e15779 Background: There is paucity of data regarding the best available second-line treatment following progression on gemcitabine-based regimens in metastatic pancreatic ductal adenocarcinoma (PDAC). While a Nanoliposomal formulation of irinotecan (MM398) is considered a standard of care, there is conflicting data relating to the use of oxaliplatin in this setting. We performed a meta-analysis to determine the effectiveness of adding oxaliplatin (OX) or various irinotecan (IRI) formulations to a fluoropyrimidine (FP) as a second-line in PDAC patients. Methods: We searched different databases, including PubMed, Embase and Cochrane, to identify randomized controlled trials comparing FP monotherapy to FP combination therapy that includes either oxaliplatin (FPOX) or various irinotecan formulations (FPIRI) in PDAC patients who progressed after first-line treatment. Secondary analyses were planned to assess the effectiveness of FPOX and FPIRI compared to FP. Outcomes of interest included overall survival (OS) and progression-free survival (PFS). The overall effect was pooled using the DerSimonian and Laird random effects models. Results: Five studies (2 with FPIRI and 3 with FPOX) with 895 patients were identified. Patients randomized to FPIRI/FPOX had a significantly improved PFS (HR = 0.74, CI 0.62 to 0.89) and a trend towards an improved OS compared to FP monotherapy (HR = 0.88, CI 0.65 to 1.19). When comparing FPIRI to FP, there was an improvement in both PFS (HR = 0.64, CI 0.47 to 0.87) and OS (HR = 0.70, CI 0.55 to 0.89) in patients treated with the combination. Conversely, FPOX showed only a modest improvement in PFS (HR = 0.81, CI 0.67, 0.97) with no improvement in OS (HR = 1.03, CI 0.64 to 1.67). Conclusions: Combination chemotherapy with oxaliplatin or various irinotecan formulations seem to improve PFS vs. single agent FP. FPIRI, but not FPOX seem to confer an OS advantage. Oxaliplatin with FP following gemcitabine failure may need further confirmatory studies to establish its role in refractory pancreas cancer.

Background: FOLFIRINOX (fluorouracil, folinic acid, irinotecan plus oxaliplatin) is an effective standard first-line treatment option for advanced pancreatic ductal adenocarcinoma (PDAC). There is no clear consensus on the second-line treatment following progression on FOLFIRINOX. In this multicenter retrospective analysis, we evaluated the efficacy and tolerability of second-line nab-P/Gem (nab-paclitaxel and gemcitabine) after progression on FOLFIRNOX in PDAC. Methods: Patients with unresectable or metastatic PDAC who received nab-P/Gem after progression on FOLFIRINOX between February 2016 and February 2019 were identified from five referral cancer centers in South Korea. Baseline characteristics, treatment history, survival outcomes, and toxicity profile were obtained retrospectively from medical records. Results: A total of 102 patients treated with second-line nab-P/Gem for advanced PDAC after progression on FOLFIRINOX were included. At the time of nab-P/Gem, the median age was 60 years, with males comprising 49.0%, and most (75.5%) had metastatic disease. Patients received a median of three cycles (range 1–12) of nab-P/Gem. The median overall survival (OS) and progression-free survival (PFS) from the start of second-line nab-P/Gem therapy were 9.8 (95% CI, 8.9–10.6) and 4.6 months (3.7–5.5), respectively. A partial response was achieved in 8.5%, and the disease control rate was 73.6%. From the start of first-line FOLFIRIOX, the OS1+2 and PFS1+2 were 20.9 (15.7–26.1) and 13.9 (10.8–17.0) months, respectively, with a 2-year survival rate of 45.1%. There was no treatment-related mortality and grade ⩾3 toxicity was observed in 60.2%. Conclusion: Our results showed that nab-P/Gem was an effective and tolerable second-line treatment option in medically fit patients with advanced PDAC who progressed on first-line FOLFIRNOX.

