5062 Background: Tivozanib (T) is a potent and highly selective VEGFR inhibitor. TIVO-3 is a phase 3 study designed to compare the efficacy and safety of T with those of sorafenib (S) as 3rd and 4th line therapy in patients with metastatic RCC. Methods: Subjects with RCC who failed 2 or 3 prior systemic regimens, one of which included a VEGFR TKI other than S or T, were stratified by IMDC risk category and type of prior therapy (two TKIs; TKI plus checkpoint inhibitor (CPI); TKI plus other) then randomized in a 1:1 ratio to T or S. Results: The 2 arms were well balanced for demographics and prior cancer history. 60% of subjects had 2 prior lines of therapy and 40% had 3 prior lines. 26% had prior treatment with a CPI. Patients treated with T demonstrated PFS superiority compared to S, 5.6 (95% CI 7.3 - 5.3) v. 3.9 mos (95% CI 5.6 – 3.7; HR 0.73; p=0.02). ORR was 18% for T compared to 8% for S (p=0.02). 44% of T treated subjects experienced a grade 3 treatment-related adverse event compared to 55% for S. The predefined, interim analysis for OS performed two years after enrollment was closed had a HR of 0.99 based on 227 events. The final analysis will be presented based on an estimate of 263 events. Conclusions: T is superior to S as measured by PFS; 2-year PFS, and ORR in this heavily-treated/relapsed or refractory RCC population and is better tolerated than S. Final OS data will be updated prior to presentation. Clinical trial information: 02627963 .

234 Background: MM-398 is a nanoliposomal encapsulation of irinotecan. OS in the ITT population was significantly longer with MM-398+5FU/LV over 5FU/LV alone, and the most frequent grade 3+ AEs included neutropenia, fatigue, and GI effects (diarrhea and vomiting). Expanded, pre-specified analyses of the Phase 3 study are presented. Methods: Patients (n=417) with mPAC previously treated with gemcitabine-based therapy, were randomized 1:1:1 in an open-label study to receive: (A) MM-398 (120 mg/m2 IV over 90 min) q3w; (B) 5FU (2,000 mg/m2 over 24 h) plus racemic leucovorin (LV) (200 mg/m2 over 30 min) x 4w followed by 2w rest; or (C) combination of MM-398 (80 mg/m2 IV over 90 min) prior to 5FU (2,400 mg/m2 over 46 h) and racemic LV (400 mg/m2 over 30 min) q2w. The primary endpoint was OS. The Intent To Treat (ITT) population included all randomized patients; the Per Protocol (PP) population included patients who received at least 80% of the target dose in the first 6 weeks and did not violate any inclusion/exclusion criteria. Results: Analysis of the PP populations confirmed the favorable OS, which was also reflected by the PFS, ORR and CA19-9 levels, of the combination MM-398+5FU/LV arm over the control 5FU/LV arm. The MM-398 monotherapy arm did not show a statistically significant improvement in OS compared with the control arm. Analysis of subgroups, based on pretreatment characteristics including stage at diagnosis, time since initial histological diagnosis, prior lines of therapy, time since last prior therapy, and CA19-9 levels, consistently favored OS for the MM-398+5FU/LV arm over the 5FU/LV arm. Conclusions: Expanded analysis of the PP population and sensitivity analyses support the favorability of MM-398+5FU/LV over 5FU/LV, with a manageable safety profile. Clinical trial information: NCT01494506. [Table: see text]

