Project description:While patients with microsatellite instable, metastatic colorectal cancer (CRC) benefit from immune checkpoint blockade, chemotherapy with targeted therapies remains the only therapeutic option for microsatellite stable (MSS) tumors. The single arm, phase IB/II MEDITREME trial evaluates safety and efficacy of durvalumab plus tremelimumab in combination with mFOLFOX6 chemotherapy in first line, in 57 patients with RAS-mutant unresectable mCRC. Safety was primary objective of phase IB and no safety issue was observed. The primary objective of phase II was efficacy in terms of 3-month PFS in MSS patients, which was met with a 3 month PFS of 90.7% [95% CI: 79.2-96%]. For secondary objective, response rate was 64.5%, median PFS was 8.2 months [95% CI: 5.9–8.6] and overall survival was not reached in MSS patients. Higher tumor mutational burden and a lower degree of genomic instability in responder patients. Integrated transcriptomic analysis underlined that high immune signature, and low epithelio-mesenchymal transition were associated with better outcome. Immunomonitoring showed induction of neoantigen and NY-ESO1 and TERT blood tumor specific T cell response associated with better PFS. The combination of durvalumab-tremelimumab with mFOLFOX6 was tolerable with promising clinical activity in MSS mCRC.

Project description:Importance: Autophagy has been identified as a resistance mechanism to BRAF and MEK inhibition in BRAF mutant melanoma. In the BAMM trial, hydroxychloroquine (HCQ) was used to inhibit autophagy in combination with dabrafenib and trametenib in BRAF mutant melanoma patients. Objective: To a) determine safety and maximal tolerated dose (MTD) of hydroxychloroquine when combined with dabrafenib and trametinib and b) determine antitumor activity of the combination. Design: Open label non-randomized phase I/II clinical trial Setting: Prospective therapeutic clinical trial conducted in 4 centers Participants: Unresectable Stage III or Stage IV BRAF mutant melanoma patients Intrevention: HCQ twice daily, dabrafenib 150 mg twice daily and trametinib 2 mg daily (D+T) Main Outcome: Primary outcomes were safety and 1-year progression-free survival (PFS) rate Results: Between December 2014 and January 2020, 50 patients were screened, 38 patients were enrolled and evaluable for toxicity and 34 patients were evaluable for 1-year PFS rate. Patient demographics were: 29% were ECOG PS 1, 47% had elevated LDH, 52% were Stage IV M1c or M1d and 53% had previously received therapy for advanced melanoma. In the phase I trial there was no dose limiting toxicity of HCQ at either 400 (n=3) or 600 (MTD) mg po bid combined with D+T. For the entire study population, the 1-year PFS rate was 41% (95% CI = ), median PFS was 11.9 months (95% CI = ), overall response rate (ORR) was 85% (95% exact CI=64-95%)and complete response rate of 41% (95% exact CI=25-59%). In a prespecificed subgroup analysis in 18 patients with elevated LDH, the ORR was 88% and median PFS was 8 months Conlusion and Relevance: The combination of HCQ, dabrafenib and trametinib was well tolerated and produced a high response rate but did not meet the prespecified criteria for success with respect to the 1-year PFS rate. In patients with elevated LDH , the response rate and PFS were encouraging. A randomized placebo controlled trial of dabrafenib and trametinib with/without HCQ in advanced BRAF mutant melanoma patients with elevated LDH and previously treated with immunotherapy is being conducted through the National Clinical Trial Network.

Project description:Inhibition of the B-cell receptor pathway, and specifically of Bruton tyrosine kinase (BTK), is a leading therapeutic strategy in chronic lymphocytic leukemia (CLL). Target occupancy has been measured as a pharmacodynamic parameter in clinical studies of covalent BTK inhibitors. However, the kinetics of BTK turnover, which determines occupancy, and the relationship between occupancy, pathway inhibition and clinical outcomes remains undefined. This randomized phase 2 study investigated the safety, efficacy, and pharmacodynamics of a selective BTK inhibitor acalabrutinib at 100 mg twice daily or 200 mg once daily in 48 patients with relapsed/refractory or high-risk treatment naïve CLL. Acalabrutinib was well tolerated and yielded an overall response rate (ORR) of partial response or better of 95.8% (95% CI 78.9%, 99.9%) and an estimated progression-free survival (PFS) rate at 24 months of 91.5% (95% CI 70.0%, 97.8%) with twice daily dosing and an ORR of 79.2% (95% CI 57.9%, 92.9%) and an estimated PFS rate at 24 months of 87.2% (95% CI 57.2%, 96.7%) with once daily dosing. BTK resynthesis was faster in CLL than in healthy volunteers. Twice daily dosing maintained higher BTK occupancy and achieved more potent pathway inhibition compared to once daily dosing. Additional follow-up is required to address the impact of dosing schedule and BTK occupancy on long-term clinical outcomes.

