bio-11006 for osteosarcoma and ewing's sarcoma lung metastases

Conditions: Osteosarcoma Metastatic; Ewing's Sarcoma Metastatic

Summary: this is a phase 2 study of an investigational drug, bio-11006, for the treatment of lung metastases in pediatric patients with advanced osteosarcoma or ewing's sarcoma. this study will enroll up to 10 patients aged between 5 and 21 at nicklaus children's hospital in miami, fl. patients will receive bio-11006 in addition to chemotherapy consisting of gemcitabine and docetaxel. this study will test the hypothesis that bio-11006 will enhance the effect of the gemcitabine and docetaxel chemotherapy to treat lung metastases in osteosarcoma and ewing's sarcoma.

this is a phase 2, controlled study of bio-11006 peptide given in addition to gemcitabine and docetaxel (gemtax) in the treatment of patients with advanced osteosarcoma or ewing's sarcoma with lung metastases. patients will receive bio-11006 in addition to gemtax chemotherapy, which is a current institutional treatment option for recurrent osteosarcoma and ewings's sarcoma. the bio-11006 inhalation solution will be given by mouth inhalation twice daily. bio-11006 will be given during the first three cycles and then will be stopped. patients will continue on gemtax for up to 6 additional cycles and will be clinically assessed before every cycle and have standard-of-care imaging assessments after cycle 3, 6 and 9. if the patient shows lung progression (either clinical or on imaging) at any point after cycle 4 has been given, but had shown at least a partial response during the tumor assessment after cycle 3, bio-11006 may be re-started at the discretion of the investigator and continued for the duration of the gemtax treatment. subjects will be followed for disease status during routine clinical follow-ups for 9 months post the end of study treatment. the trial will be conducted at a single site.
