9574 Background: Prior data from a phase I/II study showed durable responses, including efficacy in brain lesions, and a tolerable safety profile with nazartinib in treatment (tx)-naïve patients (pts) with EGFR-mutant (mut), locally advanced (adv)/metastatic NSCLC. Here we report updated phase II results, including overall survival (OS). Methods: Tx-naïve adult pts with activating EGFR-mut (L858R or ex19del), stage IIIB/IV adv NSCLC with neurologically stable and controlled brain metastasis (BM) received oral nazartinib 150 mg once daily (continuous schedule). Primary endpoint: overall response rate (ORR) by BIRC per RECIST v1.1; secondary endpoints: disease control rate (DCR), duration of response (DOR), time to response, progression-free survival (PFS), OS, and safety. Results: At data cut-off (Nov 1, 2019), 45 pts were enrolled (median [range] age: 64 [28–83] years; 26 pts [58%] ECOG PS 1; 18 pts [40%] had baseline BM). EGFR mutations: 56% ex19del, 40% L858R, 4% other. 26/45 pts (58%) discontinued tx, with the primary reason being progressive disease in 19 pts (42%); 2 pts (4%) discontinued tx due to AEs. Median (range) follow-up for OS: 25 (0–33) months (mo); and for PFS: 17 (0–33) mo. ORR by BIRC: 69%; median PFS by BIRC: 18 mo; median OS was NE and at 33 mo, 56% of pts were alive (Table). BIRC results by baseline BM are shown in the Table. Median (range) duration of exposure: 24 (0–34) mo. Most frequent AEs (≥20% all grade, all causality): diarrhea (47%), maculopapular rash (38%), pyrexia (29%), cough and stomatitis (27% each), decreased appetite and pruritus (24% each), and dermatitis acneiform (22%). Most frequent grade 3/4 AEs (≥10%, all causality): maculopapular rash (5 pts [11%]; all grade 3) and increased lipase (5 pts [11%]; 1 pt with grade 4; no clinical pancreatitis AE was observed). Conclusions: After additional follow-up, median OS was still not reached and the safety profile was manageable. Nazartinib is a promising 3rd generation EGFR TKI for tx-naïve pts with adv EGFR-mut NSCLC, including pts with baseline BM. Clinical trial information: NCT02108964 . [Table: see text]

Abstract Background: The activity of V in myeloma was first described in the 1970’s. Although Phase II data suggest that V demonstrates single agent activity, subsequent reports have questioned its role. Due to these conflicting results, we conducted a subanalysis investigating the effect of V dose in the phase II DVd-T regimen that we have previously reported (Agrawal et al ASH 2003). We evaluated the effects of V dose on progression free survival (PFS) and overall survival (OS) in newly diagnosed and relapsed/refractory patients treated with DVd-T. Patients and Methods: As previously reported, this Phase II study enrolled 102 patients with newly diagnosed or relapsed/refractory multiple myeloma with evidence of end organ damage. DVd-T was administered as previously reported. After best response, patients were maintained on prednisone 50mg every other day and the maximum tolerated dose of thalidomide until disease progression. For patients experiencing grade 1 neuropathy, V was reduced by 25%, and for grade 2, by 50%. Patients developing grade 3/4 neuropathy had V discontinued and thalidomide suspended until toxicity decreased by at least one grade. Univariate analyses were conducted to assess the effect of V dose reduction or elimination on PFS and OS. Multivariate analyses were performed to adjust for the impact of age, platelet count, stage, quality of response (CR or near CR versus SD or PR), and thalidomide dose. Results: Trial included 53 newly diagnosed and 49 relapsed/refractory patients. Median age was 62.9 years. 59% had stage 3 or 4 disease. 