TPS787 Background: Imprime PGG (Imprime) is a novel immune modulator (complex carbohydrate biologic), which harnesses innate immune cells to enhance killing of antibody-targeted tumor cells. In a phase 2 single-arm clinical trial in mCRC, the combination of Imprime with cetuximab resulted in 24% ORR, 62% disease control rate (DCR), and median time to progression (TTP) of 12 wks (Tamayo ME, Ann Onc 2010), representing approximate 100% increases vs historical control (Cunningham, NEJM 2004). ORR was 45%, DCR, 82% and TTP, 24 wks in pts with KRAS WT tumors (post hoc analysis). Single-agent cetuximab has been shown to improve objective response rate (ORR), progression-free survival (PFS) and overall survival (OS) in patients (pts) with epidermal growth factor receptor (EGFR) expressing, KRAS wild-type (WT) metastatic colorectal cancer (mCRC) who failed oxaliplatin- and irinotecan-based therapy or are intolerant to irinotecan. The mechanism of action of cetuximab is thought to rely on competitive blockade of endogenous ligand binding and downstream signaling, internalization and down regulation of EGFR, as well as antibody-dependent cellular cytotoxicity (ADCC) (Erbitux SmPC). The current trial, sponsored by Biothera (registered with ClinicalTrials.gov NCT01309126) is to confirm these findings in phase 3. Methods: Eligible pts will have had prior oxaliplatin- and irinotecan-based therapy or be intolerant to irinotecan, and will meet key inclusion criteria including measurable disease and ECOG performance status of 0 or 1. In a 2:1 randomization, stratified by geographic region, prior chemotherapy and site, approximately 795 pts will receive weekly open-label Imprime plus cetuximab or cetuximab alone. The primary endpoint of the study is OS and primary analysis will occur when ~709 deaths have occurred. Secondary endpoints include PFS, ORR (based on RECIST 1.1), quality of life, safety and pharmacokinetics. Exploratory endpoints include biomarker analyses. Pt screening and enrollment is underway in the United States and Europe. Clinical trial information: NCT01309126.

TPS3618 Background: Both anti-EGFR and anti-VEGF therapies have shown clinical benefit when they are added in first and second-line in L-sided CRC. The conflicting results in anti-VEGF vs. anti-EGFR studies (FIRE-3, PEAK and CALGB/SWOG 80405 studies) suggest that the sequence of targeted therapies added to FOLFOX or FOLFIRI regimens in first- and second-line treatment could be an important factor in the overall survival (OS) of mCRC patients. Currently, there are no randomized data on the sequential use of an anti-EGFR followed by an anti-VEGF or vice versa. Therefore, the aim of this randomized clinical trial is to compare the efficacy of two treatment sequences, panitumumab followed by bevacizumab versus bevacizumab followed by panitumumab in combination with FOLFOX chemotherapy in first-line and with FOLFIRI in second-line in patients with wild-type RAS, primary L-sided, metastatic colorectal cancer (mCRC). Methods: A phase III, multicentre, open-label and randomized two-arm clinical trial. Untreated patients with wild-type RAS mCRC (determined locally), primary L-sided and unresectable will be screened for this trial. Eligible patients will be randomized 1:1 to receive first-line (1L) panitumumab plus FOLFOX and then bevacizumab plus FOLFIRI as second-line (2L) treatment (Seq. 1) or bevacizumab plus FOLFOX as 1L and then panitumumab plus FOLFIRI as 2L treatment (Seq. 2). Randomization will be stratified by number of metastatic organs involved (1 vs > 1). Primary objective is the comparison of the progression free survival (PFS) rate at 35 months (m) of Seq 1 vs Seq. 2. Secondary objectives: PFS from randomization to 2nd progression or death, OS rate at 35 months and OS of Seq. 1 vs Seq. 2; PFS, objective response rate, disease control rate, early tumour shrinkage, Depth of Response, duration and time to response and safety in 1L treatment and in 2L treatment in each Sequence arm. Exploratory objectives: impact of baseline biomarkers predictive of the efficacy in each Sequence arm and the clinical impact of clonal dynamics by longitudinal analysis of circulating tumour deoxyribonucleic acid (ctDNA) in plasma. The trial is in progress; 28 of up to 370 planned patients have been recruited at the end of January 2019 (first patient in 31 October 2018). Clinical trial information: NCT03635021.

