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.
