159 Background: Although the mTOR inhibitor everolimus (EVE) was generally well tolerated in combination with exemestane (EXE) in patients (pts) with HR+/HER2– advanced breast cancer, stomatitis and noninfectious pneumonitis (NIP) are the most clinically relevant and potentially dose-limiting toxicities. The incidence, grade, and clinical course of stomatitis and NIP among pts participating in the BOLERO-2 study are described. Methods: Pts were randomized 2:1 to receive EVE + EXE or placebo (PBO) + EXE. Incidence and severity of stomatitis and NIP, consequent dose interruptions/adjustments, study drug discontinuations, and time to resolution were recorded. Results: Stomatitis (any grade) occurred more frequently with EVE + EXE than with PBO + EXE (59% vs 12%, respectively). Grade 3 stomatitis occurred in 8% vs 1% of EVE + EXE vs PBO + EXE pts, respectively; no grade 4 events were reported. Onset of grade ≥ 2 stomatitis after treatment initiation was earlier for EVE + EXE arm vs PBO + EXE: median time was 15 d vs 24 d, respectively. For the EVE + EXE arm, 97% of pts with grade 3 stomatitis (n = 38) improved to ≤1 after a median of 13 d. Complete resolution was observed in 82% of pts after a median of 38 d. For the PBO + EXE arm, all pts with grade 3 stomatitis (n = 2) improved to ≤1 after a median of 18 d. Complete resolution was observed after a median of 29 d. 24% of pts on EVE + EXE required dose interruptions/adjustments vs 1% of pts on PBO + EXE, and 3% of pts (n = 13) discontinued EVE + EXE vs <1% of pts (n = 1) discontinuing PBO + EXE, all related to stomatitis. Overall, 16% in the EVE + EXE vs 0% in the PBO + EXE groups had a diagnosis consistent with NIP. For EVE + EXE, grade 1, 2, and 3 NIP occurred in 7%, 6%, and 3% of pts, respectively; no grade 4 events were reported. Complete resolution of NIP to grade ≤1 was recorded for all but 4 pts for whom NIP was still observed at last follow-up before study discontinuation. Overall, in the EVE + EXE arm, NIP was reason for dose interruption and treatment discontinuation in 7.5% and 5.6% of pts, respectively. Conclusions: In the BOLERO-2 study, stomatitis and NIP were of mild to moderate intensity and were generally reversible. Most incidents were successfully managed with palliative interventions and temporary dose modifications. Clinical trial information: NCT00863655.

558 Background: In BOLERO-2, adding everolimus (EVE) to exemestane (EXE) more than doubled progression-free survival without affecting quality of life vs EXE alone in postmenopausal women with hormone-receptor–positive advanced breast cancer who had recurrence or progression on/after nonsteroidal aromatase inhibitor therapy. Although mTOR inhibitors are generally well tolerated, stomatitis is one of their most clinically relevant and potentially dose-limiting toxicities (Sonis Cancer2010). The incidence, grade, and clinical course of stomatitis among patients (pts) participating in the BOLERO-2 study are described. Methods: Pts were randomized 2:1 to receive EVE+EXE or placebo (PBO)+EXE. Stomatitis incidence, severity, consequent dose interruptions/adjustments, study drug discontinuations, and time to resolution were recorded. Results: The median duration of EVE+EXE treatment exposure was 30 wk (range, 1-123 wk). Stomatitis (any grade) occurred more frequently with EVE+EXE than with PBO+EXE (59% vs 12%, respectively). Grade 3 stomatitis occurred in 8% vs 1% of pts receiving EVE+EXE vs PBO+EXE, respectively; no grade 4 was reported. Onset of grade ≥2 stomatitis after treatment initiation was earlier in the EVE+EXE arm vs the PBO+EXE arm: median time was 15d vs 24d, respectively. In the EVE+EXE arm, 97% of pts with grade 3 stomatitis (n=38) improved to ≤1 after a median of 13 d. Complete resolution was observed in 82% of these pts after a median of 38 d. In the PBO+EXE arm, all pts with grade 3 stomatitis (n=2) improved to ≤1 after a median of 18 d. Complete resolution was observed after a median of 29 d. Overall, 24% of pts in the EVE+EXE arm required dose interruptions/adjustments vs 1% of pts in the PBO+EXE arm, and 3% of pts (n=13) discontinued EVE+EXE vs <1% of pts (n=1) discontinuing PBO+EXE, all related to stomatitis. Conclusions: The BOLERO-2 data foster a new era of combining targeted and endocrine therapies. In the study, treatment-emergent stomatitis was of mild to moderate intensity, occurred shortly after treatment initiation, and was generally reversible. Most incidents were successfully managed with palliative interventions and temporary dose modifications. Oral hygiene and other preventive measures are recommended.