Project description:CAMILLA is a basket trial (NCT03539822) evaluating cabozantinib plus the ICI durvalumab in chemorefractory gastrointestinal cancer. Herein, are the phase II colorectal cohort results. 29 patients were evaluable. 100% had confirmed pMMR/MSS tumors. Primary endpoint was met with ORR of 27.6% (95% CI 12.7-47.2%). Secondary endpoints of 4-month PFS rate was 44.83% (95% CI 26.5-64.3%); and median OS was 9.1 months (95% CI 5.8-20.2). Grade≥3 TRAE occurred in 39%. In post-hoc analysis of patients with RAS wild type tumors, ORR was 50% and median PFS and OS were 6.3 and 21.5 months respectively. Exploratory spatial transcriptomic profiling of pretreatment tumors showed upregulation of VEGF and MET signaling, increased extracellular matrix activity and pre-existing anti-tumor immune responses coexisting with immune suppressive features like T cell migration barriers in responders versus non-responders. Cabozantinib plus durvalumab demonstrated anti-tumor activity, manageable toxicity, and have led to the activation of the phase III STELLAR-303 trial.

Project description:There are many treatment options available for men with metastatic castration-resistant prostate cancer (mCRPC). Yet, biomarkers predictive of differential response to treatment are currently available. A recent translational study suggested that SLCO2B1 genotype could predict response to abiraterone acetate (AA) for men with advanced prostate cancer. Here, we investigate whether germline variants in SLCO2B1 are predictive of response to first-line AA in men with new mCRPC. Clinical data and samples were analyzed from a prospective prostate cancer registry at the University of Utah. Genotyping was performed using the Illumina OmniExpress genotyping platform. Primary endpoint was progression-free survival (PFS) on first-line AA in men with mCRPC. We performed a pre-specified multivariate Cox regression analysis to assess the independent predictive value of rs12422149 and rs1789693 on PFS on AA. Of 401 men with advanced prostate cancer genotyped, 323 were homozygous wild type for rs12422149 (80.5%), 74 were heterozygous (18.5%), and 4 were homozygous variant (1.0%). In a multivariate analysis of 79 men treated with first-line AA for mCRPC, men heterozygous for rs12422149 had significantly improved median PFS compared to the homozygous wild-type group (8.9 months vs. 6.3 months, HR 0.46, 95% CI 0.23-0.94, p=0.03). No significant difference in median PFS was seen by rs1789693 genotype. In this first clinical validation of translational data reported by Mostaghel and colleagues, germline variant alleles in rs12422149 of SLCO2B1 are common and predict improved response to first-line AA In men with mCRPC.

