Study summary

This is a randomized, double-blinded, Phase 2 trial in patients with PML due to JCPyV. Patients will receive treatment with a matched virus-specific T-cell product (CE VST01-JC) or placebo, and will then be monitored for response to therapy.

Read the detailed description

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system caused by JC polyomavirus (JCPyV) occurring in immunocompromised patients who face a disease that is usually progressive and often fatal (Padgett 1971; Tan 2010). Annually, it is estimated that 4,000 people develop PML in the United States and Europe combined (NORD 2015).

This is a randomized, double- blinded, Phase 2 trial in patients with PML due to JCPyV. Patients will receive treatment with a matched virus-specific T-cell product (CE VST01-JC) or placebo, and will then be monitored for response to therapy. The study is designed to evaluate whether CE-VST01-JC infusions will slow and ultimately halt neurological progression in patients with PML compared with placebo as evaluated by modified Rankin Score (mRS).

Eligibility criteria

  • Male or female subjects aged 18 years or older, with actively progressing PML confirmed by MRI and JCPyV present in CSF or in brain tissue (diagnosis confirmed according to algorithm diagnostic criteria for PML developed by the American Academy of Neurology).
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
