e21507 Background: Clinical data on PD-1 inhibitor combined with interferon in metastatic melanoma treatment were still limited. The objective of this study was to assess the efficacy and safety of PD-1 inhibitor/interferon-α1b combination therapy for Chinese metastatic melanoma patients in the real world. Methods: We reviewed patients diagnosed as metastatic melanoma and had received PD-1 inhibitor (pembrolizumab, 2 mg/kg, every 3 weeks, intravenously or toripalimab 240mg every 2 weeks, intravenously) combined with interferon-α1b(10μg/kg, every other day, subcutaneously) in Xijing Hospital from Dec 2018 to Nov 2020. Efficacy and safety profiles were evaluated using Response Evaluation Criteria in Solid Tumors version 1.1 and Common Terminology Criteria for Adverse Events version 5.0, respectively. Results: In total 65 patients were reviewed in this study, including 13 cases with ECOG performance status ≥2. Acral and mucosal cases accounted for 47.7% and 23.1% respectively. In 27(41.5%) patients, the combination therapy was used as the first line treatment, whereas in the rest 38 patients as second or subsequent lines. The median follow-up period was 8 months (1.5-21 months). Median OS was 15 months (95CI%: 10.62-19.38 months). Median PFS was 6 months (95CI%: 2.54-9.46 months). 6-month and 1-year PFS rate were 48.1% and 35.3%. 6-month and 1-year OS rate were 80.9% and 59.8%. Objective response was seen in 18.46% cases, with 12.31% of patients exhibiting ongoing response. The best confirmed disease control rate was 73.85%. Multivariate analysis demonstrated that overall survival was significantly associated with ECOG performance status ≥2 (OR=3.32，95%CI=1.14-9.66 ), regardless of age(≥65), elevated LDH, PD-1 inhibitor type and the line of the combination therapy. Select treatment related AEs (TRAEs) of any grade were observed in 57(87.69%) patients. The leading 3 TRAEs were lymphopenia, fatigue and fever. Grade 3 to 4 TRAEs were recorded in 2 cases. Grade 4 hyponeutrophilia occurred in a patient with ECOG status 3 using interferon-α1b plus toripalimab and resulted in discontinuation of both PD-1 inhibitor and IFN-α1b. Grade 3 headache was reported by one patient using interferon-α1b plus pembrolizumab and was solved with celecoxib 200mg daily. No drug-related deaths were reported. Conclusions: PD-1 inhibitor combining interferon-α1b therapy shows promising efficacy and acceptable toxicity in this real-world cohort of Chinese metastatic melanoma patients.[Table: see text]

e14144 Background: There is little real-world evidence evaluating treatment patterns and outcomes with IO therapies for pts with advanced melanoma (aMEL). We present results from the OPTIMIzE (NCT02780089) study in pts with aMEL receiving IO therapies. Methods: OPTIMIzE is a US-based multisite (150 sites), community-based study of adult pts with aMEL. Pts receiving first-line (1L) nivolumab (NIVO)+ipilimumab (IPI), anti-PD-1 (NIVO/pembrolizumab), or IPI between 2011-2018 with a minimum 1 y of follow-up were included. Baseline characteristics, objective response rate (ORR), overall survival (OS), treatment-related adverse events (TRAEs), and quality of life (QoL) were analyzed. QoL assessments included the Functional Assessment of Cancer Therapy–Melanoma (FACT-M), EQ-5D index, and visual analog scale (VAS). Results: Cohort size: 81 NIVO+IPI, 147 anti-PD-1, and 16 IPI (IPI arm not included in the analysis). Overall, mean age was 64.5 y; 42% had BRAF mutation. Mean follow-up was 14.1 mo. Pts in the NIVO+IPI group were younger, had better ECOG performance status, and a higher likelihood of M1c disease and elevated LDH vs the anti-PD-1 group. ORR was higher for pts treated with NIVO+IPI vs anti-PD-1 (48% vs 33%, P= 0.08). Unadjusted 1-y OS was 78.4% for NIVO+IPI and 73.1% for