简要总结
This phase 2 trial will evaluate the activity of Panobinostat in combination with Everolimus for children with gliomas harboring H3.1 or H3.3K27M mutation, including newly diagnosed high-grade glioma or DIPG (diffuse intrinsic pontine glioma) after radiation (stratum A) and recurrent/progressive glioma (grade II-IV, including DIPG) (stratum B).

入选标准
- •All patients and/or a legal guardian must sign institutionally approved written informed consent and assent documents.
- •Patient must be greater than 2 years and less than 30 years
- •BSA (body surface area) greater than 0.3 m2
- •Functional status: Karnofsky > 50% for patients > 16 years of age and Lansky > 50% for patients < 16 years of age (Karnofsky and Lansky is a scoring system used to quantify the general well being of cancer patients where 100% represents perfect health and 0% represents death). Neurologic deficits in patients with CNS tumors must have been relatively stable for a minimum of 7 days. Patients who are unable to walk because of paralysis, but who are able to sit in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
- •Adequate bone marrow function
- •Adequate liver function
- •Adequate renal and metabolic function
- •Urine protein:creatinine (UPC) ratio of < 1; or a urinalysis that is negative for protein; or 24-hour urine protein level < 1000 mg/dL
- •Patients must have Magnesium > 1.5 mg/dL and potassium > 3.5 mmol/L
- •Patients with known seizure disorder must have seizures adequately controlled with non- enzyme inducing antiepileptic medications
- •No increase in steroid dose within the past 7 days.
- •STRATUM A: histological confirmation of a newly diagnosed high-grade glioma or DIPG or STRATUM B: histological confirmation of a recurrent or progressive grade II-IV glioma (including DIPG) [histology can come from tissue at diagnosis or relapse]
- •Primary brain or spine tumor are eligible, including tumors with metastases, multiple lesions
- •Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy.
- •Myelosuppressive chemotherapy: Must not have received within 3 weeks (6 weeks if prior nitrosourea).
- •Hematopoietic growth factors: At least 7 days since the completion of therapy with a growth factor, 14 days for long-acting (e.g. PEG-filgrastim)
- •Biologic (anti-neoplastic agent): At least 7 days or 3 half-lives (whichever is longer) since the completion of therapy with a biologic agent.
- •Radiation therapy: Strata A: ≥ 2 weeks and ≤ to 12 weeks must have elapsed from radiation. Strata B: ≥ 2 weeks must have elapsed from focal radiation.
- •Surgery: > 3 weeks from major surgery. If recent craniotomy, adequate wound healing must be determined by neurosurgical team.
- •Autologous Stem Cell Transplant or Rescue: No evidence of active graft vs. host disease and ≥ 4 weeks must have elapsed.
- •H3K27M mutation: Participants must have a mutation in H3.3 K27M or H3.1 K27M as identified by tumor (FFPE or fresh, diagnosis or relapse tissue, but relapse tissue preferred) sequencing, or by CLIA-certified immunohistochemistry staining positive for H3K27M, as defined by review by U of M neuro-pathology.
排除标准
- •Patients who are breastfeeding, pregnant or refuse to use an effective form of birth control are excluded. Abstinence is considered an effective form of birth control.
- •Patients with uncontrolled infection are excluded.
- •Inability to swallow oral pill (panobinostat does not have liquid formulation).
- •Other medications: Patients receiving other anti-neoplastic agents are excluded; patients on enzyme-inducing anticonvulsive agents are excluded; patients requiring strong CYP3A4 or PGP inducers or inhibitors are excluded; patients on steroids for symptom management must be on a stable dose for 7 days prior to start of treatment.
- •Allogeneic stem cell transplant: Patients within 1 year of allogeneic stem cell transplant, patients with active GVHD or requiring immunosuppression are excluded.
- •Previous hypersensitivity to rapamycin or rapamycin derivatives.
- •Baseline QTc of >450 msec on EKG OR electrolyte imbalance predisposing to QTc prolongation (baseline ≥ Grade 1 hypokalemia or hyperkalemia; and baseline ≥ Grade 2 Ca++, Mg++, phosphate abnormalities). Repletion/correction is allowed to achieve eligibility. Use of QTC prolonging medications will be monitored throughout the trial.

结局指标
主要结局
Median Progression Free Survival (PFS) at 1 Year
时间窗: 1year
Median PFS at 1 year for stratum A will be measured. Progression is defined as \> 25% increase in the size of the tumor or appearance of new lesions.
Median Progression Free Survival (PFS) at 2 Years
时间窗: 2years
Median PFS at 1 year for stratum A will be measured. Progression is defined as \> 25% increase in the size of the tumor or appearance of new lesions.
Overall Survival at 2Years
时间窗: 2years
The proportion of patients alive at 2 years for stratum A.
Overall Response Rate (ORR) After Two Cycles of Panobinostat + Everolimus
时间窗: 84 Days
Overall Response Rate (ORR) After Two Cycles of Panobinostat + Everolimus for stratum B. Overall response is defined as a partial or complete response. Partial response is defined as a ≥50% decrease in size of tumor in comparison to baseline measurements. Complete response is defined as the disappearance of all abnormal signal. This includes return to normal size of the brainstem for brainstem lesions.
Overall Survival at 1Year
时间窗: 1year
The proportion of patients alive at 1 year for stratum A.