14528 Background: Cetuximab ( C ) has demonstrated activity both as a single agent and in combination with irinotecan (CPT11) in patients (pts) with metastatic colorectal cancer (mCRC) expressing epidermal growth factor receptor (EGFR) refractory to CPT 11 and oxaliplatin based chemotherapy. This European retrospective study explored the tolerability and activity of C combined with CPT 11 in an unselected population of elderly pts with CPT11- refractory mCRC Methods: 67 pts with mCRC aged = 70 yrs were treated with C (400 mg/m2 loading dose over 2 hours, then 250 mg/m2 over 1 hour weekly). C was given alone (2 pts), combined with CPT11 (56 pts) or CPT11 + 5FU-LV as conventional (4 pts) or chronomodulated delivery (5 pts). Treatment was administered as 2nd to 6th line. Primary endpoint was time to tumor progression (TTP). Secondary endpoints were toxicity, objective response rate (RR) (with RECIST Criteria) and overall survival (OS). Results: Median age was 77 yrs (70–84); M/F: 44/23; WHO performance status 0/1/2/unknown: 12/40/11/4; EGFR expression: + in 55 pts, - in 2 pts and unknown in 10 pts; colon/rectum/unknown: 49/14 /4. More frequent toxicities included acneiform skin rash, which occurred in 33 pts (Grade (G) 2: 24 pts, 35%; G3: 9 pts, 13%), diarrhea (G3, 11 pts, 16%; G4, 2 pts, 3%) and neutropenia (G3: 4 pts, 6%; G4: 5 pts, 7%). RR was 23% including 1 complete and 14 partial responses. Disease control rate (RR + stable disease) was 53%. No correlation was found between skin rash and response. Median TTP (intent-to treat) was 4.5 months [95% CI: 3.2 - 5.7]. Median OS was 15 months [12.0–17.9]. Conclusions: The combination of C with CPT11-based chemotherapy resulted in good activity and acceptable tolerability in elderly patients with heavily pre-treated mCRC, comparable to that of the younger patients. This treatment option can be reasonably proposed to the elderly population. No significant financial relationships to disclose.

Trial Participants

524 Background: Guidelines recommend that oncology patients have the opportunity to participate in a clinical trial wherever possible. It is purported that as trial participants are often younger and fitter, data extrapolation from trial outcomes to patients seen in routine care may be difficult. We compared characteristics of patients with metastatic colorectal cancer (mCRC) participating in a first-line clinical trial with those treated in routine care. Methods: The TRACC (Treatment of Recurrent and Advanced Colorectal Cancer) database, a clinician-designed mCRC comprehensive database, was used to identify patients treated on a first-line trial compared with those receiving combination chemotherapy; single-agent therapy; or no chemotherapy. Data collection began in June 2009 and is ongoing at 15 Australian centres to date. Results: Of 671 patients, 49 (7.3%) participated in a first-line clinical trial. Patients on trial were significantly younger, with 49% (n=24) trial participants being under 60 years, compared with 33% (n=128) receiving combination chemotherapy off study (p=0.047), 13% (n=13) single-agent therapy (p<0.0001) and 10% (n=15) no treatment (p<0.0001). All trial participants were ECOG performance status 0-1, compared with 87% (n=335) of non-trial patients receiving combination chemotherapy (p<0.0001), 80% (n=82) receiving single-agent therapy (p<0.0001) and 52% (n=76) no treatment (p<0.0001). Similarly, Charlson comorbidity score was significantly lower in trial participants, with 88% (n=43) having a score 0-3 (less comorbidity) versus 71% (n=272) receiving combination chemotherapy, 39% (n=40) receiving single-agent therapy and 25% (n=36) no treatment. Preliminary analysis suggests significant overall survival benefit for the clinical trial cohort. Conclusions: Consistent with available literature, trial participants with mCRC are significantly younger, fitter and of better performance status than those who receive similar chemotherapy off-trial or no treatment. The impact of trial participation on survival may be thus subject to multiple factors biasing for a better outcome, including the contributing benefit of younger age and less comorbidity.

