Adenocarcinoma Of The Pancreas

The combination of nab-paclitaxel and gemcitabine demonstrated greater efficacy than gemcitabine alone but resulted in higher rates of chemotherapy-induced peripheral neuropathy (CINP) in patients with metastatic pancreatic cancer (mPC). We aimed to evaluate the correlation between the development of treatment-related peripheral neuropathy and the efficacy of nab-P/Gem combination in these patients. mPC patients treated with nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2 as a first-line therapy were included. Treatment-related adverse events, mainly peripheral neuropathy, were categorized using the National Cancer Institute Common Toxicity Criteria scale, version 4.02. Efficacy outcomes, including overall survival (OS), progression-free survival (PSF), and disease control rate (DCR), were estimated by the Kaplan–Meier model. A total of 153 patients were analyzed; of these, 47 patients (30.7%) developed grade 1–2 neuropathy. PFS was 7 months (95% CI (6–7 months)) for patients with grade 1–2 neuropathy and 6 months (95% CI (5–6 months)) for patients without peripheral neuropathy (p = 0.42). Median OS was 13 months (95% CI (10–18 months)) and 10 months (95% CI (8–13 months)) in patients with and without peripheral neuropathy, respectively (p = 0.04). DCR was achieved by 83% of patients with grade 1–2 neuropathy and by 58% of patients without neuropathy (p = 0.03). In the multivariate analysis, grade 1–2 neuropathy was independently associated with OS (HR 0.65; 95% CI, 0.45–0.98; p = 0.03). nab-P/Gem represents an optimal first-line treatment for mPC patients. Among possible treatment-related adverse events, peripheral neuropathy is the most frequent, with different grades and incidence. Our study suggests that patients experiencing CINP may have a more favorable outcome, with a higher disease control rate and prolonged median survival compared to those without neuropathy.

BackgroundImmune checkpoint inhibitors (ICI) are first-line therapy for tumors including metastatic renal cell carcinoma (mRCC). Use of ICI is complicated by diverse immune-related adverse events (irAEs), which can add significant morbidity but are also associated with improved efficacy of therapy.1 2 Risk factors for development of irAE are still poorly understood. We hypothesized that patients with mRCC treated with ICI as first-line therapy have higher rates of developing irAE’s than patients previously treated with other therapies.MethodsWe conducted a single-institution, retrospective medical record review of patients with mRCC treated with immune-checkpoint inhibitors from March 2011 through April 15, 2020. We identified therapy duration, and presence, severity, and treatment of adverse events. We defined overall survival as time elapsed from date of diagnosis until death or until completion of study. We classified severity of adverse events according to CTCAE guidelines. Statistical methods included univariate Cox proportional hazards and logistic regression models, and Kaplan-Meier curves were plotted for subgroups.ResultsA total of 64 unique charts were reviewed. 18 patients (28%) of patients were treated with ICI as first-line therapy. 28 patients (44%) experienced immune-related adverse events with a total of 40 irAE’s identified. Most irAE were grade I-II (78%), with 7 (17%) grade III and 1 (2.4%) grade IV irAE’s. Most common sites were skin (29%), thyroid (20%) and gastrointestinal (15%). Patients with irAE had increased survival compared to those who did not have irAE (median survival not reached, vs 139 weeks, p=0.0004) (figure 1). This finding remained after excluding patients who had only experienced dermatologic irAE (median survival not reached in non-derm irAE subgroup, vs 144 weeks for dermatologic or no irAE, p=0.01) (figure 2). Patients treated with ICI as first line therapy had greater rates of developing irAE (72%) than those who had prior therapies (32%) (OR 5.4; p = 0.006). There was no association between histology type and rate of irAE.Abstract 191 Figure 1Kaplan-Meier survival plot of OS between patients with any irAE and those without any irAEAbstract 191 Figure 2Kaplan-Meier survival plot of OS between patients with non-dermatologic irAE and those without any irAE or only dermatologic irAEConclusionsThe development of irAE’s in patients with mRCC treated with ICI is associated with longer survival. This study joins the growing body of evidence showing that presence of irAE’s is associated with increased treatment efficacy. Use of ICI as first-line therapy is associated with higher risk of irAE. Given growing use of ICI as first-line therapy, further study to predict onset and severity of irAE’s is required.AcknowledgementsHong Wang, PhD, for statistical support.Ethics ApprovalThis study was approved by the University of Pittsburgh Institutional Review Board.

