Study Summary
This trial is the first step in testing the hypothesis that adding Photobac® Photodynamic Therapy to surgical removal of a glioblastoma or gliosarcoma will be both safe and effective.
Who is the study for?
This trial is for adults over 18 with recurrent brain tumors (glioblastoma or gliosarcoma) that can be surgically removed. They must have completed standard therapy, have good organ function and blood counts, not be on anticoagulants, agree to use contraception if of child-bearing potential, and understand the study's investigational nature.Check my eligibility
What is being tested?
The trial tests Photodynamic Therapy (PDT) using Photobac® as an add-on to surgery in treating brain tumors. PDT involves a special drug activated by light aimed at improving safety and effectiveness compared to current treatments.See study design
What are the potential side effects?
Potential side effects include temporary skin photosensitivity due to the photosensitizer used in PDT. Other risks may relate to typical surgical procedures such as bleeding or infection.

Treatment Details
Study Objectives
Outcome measures can provide a clearer picture of what you can expect from a treatment.Primary outcome measures
Measure Photobac® concentration in tumor tissue removed during resection and in the bed of the tumor both before and after ligh treatment.
Measure the Photobac concentration in blood.
Overall survival from time of diagnosis
+3 moreSecondary outcome measures
Assess patterns of treatment failure for any association with the drug dose
Duration and severity of skin photosensitivity t osimulated sunlight .
Measure Stat 3 Crosslinking as a quantitative marker of singlet oxygen tissue damage

Experimental Treatment
Group I: Photochemotherapy as an adjuvant to surgical resection of glioblastomaExperimental Treatment1 Intervention
3-(1-Butyloxy)ethyl-3-deacetyl-bacteriopurpurin-18-n-butylimide methyl ester (Photobac®) is injected 24 hours prior to surgical resection of a recurrent Glioblastoma or gliosarcoma. Immediately following the resection the cavity is treated with 50 joules/ square cm of 787 nm light .The drug dose is escalated using three patient cohorts until a dose limiting toxicity is reached or the upper limit of the 8 step escalation is reached.
