Clinical Trials

A clinical trial evaluating the safety, tolerability and pharmacokinetics of ABBV-CLS-7262, an investigational drug, in people with Vanishing White Matter has been initiated and posted on ClinicalTrials.gov, the U.S. NIH registry of clinical trials “Phase 1b Study to Investigate ABBV-CLS-7262’s Safety, Tolerability & Pharmacokinetics in Vanishing White Matter Patients.” ABBV-CLS-7262 is being developed by Calico Life Sciences (Calico) in collaboration with AbbVie. Calico will continue to partner with the VWM Consortium on researching ABBV-CLS-7262 for VWM disease and will provide periodic updates on the status of this clinical research via the News & Updates section of the VWM Consortium website.

The Amsterdam Leukodystrophy Center at the Amsterdam University Medical Centers (Amsterdam UMC) is conducting a clinical trial in children with Vanishing White Matter (VWM). In this trial, they want to evaluate whether a drug called Guanabenz is effective in slowing progression, stabilizing, or even improving the brain white matter abnormalities in VWM. Guanabenz is an old and well-known medicine that has been used for decades for the treatment of high blood pressure. It has been approved by the FDA, the American medicines agency.
