Study Summary
The first part of the study (phase Ia - dose escalation) will evaluate the safety and tolerability and identify the dose-limiting toxicities (DLTs) of PM54.
The second part of the study (phase Ib - expansion) will be to evaluate the antitumor activity of PM54 in terms of clinical benefit (response or stable disease [SD] ≥4 months associated with tumor shrinkage), according to the RECIST v.1.1 (or modified RECIST [mRECIST] v.1.1 in case of malignant pleural mesothelioma [MPM]) and/or serum markers as appropriate, in patients with selected advanced solid tumors.
Medical Condition
The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.
Phase
The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

- Note: patients with measurable or non-measurable disease according to the Response Evaluation Criteria In Solid Tumors (RECIST) v.1.1 (or mRECIST v.1.1 in case of MPM) are eligible during this stage.
- No more than three prior lines of chemotherapy.
- Phase Ib (safety run-in and expansion) stage: patients must have:
- Pathologically confirmed diagnosis of one of the following:
- Extrapulmonary small cell carcinoma) or poorly differentiated grade 3 gastroenteropancreatic NEC with Ki67 index ≥55%.
- Cutaneous melanoma.
- Malignant pleural mesothelioma (MPM).
- Endometrial adenocarcinoma (Note: carcinosarcomas are not allowed).
- Synovial sarcoma
- Measurable disease according to the RECIST v.1.1 (or mRECIST v.1.1 in case of MPM) and/or evaluable disease byserum markers in case of prostate and ovarian cancer (according to the Prostate-Specific Antigen Working Group Recommendations (PSAWGR) and the Gynecologic Cancer Intergroup (GCIG) specific criteria, respectively).
- Progressive disease after last therapy at study entry.
- Patients must have received standard treatments:
- Extrapulomnary small cell carcinoma/ gastroenteropancreatic NEC: no more than two prior lines of chemotherapy.
- Cutaneous melanoma:
- BRAF wild-type (WT) melanoma: at least one prior line of immunotherapy for advanced disease. The patient may have received this therapy in the adjuvant setting. No more than two prior lines of systemic therapy for advanced disease. Note: patients with disease progression during adjuvant therapy or within the first six months after the last dose of adjuvant therapy will be considered as having been treated with one prior line of treatment.
- BRAF-mutated melanoma: at least one prior line of target therapy for advanced disease with BRAF inhibitor with or without MEK-inhibitor, and at least one prior line of immunotherapy for advanced disease. The patient may have received any of these therapies in the adjuvant setting. No more than three prior lines of systemic therapy for advanced disease.
- Malignant pleural mesothelioma (MPM): no more than two prior lines of therapy; one of them should be a platinum containing line. Patients with non-epithelioid MPM should have received a prior immunotherapy line.
- Endometrial adenocarcinoma: no more than two prior lines of chemotherapy for metastatic disease. In addition, regardless of setting, patients must have received one prior platinum-containing regimen.
- Synovial sarcoma: at least one but no more than two prior lines of chemotherapy.
- Recovery to grade ≤1 from drug-related AEs of previous treatments, excluding grade 2 alopecia, according to the NCI-CTCAE v.5.
- Laboratory values within seven days prior to first infusion:
- Absolute Neutrophil Count (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).
- Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) ≤3.0 x ULN.
- Total bilirubin ≤upper limit of normal (ULN) (up to 1.5 x ULN for patients with Gilbert's syndrome).
- Creatinine clearance ≥30 mL/min (calculated using the Cockcroft and Gault's formula).
- Serum albumin ≥3 g/dL. *
- Creatine phosphokinase (CPK) ≤ 2.5 x ULN.
- Washout periods:
- At least three weeks since the last chemotherapy.
- At least four weeks since the last monoclonal antibody (MAb)-containing therapy.
- At least two weeks since the last biological/investigational single-agent therapy (excluding MAbs) and/or palliative radiotherapy (RT).
