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.

Project description:We report the RNA sequencing data from the REPEAT study, in which patients with beyond first-line esophagogastric cancer were treated with regorafenib and paclitaxel. For the RNA sequencing, biopsies from metastatic lesions were obtained on baseline (n=21) and fifteen days following treatment initiation (n=13). PURPOSE: Regorafenib monotherapy, a multikinase-inhibitor of angiogenesis, tumor microenvironment, and oncogenesis, showed promising results in gastric cancer. We aimed to assess the tolerability of regorafenib and paclitaxel in advanced esophagogastric cancer (EGC) patients refractory to first-line treatment, and explore potential biomarkers. METHODS: Patients received paclitaxel (80 mg/m2) on days 1, 8, and 15 of a 28-day cycle and regorafenib (80/120/160 mg) on day 1-21 in the dose-escalation cohort, and the maximum-tolerated dose (MTD) in the dose-expansion cohort. Exploratory, overall- (OS) and progression-free survival (PFS) were compared to a propensity-score matched cohort receiving standard second/third line systemic treatment. Paclitaxel pharmacokinetics were assessed using D1 and D15 samples. We performed ELISA measurements of galectin-1, RNA sequencing and shallow whole-genome sequencing of metastatic tumor biopsies for biomarker analyses. RESULTS: In the dose-escalation cohort (n=14), the MTD of regorafenib was 120 mg. Thirty-four patients were enrolled in the dose-expansion cohort. Most common toxicities (all grades; grade ≥3) were fatigue (79%; 4%) and sensory neuropathy (63%; 4%). Best responses achieved were partial response (28%) and stable disease (54%). Median OS and PFS were 7.8 and 4.2 months, respectively (median follow-up 7.8 months). OS (p=0.08) and PFS (p=0.81) were not significantly improved compared to the matched cohort. Paclitaxel concentrations were significantly increased with regorafenib (D15) compared with paclitaxel only (D1; p<0.05); no associations were observed with toxicity or efficacy. An increase in circulating galectin-1 compared to baseline was associated with shorter OS (p<0.01). Enrichment of angiogenesis-related gene expression was observed in short-survivors measured by RNA sequencing. Chromosome 19q13.12-q13.2 amplification was associated with shorter OS (p=0.02) and PFS (p=0.02). CONCLUSION: Treatment with regorafenib and paclitaxel is tolerable and shows promising efficacy in advanced EGC refractory to first-line treatment. Galectin-1 and chromosome 19q13.12-q13.2 amplification could serve as negative predictive biomarkers for treatment response.

Project description:Background: Patients with glioblastoma (GBM) have a dramatically poor prognosis. The recent REGOMA trial suggested an overall survival benefit of regorafenib in recurrent GBM patients. Considering the extreme genetic heterogeneity of GBMs, we aimed to identify molecular biomarkers predictive of differential response to the drug. The study provides evidence that a signature based on the expression of five biomarkers could help identifying a subgroup of GBM patients exhibiting a striking survival advantage when treated with regorafenib. Despite the presented results must be confirmed in larger replication cohorts, the study highlights potential biomarker options to help guiding the clinical decision among regorafenib and other treatments in patients with relapsing GBM. Methods.Total RNA was extracted from tumor samples of patients enrolled in the REGOMA trial. Genome-wide transcriptome and miRNA profiles were associated with patients' Overall Survival (OS) and Progression Free Survival (PFS). Results. At first step, a set of 11 gene transcripts (HIF1A, CTSK, SLC2A1, KLHL12, CDKN1A, CA12, WDR1, CD53, CBR4, NIFK-AS1, RAB30-DT) and 10 miRNAs (miR-93-5p, miR-203a-3p, miR-17-5p, let-7c-3p, miR-101-3p, miR-3607-3p, miR-6516-3p, miR-301a-3p, miR-23b-3p, miR-222-3p) was filtered by comparing survival between regorafenib and lomustine arms. As second step, a minisignature of two gene transcripts (HIF1A, CDKN1A) and three miRNAs (miR-3607-3p, miR-301a-3p, miR-93-5p) identified a subgroup of patients showing prolonged survival after regorafenib administration (median OS range 10.6 - 20.8 months). Conclusions. The study provides evidence that a signature based on the expression of five biomarkers could help identifying a subgroup of GBM patients exhibiting a striking survival advantage when treated with regorafenib. Despite the presented results must be confirmed in larger replication cohorts, the study highlights potential biomarker options to help guiding the clinical decision among regorafenib and other treatments in patients with relapsing GBM.

