Prospective Evaluation of AI R&D Tool in Adult Glioma and Other Primary Brain Tumours (PEAR-GLIO)

Study Purpose

Pear Bio has developed a 3D microtumor assay and computer vision pipeline through which the response of an individual patient's tumor to different anti-cancer regimens can be tested simultaneously ex vivo. This study will recruit patients with primary brain tumors who are due to undergo surgery. Oncologists will be blinded to treatment response on the Pear Bio tool (the assay will be run in parallel with the patient's treatment). The primary objective of this study is to establish the ex vivo model and confirm whether approved therapies exhibit their intended mechanism of action in the model. Secondary objectives include correlating test results to patient outcomes, where available.

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.	Observational
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion: 1. Patient diagnosed with operable brain cancer, thought likely to be primary solid brain tumor on imaging (grade 2

- 3 meningioma; grade 1 - 4 tumors otherwise) or with histologically proven primary malignant solid brain tumor.

2. Able to give written informed consent prior to admission to this study; 3. Female or male aged ≥18 years; 4. Patient consents to the use of their surgical sample and 40mL of whole blood for research purposes. 5. Surgical sample and yields ≥0.4g for the study. 6. Patient consents to providing histopathology data (e.g., confirmation of histological subtype as oligodendroglioma) and other pseudonymised health information including imaging, treatment and outcome data. Exclusion: 1. Inoperable or biopsy only. 2. Suspected lymphoma or myeloma, or grade 1 meningioma. 3. Preoperative haemoglobin levels below 120g/L. 4. Patients who have already received chemotherapy, targeted therapy, immunotherapy, or radiotherapy less than 30 days before date of surgery, unless as part of a clinical trial (requires per-patient sponsor approval) 5. Recurrence of cancer originating from a site other than the brain. 6. Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that, in the investigator's opinion, gives reasonable suspicion of a disease or condition that may affect the interpretation of the results, render the patient at high risk from treatment complications or interferes with obtaining informed consent.

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.	NCT06038760
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.
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	Ourotech, Inc.
Principal Investigator The person who is responsible for the scientific and technical direction of the entire clinical study.	Matt Williams, FRCR PhD
Principal Investigator Affiliation	Imperial College London
Agency Class Category of organization(s) involved as sponsor (and collaborator) supporting the trial.	Industry, Other
Overall Status	Recruiting
Countries	United Kingdom
Conditions The disease, disorder, syndrome, illness, or injury that is being studied.	Brain Tumor, Glioma, Malignant, Ependymoma, Oligodendroglioma, Glioblastoma

Additional Details

This is a multicenter, observational pilot study that aims to determine the feasibility of using the Pear Bio tool in patients with primary solid brain tumors. Patients who are due to undergo clinically-mandated surgery will provide informed consent to donate excess tissue and a 40mL blood sample. The samples will be tested on the Pear Bio tool while the patient receives their standard of care treatment. As such, for this study, the result from the Pear Bio tool will not be used to inform the choice of treatment and the treating oncologist will be blinded to the assay results. The investigators will examine drug mechanism of action (MoA), differentiated response, and correlate that with outcomes seen in the patients treated in routine clinical practice.