Nonsquamous Nsclc

9582 Background: The phase III KEYNOTE-189 study (NCT02578680), showed significant improvements in OS and PFS with pembro + chemo vs placebo + chemo in pts with previously untreated metastatic nonsquamous NSCLC without sensitizing EGFR/ALK mutations. We report the protocol-specified final analysis of KEYNOTE-189. Methods: Pts were randomized 2:1 to receive 35 cycles of pembro 200 mg Q3W (n = 410) or placebo Q3W (n = 206) plus 4 cycles of pemetrexed (pem) and carboplatin/cisplatin followed by maintenance pem. Pts in the placebo + chemo arm could crossover to pembro upon PD. PFS and OS were primary endpoints; ORR was a secondary endpoint. PFS2 (time from randomization to objective tumor progression on next-line treatment/death), was an exploratory endpoint. Results: At data cutoff (May 20, 2019), median (range) time from randomization to data cutoff was 31.0 (26.5–38.8) mo. 17 pts in the pembro + chemo arm and 1 pt in the placebo + chemo arm were receiving initially assigned treatment; 84 pts crossed over to pembro. Median (95% CI) OS (22.0 [19.5–24.5] vs 10.6 [8.7–13.6] mo; HR 0.56 [95% CI, 0.46–0.69]) and PFS (9.0 [8.1–10.4] vs 4.9 [4.7–5.5] mo; HR 0.49 [95% CI, 0.41–0.59]) were longer with pembro + chemo vs placebo + chemo (Table). The 2-y OS rate was 45.7% vs 27.3% and the 2-y PFS rate was 22.0% vs 3.4%. ORR was 48.3% with pembro + chemo vs 19.9% with placebo + chemo. 56 pts in the pembro + chemo arm completed 35 cycles of pembro among whom ORR was 85.7% (4 CR, 44 PR, 8 SD) and median OS was not reached. 292 (72.1%) pts in the pembro + chemo arm and 135 (66.8%) pts in the placebo + chemo arm had grade 3–5 AEs. Conclusions: Pembro + chemo continued to show improved outcomes in OS, PFS, ORR and PFS2 compared with placebo + chemo, with manageable toxicity. These findings support first-line pembro + chemo in pts with previously untreated metastatic nonsquamous NSCLC. Clinical trial information: NCT02578680 . [Table: see text]

5500 Background: IC is associated with lower distant failure (DF) rates in SCCHN but an improvement in overall survival (OS) has not been validated. The goal of this trial was to determine whether IC prior to chemoradiotherapy (CRT) improves survival compared to CRT alone. Methods: In this phase 3, open-label trial, subjects with pathologically confirmed SCCHN; N2/N3 disease without metastases; no prior therapy; KPS ³ 70%; and intact organ function were randomized to CRT alone (CRT arm) [5 days of D (25 mg/m2), F (600 mg/m2), hydroxyurea (500 mg BID), and RT (150 cGy BID) followed by a 9 day break] or to 2 cycles of IC [D (75 mg/m2), P (75 mg/m2), F (750 mg/m2 day 1-5)] followed by the same CRT (IC arm). Primary endpoint was OS. Secondary endpoints included DF free survival, failure pattern, and recurrence-free survival (RFS). 280 subjects provided 80% power to detect a hazard ratio HR=0.5 for OS (a=0.05). Results: 280 subjects were accrued from 2004-09 with minimum follow-up 24 months. Of 142 patients randomized to IC, 91% received 2 cycles and 87% continued to CRT. Treatment adherence during CRT was high for docetaxel and hydroxyurea, but fewer than 75% of the patients received target dose of 5FU in both arms. RT was delivered without major deviations in 94% and 95% of patients on IC and CRT arms, respectively. The most common grade 3-4 toxicities during IC were febrile neutropenia (9%) and mucositis (8%), and during CRT (both arms combined) they were mucositis (45%), dermatitis (19%), and leukopenia (17%). Only grade 3-4 leukopenia and neutropenia rates were significantly higher in IC (p=0.002 and p=0.02, respectively). Table shows efficacy. Conclusions: High survival rates were observed in both arms. Further analysis and follow-up may provide insight into why the significant decrease in DF did not translate into improved OS. [Table: see text]