anti-PD-1. In multivariate Cox model analysis, the hazard ratio for OS for NIVO+IPI vs anti-PD-1 was 0.78 (95% CI, 0.46–1.33; P= 0.36). Grade 3/4 TRAEs occurred in 53% and 22% of pts in the NIVO+IPI and anti-PD-1 groups, respectively ( P˂0.001). QoL changes from baseline were clinically meaningful for EQ-5D VAS and FACT-M in the NIVO+IPI group at 12 mo (Table). After adjusting for baseline covariates, the difference at 12 mo between NIVO+IPI vs anti-PD-1 was 6.7 ( P= 0.04) for EQ-5D VAS and 8.8 ( P= 0.02) for FACT-M. Conclusions: Safety and efficacy outcomes from this prospective real-world study are consistent with those reported in prior clinical trials in treatment-naive aMEL pts. No clinically meaningful deterioration in QoL measures was observed in either group. Clinical trial information: NCT02780089. [Table: see text]

2576 Background: Many patients treated with anti-PD-1 therapy do not show a clinical response. Preclinical studies suggest that adding hypofractionated radiotherapy (HFRT) to anti-PD1 can increase the efficacy of immunotherapy through several mechanisms including increased antigen presentation. We conducted a prospective trial testing the combination of pembrolizumab and HFRT in patients with metastatic solid tumors. Methods: This prospective single-institution phase I trial tested pembrolizumab in combination with HFRT in patients with metastatic cancers (NSCLC, melanoma, pancreas, breast, others) and an ECOG performance status of 0-1. Melanoma and NSCLC patients were required to have progression of disease on anti-PD1, having received ≥ 2 doses of anti-PD1 and progression documented by RECIST v1.1. Patients were required to have an index lesion ≥1 cm that was amenable to HFRT and at least one other lesion that was not irradiated and could be followed for response using RECIST criteria. Pembrolizumab 200 mg IV every 3 weeks was administered beginning 1 week prior to the first fraction of radiation. The HFRT dose was 8 Gy x 3 fractions or 17 Gy x 1 fraction, determined by randomization during the Expansion phase. The primary objective was the safety of HFRT combined with pembrolizumab, with dose-limiting toxicity (DLT) defined as Grade ≥ 3 non-hematological toxicity related to the combination of Pembrolizumab and HFRT. The secondary objective was the radiographic response of metastatic lesions outside the radiation field as measured by RECIST. Results: 59 patients aged 27-90 years (median 60) were enrolled from March 2015 to December 2018 (24 in the Safety Phase and 35 in Expansion Phase). 40 patients (67.7%) had treatment-related AEs, of which 4 were grade 3 and none were grade 4. One patient experienced hepatitis, classified as DLT. While most patients did not have a radiologic response, in patients with metastatic melanoma, 7 of 16 (43.8%, exact 95% CI 19.8-70.1%) had an objective response to HFRT + pembrolizumab, including 3 complete and 4 partial responses. Responses are durable with 3/3 complete responders alive with no progression, and 3/4 partial responders alive with 2 having no evidence of progression. Among melanoma patients, only 2 of 7 (29%) responders received ipilimumab prior to enrollment, compared to 8 of 9 (89%) non-responders (p = 0.035). An increase in Ki67+ PD-1+ non-naïve CD8 T-cells was observed in the blood 2 weeks after HFRT, but the magnitude did not correlate with likelihood of response. Responses were observed after either 17 Gy x 1 fraction or 8 Gy x 3 fractions, with no difference in response rate by fractionation. Conclusions: This study suggests that HFRT administered with concurrent pembrolizumab is associated with acceptable toxicity and that in patients with metastatic melanoma progressing on anti-PD-1 therapy, this approach yields an ORR of 44%. Clinical trial information: NCT02303990.

