Eligibility Criteria

• * Subjects ≥ 18 years at the first screening examination/visit.
• * Subjects with advanced histologically or cytologically confirmed solid tumors (see below) refractory to or relapse from at least two previous therapies.
• * Tumor types expected to express lower levels of FcRn relative to normal tissue including: STS, TNBC, cervical cancer, NSCLC, ovarian cancer, and KRAS mutated pancreatic ductal adenocarcinoma without requirement for testing FcRn level.
• * Disease that is considered measurable by RECIST v1.1.
• * Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
• * Life expectancy of at least 12 weeks.
• * Human Immunodeficiency Virus (HIV)-positive trial participants should be on established antiretroviral therapy (ART) for at least four weeks and have an HIV viral load less than 400 copies/mL prior to enrollment.
• * Left ventricular ejection fraction \> 50%.
• * Adequate organ function: (Hb ≥10 g/dL, ANC ≥1,000/µL3, and platelets
• * For patients with known Gilbert's disease, serum unconjugated bilirubin must be \< 4 mg/dL.
• * Patient must have washed out of prior chemotherapy (at least 3 weeks from last end of therapy), radiotherapy (at least 4 weeks from last end of therapy), immunotherapy (at least 4 weeks from last end of therapy), other targeted therapies (at least 4 weeks from last end of therapy), or surgery (at least 4 weeks).
• * Recovery from toxicities of prior therapy. Toxicities should have recovered to CTCAE grade ≤ 1 or baseline with exception of alopecia.
• * Females of reproductive potential must have had a negative pregnancy test performed within 7 days prior to the start of treatment. Additionally, female subjects of reproductive potential should agree to use effective acceptable forms of contraception: surgical sterilization (tubal ligation); total abstinence from sexual intercourse with the opposite sex; established hormonal birth control (e.g., oral, transdermal, injection, or implant) plus a barrier method or a double barrier method (intrauterine device, spermicide, or a diaphragm plus condom) for at least 1 month prior to Cycle 1 Day 1 and agreement to use such a method during study participation and for an additional 6 months after the last dose of SPEDOX-6.
• * For males of reproductive potential: vasectomy or highly effective contraception (e.g., condoms, abstinence) during the study and for an additional 6 months after the last dose of SPEDOX-6.
• * Patients with cancers with known driver mutations for which there are known and effective targeted therapies that have not received those therapies, but are able to. If a patient has received appropriate targeted treatment for their mutations and progressed, or those treatments are contraindicated, they will be considered potentially eligible.
• * Unstable angina pectoris, angioplasty, cardiac stenting, or myocardial infarction 6 months before study entry.
• * Untreated metastases to the Central Nervous System (CNS).
• * Have received any prior doxorubicin or anthracycline equivalent.
• * Previous radiation to the mediastinal or pericardial area.
• * A known allergy to albumin.
• * HIV infection with CD4+ count \< 350 cells/µL or Acquired Immunodeficiency (AIDS)-defining opportunistic infection in previous 12 months.
• * Pregnant (positive serum or urine pregnancy test) or lactating.
• * Previous treatment with an investigational agent or the non-approved use of a drug or device withing 4 weeks of study entry.
• * Uncontrolled diabetes mellitus.
• * Patients who require concomitant use of strong inhibitors or inducers of CYP3A4, CYP2D6 or P-glycoprotein (P-gp).
