Those affected by primary biliary cholangitis (PBC) are fighting back against the recommendation by the EMA that the marketing authorization for Ocaliva (obeticholic acid), a second-line treatment used by 7,000 patients in Europe, be withdrawn. Earlier today, July 25, patients and their supporters staged a protest outside the European Commission building in Brussels to oppose EMA’s position that Ocaliva’s conditional license should be revoked.

Interim data from two early stage Friedreich’s ataxia (FA) cardiomyopathy studies from Lexeo Therapeutics Inc. hit the mark by reducing heart muscle thickness, a key cause of death among patients with the rare disease. The results came from the Sunrise-FA phase I/II study and an investigator-initiated phase Ia study of LX-2006, an adeno-associated virus-mediated gene therapy encoding the human frataxin gene. The drug is designed to improve frataxin protein expression to improve mitochondrial cell function.

After a previous phase III failure, Savara Inc. kept at it and found success with molgramostim for the rare lung disease autoimmune pulmonary alveolar proteinosis. A second attempt, the pivotal phase III Impala-2 study of molgramostim, an inhaled form of recombinant granulocyte macrophage colony-stimulating factor for adults, hit its primary endpoint and left participants breathing easier. The results led Savara to say it would complete a BLA submission sometime in the first half of 2025, with filings in Europe and Japan to follow.

Focused on oral therapies for obesity, diabetes and rare diseases, Boston-based Syntis Bio Inc., which raised $15.5 million through seed funding last year, emerged from stealth to advance its synthetic tissue-lining technology and a pipeline of candidates.

In a deal worth up to $1.8 billion, Biogen Inc. is buying Human Immunology Biosciences Inc. (Hibio), bolstering its late-stage immune-disease treatment portfolio and diversifying its pipeline. The massive amount comprises $1.15 billion up front and as much as $650 in potential milestone payments. The deal in rare diseases brings Biogen phase III-ready felzartamab, a fully human monoclonal antibody that selectively depletes CD38-positive plasma cells and natural killer cells. Hibio also is developing izastobart, an anti-C5aR1 antibody. Both assets were in-licensed from Morphosys AG in June 2022. Hibio also has mast cell programs in the discovery stage.

With no drugs approved by the U.S. FDA for treating Becker muscular dystrophy, Edgewise Therapeutics Inc. reported positive two-year, phase Ib data looking at patients’ ability to physically function, plus biomarker data.

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.

Voydeya (danicopan), from Alexion, Astrazeneca Rare Disease, racked up its second global approval as the U.S. FDA greenlit it as an add-on therapy for treating extravascular hemolysis in adults with paroxysmal nocturnal hemoglobinuria (PNH), a crowded market with several already approved treatments and more in development.
