e20502 Background: The CNS is often a site of first disease progression in CRZ-treated ALK+ NSCLC. The ALTA trial is assessing BRG, an investigational next-generation ALK inhibitor, in pts with CRZ-refractory advanced ALK+ NSCLC, including pts with baseline brain metastases. Methods: In ALTA (NCT02094573), pts were stratified by presence of baseline brain metastases and best response to prior CRZ and randomized 1:1 to receive BRG at 90 mg qd (arm A) or 180 mg qd with a 7-d lead-in at 90 mg (arm B). Here, we show data for pts with baseline brain metastases. An independent review committee (IRC) assessed intracranial efficacy. Results: Of 222 pts (112 in arm A; 110 in arm B), 80 (71%)/74 (67%) in A/B had baseline brain metastases per investigators, with median age 49/55 y; 74%/76% had received chemotherapy. As of May 31, 2016, 51%/59% of these pts continued to receive BRG in A/B; median follow-up was 9.6/11.4 mo. Intracranial efficacy is shown in the table. Among these pts, most common treatment-emergent adverse events were: nausea 35%/46% (A/B), headache 30%/31%, vomiting 29%/31%, diarrhea 21%/38%, cough 25%/32%; grade ≥3: increased blood CPK 1%/12%, hypertension 4%/7%, increased lipase 4%/3%. Conclusions: BRG yielded substantial intracranial responses with robust iPFS and acceptable safety in ALK+ NSCLC pts with baseline brain metastases in ALTA. 180 mg (with lead-in) showed consistently improved intracranial efficacy compared with 90 mg.

609 Background: N+I demonstrated superior OS and ORR v S in intention-to-treat (ITT) and intermediate/poor-risk (IP) pts with aRCC in CheckMate 214. Here, we report OS, response outcomes per independent radiology review committee (IRRC), and safety with extended min follow-up of 42 mo. Methods: Pts with clear cell aRCC were randomized 1:1 to N 3 mg/kg + I 1 mg/kg Q3W×4 and then N 3 mg/kg Q2W, or S 50 mg daily for 4 wk on, 2 wk off. Endpoints were OS, ORR, and PFS per IRRC using RECIST v1.1 in IP (primary), ITT (secondary), and favorable pts (FAV; exploratory). Results: OS remained superior in ITT (HR 0.72) and IP (HR 0.66) pts with N+I v S (Table). ORR per IRRC was higher and more responses were ongoing with N+I v S (68% v 53% [ITT] and 68% v 52% [IP]). More pts achieved complete response (CR) with N+I and these were ongoing in 86% [ITT] and 84% [IP] of pts. The PFS probability with N+I stabilized after 24 mo at ~35% in ITT and IP pts, whereas probabilities declined over time with S. Among FAV pts, while ORR was 29% with N+I v 54% with S, more pts achieved CR (13% v 6%), and more responses were ongoing (69% v 54%) with N+I v S; 94% of CRs in FAV pts were ongoing with N+I. OS benefits were similar in both arms and PFS probabilities are stabilizing with N+I and declining with S in FAV pts. The incidence of any and grade 3–4 treatment-related AEs was consistent with previous reports and no new drug-related deaths occurred in either arm. Response outcomes per investigator will also be reported. Conclusions: Superior OS and ORR with N+I v S was maintained in ITT and IP pts. More pts treated with N+I experienced CR compared with S, responses and CRs were durable, and PFS probabilities stabilized with N+I after extended follow-up. No new safety signals emerged.

