4086 Background: Pemigatinib (PEMI), a potent, selective, oral FGFR1-3 inhibitor, has shown efficacy and safety in patients (pts) with CCA and FGFR2 rearrangements/fusions in FIGHT-202 (NCT02924376; objective response rate [ORR], 35.5%; duration of response [DOR], 7.2 months [mo]). Overall survival (OS: 21.1 mo) was not mature in the primary report (Abou-Alfa. Lancet Oncol 2020; cutoff: Mar 22, 2019); herein we report matured efficacy and safety data from FIGHT-202 (cutoff: Apr 7, 2020). Methods: Pts (≥18 y) with known FGF/FGFR alterations and progression after ≥1 prior therapy had FGFR2 rearrangements/fusions (cohort A), other FGF/FGFR alterations (B), or no FGF/FGFR alterations (C). Pts received PEMI 13.5 mg QD (21-d cycle; 2 wks on, 1 wk off) until progression or toxicity. Primary endpoint: independent, centrally confirmed ORR (cohort A); secondary endpoints: ORR (cohorts B, C; cohorts A and B combined); DOR, disease control rate (DCR), progression free survival (PFS), OS, and safety. A post-hoc analysis in cohort A evaluated mOS in responders (pts with complete response [CR] or partial response [PR]) vs non-responders (pts with progressive disease [PD] or stable disease (SD]). Results: At cutoff, 147 pts were enrolled (cohort A, n=108; B, n=20; C, n=17; FGF/FGFR status undetermined, n=2); median follow-up was 30.4 (range, 4.9–38.7) mo and median treatment duration was 5.9 (0.2–36.5) mo. In cohort A, 9.3% of pts remained on therapy at cutoff; in cohorts B and C, all pts had discontinued. Pts discontinued mainly for PD (67.6%, 75%, and 64.7% in cohorts A, B, and C respectively). Independent, centrally confirmed ORR was 37.0%; mOS was 17.5 mo (95% CI, 14.4-22.9) in cohort A (Table 1). mOS for responders (n=40) vs non-responders (n=68) was 30.1 (95% CI, 21.5-NE) mo vs 13.7 (9.6-16.1) mo. Overall, most common all-cause treatment-emergent adverse events (TEAEs) were hyperphosphatemia (58.5%; grade ≥3, 0%), alopecia (49.7%; 0%), diarrhea (46.9%; 3.4%), fatigue (43.5%; 5.4%), nausea (41.5%; 2%), and dysgeusia (40.8%; 0%); 10.2%, 13.6% and 42.2% of pts discontinued, had dose reduction, and treatment interruption due to TEAEs, respectively. Conclusions: These results reinforce the primary data, showing continued, durable responses and sustained tolerability in pts receiving PEMI for CCA harboring FGFR2 rearrangements/fusions. Notably, the matured OS is longer than historical data; OS for responders was more than twice as long vs for non-responders. Clinical trial information: NCT02924376. [Table: see text]

415 Background: Immune checkpoint inhibitors (ICI) have been approved in solid tumors with dMMR. However, only limited data are available for PDAC with dMMR given the rarity of dMMR in PDAC. We evaluated efficacy of ICIs in PDAC with dMMR. Methods: Retrospective clinical and pathologic data were collected for patients (pts) with pancreatic adenocarcinoma from May 2017 to June 2020 at Moffitt cancer center. Results: We identified 10 pts with dMMR PDAC. The median age was 64.5 years (range: 42-86) and 4 pts were male. 4 pts had resectable disease, 3 had locally advanced and 3 had metastatic disease at initial diagnosis. MSH6 deficiency (def) was found in 2 cases, PMS2 def in 2, MLH/PMS2 def in 5, and MSH2/MSH6 in 1. 7 pts were treated with ICIs. 3 pts had locally advanced and 4 had metastatic disease when they started ICIs. 5 received Pembrolizumab (pem), 1 received ipilimumab/ nivolumab (ipi/nivo), and 1 received pem then ipi/nivo after progressive disease (PD) on pem. The median number of prior lines of chemotherapy was 1 (range 0-2). 6 pts were evaluable, and 1 had rapid disease progression after 1 dose of pem. Among 6 evaluable pts, 3 had an objective response (1: complete response and 2: partial response), and 2 had stable disease (SD). Median progression-free survival was 8.2 mo, and median overall survival was not reached with median follow-up (FU) of 6.8 mo. The median duration of response was not reached with a median FU of 22.6 mo. The pt with CR remained disease-free for up to 22 months. The pt whose treatment was switched to ipi/nivo after PD on pem achieved SD > 4mo on ipi/nivo. While on immunotherapy, one patient with ipi/nivo developed immunotherapy associated rash requiring systemic steroids, and another on pem developed hypothyroidism requiring levothyroxine. Conclusions: This series suggest ICIs can provide durable clinical efficacy in pts with dMMR PDAC.

