617 Background: CheckMate 025 demonstrated superior overall survival (OS) in previously treated patients (pts) with aRCC, with improved safety and tolerability in the NIVO arm compared with EVE. The primary analysis was based on 14-months minimum follow-up. Here, we report an updated, final analysis with an extended minimum follow-up of 64 months. Methods: Previously treated pts with predominantly clear cell aRCC were randomized (1:1) to NIVO 3 mg/kg IV every 2 weeks or EVE 10 mg orally once daily until progression or unacceptable toxicity. The primary endpoint was OS. Secondary endpoints included objective response rate (ORR), progression-free survival (PFS), and safety. Confirmed ORR and PFS were per investigator (inv) using RECIST v1.1. Results: Overall, 410 vs 411 pts were randomized to NIVO vs EVE, respectively. OS benefit was maintained and PFS favored NIVO vs EVE with long-term follow-up (HR 0.84 (95% CI 0.72–0.99). (Table) ORR was higher (23% vs 4%) with NIVO vs EVE and median duration of response (DOR) was longer (18.2 vs 14.0 months). Ongoing response was observed in 28% vs 18% of pts with NIVO vs EVE. Most pts received subsequent systemic anticancer therapy: 276 pts in the NIVO arm (67%; most commonly EVE [35%] or axitinib [33%]) and 296 pts in the EVE arm (72%; most commonly axitinib [41%] or NIVO [26%]). No new safety signals or treatment-related deaths emerged with long-term follow-up in either arm. More pts in the EVE arm (37%) experienced a grade 3/4 treatment-related AE compared with pts in the NIVO arm (21%). Conclusions: At >5-years minimum follow-up, response rates and survival remain superior with NIVO vs EVE, and 28% of responses to NIVO are ongoing. Long-term follow-up highlights the efficacy and safety of NIVO monotherapy in pts with aRCC. Clinical trial information: NCT01668784. [Table: see text]

7528 Background: Previously in the COMPLEMENT 1 study, treatment with OFA and CHL in pts with untreated CLL had shown a significant improvement in the progression-free survival (PFS) compared with CHL alone, and was well tolerated. Here, we report the final overall survival (OS) analysis of the 5-year (y) follow-up, updated investigator-assessed PFS and safety from the study. Methods: Untreated pts, not fit for fludarabine-based therapy (due to advanced age or co-morbidities) were randomized 1:1 to OFA+CHL or CHL alone. Pts in OFA+CHL arm received OFA (Cycle 1: 300 mg day (d) 1, 1000 mg d8; subsequent cycles: 1000 mg d1) in addition to CHL (10 mg/m2, d1-7) for 3 to 12 cycles of 28 d each. Pts in CHL arm received CHL only. Results: Overall, 447 pts were randomized to OFA+CHL (n = 221) or CHL (n = 226); 168 (76%) and 164 (73%) pts completed the scheduled treatments, respectively. Baseline characteristics were similar in both arms. The investigator-assessed median PFS was 23.4 months (mos) in the OFA+CHL arm and 14.7 mos in the CHL arm (HR: 0.61 [95% CI 0.49, 0.76], p < 0.001). Median OS could not be estimated for the OFA+CHL arm and was 84.7 mos for the CHL arm (HR: 0.88 [95% CI 0.65, 1.17], p = 0.363). Estimated OS rate (95% CI) at 5 y was 68.5% (61.5%, 74.5%) in the OFA+CHL arm, and 65.7% (58.6%, 71.9%) in the CHL arm. Post-treatment anti-cancer therapy after discontinuation was received by a greater proportion of pts in the CHL (66%) vs. OFA+CHL (56%), and started earlier in the CHL arm (486 d) vs. OFA+CHL (743 d) arm. Overall, 84 (39%) pts in the OFA+CHL, and 99 (44%) pts in the CHL arms died during the study with 5 on-treatment deaths in each group. Grade ≥3 adverse events were seen in 64% and 48% of pts in the OFA+CHL vs. CHL arms, respectively, most common being (≥5% in either arm) neutropenia (26% vs. 15%), thrombocytopenia (5% vs. 10%), pneumonia (9% vs. 5%), and anemia (5% vs. 5%). Conclusions: This 5-y survival follow-up analysis supported the results from primary analysis with an estimated 12% (not significant) and 39% risk reduction in OS and PFS, respectively, in the OFA+CHL arm compared with the CHL arm. No new safety concerns were observed in the OFA+CHL arm. Clinical trial information: NCT00748189.

