Brief Summary:

patients with progressive/relapsed solid tumors who failed first line therapy , will be treated biweekly with the anti PD1- Nivolumab. at least one month after treatment initiation low dose cyclophosphamide will be started .

patients on trial will submit tissue and blood tests for whole exome an immune genomic signature. patients will also undergo repeated immunophenotype as part of follow up.


Condition or disease Intervention/treatment Phase
Antibodies, Neoplasm Drug: Nivolumab,low dose cyclophosphamide Phase 1 Phase 2

Detailed Description:

Programmed cell death 1 (PD-1) is an inhibitory receptor that prevents immune activation. PD-1 blockade can mediate reactivation of immune mediated tumor killing leading to tumor regression . Another mechanism of tumor associated immune inactivation is elevation of rates of T regulatory cells. This process may be prevented by treatment with low dose cyclophosphamide.

Objective:

This study will evaluate safety and tolerability of the anti PD1 antibody Nivolumab combined with other immunomodulating treatments, in pediatric patients with relapsed/progressive solid tumors

Method:

Patients will be treated with IV Nivolumab 3mg/kg over 60 minutes on day 1 and 15 of each cycle of 28 days.

  1. Dose finding phase:

    1. Six patients will be accrued for the first cohort and treated for 1 month
    2. If an adverse event >grade 2 will occur in>2 patients, study medication dose will be reduced by 25% and another cohort of 6 patients will be accrued on the reduced dose.
    3. Dose finding cohorts will be accrued until determination of a dose with allowed DLT
  2. Expansion phase

    1. Following dose determination patients will be accrued, to the final number of 30 patients
    2. Cyclophosphamide at the dose of 50 mg/dayx7days every 14 days (one week on one week off ) will be started . immunophenotype will be done every 28 days and dose of cyclophosphamide will be elevated by 25mg /day every month until highest ratio of CD8/CD25FOXP3 cells will be reached for every child
    3. All patients will be treated for 1 year or until imaging proven disease progression.
  3. Required follow up

    1. All patients will undergo tumor bed imaging (CT/MRI-based on tumor location) with metastatic evaluation (according to standar follow up) every 4 months
    2. Tumor response will be measured based on RECIST criteria
    3. Toxicity assessment will be done according to the CTCAE v. 4.03

c. Collateral studies:

  1. Immunohistochemical analysis for PD1 and PDL1 will be done on pretreatment paraffin embedded tissue to estimate it's ability to predict response.
  2. Immune profile of peripheral blood lymphocytes including CD3+, CD4+, CD8+ FOX P3+ cells and it's correlation to objective response to therapy.
  3. Exome sequencing of the tumor and peripheral blood will be done for every patient.

Exome will be evaluated for driver mutations and immunologic genomic signature.

Arm Intervention/treatment
Experimental: progressive/relapsed solid tumors
patient with progressive/relapsed solid tumors who failed first line therapy
Drug: Nivolumab,low dose cyclophosphamide
treatment with IV Nivolumab 3mg/kg every 2 weeks . after a month-addition of low dose cyclophosphamide at a starting dose of 50 mg/kg/day x7 days every 14 days with dose adaptation based on level of Tregulatory cells on follow up immunophenotype.




Primary Outcome Measures :
  1. Event free survival [ Time Frame: 6 months ]
    Rate of patients with stable disease/tumor response at 6 months

  2. Overall survival [ Time Frame: 6 and 12 months ]
    Rate of patients alive at 6 months and 12 months


Secondary Outcome Measures :
  1. evaluation of predictors for response [ Time Frame: 12 months ]
    correlation between levels of PD1 receptor expression in the tumor and genomic signature with response

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Ages Eligible for Study: 12 Months and older
  2. Patients must have had histologic verification of malignancy at original diagnosis or relapse

    Eligible pathologies:

    1. neuroblastoma following lack of complete response to at least two lines of therapy
    2. rhabdomyosarcoma following progression after first line therapy
    3. Ewing sarcoma following progression after second line of therpy
    4. Osteosarcoma following progression after first line of therapy all other pathologies will be discussed with PI
  3. Patients must have measurable disease
  4. Patient's current disease state must be one for which there is no known curative therapy
  5. Karnofsky >= 50 for patients > 16 years of age and Lansky >= 50 for patients =< 16 years of age; patients 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
  6. Patients must have fully recovered from the acute toxic effects of all prior anti-cancer treatment

    1. At least 21 days after the last dose of myelosuppressive chemotherapy (42 days if prior nitrosourea)
    2. At least 42 days after the completion of any type of immunotherapy, e.g. tumor vaccines
    3. at least 56 days must have elapsed after transplant or stem cell infusion; patients with prior allogeneic transplants are not eligible