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.

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.

71 Background: Galeterone is a first-in-class multitargeted oral steroid analog; it suppresses prostate cancer by a combination of AR modulation (antagonism and degradation) and CYP17 inhibition. Safety and proof of concept of galeterone in CRPC was assessed in ARMOR1. Galeterone was reformulated by spray dry dispersion technology (SDD) to optimize PK and remove food effect. ARMOR2 (NCT 01709734) is an open label, 2-part phase 2 trial that evaluates safety and efficacy of SDD galeterone in 4 populations of CRPC patients. These results report Part 1. Methods: Objectives of Part 1: confirm dose equivalence of SDD formulation with evaluation of PK, safety and PSA response. Metastatic (M1) and non-metastatic (M0) treatment naïve CRPC pts enrolled to groups of 1,700, 2,550 or 3,400 mg PO daily. An abiraterone refractory (Abi-R) group of 3 patients opened at 2,550mg. Results: 28 were enrolled in part 1. Safety: All groups were safe by IMC assessment. There were 4 grade 3 adverse events. 2 were unrelated to study drug. 2 had transient G3 ALT elevations (did not recur with rechallenge). There was no AME: supplemental steroids were not required. G4 angioedema occurred in a pt receiving lisinopril (known association with angioedema). Efficacy: PSA response was improved compared to ARMOR1 (AACR 2012. Taplin et al abstract: CT-07). At early follow up Abi-R pts showed improvements in PSA with 1 PSA30% response, 2 with stablized PSA (decline in PSA-V from +0.44 to -0.39 ng/day). Conclusions: Galeterone in SDD formulation is tolerated at doses up to 3,400mg daily. SDD galeterone provides improved PSA response and durability vs. prior formulation. There is evidence of activity in abiraterone refractory patients. Clinical trial information: 01709734. [Table: see text]

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.

507 Background: ASPECCT demonstrated that panitumumab (pmab) was noninferior to cetuximab (cmab) for overall survival (OS). Ad hoc analyses from ASPECCT suggested that hypomag was associated with better outcomes for pmab and cmab (Price 2015). However, results from the phase 3 NCIC CTG/AGITG CO.17 trial indicated hypomag at day 28 was associated with worse outcomes for cmab (Vickers 2013). Methods: Patients (pts) with chemorefractory WT KRASexon 2 mCRC were randomized 1:1 to receive pmab or cmab. Ad hoc analyses by hypomag were performed from the final analysis of ASPECCT at week 5, consistent with the NCIC CTG/AGITG CO.17 trial analysis (Vickers, 2013). Results: 999 pts were treated: 496 received pmab and 503 received cmab. Any grade hypomag was 29.0% and grade ≥3 was 7.3% in the pmab arm vs 19.3% and 2.8% in the cmab arm, respectively. In the pmab arm, 1.2% of pts discontinued treatment and 5% of pts had dose modifications due to hypomag vs 0.4% and 3% in the cmab arm, respectively. Efficacy results by hypomag are shown (Table). Conclusions: In ASPECCT, rates of hypomag were higher in the pmab vs the cmab arm. Pts who developed any grade hypomag with pmab or cmab had longer median OS compared with those pts who did not. Consistent with previous analyses, development of hypomag at week 5 was associated with worse median OS for cmab. Clinical trial information: NCT01001377. [Table: see text]

