128 Background: Targeting multiple immune checkpoint pathways and combining checkpoint inhibition with chemotherapy may enhance response in MSS-CRC. In a Phase 1/2, multicenter, open-label study, the anti-PD-L1 antibody durvalumab (D) was added to monalizumab (M; an anti-NKG2A antibody). In dose-exploration cohorts, D+M was added to chemotherapy and a biologic agent (bevacizumab [DMCB] or cetuximab [DMCC]) for first-line treatment of advanced/metastatic MSS-CRC. Initial data showed DMCB was well tolerated and clinically active. Here we report updated efficacy and safety of DMCB and initial safety of DMCC. Methods: Eligible patients (pts) had MSS-CRC ( RAS/BRAF wt with a left-sided colon primary tumor in the DMCC cohort) and ECOG PS 0–1. They received D 1500 mg Q4W, M 750 mg Q2W, mFOLFOX6 Q2W and bevacizumab 5 mg/kg Q2W or cetuximab 250/400 mg/m2 QW (up to 500 mg/m2 Q2W) for up to 3 yr. The primary endpoint was safety and tolerability; secondary endpoints included antitumor activity. Results: As of Aug 26, 2019, 18 pts received DMCB and 17 pts received DMCC. Treatment-emergent adverse events (AEs) occurred in 100.0% of the DMCB cohort (most commonly fatigue, nausea and peripheral neuropathy) and 94.1% of the DMCC cohort (most commonly peripheral neuropathy, rash and dermatitis acneiform). The AEs were grade 3/4 in 77.8% of pts receiving DMCB and 70.6% of pts receiving DMCC, and were serious in 38.9% and 47.1%, respectively. Response was evaluable in 17 pts receiving DMCB; objective response rate was 41.2% (all PRs; Table). Responses occurred early and the median duration of response has not yet been reached. Conclusions: In advanced/metastatic MSS-CRC, first-line DMCB and DMCC had a manageable safety profile and DMCB showed promising preliminary activity. Clinical trial information: NCT02671435.

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.

1040 Background: The randomized phase III TURANDOT trial compared first-line BEV plus paclitaxel (PAC) vs BEV plus capecitabine (CAP) in HER2-negative metastatic BC (mBC). BEV-based regimens are often favored in TNBC [Dawood 2012] because of efficacy in subgroup analyses and a lack of effective treatments. We performed an exploratory subgroup analysis of TURANDOT to provide more data on BEV-based therapy in TNBC. Methods: Patients (pts) with HER2-negative mBC who had received no prior chemotherapy for mBC were randomized to either BEV–PAC (BEV 10 mg/kg d1 and 15 + PAC 90 mg/m2 d1, 8, and 15 q4w) or BEV–CAP (BEV 15 mg/kg d1 + CAP 1000 mg/m2bid d1–14 q3w). The primary endpoint was overall survival (OS); secondary endpoints included objective response rate (ORR), progression-free survival (PFS), and safety. Results: Of 561 pts treated, 130 had TNBC. Baseline characteristics were typical of a poor-prognosis population and generally balanced between treatment arms, although fewer pts receiving BEV–PAC than BEV–CAP had ECOG PS 1/2 (25% vs 40%, respectively), positive lymph nodes (56% vs 72%), metastatic disease at first diagnosis (19% vs 30%), and liver metastases (27% vs 43%). Median age was 54 vs 56 years, respectively. At data cut-off, median follow-up was 21.4 vs 19.2 mo for BEV–PAC and BEV–CAP, respectively. The safety profiles in the TNBC subgroup were similar to the overall population. The predominant grade ≥3 AEs were hematologic AEs and neuropathy with BEV–PAC and hand-foot syndrome and diarrhea with BEV–CAP. Conclusions: One-year OS rates up to 78% in TURANDOT are among the highest seen in TNBC. BEV-based therapy is a valid option in a setting with limited active treatments. BEV–PAC may be favored based on 1-year OS, PFS, and ORR. Clinical trial information: NCT00600340. [Table: see text]

