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]

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]

533^ Background: Vascular endothelial growth factor (VEGF) and the VEGF receptor-2 (VEGFR-2) are overexpressed in CRC and mediate angiogenesis. Ramucirumab (RAM; IMC-1121B) is a fully human IgG1 MAb that inhibits binding of VEGF ligands to VEGFR-2 and inhibits VEGFR-2 activation and signaling. In preclinical CRC models VEGFR-2 inhibition confers antitumor activity. RAM was administered with mFOLFOX-6 as 1st-line therapy (rx) in mCRC. Methods: Eligible pts had mCRC with no prior chemo Rx (prior adjuvant rx was allowed), at least 1 measurable target lesion by RECIST v1.0, ECOG PS 0-1, and adequate organ function. Pts received RAM (8 mg/kg IV on D1), oxaliplatin (85 mg/m² IV on D1), folinic acid (400 mg/m² IV on D1), fluorouracil (5-FU, 400 mg/m² bolus followed by 2400 mg/m² continuous infusion over 46 hours on D1). Rx cycles were q2w and tumor assessments were q8w. Endpoints included progression-free survival (PFS), objective response rate (ORR), overall survival (OS), safety, and pharmacokinetics/immunogenicity. Sample size was based on an improved median (medn) PFS from 8 to 11 months (m). Results: 48 pts received therapy. All were white; 25 M/23 F; median age 60.5 y. ECOG PS was 0/1 in 30/18 pts. 42 pts (88%) had metastatic disease, with liver (79%) and lung (35%) as most frequent sites. 13 (27%) pts had liver-only mCRC. The most frequently observed RAM-related adverse events (AEs) included hypertension 46% (15% Grade [G] ≥3); diarrhea 31% (2% G≥3); and nausea and infusion-related reactions, each 19% (0% G≥3). 2 pts died on study due to acute MI or cardiopulmonary arrest. Medn PFS was 11.5 m (9-13 m 95% CI) with 1-yr PFS of 48% (32-62% 95% CI). ORR: 67% (52-80% 95% CI); disease control rate (DCR: CR+PR+SD): 94% (83-99% 95% CI; 5 pts had CR, 27 had PR and 13 had SD). Medn duration of response was 11.0 m (7-12 m 95% CI). One-year OS was 85% (72-93% 95% CI). As of 4/15/2011, 2 pts continued to receive rx, 20 had died and 28 (58.3%) remained alive. Conclusions: RAM combined with mFOLFOX-6 was reasonably tolerated in pts with mCRC. Median PFS exceeds 11 m. PFS, ORR, and DCR are encouraging and favor investigation of this regimen and of RAM in mCRC.

4570 Background: KEYNOTE-427 (NCT02853344) is an open-label, single-arm, phase 2 study to evaluate efficacy and safety of first-line single-agent pembro, a programmed death 1 (PD-1) inhibitor, in patients (pts) with ccRCC (cohort A) and non–clear cell RCC (cohort B). Updated follow up from cohort A are presented. Methods: Pts with histologically confirmed ccRCC, measurable per RECIST v1.1, and no prior systemic therapy were eligible. Pts received pembro 200 mg IV Q3W for 2 y or until confirmed progressive disease, unacceptable toxicity, or pt decision to withdraw. Primary end point was objective response rate (ORR; per RECIST v1.1 blinded independent central review). Additional end points included duration of response (DOR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results: 110 pts enrolled; median (range) follow-up was 18.0 (2.5-22.7) mo. Median age (range) was 64 (29-87); 38.2%, 47.3%, and 14.5% had favorable, intermediate, and poor IMDC risk, respectively; 47.3% were PD-L1 positive. Confirmed ORR was 36.4% with 3 (2.7%) CRs and 37 (33.6%) PRs. Median DOR was not reached. Median PFS was 7.1 mo (95% CI, 5.6-11.0) and median OS was not reached. Results by IMDC category are outlined in the table. By PD-L1 status, confirmed ORR was 44.2% and 29.3% for positive and negative, respectively. By sarcomatoid differentiation (n=11), confirmed ORR was 63.6%. Treatment-related AEs occurred in 80.9%, with pruritus (28.2%) and fatigue (28.2%) most commonly reported. One pt died of treatment-related pneumonitis. Conclusions: With a median 18-months’ follow up, first-line pembro monotherapy continued to show antitumor activity in pts with ccRCC. Meaningful responses were observed in pts with intermediate/poor IMDC risk, PD-L1 positive and sarcomatoid differentiated tumors. Safety profile was comparable to previously reported. Clinical trial information: NCT02853344. [Table: see text]