Study Results

14502 Background: The oral fluoropyrimidine X (Xeloda®) has improved efficacy, safety and convenience compared with 5-FU/LV in MCRC [Van Cutsem et al. Br J Cancer 2004] and early-stage colon cancer [Twelves et al. NEJM 2005]. A recent study showed that I + X q2w is active and well tolerated [Garcia-Alfonso et al. ESMO 2006]. The humanized monoclonal antibody A (Avastin®) targets VEGF and limits tumor angiogenesis. The addition of A to 5-FU/LV/I (IFL regimen) results in significant improvements in survival among pts with MCRC [Hurwitz et al. NEJM 2004]. Replacing 5-FU/LV with X in this combination is a logical step forward. Here we report data from an open-label phase II trial of XIA in MCRC. Methods: Pts with untreated, histologically confirmed MCRC received I 175 mg/m2 i.v. d1, X 1000 mg/m2 orally bid d2–8, and A 5 mg/m2 d1. Treatment was repeated q2w x12 cycles in the absence of disease progression or unacceptable toxicity. Pts without progressive disease after 12 cycles of XIA continued on the same dose of A + X 1500 mg/m2 bid d2–8, q2w. The primary endpoint was progression-free survival (PFS); secondary endpoints were response rate (RECIST), overall survival (OS), safety, and quality of life. Results: 24 out of a planned total of 32 pts have been enrolled. Baseline characteristics are: M/F 50%/50%; median age 53 years (range 30–70); disease stage at initial diagnosis IIIA/IIIB/IV 29%/21%/50%; no. of metastatic sites 1/>1 50%/50%; most common metastatic site liver; prior adjuvant therapy 33% (Mayo 5-FU/LV). Pts received a median of 12 cycles (range 1–18) of XIA. All 24 pts are evaluable for safety and 22 for efficacy. The overall response rate is 77% (4 CR, 13 PR); 2 pts (9%) have stable disease and 3 have progressed. One pt has died. Median PFS and median OS have not yet been reached. The only grade 3 adverse events are diarrhea (13%), fatigue (4%), mucositis (4%), enteritis (4%), ileus (4%); there is one report of grade 4 leucopenia. All other adverse events are mild-to-moderate. Conclusions: The XIA combination appears to be highly active and well tolerated as first-line treatment for MCRC, providing support for further evaluation of this combination. No significant financial relationships to disclose.

The Cost

216 Background: Despite a large number of randomized trials, there is no consensus as to the best regimen for advanced gastroesophageal cancer. Combination therapy with docetaxel, cisplatin, and 5-FU has shown increased response rates, progression-free survival (PFS) and overall survival (OS), but at the cost of significant toxicity. Based on a small phase II study, FLOT has been adopted by some groups given its better toxicity profile. We aim at reporting our experience with this regimen Methods: Patients with unresectable advanced gastroesophageal adenocarcinoma who received FLOT (oxaliplatin 85 mg/m2, leucovorin 200 mg/m2, and fluorouracil 2600 mg/m2 as a 24h infusion in combination with docetaxel 50 mg/m2 on day 1 every 2 weeks) as first-line therapy at our institution were retrospectively evaluated. PFS and OS were estimated by the Kaplan-Meier method. Results: A total of 23 patients were reviewed, most of them with metastatic disease (60%). Median age was 56 years (range 26–76) and 74% were male. Median PFS and OS were 5,2 (95% CI 4,0-6,3) and 8,5 months (95% CI 4,4-12,6), respectively. Only 13%of the patients experienced prolonged PFS (>12 months). There were no deaths due to the treatment. Conclusions: Before FLOT could be adopted as a first-line regimen for metastatic gastroesophageal cancer, phase III trials are urgently needed comparing FLOT with more traditional regimens.

