    Abstract: Patients with isolated distal deep vein thrombosis (DVT) have lower rates of adverse outcomes (death, venous thromboembolism [VTE] recurrence or major bleeding) than those with proximal DVT. It is uncertain if such findings are also observed in patients with cancer. METHODS Using data from the international Registro Informatizado de la Enfermedad TromboEmbolica venosa registry, we compared the risks of adverse outcomes at 90 days (adjusted odds ratio [aOR]; 95% CI) and 1 year (adjusted hazard ratio [aHR; 95% CI] ) in 886 patients with cancer-associated distal DVT versus 5,196 patients with cancer-associated proximal DVT and 5,974 patients with non–cancer-associated distal DVT. RESULTS More than 90% of patients in each group were treated with anticoagulants for at least 90 days. At 90 days, the adjusted risks of death, VTE recurrence, or major bleeding were lower in patients with non–cancer-associated distal DVT than in patients with cancer-associated distal DVT (reference): aOR = 0.16 (0.11-0.22), aOR = 0.34 (0.22-0.54), and aOR = 0.47 (0.27-0.80), respectively. The results were similar at 1-year follow-up: aHR = 0.12 (0.09-0.15), aHR = 0.39 (0.28-0.55), and aHR = 0.51 (0.32-0.82), respectively. Risks of death, VTE recurrence, and major bleeding were not statistically different between patients with cancer-associated proximal versus distal DVT, both at 90 days: aOR = 1.11 (0.91-1.36), aOR = 1.10 (0.76-1.62), and aOR = 1.18 (0.76-1.83), respectively, and 1 year: aHR = 1.01 (0.89-1.15), aHR = 1.02 (0.76-1.35), and aHR = 1.10 (0.76-1.61), respectively. However, more patients with cancer-associated proximal DVT, compared with cancer-associated distal DVT, developed fatal pulmonary embolism (PE) during follow-up: The risk difference was 0.40% (95% CI, 0.23 to 0.58). CONCLUSION Cancer-associated distal DVT has serious and relatively comparable outcomes compared with cancer-associated proximal DVT. The lower risk of fatal PE from cancer-associated distal DVT needs further investigation.

    Abstract: 129 Background: Rechallenge therapy with epidermal growth factor receptor (EGFR) inhibitors in chemo-refractory metastatic colorectal cancer (mCRC) is an emerging therapeutic approach. Trifluridine-tipiracil is approved for treatment of chemo-refractory mCRC patients. Methods: Chemo-refractory RAS WT mCRC patients, that had a major response (partial or complete response) to first-line chemotherapy plus an anti-EGFR monoclonal antibody and had an-anti-EGFR drug-free interval during second-line therapy of four or more months were randomized in a phase II trial to assess the addition of the anti-EGFR monoclonal antibody panitumumab to trifluridine-tipiracil as third-line rechallenge therapy. The primary endpoint was progression free survival (PFS). Baseline plasma was analyzed for circulating free tumor (ct) DNA by using Biocartis Idylla platform to detect mutations in KRAS, NRAS, BRAF ( V600E) and EGFRextracellular domain ( S492R). In 24 patients with baseline RAS/BRAF wild type (WT) ctDNA, Foundation One liquid CDx (324 gene profiling) was also performed before treatment and at disease progression. Results: 62 patients were treated with trifluridine-tipiracil (31 patients, arm A) or with trifluridine-tipiracil plus panitumumab (31 patients, arm B). As of September 16, 2022, 1 patient in arm A and 2 patients in arm B were on treatment. The primary endpoint was met. Median PFS (mPFS) was 4 months in arm B versus 2.5 months in arm A [hazard ratio (HR): 0.48; 95% CI 0.28-0.82; P = 0.007]. Baseline plasma RAS/BRAF WT ctDNA was found in 23/31 patients in Arm A and in 26/31 patients in Arm B. In this group, mPFS was 4.5 months in Arm B versus 2.6 months in Arm A (HR: 0.48; 95% CI 0.26-0.89; P = 0.019). Disease control (major responses plus stable disease) was higher for patients in Arm B compared to Arm A (81% versus 48%), whereas disease progression was the best response in 19% versus 52% patients, respectively. PFS rates at 6 and 12 months were 38.5% and 15.4% in arm B versus 13% and 0% in arm A. At disease progression, Foundation One liquid CDx detected several mutations within the EGFR pathway, which could correlate with cancer cell resistance to panitumumab. Conclusions: This is the first prospective randomized trial which evaluated anti-EGFR monoclonal antibody (panitumumab) in addition to standard of care (trifluridine-tipiracil) as third-line rechallenge therapy in chemo-refractory RASWT mCRC patients. Baseline liquid biopsy allows selection of RAS/BRAF WT ctDNA patients who could have a relevant clinical benefit. Clinical trial information: NCT05468892 .

