About this trial

This will be a phase II, single arm study of osteosarcoma patients with fully resected pulmonary metastases. The MTD corresponds to the dosage recommendations of the manufacturer of Iscador® P which is licensed in Sweden, New Zealand, South Korea, Germany and Switzerland for the treatment of solid tumors and precancerous lesions.

The study population includes patients with relapse of osteosarcoma in the lung following surgical resection of all gross disease (2nd or greater CR). Following completion of final thoracotomy, they will be treated with Iscador® P at concentrations up to the MTD with surveillance imaging via CT scan to monitor for relapsed disease.

Eligibility criteria

Qualifiers

Histologic diagnosis of osteosarcoma.

Patients with at least one episode of relapse in the lung (without limitation of number of episodes), following surgical resection of all gross metastatic disease.

Surgical resection of all possible sites of suspected pulmonary metastases in order to achieve a complete remission within 8 weeks prior to study enrollment. Note: If surgery related changes such as atelectasis are seen on the post-operative CT scan, patients will remain eligible to enroll as long as the operating surgeon believes that all sites of metastases were resected. Patients with positive microscopic margins will be eligible to enroll.

Pathological confirmation of metastases from at least one of the resected sites.

Disqualifiers

Another known malignancy other than osteosarcoma that is progressing or requires active treatment.

Any prior history of other cancer within the prior 5 years with the exception of adequately treated basal cell carcinoma or cervical intraepithelial neoplasia [CIN]/cervical carcinoma in situ or melanoma in situ).

Active infection requiring systemic therapy.

Known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
