Regulation of advanced therapies has come under scrutiny at a conference in London, as activity in the sector heats up amid Europe’s root and branch review of pharmaceutical legislation.

Factor XIa inhibitors milvexian and asundexian, hailed as the next-generation class of anticoagulants, earned mixed reviews on phase II data presented during the European Society of Cardiology Congress 2022. However, developers Bristol Myers Squibb Co./Janssen Pharmaceutical Co. and Bayer AG, respectively, are moving into late-stage testing, citing clear mechanisms of action that put the FXIa drugs at least on par with approved factor Xa drugs in terms of efficacy while offering potentially better safety profiles that could give physicians an option for patients with stroke or atrial fibrillation who are currently undertreated with anticoagulants due to bleeding risks.

Likely to garner attention at the upcoming European Society of Medical Oncology meeting are the MAGE-A4 and PRAME antigens which, although well-known and validated, have proved evasive for drug developers – a situation that may soon change.

Beta-site APP-cleaving enzyme 1 (BACE1) inhibitors have a long history of failure in patients with Alzheimer’s disease. Clinical development of verubecestat, elenbecestat, lanabecestat, umibecestat, atabecestat and LY-3202626 were all discontinued. The drugs largely showed that inhibiting BACE1 reduced amyloid beta (AB) in both cerebrospinal fluid and plasma, reduced AB plaques on PET scans and reduced phosphorylated tau. Unfortunately, patients had early cognitive worsening, and there were signs of lowering of brain volume and increases in psychiatric adverse events.