11565 Background: TAPUR is a phase II basket study evaluating anti-tumor activity of commercially available targeted agents in pts with advanced cancers with genomic alterations. Results in a cohort of STS pts with CDK4 amplification treated with P are reported. Methods: Eligible pts had advanced STS, no standard treatment options, measurable disease, ECOG PS 0-2, and adequate organ function. Genomic testing was performed in CLIA-certified, CAP-accredited site selected labs. Pts received P at 125 mg orally once daily for 21 days, followed by 7 days off until disease progression. Pts matched to P had CDK4 amplification and no RB mutations. Simon 2-stage design tested the null disease control (DC) - defined as partial (PR), complete response (CR) or stable disease at 16+ weeks (SD 16+) - rate of 15% vs. 35% (power = 0.85; α = 0.10). If ≥2 of 10 pts in stage 1 have DC, 18 more pts are enrolled. If ≥7 of 28 pts have DC, the null DC rate is rejected. Secondary endpoints are progression-free survival (PFS), overall survival (OS) and safety. Results: 29 pts (66% male) with STS with CDK4 amplification were enrolled from July 2016 to Nov 2019. 1 pt was not evaluable and excluded from efficacy analyses. Demographics and outcomes are summarized in Table. One pt with partial response (PR) and 12 pts with SD16+ were observed for DC and objective response (OR) rates of 48% (95% CI: 31%, 62%) and 3.7% (95% CI: 0.1%, 19%), respectively, and the null DC rate of 15% was rejected (p<0.001). 9/13 pts with DC continued on treatment for >32 weeks. 14 pts had at least one grade 3-4 AE at least possibly related to P with the most common being low WBC/platelets. Other grade 3 AEs included increased alanine aminotransferase, anemia, and fatigue. Conclusions: Monotherapy P demonstrated anti-tumor activity in heavily pre-treated pts with STS with CDK4 amplification. Additional study is warranted to confirm the efficacy of P in pts with STS with CDK4 amplification. Clinical trial information: NCT02693535. [Table: see text]

3559 Background: Cetuximab is an IgG monoclonal antibody targeting the EGFR showing to be effective both as single agent or in combination with Irinotecan (CPT-11) or Irinotecan/FU/FA in patients (pts) with EGFR-expressing metastatic colorectal cancer (CRC) in the first and second/subsequent-line setting. The current trial was designed to evaluate the efficacy and the safety of Cetuximab plus Folfox-4 as first -line treatment. The main objective was the percentage of confirmed objective response rate. Methods: Chemonaivepts with non-resectable metastatic CRC and expressing EGFR were treated with Cetuximab (400 mg/m2 week 1 and 250 mg/m2 weekly thereafter) plus Folfox-4 (every 2 weeks: Oxaliplatin 85 mg/m2, day 1; FA 100 mg/m2 2h, simultaneously with OH-P, and FU 400 mg/m2 iv bolus followed by 600 mg/m2 iv for 22h on days 1 and 2). The first evaluation of disease status (Recist criteria) was performed after the first 4 cycles and confirmed after one month. The treatment was continued until a maximum of 12 cycles of chemotherapy; the maintenaice with Cetuximab was permitted. Preliminary results: On the 65 screened pts, 47 (72%) had EGFR-expressing metastatic disease and were enrolled. Their main characteristics were: median Ecog PS 0; median age 66 yrs (range 43–74); main sites of disease: liver 31, lung 12, lymph-nodes 3, others 8. To date twenty-two pts are evaluable for activity and 27 for toxicity; 2 pts are not evaluable and 25 are too early. We observed 16 PR (72.7%), 5 NC (22.7%) and 1 PD (4.6%) for an ORR of 72.7% and a TGCR of 95.4%; the confirmed PR were 15 (68%). To date 2 pts undergone surgery of their metastases both for lung. The main adverse events grade 3/4 (NCI criteria) were: acne-like rush 18.5%, diarrea 7%, nausea/vomiting 4% and anemia 4%. Conclusions: Our preliminary results confirm that the combination of Cetuximab plus Folfox-4 has an high activity and a good safety profile in advanced CRC pts. The study is ongoing.