3505 Background: T-DXd is an antibody–drug conjugate of a humanized anti-HER2 antibody bound to a topoisomerase I inhibitor by a cleavable linker. The primary analysis of DESTINY-CRC01 (DS8201-A-J203; NCT03384940), a phase 2, open-label, multicenter study of T-DXd in pts with HER2-expressing mCRC showed promising antitumor activity and a manageable safety profile (cohort A median follow-up [FU], 27.1 weeks; Siena S, ASCO 2020). We present updated longer-term efficacy and safety data. Methods: Pts had centrally confirmed HER2-expressing, RAS wild-type mCRC that progressed after ≥2 prior regimens. 6.4 mg/kg of T-DXd was administered every 3 weeks (Q3W) in 3 cohorts (A: HER2 IHC3+ or IHC2+/ISH+; B: IHC2+/ISH−; C: IHC1+). The primary end point was confirmed objective response rate (ORR) by independent central review in cohort A. Secondary end points were disease control rate (DCR; CR + PR + SD), duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Results: At data cutoff (Dec 28, 2020), 86 pts (A, 53; B, 15; C, 18) received T-DXd. Median age was 58.5 y (range, 27-79), 53.5% were male, and 90.7% had left colon or rectum cancer. Median prior regimens for metastatic disease was 4 (range, 2-11). All pts had prior irinotecan; 30.2% in cohort A had prior anti-HER2 therapy. Median (m) treatment duration (all pts) was 3.0 mo (95% CI, 2.1-4.1; cohort A, 5.1 mo [95% CI, 3.9-7.6]). In cohort A (median FU, 62.4 weeks), confirmed ORR was 45.3% (24/53 pts; 95% CI, 31.6-59.6), DCR was 83.0% (44/53 pts; 95% CI, 70.2-91.9), mDOR was 7.0 mo (95% CI, 5.8-9.5), mPFS was 6.9 mo (95% CI, 4.1-8.7) with 37 (69.8%) PFS events, and mOS was 15.5 mo (95% CI, 8.8-20.8) with 36 (67.9%) OS events. These results are consistent with the primary analysis. Confirmed ORR was 43.8% (7/16 pts; 95% CI, 19.8-70.1) in pts with prior anti-HER2 therapy, 57.5% (23/40 pts; 95% CI, 40.9-73.0) in pts with IHC3+ status, and 7.7% (1/13 pts; 95% CI, 0.2-36.0) in pts with IHC2+/ISH+ status. In cohorts B and C, mPFS was 2.1 mo (95% CI, 1.4-4.1) and 1.4 mo (95% CI, 1.3-2.1); mOS was 7.3 mo (95% CI, 3.0-NE) and 7.7 mo (95% CI, 2.2-13.9), respectively. Treatment-emergent adverse events (TEAEs) of grade (G) ≥3 occurred in 65.1% of pts (56/86); the most common TEAEs were hematologic and gastrointestinal. TEAEs leading to drug discontinuation occurred in 13 pts (15.1%). 8 pts (9.3%) had interstitial lung disease (ILD) adjudicated by an independent committee as related to T-DXd (4 G2; 1 G3; 3 G5). Conclusions: T-DXd at 6.4 mg/kg Q3W showed promising activity and durability with longer-term FU in this pt population. The safety profile was consistent with prior results; ILD continues to be recognized as an important identified risk that requires careful monitoring and intervention as needed. These results support continued exploration of T-DXd in pts with HER2-overexpressing mCRC. Clinical trial information: NCT03384940.