9000 Background: In the randomized phase 3 CheckMate 9LA trial (NCT03215706), first-line NIVO + IPI combined with 2 cycles of chemo significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) vs chemo alone (4 cycles). Clinical benefit was observed regardless of programmed death ligand 1 (PD-L1) expression level and histology. Here we report data with 2 years’ minimum follow-up from this study. Methods: Adult patients (pts) with stage IV / recurrent NSCLC, ECOG performance status ≤ 1, and no known sensitizing EGFR/ALK alterations were stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous) and were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles; n = 361) or chemo alone (4 cycles; n = 358). Pts with non-squamous NSCLC in the chemo-alone arm could receive pemetrexed maintenance. The primary endpoint was OS. Secondary endpoints included PFS and ORR by blinded independent central review, and efficacy by different PD-L1 levels. Safety was exploratory. Results: At a minimum follow-up of 24.4 months for OS (database lock: Feb 18, 2021), pts treated with NIVO + IPI + chemo continued to derive OS benefit vs chemo, with a median OS of 15.8 months vs 11.0 months, respectively (HR, 0.72 [95% CI, 0.61–0.86]); 2-year OS rates were 38% vs 26%. Median PFS with NIVO + IPI + chemo vs chemo was 6.7 months vs 5.3 months (HR, 0.67 [95% CI, 0.56–0.79]); 8% and 37% of pts who had disease progression received subsequent immunotherapy, respectively. ORR was 38% with NIVO + IPI + chemo vs 25% with chemo. Similar clinical benefit with NIVO + IPI + chemo vs chemo was observed in all randomized pts and across the majority of subgroups, including by PD-L1 expression level (Table) or histology. Any grade and grade 3–4 treatment-related adverse events were reported in 92% and 48% of pts in the NIVO + IPI + chemo arm vs 88% and 38% in the chemo arm, respectively. Conclusion: With 2 years’ minimum follow-up, first-line NIVO + IPI + chemo demonstrated durable survival and benefit versus chemo in pts with advanced NSCLC; no new safety signals were identified. Clinical trial information: NCT03215706. [Table: see text]

9542 Background: Anti-PD-1 antibody monotherapy (PD1) has been commonly used for patients with advanced acral melanoma (AM). However, recent studies have demonstrated the limited clinical efficacy of PD1 in AM compared to non-acral cutaneous melanoma, particularly in nail apparatus melanoma. Although advanced AM patients are strong candidates for first-line anti-PD-1 and anti-CTLA-4 combination therapy (PD1+CTLA4), data on the clinical efficacy of PD1+CTLA4 in AM are lacking. Thus, we aimed to compare the clinical efficacies of PD1+CTLA4 and PD1 in Japanese advanced AM patients. Methods: We retrospectively reviewed the clinical records of advanced AM patients treated with PD1+CTLA4 or PD1 as first-line immunotherapy at 23 Japanese institutions. Clinical response was assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Survival was estimated using Kaplan-Meier analysis. Toxicity was assessed according to CTCAE 4.0. Results: A total of 192 patients (median age, 72 years) with advanced AM (palm and sole melanoma, 135; nail apparatus melanoma, 57) were included in the study. PD1+CTLA4 and PD1 were used as first-line immunotherapy in 39 and 153 patients, respectively. The baseline demographics and characteristics were similar between the PD1+CTLA4 and PD1 groups, except for age (median age 67.3 vs. 73.2; P = 0.005). The objective response rate (ORR) in PD1+CTLA4 was significantly higher than that of the PD1 group (38.5% vs. 16.3%; P = 0.047). The median progression-free survival (PFS) and overall survival (OS) in the PD1+CTLA4 group tended to be longer than those of the PD1 group, but the differences were not significant (median PFS 7.3 months vs. 4.5 months; P = 0.19, median OS 43.6 months vs. 18.2 months; P = 0.19). In the subgroup analysis of the palm and sole melanoma cohorts, no significant differences in ORR, PFS, and OS were observed between the PD1+CTLA4 and PD1 groups (ORR 31% vs. 20.8%; P = 0.67, median PFS 5.3 months vs. 5.9 months; P = 0.87, median OS not reached vs. 22.3 months; P = 0.66). Meanwhile, the nail apparatus melanoma cohort in the PD1+CTLA4 group exhibited significantly higher ORR, and longer PFS and OS than the PD1 group (ORR 60% vs 6.1%; P < 0.001; median PFS 19.6 months vs 3.8 months; P = 0.008, median OS 43.6 months vs 13.5 months; P = 0.049). Due to immune-related adverse events in all cohorts, the treatment cessation rate was higher in the PD1+CTLA4 group than the PD1 group (59% vs. 11.8%). Conclusions: PD1+CTLA4 was clinically more efficacious than PD 1 in advanced AM patients. Notably, advanced nail apparatus melanoma patients were strong candidates for first-line PD1+CTLA4.

