Ionis Pharmaceuticals Inc. and Astrazeneca plc, partners on the antisense oligonucleotide inhibitor eplontersen, said interim phase III data showed the candidate had a positive impact on disease progression in patients with hereditary transthyretin-mediated amyloid polyneuropathy, giving them confidence to plan for a U.S. FDA NDA filing in the indication before the end of 2022.
In this case, more is just too much. The number of participants needed to determine a significant clinical outcome in 9 Meters Biopharma Inc.’s phase III of larazotide in treating celiac disease has grown too large to support the study. The company said an independent statistician’s interim analysis convinced it to take a step back and re-evaluate its options for developing the zonulin inhibitor in the indication.
After an up-and-down day – mostly up, toward the end – during which the phrase “totality of the data” got air time aplenty, shares of PTC Therapeutics Inc.

From 20 years of research on metabolic change as a result of salt intake, Karen Duggan discovered in 2003 that a naturally occurring molecule in the human body, native vasoactive intestinal peptide (VIP), was capable of reversing fibrosis caused by hypertension and other chronic diseases such as diabetes. From that discovery, Vectus Biosystems Ltd. was founded, and the company has developed a new class of mimetic drug candidates and a drug library based on VIP.
Alzheimer’s experts have suggested that future research may involve combination therapies after yet another trial failure involving a drug targeting amyloid – in this case Roche Holding AG’s crenezumab. Originally discovered by Swiss biotech AC Immune SA, of Lausanne, crenezumab failed to slow or prevent cognitive decline in people with a certain mutation that causes early onset in a closely watched trial.
A day after announcing it would pump $120 million into a Michigan manufacturing facility for Paxlovid (nirmatrelvir/ritonavir), Pfizer Inc. produced new data it plans to use in an U.S. NDA submission for treating COVID-19.