PURPOSE BRAFV600 mutations are commonly found in melanoma and thyroid cancers and to a lesser degree in other tumor types. Subprotocol H (EAY131-H) of the NCI-MATCH platform trial sought to investigate the selective BRAF inhibitor dabrafenib and the MEK1/2 inhibitor trametinib in patients with solid tumors, lymphomas, or multiple myeloma whose tumors harbored a BRAFV600 mutation. PATIENTS AND METHODS EAY131-H is an open-label, single-arm study. Patients with melanoma, thyroid, or colorectal cancer were excluded; patients with non–small-cell lung cancer were later excluded in an amendment. Patients received dabrafenib 150 mg twice per day and trametinib 2 mg per day continuously until disease progression or intolerable toxicity. The primary end point was centrally assessed objective response rate (ORR); secondary end points included progression-free survival (PFS), 6-month PFS, and overall survival. RESULTS Thirty-five patients were enrolled, and 29 were included in the primary efficacy analysis as prespecified in the protocol. Median age was 59 years, and 45% of the patients had received ≥ 3 lines of therapy. The confirmed ORR was 38% (90% CI, 22.9% to 54.9%) with P < .0001 against a null rate of 5%, and PFS was 11.4 months (90% CI, 8.4 to 16.3 months); responses were seen in 7 distinct tumor types. Seven patients had a duration of response of > 12 months, including 4 patients with a duration of response of > 24 months. An additional 8 patients had a PFS > 6 months. The median overall survival was 28.6 months. Reported adverse events were comparable to those noted in previously reported profiles of dabrafenib and trametinib. CONCLUSION This study met its primary end point, with an ORR of 38% ( P < .0001) in this mixed histology, pretreated cohort. This promising activity warrants additional investigations in BRAFV600-mutated tumors outside of currently approved indications.

7502 Background: SELECT investigated whether the addition of C to standard chemotherapy improved progression-free survival (PFS) in patients (pts) with recurrent or progressive NSCLC after failure of platinum-based therapy. Methods: SELECT was a multicenter, open label, randomized phase III trial. Per investigator choice, pts received either P (500 mg/m2) or D (75 mg/m2) on day 1 and then were randomized within each group to chemotherapy plus C (400/250 mg/m2) (initial/weekly) or chemotherapy alone. Therapy was given for up to six 3-week cycles; pts randomized to C continued weekly monotherapy until disease progression or unacceptable toxicity. The primary objective was PFS for PC vs. P as determined by an Independent Review Committee (IRC). Secondary endpoints included overall survival (OS), objective response rate (ORR) and duration of response (DOR) by IRC, and safety. Preplanned subgroup analyses for epidermal growth factor receptor (EGFR) staining intensity by immunohistochemistry and histology were performed. Results for PC vs. P only are presented. Results: Between Jan 2005 and Feb 2010, 938 total pts were randomized. Baseline demographics were comparable between PC (n=301) and P (n=304): median age 64 years; male 60%; Caucasian 88%; KPS 80-100/60-70 84%/16%; squamous/non-squamous 24%/76%. Median PFS (months) PC: 2.89 and P: 2.76 (hazard ratio [HR] =1.03 [95% confidence interval (CI)=0.87-1.21]; p=0.76). Median OS (months) PC: 6.93 and P: 7.79 (HR=1.01 [95% CI=0.86-1.20]; p=0.86). ORR PC: 6.6% and P: 4.3% (odds ratio =1.59 [95% CI=0.78-3.26]; p=0.20). Median DOR (months) PC: 4.17 and P: 6.93 (HR=1.58 [95% CI=0.74-3.36]; p=0.24). There were no statistical differences in efficacy based on histology or EGFR staining intensity. More drug-related AEs/SAEs were observed in the PC arm, with differences mainly attributable to skin toxicities, GI (diarrhea/stomatitis), and hypomagnesemia. Conclusions: The addition of C to P did not improve efficacy in this pt population. Further biomarker analyses are planned. The safety profiles for C and P were consistent with existing data and no new safety signals were observed.