This study investigated the antitumor activity and safety of pembrolizumab in patients with recurrent cervical cancer in real-world practice. We conducted a multi-center retrospective study of patients with recurrent or persistent cervical cancer treated with pembrolizumab at sixteen institutions in Korea between January 2016 and March 2020. The primary endpoints were the objective response rate (ORR) and safety. Data were available for 117 patients. The median age was 53 years (range, 28–79). Sixty-four (54.7%) patients had an Eastern Cooperative Oncology Group (ECOG) performance status of ≥2. Forty-nine (41.9%) patients were stage ≥III at diagnosis. Eighty-eight (75.2%) patients had squamous cell carcinoma. The median number of prior chemotherapy lines was two (range, 1–6). During the median follow-up of 4.9 months (range, 0.2–35.3), the ORR was 9.4%, with three complete responses and eight partial responses. The median time to response was 2.8 months (range 1.3–13.1), and the median duration of response (DOR) was not reached. In the population of patients with favorable performance status (ECOG ≤1) (n = 53), the ORR was 18.9%, and the median DOR was 8.9 months (range, 7.3–10.4). Adverse events occurred in 55 (47.0%) patients, including eight (6.8%) patients who experienced grade ≥3 events, and two of them were suspicious treatment-related deaths. Pembrolizumab had modest antitumor activity in patients with recurrent cervical cancer comparable to that found in previously reported clinical trials. However, in patients with favorable performance status, pembrolizumab showed effective antitumor activity. Some safety profiles should be carefully monitored during treatment.

Background: Liposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (5-FU/LV) was effective and well-tolerated in patients with metastatic pancreatic adenocarcinoma (mPAC) that progressed on gemcitabine-based therapy in the global NAPOLI-1 trial. Real-world data may further clarify the outcomes and safety profile of nal-IRI + 5-FU/LV in clinical practice. Methods: This retrospective analysis included patients with mPAC who received nal-IRI + 5-FU/LV following gemcitabine-based therapy under a Managed Access Program in Korea. Results: From January 2017 to April 2018, 86 patients across 10 institutions received nal-IRI + 5-FU/LV (median age, 61 years; 60% male; ECOG performance status, 0–1). A total of 35 (41%) and 51 (59%) patients had received less than two and two or more lines of chemotherapy before inclusion, respectively. At a median follow up of 6.4 months, median overall survival (OS) was 9.4 months (95% confidence interval [CI] 7.4–11.4) and median progression-free survival (PFS) was 3.5 months (95% CI 1.3–5.7). Six-month OS and PFS rates were 65.1% and 37.5%, respectively. Objective response and disease control rates were 10% and 55%, respectively. Most common grade 3–4 toxicities were neutropenia (37.2%), nausea (10.5%), vomiting (9.3%), anorexia (8.1%) and diarrhoea (4.7%). Conclusion: Real-life data for Korean patients indicate that, consistent with NAPOLI-1, nal-IRI + 5-FU/LV is effective and well-tolerated in patients with mPAC that progressed on gemcitabine-based therapy.

