Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Dose Escalation Arm

Arm Description

Dose Levels 1-3 will consist of treatment with radiopharmaceutical (153Sm-DOTMP) alone. If the maximally tolerated dose (MTD) has not been reached at Level 3, external beam radiotherapy will be added to each of Levels 4-6. Participants enrolled on Dose Levels 4-6 will be treated with external beam radiotherapy to all radiographically evident sites of disease. If an MTD has not been determined at Level 6, the study will end and Dose Level 6 will be declared the Recommended Phase 2 Dose. Participants will be given prophylactic / supportive treatment protocols including Calcium Carbonate, mozobil, and neupogen injectable product.

Outcomes

Primary Outcome Measures

Maximally Tolerated Dose
The maximally tolerated dose (MTD) of 153Sm-DOTMP will be determined. The MTD will be defined as the dose that produces a dose limiting toxicity (DLT) in 30% of the participants. The dose limiting toxicity is the dosage at which side effects are serious enough to prevent an increase in dose or level of that treatment. DLTs will be defined as any grade 3, 4, or 5 non-hematologic toxicity experienced during a 42-70 day observation window.

Secondary Outcome Measures

Overall Survival
The overall survival of participants with bone metastatic osteosarcoma will be determined. Overall survival is defined as the time from enrollment in the study until death. Observation begins at study enrollment and terminates upon death of the subject.
Time To Progression
The time to progression of participants with bone metastatic osteosarcoma will be determined. Time to progression is defined as the time from study enrollment until the first radiographic evidence of progressive disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST). RECIST is a set of published rules that help define whether cancer patients improve, stay the same, or get worse with treatment. This study uses the revised RECIST 1.1 guidelines.
Clinical Response Rate 30 days post treatment
Participants will undergo radiographic evaluation 30 days after completion of all protocol therapy. The response of each tumor to treatment will be determined based on RECIST 1.1 criteria. Clinical response will be defined as either stable disease or a decrease in the size of the tumor by radiographic imaging (which may include CT or MRI) using RECIST 1.1 criteria.
Clinical Response Rate 4 months post treatment
Participants will undergo radiographic evaluation 4 months after completion of all protocol therapy. The response of each tumor to treatment will be determined based on RECIST 1.1 criteria. Clinical response will be defined as either stable disease or a decrease in the size of the tumor by radiographic imaging (which may include CT or MRI) using RECIST 1.1 criteria.
Clinical Response Rate 8 months post treatment
Participants will undergo radiographic evaluation 8 months after completion of all protocol therapy. The response of each tumor to treatment will be determined based on RECIST 1.1 criteria. Clinical response will be defined as either stable disease or a decrease in the size of the tumor by radiographic imaging (which may include CT or MRI) using RECIST 1.1 criteria
Clinical Response Rate 12 months post treatment
Participants will undergo radiographic evaluation 12 months after completion of all protocol therapy. The response of each tumor to treatment will be determined based on RECIST 1.1 criteria. Clinical response will be defined as either stable disease or a decrease in the size of the tumor by radiographic imaging (which may include CT or MRI) using RECIST 1.1 criteria.

5. Study Description

Brief Summary
This is a dose finding study of a novel radiopharmaceutical agent, 153Sm-DOTMP. It will be studied alone and then in combination with external beam radiotherapy. The study design includes six cohorts, Levels 1-6. The first three cohorts of participants will receive 153Sm-DOTMP alone, and if this is determined to be safe, subsequent cohorts will receive the radiopharmaceutical followed by external beam radiotherapy.
Detailed Description
This is a dose escalation study of a new radiopharmaceutical agent, 153Sm-DOTMP. Eligible participants will have osteosarcoma metastatic to bone, other solid tumors with bone metastases, or an unresectable localized osteosarcoma. Because of anticipated prolonged myelosuppression, participants will have a peripheral blood stem cell harvest. They will then be treated with 2 doses of 153Sm-DOTMP given 7 days apart. Twenty-four days after the initial dose, stem cells will be reinfused if needed. The first three cohorts of participants will receive only radiopharmaceutical. If Dose Level 3 is not the maximally tolerated dose (MTD), subsequent dose levels will include external beam radiotherapy, administered beginning on Day 15. The dose of external beam radiotherapy will be determined by dosimetry studies performed after each administration of study agent, and will be targeted to a tumoricidal dose of radiation. All participants will have disease re-evaluation 30 days following completion of all study treatments, and then at 4, 6, 8, and 12 months, unless they experience disease progression.
