685 Background: The FIRE3 study reported that cetuximab added to first line combination chemotherapy versus the addition of bevacizumab to the same chemotherapy backbone, with a planned switch to the alternative biologic in second line therapy, resulted in improved overall survival. One possible explanation is that the sequence of biologic administration in mCRC impacts on treatment benefit. Examination of the efficacy of anti-EGFR therapy in cohorts where patients have and have not received prior bevacizumab will inform this. Methods: We interrogated our prospective database (ACCORD), which records comprehensive detail on demographics, treatments received and patient outcomes for consecutive mCRC patients in real world practice across multiple institutions in Australia. We included patients receiving 2nd and subsequent line anti-EGFR monotherapy. Disease control rate (DCR) (partial response plus stable disease), progression free survival (PFS) and overall survival (OS) from the start of anti-EGFR were determined as a function of prior bevacizumab use. Results: From a total of 1511 patients treated between 01/10/2002 and 31/12/2014,129 patients treated with single agent anti- EGFR were identified, 75 had received prior bevacizumab. Demographics, performance status and tumour characteristics were similar between the 2 groups. 84% were confirmed KRAS exon 2 wild type. Prior treatment with bevacizumab did not impact DCR (35% vs 40%, p = 0.5065), median PFS (3.0 vs 3.0 months, p = 0.9460) or OS (8.6 vs 8.4 months, HR 0.95, p = 0.8073). Similarly, for bevacizumab treated patients, the time since last dose of bevacizumab to start of anti-EGFR ( < 3 months (n = 26) vs 3-6 months (n = 17) vs > 6 months (n = 32)) did not impact PFS (2.3 vs 3.6 vs 3 months) or OS (8.9 vs 10.1 vs 7.1 months, HR: 0.88, p = 0.82). Conclusions: There was no evident impact of previous bevacizumab treatment, or time from previous bevacizumab treatment, on the efficacy of single agent anti-EGFR therapy in a routine clinical practice cohort. Our data do not support the notion that prior bevacizumab renders tumors more or less sensitive to subsequent anti EGFR therapy.

356 Background: A randomized phase II trial evaluating So plus IL-2 versus So alone as first-line treatment of mRCC, did not show any difference in progression-free survival (PFS) (primary endpoint) between the two groups. The final overall survival analysis is here reported. Methods: In this open-label phase II study, 128 patients with mRCC were randomized to receive either oral So 400 mg bid continuous dosing plus IL-2 4.5 MIU subcutaneously administered 5 times weekly for 6 weeks every 8 weeks (Arm A), or So alone (Arm B). At relapse, most patients of the two arms underwent treatment with other targeted therapies (TTs) including sunitinib, everolimus, and axitinib. Overall survival was estimated by Kaplan-Meier method and compared by two-sided log-rank test. Results: According to Motzer criteria 55 % of the patients were low risk in both arms, and 41% and 39% were intermediate risk in Arm A and B respectively. After a median follow-up time of 58 months (interquartile range: 28-63 months), the median OS was 38 and 33 months in Arm A and B, respectively (p = 0.667). Five-year OS was 26.3% (95% CI: 15.9-43.5) for the combination arm and 23.1% (95% CI: 13.2-40.5) for single agent arm. The overall number of death was 85, 42 of whom in the So monotherapy group. Median PFS survival was 7.3 and 6.9 months for Arm A and B, respectively (p = 0.109). Overall, 49 (77%) and 48 (75%) patients in Arm A and B, respectively, received at least one subsequent targeted therapy (TTs). The most common adverse events (AEs) in both arms were asthenia, hand-foot syndrome, hypertension and diarrhoea. Grade 3-4 AEs were documented in 38% of patients treated with the combination regimen and in 25% of those undergoing single agent treatment. Conclusions: The OS results suggest an improved outcome in patients with mRCC treated with TTs which appears independent of the treatment initially administered. This prospective study, regarding use of sorafenib in first line of treatment, was associated with a surprising median OS. Clinical trial information: NCT00609401.