e15039 Background: A Phase 3 clinical trial (RECOURSE) showed that trifluridine/tipiracil (FTD/TPI) was effective in the treatment of refractory metastatic colorectal cancer (mCRC) (Mayer et al. NEJM 2015;372:1909-19). An expanded-access program (EAP) for patients with refractory mCRC assessed FTD/TPI safety in a real-world setting. One limitation of RECOURSE was the small number of African-American (AA) patients enrolled in the study (n=8). The EAP enrolled 45 AA patients, enabling assessment of FTD/TPI safety in this population. Methods: Patients aged ≥18 years with refractory mCRC resistant to ≥2 regimens of standard chemotherapy and an ECOG performance status of 0 or 1 were enrolled in this open-label EAP. Patients received FTD/TPI 35 mg/m2 twice daily for 5 days followed by 2 days’ rest repeated twice followed by 14 days’ rest over a 28-day treatment cycle until drug discontinuation. We investigated duration of exposure to FTD/TPI and associated adverse events (AEs) in AA patients to compare them with non-AA and US patients from RECOURSE. Results: Median duration of FTD/TPI therapy for AA patients in the EAP was 9.7 weeks, similar to non-AA patients in the EAP (9.7 weeks) and US patients in RECOURSE (8.9 weeks) (differences not statistically significant). 73.3% of AA patients (n=33) in the EAP discontinued treatment due to disease progression and 8.9% (n=4) discontinued due to AEs. AEs related to FTD/TPI are summarized in the table. Conclusions: Lung cancer patients in Eastern North Carolina possess a strikingly poor inflammatory signature with significant implications for quality of life and survival. Clinical trial information: NCT02286492. [Table: see text]

Background: The optimal anti-angiogenic strategy as second-line treatment in RAS wild-type metastatic colorectal cancer (mCRC) treated with anti-EGFR (Epidermal Growth Factor Receptor) based first-line treatment is still debated. Methods: This multicenter, real-world, retrospective study is aimed at evaluating the effectiveness of second-line Bevacizumab- and Aflibercept-based treatments after an anti-EGFR based first-line regimen. Clinical outcomes measured were: objective response rate (ORR), progression free survival (PFS), overall survival (OS) and adverse events (AEs) profiles. Results: From February 2011 to October 2019, 277 consecutive mCRC patients received Bevacizumab-based (228, 82.3%) or Aflibercept-based (49, 17.7%) regimen. No significant difference was found regarding ORR. The median follow-up was 27.7 months (95%CI: 24.7–34.4). Aflibercept-treated group had a significantly shorter PFS compared to Bevacizumab-treated group (5.6 vs. 7.1 months, respectively) (HR = 1.34 (95%CI: 0.95–1.89); p = 0.0932). The median OS of the Bevacizumab-treated group and Aflibercept-treated group was 16.2 (95%CI: 15.3–18.1) and 12.7 (95%CI: 8.8–17.5) months, respectively (HR= 1.31 (95%CI: 0.89–1.93) p = 0.16). After adjusting for the key covariates (age, gender, performance status, number of metastatic sites and primary tumor side) Bevacizumab-based regimens revealed to be significantly related with a prolonged PFS (HR = 1.44 (95%CI: 1.02–2.03); p = 0.0399) compared to Aflibercept-based regimens, but not with a prolonged OS (HR = 1.47 (95%CI: 0.99–2.17); p = 0.0503). The incidence of G3/G4 VEGF inhibitors class-specific AEs was 7.5% and 26.5% in the Bevacizumab-treated group and the Aflibercept-treated group, respectively (p = 0.0001). Conclusion: Our analysis seems to reveal that Bevacizumab-based regimens have a slightly better PFS and class-specific AEs profile compared to Aflibercept-based regimen as second-line treatment of RAS wild-type mCRC patients previously treated with anti-EGFR based treatments. These results have to be taken with caution and no conclusive considerations are allowed.

