简要总结
This clinical trial seeks to determine if avelumab will be effective in facilitating removal of all gross tumor in the event of a relapse of osteosarcoma in pediatric patients. Avelumab will be evaluated using dosing that has previously been determined in adult studies.
Primary Objectives:
- To estimate the response rate to 4 cycles of avelumab in patients with recurrent or progressive osteosarcoma.
- To estimate the 16-week progression free survival of patients with recurrent or progressive osteosarcoma after treatment with avelumab.
Secondary Objective:
- To describe the toxicities associated with the administration of avelumab in patients with recurrent or progressive osteosarcoma.
- To assess the quality of life of patients with recurrent or progressive osteosarcoma undergoing treatment with avelumab, and to explore relationships between clinical factors and patient-reported health-related quality of life (HRQOL) outcomes.
Exploratory Objectives:
- To explore factors associated with response in patients treated with avelumab after recurrent or progressive osteosarcoma (e.g. tumor PD-L1 expression).
- To measure parameters of immune activation including subsets of peripheral blood mononuclear cells (PBMCs) and serum markers of immune activation.
- To evaluate the role of T-cells in immune checkpoint blockade via measures of cell proliferation, co-inhibitory receptor expression on CD8 T cells, T cell repertoire, and epigenetic programming.
详细描述
This is a Phase 2 study using a traditional Simon two-stage design. Patients 12 years or greater with recurrent/refractory osteosarcoma will be administered avelumab at a dose of 10 mg/kg intravenously (IV) over 60 minutes on days 1 and 15 of each cycle, with a cycle lasting 28 days.
Patients will receive avelumab every 2 weeks in cycles of 28 days for up to 24 months, or 26 cycles. Progression free survival and response to therapy after 4 cycles of treatment will be assessed. In addition, the toxicity profile of avelumab in this population will be closely monitored.

- •Radiation therapy (RT): ≥ 2 weeks for local palliative RT (small port); ≥ 6 months must have elapsed if prior craniospinal RT or if ≥ 50% radiation of the pelvis; ≥ 6 weeks must have elapsed if other substantial bone marrow (BM) radiation.
- •Organ Function Requirements:
- •Adequate bone marrow function defined as:
- •Peripheral absolute neutrophil count (ANC) ≥ 1500/mm3
- •Platelet count ≥ 100,000/mm3 (transfusion independent)
- •Hemoglobin ≥ 9.0 g/dL (may receive RBC transfusions)
- •Adequate renal function defined as:
- •Creatinine clearance or radioisotope GFR ≥70 mL/min/1.73m2 OR
- •Serum creatinine based on age/gender as follows: (threshold creatinine values were derived from the Schwartz formula for estimating GFR).
- •Age is: 12 to <13 years, then maximum creatinine is 1.2 mg/DL for male and female.
- •Age is: 13 to <16 years, then maximum creatinine is 1.5 mg/DL for male and 1.4 mg/DL for female.
- •Age is: ≥16 years, then maximum creatinine is 1.7 mg/DL for male and 1.4 mg/DL for female.
- •Adequate liver function defined as:
- •Total Bilirubin ≤ 1.5x the institutional upper limit of normal (IULN) for age
- •ALT (SGPT) and AST (SGOT) < 2.5 x IULN for age (or < 5 x IULN for patients with documented metastatic disease to the liver)
- •Serum albumin > 2 g/dL
- •Serum lipase ≤ upper limit of normal (IULN).
- •Patients must have documented pulse oximetry ≥ 92% on room air.
- •Female patients of childbearing potential must have a negative serum or urine pregnancy test within 7 days of enrollment.
- •Male or female patients who are sexually active and of reproductive potential must agree to use an effective contraceptive method throughout the study and for at least 60 days after last avelumab treatment administration. Abstinence is an acceptable form of contraception.
- •Patients must not currently be using other investigational agents.
- •Patients must not currently be using other anti-cancer agent.
- •Patients must be able to comply with the safety monitoring of the study in the opinion of the investigator.
- •Written, informed consent and assent following Institutional Review Board, NCI, FDA and OHRP guidelines.
排除标准
- •Central nervous system (CNS) metastases.
- •Current use of immunosuppressive medication, EXCEPT for the following: a. intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection); b. Systemic corticosteroids at physiologic doses ≤ 10 mg/day of prednisone or equivalent; c. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication).
- •Active autoimmune disease that might deteriorate when receiving an immuno-stimulatory agent. Patients with diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid diseases not requiring immunosuppressive treatment are eligible.
- •Active infection requiring systemic therapy.
- •Known history of testing positive for HIV or known acquired immunodeficiency syndrome.
- •Hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or HCV RNA if anti-HCV antibody screening test positive).
- •Patient who has received vaccination within 4 weeks of the first dose of avelumab and while on trials is prohibited except for administration of inactivated vaccines.
- •Known prior severe hypersensitivity to investigational product or any component in its formulations, including known severe hypersensitivity reactions to monoclonal antibodies (NCI CTCAE v4.03 Grade ≥ 3).

主要结局
Progression-free Survival
时间窗: At the end of 4 cycles of avelumab (approximately 4 months)
The study is designed by treating RECIST response \[complete response + partial response (CR+PR)\] after 4-cycle treatment of avelumab and the 16-week progression-free survival (PFS) as dual binary endpoints. Patients who fail to be evaluated at the end of the 4-cycle will be counted as failure.