4510 Background: The HCRN GU16-260 trial reported on the efficacy and toxicity of nivo monotherapy in treatment naïve clear cell RCC (Cohort A) and the efficacy of nivo/ipi salvage therapy in pts with tumors resistant to initial nivo monotherapy (Atkins JCO 2020.38.15_suppl.5006). Limited information is available on the effects of such an approach in pts with advanced nccRCC. Methods: Eligible pts with treatment-naïve nccRCC received nivo 240mg IV q2 wk x 6 doses followed by 360mg IV q3 wk x 4 doses followed by 480 mg q4 wk until progressive disease (PD), toxicity, or completion of 96 wks of treatment (Part A). Pts with PD prior to or stable disease (SD) at 48 wks (pSD) were potentially eligible to receive salvage nivo (3mg/kg) /ipi (1 mg/kg) q3 wk x 4 doses followed by q4 wk nivo maintenance for up to 48 wks (Part B). All pts were required to submit tissue from a metastatic lesion obtained within 12 months (mo) prior to study entry and prior to enrolling on Part B for correlative studies. Results: 35 pts with nccRCC were enrolled between 5/2017 and 12/2019 at 12 participating HCRN sites. Median age 63 (range 35-84 years); 89% male. IMDC favorable 8 (23%), intermediate 18 (51%) and poor risk 9 (26%). Of the 35 pts 19 (54%) had papillary, 6 (17%) chromophobe and 10 (29%) unclassified histology. RECIST defined ORR was 5 of 35 (14.3%) [CR 2 (5.7%), PR 3 (8.6%)], SD 16 (45.7%), PD 14 (40.0%). Immune-related ORR was 8 of 35 (22.9%). RECIST ORR by histology was: papillary - 1/19 (5%); chromophobe - 1/6 (17%); unclassified - 3/10 (30%). 9 pts (26%) had tumors with sarcomatoid features with 3 (33%) (2 unclassified, 1 papillary) responding. Median PFS was 4.0 (2.7, 4.3) mo. 21 pts remain alive. None of the responders have progressed or died. 28 pts (25 PD, 3 pSD) were potentially eligible for salvage nivo/ipi (Part B), but 12 did not enroll due to symptomatic PD (2), grade 3-4 toxicity on nivo (3), or other including no biopsy tissue (7). In the 16 Part B pts, best response to nivo/ipi was: PR (1, 6%) – (unclassified/non-sarcomatoid); SD (7, 44%); PD (8, 50%). Grade 3 Treatment-related adverse events (TrAEs) were seen in 7/35 (20%) on nivo. Grade 3-5 TrAEs were seen in 7/16 (44%) on nivo/ipi with 1 pt experiencing sudden death. Correlative studies including PD-L1 status, WES and RNAseq are pending. Conclusions: Nivo monotherapy has limited activity in treatment naïve nccRCC with most responses (4 of 5) seen in pts with sarcomatoid and/or unclassified tumors. Toxicity is consistent with prior nivo studies. Salvage treatment with nivo/ipi was provided in 16 of 28 (57%) pts with PD/pSD on nivo monotherapy, with 1 response observed. Clinical trial information: NCT03117309.

11054 Background: Advanced SyS are rare tumors with limited curative options. FZD10 is highly expressed in SyS but not in normal adult tissue. OTSA101 is a MAb targeting FZD10, labelled with a radioisotope. Methods: We conducted a phase I, FIH study including adult pts with advanced, refractory SyS. In part 1, pts received OTSA101 labelled with In111 used as radiotracer to assess biodistribution and tumor uptake. In part 2, pts with significant tumor uptake were randomized to receive OTSA101 labelled with 370MBq of Y90 (Arm A) or 1110MBq Y90 (Arm B). Primary endpoints were occurrence of unacceptable biodistribution /lack of tumor uptake in part 1 and occurrence of related adverse events (AEs) Grade ≥ 3 during the first 8 weeks following injection of Y90OTSA101 in part 2. Responses were assessed per RECIST 1.1. Results: From January 2012 to June 2015, 20 pts (10 females, median age 43, range 21-67) with advanced SyS were enrolled. Ten pts (50%) had sufficient tumor uptake to proceed to part 2 and 8 were randomized (Arm A: 3 and Arm B: 5). Two pts were not randomized due to worsening PS. During part 2, the most common Grade ≥ 3 AEs were haematological, including reversible lymphopenia, thrombocytopenia and neutropenia, and were more common in Arm B. One pt with SD after 12 weeks received a 2nd injection of 90Y-OTSA101, but experienced fatal hemoptysis. No objective response was observed. Best response was SD in 5/8 pts lasting up to 21 weeks for 1 pt. Conclusions: This FIH shows that radioimmunotherapy targeting FZD10 is feasible and safe in SyS pts. Tumor uptake was heterogeneous but sufficient to select 50% of pts for 90Y-OTSA101 treatment. Due to limited sample size, further clinical investigations are needed to assess the therapeutic activity of 90Y-OTSA101 with a recommended dose of 1110MBq of 90Y.

