Background Combination nivolumab and ipilimumab is approved for the first-line treatment of patients with advanced melanoma in several jurisdictions (United States, European Union, and Canada). CheckMate 218 is a North American expanded access program (EAP) of nivolumab plus ipilimumab in patients with advanced melanoma. We report safety and survival outcomes of the Canadian cohort in this EAP.Methods Eligible patients were aged ≥18 years with unresectable stage III or stage IV melanoma, an Eastern Cooperative Oncology Group performance status of 0 or 1, and no prior anti–PD-1 or anti–CTLA-4 therapy. Patients were treated with nivolumab 1 mg/kg combined with ipilimumab 3 mg/kg every 3 weeks for 4 cycles (induction phase) and then continued with nivolumab 3 mg/kg every 2 weeks (maintenance phase) until progression, unacceptable toxicity, or a maximum of 48 weeks, whichever occurred first. Safety and overall survival (OS) data were collected.Results A total of 194 patients were enrolled; 174 were treated, and 51% continued on nivolumab maintenance. The median follow-up time was 12.9 months. All-grade and grade 3–4 treatment-related adverse events were reported in 98% and 60% of patients, respectively, and led to treatment discontinuation in 40% and 28% of patients, respectively. Two treatment-related deaths were reported. Twelve- and 18-month OS rates were 80% (95% confidence interval [CI]: 73 to 86) and 76% (95% CI: 67 to 82), respectively.Conclusion In this Canadian population, nivolumab plus ipilimumab demonstrated a safety profile and survival outcomes consistent with phase 2 and 3 clinical trial data.Trial registration: NCT02186249

e15007 Background: The CORRECT trial demonstrated overall survival benefits of regorafenib monotherapy in patients with metastatic colorectal cancer (CRC) who were refractory to prior chemotherapy and biological therapy. However, stringent criteria used to determine treatment eligibility in the trial setting may limit its external validity in the real world. We aimed to examine treatment attrition rates and eligibility of regorafenib in routine clinical practice. Methods: All patients diagnosed with metastatic CRC between 2009 and 2014 who received 2 or more lines of systemic therapy at the British Columbia Cancer Agency were identified. During the study timeframe, cetuximab (cmab) and panitumumab (pmab) were only used in the chemo-refractory setting. Data on clinical factors, pathological variables and outcomes were ascertained and analyzed. Eligibility was defined based on criteria outlined in the CORRECT trial. Results: A total of 391 patients were included among whom only 39% were considered eligible for regorafenib. Median age was 61 (range 22-84) years. 247 (63%) were men, 305 (78%) were Caucasian, and 237 (60%) had a colonic primary. The disease burden at diagnosis was high: 267 (81%) had lymph node involvement, and 225 (59%) had distant metastases. In patients previously treated with cmab, main reasons for regorafenib ineligiblity were Eastern Cooperative Oncology Group performance status (ECOG PS) > 1 (26.9%), aspartate aminotransferase (AST) > 2 x upper limit of normal (ULN) (6.5%), and arterio-venous thrombotic or embolic events in the preceding 6 months (6.5%). In the group treated with pmab previously, main reasons for ineligibility were ECOG PS > 1 (46.6%), total bilirubin > 1.5 x ULN (14.1%), and thrombotic or embolic events in the past 6 months (5.7%). Additional analyses showed that regorafenib-eligible patients had increased median overall survival compared to ineligible patients (44.0 vs 37.1 months, P= 0.028). Conclusions: The strict trial eligibility criteria disqualified the majority of real world patients with metastatic CRC for regorfenib. As ineligibility predicts poorer outcomes, trials aimed at serving protocol-ineligible patients are warranted.

188 Background: Abiraterone or enzalutamide are licensed for use post-docetaxel in metastatic castrate resistant prostate cancer (mCRPC). Both target the androgen receptor signalling pathway. There is little information describing their sequential use. Methods: Patients with mCRPC who had failed treatment with docetaxel and abiraterone received enzalutamide as part of an expanded access program. Patients were reviewed four weekly and post-treatment PSA used to determine efficacy. Results: Twenty three patients, median age 76 (range, 65 to 82), performance status of 1 (15/23) or 2 (8/23) with mCRPC (22/23 bone and 4/23 visceral disease) were enrolled. All had received prior docetaxel and abiraterone as well as cabazitaxel (35%), dexamethasone (30%), and stillboestrol (52%). Median biochemical progression free survival (bPFS) was 11.9 weeks. Nine (39%) patients showed sensitivity to enzalutamide, defined as a greater than 50% reduction in PSA. There was a correlation between PSA response to abiraterone and enzalutamide (R=0.45, p=0.03). In 10 out of 23 and 13 out of 23 patients who were sensitive and insensitive to abiraterone, 60% and 23% had a great than 50% reduction in PSA, respectively. There was a trend to improved bPFS in those sensitive to abiraterone (15.7 vs. 11.4 weeks, p=0.40) and in those who showed any PSA response to abiraterone (15.9 vs. 5.3 weeks, p=0.06). Conclusions: Enzalutamide has activity following failure of docetaxel and abiraterone in mCRPC. The effectiveness is more pronounced in those who have responded to abiraterone.