8517 Background: Standard front-line chemotherapy for advanced MPM is (Pem and a platinum; optimal treatment duration is unknown. We performed a randomized phase 2 trial (NCT01085630) to determine if continuation of single-agent Pem after 4-6 cycles of Pem-platinum would improve progression-free survival (PFS). Methods: Eligible pts had histologically confirmed unresectable MPM, and performance status (PS) 0-1. Pts with at least stable disease following 4-6 cycles of Pem-platinum were stratified by first-line regimen (cis- or carboplatin) and histology (epithelioid versus other) and randomized 1:1 to Obs or continuation of Pem until progression. The primary endpoint was PFS. We assumed that Obs produced a median (m) PFS of 3 months (mo) and Pem would yield a 100% improvement in mPFS to 6 mo; 60 eligible pts (30 per arm) were to be randomized. Results: 72 pts from 30 sites registered 12/10-6/16. The study closed early due to slow accrual once 53 pts were randomized; 49 eligible pts (22 Obs, 27 Pem) are included in the efficacy analysis. Pt characteristics (Obs/Pem): age: median (range) 70 (39-85)/70 (52-87); male 68%/78%; PS 0 27%/33%; epithelioid histology 77%/70%; first-line cisplatin 27%/26%. A median of 4 cycles of Pem (range 1-33) was delivered; 22% of pts required dose modification. mPFS was 3 mo on Obs and 3.4 mo on Pem (hazard ratio (HR) 0.99; 95% CI: 0.51-1.90; p=0.9733). Median overall survival (mOS) was 11.8 mo for Obs, and 16.3 mo for Pem (HR 0.86; 95% CI 0.44-1.71; p=0.6737). Toxicities ≥ grade 3 on Pem included anemia 8%, lymphopenia 8%, neutropenia 4%, and fatigue 4%; there were no grade 5 toxicities. A higher baseline level of serum mesothelin related peptide (SMRP) was associated with worse PFS (HR 1.861, p=0.049). Baseline osteopontin did not significantly affect PFS (p=0.3630). Conclusions: Although it was well tolerated, maintenance Pem following initial Pem/platinum doublet chemotherapy does not improve PFS in MPM patients. High baseline SMRP was associated with shorter PFS. Support: U10CA180821, U10CA180882; https://acknowledgments.alliancefound.org . Clinical trial information: NCT01085630.

Background Lenvatinib is approved as first-line treatment for patients with advanced hepatocellular carcinoma (HCC). The efficacy of lenvatinib in Caucasian real-world patients is insufficiently defined. The purpose of this study was to evaluate the efficacy of lenvatinib in a multi-center cohort (ELEVATOR) from Germany and Austria. Methods A retrospective data analysis of 205 patients treated with first-line systemic lenvatinib at 14 different sites was conducted. Overall survival, progression free survival, overall response rate and adverse event rates were assessed and analyzed. Results Patients receiving lenvatinib in the real-world setting reached a median overall survival of 12.8 months, which was comparable to the results reported from the REFLECT study. Median overall survival (mOS) and progression free survival (mPFS) was superior in those patients who met the inclusion criteria of the REFLECT study compared to patients who failed to meet the inclusion criteria (mOS 15.6 vs 10.2 months, HR 0.55, 95% CI 0.38-0.81, p=0.002; mPFS 8.1 vs 4.8 months HR 0.65, 95% CI 0.46-0.91, p=0.0015). For patients with an impaired liver function according to the Albumin-Bilirubin (ALBI) grade, or reduced ECOG performance status ≥2, survival was significantly shorter compared to patients with sustained liver function (ALBI grade 1) and good performance status (ECOG performance status 0), respectively (HR 1.69, 95% CI 1.07-2.66, p=0.023; HR 2.25, 95% CI 1.19-4.23, p=0.012). Additionally, macrovascular invasion (HR 1.55, 95% CI 1.02-2.37, p=0.041) and an AFP ≥200 ng/mL (HR 1.56, 95% CI 1.03-2.34, p=0.034) were confirmed as independent negative prognostic factors in our cohort of patients with advanced HCC. Conclusion Overall, our data confirm the efficacy of lenvatinib as first-line treatment and did not reveal new or unexpected side effects in a large retrospective Caucasian real-world cohort, supporting the use of lenvatinib as meaningful alternative for patients that cannot be treated with IO-based combinations in first-line HCC.