12020 Background: Previous randomized trials in cancer patients suggest that DOACs are non-inferior to LMWH for preventing recurrent VTE but have higher risk of bleeding. However, the balance of benefits and burdens remains uncertain. Objective: The CANVAS pragmatic trial compared recurrent VTE, bleeding and death in cancer patients following an initial VTE treated with either DOAC or LMWH therapy. Methods: CANVAS was an unblinded hybrid comparative effectiveness non-inferiority trial, with randomized and preference cohorts. Between 12/16 and 4/20, 671 participants were randomized and followed for 6-months. Between 12/16 and 12/17, 140 participants declined randomization, chose their preferred anticoagulant and were followed for 6-months. The preference cohort was closed when predetermined stopping criteria were met. Final follow-up was 11/30/20. Randomized patients were assigned 1:1 to receive either a DOAC or a LMWH. If assigned to LMWH, transitions to warfarin were allowed. Physicians and patients could choose among any DOAC or LMWH. Doses were suggested based on FDA-approved labeling but not mandated. Patients from 67 practices in the US with any invasive solid tumor, lymphoma, multiple myeloma or CLL and a diagnosis of symptomatic or radiographically detected VTE within 30 days of enrollment were eligible. The 1° analysis was conducted in the randomized modified-into to treat popululation, (all subjects who received study drug). The 1° outcome was recurrent VTE. The aim was to establish noninferiority of anticoagulation with a DOAC as defined by the upper limit of the 2-sided 90% CI for the difference in the event rate at 6 months of < 3%. Secondary outcomes included death and bleeding. Hypothesis testing included only the randomized cohort but propensity score adjusted results for the preference and combined cohorts are also shown. Results: The non-inferiority criteria for recurrent VTE was met. Conclusions: Among adult cancer patients with VTE, the use of a DOAC compared with a LMWH resulted in a noninferior risk of recurrent VTE with no differences in rates of bleeding or death in randomized patients. Clinical trial information: NCT02744092. [Table: see text]

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.

9016 Background: 1L NIVO + IPI was shown to provide durable long-term overall survival (OS) benefit vs chemo regardless of tumor programmed death ligand 1 (PD-L1) expression in patients (pts) with advanced NSCLC in CheckMate 227 Part 1 (NCT02477826); 3-year OS rates were 33% vs 22% in pts with PD-L1 ≥ 1% (HR, 0.79 [95% CI, 0.67–0.93]) and 34% vs 15% in pts with PD-L1 < 1% (HR, 0.64 [95% CI, 0.51–0.81]). Here we report updated results from the study with 4 years’ minimum follow-up. Methods: Adults with previously untreated stage IV / recurrent NSCLC, no known EGFR/ ALK alterations , and ECOG performance status ≤ 1 were enrolled; pts were stratified by squamous (SQ) and non-squamous (NSQ) histology. Pts with PD-L1 ≥ 1% (n = 1189) were randomized 1:1:1 to receive NIVO (3 mg/kg Q2W) + IPI (1 mg/kg Q6W), NIVO alone (240 mg Q2W), or chemo. Pts with PD-L1 < 1% (n = 550) were randomized 1:1:1 to receive NIVO + IPI, NIVO (360 mg Q3W) + chemo, or chemo. OS with NIVO + IPI vs chemo in pts with PD-L1 ≥ 1% was the primary endpoint. Results: With minimum follow-up of 49.4 months (database lock, Feb 18, 2021), pts were at least 2 years beyond the protocol-specified end of immunotherapy treatment. Pts with PD-L1 ≥ 1% continued to show durable benefit with NIVO + IPI vs chemo (HR, 0.76 [95% CI, 0.65–0.90]); 4-year OS rates were 29% (NIVO + IPI), 21% (NIVO), and 18% (chemo). At 4 years, 14% (NIVO + IPI), 10% (NIVO), and 4% (chemo) remained progression free. Among responders, 34%, 30%, and 7% remained in response, respectively. In an exploratory analysis in pts with PD-L1 ≥ 50%, 4-year OS rates were 37% (NIVO + IPI), 26% (NIVO), and 20% (chemo). In pts with PD-L1 < 1%, OS HR for NIVO + IPI vs chemo was 0.64 (95% CI, 0.51–0.81); 4-year OS rates were 24% (NIVO + IPI), 13% (NIVO + chemo) and 10% (chemo). At 4 years, 12% (NIVO + IPI), 7% (NIVO + chemo), and 0% (chemo) remained progression free. Among responders, 31%, 13%, and 0% remained in response, respectively. Among pts who progressed on NIVO + IPI vs chemo, 7% vs 40% (PD-L1 ≥ 1%), and 9% vs 33% (PD-L1 < 1%), received subsequent immunotherapy. Benefit with NIVO + IPI vs chemo was observed for both SQ and NSQ histology (Table). With long-term follow-up, no new safety signals were identified. Conclusions: With 4 years’ minimum follow-up, 1L NIVO + IPI continued to provide durable, long-term OS benefit vs chemo in pts with advanced NSCLC regardless of PD-L1 expression or histology.

