrazeneca plc’s Enhertu (trastuzumab deruxtecan) and Roche Holding AG’s Herceptin (trastuzumab) are options, as well as checkpoint inhibitors such as Merck & Co Inc.’s Keytruda (pembrolizumab).

Biosion Inc. is getting more than $40 million in cash up front from Aclaris Therapeutics Inc. for the rights to develop two antibodies. The regulatory and sales milestones could also bring Biosion another $900 million. The two assets are BSI-045B, a high affinity and high potency anti-TSLP monoclonal antibody, and BSI-502, a bispecific antibody directed against TSLP and IL4R.

Flare Therapeutics Inc. will receive $70 million in cash up front from Roche Holding AG, and the deal could ultimately bring the company about $1.8 billion plus royalties. Flare will search for small molecules that can be used to treat undruggable transcription factors to treat cancer. Also, Novartis AG will pay computational-chemistry expert Schrödinger Inc. $150 million up front and as much as $2.3 billion in milestones to develop several candidates along with up to $892 million in R&D and milestone payments.
