After decades of trying and dozens of failed trials, amyloid targeting has paid off with the first disease-modifying agents reaching the market. But success does not mean slam dunk. Aduhelm (aducanumab, Biogen Inc.) was dogged by controversy throughout its brief tenure, and Biogen pulled the plug on it in early 2024. Leqembi (lecanemab, Biogen Inc.) has received full approval. In this second installment of a three-part series on Alzheimer’s, BioWorld looks at the nuanced view of amyloid’s role in the disease.

With a $128 million series A financing, Diagonal Therapeutics Inc. launched to develop its lead program using agonist antibodies for treating, among other indications, the rare disease hereditary hemorrhagic telangiectasia. The antibodies are designed to activate a receptor complex in the TGF-β superfamily genetically impaired in patients with the bleeding disorder. Diagonal also is developing a treatment for the orphan disease pulmonary arterial hypertension.

Investors might not have been overly excited, but Genmab A/S executives enthused about the “complementarity” of its proposed acquisition of antibody-drug conjugate (ADC) specialist Profoundbio Inc. for $1.8 billion in cash. The deal, expected to close in the first half of 2024, marks the biggest by far for the Copenhagen, Denmark-based biopharma and the latest transaction for the red hot ADC space.