5008 Background: LEN, a multikinase VEGFR inhibitor, plus everolimus is approved for advanced RCC after prior VEGF-targeted therapy. PEMBRO, an anti-PD-1 antibody, plus axitinib is approved as first-line therapy of advanced RCC. We report phase 2 results of the RCC cohort of a phase 1b/2 trial (Study 111/KEYNOTE-146) of LEN + PEMBRO in patients (pts) who progressed after ICI therapy. Methods: We performed a multicenter, open-label study of pts with mccRCC, who previously had disease progression by RECIST (confirmed ≥ 4 weeks later) during or following ICI therapy. Pts had measurable disease by immune-related RECIST, and ≥ 1 prior therapy. Pts received LEN 20 mg orally once daily plus PEMBRO 200 mg IV every 3 weeks until disease progression or toxicity. Tumor assessments were performed every 6 weeks (until week 24), then every 9 weeks. The primary endpoint was objective response rate (ORR) at Week 24 by irRECIST. Results: 104 pts were enrolled. At data cutoff (January 12, 2020), 71 (69%) pts were still on study treatment. Most pts had ≥2 prior anticancer regimens (58%). 91 of 104 pts were evaluable for response at Week 12 (13 pts NE at Week 12); 46 of 91 pts achieved a confirmed partial response for an ORR of 51% (Table). Median progression-free survival (PFS) was 11.7 months and median duration of response (DOR) was 9.9 months. The most common treatment-related adverse events (TRAEs) were fatigue (49%), diarrhea (44%), proteinuria (37%), hypertension (31%), nausea (31%), dysphonia (29%), stomatitis (29%), and arthralgia (27%). There was 1 grade 5 TRAE (upper gastrointestinal hemorrhage). 43% of pts required dose reduction and 12% of pts discontinued treatment due to TRAEs. Response and safety data will be updated to include all pts evaluable at an April 9, 2020 cut-off. Conclusions: LEN + PEMBRO demonstrated promising antitumor activity in pts with mccRCC with disease progression following ICI therapy. No new safety signals were detected. Efficacy outcomes by investigator review per irRECIST. Clinical trial information: NCT02501096 . [Table: see text]

FGFR2 rearrangements resulting in dysregulated signaling are drivers of cholangiocarcinoma (CCA) tumorigenesis, and occur almost exclusively in intrahepatic CCA. Pemigatinib, a selective, potent, oral inhibitor of FGFR1–3, has demonstrated efficacy and safety in a Phase II study of patients with previously treated locally advanced/metastatic CCA harboring FGFR2 fusions/rearrangements. We describe the study design of FIGHT-302, an open-label, randomized, active-controlled, multicenter, global, Phase III study comparing the efficacy and safety of first-line pemigatinib versus gemcitabine plus cisplatin in patients with advanced CCA with FGFR2 rearrangements (NCT03656536). The primary end point is progression-free survival; secondary end points are objective response rate, overall survival, duration of response, disease control rate, safety and quality of life. Clinical Trial Registration: NCT03656536 ( ClinicalTrials.gov )

