Phase Ib/II, multicohort, single arm, open-label, multicenter, international clinical trial, with 6 cohorts (advanced STS, advanced L-sarcomas, other advanced sarcomas, advanced solid tumors, and localized STS) with 4 sites in Spain for phase I.

The aim of this study is to explore different infusions of PM14 (longer or repeated) in order to obtain a potentially better efficacy and similar toxicity profile in advanced soft tissue sarcoma patients as monotherapy and also in other solid tumors as concomitant treatment with radiation therapy.

Treatment

Cohort A

A phase I dose-finding stage for PM14 is planned with an estimated number of 20-25 patients. PM14 will be tested at different dose levels in 24-h IV infusion on day 1 of 21-day cycles, up to progression or unacceptable toxicity. Premedication with dexamethasone is recommended on the day before treatment initiation.

Cohort B

A phase I dose-finding stage for PM14 is planned with an estimated number of 20-25 patients. PM14 will be tested at different dose levels in 3-h IV infusion during 3 consecutive days (days 1-3) of 21-day cycles, up to progression or unacceptable toxicity. Premedication with dexamethasone is recommended on the day before treatment initiation.

Cohort E

PM14 will be administered at the recommended phase II dose (RP2D) according to the most convenient scheme. Cycles will be administered by central venous port. Premedication with dexamethasone is recommended on the day before treatment initiation. Cycles will be repeated every 21 days up to progression or unacceptable toxicity.

Cohort F

PM14 will be administered at the RP2D according to the most convenient scheme. Cycles will be administered by central venous port. Premedication with dexamethasone is recommended on the day before treatment initiation. Cycles will be repeated every 21 days up to progression or unacceptable toxicity.

Cycles will be administered by central venous port. Premedication with dexamethasone is recommended on the day before treatment initiation. Radiation therapy will start within 1 hour of PM14 infuser disconnection and will be administered with 1.8 Gy per fraction for 25 days (45 Gy in total).

Phase II: PM14 will be administered at RP2D concomitant with radiation therapy.

Cohort A and B (Phase I, PM14 monotherapy, advanced STS): 20-25 patients approximately per cohort.

Cohort E (Phase II, PM14 monotherapy, advanced L-sarcomas): 28 patients; (Simon's two-stage Minimax design), errors: α= 0.05; β=0.80, option related to efficacy = 35% (6-month PFSR) (Sample size 15+13), success in 6-month PFSR of ≤ 15% will be considered as unacceptable (H0), and would not warrant further investigation (null hypothesis). Success in 6-month PFSR of ≥ 35% will be considered as an acceptable result warranting further investigation of the investigational drug (H1, alternative hypothesis). A total of 15 eligible and treated patients will be included in the first stage of the study. If ≤ 2 successes are observed, the trial will be stopped in this cohort with the conclusion that the experimental treatment should not be further investigated. Else (≥ 3 successes), patients will continue to be accrued until 28 eligible patients enter the study. If 8 or more successes are observed in those 28 patients, it will be concluded that the results of this trial warrant further investigation.

Cohort F (Phase II, PM14 monotherapy, other advanced sarcomas): 29 patients; (Simon's two-stage Optimal design), errors: α= 0.05; β=0.80. option related to efficacy = 30% (6-month PFSR) (Sample size 10+19), success in 6-month PFSR of ≤ 10% will be considered as unacceptable (H0), and would not warrant further investigation (null hypothesis). Success in 6-month PFSR of ≥ 30% will be considered as an acceptable result warranting further investigation of the investigational drug (H1, alternative hypothesis). A total of 10 eligible and treated patients will be included in the first stage of the study. If ≤ 1 successes are observed, the trial will be stopped in this cohort with the conclusion that the experimental treatment should not be further investigated. Else (≥ 2 successes), patients will continue to be accrued until 29 eligible patients enter the study. If 6 or more successes are observed in those 29 patients, it will be concluded that the results of this trial warrant further investigation.

Success in ORR of ≥ 50% will be considered as an acceptable result warranting further investigation of the investigational drug (H1, alternative hypothesis). A total of 9 eligible and treated patients will be included in the first stage of the study. If ≤ 2 successes are observed, the trial will be stopped in this cohort with the conclusion that the investigational combination should not be further investigated. Else (≥ 3 successes), patients will continue to be accrued until 24 eligible patients enter the study. If 10 or more successes are observed in those 24 patients, it will be concluded that the results of this trial warrant further investigation.

Cohort D (Best scheme of PM14 plus RTP in localized intermediate sarcoma)

Phase I (localized sarcoma): 2 dose levels, 10 patients approximate ly. Phase II (localized "intermediate risk" STS): errors: α=0.05; β=0.80, option related to efficacy = 30% (ORR in irradiated nodules) (Sample size 10+19), success in ORR of ≤ 10% will be considered as unacceptable (H0), and would not warrant further investigation (null hypothesis).

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.

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.

PM14 Administered Intravenously to Patients With Advanced Solid Tumors

Phase I, Open-label, Dose-escalating, Clinical and Pharmacokinetic Study of PM14 Administered Intravenously to Patients With Advanced Solid Tumors

To identify the dose limiting toxicities (DLTs), and to determine the maximun tolerated dose (MTD) and the recommended dose (RD) of PM14 administered i.v. on two days (Day 1 and Day 8) or on Day 1 only, both every three weeks (q3wk) over three hours to patients with advanced solid tumors.

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.

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

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.

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.

Pharmacokinetic analyses will be evaluated in plasma and urine by standard noncompartmental analysis. Compartmental modeling may be performed if appropriate.
