ANX005, a humanized monoclonal antibody, is designed to inhibit the classical complement pathway which has been associated with Huntington’s disease (HD). In this touchNEUROLOGY interview, we speak with Dr Rajeev Kumar (Rocky Mountain Movement Disorders Center, Englewood, CO, USA) to discuss the role of complement activation in people living with HD and why ANX005 is being used to modify HD.

The abstract entitled ‘Phase 2 study evaluating safety, PK/PD, biomarkers, and efficacy of ANX005 in patients with Huntington’s disease (HD)’ was presented at the International Congress of Parkinson’s Disease and Movement Disorders® in Madrid, Spain, 15 – 18 September 2022.

Questions:

  1. What is currently understood about the role of complement activation in people with Huntington’s disease? (0:24)
  2. What is the rationale behind using a humanized monoclonal antibody to inhibit the complement pathway in order to modify Huntington’s disease? (1:24)