Abstract Efficacy and safety of azacitidine (Vidaza®), at the FDA-approved dosing schedule of 75 mg/m2/day x 7 days every 28 days, was demonstrated in a phase III CALGB study by Silverman et al (JCO2002; 20:2429) for the treatment of myelodysplastic syndromes (MDS). The objective of this phase II, multicenter, randomized, open-label study in all FAB subtypes of MDS was to study the treatment response and safety of 3 alternative subcutaneous azacitidine dosing schedules, eliminating the need for weekend azacitidine injections. Patients were randomized to either AZA 5-2-2 (75 mg/m2 day x 5 days, followed by 2 days no treatment, followed by 75 mg/m2/day x 2 days), AZA 5-2-5 (50 mg/m2/day x 5 days, followed by 2 days no treatment, followed by 50 mg/m2/day x 5 days) or AZA 5 (75 mg/m2/day x 5 days). After 6 cycles of azacitidine, patients meeting International Working Group MDS response/improvement criteria (Blood2000; 96:3671), defined as complete remission, partial remission, stable disease, or hematologic improvement, were eligible to receive an additional 12 cycles. As of July 1st, a total of 106 patients have been randomized in the AZA 5-2-2 (n=33), AZA 5-2-5 (n=35), and AZA 5 (n=38) treatment arms. Based on FAB classification, most patients have RA (42%, 45/106) or RAEB (30%, 32/106). Of 80 patients who have received ≥2 cycles of treatment, hematologic improvement (major or minor in at least 1 cell line) occurred in 58% (46/80) of the patients (Table). Median time to improvement in the 3 arms ranged between 1 and 3 cycles (AZA 5-2-2: 1.1, AZA 5-2-5: 3.0, AZA 5: 2.6). Of 38 patients who were RBC transfusion dependent at baseline, 27 (71%) became independent (AZA 5-2-2: 59%, 10/17, AZA 5-2-5: 89%, 8/9; AZA 5: 75%, 9/12). The most common grade 3 or 4 events included neutropenia 29%, 28/98 (AZA 5-2-2: 44%, 14/32; AZA 5-2-5: 20%, 6/30, and AZA 5: 22%, 8/36), thrombocytopenia 15%, 15/98 (AZA 5-2-2: 28%, 9/32; AZA 5-2-5: 10%, 3/30, and AZA 5: 8%, 3/36) and anemia 12%, 12/98 (AZA 5-2-2: 16%, 5/32; AZA 5-2-5: 17%, 5/30, and AZA 5: 6%, 2/36). The frequency of patients with a grade 3 or 4 infection was 15%, 15/98 (AZA 5-2-2: 19%, 6/32; AZA 5-2-5: 23%, 7/30; AZA 5: 6%, 2/36) or hemorrhage was 4%, 4/98 (AZA 5-2-2: 6%, 2/32; AZA 5-2-5: 7%, 2/30; AZA 5: 0/36). Updated data will be available at the time of the meeting. Based on preliminary results, these data indicate that the 3 alternative dosing schedules provide clinical benefit (i.e., transfusion independence and hematologic improvement) and are consistent with the FDA-approved 75 mg/m2/day x 7 days dosing results from previous CALGB studies.

5506 Background: Data from a randomized Phase II trial (NCT00628251) of olaparib (capsules, 200 or 400 mg bid, n=32 per arm) vs pegylated liposomal doxorubicin (PLD, n=33) in gBRCAm OC pts with recurrence ≤12 months after prior platinum therapy indicated efficacy for olaparib (Kaye et al. JCO 2012). However, the efficacy of PLD was higher than previously reported in this setting. We led a confirmatory Phase III, open-label study of olaparib vs non-platinum chemotherapy in gBRCAm PSR OC pts (NCT02282020). Methods: Pts were randomized (2:1) to olaparib tablets (300 mg bid) or chemotherapy treatment of physician’s choice (TPC) (paclitaxel [P; 80 mg/m2 on day 1 (D1), D8, D15, D22 every 4 weeks (q4w)], topotecan [T; 4 mg/m2 D1, D8, D15 q4w], gemcitabine [G; 1000 mg/m2 D1, D8, D15 q4w] or PLD [50 mg/m2 D1 q4w]) until progression, stratified by: TPC, prior lines of chemotherapy (2–3 vs ≥4) and platinum-free interval (6–12 vs >12 months). Primary endpoint: ORR (blinded independent central review [BICR]). Secondary endpoints included PFS and safety. Results: 266 gBRCAm PSR OC pts were randomized (olaparib, n=178; TPC, n=88 [ PLD, n=47; P, n=20; G, n=13; T, n=8]); 12 in the TPC arm withdrew before receiving study treatment. 223 pts (84%) had baseline BICR measurable disease (olaparib, n=151; TPC, n=72). ORR was 72% with olaparib vs 51% with TPC (OR 2.53, 95% CI 1.40–4.58; P=0.002). HR for PFS by BICR was 0.62 (95% CI 0.43–0.91; P=0.013; median 13.4 vs 9.2 months [olaparib vs TPC]) and by investigator assessment was 0.49 (95% CI 0.35–0.70; P<0.001; median 13.2 vs 8.5 months, respectively). Most common adverse events (AEs) with olaparib were nausea (65% vs 34% [TPC]) and anemia (50% vs 25%) and with TPC were palmar-plantar erythrodysesthesia (PPE; 36% vs 1% [olaparib]) and nausea. Most common grade ≥3 AEs in either arm were anemia (21% [olaparib] vs 0 [TPC]), PPE (0 vs 12%) and neutropenia (6% vs 11%). For olaparib vs TPC, serious AEs were reported by 24% vs 18% and AEs led to treatment discontinuation in 7% vs 20%. Conclusions: Pts with gBRCAm PSR OC receiving olaparib monotherapy had a significant, clinically relevant improvement in ORR and PFS vs TPC, with no new safety signals. Clinical trial information: NCT02282020.

