Phase

PHASE2

Detailed Description:

PRIMARY OBJECTIVE: I. To determine progression free survival and maintenance of quality of life at 12 months as based on physical function and compared to historical controls. SECONDARY OBJECTIVES: I. To identify proportion of participants with visual deficits at 1-year, 2-year, and 3-year follow-up. II. To identify proportion of participants with neuroendocrine deficits at 1-year, 2-year, and 3-year follow-up. EXPLORATORY OBJECTIVES: I. To assess Quality of Life (QOL) and cognitive measures in children and young adults with newly diagnosed or recurrent craniopharyngioma. II. To perform Immunohistochemistry (IHC)/Multiplexed ion beam imaging on pre-and post-treatment tumor tissue (as available), including at time of progression, to assess for patterns of protein density and spatial relationship in intact tumor tissue and elucidate changes in tumor tissue over the course of therapy and disease evolution. III. To perform single-cell (scRNA) RNA sequencing on pre- and post-treatment tumor tissue (as available), including at time of progression, to identify and characterize distinct cell subsets that make up the components of craniopharyngioma and elucidate changes in cell subsets over the course of therapy and disease evolution. IV. To perform proteomic analysis on pre- and post-treatment tumor tissue, including at time of progression, to characterize distinct proteins and transcriptome pathways that are active in different tumor compartments and elucidate changes in proteomic profiles over the course of therapy and disease evolution. V. To perform ELISA array/multiplex analysis on pre- and post-treatment cyst fluid, including at time of progression, to characterize distinct cytokine profiles and elucidate changes in cytokine profile over the course of therapy and disease evolution. VI. Microbiome and flow cytometry studies in the context of imaging and clinical outcomes using descriptive statistics. VII. To assess patient and/or proxy satisfaction with study participation via patient-reported outcome (PRO) measures. VIII. To assess patient and/or proxy satisfaction with study participation via patient-reported outcome (PRO) measures in the context of race ethnicity and other health related social risks. IX. To assess on therapy toxicity in the context of race, ethnicity and other health related social risks. TREATMENT GROUPS: Participants will be divided into 2 cohorts: newly diagnosed or recurrent craniopharyngioma, both planned for standard of care biopsy/resection. All newly diagnosed participants or recurrent craniopharyngioma without histologic diagnosis will be enrolled on a screening consent for central imaging review to ensure imaging supports diagnosis of craniopharyngioma before enrollment onto the treatment protocol. After enrollment onto treatment protocol, each patient in each arm will receive one dose of tovorafenib prior to planned biopsy or resection. Participants with measurable disease will then continue on maintenance therapy. Participants who have a gross total resection (GTR) will enter into the follow-up only phase.

Criteria
Inclusion Criteria
  • Newly Diagnosed Participants
    • * 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 Participants
      • * 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.
      • * Participants should be surgical candidates for biopsy or resection. If participants are not surgical candidates, but have available archival tumor tissue, they will be enrolled into the exploratory cohort.
      • * Participants must be willing to provide archival tissue, a minimum of 10-20 paraffin embedded unstained slides OR 1 block with tumor content of 40% or greater is required. Participants who do not meet this criteria may be discussed on a case-by-case basis with the Study Chair(s).
      • * Participants can have been previously treated with surgical resection alone, cyst drainage and biopsy alone, radiation therapy, other systemic therapies, or any combination thereof.
      • * Prior Therapy
        • * Had their last dose of myelosuppressive chemotherapy \>= 21 days prior to study registration (\>=42 days if nitrosourea therapy).
        • * Had their last dose of hematopoietic growth factor \>=14 days (long-acting growth factor) or \>=7 days (short-acting growth factor) prior to study registration, or beyond the time during which adverse events (AEs) are known to occur.
        • * Had their last dose of biologic (anti-neoplastic agent) \>=7 days prior to study registration, or beyond the time during which AEs are known to occur.
        • * Had their last dose of monoclonal antibodies \>=21 days prior to study registration.
        • Radiation
          • * Had their last fraction of local irradiation to primary tumor \>=12 weeks prior to registration; investigators are reminded to review potentially eligible cases to avoid confusion with pseudo-progression.
          • * At least 14 days after local palliative radiation (small-port).
          • All Participants
            • * Age 1 to 39 years.
            • * Participants continuing on maintenance therapy after standard of care biopsy/resection must have measurable disease, as defined as lesions that can be accurately measured in two dimensions (longest diameter to be recorded) with a minimum size of no less than double the slice thickness. Previously irradiated lesions are considered non-measurable except in cases of documented progression of the lesion since the completion of radiation therapy. Participants without measurable disease may continue on study and will be followed for study endpoints, but will not be included as part of target accrual.
            • * Performance Score: Karnofsky \>= 50 for participants \> 16 years of age and Lansky \>= 50 for participants \<= 16 years of age. Participants who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
            • * Corticosteroids: Participants who are receiving dexamethasone must be on a stable or decreasing dose for at least 1 week prior to registration. The participant steroid dose should be no more than a steroid-equivalent of dexamethasone 0.1 mg/kg/day (or maximum 4mg/day; whichever is the lower dose) at time of enrollment. Participants that have been stable on physiologic hormone replacement for hypopituitarism are allowed.

                    • * Participants should not have previously received any RAS-pathway, but have not received Tovorafenib will be eligible.
                    • All Participants
                      • * Rapidly progressive symptoms that require urgent surgery or radiation therapy, which would prevent central review and or preclude participation with tumor-directed medical management alone.
                      • * Uncontrolled symptoms of neuroendocrine dysfunction such as diabetes insipidus, hypothyroidism, panhypopituitarism (participants can be on supplemental medications for hormonal repletion; however, should be on controlled doses for at least 2 weeks prior to enrollment).