4094 Background: We have previously shown that capecitabine/irinotecan (XELIRI) is effective and well-tolerated in metastatic colorectal cancer (mCRC). Cetuximab, a monoclonal IgG1 antibody that binds to the extracellular domain of EGFR, is active in mCRC alone or in combination with chemotherapy. This study was designed to evaluate if cetuximab (Erbitux®) added to XELIRI improves outcome in first-line treatment of mCRC. Methods: Subjects had histologically confirmed colorectal adenocarcinoma with T4 lesions that were unresectable after preoperative chemoradiation therapy and/or metastases. The study regimen was capecitabine 1700 mg/m2 (850 mg/m2 PO BID Days 1–14), irinotecan 200 mg/m2 IV Day 1 every 3 weeks, and weekly cetuximab (initial dose 400 mg/m2 IV over 120 minutes, subsequent doses 250 mg/m2 over 30 minutes). Results: Between February and October 2005, 70 subjects enrolled. Baseline characteristics: 43 males (61%), median age 61.5 years, and ECOG PS 0/1= 66%/34%; 94% of subjects had adenocarcinoma. Prior therapy; surgery (91%), chemotherapy (20%), or radiotherapy (7%). Responses (pts >2 cycles) were; CR (4%), PR (36%), SD (40%) and PD (20%); 15 patients failed treatment; (n=4 allergic reaction, n=2 MD request, n=2 withdrew consent, n=2 Grade 4 neutropenia, and n=5 other AEs). The overall response rate was 40% and the disease control rate was 80%. Median duration of response was 8.8 months (range, 2.6–15.1) and median time to response was 2.0 months (range, 1.2–8.3). 64% of patients remain alive; of the 25 deaths, 84% were due to PD. No death was drug related. The most frequent Grade 3 and 4 treatment-related adverse events (AEs) included: diarrhea (25%), neutropenia (18%), nausea/vomiting (12%), rash and dehydration (9%, each), HFS and fatigue (7%), and allergic reaction (6%). 54% of patients required dose reductions. To date, 64 patients (91%) have gone off study, primarily due to PD (39%) or AE (33%); 3 patients remain on treatment. Conclusions: The combination of cetuximab and XELIRI is feasible and tolerable in first line mCRC. Toxicities are expected and manageable with dose reductions/delay.

5576 Background: Endometrial cancer (EC) is the most common gynecologic malignancy. Vascular endothelial growth factor (VEGF) overexpression in EC correlates with poor outcome, thus targeting VEGF is a rational therapeutic approach. We have conducted a two-stage open-label phase II study in advanced EC with sunitinib, an oral tyrosine kinase inhibitor of multiple VEGF receptors. Methods: Eligible pts have recurrent or metastatic EC and have received up to 1 prior chemotherapy (CT) regimen for metastatic disease. Sunitinib is given at 50 mg daily (OD) for 4 consecutive weeks (wks) followed by 2 wks off. Dose could be reduced to 37.5 mg OD and then 25 mg OD in the setting of toxicity. Imaging is repeated every 12 wks. Primary objectives are objective response rate (ORR by RECIST) and rate of 6-month progression-free survival (PFS). If 1 or more responses occur in the first 15 evaluable pts, the study would continue to a second stage (total = 30 pts). Secondary objectives are time to progression (TTP), overall survival (OS), and safety. Results: We report the results of the first stage of this study. Sixteen pts have been treated (median age: 63; range 41–74) with 37 cycles of sunitinib (median 2; range: 1–7). Baseline ECOG PS was 0 (7 pts), 1 (8 pts), or 2 (1 pt). Histology was endometrioid (7 pts), serous (5 pts), clear cell (1 pt), or mixed/other (3 pts). Most pts had high-grade histology (G3: 8; G2: 4; G1: 2; GX: 2). Nine pts had prior adjuvant CT, 8 pts had 1 prior CT for advanced EC, 4 pts had prior hormones and 7 pts had prior radiotherapy. Partial response was achieved by 2 pts (ORR = 12.5%), and 2 other pts had a best response of stable disease; 3 of these pts remained progression-free > 6 months. Median TTP = 2.5 months (95% CI: 2.47-NR), and median OS = 6.2 months (95% CI: 5.1-NR). Grade 3/4 adverse events (AE) in >10% of pts were fatigue (7 pts, 44%) and hypertension (5 pts, 31%). Dose reduction was required for 11 of 16 pts (69%). Two pts were inevaluable after receiving <2 cycles due to AE (grade 4 hyponatremia; grade 3 fatigue) and 1 other pt has yet to complete 2 cycles. Conclusions: Sunitinib shows preliminary activity in EC. This trial will proceed to a second stage of accrual to further explore the efficacy and safety of sunitinib in advanced EC.

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.