Abstract Background Patients with chemotherapy refractory metastatic colorectal cancer (CRC) have a poor prognosis and limited therapeutic options. In this phase Ib/II clinical trial, we established the maximum tolerated dose (MTD) and recommended phase II dose (RPTD) for the combination of capecitabine and ziv-aflibercept, and then we evaluated the efficacy of the combination in patients with chemotherapy refractory metastatic CRC. Methods All patients were required to have a Karnofsky Performance Status > 70% and adequate organ function. The phase Ib dose escalation cohort included patients with advanced solid tumors who had progressed on all standard therapies. Using a standard 3 + 3 design, we identified the MTD and RPTD for the combination. Fifty patients with metastatic CRC who had progressed on or were intolerant of a fluoropyrimidine, oxaliplatin, irinotecan, and bevacizumab were then enrolled in a single-arm phase II expansion cohort, and were treated at the RPTD. Prior EGFR antibody therapy was required for subjects with RAS wildtype tumors. The primary endpoint for the expansion cohort was progression-free survival (PFS) at two months. Secondary endpoints included objective response rate (ORR) and overall survival (OS). Results A total of 63 patients were enrolled and evaluable for toxicity (13 dose escalation; 50 expansion). The MTD and RPTD were: capecitabine 850 mg/m2, P.O. bid, days 1–14, and ziv-aflibercept 6 mg/kg I.V., day 1, of each 21-day cycle. In the expansion cohort, 72% of patients were progression-free at two months (95% confidence interval [CI], 60–84%). Median PFS and OS were 3.9 months (95% CI, 2.3–4.5) and 7.1 months (95% CI: 5.8–10.0), respectively. Among all patients evaluable for toxicity, the most common treatment related adverse events (all grade [%]; grade ≥ 3 [%]) included palmar-plantar erythrodysesthesia (41%; 6%), hypertension (33%; 22%), and mucositis (19%; 5%). RNA was isolated from archived tumor specimens and gene expression analyses revealed no association between angiogenic biomarkers and clinical outcomes. Conclusion The combination of capecitabine and ziv-aflibercept at the RPTD demonstrated acceptable safety and tolerability. PFS at 2 months in patients with chemotherapy refractory metastatic CRC was significantly greater than that in historical controls, indicating that this combination warrants further study. Trial registration This clinical trial was registered in the www.clinicaltrials.gov system as NCT01661972 on July 31, 2012.

Study Intervention

BackgroundPlatinum-based regimens, such as FOLFOX (fluorouracil [5-FU], leucovorin, oxaliplatin), are recommended standard of care first-line options in metastatic colorectal cancer (CRC). Maintenance therapy with a less intensive treatment regimen in metastatic CRC patients who do not progress during intensive first-line platinum–based induction therapy can enhance clinical benefit and reduce toxicity associated with long-term exposure to oxaliplatin. The phase 3 CAIRO3 study demonstrated PFS benefit and a trend toward OS benefit in patients who discontinued oxaliplatin and switched to a maintenance regimen of fluoropyrimidine and bevacizumab. Olaparib is an oral PARP inhibitor that has shown efficacy in platinum-sensitive cancers. LYNK-003 is a randomized, open-label, phase 3 trial evaluating the efficacy and safety of olaparib, alone or in combination with bevacizumab, compared with bevacizumab plus 5-FU in patients with unresectable or metastatic CRC that has not progressed following first-line induction with FOLFOX plus bevacizumab.MethodsAdult (≥18 years) patients with histologically confirmed unresectable or metastatic CRC that has not progressed following a first-line induction course of ≥6 cycles of FOLFOX plus bevacizumab and who can no longer tolerate oxaliplatin are eligible. Patients are required to have ECOG performance status score 0–1, adequate organ function, and provide tumor tissue for biomarker analysis. Patients will be randomly assigned 1:1:1 to olaparib 300 mg twice-daily (BID) plus bevacizumab 5 mg/kg every 2 weeks (Q2W), olaparib 300 mg BID, or 5-FU 2400 mg/m2 over 46–48 hours Q2W plus bevacizumab 5 mg/kg Q2W. Treatment will be stratified according to response to prior FOLFOX plus bevacizumab induction (stable disease [SD] vs partial response [PR]/complete response [CR]), mutation status (BRAFmut and/or Rasmut vs BRAFwt plus Raswt), and number of cycles of prior FOLFOX plus bevacizumab induction (6–8 vs >8 cycles). Responses will be assessed by computed tomography/contrast-enhanced magnetic resonance imaging per RECIST 1.1 by blinded independent central review (BICR) every 8 weeks during the first year and every 12 weeks thereafter. Study treatments will continue until documented progressive disease, unacceptable toxicity, intercurrent illness that prevents further administration of study intervention, investigator’s decision to discontinue the patient, consent withdrawal, pregnancy, or administrative reasons requiring cessation of study intervention. The primary endpoint is PFS per RECIST 1.1 by BICR and the key secondary endpoint is OS. Additional secondary endpoints are objective response rate and duration of response; safety and tolerability will also be reported. Approximately 525 patients will be enrolled.ResultsN/AConclusionsN/AAcknowledgementsThe authors thank the patients and their families for participating in these trials and all investigators and site personnel.
