Phase I, Multicenter, Open-label, Dose-escalating, Clinical and Pharmacokinetic Study of PM01183 in Patients With Advanced Solid Tumors

Inclusion Criteria: 1. Voluntary written informed consent of the patient obtained before any study-specific procedure. 2. Patients with histologically/cytologically confirmed diagnosis of advanced solid tumors refractory to standard therapy or for whom no standard therapy exist (excluding primary central nervous system tumors). 3. Age ≥ 18 years. 4. Patients with measurable or non-measurable disease according to RECIST. 5. Patients entered at the expansion cohort of the RD must have: * Measurable disease according to RECIST and/or, evaluable disease by serum markers in the case of prostate and ovarian cancer \[according to the Prostate-Specific Antigen Working Group Recommendations (PSAWGR) and the Gynecologic Cancer Intergroup (GCIG) specific criteria, respectively\]. * Confirmed progressive disease after last therapy, before study initiation. * Available tumor samples (if pharmacogenomic study consented). 6. Recovery from any drug-related adverse event derived from any previous treatment, excluding alopecia and grade ≤ 1 asymptomatic peripheral neuropathy according to the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v.3.0. 7. Laboratory values within seven days prior to first infusion: * Platelet count ≥ 100 x109/l, hemoglobin \> 9 g/dl (patients can be transfused as clinically indicated prior to study entry) and absolute neutrophils count (ANC) ≥ 1.5 x109/l. * Alkaline phosphatase ≤ 2.5 x the upper limit of normality (ULN) * Aspartate aminotransferase (AST) ≤ 2.5 x ULN. * Alanine aminotransferase (ALT) ≤ 2.5 x ULN. * Total bilirubin ≤ ULN. f) Calculated creatinine clearance: ≥ 40 ml/min (calculated using the Cockcroft and Gault formula). * Albumin ≥ 2.5 g/dl. * Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2. 8. Women of childbearing potential must have a negative serum pregnancy test before study entry. Both men and women must agree to use a medically acceptable method of contraception throughout the treatment period and for 6 months after discontinuation of treatment. Acceptable methods of contraception include: intrauterine conceptive device (IUD), oral contraceptives, subdermal implant and double barrier (condom with a contraceptive sponge or contraceptive suppository). Exclusion Criteria: 1. Pregnant or lactating women. 2. Less than three weeks from radiation therapy (six weeks in case of extensive prior radiotherapy) or last dose of hormonal therapy, biological therapy or chemotherapy (six weeks in case of nitrosoureas, mitomycin C, trastuzumab, bicalutamide or high-dose chemotherapy). 3. Evidence of progressive Central Nervous System (CNS) metastases or any symptomatic brain or leptomeningeal metastases. 4. Patients for whom non-standard surgery approach may result in tumor free survival or significant palliation. 5. Other relevant diseases or adverse clinical conditions: * Increased cardiac risk: symptomatic and/or medication requiring congestive heart failure or clinically relevant valvular heart disease or unstable angor pectoris or myocardial infarction within 12 months before inclusion in the study, or ≥ grade 1 arrhythmia or any grade requiring treatment, or uncontrolled arterial hypertension (≥ 160/100 mmHg) despite optimal medical therapy. * History of significant neurological or psychiatric disorders. * Active infection. * Significant non-neoplastic liver disease (e.g., cirrhosis, active chronic hepatitis). * Immunocompromised patients, including those known to be infected by human immunodeficiency virus (HIV). * Any other major illness that, in the investigator's judgment, will substantially increase the risk associated with the patient's participation in this study. 6. Limitation of the patient's ability to comply with the treatment or to follow-up at a participating protocol. Patients registered on this trial must be treated and followed at a participating center. 7. Prior treatment with any investigational product in the period ≥ 5 half-lives of the investigational compound prior to the first infusion. 8. Known hypersensitivity to any of the components of the drug product.