Doublet Chemotherapy

Purpose Doublet chemotherapy is more effective than single-agent as first-line treatment of advanced non–small-cell lung cancer (NSCLC). As second-line treatment, several randomized trials have been performed comparing single-agent with doublet chemotherapy, but each trial had an insufficient power to detect potentially relevant differences in survival. Methods We performed meta-analysis of individual patient data from randomized trials, both published and unpublished, comparing single-agent with doublet chemotherapy as second-line treatment of advanced NSCLC. Primary end point was overall survival (OS). All statistical analyses were stratified by trial. Results Eight eligible trials were identified. Data of two trials were not available, and data of six trials (847 patients) were collected. Median age was 61 years. Performance status was 0 or 1 in 90%; 80% of patients had received previous platin-based chemotherapy. OS was not significantly different between arms (P = .32). Median OS was 37.3 and 34.7 weeks in the doublet and single-agent arms, respectively. Hazard ratio (HR) was 0.92 (95% CI, 0.79 to 1.08). Response rate was 15.1% with doublet and 7.3% with single-agent (P = .0004). Median progression-free survival was 14 weeks for doublet and 11.7 weeks for single agent (P = .0009; HR, 0.79; 95% CI, 0.68 to 0.91). There was no significant heterogeneity among trials for the three efficacy outcomes. Patients treated with doublet chemotherapy had significantly more grade 3 to 4 hematologic (41% v 25%; P < .0001) and grade 3 to 4 nonhematologic toxicity (28% v 22%; P = .034). Conclusion Doublet chemotherapy as second-line treatment of advanced NSCLC significantly increases response rate and progression-free survival, but is more toxic and does not improve overall survival compared to single-agent.

Pancreatic ductal adenocarcinoma (PDAC) has a bleak prognosis, especially for the majority of patients diagnosed with metastatic disease. The primary option for palliative treatment is chemotherapy, and responses beyond first-line treatment are rare and typically short. Here, we report a case of a 63-year-old woman with PDAC in the head of the pancreas who was initially successfully treated by pancreaticoduodenectomy followed by adjuvant chemotherapy with gemcitabine. However, disease recurrence with liver and para-aortic lymph node metastases was detected only two months after the completion of adjuvant chemotherapy. First-line palliative chemotherapy with gemcitabine-nab/paclitaxel was commenced. The results were discouraging, with disease progression (liver and lung metastases) detected at the first evaluation; the progression-free survival was just two months (64 days). Surprisingly, the response to second-line palliative chemotherapy with 5-fluorouracil-oxaliplatin was excellent; in combination with the ablation of a liver metastasis, this treatment regimen resulted in a complete radiological response and an 11-month treatment-free interval with a sustained good performance status.

e19166 Background: The efficacy of comparing the EGFR-TKI with standard chemotherapy in the second-line treatment of advanced NSCLC with wide-type EGFR were still controversial. To derive a more precise estimation of the two regimens, a meta-analysis was performed. Methods: Medical databases and conference proceedings were searched for randomized controlled trials which compared EGFR-TKI (gefitinib or erlotinib) with standard second-line chemotherapy (docetaxel or pemetrexed) in patients with NSCLC. Endpoints were overall survival, progression-free survival and overall response. Results: Three eligible trials (INTEREST, TITAN and TAILOR) were identified. Lacking for data of overall survival of TAILOR trial, So we only make a preliminary meta-analysis for overall survival. The intention to treatment (ITT) analysis demonstrated that the patients receiving EGFR-TKI had a significantly shorter progression-free survival (PFS) than patients treated with chemotherapy (hazard ratio (HR) = 1.31; 95% confidence intervals (CI) = 1.10-1.56; P = 0.002). The overall survival (OS) and overall response rate (ORR) were coparable between this two groups (HR = 0.96; 95%CI = 0.77-1.19; P = 0.69; relative risk (RR) = 0.37; 95%CI = 0.09-1.54; P = 0.17). Conclusions: Although chemotherapy had a clear superiority in PFS as second-line treatment for patients without EGFR mutations compared with EGFR-TKI, OS and ORR were equal in this two regimens. The toxicity profiles might play an important role in the decision to choose EGFR-TKI or chemotherapy. These findings still need to be verified in larger confirmatory studies in future.