1040 Background: Despite advances, pretreated HER2+ MBC remains incurable with ongoing need for new therapies. Investigational M has similar HER2 binding and antiproliferative effects as T. Relative to T, M Fc engineering increases binding affinity for both variants of activating Fc receptor (FcR) CD16A and decreases affinity for inhibitory FcR CD32B, coordinately activating innate and adaptive immunity. In a Phase 3 (P3) trial, M prolonged PFS over T (Table). Second interim OS results from Sept 2019 also favor M (hazard ratio [HR], 0.89; 95% CI 0.69–1.13; nominal P=0.326). Methods: SOPHIA (NCT02492711), an open-label P3 trial, enrolled pts with HER2+ MBC after pertuzumab and 1–3 lines of prior treatment (Tx) for MBC. Randomization was 1:1 to M (15 mg/kg IV q3w + Ctx) or T (6 [8 for loading dose] mg/kg IV q3w + Ctx), stratified by met sites (≤2, >2), lines of Tx for met disease (≤2, >2), and Ctx choice, including capecitabine (Cap), eribulin (Eri), gemcitabine (Gem), or vinorelbine (Vin). Primary endpoints were central blinded PFS and OS, assessed sequentially using the stratified log-rank test. Results: Investigator chemotherapy choices and results by chemotherapy are shown in the table. Subjects receiving Eri and Gem had the lowest PFS hazards ratios (HRs), favoring M over T, although no statistical significance of individual chemotherapy subgroups was seen. There was variable toxicity among Ctx subgroups, and fewer subjects receiving Cap had Ctx related Grade 3 or higher (>=Gr 3) AEs. In this unblinded study, more subjects on M than T in all subgroups discontinued Ctx while continuing study antibody. Conclusions: In combination with chemotherapy in pretreated HER2+ MBC, M improved PFS over T. Safety was manageable in all Ctx subgroups. Differences among HRs for chemotherapy subgroups may be driven by selection bias and/or sensitivity differences. Clinical trial information: NCT02492711 . [Table: see text]

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]

