Conditions: Solid Tumor Osteosarcoma
Keywords: Advanced solid tumor Bone metastasis and advanced pretreated osteosarcoma Phase I trial Dose escalation and expansion cohort Biomarkers study
Allocation: NA | Intervention model: SEQUENTIAL
Enrollment: 23
Healthy volunteers: no

Brief summary:
This is a prospective open-labeled phase I trial based on a dose escalating study design assessing two dose levels of sirolimus when prescribed in combination with metronomic cyclophosphamide (CP), methotrexate (MT) and zoledronic acid (ZA) followed by an expansion cohort once the Maximum Tolerated Dose (MTD) is established.

Detailed description:
The dose escalation part of the trial will be concerned on adults with advanced solid tumor with bone metastasis and young and adult patients with unresectable locally advanced or metastatic osteosarcoma.

The Expansion cohort will be conducted on young and adult patients with unresectable locally advanced or metastatic osteosarcoma.

Arms:
arm 1: Drug : Metronomic Cyclophosphamide, Methotrexate, Sirolimus, Zoledronic acid Assessment of the maximum tolerated dose of sirolimus Cyclophosphamide, Methotrexate and Sirolimus will be administrated orally. Zoledronic Acid will be administrated by infusion (IV).

Interventions: intervention 1: Sirolimus combined with CP, MT and ZA
Intervention descriptions: intervention 1: Cyclophosphamide, Methotrexate and Sirolimus will be administrated orally. Zoledronic Acid will be administrated by infusion (IV).