341 Background: Doublet CT demonstrated improved overall response rate (ORR) and progression-free survival (PFS) compared to single agent CT in a MA of patients (pts) receiving II line CT in trials of mUC ( Raggi et al, Ann Oncol 2016). We aimed to update the analyses adding trials of salvage IT. Methods: We searched for arms of phase 2 or 3 studies of salvage single agent anti-programmed cell death-1/Ligand-1 (PD-1/PD-L1) agents pembrolizumab, nivolumab, atezolizumab, durvalumab, avelumab, single agent CT and doublet CT. Random-effects models were used to pool trial level data according to treatment arm, including ORR, median PFS (mPFS), median overall survival (mOS). Univariable (UVA) and multivariable (MVA) analyses were performed, adjusting for ECOG-PS 2 and liver metastases. Results: 7 IT trials were analyzed (n=1,041), 22 arms received single agent CT (n=1,202), and 24 doublet CT (n=708). The pooled ORR was: 21.2% (95%CI: 14.9-29.2) with IT, 14.2% (95%CI: 11.1-17.9) with single agent CT and 31.9% (95%CI: 27.3-36.9) with doublet CT. Pooled mPFS was 1.8, 2.69 and 4.05 months, respectively. Pooled mOS was 8.27, 6.98 and 8.50 months. Pooled median ORR and mOS of IT for PD-L1+ pts were: 30.7% (95%CI: 23.2-39.2) and 11.60 months. Results of UVA and MVA are shown in the table. Only UVA was possible for PD-L1+ pts. Conclusions: Among trials of salvage therapy for mUC, IT was associated with significantly higher ORR and mOS in PD-L1+ pts compared with single agent or doublet CT, while significant differences were not seen in unselected pts. These results are hypothesis-generating and suggest the importance of developing companion predictive biomarkers. [Table: see text]

115 Background: Recent studies have shown efficacy of chemotherapy (CTX) in combination with different biological agents including regorafenib (REG) in second-line treatment of metastatic colorectal cancer (mCRC). As there is no evidence on the relative efficacy and safety of REG as compared to other biological agents in combination with CTX, we evaluated the same in this network meta-analysis (NMA). Methods: Randomized controlled trials (RCTs) comparing efficacy and safety of biological agents + CTX against CTX alone as second-line treatment of mCRC were retrieved from PubMed, EMBASE and Cochrane databases. Progression free survival (PFS) was the primary outcome, while objective response rate (ORR), overall survival (OS) and safety were secondary outcomes. Outcomes were compared by random/mixed-effects NMA using Bayesian (R software, Gemtc package) and frequentist (R software, netmeta package) approaches. Results: Twelve RCTs comparing 9 different treatment regimens with a total of 6805 patients were included for analysis. Hazard ratios (HR)/ odds ratio (OR)/ relative risk (RR) and 95% confidence intervals (CI) for PFS, ORR and grade> 3 adverse events (AE) of selected comparisons from the results of the NMA are shown in table. Conclusions: REG combined with CTX might be a potential alternative to conventional therapeutic options and could be considered as the best option for treating KRAS and BRAF mutated mCRC patients. Future RCTs are needed to confirm our results. [Table: see text]

352 Background: Pancreatic ductal adenocarcinoma still remains a major cause of cancer related deaths in the western world. The current study was conducted to confirm the activity and feasibility of docetaxel/ oxaliplatin combination in second line treatment of advanced pancreatic ductal adenocarcinoma. Methods: Prospective single arm, non-randomized, multi-center, Simon’s two stage phase II trial using docetaxel (75 mg/m2, 60 min, d 1) and oxaliplatin (80 mg/m2, 120 min, d 2) in 21-day cycles. Duration of the trial was scheduled up two 8 cycles. Primary endpoint was tumor response according to RECIST 1.0. Secondary endpoints were progression free survival, overall survival, safety/toxicity, quality of life and clinical benefit. Results: Data represents the intention to treat analysis of 44 patients included between 2008 and 2012. The majority of patients received a gemcitabine based first-line chemotherapy (95.5%). The primary endpoint of tumor response was achieved in 15.9% (7 partial remissions, no complete remission), with a disease control rate of 48% after the first two treatment cycles. Median progression free survival was 7 weeks (CI 6-15.9 weeks) and overall survival 40 weeks (CI 20.4-56.4 weeks). No unexpected adverse events occured. The recorded AEs were mainly hematologic (neutropenia grade 3/4 63.6%, febrile neutropenia 4.6%), gastrointestinal (29.6% grade 3/4 AEs) and infectious (18.2% grade 3/4 AEs). Conclusions: In this single-arm second line trial for the treatment of advanced PDAC, the combination of docetaxel and oxaliplatin shows promising results comparable with other second line protocols such as OFF (oxaliplatin, 5-FU, leucovorin) or liposomal irinotecan (MM-398) plus 5-FU/leucovorin (NAPOLI 1-trial). Some patients seem to benefit particularly as indicated by long periods of treatment in this setting. Even after 8 cycles of treatment with DocOx, partial response was observed in 2 patients and stable disease in another 6 patients corresponding to a disease control rate of 18%. The toxicity profile was quite tolerable and comparable to other second line studies. Clinical trial information: NCT00690300.