9104 Background: We present findings of a randomized phase I/II trial studying PD-1 blockade with and without radiotherapy to lung lesions in patients with metastatic NSCLC. Methods: Patients with metastatic NSCLC were randomized to receive pembrolizumab with or without lung-directed radiotherapy (RT). RT referred to stereotactic body radiation therapy (SBRT, 50 Gy in 4 fractions or 70 Gy in 10 fractions) or traditional fractionation (45 Gy in 15 fractions). Pembrolizumab (200mg IV) was started on day 1 and given every 3 weeks for up to sixteen cycles. The primary endpoint was out-of-field response rate (RR), which refers to complete (CR) or partial response (PR) per irRC criteria. Results: Of 124 enrolled patients, 103 received treatment, 5 withdrew consent, 15 screen failures, and 1 was not financially cleared. Twenty-one patients completed 16 cycles of pembrolizumab; 16 patients received SBRT and 20 received traditional RT. Seven patients received salvage RT after progression on pembrolizumab alone and 15 patients received RT six months before starting the trial. In the combined-modality arm, there were 2 grade 4 toxicities and 9 grade 3 toxicities related to treatment. In the pembrolizumab arm, there were zero grade 4 toxicities and five grade 3 toxicities. At the present time, 72 patients were evaluable for response, 36 in both arms; median follow-up was 15.4 months (range: 1.4-125.2 months). RR for out-of-field lesions was 22% and 25% for the pembrolizumab + RT vs pembrolizumab respectively (p = 1.00); median PFS was 10.9 months (95% CI, 8.1-15.3 months) and 8.4 months (95% CI, 3.9-17.1 months) respectively (p = 0.83). When comparing the SBRT vs traditional fractionation sub-cohorts, non-irradiated RR was 38% and 10% respectively (p = 0.10); median PFS was 21.1 and 6.8 months respectively (p = 0.03). Within the pembrolizumab arm, comparing patients who received prior RT vs those that did not, RR was 33% and 19% respectively (p = 0.26). Conclusions: RT, while safe, did not increase the out-of-field response rate in NSCLC patients treated with pembrolizumab. Exploratory analysis suggests responses may be enhanced by SBRT, but not traditional fractionation, which warrants further investigation. Clinical trial information: NCT02444741.

9026 Background: We report an analysis of BRG vs CRZ in Asian vs non-Asian pts with ALK inhibitor–naive, ALK+ NSCLC from ALTA-1L (NCT02737501). Methods: Pts were randomized 1:1 to BRG 180 mg QD (7-day lead-in at 90 mg) or CRZ 250 mg BID. Primary endpoint: blinded independent review committee (BIRC)-assessed PFS (RECIST v1.1). Secondary efficacy endpoints: BIRC-assessed ORR, intracranial (i) ORR, and iPFS. Results: 275 pts were randomized; 108 Asian (BRG/CRZ, n = 59/49), 167 non-Asian (n = 78/89); median age: Asian, 55/56 y; non-Asian, 60/60 y. 32/24% of Asians vs 22/28% of non-Asians received prior chemotherapy for advanced disease; 36/33% vs 24/28% had baseline CNS metastases. As of 19 Feb 2018, median follow-up was 10.1/10.0 mo (BRG/CRZ) in Asians vs 11.0/9.0 mo in non-Asians, with 12 vs 20 PFS events in Asians and 24 vs 43 in non-Asians. In Asians, median BIRC-assessed PFS (mo) was not reached (NR; 95% CI 11.2–NR) with BRG vs 11.1 (9.2–NR) with CRZ (HR 0.41 [95% CI 0.20–0.86]; log-rank P= 0.0261); in non-Asians, BRG PFS was NR (NR) vs 9.4 (7.3–NR) with CRZ (HR 0.54 [0.33–0.90]; log-rank P= 0.0132) (Table). AE profile of each drug was similar in Asians vs non-Asians. Most common any-grade AEs (≥25%) in Asians in BRG arm: diarrhea; elevated blood CPK, ALT, and AST. Discontinuation due to AE (BRG/CRZ): 8.5/6.3% in Asian pts; 14.3/10.1% in non-Asian pts. Conclusions: BRG showed comparable improvement in PFS vs CRZ both in Asians and non-Asians in ALK inhibitor–naive ALK+ NSCLC. Clinical trial information: NCT02737501. [Table: see text]

