Eligibility Criteria:
Inclusion Criteria:

1. Age ≥ 18 years, male or female.
2. Histologically or cytologically confirmed malignant solid tumor that has relapsed or is refractory to standard therapy or no standard chemotherapy exists.
3. Capable of providing informed consent and complying with trial procedures.
4. Baseline absolute left ventricular ejection fraction (LVEF) measured scintigraphically (MUGA, myocardial scintigram) or by ultrasound (echocardiogram) ≥ Institutional Lower Limit of Normal.
5. Eastern Cooperative Oncology Group performance status (ECOG PS) 0-2.
6. Life expectancy \> 12 weeks.
7. Measurable or evaluable disease according to RECIST 1.1 criteria.15
8. Women must not be able to become pregnant (e.g., post-menopausal for at least 1 year, surgically sterile, or practicing adequate birth control methods) for the duration of the study. \[Adequate contraception includes: oral contraception, implanted contraception, intrauterine device implanted for at least 3 months, or barrier method in conjunction with spermicide.\]
9. Women of child bearing potential must have a negative serum or urine pregnancy test at the Screening Visit and be non-lactating.
10. Geographic accessibility to the site that ensures that the subject will be able to keep all study-related appointments.

Exclusion Criteria:

1. Palliative surgery, chemotherapy, immunotherapy and/or radiation treatment \< 4 weeks prior to the Screening Visit.
2. Prior treatment with ≥ 150 mg/m2 doxorubicin HCl or Doxil® cumulative dose, or epirubicin ≥ 150 mg/m2.
3. Exposure to any investigational agent within 30 days of Randomization.
4. Evidence of active or uncontrolled central nervous system (CNS) metastasis (negative imaging study performed due to suspicion of CNS metastasis within 4 weeks of Screening Visit).
5. History of other malignancies except cured basal cell carcinoma, squamous cell carcinoma, superficial bladder cancer or carcinoma in situ of the cervix.
6. Laboratory values: Screening serum creatinine ≥ 2 times the upper limit of normal (ULN), alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \> 2 times the ULN if no liver metastases or 5 times the ULN if liver metastases, total bilirubin \> 2 times the ULN, white blood cell (WBC) count \< 3500/mm3, or absolute neutrophil count (ANC) \< 1500/mm3, platelet concentration \< 100,000/mm3, hematocrit level \< 25% for females or \< 27% for males, or coagulation tests (prothrombin time \[PT\]; partial thromboplastin time \[PTT\]), International Normalized Ration (INR) \> 1.5 times the ULN, serum albumin \< 2.0g/dL.
7. Clinically evident congestive heart failure (CHF) \> class II of the New York Heart Association (NYHA) guidelines.
8. Baseline QTc \> 470 msec and/or previous history of QT prolongation while taking other medications. Concomitant use of medications associated with a high incidence of QTc prolongation is not allowed.
9. Serious clinically significant cardiac arrhythmias, defined as the existence of an absolute arrhythmia or ventricular arrhythmias classified as Lown III, IV or V.
10. History or signs of active coronary artery disease with or without angina pectoris.
