- 5. Injectable tumor present
Phase 1: Exclusion Criteria:
1. Prior exposure to 300 mg/m^2 of Dox HCl or DOXIL / CAELYX ® or 600 mg/m^2 of Epirubicin HCl

1. Locally advanced or metastatic, unresectable, soft-tissue sarcoma of intermediate or high grade with measurable disease.

- 2. Life expectancy >12 weeks (about 3 month)
Phase 2a Expansion Group 2 (Unresectable STS): Exclusion
1. Prior exposure to anthracyclines

- 2. Treatment naive extremity tumors
Phase 2a Expansion Group 3a (Head and Neck): Inclusion
1. Patients with histologically or cytologically confirmed squamous-cell carcinoma of the head and neck (HNSCC) who meet any of the following a) confirmed relapsed HNSCC or b) metastatic at initial presentation HNSCC

- 2. Patients who may have received two or less systemic regimens (therapies include chemotherapy and/or immunotherapy)
Phase 2a Expansion Group 3a (Head and Neck): Exclusion
