Study of BO-112 With Pembrolizumab for Colorectal or Gastric/GEJ Cancer With Liver Metastasis

ABSTRACT: This is an open, single arm, multicenter phase 2 trial in which BO-112 will be administered intratumorally in combination with intravenous pembrolizumab in patients with liver metastasis from colorectal, gastric or gastroesophageal junction cancers. The objective is to reverse the primary resistance that a subgroup of patients from these tumors having microsatellite stability present to the PD-1 inhibitors. Treatment will be administered every 3 weeks, with the exception of the first cycle, in which BO-112 will be also administered on D8, for up to 2 years. The primary objective is overall response rate based on RECIST 1.1 and safety, specifically referred to treatment emergent adverse events (TEAEs) with severity ≥ Grade 3 related to the study treatment (NCI-CTCAE v 5.0). The secondary endpoints include other efficacy endpoints (duration of response, disease control rate, progression-free survival, overall survival at 6 months, all based on RECIST 1.1, and overall response rate based on a specific tumor assessment criteria to evaluate the response to immunotherapies, IRECIST) and safety, in this case considering the number and proportion of subjects with treatment TEAEs (any grade) . In addition, the changes in the tumor microenvironment induced by the injection of BO-112 will be also evaluated as exploratory endpoints.

Differential T-cell and monocyte responses in hepatocellular carcinoma treated with regorafenib plus nivolumab: an integrated clinical and biomarker analysis of the phase 2 RENOBATE trial

Project description:Regorafenib has anti-tumor activity in patients with unresectable hepatocellular carcinoma (uHCC) with potential immunomodulatory effects, suggesting that its combination with immune checkpoint inhibitor may have clinically meaningful benefits in patients with uHCC. The multicenter, single-arm, phase 2 RENOBATE trial tested regorafenib-nivolumab as front-line treatment for uHCC. Forty-two patients received nivolumab 480 mg every 4 weeks and regorafenib 80 mg daily (3-weeks-on/1-week-off schedule). The primary endpoint was the investigator-assessed objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. The secondary endpoints included safety, progression-free survival (PFS) and overall survival (OS). ORR per RECIST version 1.1 was 31.0%, meeting the primary endpoint. The most common adverse events were palmar-plantar erythrodysesthesia syndrome (38.1%), alopecia (26.2%) and skin rash (23.8%). Median PFS was 7.38 months. The 1-year OS rate was 80.5%, and the median OS was not reached. Exploratory single-cell RNA sequencing analyses of peripheral blood mononuclear cells showed that long-term responders exhibited T cell receptor repertoire diversification, enrichment of genes representing immunotherapy responsiveness in MKI67+ proliferating CD8+ T cells and a higher probability of M1-directed monocyte polarization. Our data support further clinical development of the regorafenib-nivolumab combination as front-line treatment for uHCC and provide preliminary insights on immune biomarkers of response. ClinicalTrials.gov identifier: NCT04310709 .

FOLFOXIRI plus Panitumumab or FOLFOX plus Panitumumab in the treatment of metastatic colorectal cancer.

Project description:Primary objectives: compare the activity of panitumumab in combination with mFOLFOX6 or with mFOLFOXIRI in RAS and BRAF wt mCRC patients in terms of Overall Response Rate according to RECIST version 1.1 Primary endpoints: Distribution of overall response rate (ORR)ORR is defined as the percentage of patients, relative to the total of enrolled subjects, achieving a complete (CR) or partial (PR) response, according to RECIST 1.1 criteria, during the induction and the maintenance phases of treatment. The determination of clinical response will be based on investigator reported measurements. Responses will be evaluated every 8 weeks.

Neoadjuvant immune checkpoint blockade in high-risk resectable melanoma

Project description:We conducted a randomized phase II study of neoadjuvant nivolumab versus combined ipilimumab with nivolumab in 23 patients with high-risk resectable melanoma (NCT02519322) and assessed clinical responses and immune correlates. Treatment with combined ipilimumab and nivolumab yielded high response rates (RECIST overall response rate 73%, pathologic complete response rate 45%) but substantial toxicity (73% grade 3 treatment related adverse events), whereas treatment with nivolumab monotherapy yielded modest responses (RECIST overall response rate 25%, pathologic complete response rate 25%) and low toxicity (8% grade 3 treatment related adverse events). Immune correlates of response were identified, demonstrating higher lymphoid infiltrates in responders to both therapies and a more clonal and diverse T cell infiltrate in responders to nivolumab monotherapy. Mutational load was also higher in responders to therapy.