635 Background: In the phase II CheckMate-142 trial, NIVO + low-dose IPI (1 mg/kg) provided meaningful clinical benefit in previously treated MSI-H/dMMR mCRC pts after a median follow-up of 13.4 mo. Here, we present long-term follow-up (median 25.4 mo) of these pts. Methods: Pts received NIVO 3 mg/kg + low-dose IPI Q3W (4 doses) followed by NIVO 3 mg/kg Q2W until disease progression. Primary endpoint was investigator (INV)-assessed objective response rate (ORR; RECIST v1.1). Results: Of 119 treated pts, 76% had ≥ 2 prior lines of therapy. ORR and disease control rates (DCR) were 58 and 81%, respectively (Table). Complete response (CR) rate increased with long-term follow-up from 3 (13.4 mo) to 6% (25.4 mo). Median duration of response (DOR) was not reached, with 68% of responses ongoing at data cutoff. At 24 mo, progression-free survival (PFS) and overall survival (OS) rates were 60 and 74%, respectively; OS rates were 96, 56, and 29% in pts with CR or partial response (PR), stable disease (SD), and progressive disease (PD), respectively. Grade 3–4 treatment-related adverse events (TRAEs) occurred in 31% of pts; 10% (grade 3–4) and 13% (any grade) of pts had TRAEs leading to discontinuation. Conclusions: Long-term follow-up with NIVO + low-dose IPI provides durable clinical benefit with deepening of response and a manageable safety profile with no new safety signals, demonstrating long-term benefit of NIVO + low-dose IPI for previously treated pts with MSI-H/dMMR mCRC. Clinical trial information: NCT02060188. [Table: see text]

269 Background: NIVO 1 mg/kg + IPI 3 mg/kg Q3W (4 doses) followed by NIVO 240 mg Q2W is approved in the US for sorafenib-treated pts with aHCC based on initial results from CheckMate 040 (NCT01658878), which reported objective response rate (ORR) of 32% and median overall survival (mOS) of 22.8 months (mo).1 We present 44-mo long-term follow-up results from the CheckMate 040 NIVO+IPI cohort. Methods: Pts were randomized to 3 arms: [A] NIVO 1 mg/kg + IPI 3 mg/kg Q3W (4 doses) or [B] NIVO 3 mg/kg + IPI 1 mg/kg Q3W (4 doses), each followed by NIVO 240 mg Q2W, or [C] NIVO 3 mg/kg Q2W + IPI 1 mg/kg Q6W. Treatment continued until intolerable toxicity or disease progression. Safety and tolerability, ORR (blinded independent central review per RECIST v1.1), duration of response (DOR), disease control rate (DCR), and OS were assessed. Data cutoff was May 26, 2020. Results: 148 pts were randomized. Minimum follow-up was 44 mo. mOS remained at 22.2 mo in arm A, 12.5 mo in arm B, and 12.7 mo in arm C; 36-mo OS rates were 42%, 26%, and 30%, respectively. Durable responses were achieved across treatment arms, with DOR approaching 4 years in some cases. DCR was higher in arm A than arms B and C. In all arms, responses were observed regardless of baseline programmed death ligand 1 expression ( < 1% or ≥ 1%) or baseline alpha-fetoprotein level ( < 400 µg/L or ≥ 400 µg/L). Pts with hepatitis B or C virus (HBV or HCV) etiology had higher ORR than uninfected pts in arms B (29% vs 43% vs 9%) and C (31% vs 42% vs 0%). ORR was independent of etiology in arm A (HBV, 32%; HCV, 29%; uninfected, 31%). Additional efficacy data are in the table. There were no additional discontinuations due to treatment-related adverse events or immune-mediated adverse events (IMAEs) since the primary analysis. IMAEs were reported more frequently in arm A than arms B and C; the most common were rash, hepatitis, and adrenal insufficiency. Most IMAEs were reversible and resolved when treated using established algorithms. Conclusions: At a minimum follow-up of 44 mo, second-line NIVO1+IPI3 continued to demonstrate clinically meaningful responses and long-term survival benefit in aHCC. The safety profile was manageable and no new safety signals were identified with longer follow-up. Clinical trial information: NCT01658878. [Table: see text]