379 Background: This study aimed to assess the efficacy and tolerance of the combinationof chemotherapy and two targeted therapies as a first-line treatment in metastatic pancreatic cancer patients. Methods: We designed a phase 2 open-label, non-comparative, multicenter study (NCT01204372). Patients received weekly 1000 mg/m² gemcitabine (3 weeks out of 4), weekly trastuzumab (4 mg/kg the first week, 2 mg/kg afterwards) and erlotinib 100 mg/day per os. The primary endpoint was the disease control rate (DCR) according to RECIST. Using a Fleming’s single-stage procedure, the trial was considered positive if 29 patients had a controlled disease (out of 57 evaluable patients). Secondary endpoints included the safety, the progression-free survival (PFS) and the overall survival (OS). An ancillary study addressed the EGFR, HER2 and KRAS status of the patients. Results: Between June 2010 and July 2013, 62 patients were recruited (37 men). The median age was 62 years (range 35-77). Performance status was 0 (n=27) and 1 (n=35). 10 patients had had a surgery of the primary tumor (PT), of whom 6 had been treated with a gemcitabine-based adjuvant chemotherapy (> 6-month delay). PT were localized in the head (n=25), corpus (n=22) and tail (n=15) of pancreas. The number of metastatic sites varied from 1 (n=25) to ≥ 3 (n=15). The baseline median left ventricular ejection fraction was 65% (range 51-86%). All patients were evaluable for safety and 59 patients for efficacy. Main first cycle treatment-related toxicities included: grade 3 anorexia (27%), asthenia (13%), diarrhea (10%), anemia (6%), and thrombocytopenia (3%); grade 3-4 neutropenia (24%), and mucositis (6%); grade 2-3 cutaneous events (35%). No complete responses were observed. 11 patients had a partial response, 33 a stable disease and 15 a disease progression. Therefore, the DCR was 74.6% (95%CI: 61.6-85.0%). Definitive results for the secondary endpoints will be presented at the meeting. Conclusions: Our results showed that combining gemcitabine, trastuzumab and erlotinib is efficient in terms of DCR. A further study is necessary to investigate this promising association. Funding (Roche SAS). Clinical trial information: NCT01204372.

201 Background: TASQ is an oral immunomodulatory, antiangiogenic and antimetastatic agent that targets the tumor microenvironment. In a phase 2 trial in mCRPC, TASQ increased PFS in chemotherapy-naive pts vs placebo (PBO) (Pili et al. JCO 2011), but there was no OS benefit in a recent phase 3 trial (NCT01234311). This study assessed whether TASQ maintenance therapy improved disease control duration in mCRPC pts with response or stabilization on first-line docetaxel (NCT01732549). Methods: Pts with mCRPC not progressing after docetaxel (min. 6 cycles; RECIST criteria; no PSA rise for last 3 tests) were assigned (1:1) to receive within 6 wks of last docetaxel administration: oral TASQ qd (0.25 mg/d rising to 1.0 mg/d over 4 wks, if tolerated) or PBO, until progression or toxicity. Randomization was stratified by visceral metastases and opioid analgesic use. Primary endpoint: radiographic PFS (rPFS) per RECIST 1.1 and PCWG 2 criteria, assessed locally. Planned sample size: 140 pts to achieve 80% power to detect an rPFS hazard ratio (HR) of 0.588 with a 1-sided α error of 0.05. Secondary endpoints: other clinical outcome measures, OS and safety. Results: From Jan 2013 to Oct 2014, 144 pts were randomized (TASQ: n = 71; PBO: n = 73) at 44 sites in 11 countries. Baseline characteristics were similar in both groups – median age: 70 yrs; visceral metastases: 23%; ECOG PS 0–1: 97%; opioid use: 15%. Median follow up: 59 wks for TASQ; 53 wks for PBO. Median rPFS (locally assessed) was 31.7 wks [90% CI 24.3–53.7] with TASQ; 22.7 wks [90% CI 16.1–25.9] with PBO (HR 0.6 [90% CI 0.4–0.9]; p = 0.0162). OS data are immature (14 deaths). Median time to next anticancer therapy: 42.3 wks [90% CI 32.0–58.0] for TASQ; 29.0 wks [90% CI 23.1–39.1] for PBO (HR 0.7 [90% CI 0.5–1.0]). TEAEs ( ≥ Grade 3): TASQ (51%); PBO (26%). TEAEs with TASQ (all grades; > 20%): decreased appetite (37%), constipation (32%), fatigue (28%), nausea (27%), arthralgia (25%), asthenia (24%) and back pain (21%). Conclusions: We believe this is the first completed trial of a maintenance strategy with a novel agent in mCRPC, an appealing concept in pts not progressing after docetaxel therapy. Clinical trial information: NCT01732549.