    Abstract: e22008 Background: Nivolumab (nivo) 480 mg (Q4W) flat dose has already been assessed for safety compared to other drug dose regimens in clinical trials [1]. However, few data about melanoma patients treated in real life are available. The aim of our study was to evaluate safety and efficacy in metastatic melanoma pts treated with different schedules of nivo in clinical practice. Methods: We analyzed data from n.124 metastatic melanoma patients who were treated from Jun 2016 to Oct 2019 at NCI of Naples. 83/ 124 (67%) were treated with nivo 480 mg Q4W, and 41/124 (33%) with other schedules (n.26 [63%] with 3 mg/kg, and 15 [37%] with 240 mg Q2W). All patients were stage IV, and n.44/124 (35%) were B-RAF mutated. Nivo was administered as first line in n.95 patients (77%), n. 24 [19%] as second line, and 5 (4%) as third line. Among B-RAF mutated patients, n.23/44 [52%] received a first line with a target-based regimen. According to our previous work [2] we calculated Body Mass Index (BMI). In 93/124 pts the BMI was 〈 25 (75%), while in 31/124 (25%) BMI was ≥ 25. In the table are summarized other clinical characteristics. Hazard Ratios and their 95% confidence intervals (95% CI) were estimated with the Cox model. Association between factors was evaluated with the chi-square test. Results: Our data suggests that nivo 480 mg (Q4W) correlates with a better OS compared with other regimens (HR = 0.48; [95% CI: 0.24-0.96; p = 0.04]). Moreover, better OS trend was also observed in pts with BMI 〉 25 (HR = 0.48; [95% CI: 0.33-1.74]; p = 0.51) and with B-RAF mutation (HR = 0.53; [95% CI: 0.25-1.14); P = 0.10] ). The incidence of any grade toxicities did not differ according the dosage. Conclusions: This retrospective analysis showed a trend of better outcome with nivo 480. This observation warrants further investigation in a larger cohort of pts. [Table: see text]

    Abstract: e22068 Background: Anti-PD-1 agents represent a standard treatment for melanoma patients. However, most patients fail to respond, showing in some cases very rapid disease progression. At moment, there are no effective biomarkers that can predict patient's clinical benefit. The aim of this study is to retrospectively identify gene profiling biomarkers that could help to select melanoma patients who most likely respond to anti-PD-1 therapy. Methods: We defined as fast responder (FR) or fast progressor (FP) patients who got clinical response or clinical progression after two cycles of therapy. We collected data from 44 metastatic melanoma patients (21 FR and 23 FP) treated in first-line with anti-PD1 monotherapy (nivolumab or pembrolizumab) at National Cancer Institute of Naples, Italy. Gene expression profiling analysis was performed using NanoString IO 360 panels on PBMCs collected at baseline from 18 patients (10 FR and 8 FP). Patients with ECOG≥2 were excluded. They were all IV stage (5 M1a, 1 M1b, 12 M1c) of which 15 were B-RAF wild-type (83%) and 3 were B-RAF mutated (17%). Statistical associations between treatment response and gene score variables were estimated by Student’s T tests and correction for multiple comparisons by the Benjamini-Hochberg method. Results: Patterns of gene expression were assessed for correlation to response. We compared PBMCs nanostring analysis between FR and FP patients. We found a higher expression of KRas, CD39, IFI16, IL18, FCGR2A, IL1RN, MAP3K8, TLR5, TLR8, MyD88 and NF-kB in FP patients (all with p-value ≤0.005), most of them related to cell proliferation and immunosuppressive mechanism. Instead we found a higher expression of PRF1, PIK3R1, HLA-DPA1, HLA-DRB1, HLA-DOA, CD45RA, LDHB, KIR3DL2, CD2, CD28, CD7, CD27 in FR patients (all with p-value ≤0.01), most of them related to priming and cytolysis. Conclusions: These preliminary data obtained through gene profiling analysis on baseline PBMCs of melanoma patients suggest that a specific gene signature may discriminate FR or FP patients. Our study provides rationale for further investigating gene profiling signature as a potential association for response to immunotherapy.