3620 Background: The primary and final analyses of PRIME demonstrated that pmab + FOLFOX4 significantly improved progression-free survival (PFS) vs FOLFOX4 alone for first-line treatment of patients (pts) with wild-type (WT) KRAS exon 2 mCRC. Methods: Pts were randomized 1:1 to pmab 6.0 mg/kg every 2 weeks + FOLFOX4 or FOLFOX4 alone and had no prior chemotherapy for mCRC, ECOG performance status ≤ 2, and tumor tissue for biomarker testing. The primary endpoint was PFS by central assessment. Secondary endpoints included OS, objective response rate, and safety. KRAS exon 2 tumor status was determined by a blinded central lab prior to the primary analysis. This exploratory analysis of updated survival (>80% OS events) estimated the treatment effect of pmab + FOLFOX4 compared with FOLFOX4 alone on OS by KRAS exon 2 status. Previous analyses in pts with WT KRAS exon 2 tumor status reported OS with an event rate of 54% of pts in the primary analysis and 68% of pts in the final analysis. Results: 1183 pts were randomized and received treatment: 593 pts in the pmab + FOLFOX4 arm and 590 pts in the FOLFOX4 alone arm. The KRAS exon 2 ascertainment rate was 93%, consistent with the primary analysis. 535/656 pts (82%) with WT KRAS exon 2 mCRC had an OS event at the time of this analysis. Results are shown (Table). Conclusions: In this updated analysis, an improvement in OS was observed in pts with WT KRAS exon 2 mCRC treated with pmab + FOLFOX4 vs FOLFOX4 alone (p = 0.03). Median OS was reduced in pts with mutant (MT) KRAS mCRC (p = 0.16) and is consistent with previous analyses. Updated efficacy and safety results will be presented. KRAS testing is critical to select appropriate pts with mCRC for treatment with pmab. Clinical trial information: NCT00364013. [Table: see text]

2531 Background: A direct correlation between anti–epidermal growth factor (EGF)antibody titers and survival was demonstrated in vaccinated patients with novel NSCLC advanced in Phase II studies. We show the results of treatment with anti-EGF vaccine in a cohort of patients with metastatic NSCLC after progressing to first line therapy. We evaluated immunogenicity, safety, treatment response and effect on survival. Methods: 12 patients with metastatic NSCLC after progressing to first-line therapy received anti EGF-vaccine alone or in combination with chemotherapy. Results: From October 2009 until August 2011, 12 patients started treatment with anti EGF vaccine; mean age 56.5 (42-79 y); 66.7% male; ECOG 0 and 1: 41.7% and 58,3% respectively. Adenocarcinoma (50%), bronchioloalveolar (33.3%), adenosquamous (16.7%). Metastatic sites: lung (41.7%), pleura (25%), CNS (16.7%), Kidney (8.3%). In addition to chemotherapy previous used: radiotherapy (50%), surgery (41.7%), erlotinib (41.7%), bevacizumab (25%). The 50% patients received vaccine alone. The 83.3% of patients had titers 1/4000 sera dilutions or more (good responders). According to RECIST 1.1: CR: 8.3%, PR: 16.7%, SD: 41.7%, PD 25%. Median overall survival was 18.8 months (95% CI: 13.3- 24.4 m). Median progression-free survival was 7.3 months (95% CI: 6.4 -8.2 m). We found no statistically significant differences in OS and PFS when comparing vaccine alone or combined (p = 0.181 and p = 0.801). 75% of patients had adverse effect: more frequently were: 42.4% application site pain, 15.1% fever and 10.38% chills, none of them serious. Conclusions: Vaccination anti EGF in patients with metastatic NSCLC after progressing to first line, alone or in combination, was safe and provoked an increase in anti-EGF antibody titers, produced clinical benefit, improved overall survival and progression free survival.