TPS8112 Background: MM remains incurable and patients (pts) typically relapse or become refractory to current treatments. Novel regimens are needed to improve pt outcomes. Elo is a humanized monoclonal IgG1 antibody targeting the cell surface glycoprotein CS1, which is highly expressed on >95% of MM cells. Len/Dex is approved for treatment of relapsed MM and an objective response rate (ORR) of ~60% was reported in phase III trials of this combination in RR MM. In a phase II study (N=73) of Elo (10 or 20 mg/kg) in combination with Len/Dex in pts with RR MM, the 10 mg/kg group (n=36) demonstrated an ORR of 92% and median progression-free survival (PFS) that was not reached after a median follow-up of 14.1 months. Encouraging activity was seen in patients with high-risk cytogenetics and/or stage 2-3 disease. Based on these data, a randomized, open-label phase III trial has been initiated to determine if the addition of Elo to Len/Dex will improve PFS in patients with RR MM compared with Len/Dex alone. Methods: Pts (N=640) with RR MM and 1-3 prior therapies are eligible, including pts with mild or moderate renal impairment. Pts are randomized in a 1:1 ratio to receive 28-day cycles of Len 25 mg PO (days 1-21) and Dex 40 mg PO (days 1, 8, 15 and 22) with or without Elo. Elo dose and schedule is 10 mg/kg IV on days 1, 8, 15, 22 in the first 2 cycles and on days 1 and 15 in subsequent cycles. Dex 8 mg IV + 28 mg PO is used during the weeks with Elo. Treatment will continue until disease progression, death, or withdrawal of consent. Patients will be followed for tumor response every 4 weeks until progressive disease and then survival every 12 weeks. The primary endpoint is PFS (90% power for a hazard ratio [experimental to control arm] of 0.74) and the secondary endpoints are ORR and overall survival. Exploratory endpoints are safety, time to response, duration of response, time to subsequent therapy, health-related quality of life, and pharmacokinetics and immunogenicity of Elo. Potential biomarkers will also be assessed. As of January 10th, 2012, 107 pts were enrolled and 68 pts were treated. NCT01239797.

548 Background: YM155 (YM) is a small molecule survivin suppressant. In a phase I/II study of YM plus docetaxel (D) in solid tumors evidence of anti-tumor activity was observed in women with human epidermal growth factor 2 non-overexpressing (HER2 negative) metastatic breast cancer (mBC). Methods: This was a randomized study of YM plus D versus D as 1st line treatment in subjects with HER2 negative mBC. Eligibility criteria were: ECOG < 1, no prior chemotherapy for mBC, and at least one measurable lesion. Primary endpoint was progression free survival (PFS); secondary endpoints were: objective response rate (ORR), overall survival (OS), duration of response (DOR), clinical benefit rate (CBR), time to response (TTR) and safety. YM was administered at 5 mg/m2/day as a 168 hr continuous infusion followed by 14 Day (d) observation and D was administered at 75 mg/m2over 1 hr on d1 every 21d. In the control arm, D was dosed per investigator choice q 21d. Results: 101 subjects were randomized (50 YM + D; 51 D). Median (m) age 55 (range: 25 – 79), 25% had triple negative disease, > 60% had bone and lymph mets, 86% had prior therapy for BC. mPFS (days) was 251 (95%CI: 176 – 333) YM + D vs 252 (95%CI: 202-433) D (p=0.34). ORR, CBR and TTR (YM+D; D): 26% vs. 25.5%; 82% vs. 84.3% and 45 vs 59 d. OS data are immature but showed no difference (p=0.911). Adverse events [AEs (> 25%)] [YM + D% vs D %]: neutropenia 83 vs 84, alopecia 62.5 vs 53, fatigue 50 vs 41.2, nausea 35.4 vs 41.2, leucopenia 27 vs 33 and dyspnoea 33 vs 14. Common (>10%) serious AEs [YM + D% vs D%]: febrile neutropenia 21 vs 8 and neutropenia 10 vs 8. Conclusions: Preclinical and clinical evidence suggested the combination of YM + D may offer additional benefit to D alone in subjects with mBC. This study showed no difference in efficacy, but the combination appeared to be well tolerated. Clinical trial information: NCT01038804.