    Abstract: 3578 Background: Promising antitumor activity of so called rechallenge treatment with anti-epidermal growth factor receptor (EGFR) drugs in patients with RAS wild type (RAS WT) metastatic colorectal cancer (mCRC) has been recently reported. Beside the absence of resistance mutations at plasma circulating tumor DNA (ctDNA) analysis, no biomarkers of response to anti-EGFR rechallenge strategy have been identified. Methods: We conducted the single arm phase II CAVE mCRC trial to evaluate the combination of cetuximab as rechallenge plus avelumab treatment in 77 RAS WT mCRC patients, with complete (CR) or partial response (PR) to first line chemotherapy plus anti-EGFR drugs, who developed acquired resistance and received a subsequent line of therapy. A post-hoc baseline analysis of circulating tumor DNA (ctDNA) for KRAS, NRAS, BRAF and EGFR-S492R mutations was performed for 67/77 (87%) patients. The correlation of skin toxicity (ST) and other clinical variables with OS, PFS and response rate (RR) was assessed. Results: Cetuximab plus avelumab provided in the intention to treat population (ITT) median overall survival (mOS) of 11.6 months [95% Confidence Interval (CI), 8.4-14.8] and median PFS (mPFS) of 3.6 months (95% CI, 3.2-4.1) with a manageable toxicity profile. Thirty-three (42.9%) patients experienced grade 2-3 ST with mOS of 17.8 months (CI 95% 14.9-20.7), whereas 44 (57.1%) patients with grade 0-1 ST exhibited mOS of 8.2 months (CI 95% 5.6-11), (HR 0.51, CI 95% 0.29-0.89, P = 0.019). mPFS was 4.6 months (CI 95% 3.5-5.8) in patients with grade 2-3 ST, compared to 3.4 months (CI 95% 2.8-4.1) in patients with grade 0-1 ST (HR 0.49, CI 95% 0.3-0.8, P = 0.004). Grade 2-3 ST and baseline RAS/BRAF/EGFR WT ctDNA were the only variables with statistically significant effect on OS both at univariate and multivariate analyses. ST, number of metastatic sites ≤2, surgery of primary tumor and RAS/BRAF/EGFR WT ctDNA were associated with an improvement in PFS only at univariate analysis. In the 33 patients with grade 2-3 ST, 1 (3%) CR, 2 (6.1%) PR and 24 (72.7%) stable disease (SD) were observed, with disease control rate (DCR) of 81.8%. In the 44 patients with grade 0-1 ST 0 CR, 3 (6.8%) PR, 20 (45.5%) SD, with 52.3% DCR were reported. Conclusions: Cetuximab plus avelumab is effective and well tolerated as rechallenge treatment in mCRC. ST is a clinical biomarker for the identification of RAS/BRAF mCRC patients that could benefit from anti-EGFR rechallenge. Clinical trial information: NCT04561336.

