About

This is a randomised, open-label, multi-centre, Phase II study in patients with newly diagnosed glioblastoma.

62 patients with newly diagnosed glioblastoma are enrolled in the study in a 1:2 allocation (standard of care (SOC): ALECSAT as an adjunct therapy to SOC).

Patients recruited into this study will receive either:

• ALECSAT as an adjunct therapy to standard of care for newly diagnosed glioblastoma (first line therapy: Stupp regimen, followed by second line therapy at the Investigator's discretion) or
• Standard of care therapy for newly diagnosed glioblastoma (first line therapy: Stupp regimen, followed by second line therapy at the Investigator's discretion).

Enrollment: 62 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers

• Patients from high incidence areas for Human T-Lymphotropic Virus (HTLV-1) virus or who has a parent or spouse from a high incidence area must be excluded unless tested negative for HTLV-1 virus.
• Known allergy to study medication.
• Any condition or illness that, in the opinion of the Investigator or medical monitor, would compromise patient safety or interfere with the evaluation of the safety of the investigational drug.
• Any concurrent illness that may worsen or cause complications in connection with blood donation, for example uncontrolled epilepsy, cardiovascular, cerebrovascular or respiratory disease.
• Use of immunosuppressant drugs with the exception of steroids. Blood transfusion within 48 hours prior to the donation of blood for ALECSAT production.
