At least one measurable lesion (target lesion according to the RECIST v.1.1), located in a non-irradiated area and adequately measured less than four weeks before study entry. Tumors within a previously irradiated field will be designated as non-target lesions unless progression is clearly documented or biopsy proven. 10. Absolute neutrophil count (ANC) ≥ 1.5 x 109/l; platelet count ≥ 100 x 109/l, and hemoglobin ≥ 9 g/dl. 11. Adequate renal function: calculated creatinine clearance (using Cockcroft and Gault's formula) ≥ 30 ml/min. 12. Adequate hepatic function: * Total bilirubin ≤ 1.5 x upper limit or normality (ULN), unless due to Gilbert's syndrome. * Alanine aminotransferase (ALT), aspartate aminotransferase (AST) ≤ 3 x ULN (≤ 5 x ULN in case of hepatic metastases), and alkaline phosphatase (AP) ≤ 2.5 x ULN (≤ 5 x ULN in case of extensive bone involvement). * Albumin ≥ 25 g/l. 13. Left ventricular ejection fraction (LVEF) within normal limits (LVEF of at least 50%). 14. Women of childbearing potential must have a negative serum pregnancy test before study entry. Both women and men must agree to use a medically acceptable method of contraception throughout the treatment period and for three months after discontinuation of treatment. Acceptable methods of contraception include complete abstinence, intrauterine device (IUD), oral contraceptive, subdermal implant and double barrier (condom with a contraceptive sponge or contraceptive suppository).

Any other major illness that, in the Investigator's judgment, will substantially increase the risk associated with the patient's participation in the study. The Investigator should feel free to consult the Study Coordinator or the Sponsor(s) in case of uncertainty in this regard. 9. Limitation of the patient's ability to comply with the treatment or to follow-up at a participating center.

Recruitment details
A total of 17 patients were included and 16 of them were treated with PM00104 at five investigational sites from the USA (n=3), France and Italy. The patients participated in this study between 22 December 2010 (first consent) and 21 May 2012 (last follow-up). First and last doses were administered on 4 January 2011 and 24 January 2012, respectively

A treatment cycle consisted of PM00104 administration on Days 1, 8 and 15, plus one week of follow-up. Study evaluations had to be completed during each cycle prior to subsequent PM00104 infusion. Treatment cycles were repeated every four weeks | 17 |