52 Background: Ramucirumab is approved in the USA, EU, and Japan as second-line treatment in advanced gastric or gastroesophageal junction adenocarcinoma. This agent is often used with paclitaxel, but we can use it as a single agent in second-line treatment. Because REGARD trial has shown that Ramucirumab as a single agent prolongs overall survival and progression-free survival. However, this trial doesn’t include Japanese patients, and we have no trial concerning the efficacy of Ramucirumab as third or later-line treatment up to date. We reviewed retrospectively the efficacy and safety of Ramucirumab as a single agent in our hospital. Methods: We investigated 12 cases from June (when Ramucirumab has been approved) to September. Results: The median age was 61 years old, 6 male and 6 female patients. Performance status (0/1/2) = (1/10/1) cases. (second/third/fourth or later)-lines = (4/4/4) cases. Metastatic sites are lymph node, liver, lung, bone, and peritoneum. 7 patients had gastrectomy and 5 patients of them received adjuvant chemotherapy. Response rate is 50%, median progressive-free survival is 51 days, and median overall survival is 13 months. Some patients experienced grade 1or 2 adverse events: fatigue, loss of appetite, diarrhea, and hypertension. Conclusions: We cannot say that single agent administration of Ramucirumab demonstrates good response, some patients kept stable disease in this regimen. Ramucirumab as a single agent can be an option of treatments after paclitaxel fails or when it is difficult to administrate it.

The Impact

4029 Background: The clearance of 5-FU differs significantly between men (M) and women (W). Adjuvant chemotherapy (CT) for CRC has a higher toxicity in W. The impact of sex on efficacy and toxicity in first-line trials of metastatic CRC (mCRC) is unknown. Methods: We analyzed patient (pt) and tumor characteristics, toxicities (nausea (AE1), vomiting (AE2), diarrhea, neutropenia (AE3)) and efficacy (overall survival (OS), progression-free survival (PFS)) according to sex in the following treatment groups: A: CT alone, B: CT + bevacizumab, C: CT + EGFR-antibodies, with subgroup analyses in the CT alone group for single-agent, doublets and triplets, as well as irinotecan- and oxaliplatin-based regimens. Pts from trials with treatments still used today and all relevant data available were eligible. OS and PFS were assessed using Kaplan-Meier and Cox models adjusted for primary tumor location and performance status (PS). Results: We included 28 trials with 18.399 pts (11.352 M and 7.047 W). W were younger (61 vs. 63 years), had more often a PS of 1 (49 vs 45%), BRAF mutations (10 vs. 7%), right-sided tumors (42 vs. 35%) and less often rectal tumors (26 vs. 32%). Significant differences in toxicity are reported in table. Rates of diarrhea were similar. There was no sex disparity in OS in the predefined subgroups except for pts receiving triplets where OS was better in M (HRadj=1.39 (1.05 - 1.85)). Median (interquartile range) OS in months for M and W was 16.7 (9.2-27.4) and 16.2 (8.9-27.2) in group 1, 21.9 (12.7-37.5) and 22.3 (12.9 – 39.0) in group 2, and 26.8 (14.6-45.3) and 24.8 (12.3-49.2) in group 3. HRsadj (W vs M) (95% CI), p values for OS were 1.02 (0.96-1.09), .557, 0.92 (0.83-1.03), .142, 0.99 (0.85-1.14), .866. Conclusions: M and W with mCRC differ significantly regarding patient and tumor characteristics. The significant higher toxicity in W does not translate in a higher treatment efficacy. Apart from known sex differences in pharmacokinetics of 5-FU, differences in pharmacodynamics must be postulated. [Table: see text]

HIV infection is an exclusion criterion in lung cancer trials. This multicentre phase II trial aimed to assess feasibility, efficacy and safety of first-line carboplatin plus pemetrexed (CaP) followed by pemetrexed (P) maintenance in people living with HIV (PLHIV) with advanced non-squamous non-small cell lung cancer (NS-NSCLC).Four cycles of CaP were followed by P-maintenance therapy in patients with Eastern Cooperative Oncology Group performance status ≤2. The primary objective was a disease control rate (DCR) ≥30% after 12 weeks.Of the 61 PLHIV enrolled, 49 (80%) had a performance status of 0–1, and 19 (31%) had brain metastases. Median CD4 lymphocyte count was 418 cells·µL−1 (range 18–1230), median CD4 lymphocyte nadir was 169.5 cells·µL−1 (1–822); 48 (80%) patients were virologically controlled. Four-cycle inductions were achieved by 38 (62%) patients, and 31 (51%) started P-maintenance (median of 4.1 cycles (range 1–19)). The 12-week DCR was 50.8% (95% CI 38.3–63.4) and partial response rate 21.3%. Median progression-free survival and overall survival were 3.5 (95% CI 2.7–4.4) and 7.6 months (5.7–12.8), respectively. Patients with a performance status of 0–1 had the longest median progression-free survival (4.3 months, 95% CI 3.1–5.2) and overall survival (11.9 months, 95% CI 6.4–14.3). During induction, CaP doublet was well tolerated apart from grade 3–4 haematological toxicities (neutropenia 53.8%; thrombocytopenia 35.0%; anaemia 30.0%). Two fatal treatment-related sepses were reported. No opportunistic infections were experienced.In PLHIV with advanced NS-NSCLC, first-line four-cycle CaP induction followed by P-maintenance was effective and reasonably well-tolerated. Further studies should evaluate combination strategies of CaP with immunotherapy in PLHIV.