Project description:Nowadays, risk stratification for oropharyngeal squamous cell carcinoma (OPSCC) is based on HPV status, tobacco smoking, and tumor stage. Although HPV positivity represents a strong prognostic factor for both reduced risk of relapse, and improved survival, there is a subset of HPV-positive OPSCC patients who still experience poor outcomes. Furthermore, HPV-negative OPSCC patients, who have an even higher risk of relapse within two years from the end of the treatment, are still lacking suitable prognostic biomarkers for clinical outcome. In this scenario, inclusion of new biomarkers that differentiate OPSCC patients with a diverse prognosis is urgently needed. Since genes encoding for epigenetic regulators have been frequently found mutated in several tumors, including OPSCC, it is expected that epigenetic changes may play a major role in OPSCC pathogenesis and response to therapy. Consistently, HPV oncoproteins have been also demonstrated to impact on epigenetic pattern by interacting with different epigenetic regulators, thus affecting the chromatin landscape of OPSCC HPV-positive cells. Along this line, we have recently demonstrated the methylation levels of the “Long interspersed nucleotide element-1” (LINE-1) repetitive elements, a widely accepted surrogate of overall genomic DNA methylation content, was different between HPV16-positive and -negative OPSCC patients. In particular, the lowest level of LINE-1 element methylation was observed in HPV16-negative OPSCC patients who relapsed within 24 months, thus indicating the overall level of genomic DNA methylation may have an impact on early OPSCC relapse risk. Despite these promising initial data, the influence of LINE1 methylation levels on OPSCC survival is not yet well defined. We retrospectively reviewed a cohort of 156 patients with stage III–IVB (AJCC TNM 7th Ed.) OPSCC. Forty patients were diagnosed and treated at Treviso Regional Hospital, and 116 at National Cancer Institute of Aviano and/or Pordenone Hospital. All patients were managed with curative intent with elective radiotherapy ± chemotherapy or surgery ± adjuvant (chemo)radiotherapy, in accordance with current clinical practice. Genomic DNA was extracted from OPSCC formalin-fixed paraffin-embedded tissues. The quantification of HPV16 DNA was performed by real-time quantitative PCR by using specific primers for the amplification of a region spanning the E6 genes of the HPV16 genome, whereas the methylation status of LINE1 repetitive sequences was evaluated by real-time quantitative Methylation-Specific PCR. The impact of genome-wide methylation patterns on progression-free survival (PFS) and overall survival (OS) was assessed using Kaplan-Meier analyses. Optimal cut-points for LINE-1 were search through a recursive algorithm which estimates the predictive value for PFS (Harrell's c-index) for each possible couple of LINE-1 values; optimal cut-points were defined as those which maximized Harrell's c-index. Multivariate hazard risk (HR) and corresponding confidence intervals (CI) were calculated according to Cox proportional hazard model adjusting for gender, age, TNM stage, and HPV status.The median follow up was 30 months (interquartile range: 17-72 months) Considering all cases, PFS and OS were respectively 64.6% and 71.8% at 2 years, and 49.5% and 53.7% at 5 years. HPV DNA prevalence was 28.8% (45/156). Compared to HPV-negative patients, HPV-positive ones had a better outcome in terms of PFS at 2 (81.0% vs. 58.2%) and 5 years (70.9% vs 41.6%; p=0.003), as well as in terms of OS (5-year OS: 74.1 vs. 45.9%, respectively; p=0.003). LINE-1 methylation level was significantly higher in HPV-positive OPSCC patients than in HPV-negative ones (median, 66.9% and 48.7% respectively; p<0.001). Three patterns of LINE-1 methylation status were indentified according to PFS: high ≥55%, medium 35-54%, low <35%. The same cut-points were identified from the analysis on OS. Analyzing all patients, PFS at 2 years was 75.9% in the high methylation group, 62.0% in the intermediate group, and 41.6% in the low methylation group (p≤0.001). Compared to LINE-1≥55%, multivariate HR were 1.66 (95% CI: 0.92-2.99) for LINE-1 35-54% and 2.84 (95% CI: 1.51-5.37) for LINE-1<35%. Moreover, OS at 2 and 5 years was significantly better in the high methylation group (p<0.001), with HRs of death similar to those for PFS. It is worth noting that the level of LINE-1 remained a prognostic factor for both PFS (p= 0.004) and of OS (p=0.011) when we restricted the analysis to HPV-negative patients. Among these patients, the multivariate HRs for LINE-1<35% were 2.87 (95% CI: 1.49-5.52) for PFS and 2.86 (1.43-5.74) for OS. In HPV-positive group, respect to patients with LINE-1 <55%, cases with a LINE-1≥55% have had better trend in terms of PFS and OS, but this difference was not statistically significant (p=0.112; p= 0.113), mainly due to small sample size. Between HPV-positive patients, only one had a methylation of LINE-1 < 35%. LINE-1 methylation has been identified as a molecular marker of prognosis for stage III-IV OPSCC patients, becoming a promising biomarker to be integrated in current prognostic factors (e.g., stage, HPV status, tobacco smoking) to refine the comprehensive clinical management of OPSCC. This is of particular clinical relevance for HPV-positive OPSCC patients, since this marker may help in indentify the subset of these patients with bad prognosis. However, further validation in a prospective study is needed for its application in daily clinical practice.

Project description:Immune checkpoint inhibitors (ICIs) targeting PD-1/L1 have modest efficacy in hepatocellular carcinoma (HCC) as single agents, but combination regimens have demonstrated increased clinical benefit at the expense of treatment toxicities. Exposed phosphatidylserine suppresses the innate immune response in the tumor microenvironment (TME). Targeting phosphatidylserine does not induce tumor responses in the clinical setting when used as monotherapy or in combination with cytotoxic and targeted therapies, but may induce pro-inflammatory and –immune stimulating effects that enhance ICI activity. This hypothesis was tested in a single-arm phase 2 trial evaluating bavituximab, a phosphatidylserine targeting antibody, plus pembrolizumab in patients with unresectable HCC who had not received prior systemic treatments (ClinicalTrials.gov ID: NCT03519997). The primary end point was investigator-assessed objective response rate (ORR) among evaluable patients, and secondary end points included progression-free survival (PFS) and the incidence of adverse events. Among 28 evaluable patients, the ORR was 32.1%, including 2 complete responses, and a disease control rate of 64.3%. Median PFS was 6.3 months (95% CI, 1.3-11.3 months). Treatment related adverse events of any grade occurred in 45.7% of patients with grade 3 or 4 adverse events occurring in 14.3% of patients. Exploratory analyses of baseline tumor specimens showed that a depletion of B cells, and the expression of smooth muscle actin and immune checkpoints in stroma was associated with tumor response. An RNA-based TME assay which distinguishes immune-rich of inflammatory tumors was also shown to be predictive of ORR. These results suggest that targeting phosphatidylserine may lead to synergistic effects with ICIs without increasing toxicity rates, and future studies on this therapeutic strategy may be guided by biomarkers characterizing the TME.

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.
