Phase IIa Safety and Light Dose-escalation Study in Patients With Primary or Recurrent/High-grade Glioma Using the Litx™ System to Confirm the Zone of Tumor Destruction During the Intraoperative Treatment of Glioma

Study Purpose

The pupose of this study is to demonstrate the safety of the Litx™ therapy and confirm the zone of tumor destruction with escalated light doses following intraoperative treatment of primary or recurrent glioma.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

- Have a known sensitivity to porphyrin-type drugs or known history of porphyria

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT00409214
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Light Infusion Technology (Litx™) is a locoregional cancer treatment in which a systemically administered light-activated drug (LS11) is activated locally by illuminating the diseased tissue using light-emitting diodes (LEDs) of a specific wavelength. The activated photosensitizer reacts with endogenous oxygen to yield highly reactive species of oxygen that cause destruction of cellular structures such as mitochondria, lysosomes and cell walls leading to irreversible cell damage and tissue death. Either twenty-four or twelve hours prior to surgery, the patient will receive an intravenous dose of 1 mg/kg of LS11, given IV by slow push over 3-5 minutes. Following craniotomy, patients will undergo intraoperative placement of a single Light Source, centrally placed within the tumor, under direct visualization prior to tumor resection. Following placement of the light source (with the depth of the end of the light bar from the cortical surface to be calculated from the pre-operative MRI and spiral CT scan, so as to be centralized within the main tumor bulk), light will be delivered following a predetermined escalation schedule (either 100 J/cm or 200 J/cm) at 20 mW/cm light energy for a treatment time of 1 hour 24 minutes (100J/cm) or 2 hours 46 minutes (200 J/cm). The Light Source will then be manually removed and the tumor maximally resected. The resected tumor and marginal tissue will be submitted for pathology to determine depth of cell death, extent of tumor tissue containing closed vessels, any evidence of vessel closure or other damage to tissues outside of the projected kill zone.
