Phase I Multicenter, Open-label, Clinical and Pharmacokinetic Study of Plitidepsin in Combination With Sorafenib or Gemcitabine in Patients With Advanced Solid Tumors or Lymphomas

Phase I Multicenter, Open-label, Clinical and Pharmacokinetic Study of Plitidepsin in
Combination with Sorafenib or Gemcitabine in Patients with Advanced Solid Tumors or
Lymphomas to determine the maximum tolerated dose (MTD) and the recommended dose (RD), the
pharmacokinetics (PK) of these combinations, drug-drug PK interactions, preliminary
information on the clinical antitumor activity of these combinations in solid tumors,perform
a preliminary pharmacogenomic (PGx) study of potential biomarkers of sensitivity/resistance
to these drugs combinations and of prognostic markers of the treatment outcome in tumor
tissue sample.

Inclusion Criteria:

- Age ≥ 18 years

- ECOG performance status (PS) of ≤ 1

- Life expectancy ≥ 3 months

- Patients with histologically/cytologically confirmed diagnosis of advanced solid
tumors or lymphomas (excluding B-cell derived lineage and/or primary cutaneous and/or
leukemic disease) refractory to standard therapy and with reasonable chance to
benefit from any of these combinations according to the investigator's opinion.

- Patients entered at the expansion cohort of the RD must have: a) measurable disease
according to RECIST, or to International Working Group Criteria (IWC) for lymphoma
patients or b) Evaluable disease by serum markers in the case of prostate and ovarian
cancer (according to Prostate-Specific Antigen Working Group Recommendations (PSAWGR)
and Gynecologic Cancer Intergroup (GCIG) specific criteria, respectively

- At least 4 weeks since last chemotherapy (6 weeks since nitrosoureas and mitomycin
C), immunotherapy or any other pharmacological treatment and radiotherapy. In the
case of hormone-sensitive cancer progressing while on hormone therapy (i.e., breast,
prostate cancer), hormone therapy must be either stopped 4 weeks before or continued
during the trial

- Adequate bone marrow, renal, hepatic, and metabolic function (assessed ≤ 7 days
before inclusion in the study): a) Platelet count ≥100 x109/L (≥ 75 x 109/L for
lymphoma patients), hemoglobin ≥9.0 g/dL (≥ 8.0 g/dL for lymphoma patients) and
absolute neutrophil count (ANC) ≥1.5 x109/L (≥1.0 x109/L for lymphoma patients). b)
Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT): ≤ 3.0 x the
upper limit of normal (ULN), independently of the presence of liver metastases. c) AP
≤2.5 x ULN (≤5 x ULN in case of extensive bone metastases). d) Total bilirubin ≤1.5 x
ULN (unless due to indirect hyperbilirubinemia for the gemcitabine combination arm
only). e) Calculated CrCl: ≥ 40 mL/minute (by means of Crockroft and Gault´s
formula). f) CPK ≤ 2.5 x ULN. g) Albumin ≥2.5 g/dL. h) Troponin I ≤ULN

- Recovery to grade ≤1 from any AE derived from previous treatment (excluding alopecia
of any grade and peripheral neuropathy ≤ grade 2)

- LVEF by ECHO or MUGA above the lower normal limit.

- 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 3 months after discontinuation
of treatment. Acceptable methods of contraception include complete abstinence,
intrauterine device (IUD), oral contraceptive, subdermal implant and double barrier

- Voluntarily signed and dated written informed consent prior to any specific study

Exclusion Criteria:

- Previous treatment with any of the study drugs (in the expansion cohort at the RD).

- Concomitant diseases/conditions:

- History or presence of unstable angina, myocardial infarction, valvular heart
disease or congestive heart failure.

- Previous mediastinal radiotherapy.

- Previous treatment with doxorubicin at cumulative doses in excess of 450 mg/m2

- Symptomatic arrhythmia or any arrhythmia requiring ongoing treatment, and/or
prolonged QT-QTc > to grade 1.

- Active uncontrolled infection.

- Myopathy or any clinical situation that causes significant and persistent
elevation of CPK (>2.5 x ULN in two different determinations performed with one
week apart).

- Limitation of the patient's ability to comply with the treatment or follow-up

- Any other major illness that, in the Investigator's judgment, will substantially
increase the risk associated with the patient's participation in this study.

- Peripheral neuropathy >grade 2

- Symptomatic, progressive or requiring-corticosteroids documented brain metastases or
leptomeningeal disease. Controlled and stable brain metastases without steroids are

- Men or women of childbearing potential who are not using an effective method of
contraception as previously described; women who are pregnant or breast feeding

- Patients who have had radiation therapy in greater than 35% of the bone marrow

- History of previous bone marrow and/or stem cell transplantation. (Not for patients
treated at RD in the expansion cohort)

- High transfusional requirements (> 2 packages of red blood cells and/or 1 platelets
transfusion) in the 30 days prior to inclusion in the study

- Participation in another clinical trial or concomitant treatment with any
investigational product in the 30-day period prior to inclusion in the study.

- For sorafenib treatment only: a) Hypersensitivity to sorafenib or any component of
the formulation. b) Need of chronic exposure to antacids, H-2 antagonists or
proton-pump inhibitors. c) Current need for anticoagulation treatment (including low
dose warfarin and LMWH treatment at full anticoagulant doses).

- Abnormal thyroid function [as per normal serum thyroid stimulating hormone (TSH)
within 14 days of first dose of study treatment).

- Uncontrolled arterial hypertension (≥160/100) despite optimal medical therapy.

- Child-Pugh grade C hepatic cirrhosis of any cause

- For gemcitabine treatment only:

- Hypersensitivity to gemcitabine or any component of the formulation.

- Impending need for palliative radiotherapy to ameliorate painful metastases.