The IFCT-0504 phase II trial evaluated the efficacy of erlotinibversuscarboplatin–paclitaxel (CP) as first-line treatment in 130 cases of advanced lepidic-predominant adenocarcinoma (ADC).The primary objective of the study was treatment efficacy, evaluated based on an end-point of disease control at 16 weeks.The primary objective was met, with a disease control in 35 (53%) out of 66 patients treated with CP and in 25 (39.1%) out of 64 patients treated with erlotinib. Median progression-free survival (PFS) for the total population was 3.6 months. The disease control rate did not differ between either the therapeutic arms or pathological subtypes, whereas there was a strong interaction between treatment arms and tumour pathological subtypes for PFS (p=0.009). Mucinous tumour patients treated with erlotinib exhibited an increased progression risk (hazard ratio 3.4, 95% CI 1.7–6.5; p≤0.001). The PFS for nonmucinous tumour patients was similar in both arms. Median overall survival was 20.1 months and did not differ between therapeutic arms. These findings were not further elucidated by molecular analyses and the toxicity profiles were as expected.Our study demonstrated the dominant role of CP alongside erlotinib in the management of advanced lepidic ADC. Based on these findings, erlotinib should not be administered in first-line therapy to patients with lepidic ADC in the absence of an epidermal growth factor receptor mutation.

Abstract Background Malignancies are molecularly complex and become more resistant with each line of therapy. We hypothesized that offering matched, individualized combination therapies to patients with treatment-naïve, advanced cancers would be feasible and efficacious. Patients with newly diagnosed unresectable/metastatic, poor-prognosis cancers were enrolled in a cross-institutional prospective study. Methods A total of 145 patients were included in the study. Genomic profiling (tissue and/or circulating tumor DNA) was performed in all patients, and PD-L1 immunohistochemistry, tumor mutational burden, and microsatellite status assessment were performed in a subset of patients. We evaluated safety and outcomes: disease-control rate (stable disease for ≥ 6 months or partial or complete response), progression-free survival (PFS), and overall survival (OS). Results Seventy-six of 145 patients (52%) were treated, most commonly for non-colorectal gastrointestinal cancers, carcinomas of unknown primary, and hepatobiliary malignancies (53% women; median age, 63 years). The median number of deleterious genomic alterations per patient was 5 (range, 0–15). Fifty-four treated patients (71%) received ≥ 1 molecularly matched therapy, demonstrating the feasibility of administering molecularly matched therapy. The Matching Score, which reflects the percentage of targeted alterations, correlated linearly with progression-free survival (R2 = 0.92; P = 0.01), and high (≥ 60%) Matching Score was an independent predictor of improved disease control rate [OR 3.31 (95% CI 1.01–10.83), P = 0.048], PFS [HR 0.55 (0.28–1.07), P = 0.08], and OS [HR 0.42 (0.21–0.85), P = 0.02]. Serious adverse event rates were similar in the unmatched and matched groups. Conclusions Personalized combination therapies targeting a majority of a patient’s molecular alterations have antitumor activity as first-line treatment. These findings underscore the feasibility and importance of using tailored N-of-1 combination therapies early in the course of lethal malignancies. Trial registration I-PREDICT (NCT02534675) was registered on August 25, 2015.

The Impact

633 Background: The synthetic DNA-based immunomodulator MGN1703 acts as an agonist of toll-like receptor 9. Based on promising data from a phase I study in patients with metastatic solid tumors including those with CRC, a phase II-III study was initiated in patients with advanced CRC having disease control after first-line therapy. The objective of the study is to assess efficacy and safety of the MGN1703 treatment in comparison to placebo. Methods: The IMPACT study is designed as a randomized double-blind placebo-controlled phase II-III study, which is conducted in patients with advanced CRC showing disease control after first-line therapy with standard chemotherapy regimen. The treatment is administered subcutaneously twice weekly in a ratio 2:1 (60 mg MGN1703 or placebo). The study is conducted in Germany, Austria, France, UK, Czech Republic and Russia, and 129 patients will be recruited into the study. The efficacy and safety of the study treatment will be evaluated based on extensive immunological tests, radiological assessment, safety laboratory results and assessments of the quality of life. The study treatment will be continued until tumor progression, intolerable toxicity, exclusion criteria or withdrawal of consent. Results: The majority of adverse events were assessed as not drug-related by the investigator. The remaining AEs include mild night sweat (not assessable), mild fever (at three occasions, possible related), and mild arthralgia (certain related) in one patient each. Three SAE have been reported so far of which one was assessed as probably drug-related – atypical pneumonia. Only in single patients local reactions such as mild redness and swelling at injection site were reported. No laboratory or clinical signs of autoimmunity or dose-limiting toxicities were reported, so far. Conclusions: With these preliminary safety results of the ongoing clinical study in patients with advanced CRC it could be shown that ttreatment with MGN1703 at the dosage of 60 mg is well tolerated and safe. Reported adverse events assessed as possibly drug-related belong to expected study drug reactions known for immune modulating drugs. These events were not accompanied by any signs of autoimmunity.