Project description:Focal adhesion kinase (FAK) is frequently amplified and acts as an immune modulator across cancer types. However, evidence illustrates that targeting FAK is most effective in combination therapy rather than in monotherapy. Here, we demonstrated that the FAK inhibitor, IN10018, and pegylated liposome doxorubicin (PLD) exerted effective antitumor activity preclinically and clinically (clinical trial ID: CTR20200913). The clinical study is a phase Ib trial which includes dose confirmation and expansion sections. The primary endpoint is objective response rate (ORR). Secondary endpoints include disease control rate (DCR), duration of response (DoR), progression-free survival (PFS), overall survival (OS), and safety. As of the data cutoff date (30 November 2022), a total of 61 platinum-resistant ovarian cancer (PROC) patients were enrolled and no IN10018-related grade 4 or 5 adverse effects (AEs) were reported. The ORR was 46.3% (95% confidence interval (CI): 32.6%, 60.4%) and the DCR was 83.3% (95% CI: 70.7%, 92.1%). The median PFS was 7.26 months (95% CI: 5.16 - 8.02 months), and the median duration of response (DoR) was 6.93 months (95% CI: 4.17 - 9.13 months). The primary and secondary endpoints were met. The median OS was not reached, and still maturing. Notably, the regimen exhibited response latency and long-lasting effects in the clinical trial, outcomes frequently observed in immunotherapy. Our preclinical study revealed that the 2-drug combination can maximize the immunogenic cell death (ICD) of cancer cells, boosting the maturation of dendritic cells (DCs) and stimulating CD8 T cells to strengthen the antitumor effects. At present, immune checkpoint blockade (ICB) is widely considered to exert long-term treatment benefits by activating antitumor immunity. However, many cancer patients show poor clinical responses to ICB due in part to the lack of immunogenic niche. Our work confirmed that IN10018 in combination with PLD can prime the tumor microenvironment, supplementing it with sufficient tumor-infiltrating lymphocytes (TILs) to activate antitumor immunity. Correspondingly, animal studies validated that the antitumor effects of ICB can be significantly enhanced by this doublet regimen. The preclinical results warrant further clinical exploration for the triplet regimen with IN10018, PLD, and ICB.

Project description:The DNA methylation signature involved 87 differentially methylated regions (DMR) that distinguished patients’ response to EGFR-TKIs. The methylation level of HOXB9 (cg13643585) which was negatively correlated with gene expression and annotated as function of transcription factor displayed 88% and 92% of sensitivity with respect to objective response rate (ORR, OR=9.25, p=0.0002) and disease control rate (DCR, OR=6.64, p=0.0009), respectively. Importantly, HOXB9 gained methylation in patients with progressive disease (PD) relative to partial response (PR) patients specific to those who harbored EGFR-activating mutations (ORR, OR=8.8, p=0.0045; DCR, OR=6.63, p=0.018).

Project description:Purpose: To determine the 8-week disease control rate (DCR) of sorafenib monotherapy in patients with advanced non-small-cell lung cancer (NSCLC) in the BATTLE trial. Methods: Patients with pre-treated NSCLC, ECOG performance status (PS) 0-2, consented to biopsies to test for biomarker assessment. Sorafenib was given at 400 mg orally twice daily until tumor progression or an unacceptable toxicity. Tumor evaluations were performed at baseline and every 8 weeks. Correlations of outcomes by biomarker groups were analyzed. Results: 105 patients were eligible and 98 patients were evaluable. Median age was 62 (range 34-81) years, 51% of patients were male, 75% were former/current smokers, and 89% had an ECOG PS of 0-1. Median prior chemotherapies for stage IV NSCLC were two. Median follow-up was 9.4 (range: 1.3-32.2) months. Eight-week DCRs by histology were 59.1%, 57.1%, and 55.6% for adenocarcinomas, squamous cell carcinomas and other histologies respectively. Patients with tumors harboring EGFR mutations had significantly lower 8-week DCR compared to patients with wild-type tumors (23.1% vs. 64.2%, P=0.0119), and patients with tumors harboring K-RAS mutations had the highest 8-week DCR (67%). Most commonly reported treatment-related adverse events include hand-foot syndrome (59.6%), fatigue (42.3%), rash (40.4%), diarrhea (38.5%), and weight loss (38.5%). Conclusion: 8-week DCR was better in patients treated with sorafenib who had EGFR wild-type tumors (including those with K-RAS mutations) when compared to those who had EGFR mutations. Additional analyses are warranted to further explore the biology of these tumors and related patient outcomes with sorafenib treatment. ClinicalTrials.gov number, NCT00411671.