9523 Background: The phase 3 IMspire150 study showed that first-line A+V+C improved investigator-assessed PFS vs placebo (P)+V+C in BRAFV600E/K mutation–positive advanced melanoma (hazard ratio 0.78; P=.0249). Prior biomarker analyses showed that IFN-g or TMB > 10 mut/Mb were associated with greater PFS benefits with A+V+C (Lewis et al. J ImmunoTher Cancer 2020;8:A188-A189). We further evaluated the association of these biomarkers with outcomes. Methods: Exploratory recursive partitioning analysis (RPA) was used to model associations between PFS and age ( < 65 vs ≥65 y), Eastern Cooperative Oncology Group performance status (0 vs 1), liver metastases (yes vs no), metastatic sites (≤3 vs > 3), sum of longest tumor diameters ( < 44 mm vs ≥44 mm), baseline LDH (normal [n] vs elevated [e]), TMB ( < 10 vs ≥10 mut/Mb), PD-L1 (negative vs positive), and IFN-g (high [h; > Quartile 3; Q3] vs intermediate [ > Q1 and ≤Q3] vs low [≤Q1]). Time-to-event analyses were summarized using Kaplan-Meier estimates. Results: The RPA analysis included 208/256 (81.3%) patients (pts) from the A+V+C arm of IMspire150 for whom LDH, TMB, IFN-g, and PD-L1 data were available. RPA showed that LDH was associated with PFS. In pts treated with A+V+C and n-LDH, h-IFN-g signature was associated with longer PFS and higher rates of objective response (OR) and complete response (CR) vs low/intermediate (l/i) IFN-g (2-y PFS: 59% vs 38%; ORR: 77% vs 69%; CR: 38% vs 15%, respectively); TMB ≥10 mut/Mb was associated with more favorable outcomes in pts with e-LDH (Table). In contrast, neither IFN-g nor TMB discriminated PFS outcomes in n-LDH or e-LDH pt subgroups receiving P+V+C. Pts with e-LDH and TMB < 10 mut/Mb had poor PFS outcomes, with 2-y PFS rates of 9% and 3% and lower rates of OR (51% and 62%) and CR (5% and 9%) in the A+V+C and P+V+C arms, respectively. Similar trends were observed for duration of response (DOR), and for the subset of pts with BRAFV600E mutation–positive melanoma. A+V+C improved PFS vs P+V+C across all subgroups with the exception of e-LDH and TMB < 10. Conclusions: IFN-g and TMB discriminated PFS benefit in pts receiving A+V+C but not for those receiving P+V+C. Durable responses were observed for pts treated with A+V+C in the n-LDH + h-IFNg subgroups.[Table: see text]

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]

59 Background: Historically, the prognosis of advanced melanoma has been poor. Recent landmark studies (KEYNOTE-006, CheckMate 066, CheckMate 037 and CheckMate 067) have shown significant improvement in outcomes of patients with advanced melanoma treated with ICIs. In a single institution retrospective study, we evaluated the efficacy and toxicities of ICIs in patients with advanced melanoma treated in real-world clinical practice. Methods: We included patients who received pembrolizumab (PEMBRO), nivolumab (NIVO), or ipilimumab plus nivolumab (IPI/NIVO) at the University of Rochester Medical Center from June 2015 to December 2018. Patient- and cancer-related characteristics were collected and compared between treatment groups. Outcomes including duration of treatment, response rates, and adverse events (AEs) were captured. Progression free survival (PFS) and overall survival (OS) were summarized using the Kaplan-Meier method. Results: We included 89 patients (55 received PEMBRO, 20 received NIVO, and 14 received IPI/NIVO); median age at ICI initiation was 68 years (range, 28-92) and 29% had Eastern Cooperative Oncology Group Performance Status (ECOG PS) of ≥2. Forty-five patients (51%) had ≥2 co-morbidities. Nine patients (10%) had autoimmune diseases prior to initiating ICIs and 34 patients (38%) had brain metastasis. ICIs were given as first line in 71 patients (80%). Compared to those who received PEMBRO or NIVO, patients who received IPI/NIVO were younger (median age was 61 vs.71 vs. 70, p=0.003) and had better ECOG PS (ECOG PS ≥2 was 0% vs. 40% vs. 33%, p=0.007). Table shows the outcomes for the three groups. Conclusions: Patients with advanced melanoma treated with ICIs derived similar response rates to those seen in published landmark studies. However, median OS was shorter (range was 38 months to not reached in published studies). [Table: see text]
