(RECIST) v.1.1.
For patients with glioblastoma: Measurable disease according to RECIST v.1.1 and
RANO criteria.
2. Documented disease progression per RECIST v.1.1 during or immediately after last
therapy according to any of the aforementioned criteria.
For patients with glioblastoma: Documented disease progression per RECIST v.1.1 and
RANO criteria.
8. At least three weeks since the last anticancer therapy (excluding immunotherapy that
must be at least two weeks, provided that is not combined with chemotherapy),
including investigational drugs and radiotherapy, and at least six weeks since
nitrosoureas and mitomycin C (systemic).
For patients with glioblastoma: at least 12 weeks since the end of radiotherapy,
except if:
1. The patient has a new lesion outside of the radiotherapy field, or
2. The patient has undergone brain surgery to remove the tumor before study entry,
and progressive disease has been confirmed histologically.
9. Adequate bone marrow, renal, hepatic, and metabolic function (assessed ≤ 7 days before
inclusion in the study):
1. Platelet count ≥ 100 × 10^9/L, hemoglobin ≥ 9.0 g/dL and absolute neutrophil
count (ANC) ≥ 2.0 × 10^9/L.
2. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3.0 × the
upper limit of normal (ULN), even in the presence of liver metastases.
3. Alkaline phosphatase (ALP) ≤ 2.5 × ULN (≤ 5 × ULN if disease-related/in the case
of liver metastases).
4. Total bilirubin ≤ 1.5 × ULN or direct bilirubin ≤ ULN.
5. International Normalized Ratio (INR) < 1.5 (except if patient is on oral
anticoagulation therapy).
6. Calculated creatinine clearance (CrCL) ≥ 30 mL/minute (using Cockcroft-Gault
formula).
7. Creatine phosphokinase (CPK) ≤ 2.5 × ULN.
8. Albumin ≥ 3.0 g/dL(*).
10. Recovery to grade ≤ 1 or to baseline from any adverse event (AE) derived from previous
treatment (excluding alopecia and/or cutaneous toxicity and/or peripheral neuropathy
and/or fatigue grade ≤ 2).
(*)Albumin transfusion to increase the blood level in order to fulfill the inclusion
criterion is strictly forbidden.
Exclusion Criteria:
1. Concomitant diseases/conditions:
1. History or presence of unstable angina, myocardial infarction, congestive heart
failure, or clinically significant valvular heart disease within the previous
year.
2. Symptomatic arrhythmia or any uncontrolled arrhythmia requiring ongoing
treatment.
3. Myopathy or any clinical situation that causes significant and persistent
elevation of CPK (> 2.5 × ULN in two different determinations performed one week
apart).
4. Ongoing chronic alcohol consumption or cirrhosis with Child-Pugh score B or C.
Known Gilbert disease.
5. Active uncontrolled infection.
6. Known human immunodeficiency virus (HIV) infection. Known human immunodeficiency
virus (HIV) or known hepatitis C virus (HCV) infection or active hepatitis B.
7. Any past or present chronic inflammatory colon and/or liver disease, past
intestinal obstruction, pseudo or sub-occlusion or paralysis.
8. Evident symptomatic pulmonary fibrosis or interstitial pneumonitis, pleural or
cardiac effusion rapidly increasing and/or necessitating prompt local treatment
within seven days.
9. Any other major illness that, in the Investigator's judgment, will substantially
increase the risk associated with the patient's participation in this study.
2. Prior treatment with PM01183, trabectedin (Yondelis®) or topoisomerase I inhibitors
(irinotecan, topotecan, etc.). Prior topoisomerase inhibitors (e.g., irinotecan) are
only allowed in patients with colorectal carcinoma.
3. Prior bone marrow or stem cell transplantation, or radiation therapy in more than 35%
of bone marrow.
4. Known brain metastases or leptomeningeal disease involvement. Glioblastoma lesions
(primary or locally advanced) are eligible. In SCLC, patients with brain metastases or
leptomeningeal disease involvement are eligible provided they are radiologically
stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging
(note that the repeat imaging should be performed during study screening), clinically
stable and without requirement of steroid treatment (patients taking steroids in the
process of already being tapered within two weeks prior to screening are allowed).
Brain CT-scan or MRI results must be provided at baseline.
5. Women who are pregnant or breast feeding and fertile patients (men and women) who are
not using an effective method of contraception.(*)
6. Limitation of the patient's ability to comply with the treatment or follow-up
protocol.
(*)Women of childbearing potential (WOCBP) must agree to use an effective contraception
method to avoid pregnancy during the course of the trial (and for at least three months
after the last infusion). Fertile male patients must agree to refrain from fathering a
child or donating sperm during the trial and for four months after the last infusion.
