Brief Summary:
Prospective, open-label, uncontrolled and multicenter phase I-II study in SCLC patients with ECOG PS 0-1 who have failed one prior platinum-containing line but no more than one chemotherapy-containing line. The study will be divided into two parts: a dose-ranging phase I with escalating doses of PM01183 in combination with a fixed dose of atezolizumab, followed by a single-arm phase II part with expansion at the RD determined during the phase I.

Condition or disease Intervention/treatment Phase
Carcinoma, Small Cell Lung Drug: PM 01183 Drug: Atezolizumab Phase 1

Detailed Description:

Phase I Patients will receive atezolizumab at a fixed dose of 1200 mg intravenously (i.v.) followed by PM01183 at a starting dose of 2.5 mg/m2 i.v. as a 1-hour infusion on Day 1 every three weeks (q3wk). PM01183 doses will be escalated in successive cohorts of patients following a modified Fibonacci scheme and a classical 3+3 design, and according to observed tolerance and safety.

To determine the maximum tolerated dose (MTD) and the recommended dose for phase II studies (RD) of PM01183 in combination with atezolizumab in advanced SCLC patients progressing after platinum doublet chemotherapy.

Arm Intervention/treatment
Experimental: PM01183 w/ Atezolizumab
Patients will receive atezolizumab at a fixed dose of 1200 mg intravenously (i.v.) as a 60-minute infusion (the second and subsequent infusions may be administered over 30 minutes) followed by PM01183 at a starting dose of 2.5 mg/m2 i.v. as a 1-hour infusion on Day 1 every three weeks (q3wk). Following analysis of cohorts, dose levels can be escalated from 2.5mg to 3.2, to a maximum dose of 3.5 mg of PM01183
Drug: PM 01183
Lyophilisate for solution for infusion
Other Name: Lurbinectidin

Drug: Atezolizumab
Concentrate for solution for infusion
Other Name: Tecentriq




Primary Outcome Measures :
  1. Determination of Maximum Tolerable Dose [ Time Frame: one cycle - 21 days ]
    The MTD will be the lowest dose level explored during dose escalation at which more than one third of evaluable patients experience a DLT during Cycle 1.

  2. Determination Recomended Dose: [ Time Frame: one cycle - 21 days ]
    The RD will be the highest dose level explored during dose escalation at which less than one third of evaluable patients experience a DLT during Cycle 1.


Secondary Outcome Measures :
  1. Progression-free survival [ Time Frame: the time from the date of registration to the date of documented progression per RECIST v.1.1 or death, assessed approximately up to 30 months ]
    the time from the date of registration to the date of documented progression per RECIST v.1.1 or death. If the patient receives further antitumor therapy or is lost to follow-up before PD, PFS will be censored at the date of last tumor assessment before the date of subsequent antitumor therapy.

  2. Duration of response [ Time Frame: from the date of first documentation of response per RECIST v.1.1 (complete or partial response, whichever comes first) to the date of documented PD or death, assessed approximately up to 30 months ]
    Duration of response will be calculated from the date of first documentation of response per RECIST v.1.1 (complete or partial response, whichever comes first) to the date of documented PD or death. The censoring rules defined above for PFS will be used for DoR.

  3. Clinical benefit [ Time Frame: ≥3 months ]
    defined as percentage of evaluable patient with complete response, partial response or stable disease lasting ≥3 months, as defined by RECIST v1.1.

  4. Overall survival [ Time Frame: from the date of registration to the date of death or last contact; approximately 30 months ]
    calculated from the date of registration to the date of death (death event) or last contact (in this case, survival will be censored on that date).

  5. Mid- and long-term survival [ Time Frame: 12, 18 and 24 months ]
    will be the Kaplan-Meier estimates of the probability of being alive at these time points

  6. Pharmacokinetics measures - plasma concentration [ Time Frame: 8 days ]
    PK parameters will be evaluated in plasma by standard non-compartmental methods (compartmental modeling may be performed if appropriate).The dose-exposure relationships for maximum plasma concentration (Cmax) and any potential PK interaction of atezolizumab over PM01183 will be explored.

  7. Pharmacogenetics measurements of genes implicated in the metabolism and/or transport of PM01183 [ Time Frame: 1 day ]
    In order to explore factors that may help explain individual variability in the main PK parameters, the presence or absence of germline mutations or polymorphisms in genes that may be involved in the metabolism and/or transport of PM01183 will be analyzed in leukocyte DNA extracted from one blood sample (10 mL) obtained at any time during the study, but preferably just before treatment start in Cycle 1 along with the first PK sample

  8. Pharmacogenomics measurements of predictive/prognostic markers of response and/or resistance to PM01183 and atezolizumab [ Time Frame: 1 day ]

    In order to determine predictive/prognostic markers of response and/or resistance to PM01183 and atezolizumab, tumor samples available at baseline will be evaluated in all patients.

    the biomarker to analize are: PD-L1 and PD-L2 expression in tumor cells and in tumor-infiltrating immune cells, presence of CD8+ T cell and CD4+ T cell in stromal-tumor edge and inside the tumor parenchyma, tumor-infiltrating lymphocyte (TIL) density, expression of granzyme B, the activated transcription factor signal transducer and activator of transcription 1 (pSTAT1), Ki67, interferon gamma (IFNƔ), tumor necrosis factor alpha (TNF-α), cytotoxic T-lymphocyte-associated protein 4 (CTLA4), fractalkine, lymphocyte-activation gene 3 (LAG-3) and T-cell immunoglobulin and mucin protein 3 (TIM-3) by IHC;

    and Tumor mutational burden by DNAseq with Foundation One (or another similar validated panel).


  9. Pharmacogenomics measures sub-study - tumor samples [ Time Frame: one sample between 4th to 6th weeks after treatment onset ]

    For tumor biomarkers research, tumor samples will be collected on-treatment to be analyzed at the end of the study. The on-treatment biopsy will be optional, requiring specific patient consent.

    The on-treatment tumor samples will be compared to baseline tumor samples and the biomarker to analize are:

    PD-L1 and PD-L2 expression in tumor cells and in tumor-infiltrating immune cells, presence of CD8+ T cell and CD4+ T cell in stromal-tumor edge and inside the tumor parenchyma, tumor-infiltrating lymphocyte (TIL) density, expression of granzyme B, the activated transcription factor signal transducer and activator of transcription 1 (pSTAT1), Ki67, interferon gamma (IFNƔ), tumor necrosis factor alpha (TNF-α), cytotoxic T-lymphocyte-associated protein 4 (CTLA4), fractalkine, lymphocyte-activation gene 3 (LAG-3) and T-cell immunoglobulin and mucin protein 3 (TIM-3) by IHC;

    and Tumor mutational burden by DNAseq with Foundation One (or another similar validated panel).


  10. Pharmacokinetics measures - area under the curve [ Time Frame: 8 days ]
    PK parameters will be evaluated in plasma by standard non-compartmental methods (compartmental modeling may be performed if appropriate).The area under the curve (AUC) will be evaluated, and any potential PK interaction of atezolizumab over PM01183 will be explored.

  11. Pharmacogenomics measures sub-study - blood samples [ Time Frame: First day of each cycle (each cycle is 21 days) and at the End of Treatment visit, which is up to 37 days after the last study treatment administration ]

    For those patients specifically consenting, blood samples for the evaluation of biomarkers will be drawn just before treatment on Day 1 of each cycle and at EOT.

    The biomarker to analize are:

    • Plasma cytokine analysis by enzyme-linked immunosorbent assay (ELISA): IFNƔ, TNF-α, interleukins IL-1β, IL-6 and IL-18, and CXCL11 (ITAC).
