Summary

The purpose of this study is to evaluate the safety and tolerability of Natalizumab in children, adolescent and young adult patients with pulmonary metastatic osteosarcoma (pOS) and to assess clinical response associated with this treatment as well as overall survival.

Description

This study is a single-arm, open-label, proof of concept clinical trial in children, adolescent and young adult patients with unresectable pOS that have progressed, relapsed or are refractory to standard systemic therapy.

All participants will receive the study therapy and there will be dose escalation in a traditional 3 + 3 design during the Phase I study of this trial.

In the Phase II study of the trial, treatment will continue if the subject has Complete Response (CR), Partial Response (PR) or Stable Disease (SD) of pOS after every 3 cycles after the first 6 cycles but not beyond 24 cycles, unless it is judged to be in his/her best interest.

Approximately 3-9 subjects will be enrolled in the phase I part and 10-12 in the phase II part of this trial. Participants will be followed for toxicity for 30 days after treatment has been discontinued or until one of the protocol-defined reasons

This study seeks to evaluate if Natalizumab can be used safely and effectively as immunotherapy in children, adolescent and young adult patients with pOS. Natalizumab is currently Food and Drug Administration (FDA) approved for the treatment of T-cell mediated autoimmune disorders The study team will evaluate the safety and tolerability of Natalizumab as well as the clinical response associated with Natalizumab treatment and evaluate overall survival.

Eligibility

 Yes No Not Sure

Inclusion Criteria

Subjects must have histologic verification of pOS
Subjects must have measurable pulmonary disease per RECIST 1.1 documented by clinical, radiographic and histologic criteria, and have progressed, relapsed or become refractory to conventional therapy
Subjects must have recovered from the acute toxic effects with ≤ Grade 1 as defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CASE 1718 Page 20 Version date: 9/11/18 CTCAE) Version 5.0 of all prior chemotherapy and immunotherapy with the exception of alopecia, anorexia, bone pain, and tumor pain prior to entering this study
Myelosuppressive chemotherapy: Must have adequate recovery of counts from previous treatment prior to entry onto this study
Monoclonal antibodies: At least 3 half-lives must have elapsed since prior therapy that included a monoclonal antibody
Subjects must have a performance status corresponding to a Karnofsky ≥ 50% for participants > 16 years of age and Lansky ≥ 60 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
Subjects must have normal organ and marrow function as defined below
Adequate bone marrow function defined as
Peripheral absolute neutrophil count (ANC) ≥ 750/mcL
Platelet count ≥ 75,000/mcL (transfusion independent)
Hemoglobin ≥ 8.0 g/dL (may receive packed red blood cell transfusions)
Adequate liver function defined as
Total bilirubin ≤ 1.5 times the upper limit of normal for age
AST (SGOT) and ALT (SGPT) 2.5 X institutional upper limit of normal
Serum albumin > 2 g/dL
Adequate cardiac function defined as
Ejection fraction of ≥ 50% by echocardiogram
Subjects must have the ability to understand and the willingness to sign a written informed consent document if ≥ 18 years of age and an assent document if < 18 years of age. If < 7 years of age, no assent document is required

Exclusion Criteria

The presence of any of the following will exclude a subject from study
enrollment
Ongoing prior treatment toxicities > Grade 1 according to NCI CTCAE Version 5.0 with the exception of alopecia, anorexia, bone pain and tumor pain
Subjects receiving any other investigational agents
History of allergic reactions attributed to compounds of similar chemical or biologic composition to Natalizumab
Subjects currently on immunosuppressive therapy
Subjects with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, liver failure, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Pregnant or breastfeeding women are excluded from this study because Natalizumab crosses the placenta and can increase the risk of spontaneous abortion. There is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with Natalizumab, therefore breastfeeding should be discontinued if the mother is treated with Natalizumab
Female participants of childbearing potential are not eligible unless a negative pregnancy test result has been obtained
Women of childbearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
HIV-positive subjects and HIV-positive subjects on antiretroviral therapy are ineligible because of the risk for developing a lethal infection when treated with immunosuppressive therapy
Participants who have or have had progressive multifocal leukoencephalopathy (PML)
Participants whose pulmonary metastatic disease can be completely surgically resected