<b>Purpose:</b> Patients with advanced endometrial carcinoma have limited treatment options. We report final primary efficacy analysis results for a patient cohort with advanced endometrial carcinoma receiving lenvatinib plus pembrolizumab in an ongoing phase Ib/II study of selected solid tumors. <b>Methods:</b> Patients took lenvatinib 20 mg once daily orally plus pembrolizumab 200 mg intravenously once every 3 weeks, in 3-week cycles. The primary end point was objective response rate (ORR) at 24 weeks (ORRWk24); secondary efficacy end points included duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Tumor assessments were evaluated by investigators per immune-related RECIST. <b>Results:</b> At data cutoff, 108 patients with previously treated endometrial carcinoma were enrolled, with a median follow-up of 18.7 months. The ORRWk24 was 38.0% (95% CI, 28.8% to 47.8%). Among subgroups, the ORRWk24 (95% CI) was 63.6% (30.8% to 89.1%) in patients with microsatellite instability (MSI)-high tumors (n = 11) and 36.2% (26.5% to 46.7%) in patients with microsatellite-stable tumors (n = 94). For previously treated patients, regardless of tumor MSI status, the median DOR was 21.2 months (95% CI, 7.6 months to not estimable), median PFS was 7.4 months (95% CI, 5.3 to 8.7 months), and median OS was 16.7 months (15.0 months to not estimable). Grade 3 or 4 treatment-related adverse events occurred in 83/124 (66.9%) patients. <b>Conclusion:</b> Lenvatinib plus pembrolizumab showed promising antitumor activity in patients with advanced endometrial carcinoma who have experienced disease progression after prior systemic therapy, regardless of tumor MSI status. The combination therapy had a manageable toxicity profile. <b>Trial registration:</b> ClinicalTrials.gov NCT02501096.

8050 Background: Concurrent chemoradiotherapy has been regarded as one of the standard management for localized nasal NKTCL. However, its long-term efficacy and toxicity is not known. Methods: The JCOG0211 trial is a phase I/II study of concurrent chemoradiotherapy consisting of radiotherapy (RT) of 50 Gy and 3 cycles of DeVIC (carboplatin, etoposide, ifosfamide, dexamethasone) for newly diagnosed, localized nasal NKTCL (JCO 2009). Patients (Pts) with newly diagnosed, localized diseases (IE & contiguous IIE with cervical node involvement) who were 20-69 yrs of age with PS 0-2 were eligible. 3-D conformal RT planning with a wide margin (+ 2 cm to the gross tumor, the entire nasal cavity and the nasopharynx) and a 2-step cone down were required. 33 pts were enrolled in the study, 27 of whom were treated with RT and a 2/3-dose of DeVIC, which was selected as the recommended phase II dose in the preceding phase I portion of the trial. All pts completed RT without any protocol violations. Long-term follow-up results on overall survival (OS), progression-free survival (PFS) and toxicity were evaluated. Results: The median follow-up was 69 months (range, 62-96). The pt (N=33) characteristics were as follows: median age 54 yrs (range, 21-68); stage IIE 33%; B symptom (+) 36%; elevated serum LDH 21%. %5-yr OS and PFS were 73% (95%CI, 54-85%) and 67% (95%CI, 48-80%), respectively. 11 pts (33%) experienced disease recurrence. Two achieved a 2nd CR by salvage chemotherapies followed by allogeneic stem cell transplantation, and the remaining 9 pts died of disease. There was no observed death and disease progression after 34 and 31 months, respectively. One pt experienced Grade 3 irregular menstruation for 3 years. No other Grade 3 or 4 late non-RT-associated adverse events (AEs) were observed. One pt received plastic surgery due to Grade 4 RT dermatitis. No other Grade 3 or greater RT-associated late AEs were encountered. Conclusions: Both survival benefit and disease control from concurrent chemoradiotherapy with RT and DeVIC are maintained during a 5-yr follow-up, indicating the excellent efficacy of this approach as a first-line therapy for localized nasal NKTCL. Long-term toxicity is acceptable.