14599 Background: We prospectively conducted a phase II trial to test the efficacy and safety of irinotecan, 5-fluorouracil and leucovorin (FOLFIRI) regimens for the first-line treatment of previously untreated patients with recurrent or metastatic advanced CRC. Methods: Thirty-four previously untreated patients with advanced CRC were enrolled in this study from June 2001 to December 2006. Eligible patients had histologically confirmed adenocarcinoma, no prior systemic therapy in palliative setting, ECOG PS = 2, adequate organ function, written informed consent and at least one measurable disease. The patients received either irinotecan 180 mg/m2 on day 1 with a LV bolus of 200 mg/m2 and a FU bolus of 400 mg/m2, and this was followed by a FU continuous infusion of 600 mg/m2 on day 1 and day 2 (the classic FOLFIRI regimen), or they were treated with a LV bolus of 400 mg/m2 and a FU bolus of 400 mg/m2 followed by a FU continuous infusion of 2,400 mg/m2 for 46 hours (the simplified FOLFIRI regimen), and these treatments were repeated every 2 weeks until disease progression. Results: There were 13 females and 21 males with median age of 54 years (range: 41–79). The most common metastatic sites were lung and liver. A total of 262 cycles were administrated with median 6 cycles per patient (range: 1–22). All pts were evaluable for toxicity, and 30 pts for response to the treatment. The objective response rate was 26.4% with 2 complete responses respectively. Sixteen (47%) pts had stable disease and 7 (20.5%) had a progression. The tumor control rate was 73.4%. The median TTP was 5.3 months, and the overall survival was 10.1 months. The prognostic factor for longer TTP and survival was the ECOG performance status (PS). The type of regimens was not affected on response rate, TTP and survival. The chemotherapy was generally well tolerated and the most common grade 3–4 toxicities were neutropenia, diarrhea. The non- hematological toxicities were similar for both treatment groups, with more frequent grade =3 neutropenia being noted for the simplified FOLFIRI regimen. Conclusions: The FOLFIRI regimen was demonstrated to have a moderate antitumor activity with acceptable toxicity profiles, and tend to show more favorable outcome for patients with good ECOG PS. No significant financial relationships to disclose.

4506 Background: Sunitinib (S) is established as a standard first-line therapy for patients (pts) with advanced RCC. However, treatment can be limited by the occurrence of drug-related adverse events (AEs). This Phase II study assessed the efficacy and safety of nintedanib (N) – a potent, triple angiokinase inhibitor of VEGFR-1–3, PDGFR-α/β, and FGFR-1–3, as well as RET and Flt3 – vs S in previously untreated pts with RCC. Methods: Ninety-nine eligible pts (96 of whom were treated) with advanced, unresectable/recurrent clear cell RCC, an ECOG performance status of 0–1, and no prior systemic therapy were randomized 2:1 to receive N 200 mg twice daily (n=64; given in 4-week cycles) or S 50 mg once daily (n=32; 4 weeks on, 2 weeks off schedule). Treatment continued until disease progression or unacceptable drug-related AEs. Primary endpoints were progression-free survival at 9 months (PFS-9) and, in N-treated pts only, QTc interval change (baseline to day 15). Secondary endpoints included PFS, objective response rate (ORR; RECIST 1.1), overall survival (OS), time to progression (TTP), time to treatment failure (TTF), and AEs. Results: Baseline characteristics were balanced between the arms. PFS-9 was not statistically significantly different between N- and S-treated pts (43 vs 45%; p=0.85). There were also no statistically significant differences between N and S with regard to PFS (median: 8.44 vs 8.38 mo; hazard ratio: 1.16; 95% CI: 0.71–1.89; p=0.56), confirmed ORR (18.8 vs 31.3%; p=0.19), OS (median: 20.37 vs 21.22 mo; p=0.63), TTP (median: 8.48 vs 8.54 mo; p=0.52), and TTF (median: 8.41 vs 8.36 mo; p=0.46). Grade ≥3 AEs occurred in 47% of N-treated pts and 56% of S-treated pts. Common AEs (all grades; N vs S) included diarrhea (61 vs 50%), nausea (38 vs 34%), fatigue (both 25%), and vomiting (16 vs 22%). Dermatologic AEs (8 vs 47%) were less frequent with N than S. There was no increase from baseline in QTc >60 ms on days 1 or 15 in N-treated pts, and there was no relationship between N exposure and QT interval change. Conclusions: N demonstrated similar efficacy to S and had a manageable safety profile, including a lower incidence of dermatologic AEs vs S. In addition, N was not associated with QT prolongation. Clinical trial information: NCT01024920.

