Tovorafenib for Treatment of Craniopharyngioma in Children and Young Adults

Newly diagnosed craniopharyngioma, as based on imaging characteristics and central radiology review. Participants will initially be screened within confines of a screening consent and only those participants with findings consistent with craniopharyngioma and without findings suggesting an indeterminate lesion or lesion of an alternative diagnosis (including abnormal tumor markers found in blood or cerebral spinal fluid (CSF), if completed as part of standard of care (SOC) work-up or if lesion concerning for alternate diagnosis) will move ahead with enrollment on the treatment protocol. Additionally, for participants that have undergone initial biopsy to confirm diagnosis, are within 6 weeks of radiographic diagnosis, and are planned to undergo follow up second surgery for additional tumor resection as per standard of care recommendations, these participants will also be considered eligible.

Participants must be surgical candidates for biopsy or resection and planned for standard of care biopsy or resection.

Recurrent craniopharyngioma, as based on histologic confirmation at time of initial diagnosis (participants with Adamantinomatous craniopharyngioma (ACP) will only be eligible for the recurrent arm).

Recurrent craniopharyngioma without prior histologic confirmation will initially be screened within confines of a screening consent and only those participants with findings consistent with craniopharyngioma and without findings suggesting an indeterminate lesion or lesion of an alternative diagnosis (including abnormal tumor markers found in blood or CSF, if completed as part of SOC work-up or if lesion concerning for alternate diagnosis) will move ahead with enrollment on the treatment protocol.
