PM14 Administered Intravenously to Patients With Advanced Solid Tumors
Purpose
Despite recent advances in the treatment of solid tumors in general, advanced (metastatic) disease remains mostly incurable and there is an urgent need to develop new therapeutic options for these patients, particularly investigational drugs with novel mechanisms of action. The investigation of new combination regimens of non-crossresistant agents with acceptable-and not completely overlapping-toxicities has been a major way to improve response rate and outcome of patients with advanced solid tumors.

Inclusion Criteria
- Voluntarily signed and dated written informed consent (IC), obtained prior to any specific study procedure. 2. Age ≥18 years. 3. Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤1 4. For the Dose escalation phase: Patients with pathologically confirmed diagnosis of advanced solid tumors for whom no curative standard therapy exists. For the Expansion phase: Patients with pathologically confirmed diagnosis of one of the following malignancies, for whom the standard of care therapies have failed, or are intolerant to standard of care therapies that are known to provide clinical benefit: 1. Gastrointestinal tumors: colorectal cancer, gastric cancer. 2. Sarcomas: liposarcoma, leiomyosarcoma, synovial sarcoma, Ewing's sarcoma. 3. Tumors with deleterious germline BRCA mutation: epithelial ovarian cancer (including primary peritoneal and fallopian tube cancer), breast cancer, pancreatic cancer, prostate cancer, or any other malignancies. 4. Epithelial ovarian cancer (including primary peritoneal and fallopian tube cancer) with no deleterious germline BRCA mutations or with unknown BRCA status. 5. Adrenocortical carcinoma. 5. Patients included in the Expansion phase need to meet the following requirements regarding the maximum number of prior chemotherapy regimens (no limit for biological therapies): 1. Gastrointestinal tumors: no more than three prior chemotherapy lines for colorectal cancer; and no more than two prior chemotherapy lines for gastric cancer. 2. Sarcomas: no more than two prior chemotherapy lines for liposarcoma, leiomyosarcoma and synovial sarcoma; and no more than three prior chemotherapy lines for Ewing's sarcoma. 3. Tumors with deleterious germline BRCA mutation: no more than three prior chemotherapy lines for breast cancer; and no more than two prior chemotherapy lines for prostate cancer, ovarian cancer, pancreatic cancer, gastric carcinoma, or any other malignancies. 4. Epithelial ovarian cancer with unknown BRCA status or no deleterious germline BRCA mutations: no more than three prior chemotherapy lines. 5. Adrenocortical cancer: no more than one prior chemotherapy line (excluding mitotane as single agent or associated with no chemotherapeutic agents). Note: for the purpose of this criterion, the following situations will be considered as one chemotherapy line: - Adjuvant chemotherapy; neoadjuvant chemotherapy; both adjuvant and neoadjuvant chemotherapy (except if time to relapse was >12 months, in which case it will not be considered as one line); and - Change of chemotherapy due to reasons other than PD, such as toxicity (in this case, the two lines will count as a single line). 6. Life expectancy ≥3 months. 7. Patients with measurable or non-measurable disease according to the RECIST v.1.1 are eligible during the dose escalation phase. 8. Patients included in the Expansion phase must have: 1. Measurable disease according to the RECIST v.1.1 and/or evaluable disease by serum markers in case of prostate and ovarian cancer (according to the PSAWGR and the GCIG specific criteria, respectively). 2. Confirmed progressive disease after last therapy at study entry. 9.

Laboratory values within seven days prior to first infusion: 1. ANC ≥1.5 x 10^9/L, platelet count ≥100 x 10^9/L and hemoglobin ≥9 g/dL (patients may be transfused for anemia as clinically indicated prior to study entry). 2. AST and ALT ≤3.0 x ULN. 3. Total bilirubin ≤ULN (up to 1.5 x ULN for patients with Gilbert's syndrome). 4. Creatinine clearance ≥30 mL/min (calculated using the Cockcroft and Gault's formula). 5. Serum albumin ≥3 g/dL. 11. Wash-out periods: 1. At least three weeks since the last chemotherapy (six weeks if therapy included nitrosoureas or systemic mitomycin C). 2. At least four weeks since the last monoclonal antibody (MAb)-containing therapy or curative radiotherapy (RT). 3. At least two weeks since the last biological/investigational single-agent therapy (excluding MAbs) and/or palliative RT (≤10 fractions or ≤30 Gy total dose). 4. In patients with hormone-sensitive breast cancer progressing while on hormone therapy (except for luteinizing hormone-releasing hormone (LHRH) analogues in pre-menopausal women or megestrol acetate), all other hormonal therapies must be stopped at least one week before study treatment start. 5. Castrate-resistant prostate cancer (CRPC) patients may continue receiving hormone therapy prior to and during study treatment.
Exclusion Criteria
- Concomitant diseases/conditions: 1. Increased cardiac risk: - Uncontrolled arterial hypertension despite optimal management (≥160/100 mmHg). - Presence of clinically relevant valvular disease. - History of long QT syndrome. - Corrected QT interval (QTcF, Fridericia correction) ≥450 msec on screening electrocardiogram (ECG). - History of ischemic heart disease, including myocardial infarction, angina, coronary arteriography or cardiac stress testing with findings consistent with coronary occlusion or infarction ≤6 months prior to study entry. - History of heart failure or left ventricular dysfunction (left ventricular ejection fraction [LVEF] below normal values) by multiple-gated acquisition scan (MUGA) or echocardiography (ECHO). - ECG abnormalities, including any of the following: left bundle branch block, right bundle branch block with left anterior hemiblock, second (Mobitz II) or third degree atrioventricular block. - Symptomatic arrhythmia (excluding anemia-related sinusal tachycardia grade ≤2) or any arrhythmia requiring ongoing treatment, and/or prolonged QT-QTc grade ≥2; or presence of unstable atrial fibrillation. Patients with stable atrial fibrillation on treatment are allowed provided they do not meet any other cardiac or prohibited drug exclusion criterion. - Clinically significant resting bradycardia (<50 beats per minute). - Concomitant medication with risk of inducing torsades de pointes, which cannot be discontinued or switched to an alternative drug prior to start PM14 dosing. - Use of a cardiac pacemaker. 2. Active infection requiring systemic treatment. 3. Known human immunodeficiency virus (HIV) or known hepatitis C virus (HCV) infection or active hepatitis B. 4.

Detailed Description
First-in-human, open-label, dose-finding, phase I trial, using a classical 3+3 design followed by a continual reassessment method (CRM). Patients will be included in cohorts of a minimum of three or six patients to receive PM14 at successively increasing dose levels, starting at 0.25 mg/m^2 for the Days 1 and 8 schedule. For the Day 1 schedule, the starting dose will be 4.5 mg/m^2. Dose escalation will proceed only after all the patients fully evaluable for DLT included at one dose level have completed the first cycle (i.e., three weeks). Once the RD has been determined, expansion cohorts will be included to have a minimum of 20 fully evaluable patients per indication (tumor type) treated in the Expansion phase (regardless of the schedule administered), and thus have an adequate number of patients to assess safety. The indications of these patients will be chosen depending on the efficacy data obtained during dose escalation. Patients treated at the expansion cohorts will be evaluable by the Response Evaluation Criteria in Solid Tumors (RECIST v.1.1) and/or by serum markers only in patients with prostate cancer (prostate specific-antigen [PSA]) or ovarian cancer (carbohydrate antigen-125 [CA-125]) according to the Prostate-Specific Antigen Working Group Recommendations (PSAWGR) and the Gynecologic Cancer Intergroup (GCIG) specific criteria, respectively.