6568 Background: After a minimum follow-up of 48 months (mos), the CheckMate 214 trial (phase 3, NCT02231749) continued to demonstrate a significant overall (OS) and progression-free (PFS) survival benefit for N+I vs. SUN in aRCC patients (pts) with intermediate (I) or poor (P) International Metastatic RCC Database Consortium (IMDC) risk factors (median OS: 48.1 vs. 26.6 mos, HR: 0.65, 95% confidence interval [95% CI]: 0.54, 0.78; 48-mos PFS: 32.7% vs. 12.3%, HR: 0.74, 95% CI: 0.62, 0.88) (Albiges et al. ESMO Open 2020). To further understand the clinical benefits and risks of N+I vs. SUN, we evaluated the Q-TWiST over time using up to 57 mos of follow-up in CheckMate 214. Methods: OS was partitioned into 3 states: time with any grade 3 or 4 adverse events (TOX), time without symptoms of disease or toxicity (TWiST), and time after progression (REL). The Q-TWiST is a metric that combines the quantity and quality (i.e., “utility”) of time spent in each of the 3 states TWiST, TOX, and REL. Prior research (Revicki et al, Qual Life Res, 2006) has established that relative gains in Q-TWiST (i.e., Q-TWiST gain divided by OS in SUN) of ≥ 10% and ≥ 15% can be considered as “clinically important” and “clearly clinically important”, respectively. Non-parametric bootstrapping was used to generate 95% CIs. To observe changes in quality-adjusted survival gains over time, absolute and relative Q-TWiST were calculated up to 57 mos at intervals of 12-mos. Results: With 57-mos follow-up, compared to SUN pts, N+I pts (N = 847) had significantly longer time in TWiST state (+7.1 mos [95% CI: 4.2, 10.4]). The between-group differences in TOX state (0.3 mos [95% CI: -0.2, 0.8]) and REL state (-1.2 mos [95% CI: -4.1, 1.5]) were not statistically significant. The Q-TWiST gain in the N+I vs. SUN arms was 6.6 mos (95% CI: 4.1, 9.4), resulting in a 21.2% relative gain. Q-TWiST gains progressively increased over the follow-up period and exceeded the “clinically important” threshold around 27 mos (Table). These gains were driven by steady increases in TWiST gains from 0.4 mos (after 12 mos) to 7.1 mos (after 57 mos). Conclusions: In CheckMate 214, N+I resulted in a statistically significant and “clearly clinically important (≥ 15%)” longer quality-adjusted survival vs. SUN, which increased over the longer follow-up time. Q-TWiST gains were primarily driven by time in “good” health (i.e., TWiST), which largely resulted from the long-term PFS benefits seen for N+I vs. SUN. Clinical trial information: NCT02231749.