Project description:Purpose: To determine the 8-week disease control rate (DCR) of sorafenib monotherapy in patients with advanced non-small-cell lung cancer (NSCLC) in the BATTLE trial. Methods: Patients with pre-treated NSCLC consented to baseline biopsies for pre-specified biomarkers assessment and biomarker discovery. Sorafenib was given at 400 mg orally twice daily until tumor progression or unacceptable toxicity. Outcomes by pre-specified biomarkers were analyzed and a Sorafenib sensitivity signature developed using high-throughput gene expression profiles of NSCLC cell lines and baseline biopsies. Results: 105 patients were eligible and 98 patients were evaluable. Median age was 62 (range 34-81) years, 51% of patients were male, 75% were former/current smokers, and 89% had an ECOG performance status of 0-1. Median prior chemotherapies for stage IV NSCLC were two. Median follow-up was 9.4 (range: 1.3-32.2) months. Overall, 8-week DCR was 58.2%. Patients with EGFR mutations had significantly lower 8-week DCR compared to patients with wild-type tumors (23.1% vs. 64.2%, P=0.0119), and patients with K-RAS mutations had the highest 8-week DCR (67%). Most commonly reported treatment-related adverse events include hand-foot syndrome (59.6%), fatigue (42.3%), rash (40.4%), diarrhea (38.5%), and weight loss (38.5%). Sorafenib sensitivity signature developed in cell lines was associated with an improved outcome. Conclusion: Patients with wild-type EGFR, including those with K-RAS mutation, may benefit from sorafenib as opposed to patients with EGFR mutation. We identify a gene expression signature associated with an improved outcome in patients with wild-type EGFR treated with sorafenib. BATTLE-2 trial is ongoing to validate those results.

Project description:Sitravatinib is an immunomodulatory tyrosine kinase inhibitor that can improve responses when combined with immune checkpoint therapy (ICT). We conducted a phase I trial to determine the optimal dose of triplet therapy with sitravatinib plus nivolumab plus ipilimumab in 22 previously untreated patients with advanced clear cell renal cell carcinoma (ccRCC). The primary endpoint was safety. The addition of even a low sitravatinib dose of 35 mg daily to nivolumab 3 mg/kg and ipilimumab 1 mg/kg resulted in high frequency of immune-related adverse events (irAEs). Subsequent dose reduction of ipilimumab to 0.7 mg/kg in combination with nivolumab 3 mg/kg allowed safe escalation of sitravatinib up to 100 mg daily. Key secondary endpoints were objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). Overall, the triplet combination in the dose-finding setting achieved an ORR of 45.5%, DCR of 86.4%, and a median PFS of 14.5 months with 72.7% of patients alive after a median follow-up of 15.7 months. Single-cell RNA-seq performed in longitudinally collected tumor biopsies from 12 patients treated with the triplet therapy identified a tumor cell-specific epithelial-mesenchymal transition (EMT)-like program associated with treatment resistance and poor outcomes in patients of this trial and in patients of the TCGA ccRCC cohort. Within the tumor microenvironment (TME), the emergence of treatment resistance was characterized by a transition from cytotoxic to exhausted T cell state and enrichment for M2-like myeloid cells. The observed changes in gene expression dynamics and cellular states in tumor cell and TME may help inform future strategies to optimize ICT efficacy.