37% had abnormal cytogenetics. Median beta-2 microglobulin was 4.1. Overall response rate of 87% was seen in newly diagnosed patients (36% achieved CR; 13% near CR; 38% PR; 8% SD; 6% PD). In the relapsed/refractory patients, overall response rate of 87% was achieved (21% achieved CR; 26% near CR; 40% PR; 13% SD). Median follow up was 28.1 months. Median PFS for the newly diagnosed group was 28.2 months and 15.5 for the relapsed/refractory group. Median OS was 39.9 months for the relapsed/refractory group. After 50 months of follow-up for the newly diagnosed group, median OS has not been reached. In total, 464 cycles were administered, of which 225 were given with full dose V and 242 with reduced dose or eliminated V. Grade 3/4 neuropathy occurred in 22 patients. Univariate analysis revealed that reducing or eliminating V had a significant positive effect on PFS and OS (p = 0.0002 and 0.02 respectively). Multivariate analysis adjusting for age at start of study, platelet count, stage, quality of response [CR or near CR versus SD or PR], and thalidomide dose, similarly found that reducing or eliminating the dose of V had a significant positive effect (p = 0.0121) on PFS. However, multivariate analysis did not reveal the same effect on OS (p = 0.11). Conclusions: This subanalysis suggests that the use of full dose V in the DVd-T regimen may have a negative effect on PFS. The exact mechanism by which V affects PFS is not clear. Studies are now on-going investigating this regimen without V. Figure Figure

4554 Background: Combination regimens of 3 drugs have shown promising activity as treatment for patients (pts) with metastatic gastric cancer (GC). Docetaxel combined with cisplatin and 5-FU (CF) improved overall survival and response rates when compared to standard CF. However, the identification of less toxic and more convenient variants of this regimen is still important. We have previously established a regimen with docetaxel (T) combined with oxaliplatin (E) and capecitabine (X) in a phase I trial [Grothe et al., Proc. ASCO 2006]. Results of a preplanned interim analysis of subsequent multicenter phase II trials of the TEX regimen are presented here. Methods: Pts with metastatic or locally advanced GC, adequate organ function, ECOG PS 0–2, and no prior chemotherapy for advanced disease (adjuvant allowed) were enrolled. TEX regimen was administered as defined: T 35 mg/m2 and E 70 mg/m2 on days (d) 1 and 8, with X 800 mg/m2 bid on d1–14 every 22 days Toxicity assessment was done 3-weekly while CT scans were repeated 9-weekly. Results: 35 of 48 pts were enrolled until 06/08: 28 male / 7 female, median age 59 (36–81) years, ECOG PS 0/1/2 69%/31%/0%, gastric / gastroesophageal cancer 60%/40%, distant metastases 96%, tumor in situ 37%. The most common toxicities reported were (CTC grade [gr] 3/4): diarrhea 20%/3%, vomiting 11%/3%, asthenia and neurotoxicity each 9%/0%. Mucositis and hand-foot-syndrome were observed in (grade 1+2 / grade 3) 29%/0% and 26%/3%, respectively. Hematoxicity was mild with grade 3 anemia in 10% and no other grade 3/4 toxicity except one episode of febrile neutropenia . Of 25 pts evaluable so far, first tumor response assessment revealed (RECIST criteria) partial response in 36% and stable disease in 40% of patients. Conclusions: TEX is a safe and tolerable regimen for patients with metastatic gastric cancer. Preliminary efficacy results indicate promising activity. Mature data including progression free survival will be presented at the meeting. [Table: see text]