9037 Background: Therapies for aBCC, which includes metastatic (m) and locally advanced (la) BCC, are limited. Abnormal Hedgehog pathway signaling is a key driver in BCC pathogenesis. Primary analysis of the pivotal ERIVANCE BCC trial of vismodegib, an oral hedgehog pathway inhibitor (HPI), demonstrated an objective response rate (ORR) of 30% and 43%, in mBCC and laBCC patients, respectively, with a median duration of response (DOR) of 7.6 months. We present safety and investigator (INV) assessed efficacy results 18 months (29 May 2012) after primary analysis (26 Nov 2010). Methods: Multicenter, international, nonrandomized study in patients (N=104) with radiographically measurable mBCC or laBCC (surgery inappropriate due to multiple recurrence, or substantial morbidity or deformity anticipated) receiving 150 mg oral vismodegib daily until disease progression or intolerable toxicity. Key secondary endpoints included INV-assessed ORR, progression-free survival (PFS), DOR, overall survival (OS), and safety. Results: At data cutoff, 21 patients continued to undergo protocol-specified assessments and 56 patients were in survival follow-up. The median dose intensity was comparable with primary analysis. ORR was 48.5%, mBCC; 60.3%, laBCC, comparable with primary analysis. However, median DOR improved (mBCC=14.7; laBCC=20.3 months). The median OS for mBCC was 30.9 months but not estimable in laBCC. Adverse events remained consistent, with muscle spasm, alopecia, dysgeusia, weight decrease, and fatigue most frequently reported. Eleven more deaths were reported in the update period after primary analysis; these occurred in survival follow-up and were not drug-related. Conclusions: Vismodegib is the first FDA-approved HPI; thus, long-term efficacy and safety data are particularly relevant. 18-month update data confirmed prolonged responses and consistent safety in vismodegib-treated aBCC patients. Clinical trial information: NCT00833417.

9055 Background: LungMAP is a National Clinical Trials Network umbrella trial for previously-treated SqNSCLC. S1400D is a phase II biomarker-driven therapeutic sub-study evaluating the FGFR inhibitor AZD4547 in patients (pts) with FGFR positive chemo-refractory SqNSCLC. Methods: Eligible pts had tumor FGFR alteration and/or mutation by next generation sequencing (Foundation Medicine), measurable disease, Zubrod PS 0-2, progression after 1 line of systemic therapy, and adequate end organ function. Receipt of prior immunotherapy was allowed. Eligible pts received AZD4547 80 mg bid orally. Primary endpoint was overall response rate (ORR) by RECIST; secondary endpoints included progression-free survival (PFS) and duration of response (DoR). Originally designed as a randomized trial of AZD4547 versus docetaxel, it was redesigned to be a single arm AZD4547 trial with the emergence of immunotherapy as standard 2ndline therapy. Forty pts were required to rule out an ORR of < = 15% if the true ORR was > 35% (90% power, alpha 0.05). Results: 93 pts (13% of pts screened on S1400) were assigned to S1400D; 43 were enrolled with 28 receiving AZD4547. Pt characteristics: median age 66.3 y (49-88), female (n = 8, 29%), & Caucasian (n = 25; 89%). Biomarker profile: FGFR1 amplification (n = 38; 86%); FGFR3 S249C (n = 4; 9%); FGFR3 amplification (n = 3; 7%); and FGFR3 fusion (n = 2; 5%). Nine pts (26%) had more than one biomarker alteration. The study was closed at interim analysis for futility in October 2016. Treatment related Grade 3 AEs were seen in 5 pts (dyspnea, fatigue, hyponatremia, lung infection & retinopathy); 1 pt had Grade 4 sepsis. There were no Grade 5 AEs. Median follow up among alive pts was 4.3 months (mos). Of 25 response evaluable pts, one with FGFR3 S249C had unconfirmed PR (4%, 95% CI 1-20%) with DoR of 1.5 mos. Median PFS was 2.7 mos (95% CI 1.4 - 4.3 mos). Conclusions: This is the first Phase II trial to evaluate AZD4547 as a targeted approach in pts with previously treated FGFR-altered SqNSCLC. AZD4547 had an acceptable safety profile but minimal activity in this biomarker-enriched cohort. Evaluation of other targeted agents in LUNG-MAP is currently ongoing. Clinical trial information: NCT02965378.

