Diagonal Therapeutics Inc.’s DIAG-723 has been awarded orphan drug designation by the FDA for the treatment of hereditary hemorrhagic telangiectasia (HHT). Additionally, the EMA has provided a positive opinion for orphan drug designation, confirming that DIAG-723 meets the criteria for designation as an orphan drug in the E.U.

News from Tectonic Therapeutic Inc. in January took away some of Wall Street’s jitters about the relaxin pathway brought about by Eli Lilly and Co.’s recent moves, but another big pharma player – Astrazeneca plc – is still providing suspense in pulmonary hypertension in heart failure with preserved ejection fraction.

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.