192 Background: Merkel cell carcinoma (MCC) is a rare, aggressive skin cancer. Avelumab, a human anti–PD-L1 monoclonal antibody, is FDA and EMA approved for the treatment of metastatic MCC (mMCC). Here, we report efficacy and safety data for avelumab in patients (pts) with mMCC at ≥18-mo of follow-up. Methods: Pts with mMCC and progression on prior chemotherapy received avelumab 10 mg/kg IV Q2W. Objective response rate (ORR), duration of response (DOR), and progression-free survival (PFS) were evaluated by independent review committee (RECIST v1.1) with tumor assessment every 6 wks; overall survival (OS) and adverse events (AEs; NCI CTCAE v4.0) were also evaluated. Results: As of Mar 24, 2017, 88 pts were treated and followed for a median of 23.0 mo (range 18.7–32.0). Median treatment duration was 17 wks (range 2–132; mean 35 wks ±37). Treatment was ongoing in 15 pts (17%); 7 pts (8%) voluntarily discontinued with continuing responses (5 complete responses [CR] and 2 partial responses). Other reasons for discontinuation were disease progression (n = 42; 48%), death (n = 10; 11%), AE (n = 8; 9%), or consent withdrawal/other (n = 6; 7%). Confirmed ORR of 33% (95% CI 23.3–43.8; CR in 11.4%) remained unchanged from previous analysis and median DOR has not been reached (range 2.8–24.9 mo; 95% CI 18.0–not estimable). Responses were ongoing in 20/29 pts (69%), including 5 pts with > 2 y of follow-up. PFS curve showed a plateau with identical 12- and 18-mo rates of 29% (95% CI 19–39). Median OS was 12.6 mo (95% CI 7.5-19.0) and the 12- and 18-mo OS rates were 51% (95% CI 40–61) and 40% (95% CI 29–50), respectively. 66 pts (75%) had a treatment-related (TR)AE, most commonly ( > 10%) fatigue (25%), infusion-related reaction (15%; all grade 1/2), nausea (11%), and diarrhea (11%); 8 (9%) had a grade ≥3 TRAE. 17 pts (19%) had an immune-related AE, which was grade ≥3 in 4 pts (4.5%). No treatment-related deaths occurred. Conclusions: Updated results demonstrate continued durable antitumor activity of avelumab in pts with mMCC, beyond that expected with cytotoxic chemotherapy. The median OS exceeding 1 y and manageable safety profile of avelumab signify a clinically meaningful benefit in pts with mMCC. Clinical trial information: NCT02155647.

4522 Background: For patients (pts) with metastatic ESCC, the prognosis is poor. Rh-endostatin (endostar), a potent inhibitor of angiogenesis, has shown clinical activity when combined with chemoradiotherapy in treating locally advanced ESCC. This single-arm phase 2 study was designed to assess the efficacy and safety of endostar combined with paclitaxel and nedaplatin in treating pts with recurrent or metastatic ESCC. Methods: Eligible pts had recurrent or metastatic ESCC and Karnofsky score ≥70. Endostar (30 mg/day, continuous infusion, day 1-14) plus paclitaxel (150 mg/m2, day 4) and nedaplatin (80 mg/m2, day 4) were administered every 3 weeks for 6 cycles followed by maintenance therapy with endostar. Primary endpoint was progression-free survival (PFS). Secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS) and adverse events (AEs). Results: From January 2015 to August 2019, 53 pts were enrolled. 44 (83%) pts were male. The median age was 59 years. 43 (81%) pts had pathology of poor or moderate differentiated ESCC. The middle and lower thirds of the esophagus (81%) were the most common primary tumor sites. 11 (21%) patients had undergone esophagectomy. At the time of treatment, 49 (93%) pts were diagnosed with clinical stage IVB. The most common metastatic sites were lymph node (91%), lung (32%) and liver (26%). 50 pts were assessable for response. No complete response was observed. 21 pts achieved a best response of partial response and 14 pts had stable disease. ORR was 42% and DCR was 70%. The median PFS and OS was 5.1 months (95% CI 3.7-6.6 months) and 13.2 months (95% CI 8.0-18.4 months) respectively. The most common AEs observed during this study were anemia (49.1%), neutropenia (34%), fatigue (28.3%) and anorexia (26.4%). The most common Grade 3/4 AE observed was neutropenia (17%). Conclusions: The combination of endostar plus paclitaxel and nedaplatin is a well tolerated treatment modality with promising activity in previously untreated recurrent or metastatic ESCC. Its efficacy and safety could be further studied in randomized trials. Clinical trial information: NCT02350517 .