4040 Background: In the phase 2 CheckMate 142 trial, NIVO + low-dose IPI had robust, durable clinical benefit and was well tolerated as 1L therapy for MSI-H/dMMR mCRC (median follow-up 13.8 months [mo; range, 9–19]; Lenz et al. Ann Oncol 2018;29:LBA18). Longer follow-up is presented here. Methods: Patients (pts) with MSI-H/dMMR mCRC and no prior treatment for metastatic disease received NIVO 3 mg/kg Q2W + low-dose IPI 1 mg/kg Q6W until disease progression or discontinuation. The primary endpoint was investigator-assessed (INV) objective response rate (ORR) per RECIST v1.1. Results: In 45 pts with median follow-up of 29.0 mo, ORR (95% CI) increased to 69% (53–82) (Table) from 60% (44.3–74.3); complete response (CR) rate increased to 13% from 7%. The concordance rate of INV and blinded independent central review was 89%. Median duration of response (DOR) was not reached (Table). Median progression-free survival (PFS) and overall survival (OS) were not reached, and 24-mo rates were 74% and 79%, respectively (Table). Nineteen pts discontinued study treatment without subsequent therapy. An analysis of tumor response post discontinuation will be presented. Ten (22%) pts had grade 3–4 treatment-related adverse events (TRAEs); 3 (7%) had grade 3–4 TRAEs leading to discontinuation. Conclusions: NIVO + low-dose IPI continued to show robust, durable clinical benefit with a deepening of response, and was well tolerated with no new safety signals identified with longer follow-up. NIVO + low-dose IPI may represent a new 1L therapy option for pts with MSI-H/dMMR mCRC. Clinical trial information: NTC02060188 . [Table: see text]

191 Background: Avelumab is a human anti–PD-L1 IgG1 monoclonal antibody that is approved for the treatment of metastatic Merkel cell carcinoma (US and EU) and advanced urothelial carcinoma progressed on platinum therapy (US). Here, we report phase 1b data for avelumab in a cohort of patients (pts) with previously treated metastatic melanoma. Methods: Pts with unresectable stage IIIC or IV melanoma progressed after ≥1 line of therapy for metastatic disease received avelumab 10 mg/kg IV Q2W until progression, unacceptable toxicity, or withdrawal. Endpoints included objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse events (AEs; NCI CTCAE v4.0). Results: As of Dec 31, 2016, 51 pts were treated and followed for a median of 24.2 mo (range 16.1–31.5). Median age was 64 y (range 31–84). Site of primary tumor was cutaneous (n = 28, 54.9%), ocular (n = 16, 31.4%), mucosal (n = 2, 3.9%), or unknown (n = 5, 9.8%). Pts had received a median of 2 prior lines of therapy for advanced disease (range 0–4), including ipilimumab (n = 26, 51.0%). Confirmed ORR was 21.6% (95% CI 11.3–35.3), with complete response in 7.8% and partial response in 13.7%. In pts with cutaneous melanoma, ORR was 28.6% (95% CI 13.2–48.7). There were no objective responses in pts with ocular melanoma; however, 7 pts (43.8%) had stable disease. In pts with ≤1 (n = 25), 2 (n = 17), or ≥3 (n = 9) prior lines, ORR was 36.0% (95% CI 18.0–57.5), 11.8% (95% CI 1.5–36.4), and 0% (95% CI 0–33.6), respectively. Antitumor activity by PD-L1 status will be presented. Median duration of response was not estimable (NE) (95% CI 2.6 mo–NE). Median PFS was 3.1 mo (95% CI 1.4–6.3) and the 6-mo PFS rate was 39.2% (95% CI 25.2–52.9). Median OS was 18.5 mo (95% CI 9.3–NE) and the 12-mo OS rate was 62.3% (95% CI 46.9–74.4). 39 pts (76.5%) had a treatment-related (TR)AE, most commonly infusion-related reaction (25.5%), fatigue (17.6%), and chills (11.8%). 4 pts (7.8%) had a grade ≥3 TRAE. 5 pts (9.8%) had an immune-related AE; all were grade 1/2. No treatment-related deaths occurred. Conclusions: Avelumab showed durable responses, promising survival outcomes, and an acceptable safety profile in pts with previously treated metastatic melanoma. Clinical trial information: NCT01772004.