LBA8502 Background: Treatments are limited and outcomes poor in rituximab-refractory (Rit-Ref) iNHL. Bendamustine (B) has a 9 mo median PFS and 10 mo response duration in ph II trials. Obinutuzumab (GA101/Gazyva [G]) is a glycoengineered type II aCD20 mAb with activity and acceptable safety in Rit-Ref NHL. Methods: GADOLIN (NCT01059630) is a ph III open label study in pts with CD20+ Rit-Ref iNHL. In the B arm, pts received B 120 mg/m2 (d1+2, c1–6) alone; GB arm pts received B 90 mg/m2 (d1+2, c1–6) with G 1000 mg (d1, 8, 15 c1, d1 c2–6) for up to six 28d cycles. Non-PD GB pts then received G monotherapy every 2 mo for up to 2 yrs. Primary endpoint was PFS assessed by an independent radiology facility (IRF), with 80% power to detect 43% improvement in median PFS. Results: In the protocol specified interim analysis, 396 pts were randomized to receive B (n = 202 [198 treated]) or GB (n = 194). The IDMC recommended to unblind the study as the primary endpoint had been reached (4 Feb 2015). Baseline characteristics were balanced between arms. Median age was 63 yrs and pts had a median of 2 prior therapies. Median observation time was 20 mo (B) and 22 mo (GB). IRF-assessed median PFS was 14.9 mo (B) and not reached (NR) for GB (HR 0.55, 95% CI 0.4–0.74; p = 0.00011). Median investigator-assessed PFS was 14 mo for B and 29 mo for GB (HR 0.52, 95% CI 0.39–0.70; p < 0.0001). There were no significant differences in IRF-assessed ORR (63.0% B vs 69.1% GB) or CR (12.2% B vs 11.2% GB) at end of induction, in IRF-assessed best overall response up to 12 mo from start of treatment (76.6% B vs 78.6% GB), or in preliminary OS (median OS NR in either arm). In the treatment period, there were fewer Grade ≥ 3 adverse events with B than GB (62.1% B vs 68% GB), notably neutropenia (26.3% B vs 33.0% GB) and infusion-related reactions (3.5% B vs 8.8% GB), but more Grade ≥ 3 thrombocytopenia (16.2% B vs 10.8% GB), anemia (10.1% B vs 7.7% GB) and pneumonia (5.6% B vs 2.6% GB). Conclusions: G combined with B (90 mg/m2) followed by G maintenance significantly improved PFS vs B alone (120 mg/m2) in Rit-Ref iNHL. The clinically meaningful PFS improvement with GB is the first randomized evidence of benefit for a novel aCD20 mAb in Rit-Ref iNHL. Clinical trial information: NCT01059630.

37 Background: NIVACOR trial is an open-label, multicentric Italian phase II trial of FOLFOXIRI/bevacizumab in association with an anti-PD1 antibody, nivolumab, in patients (pts) with metastatic colorectal cancer (mCRC). We report preliminary safety analysis by an Independent Monitoring Committee. Methods: Pts with mCRC RAS or BRAF mutated, regardless microsatellite status and eligible to receive a first line treatment will be enrolled. FOLFOXIRI/bevacizumab (BEV) in association with nivolumab (NIV) was administered every 2 weeks for 8 cycles (induction) followed by BEV plus NIV every 2 weeks (maintenance) until PD or unacceptable toxicities. BEV was administered intravenously at dose of 5 mg/kg and NIV intravenously as a flat dose of 240 mg every 2 weeks. The primary endpoint was the ORR. The safety is assessed after the inclusion of the 10th patient, receiving ≥1 dose. Results: As of September 20, 2020, 25/70 pts are enrolled. The first 10 pts were evaluated for preliminary safety analysis. Median age was 58 years (32-66), 60% of pts were male, median cycles of treatment was 5.5 (1-9). 100% were KRAS G12D mut and BRAF wild type, respectively, and 2% MSI-H/dMMR. 7/10 pts experienced at least one AE related to FOLFOXIRI/BEV and 2/10 related to NIV. The most frequent grade 1-2 AEs related to FOLFOXIRI/BEV were nausea and vomiting 4(57%), fatigue 5(71%), and diarrhea 5(71%); 3(43%) pts had grade 3-4 neutropenia, and 1(14%) febrile neutropenia. Only 2 pts developed grade 1-2 AEs related to NIV represented by rash (50%) and salivary gland infection (50%); no grade 3-4 was reported. One of pts with dose delay because of serious AES (proteinuria) BEV related, and one patient discontinued due to serious AEs (ileo-urethral fistula) not related to NIV. Conclusions: Combination of FOLFOXIRI/BEV and NIV was generally well tolerated and showed an acceptable toxicity profile. The final analysis will be scheduled at the end of enrollment. Clinical trial information: NCT04072198.