3575 Background: The literature reports that adding biologics to chemotherapy (ctx) may increase the incidence of clinically significant neutropenia. his trial was conducted to evaluate the efficacy of PEG in reducing the incidence of febrile neutropenia (FN) in pts with locally-advanced (LA) or metastatic (m)CRC receiving first-line treatment with either FOLFOX/B or FOLFIRI/B. Methods: Key eligibility: ≥ 18 years old; measurable, nonresectable CRC per RECIST 1.1. Pts were randomly assigned 1:1 to either placebo or 6 mg PEG ~24 h after ctx/B. The study treatment period included four Q2W cycles, but pts could continue their assigned regimen until progression. Pts were stratified by region (North America vs rest of world), stage (LA vs mCRC), and ctx (FOLFOX vs FOLFIRI). Estimated sample size (N = 800) was based on the expected incidence of grade 3/4 FN (primary endpoint) across the first 4 cycles of ctx/B, powered for PEG superiority over placebo. Other endpoints included overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). Results: 845 pts were randomized (Nov 2009 to Jan 2012) and received study treatment; 783 pts completed 4 cycles of ctx/B. Median age was 61 years; 512 (61%) pts were male; 819 (97%) had mCRC; 414 (49%) received FOLFOX, and 431 (51%) received FOLFIRI. Grade 3/4 FN (first 4 cycles) for placebo vs PEG was 5.7% vs 2.4%; OR 0.41; p = 0.014. A similar incidence of other ≥ grade 3 adverse events was seen in both arms (28% placebo; 27% PEG). See table for additional results. Conclusions: PEG significantly reduced the incidence of grade 3/4 FN in this pt population receiving standard ctx/B for CRC. Follow-up is ongoing. Clinical trial information: NCT00911170. [Table: see text]

9055 Background: LungMAP is a National Clinical Trials Network umbrella trial for previously-treated SqNSCLC. S1400D is a phase II biomarker-driven therapeutic sub-study evaluating the FGFR inhibitor AZD4547 in patients (pts) with FGFR positive chemo-refractory SqNSCLC. Methods: Eligible pts had tumor FGFR alteration and/or mutation by next generation sequencing (Foundation Medicine), measurable disease, Zubrod PS 0-2, progression after 1 line of systemic therapy, and adequate end organ function. Receipt of prior immunotherapy was allowed. Eligible pts received AZD4547 80 mg bid orally. Primary endpoint was overall response rate (ORR) by RECIST; secondary endpoints included progression-free survival (PFS) and duration of response (DoR). Originally designed as a randomized trial of AZD4547 versus docetaxel, it was redesigned to be a single arm AZD4547 trial with the emergence of immunotherapy as standard 2ndline therapy. Forty pts were required to rule out an ORR of < = 15% if the true ORR was > 35% (90% power, alpha 0.05). Results: 93 pts (13% of pts screened on S1400) were assigned to S1400D; 43 were enrolled with 28 receiving AZD4547. Pt characteristics: median age 66.3 y (49-88), female (n = 8, 29%), & Caucasian (n = 25; 89%). Biomarker profile: FGFR1 amplification (n = 38; 86%); FGFR3 S249C (n = 4; 9%); FGFR3 amplification (n = 3; 7%); and FGFR3 fusion (n = 2; 5%). Nine pts (26%) had more than one biomarker alteration. The study was closed at interim analysis for futility in October 2016. Treatment related Grade 3 AEs were seen in 5 pts (dyspnea, fatigue, hyponatremia, lung infection & retinopathy); 1 pt had Grade 4 sepsis. There were no Grade 5 AEs. Median follow up among alive pts was 4.3 months (mos). Of 25 response evaluable pts, one with FGFR3 S249C had unconfirmed PR (4%, 95% CI 1-20%) with DoR of 1.5 mos. Median PFS was 2.7 mos (95% CI 1.4 - 4.3 mos). Conclusions: This is the first Phase II trial to evaluate AZD4547 as a targeted approach in pts with previously treated FGFR-altered SqNSCLC. AZD4547 had an acceptable safety profile but minimal activity in this biomarker-enriched cohort. Evaluation of other targeted agents in LUNG-MAP is currently ongoing. Clinical trial information: NCT02965378.