5005 Background: Nivo + Ipi is an established first-line treatment (tx) for advanced RCC. We hypothesized that the addition of CTLA-4 blockade may not be required for all patients (pts). Furthermore, the optimal duration of Nivo maintenance in responding pts is unknown. In this phase II response-adaptive trial, we investigate the sequential addition of 2 doses of Ipi to induce response in Nivo non-responders (NR) and duration of Nivo in responding pts (NCT03203473). Methods: We enrolled pts with advanced RCC with no prior checkpoint inhibitor exposure. All pts received Nivo alone with subsequent arm allocation based on RECISTv1.1 response within 6 months (mos) of tx. Pts with a confirmed partial response (PR) or complete response (CR) within 6 months (mos) discontinued Nivo and were observed (Arm A). Arm A pts reinitiated Nivo if they developed progressive disease (PD); Ipi was added to Nivo if PD persisted or recurred. Pts with stable disease (SD) or PD after no more than 6 mos of Nivo alone received 2 doses of Ipi (Arm B). The primary endpoints were the proportion with PR/CR at 1-year (yr) after Nivo discontinuation (Arm A) and proportion of Nivo NR who convert to PR/CR after adding Ipi (Arm B). Results: 83 pts initiated tx of whom 99% had ECOG 0-1, 96% clear cell RCC, 51% tx-naïve, and 69% IMDC intermediate/poor risk. Median follow-up was 17.0 mos. 15 pts were not allocated to an arm [7 withdrew for PD, 7 withdrew for toxicity, 1 still on tx with unconfirmed PR (uPR)]. At 6 mos, induction Nivo resulted in a confirmed PR in 11% of pts (n=9/83): 12% (n=5/42) tx-naïve, 10% (4/41) prior tx, 8% (n=1/13) favorable risk, 11% (n=8/70) intermediate/poor risk (Table). 11 pts (13%: 9 PR, 1 uPR, 1 SD) were allocated to Arm A, of whom 5 (45%, 90% CI 20-73%) remained off Nivo at ≥ 1 yr. Of 57 pts (69%) allocated to Arm B, 2 pts converted to a PR (4%, 90% CI 1-11%), both of whom had prior tx and PD as best response to Nivo alone. Grade 3-4 treatment related adverse events (TrAE) occurred in 7% (n=6/83) on induction Nivo and in 23% (n=13/57) on Arm B (Nivo + Ipi). Conclusions: We cannot currently recommend a strategy of Nivo followed by response-based addition of Ipi due to the absence of CR and low PR/CR conversion rate (4%). Though a subset of pts treated with Nivo alone can maintain durable responses off tx at 1-yr, early Nivo discontinuation in the absence of toxicity cannot currently be recommended. Investigation into biomarkers to guide tx is ongoing. Clinical trial information: NCT03203473 . [Table: see text]