8025 Background: Daratumumab (D) is a human CD38-targeting mAb that significantly prolongs progression-free survival (PFS) when added to standard-of-care regimens in patients (pts) with RRMM. We examined updated efficacy and safety data from POLLUX (NCT02076009), a randomized phase 3 study of DRd vs Rd in RRMM. Methods: Pts with ≥1 prior line of therapy (LOT) received Rd (25 mg PO lenalidomide on days 1-21 of each q4w cycle; 40 mg dexamethasone weekly) ± D (16 mg/kg IV qw for cycles 1 and 2, q2w for cycles 3-6, then q4w until disease progression). Pts refractory to lenalidomide were ineligible. Minimal residual disease (MRD) was assessed on bone marrow samples at time of suspected complete response (CR) and at 3 and 6 months post-suspected CR at sensitivities of 10–4, 10–5, and 10–6 via next-generation sequencing (Adaptive Biotechnologies, Seattle, WA). Results: Pts received a median (range) of 1 (1-11) prior LOT. 55% received prior IMiDs (18% lenalidomide). Based on previous median follow-up of 17.3 months, DRd significantly prolonged PFS (median: not reached vs 17.5 months; HR, 0.37; 95% CI, 0.28-0.50; P< 0.0001) and significantly improved overall response rate (ORR; 93% vs 76%, P< 0.0001) vs Rd. DRd induced higher rates of deep responses vs Rd (≥very good partial response [VGPR]: 78% vs 45%; ≥CR: 46% vs 20%; all P< 0.0001) and included MRD negativity, which was > 3-fold higher across all 3 sensitivity thresholds for DRd vs Rd (25% vs 6% at the 10–5 threshold). MRD-negative pts demonstrated longer PFS vs MRD-positive pts. Follow up for overall survival (OS) is ongoing (OS events: 40 [14%] in DRd and 56 [20%] in Rd). No new safety signals were identified with longer follow up. Updated efficacy and safety data based on approximately 25-months follow up will be presented at the meeting. Conclusions: DRd provided significant benefits vs Rd in terms of PFS, ORR, and MRD negativity, and the favorable safety profile of DRd was maintained with longer follow up. These data further validate the use of DRd in RRMM pts who received ≥1 prior therapy. Clinical trial information: NCT02076009.

4524 Background: In the open-label, single-arm, phase 2 CheckMate 275 trial, objective response rate (ORR) for patients (pts) with metastatic urothelial carcinoma (mUC) with nivolumab (NIVO) was 20.4% with minimum follow-up of 21.3 mo. Here, we report updated efficacy and safety data with minimum follow-up of 33.7 mo. Methods: Pts with platinum-resistant locally advanced or metastatic urothelial carcinoma received NIVO 3 mg/kg until disease progression or unacceptable toxicity. The primary endpoint was ORR by blinded independent review committee (BIRC) by RECIST v1.1 (including duration of response [DOR]). Secondary endpoints included progression-free survival (PFS) by BIRC, overall survival (OS), and ORR per investigator. Efficacy was evaluated in all treated pts and by tumor PD-L1 expression. Safety and PFS by investigator were exploratory endpoints. Results: ORR by BIRC was 20.7% (95% CI 16.1–26.1) including 18 (7%) complete responses (CR; with 1 additional CR since the last report; Table). ORR per investigator was similar (24.8%). Median DOR by BIRC was 20.3 mo (95% CI 11.5–31.3). Of 56 pts with best overall response (BOR) of CR or partial response (PR), 59% had a DOR ≥12 mo. Median PFS (mPFS) was 1.9 mo per BIRC (95% CI 1.9–2.3; Table) and 2.0 mo per investigator (95% CI 1.9–2.5). Median OS (mOS) was 8.6 mo (95% CI 6.1–11.3; Table). 12, 24, and 36-mo OS rates were 40%, 30%, and 22%. While efficacy was numerically higher in pts with tumor PD-L1 expression ≥1%, efficacy was observed in all pts (Table). Any-grade treatment-related adverse events occurred in 69% of pts (grade 3–4, 25%), mostly (59%) within the first 3 mo of initiating therapy. Conclusions: With long-term follow-up from CheckMate 275, NIVO continues to provide durable antitumor activity in pts with mUC. No new safety signals were noted. Clinical trial information: NCT02387996. [Table: see text]