e20618 Background: Osimertinib has been emerged as the standard selection in EGFR T790M-positive NSCLC patients who failed prior treatment with EGFR TKIs. However, acquired resistance to osimertinib is a growing clinical challenge. Despite the significant antitumor activity of Chemoimmunotherapy (CIT) combinations in NSCLC, clinical benefit in patients with EGFR mutations has not been shown obviously. Our objective was to assess the effectiveness and tolerability of CIT for metastatic EGFR-mutant NSCLC patients with acquired resistance to Osimertinib. Methods: We conducted a retrospective study in patients with sensitizing EGFR-mutant NSCLC who were resistant to Osimertinib and received anti-PD1 immunotherapy combined with chemotherapy at Chinese PLA General Hospital. Progression-free survival (PFS), overall survival (OS), overall response rate (ORR), and toxicities were examined. Results: Between Oct 2015 and Nov 2018, 11 patients were available for analysis, 45.5% male, 45.5% ECOG PS 0-1, median age 54 years, all pts who failed treatment with Osimertinib had received previously targeted therapies. In this CIT combination group, 6 [54.5%] of 11 pts received pembrolizumab and 5[54.5%] of 11 pts received Nivolumab anti-PD1 therapy, 8 [72.7%] of 11 pts received mono-chemotherapy and 3 [27.3%] of 11 pts received platinum-based doublet chemotherapy. The median PFS was 7.47 months (95% CI 3.04 to 11.89). Despite Median OS was not reached, the OS rate at one year was 6 [54.5%] of 11. The ORR was 5 [45.5%] of 11. Treatment-related adverse events (TRAE) of grade 3 or higher were reported in 6 [54.5%] of 11 patients. The most common grade 3 or worse TRAEs were fatigue (3 [27.3%] of 11) and anemia (3 [27.3%] of 11); The following ≥Grade 3 TRAEs occurred once: decreased neutrophil count, acute kidney injury, gastrointestinal bleeding. One patient discontinued treatment because of immune-associated gastroenteritis. Conclusions: In metastatic NSCLC patients with activating EGFR mutation resistant to Osimertinib, our single institution real-world experience in Chemoimmunotherapy combination shows promising activity and acceptable toxicity profile. Given the small number of patients studied, further clinical trials are warranted.

9503 Background: The immunomodulatory receptor TIGIT is a novel inhibitory immune checkpoint present on activated T cells and NK cells in multiple cancers, including NSCLC. In a phase I study (GO30103), co-inhibition of TIGIT and PD-L1 signaling with tira plus atezo in CIT-naïve PD-L1 positive NSCLC potentially improved overall response rates (ORR) compared to historical ORR with PD-L1/PD-1 inhibitors. We conducted this phase II trial to confirm the efficacy and safety of tira plus atezo (TA) compared to placebo plus atezo (PA) in 1L NSCLC (GO40290, NCT NCT03563716). Methods: This prospective, randomized, double-blind, placebo-controlled trial enrolled patients (pts) with chemotherapy-naïve PD-L1+ (TPS ≥ 1% by 22C3 IHC pharmDx Dako assay) locally advanced or metastatic NSCLC with measurable disease, ECOG PS 0-1, and without EGFR or ALK alterations. Pts were randomized 1:1 to TA (tira 600 mg IV plus atezo 1200 mg IV) or PA (placebo plus atezo 1200 mg IV) on day 1 of every 3-week cycle. Stratification factors were PD-L1 status (TPS ≥ 50% vs TPS 1-49%), histology, and tobacco history. Co-primary endpoints were investigator assessed ORR and PFS, and additional endpoints were duration of response (DOR), OS, and safety. Exploratory endpoints were the effect of PD-L1 status on ORR and PFS. Results: 135 pts were randomized to PA (n = 68) or TA (n = 67). At primary analysis (30 Jun 2019), TA improved ORR and median PFS (mPFS) compared to PA, with median follow-up of 5.9 mo. In the safety population (68 in PA, 67 in TA), treatment-related AEs (TRAEs) occurred in 72% (PA) and 80.6% (TA); Grade ≥3 TRAEs occurred in 19.1% (PA) and 14.9% (TA). AEs leading to treatment withdrawal occurred in 10.3% (PA) and 7.5% (TA). Clinical trial information: NCT03563716 . With an additional six months of follow-up since the primary analysis (2 Dec 2019, median follow-up of 10.9 mo), improvement in ORR and mPFS was maintained in ITT for TA (37.3% [25.0, 49.6] and 5.6 mo [4.2, 10.4]) vs PA (20.6% [10.2, 30.9] and 3.9 mo [2.7, 4.5]). The safety profile remained tolerable. Conclusions: Treatment with TA compared to PA showed clinically meaningful improvement in ORR and PFS in ITT. The safety profile of TA was similar to PA.