4525 Background: Anti-PD-L1 immunotherapy shows promising clinical activity in UC. We report a planned update of the safety and efficacy of durvalumab in patients (pts) with locally advanced/metastatic UC from a multicenter, phase 1/2 open-label study. Methods: Pts received durvalumab 10 mg/kg every 2 weeks (Q2W) up to 12 months (mo) or until unacceptable toxicity, progression, or starting another anticancer therapy. Primary endpoints were safety and confirmed objective response rate (ORR) by blinded independent central review (RECIST v1.1). Duration of response (DoR), progression-free survival (PFS) and overall survival (OS) were key secondary endpoints. Tumor PD-L1 expression was assessed by Ventana SP263 assay (PD-L1 high = ≥25% PD-L1 expression on tumor or immune cells). Results: As of Oct 24, 2016 (data cutoff [DCO]), 191 pts had received treatment. Median follow-up was 5.78 mo (range, 0.4–25.9). All pts had Stage 4 disease and 99.5% had prior anticancer therapy (95.3% post-platinum). As of DCO, ORR was 17.8% (34/191), including 7 CRs, with responses observed regardless of PD-L1 status (Table). Responses occurred early (median time to response, 1.41 mo) and were durable (median DoR not reached [NR]). Median PFS and OS were 1.5 mo (95% CI, 1.4, 1.9) and 18.2 mo (95% CI, 8.1, not estimable [NE]), respectively; the 1-year OS rate was 55.0% (95% CI, 43.9%, 64.7%). Grade 3/4 treatment-related AEs occurred in 6.8% of pts; grade 3/4 immune-mediated (im)AEs occurred in 4 pts; 2 pts discontinued due to imAEs (acute kidney injury and autoimmune hepatitis). Conclusions: Durvalumab 10 mg/kg Q2W shows favorable clinical activity and an excellent safety profile in locally advanced/metastatic UC pts. Table.

9074 Background: BRAFV600 mutations occur in 1–2% of pts with NSCLC. We previously reported the efficacy of vemurafenib, a selective BRAFV600 inhibitor, in BRAF mutation-positive non-melanoma tumors (VE-BASKET study). We now present final data for the expanded NSCLC cohort. Methods: This open-label, histology-independent, phase 2 study included 6 prespecified cohorts (including NSCLC) plus one ‘all-others’ cohort. Pts received vemurafenib (960 mg bid) until disease progression or unacceptable toxicity. The primary endpoint was objective response rate (RECIST v1.1). Secondary endpoints included best overall response rate, duration of response (DoR), progression-free survival (PFS), and overall survival (OS). Because the pre-specified clinical benefit endpoint was met in the initial NSCLC cohort, the cohort was expanded. ClinicalTrials.gov identifier NCT01524978. Results: Database lock was 12 Jan 2017. Of 208 pts enrolled at 25 centers worldwide, 62 pts had NSCLC: median age 65 years; 56% male; 13% had no prior systemic therapy; 50% had ≥2 prior therapies. Responses were seen in previously treated and untreated pts (Table). The most common all-grade adverse event (AE) was nausea (40%); grade 3–5 AEs included keratoacanthoma (15%) and squamous cell carcinoma of the skin (15%). Six pts discontinued vemurafenib due to AEs; two had non-treatment-related fatal AEs. Conclusions: Vemurafenib showed evidence of encouraging efficacy in pts with NSCLC with BRAFV600 mutation, with prolonged PFS in previously untreated pts; median OS was not estimable due to ongoing responses. The safety profile of vemurafenib was similar to that seen in melanoma studies. Our results suggest a role for BRAF inhibition in NSCLC with BRAF mutations. Clinical trial information: NCT01524978.