363 Background: Emerging literature has suggested the benefit of capecitabine/temozolomide (C/T) therapy in metastatic pancreatic NETs (pNETs) as first line therapy. We conducted a retrospective analysis of the efficacy of (C/T) therapy in all patients with metastatic NETs treated at MSKCC. Methods: Using the electronic pharmacy database, we included all patients’ ≥ 18 years of age who received C/T combination therapy for pNETs between 1/2003-10/2010. Primary endpoint was the overall response rate (ORR). Secondary endpoints included progression-free survival (PFS) and overall survival (OS). Response rates were evaluated by a radiologist using CT scans and per RECIST 1.1. MGMT tumor expression was conducted to correlate with response. Results: Twenty patients (mean age 64, 35% female) were identified. There were 16 (80%) pNETs (1 functional, 15 nonfunctional), 2 (10%) carcinoid, 1 high grade biliary (5%) and 1 (5%) gastric neuroendocrine carcinoma. Eight tumors were low grade (1 carcinoid, 7 pNET), 8 intermediate grade (7 pNET, 1 carcinoid), and 4 high grade (2 pNET, 1 stomach, 1 biliary). Twelve (60%) received C/T in the first-line setting and 8 in the relapsed setting. Six (30%) had a partial response and 7 (35%) had stable disease. There were no complete responses ( Table 1 ). With a median follow-up of approximately 3 years, the PFS was 16.4 months. Four pNET patients had unresectable disease at presentation and 2/4 were resected and rendered free of disease after C/T therapy. There were no high grade responders. Liver tumor burden (0%, <10%, 10-50%, >50%), number of prior treatments, and tumor grade did not predict response. Grade 3-4 events potentially related to C/T included neutropenia (1/20, 5%), nausea (3/20 15%), diarrhea (1/20, 5%), and fatigue (3/20, 15%). Conclusions: Combination C/T for the treatment of pNETs is an effective regimen for well differentiated NETs irrespective of tumor burden and prior treatment. No responses were seen in our carcinoid patients. MGMT expression will be presented at the meeting. [Table: see text]

11051 Background: Uterine sarcomas are associated with poor prognosis snce the complete remission is extreme rare. Therefore, treatment with chemotherapy including eribulin or trabectedin, hormone therapy or molecular-targeted therapy including pazopanib or olaratumab was expectd, but the effect is not satisfactory. Thus, we evaluated the effects of temozoromide (T), derivateives of dacarbazine, and bevacizumab (B) (TB) containing or not cabozantinib (C), a multikinase inhibitor of MET, AXL, RET and VEGFR2 (TBC) in heavily pretreated cases of uterine sarcomas. Methods: From 2009 to 2018, 29 patients (pts) with heavily pretreated uterine sarcomas were enrolled. Fifteen of 29 patients were treated with T (80mg/body/day) and B (2mg/kg; days1, 8 and 15, q 4 weeks) (TB). Since 2013, C (140mg/body/week) was added to TB (TBC, n = 14). Treatment was continued until disease progression and/or unmanageable toxicities. Response was evaluated with the response evaluation criteria in solid tumors (RECIST) v1.1, and adverse events were assessed by common terminology criteria for adverse events (CTCAE) v4.0. Results: Seven pts (24 %) had carcinosarcoma, fifteen (52 %) had leiomyosarcoma, five (17 %) had undifferentiated uterine sarcoma, one (3 %) had adenosarcoma, and one (3 %) had uterine sarcoma-not other specified. Twenty-three of 29 pts were subjected to response evaluation. Five pts (22 %) had complete response (CR), three (13 %) had partial response, six (26 %) had stable disease (SD). The response rate (RR: CR+PR) and disease-control rate (DCR: CR+PR+SD) were 35 % and 70 %, respectively. The median progression-free survival was 6.5 (2-89) months. When adding C to T and B, DCR was improved from 64 % (TB) to 75% (TBC). Median administration of cycles is 7 (TB) and 5 (TBC). There were 2 dead cases from perforation, but toxicity was almost mild and manageable. Conclusions: We have experienced 5 cases of CR by TB or TBC. Moreover, addition of C to T and B resulted in better disease-control rate. Compared to other reported treatment, TB combined with C could be substantially effective in cases with heavily pretreated uterine sarcomas. These results warrant further prospective and randomized studies.