619 Background: There is a strong rationale for investigating MET and PD-L1 inhibition in metastatic papillary renal cancer (PRC). We previously reported response rates (RR) and progression free survival (PFS) for savolitinib (MET inhibitor) and durvalumab (PD-L1 inhibitor) together. Here we report overall survival (OS) data available 12 months after the last patient was enrolled. Methods: This single arm phase I/II trial explores durvalumab (1500mg Q4W) and savolitinib (600mg OD) together in PRC, with a 4wk savolitinib run in. Treatment naïve or previously treated patients with metastatic PRC were included. Confirmed RR (RECIST v1.1), PFS, tolerability (CTCAE v4.03) and overall survival (OS) were analysed. MET and PD-L1 biomarkers were explored (NCT02819596). Results: 42 patients were enrolled with 41 receiving at least one dose of study treatment. Safety and efficacy analyses were performed on these 41 patients. The median follow up was 14.3 months. IMDC good, intermediate and poor risk disease occurred in 29%, 63%, and 7% of patients respectively. Overall confirmed RR was 27% while median PFS was 4.9 months (95% CI: 2.5 – 12.0 months). Median OS was 12.3 months (95% CI: 5.8 – 21.3 months). Confirmed RR and median OS in the previously untreated cohort (N=27) were 33% and 12.3 months (95% CI: 4.7 – not reached (NR) months) respectively. Treatment related Grade 3/4 toxicity occurred in 34% of patients. No new safety signals were seen. PD-L1 and MET expression were not associated with higher RR (25% and 40% respectively) or longer OS. Conclusions: The combination of savolitinib and durvalumab has clinical activity in PRC and outcomes were not enhanced in biomarker positive cancers. Clinical trial information: NCT02819596.

489 Background: Aberrant activation of fibroblast growth receptor (FGFR) signaling plays a role in UC. Rogaratinib, a pan-FGFR1-4 inhibitor, has promising efficacy and safety in pts with advanced muscle-invasive UC, selected based on FGFR1-3 mRNA overexpression and/or FGFR3-activating mutations/translocations. This Phase II/III, randomized, open-label study evaluated the efficacy of rogaratinib vs CT in pts with FGFR-positive advanced or metastatic UC who received prior platinum CT. We present an ORR analysis for rogaratinib vs CT. Methods: FGFR1/3 mRNA was tested by in situ hybridization of archival tissue. Pts were randomized 1:1 to 800 mg rogaratinib p.o. BID continuously or CT Q3W (i.v., docetaxel 75 mg/m2, paclitaxel 175 mg/m2, or vinflunine 320 mg/m2), and stratified by PIK3CA/ RAS-activating mutations, prior immunotherapy, and modified 4-factor Bellmunt risk score. Results: 87 pts were assigned to rogaratinib and 88 to CT. Overall, 82.9% were male, median age was 69.0 yrs (range: 36-89), 96.6% had stage IV disease, and 2.3% were stage IIIB. PIK3CA/ RAS-activating mutations were present in 11.4% of pts. ORRs of 19.5% and 19.3% (1-sided p=0.56) and disease control rates of 49.4% and 55.7% (p=0.84) were observed for rogaratinib and CT, respectively; median progression-free survival was 2.7 months (95% CI 1.6, 4.2) and 2.9 months (95% CI 2.6, 4.2). Grade 3-4 treatment-emergent adverse events occurred in 40/86 pts (47%) treated with rogaratinib and 46/82 pts (56%) with CT, most commonly anemia (3% vs 15%), neutropenia (1% vs 17%), asthenia (9% vs 1%), lipase increase (8% vs 2%), fatigue (2% vs 6%), and urinary tract infection (2% vs 6%). Exploratory analysis of pts with FGFR3 DNA alterations (4 spot mutations and fusions) showed ORRs of 52.4% with rogaratinib and 26.7% with CT. Conclusions: In pts with FGFR1/3 tumor mRNA-positive UC, rogaratinib had efficacy comparable with standard CT and an acceptable safety profile. Subgroup analysis suggests rogaratinib may be more active in pts with an FGFR3 DNA alteration. Sensitivity analysis of biomarker subgroups is ongoing. Clinical trial information: NCT03410693.