Mature overall survival (OS) results from the LUME-Meso study of nintedanib (N) + pemetrexed/cisplatin (PEM/CIS) vs placebo (P) + PEM/CIS in chemo-naïve patients (pts) with malignant pleural mesothelioma (MPM).

8506 Background: LUME-Meso is a Phase (Ph) II/III, double-blind, randomized study. N targets MPM by inhibiting VEGFR 1–3, PDGFR α/β, FGFR 1–3, Src and Abl kinases. Primary analysis of the Ph II data demonstrated improved progression-free survival (PFS; hazard ratio [HR]=0.56; 95% confidence interval [CI] 0.34–0.91; p=0.017). Mature Ph 2 OS and updated PFS results are reported here. Methods: Pts with unresectable MPM (ECOG PS 0–1) were stratified by histology (epithelioid/biphasic) and randomized 1:1 to receive ≤6 cycles PEM (500 mg/m2)/CIS (75 mg/m2) Day 1 + N or P (200 mg bid, Days 2–21), followed by N or P monotherapy until progression or toxicity. The primary endpoint was PFS. The primary OS analysis and updated PFS analysis were performed as predefined. Results: 87 pts were randomly assigned (N=44, P=43). OS benefit favored N over P treatment (HR=0.77; 95% CI 0.46–1.29; p=0.319; 62 [71%] OS events) and was greatest in epithelioid pts (HR=0.70; 95% CI 0.40–1.21; p=0.197) with a median (m) OS gain of 5.4 months (mOS [95% CI]: 20.6 [16.2–28.8] N vs 15.2 [12.2–23.6] P). Updated PFS results (HR=0.54; 95% CI 0.33–0.87; p=0.010) also showed greatest benefit for epithelioid pts (HR=0.49; 95% CI 0.30–0.82; p=0.006) with a mPFS gain of 4.0 months (mPFS [95% CI]: 9.7 [7.2–12.4] N vs 5.7 [5.5–7.0] P). Improved forced vital capacity, objective response rates and duration of response were also observed with N treatment. Drug-related adverse events (AEs) in N- vs P-treated pts were 97.7% vs 97.6%. Grade ≥3 AEs of note included neutropenia (27.3% vs 4.9%), ALT (11.4% vs 0) and GGT (6.8% vs 0) elevations, and diarrhea (6.8% vs 0). AEs led to trial discontinuation in only 3 (6.8%) N vs 7 (17.1%) P pts. Conclusions: Mature Ph II OS data show that adding N to standard 1st-line treatment gives a strong signal towards improved OS. Updated PFS confirmed the primary analysis; AEs were manageable. The greatest clinical benefit was observed in pts with epithelioid histology. Median survival of 20.6 months in epithelioid pts treated with N is unprecedented in advanced MPM trials. Ph III is actively recruiting in this pt population. Clinical trial information: NCT01907100.