Introduction Soft tissue sarcomas are a heterogeneous and rare group of cancers with a short median overall survival despite the chemotherapy. Pazopanib has approval for the treatment of advanced soft tissue sarcoma. We aimed to investigate the clinical outcomes of Turkish patients with advanced soft tissue sarcoma who received pazopanib. Patients and methods This was a retrospective study. The inclusion criteria were: ≥18 years of age, having histologically proven advanced soft tissue sarcoma and receiving pazopanib at least one day. Results A total of 79 patients were assessed in this study. The median age was 49.6 years. The average dose intensity of pazopanib was 767 mg (400–800). The median duration of pazopanib treatment was 6.11 months. Fourteen patients (17.7%) used pazopanib at first line for advanced soft tissue sarcomas. The most common cause of discontinuation of pazopanib was the progression of the disease (89.6%). Pazopanib was well tolerated. The most common grade ≥3 side effect was anemia. The most common grade ≤2 side effects were anemia and hyperbilirubinemia. The median progression-free survival, overall survival, and follow-up were 3.97 months, 11.40 months, and 32.72 months, respectively. Female gender, good performance status, and the presence of pazopanib-induced hypothyroidism were associated with longer progression-free survival. Also, good performance status and being a responder to first-line treatment were associated with longer overall survival. Conclusions We showed that pazopanib was well tolerated and had clinical benefit in patients with advanced soft tissue sarcoma in a Turkish cohort. This is the first study that suggests pazopanib-induced hypothyroidism may act as a predictive marker for better outcomes in patients with advanced soft tissue sarcoma.

Purpose RAS mutations predict lack of response to epidermal growth factor receptor monoclonal antibody therapy in patients with metastatic colorectal cancer (mCRC), but preclinical studies and retrospective clinical data suggest that patients with tumors harboring the exon 2 KRAS G13D mutation may benefit from cetuximab. We aimed to assess cetuximab monotherapy and cetuximab plus irinotecan in patients with molecularly selected (G13D mutation) chemotherapy-refractory mCRC in a randomized phase II trial of this rare molecular subtype. Patients and Methods Patients with chemotherapy-refractory KRAS G13D mutation–positive mCRC who had progressed within 6 months of irinotecan therapy were randomly assigned to cetuximab 400 mg/m2 loading dose and then 250 mg/m2 once per week with or without irinotecan 180 mg/m2 once every 2 weeks. The primary end point was 6-month progression-free survival; secondary end points were response rate, overall survival, quality of life, and toxicity. Results Fifty-one of 53 patients recruited over 2 years were eligible. The 6-month progression-free survival rate was 10% (95% CI, 2% to 26%) for cetuximab versus 23% (95% CI, 9% to 40%) for cetuximab plus irinotecan with a hazard ratio of 0.74 (95% CI, 0.42 to 1.32). Response and stable disease rates were 0% and 58% for monotherapy versus 9% and 70% for combination treatment, respectively. Overall survival and quality of life were similar; toxicities were higher with combination therapy. Conclusion In patients with G13D-mutated chemotherapy-refractory mCRC, there was no statistically significant improvement in disease control at 6 months with either cetuximab monotherapy or cetuximab plus irinotecan. No responses were seen with single-agent cetuximab. The responses observed with the combination of cetuximab and irinotecan may reflect true drug synergy or persistent irinotecan sensitivity. The ICECREAM (Irinotecan Cetuximab Evaluation and Cetuximab Response Evaluation Among Patients with a G13D Mutation) study demonstrates the need to prospectively evaluate hypotheses that were previously supported by retrospective analyses and exemplifies the value of international collaboration in trials of rare molecular subtypes.