7045 Background: We previously reported efficacy and safety of cisplatin-docetaxel and concurrent thoracic radiotherapy (TRT) for LA-NSCLC (Segawa Y and Kiura K. JCO 2010). However, its cure rate remains unsatisfied, and further improvement in the treatment outcome is strongly warranted. Recently, systemic chemotherapy has been individualized by intensive anti-cancer researches through the discovery of certain molecular targets in the metastatic NSCLC. Especially, gefitinib, EGFR tyrosine kinase inhibitor, is quite active and now one of the standard chemotherapy for untreated metastatic EGFR-mutant NSCLC (Maemondo M and Inoue A. NEJM 2010). Even in the locally advanced setting, approximately 30% of Japanese NSCLC patients possess EGFR-mutant tumors. Given all of these backgrounds, investigation on the role of adding gefitinib monotherapy to the standard concurrent chemoradiotherapy might cause a new paradigm shift in this setting. Methods: Patients have to meet the following eligibility criteria: LA-NSCLC; active tumor EGFR mutations (exons 19 and 21) but without 790M; measurable lesions; performance status (PS) of 0 or 1; age < 75 years; and V20 ≤ 35%. The primary endpoint is set as 2-year progression-free survival (PFS) rate; assuming that 75% in eligible patients would indicate potential usefulness, whereas 60% would be the lower limit of interest (α = 0.05, ß = 0.20), the estimated accrual number is 46 patients. The secondary endpoint includes toxicity, response rate and overall survival. Patients will receive the induction treatment, specified as gefitinib monotherapy (250 mg/body) for 8 weeks. Patients who have not progressed during the induction therapy will receive cisplatin and docetaxel (40 mg/m2; days 1, 8, 29, 36, each) and concurrent three-dimensional conformal TRT (2-Gy, single, daily fractions for 5 consecutive days each week to provide a total dose of 60 Gy). Enrollment began in 2010, and will complete by 2015. UMIN registration number of 000005086.

LBA445 Background: The literature reports that adding biologics to chemotherapy (ctx) may increase the incidence of clinically significant neutropenia. This trial was conducted to evaluate the efficacy of PEG in reducing the incidence of febrile neutropenia (FN) in pts with locally advanced (LA) or metastatic (m)CRC receiving first-line treatment with either FOLFOX/B or FOLFIRI/B. Methods: Key eligibility: ≥ 18 years old; measurable, nonresectable CRC per RECIST 1.1. Pts were randomly assigned 1:1 to either placebo or 6 mg PEG ~24 h after ctx/B. The study treatment period included four Q2W cycles, but pts could continue their assigned regimen until progression. Pts were stratified by region (North America vs rest of world), stage (LA vs mCRC), and ctx (FOLFOX vs FOLFIRI). Estimated sample size (N = 800) was based on the expected incidence of grade 3/4 FN (primary endpoint) across the first 4 cycles of ctx/B, powered for PEG superiority over placebo. Other endpoints included overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). Results: 845 pts were randomized (Nov 2009 to Jan 2012) and received study treatment; 783 pts completed 4 cycles of ctx/B. Median age was 61 years; 512 (61%) pts were male; 819 (97%) had mCRC; 414 (49%) received FOLFOX, and 431 (51%) received FOLFIRI. Grade 3/4 FN (first 4 cycles) for placebo vs PEG was 5.7% vs 2.4%; OR 0.41; p = 0.014. A similar incidence of other ≥ grade 3 adverse events was seen in both arms (28% placebo; 27% PEG). See Table for additional results. Conclusions: PEG significantly reduced the incidence of grade 3/4 FN in this pt population receiving standard ctx/B for CRC. Follow-up is ongoing. Clinical trial information: NCT00911170. [Table: see text]