    Abstract: e20031 Background: Ipilimumab is the first agent approved for the treatment of advanced melanoma that showed a survival benefit in randomized phase 3 trials. Despite the survival benefit, due to its mechanism of action it is associated with a slow onset and low rate of responses and, in many cases, responses occur after other therapies, like chemotherapy, targeted therapy and radiotherapy. Electrochemotherapy (ECT) has been shown to be effective and well tolerated for local control of metastatic melanoma with superficial lesions. The current challenge is to improve ipilimumab efficacy by combination/sequence with other therapies. We performed a pilot study of combination with ipilimumab and ECT in order to verify the possible increase of response rate. Furthermore, due to the lack of predictive markers, we evaluated the possible predictive role of circulating T-regulatory cells (T-Reg) variations in peripheral blood mononuclear cells (PBMC) of treated patients. Methods: We collected data from 10 patients (pts) with advanced melanoma (6 stage IIIc and 4 stage IV M1c) treated with ipilimumab at 3 mg/kg every 3 weeks for 4 cycles (day 1) and ECT with bleomycine at 15 mg/m2 (day 2) on superficial lesions. Blood draws were collected on day 0, 1 and 2, then on day 15 and 30 from ECT, at each cycle of ipilimumab and at every tumor evaluation (every 12 weeks). PBMC were thawed and labeled with anti-CD4-Pe-Cy-5, CD25-Pe and anti-FoxP3-AlexaFlour488 for T-Reg. Results: 10/10 (100%) pts showed local objective responses (4 CR and 6 PR). 7/10 (70%) pts showed local response (6 PR and 1 CR) after the second ipilimumab dose and 3/10 showed response (3 CR) at week 12. Two pts with PR (28%) out of the group of 7 showed response on distant lesions at week 24 (abscopal effect). All pts are still alive with a median follow up of 11 months (range 6-18). We found in all pts a decrease of T-Reg of 0.10% (range 0.50-2.6%) per cycle and no variation of CD4+ and CD25+ lymphocytes. Conclusions: Our preliminary results show that a combination approach with ipilimumab and ECT may increase responses to ipilimumab. T-Reg decrease in PBMC could be associated with response to treatment. Further studies about this combination are warranted.

    American Society of Clinical Oncology (ASCO) ; 2000

    Abstract: PURPOSE: Sequence-dependent clinical and pharmacokinetic interactions between paclitaxel and doxorubicin have been reported. Some data have shown an influence of paclitaxel on epirubicin metabolism, but no data are available about the effect of diverse sequences of these drugs. We investigated whether reversing the sequence of epirubicin and paclitaxel affects the pattern or degree of toxicity and pharmacokinetics. PATIENTS AND METHODS: Patients receiving epirubicin 90 mg/m 2 by intravenous bolus followed by paclitaxel 175 mg/m 2 over 3-hour infusion or the opposite sequence every 3 weeks for four cycles were eligible. Toxicity was recorded at nadir. Pharmacokinetic data were evaluated at the first and the second cycle and were correlated with toxicity parameters. RESULTS: Thirty-nine consecutive stage II breast cancer patients were treated. Twenty-one patients received epirubicin followed by paclitaxel (ET group), and 18 received the opposite sequence (TE group). No significant difference in nonhematologic toxicity was seen. A lower neutrophil and platelet nadir and a statistically significant slower neutrophil recovery was observed in the TE group. Area under the concentration-time curve (AUC) of epirubicin was higher in the TE group (2,346 ng/mL · h v 1,717 ng/mL · h; P = .002). An inverse linear correlation between epirubicin AUC and neutrophil recovery was also observed (P = .012). No difference was detected in paclitaxel pharmacokinetics. CONCLUSION: Our results support a sequence-dependent effect of paclitaxel over epirubicin pharmacokinetics that is associated with increased myelotoxicity. Because schedule modifications of anthracyclines and paclitaxel can have clinical consequences, the classical way of administration (ie, anthracyclines followed by paclitaxel) should be maintained in clinical practice.
