Registered outcomes13

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryOverall Response Rate (ORR)2 years
The primary endpoint is Overall Response Rate (ORR) of chemotherapy, defined as the percentage of patients experiencing partial response (PR) or complete response (CR), according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, after starting the treatment with FTD/TPI plus Bevacizumab.
SecondaryProgression free survival (PFS)2 years
Measured as the time from the start of the treatment with FTD/TPI plus Bevacizumab to the date of first progression, or the date of death from any cause, or the date of the last restaging in non-progressed patients
SecondarySafety evaluation2 years
All adverse events will be recorded during the observation period (i.e. from the day of the first DC vaccine dose administered in the induction phase up to 30 days after the last dose of chemotherapy), will be reported and graded according to NCI CTCAE 5.0.
SecondaryOverall Survival (OS)2 yearsMeasured from the start of the induction treatment until the date of death from any cause or the last date on which it was known that the patient was alive.
SecondaryIn vivo immunomonitoring through DTH test:2 years
In vivo immunomonitoring through DTH test: DTH testing will be performed in all patients on day 0 (pre-treatment DTH), after the induction phase (post-combo immuno treatment DTH), after the maintenance phase, at the end of treatment and at disease progression. The diameter of induration/erythema observed after 24 hours is recorded according to the following scale: 0-5 mm grade 1, 6-10 mm grade 2, 11-20 mm grade 3, and \> 21 mm grade 4. As DTH reactivity to lower concentrations of the antigen(s) is strictly related to more intense antigen specific immune responses, score results will be normalized against the concentration itself and transformed into a 0-80 scale for analysis purposes. Best results obtained for each patient at any of the posttreatment DTHs, either for tumor homogenate or keyhole limpet hemocyanin (KLH), will be taken into account for data analysis (best normalized score).
SecondaryCharacterization of patient's HLA class I immune response2 years
The typing of the locus A-B-C-DR and DQA/DQB will be performed by the Genetic Laboratory by means of the sequence-specific oligonucleotide probe reverse hybridization (PCR-SSO) method. This information will be used to design patient's HLA restricted peptides for personalized functional in vitro immune assays (such as IFN-γ ELISPOT assay and INF-γ secretion assay), as well as for tetramer-guided peripheral monitoring of the antigen specific response. Moreover, statistical analysis will be conducted to correlate the strength of the recorded immunological response to the full HLA haplotype and the clinical outcome.
SecondaryCharacterization of patient's HLA class II immune response2 years
The typing of the locus A-B-C-DR and DQA/DQB will be performed by the Genetic Laboratory by means of the sequence-specific oligonucleotide probe reverse hybridization (PCR-SSO) method. This information will be used to design patient's HLA restricted peptides for personalized functional in vitro immune assays (such as IFN-γ ELISPOT assay and INF-γ secretion assay), as well as for tetramer-guided peripheral monitoring of the antigen specific response. Moreover, statistical analysis will be conducted to correlate the strength of the recorded immunological response to the full HLA haplotype and the clinical outcome.
SecondaryCharacterization of patient's HLA-restricted immune response2 years
The typing of the locus A-B-C-DR and DQA/DQB will be performed by the Genetic Laboratory by means of the sequence-specific oligonucleotide probe reverse hybridization (PCR-SSO) method. This information will be used to design patient's HLA restricted peptides for personalized functional in vitro immune assays (such as IFN-γ ELISPOT assay and INF-γ secretion assay), as well as for tetramer-guided peripheral monitoring of the antigen specific response. Moreover, statistical analysis will be conducted to correlate the strength of the recorded immunological response to the full HLA haplotype and the clinical outcome.
SecondaryDefinition of the prognostic and predictive role of peripheral immune cell subsets and soluble factors2 years
Definition of the prognostic and predictive role of peripheral immune cell subsets and soluble factors: PBMC samples taken before treatment, during and after treatment will be evaluated by multiparametric flow cytometry to assess abundance of regulatory cell subsets (regulatory T cells and immunosuppressive myeloid cells). Moreover, an automated platform of multianalyte will be applied in longitudinal plasma samples. Results will be analyzed by means of bioinformatics and statistical tools and correlated with all the relevant clinical parameters.
SecondaryIn situ characterization of pMMR mCRC through Next Generation Sequencing analysis2 years
NGS approaches (WES and RNAseq analysis) together with in house available bioinformatics pipeline will be used to score the antigen/neoantigen expression in pre-treatment and, whenever available, post-treatment tissue. Deconvolution methods will be used to enumerate immune cells abundance from transcriptional data. Moreover, expression of other TME-related transcripts will be addressed and correlated to the clinical outcome.