e15533 Background: Thalidomide (T) is an anti-angiogenic agent with modest activity in advanced/metastatic HCC. Tegafur/uracil (UFT) is an oral prodrug of 5-fluorouracil with activity against various gastrointestinal cancers. Metronomic chemotherapy has been shown to have anti-angiogenic and anti-cancer effect in preclinical and clinical models. This study evaluated the efficacy and safety of the combination of T and metronomic UFT as first-line therapy for advanced HCC. Methods: Patients (Pts) with advanced HCC not treatable by surgery or other loco-regional therapies received T 100mg bid and UFT 125mg/m2 (based on tegafur) bid continuously. Treatment was continued in the absence of disease progression or unacceptable toxicity. Primary endpoint was response rate (RR) by RECIST; secondary endpoints were disease control rate (CR+PR+SD), progression-free survival (PFS), overall survival (OS), and safety. Results: Between Jul 2006 and Jul 2008, 43 intent-to-treat pts (M/F 41/2, median age 55) were enrolled. Baseline characteristics were HBsAg(+)/anti-HCV(+)/both(+) /both(-) 31/6/1/7; AJCC stage II/III/IV 2/18/23; BCLC stage B/C 1/42; CLIP score ≤3/4 27/16; portal vein thrombosis 65%; extrahepatic metastasis 58%; prior local treatment 72%. There were 4 PR (9.3%) and 10 SD (23.3%), with a disease control rate of 32.6%. Median OS was 4.6 (95% CI, 3.5–7.3) months and median PFS was 1.9 (95% CI, 1.8–2.6) months. The OS and PFS for pts with CLIP score ≤3 were 7.6 and 2.6 months, respectively. Grade 3 leucopenia developed in 1 (2.3%) pt. The most common treatment-related grade 3 non-hematologic toxicities were somnolence (n=4, 9.3%), GI bleeding (n=3, 7.0%), and elevated transaminase (n=2, 4.7%). No grade 4 toxicities occurred. Conclusions: The combination of T with metronomic UFT is a well-tolerated regimen with moderate activity for advanced HCC, and worth further exploration in pts with CLIP score ≤3. [Table: see text]

93 Background: Since PPS may influence overall survival (OS), studying PPS may help in understanding why gains in PFS do not always translate into gains in OS. Methods: We searched PubMed for RCTs on first-line therapy for AGC published between 01/82 and 01/12. We estimated mean PFS and OS (in months) using the area under the published Kaplan-Meier curves, computing mean PPS as mean OS minus mean PFS for each trial arm. We compared PPS between trial arms grouped according to PFS duration (longer versus shorter PFS, regardless of statistical significance) and world region (using t tests). Results: We retrieved 53 trials (25 were phase III, 24 were randomized phase II, and 4 had no explicit phase) enrolling 12,050 patients in 121 arms. We could estimate mean endpoints for 33 trials (26/6/1 with 2/3/4 arms), which were more likely to be phase III than the 20 trials with no Kaplan-Meier curves for both endpoints. The average mean PPS was almost identical between trial arms with longer or shorter PFS. Use of PPS assessed as median OS minus median PFS yielded qualitatively similar results. Conclusions: Treatments that improve PFS do not seem to influence PPS. Asian trials appear to have longer OS due to longer PPS, not PFS. Work with individual patient data collected worldwide by the GASTRIC group is under way to confirm our findings. [Table: see text]