e20025 Background: Peripheral neuropathy (PN) is a common side effect associated with taxane treatment. In a phase III trial, nab-paclitaxel vs dacarbazine demonstrated a significant improvement in progression-free survival (4.8 vs 2.5 months; P = 0.044) and at the interim survival analysis, a trend toward prolonged overall survival (12.8 vs 10.7 months; P = 0.094) for the treatment of chemotherapy-naive patients with metastatic melanoma. Here we report on the PN profile of nab-paclitaxel in this phase III trial. Methods: Pts (median age, 63 years) with chemotherapy-naive stage IV melanoma (M1c stage, 65%; elevated LDH, 28%) and an ECOG performance status 0-1 were randomized to nab-paclitaxel 150 mg/m2 on days 1, 8, and 15 of a 28-day cycle (n = 264) or dacarbazine 1000 mg/m2on day 1 of each 21-day cycle (n = 265). PN events were defined based on the Standardized MedDRA Query (V 12.1, broad scope). Results: As expected, a higher proportion of pts receiving nab-paclitaxel vs dacarbazine had ≥ 1 treatment-related PN event (68% vs 8%; P < 0.001). Treatment-related grade ≥ 3 PN was more frequent with nab-paclitaxel vs dacarbazine (25% vs 0%; P < 0.001); 2 grade 4 events were reported in the nab-paclitaxel arm. Treatment-related grade ≥ 3 PN was 15% in pts who received up to the median of 3 cycles of nab-paclitaxel. PN led to dose reduction in 13% or discontinuation in 15% of nab-paclitaxel–treated pts. The median time to onset of grade ≥ 3 PN was 101 days (95% CI, 85 - 113). Most early-onset PN events, occurring within the first 3 cycles, were grade 1. Grade ≥ 2 PN events peaked by cycle 4 and subsided by cycle 9. Forty-one of the 64 (64%) pts with a grade ≥ 3 PN event had an improvement of ≥ 1 grade, with a median time to improvement of 28 days (95% CI, 17 - 64), and 33 of 64 (52%) pts had improved to grade 1 or better by a median of 67 days from onset (95% CI, 22- upper limit not estimable); 30 of 64 (47%) pts resumed treatment with nab-paclitaxel. Conclusions: In this phase III trial, grade ≥ 3 PN was the main treatment-related toxicity with nab-paclitaxel as observed in other studies. However, PN was rapidly reversible; a majority of pts had improvement of PN symptoms within 1 month and resumed treatment. Clinical trial information: NCT00864253.

e18546 Background: Small cell lung cancers (SCLC) constitute a mean of 15% of lung cancers and present with advanced disease at time of diagnosis in 60% of cases. Cisplatin plus etoposide schedule is the standard treatment in these patients , whereas the role of maintenance therapy is debated. We assessed the efficacy and safety of oral etoposide maintenance therapy following cisplatin plus etoposide in advanced SCLC. Methods: Demographic features, treatment response, survival rate, and toxicity rate were assessed in our patients who were followed up for advanced SCLC between 2006 and 2012, had a ECOG performance status of 0-1, and were given oral etoposide maintenance therapy (50mg/day, given 14 days of a 21-day cycle, a total of 6 cycles) following 6 courses of cisplatin (75 mg/m2, 1 day) and etoposide (100mg/m2, 3 days). Results: A total of 51 patients were studied, 46 (90.2%) of whom were male; the mean age was 59 (28-78) years at diagnosis. Forty-four (86.2%) patients had partial remission while 7 (13.7%) had complete remission. Nine (17.6%) developed neutropenic fever while grade 3-4 toxicities, neutropenia, anemia, thrombocytopenia, neuropathy, diarrhea, nausea and vomiting were present in 39.2%, 9.8%, 5.9%, 1.9%, 3.9%, 3.9%, and 1.9% respectively. Chemotherapy was postponed in fourteen (27.4%) patients due to toxicity. Six (11.7%) patients taking oral etoposide developed febrile neutropenia and 3 (5.9%) developed grade 3-4 thrombocytopenia. Chemotherapy was postponed in 5 (9.8%) patients due to toxicity while no toxic death was observed. After a median follow-up of 19 months, 32 (62.7%) patients experienced progression of disease and 29 (56.8%) died. Median progression free survival was found 11.6 months (%95 CI; 10.2-12.9 months) and median overall survival was found 15.6 (%95CI; 11.5-19.7 months) months. Conclusions: Our results were similar with the previous literature. Oral etoposide maintenance therapy following cisplatin plus etoposide therapy in advanced SCLC is effective and tolerable. Further randomized studies are needed in this topic.
