Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumor Drug: PM14 Phase 1

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.

Primary Outcome Measures :
  1. Patients with dose limiting toxicities [ Time Frame: At cycle 2 (21-days cycle) ]

  4. Overall response rate [ Time Frame: At cycle 6 (21-days cycle) ]
    To confirm the recommended dose (RD) determined during the Dose escalation phase, and to evaluate the antitumor activity of PM14 in terms of overall response rate (ORR), according to the Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1, and/or serum markers as appropriate, in patients with selected advanced solid tumors.

Secondary Outcome Measures :
  1. Clinical Benefit Rate [ Time Frame: Through study completion up to Cycle 9 ]
    Clinical benefit rate in each tumor type is defined as the percentage of patients with a confirmed response (either complete response or partial response) according to the RECIST v.1.1 and/or by serum markers or with stable disease (SD) ≥4 months

  2. Progression-free Survival [ Time Frame: From the date of first infusion of study treatment to the date of first documented progression or date of death from any cause, assessed up to 72 months ]
    Progression-free survival (PFS) is defined as the time from the date of first infusion of study treatment to the date of documented progression or death (due to any cause). If progression or death has not occurred at the time of the analysis, the PFS will be censored on the date of last tumor evaluation.

  3. Duration of Response [ Time Frame: From the date of the first documentation of response to the date of first PD or further therapy or death, assessed up to 72 months ]
    Duration of response (DoR) is defined as the time between the date of first documentation of response to the date of documented progression or death.

    Patients will be evaluable for safety if they have received at least one partial infusion of PM14. Adverse events (AEs) will be graded according to the NCI-CTCAE v.4. Additionally, treatment related discontinuations and treatment compliance (dose reduction, skipped doses and/or treatment delays due to AEs) will be described.
