Study Overview

• Status: Recruiting
• Conditions: Craniopharyngioma; Craniopharyngioma, Child; Recurrent Craniopharyngioma
• Intervention / Treatment: Drug: Nivolumab; Drug: Tovorafenib

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 statistic.

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 Groups (newly diagnosed craniopharyngioma, recurrent craniopharyngioma without histological diagnosis) with 3 treatment arms within each group (Neoadjuvant nivolumab, Neoadjuvant Tovorafenib, Neoadjuvant combination nivolumab plus Tovorafenib). There will also be a separate Non-biopsy/resection arm within the Recurrent Craniopharyngioma group.

Participants will be randomized in a 1:1:1 and will receive one dose of assigned drug prior to planned biopsy or resection. Participants with measurable disease will then continue on combination maintenance therapy. Participants may continue treatment for up to 24 months total and will be followed up for 3 years after enrollment into the study.

• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

Newly Diagnosed Participants:

• Newly diagnosed craniopharyngioma diagnosis 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 4 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 and must be willing to provide 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.

• Organ Function Requirements:

  • Adequate Bone Marrow Function defined as:

    • Peripheral absolute neutrophil count (ANC) >=1000/mm3.
    • Platelet count >= 100,000/mm3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment).

    ---A serum creatinine < 1.5 Upper Limit normal (ULN) based on age and gender.

  • Adequate Liver Function defined as-

    • Bilirubin (sum of conjugated + unconjugated) <= 1.5 x upper limit of normal (ULN) for age (except in participants with documented Gilbert syndrome).
    • Serum glutamic-pyruvic transaminase (SGPT)((alanine aminotransferase (ALT)) <= 3 x ULN.
    • Serum albumin >=2 g/dL (20g/L).
  • Adequate Neurologic Function defined as participants with seizure disorder may be enrolled if well controlled. Participants on non-enzyme inducing anticonvulsants may be excluded pending interaction(s) with study drug.
  • Adequate Pancreatic Function defined as serum lipase <= 1.5 x ULN at baseline.
  • Adequate Pulmonary Function defined as no evidence of dyspnea at rest, no exercise intolerance due to pulmonary insufficiency, and a pulse oximetry of > 92% while breathing room air.
• The effects of Tovorafenib and nivolumab on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and 6 months after completion of Tovorafenib and/or nivolumab administration, whichever is later. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
• A legal parent/guardian or participants must be able to understand, and willing to sign, a written informed consent and assent document, as appropriate.

Exclusion Criteria:

Newly Diagnosed Participants:

- Participants should not have undergone any previous tumor-directed therapy.

• Participants who have had chemotherapy or radiotherapy within 3 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from acute adverse events due to agents administered more than 4 weeks earlier.
• Participants must be at least 1 week since the completion of therapy with a biologic or small molecule agent. For any agent with known adverse events that can occur beyond 1 week after administration, the period prior to enrollment must be beyond the time during which adverse events are known to occur. Such participants should also be discussed with study chairs.
• Participants should not have previously received any RAS-pathway directed therapy combined with PD-1 inhibition. However, individual therapy with either of these individual agents will be allowed. Such subjects should be discussed with study chairs.

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).
• Participants with a history or current evidence of central serous retinopathy (CSR), retinal vein occlusion (RVO), or ophthalmopathy present at baseline who would be considered a risk factor for CSR or RVO.
• Clinically significant active cardiovascular disease, or history of myocardial infarction, or deep vein thrombosis/pulmonary embolism within 6 months prior to registration, ongoing cardiomyopathy, or current prolonged QT interval corrected for heart rate by Fridericia's formula (QTcF) interval > 440 ms based on triplicate ECG average.

Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. Note: Participants that are currently using inhaled, intranasal, ocular, topical or other non-oral or non-IV steroids are not necessarily excluded from the study but need to be discussed with the study chair.
• Participants with a >= Grade 2 hypothyroidism due to history of autoimmunity are not eligible. (Note: Hypothyroidism due to previous irradiation or thyroidectomy will not impact eligibility).
• Participants who have received prior solid organ or bone marrow transplantation are not eligible.
• Women of childbearing potential must not be pregnant or breast-feeding.
• Current treatment with a strong cytochrome P4502C8(CYP2C8) inhibitor or inducer other than those allowed per Section 5.6.1. Medications that are substrates of CYP2C8 are allowed but should be used with caution.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression free survival rate (PFS)	Progression-free survival is defined as the time of documented response until disease progression as defined by Response assessment in neuro-oncology criteria (RANO) criteria. PFS will be reported by overall group at 12 months.	Up to 12 months
Changes in scores on the Physical functioning subscale of the Pediatric Quality of Life Inventory (PedsQL) over time	Scores over time from the PedsQL 4.0 Generic Core physical function domain rating form, which have multidimensional child self-report and parent proxy report scales to assess health-related quality of life (QOL) in children, adolescents, and young adults ages 2 - 25 years will be reported. Physical functioning, is the sub-scale of interest for this protocol. Items on the physical functioning sub-scale are scored on a 5-point Likert scale with raw scores ranging from 0- 4. Items are reversed scored and linearly transformed to a 0-100 scale. If more than 50% of the items in the scale are missing, the Scale Scores should not be computed. Higher scores indicate a higher level of physical functioning	Up to 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Proportion of participants with visual deficits over time	Teller acuity testing using Teller Acuity Cards® (TAC) II will be performed on every time participants undergo a radiographic disease assessment. Visual acuity (VA) testing will be performed in each eye separately at a distance of 55 centimeters in all participants. The tester will use the "two down, one up" protocol to achieve the best VA score. Acuity will be reported in logarithm of the minimum angle of resolution (logMAR). Visual field testing will be performed by confrontation and reported as the number of quadrants (0, 1, 2, 3, or 4) with visual field deficits. Optic discs will be assessed for the presence or absence of pallor and edema.The proportion of participants with recorded visual deficits over time based on these assessments will be reported.	Up to 5 years
Proportion of participants with neuroendocrine deficits	The proportion of participants with presence of new neuroendocrine deficits defined as hypothalamic obesity, diabetes insipidus, growth hormone deficiency, adrenal insufficiency from baseline will be reported.	Up to 5 years