Abstract Introduction Multisession staged stereotactic radiosurgery (2-SSRS) represents an alternative approach for management of large brain metastases (LBMs), with potential theoretical advantages over fractionated SRS and represents an alternative to surgery in poor surgical candidates. We aimed to investigate the clinical efficacy and safety of 2-SSRS in patients with LBMs. Methods LBMs of patients treated with 2-SSRS between 2014 and 2020 were evaluated. Demographic, clinical, and radiologic information was obtained. Volumetric measurements at first SSRS, second SSRS, and follow-up imaging studies were obtained. Results Twenty-six patients with 28 LBMs were included in the study. Fifteen patients (58%) were male. Median age at 2-SSRS was 61 years (range: 31–84). Median marginal doses for first and second SSRS were 15 Gy (range: 12–18 Gy) and 15 Gy (range: 12–16 Gy), respectively. Median duration between sessions was 32 days. Two patients (8%) failed to receive their second SSRS due to local progression. Median tumor volumes at first SSRS, second SSRS, 3-month follow-up, and 6-month follow-up were 8.7 cm3 (range: 1.5–34.7 cm3), 3.3 cm3 (range: 0.8–26.1 cm3), 1.7 cm3 (range: 0.2–10.1 cm3), and 1.4 cm3 (range: .04–20.7 cm3), respectively. The median absolute and relative decrement between S-SRS sessions was 3.7 cm3 (range: 2.8–16.5 cm3) and 49.5% (range: 17.1- 87.1%), respectively. Overall, 26 of the 28 lesions (93%) demonstrated early local control following the first SSRS with 18 lesions (69%) demonstrating a decrease in volume of >30% and 3 lesions (12%) remaining stable. Six lesions (23%) showed disease progression. There were no grade 3 adverse events. Conclusions Our study supports the effectiveness and safety of 2-SSRS as a treatment modality for patients with large, symptomatic brain metastases, especially in non-surgical candidates. The local failure rate and low occurrence of adverse effects are comparable to other staged radiosurgery series.

8035 Background: NGR-hTNF, a selective antivascular agent, induces at low dose an initial vascular normalization that greatly enhances the intratumoral chemotherapy uptake, with synergistic effects that were noted especially in combination with cisplatin and gemcitabine. Methods: Chemo-naive patients (pts) with advanced NSCLC were stratified by histology (nonsquamous or squamous) and PS (0 or 1) and randomly assigned to receive cisplatin 80 mg/m2/d1 plus either pemetrexed 500 mg/m2/d1 (nonsquamous) or gemcitabine 1,250 mg/m2/d1+8 (squamous) every 3 weeks (q3w) for 6 cycles, with (arm A) or without (arm B) NGR-hTNF given at 0.8 μg/m2/d1/q3w until progression. Progression-free survival (PFS) was primary aim (1-β=80%, 1-sided α=10%, n=102). Secondary aims comprised adverse events (AEs), response rate (RR), and overall survival (OS). Results: Baseline characteristics in arm A (n=62) vs B (n=59) were: median age: 62 vs 63 years; men: 37 vs 39; PS 1: 23 vs 23; squamous: 18 v 17; smokers: 41 vs 43. For the nonsquamous stratum, 299 cycles were given in arm A (mean 7.0; range 1-20) and 192 in arm B (4.8; 1-6), while for the squamous stratum, 113 in arm A (6.7; 1-31) and 52 in arm B (3.5; 1-6). Rates of grade 3/4 AEs were similar (arm A vs B): neutropenia 13% vs 18%, anaemia 7% vs 4% and fatigue 7% vs 11%. No grade 3/4 AEs related to NGR-hTNF or bleeding/pulmonary hemorrhage events were reported in the squamous subset. With median follow-up time of 24.2 months, median PFS (5.8 vs 5.6 months; HR=0.92), RR (25% vs 21%) and 1-year OS (53% vs 53%) were similar between the two treatment arms. However, by predefined analysis in the squamous stratum, median PFS was 5.6 months for arm A and 4.3 months for arm B (hazard ratio, HR=0.75) and median OS was 14.2 months for arm A and 9.7 months for arm B (HR=0.49; p=0.07). In pts with squamous histology, RR was 38% for arm A and 27% for arm B (odds ratio=1.6), while the median changes in tumor size on treatment from baseline to 2nd, 4th and 6th cycle for arm A vs B were -32% vs -20%, -41% vs -19%, and -42% vs -14%, respectively. Conclusions: Clinical tolerability and benefit were noted in squamous NSCLC with NGR-hTNF plus cisplatin and gemcitabine, which deserve further investigation. Clinical trial information: NCT00994097.