4096 Background: Regorafenib (R) has shown promising efficacy in patients (pts) with BTC refractory to standard chemotherapy. Anti-PD1/PD-L1 antibodies have only limited clinical activity. Synergy between R and anti–PD-1/PD-L1 antibodies has been shown in pre-clinical solid tumor models. Methods: This is a single-arm open-label multicentric phase II trial (Bayesian adaptive design) assessing the efficacy and safety of R (160 mg QD 3weeks/4) + avelumab (A) (10 mg/kg every 2 weeks) combination in BTC pts. The primary endpoint was the objective response rate under treatment, based on central review according to RECIST 1.1. Secondary endpoints included: 1-year progression free survival (PFS), 1-year overall survival (OS), and Safety using NCI-CTCAE v5.0. Correlative studies were planned from pts tumor samples obtained at baseline. Results: Between Nov. 2018 and Nov. 2019, 34 BTC pts were enrolled in 4 centers. Median age was 63 (range 36 – 80). Median follow-up was 9.8 months. Median number of previous treatment lines for metastatic or locally advanced disease was: 2 (range 1 – 4). Twenty-nine (85.3%) pts experienced at least 1 dose modification or treatment interruption of R or A due to an adverse event (AE) related to the treatment. The most common grade 3/4 AEs were : Hypertension (17.6%), Fatigue (14.7%), and maculo-papular rash (11.8%). No death was related to the treatment. Among the 29 pts with at least one imaging tumor assessment, 4 (13.8%) achieved a partial response, and 11 (37.9%) demonstrated stable disease including 10 (34.5%) pts with tumor shrinkage. Fourteen pts (48.3%) had progressive disease. The median PFS and OS were 2.5 months (95%CI 1.9 – 5.5) and 11.9 months (95%CI 6.2 – NA) respectively. Baseline tumor samples were available for 27 pts. High IDO and PD-L1 expression at baseline was associated with better outcome. Conclusions: The R+A combination is associated with significant anti-tumor activity with promising survival rates in this heavily pre-treated population. Full Biomarkers analyses will be presented at the meeting. Clinical trial information: NCT03475953.

Purpose The multicohort phase Ib KEYNOTE-028 (NCT02054806) study was designed to evaluate the safety and efficacy of pembrolizumab, an anti–programmed death 1 monoclonal antibody, in patients with programmed death ligand 1 (PD-L1) –positive advanced solid tumors. The results from the advanced endometrial cancer cohort are reported. Patients and Methods Female patients with locally advanced or metastatic PD-L1–positive endometrial cancer who had experienced progression after standard therapy were eligible. Patients received pembrolizumab 10 mg/kg every 2 weeks for up to 24 months or until progression or unacceptable toxicity. Primary efficacy end point was objective response rate by RECIST (version 1.1). Secondary end points included safety, duration of response (DOR), progression-free survival, and overall survival. The data cutoff was February 17, 2016. Results Of 75 patients screened, 36 (48.0%) had PD-L1–positive tumors, and 24 (32.0%) were enrolled. Fifteen (62.5%) of these 24 patients had received at least two previous lines of therapy for advanced disease. Three patients (13.0%) achieved confirmed partial response (95% CI, 2.8% to 33.6%); the median DOR was not reached. Two patients were still receiving treatment and exhibiting continued response at time of data cutoff. Three additional patients (13.0%) achieved stable disease, with a median duration of 24.6 weeks. One patient who achieved partial response had a polymerase E mutation. Thirteen patients (54.2%) experienced treatment-related adverse events (AEs), with fatigue (20.8%), pruritus (16.7%), pyrexia (12.5%), and decreased appetite (12.5%) occurring in ≥ 10% of patients. Grade 3 treatment-related AEs were reported in four patients. No patient experienced a grade 4 AE, and no patient discontinued treatment because of an AE. Conclusion Pembrolizumab demonstrated a favorable safety profile and durable antitumor activity in a subgroup of patients with heavily pretreated advanced PD-L1–positive endometrial cancer.

PURPOSE: To assess the safety and efficacy of vinorelbine in patients with AIDS-related Kaposi’s sarcoma (KS). PATIENTS AND METHODS: From December 1994 to May 1997, within the Italian Cooperative Group on AIDS and Tumors, we enrolled 36 patients with AIDS-related KS who experienced disease progression after one or more regimens of systemic chemotherapy. Patients were treated with vinorelbine 30 mg/m2 every 2 weeks by intravenous bolus. RESULTS: Of 35 assessable patients, three (9%) had a clinical complete response and 12 (34%) had a partial remission, for an overall objective response rate of 43% (95% confidence interval, 26% to 61%). For the 15 patients with objective responses, the median duration of response from the beginning of therapy until the development of progression was 176 days, whereas the median progression-free survival and the median survival durations for 35 assessable patients were 151 days and 216 days, respectively. Vinorelbine also induced responses in patients who had become resistant to regimens that included other vinca alkaloids. Overall, vinorelbine was well tolerated. Toxicity, including neurologic toxicity, was mild and reversible. Neutropenia was the most frequent dose-limiting toxicity. CONCLUSION: Vinorelbine is safe and effective in the treatment of patients with advanced KS who have been previously treated with one or more chemotherapy regimens.
