Positive phase III data from Cymabay Therapeutics Inc. with seladelpar, the peroxisome proliferator-activated receptor for primary biliary cholangitis (PBC), could mean trouble for Intercept Pharmaceuticals Inc.’s second-line therapy, the farnesoid X receptor agonist Ocaliva (obeticholic acid), which Cymabay aims to replace with its compound as the preferred choice.

Brii Biosciences Ltd.’s therapeutic vaccine for hepatitis B (HBV), BRII-179 (VBI-2601), induced functional immune responses – inducing broad antibody and T-cell responses – in patients with chronic HBV in a phase II trial that evaluated the vaccine in combination with pegylated interferon-alfa, according to interim results.

While an “unexpected placebo effect” marred its primary endpoint, the pivotal phase II/III study testing AMO-02 (tideglusib) showed clinically significant benefits across a range of functional and objective assessments, according to developer Amo Pharma Ltd., which is prepping to meet with regulators to discuss potential approval for use in children and adolescents with congenital myotonic dystrophy type 1 (CDM1), an ultra-rare subtype of myotonic dystrophy type 1 for which no treatment options are available.

Wall Street’s hoped-for phase III derisking event from Insmed Inc. materialized, and shares of the firm (NASDAQ:INSM) closed Sept. 5 at $26.37, up $3.73, or 16.5%, on positive top-line results from the study called Arise with inhaled Arikayce (amikacin) in patients with newly diagnosed or recurrent nontuberculous mycobacterial lung infection by Mycobacterium avium complex (MAC) who had not started antibiotics. “We crushed it” on culture conversion with Arikayce, CEO William Lewis said. “We could not be happier about the results of this study. It exceeded all of our expectations on every front.”

For many multiple sclerosis patients, the approval over the past 30 years of a lengthy list of immunomodulatory therapies has helped to reduce the frequency of relapses and to slow disease progression. However, there has been little parallel progress in the development of remyelination therapies, to tackle the other key pathophysiological dimension of the disease. Patients still have no therapies that can help to repair at least some of the damage that results from flare-ups, and the resulting neuronal loss contributes to further disease progression and disability. Rewind Therapeutics NV, of Leuven, Belgium, is one of a small clutch of firms attempting to tackle this problem.

Blood biomarkers have been found in patients hospitalized with acute COVID-19 that are predictive of the cognitive defects of long COVID. Post COVID-19 deficits in cognition, including brain fog, are common and debilitating. They are also clinically complex, with both objective and subjective components. In the U.K., one in eight patients received their first ever neurological or psychiatric diagnosis within six months following COVID-19.