e20503 Background: Most ALK+ NSCLC patients (pts) receiving CRZ eventually experience disease progression. Based on promising activity in a phase 1/2 trial, a randomized phase 2 trial of the ALK inhibitor BRG in pts with CRZ-refractory, advanced ALK+ NSCLC (ALTA; NCT02094573) was initiated. Responses and adverse events (AEs) varied with starting dose; therefore, ALTA was designed to evaluate 2 distinct BRG regimens. Methods: Pts were stratified by presence of baseline (BL) brain metastases and best response to prior CRZ and randomized 1:1 to receive BRG at 90 mg qd (arm A) or 180 mg qd with a 7-d lead-in at 90 mg (arm B). Primary endpoint was investigator-assessed confirmed objective response rate (ORR) per RECIST v1.1. Results: In 222 pts (arm A/B, n=112/n=110), median age was 51/57 y; 71%/67% had brain metastases. As of May 31, 2016, 51%/56% (A/B) continued to receive BRG; median follow-up was 10.2/11.0 mo. Table shows efficacy. In pts with measurable BL brain metastases (A/B, n=26/n=18), confirmed intracranial ORR was 46%/67%. Most common treatment-emergent AEs (A/B) were: nausea 36%/43%, diarrhea 21%/39%, cough 23%/36%, headache 28%/30%, vomiting 28%/26%; grade ≥3 AEs included increased CPK 3%/10%, hypertension 6%/6%, pneumonia 3%/5%, increased lipase 5%/3%. A subset of pulmonary AEs with early onset (median: Day 2) occurred in 14/219 (6%) treated pts (3%, grade ≥3); 7/14 pts were successfully retreated. Dose reductions (8%/23%, A/B) and discontinuations (3%/10%) due to AEs were reported. Conclusions: BRG showed substantial activity, robust PFS, and acceptable safety at both dose levels, with numerically improved efficacy (particularly PFS and intracranial ORR) at 180 mg (with lead-in). Clinical trial information: NCT02094573. [Table: see text]

Clinical Trial Information

9556 Background: Preliminary tepotinib data showed durable activity in pts with NSCLC with METex14 skipping prospectively identified by liquid (L+) or tissue (T+) biopsy. Having met target enrollment of ≥60 L+ pts & ≥60 T+ pts, we report primary data. Methods: VISION Cohort A enrolled pts with advanced EGFR/ALK wt, METex14 skipping NSCLC (asymptomatic brain metastases [BM] allowed), who received oral tepotinib 500 mg QD. On-study treatment decisions were based on investigator assessment (INV) of response. Primary endpoint was objective response rate (ORR) by independent review committee (IRC) analyzed in 3 primary ITT sets: L+ and/or T+, L+, T+. 2ary endpoints included ORR by INV, duration of response (DOR), disease control rate (DCR), PFS, OS, & safety. Preplanned analyses were performed in pts with BM at baseline (BL). BL/on-treatment ctDNA plasma samples (L+) were analyzed using a 73-gene NGS panel (Guardant360). Deep molecular responses (MR), defined as > 75% depletion of METex14, were compared with objective responses (OR). Results: By data cut-off (1 Oct 19) 151 pts received tepotinib (safety set); 99 L+/T+, 66 L+, 60 T+ pts comprised the 3 ITT sets with ≥6-month [m] follow-up. Across treatment lines (n = 44 1L, n = 55 ≥2L), primary ORR & mPFS [95% CI] in 99 L+/T+ pts were 43% [34–54] & 8.6 m [6.9–11.0] by IRC and 56% [45–66] & 9.5 m [6.7–13.5] by INV. ORR was similar in L+ or T+ pts (table) or in T+L− pts (n = 25): 40% [21–61] by IRC and 48% [28–69] by INV. Only 2 pts were T−L+. Outcomes were also comparable in pts with BM (n = 11): IRC ORR 55% [23–83] & mPFS 10.9 m [8.0–ne]. 34/51 pts (67%) with matched BL/on-treatment L+ samples had deep MR strongly associated with clinical response: 32/34 pts (94%) with MR had disease control (INV), including 29/34 pts (85%) with OR; 2/34 pts had progressive disease. Further biomarker data will be presented. Grade ≥3 treatment-related adverse events (TRAEs) were reported by 37/151 pts (25%). 13 pts (9%) discontinued due to TRAEs. Conclusions: Tepotinib is a promising targeted therapy with durable clinical activity and manageable toxicity in pts with METex14 skipping NSCLC L+ or T+, including pts with BM. High ORR & DCR in pts with ctDNA molecular responses support that MET inhibition in METex14+ tumor cells can lead to clinical benefit. Clinical trial information: NCT02864992 . [Table: see text]
