9000 Background: In the randomized phase 3 CheckMate 9LA trial (NCT03215706), first-line NIVO + IPI combined with 2 cycles of chemo significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) vs chemo alone (4 cycles). Clinical benefit was observed regardless of programmed death ligand 1 (PD-L1) expression level and histology. Here we report data with 2 years’ minimum follow-up from this study. Methods: Adult patients (pts) with stage IV / recurrent NSCLC, ECOG performance status ≤ 1, and no known sensitizing EGFR/ALK alterations were stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous) and were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles; n = 361) or chemo alone (4 cycles; n = 358). Pts with non-squamous NSCLC in the chemo-alone arm could receive pemetrexed maintenance. The primary endpoint was OS. Secondary endpoints included PFS and ORR by blinded independent central review, and efficacy by different PD-L1 levels. Safety was exploratory. Results: At a minimum follow-up of 24.4 months for OS (database lock: Feb 18, 2021), pts treated with NIVO + IPI + chemo continued to derive OS benefit vs chemo, with a median OS of 15.8 months vs 11.0 months, respectively (HR, 0.72 [95% CI, 0.61–0.86]); 2-year OS rates were 38% vs 26%. Median PFS with NIVO + IPI + chemo vs chemo was 6.7 months vs 5.3 months (HR, 0.67 [95% CI, 0.56–0.79]); 8% and 37% of pts who had disease progression received subsequent immunotherapy, respectively. ORR was 38% with NIVO + IPI + chemo vs 25% with chemo. Similar clinical benefit with NIVO + IPI + chemo vs chemo was observed in all randomized pts and across the majority of subgroups, including by PD-L1 expression level (Table) or histology. Any grade and grade 3–4 treatment-related adverse events were reported in 92% and 48% of pts in the NIVO + IPI + chemo arm vs 88% and 38% in the chemo arm, respectively. Conclusion: With 2 years’ minimum follow-up, first-line NIVO + IPI + chemo demonstrated durable survival and benefit versus chemo in pts with advanced NSCLC; no new safety signals were identified. Clinical trial information: NCT03215706. [Table: see text]

7565 Background: Standard first-line chemotherapy for elderly NSCLC pts has been considered as a monotherapy with vinorelbine or gemcitabine globally. However, we have demonstrated the high efficacy of CP for elderly pts in our previous trial (Ann Oncol 2010). Meanwhile, D has been considered as an alternative option for this population in Japan according to the result of WJTOG9904 (JCO 2006). Thus we compared the two regimens to select the proper candidate for future phase III trial. Methods: Eligible pts were aged 70 years or older with newly diagnosed stage IIIB/IV NSCLC; ECOG performance status 0-1; adequate organ function; written informed consent. Pts were randomized to receive carboplatin (AUC 6) on day 1 and paclitaxel (70mg/m2 on day 1, 8, and 15) every 4 weeks or D (60mg/m2 on day 1) every 3 weeks. The primary endpoint was overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival, and toxicity profile. Assuming that ORR of 40% would be potential usefulness while ORR of 20% would be the lower limit of interest, 40 pts in each arm were required if expect 10% loss to follow up. Results: Between July 2006 and September 2010, 84 pts were enrolled and 41 pts in CP arm and 42 pts in D arm were eligible (median age, 76 years; 75% male; 72% stage IV). Median treatment cycle was 4 in each arm (CP, range 1-6; D, range 1-8). ORRs were 51% (95%CI: 36-66%) and 26% (95%CI: 12-39%) in the CP and D arm, respectively. With a median follow-up of 18.4 months, median PFS were 6.5 and 3.9 months in the CP and D arm, respectively (Logrank, P=0.0027). Grade 3 or severer toxicities were as follows: neutropenia (CP, 56% and D, 79%), anemia (CP, 15% and D, 7%), thrombocytopenia (CP, 10% and D, 0%), infection (CP, 20% and D, 25%). One treatment-related death due to neutropenia, pneumonia, and lethal arrhythmia occurred in D arm but none in CP arm. Conclusions: The platinum doublet CP achieved higher activity with an acceptable toxicity profile for elderly pts with advanced NSCLC compared to monotherapy with D. The superiority of CP to the monotherapy in this trial is consistent with results of recent IFCT-0501 trial (Lancet 2011).

3521 Background: In the phase 2 CheckMate 142 trial, NIVO + low-dose IPI provided robust and durable clinical benefit and was well tolerated as 1L therapy for MSI-H/dMMR mCRC (Lenz et al. Ann Oncol 2018;29:LBA18). Longer follow-up data will be presented. Methods: Patients with MSI-H/dMMR mCRC and no prior treatment for metastatic disease received NIVO 3 mg/kg every 2 weeks + low-dose IPI 1 mg/kg every 6 weeks until disease progression or discontinuation. The primary endpoint was investigator-assessed objective response rate (ORR). Results: For all 45 patients (median follow-up was 13.8 months), ORR was 60% (95% CI 44.3–74.3). Responses were consistent with the overall population across subgroups including age, Eastern Cooperative Oncology Group (ECOG) performance status, prior adjuvant/neoadjuvant therapy, and mutation status (Table). Seven patients (16%) had grade 3–4 treatment-related adverse events (TRAEs); 3 (7%) had any grade TRAEs leading to discontinuation. Updated response, survival, and safety data after a longer follow-up (median 19.9 months) will be presented. Conclusions: NIVO + low-dose IPI demonstrated robust and durable clinical benefit and was well tolerated. Evaluated subgroups had responses consistent with the overall population. NIVO + low-dose IPI may represent a new 1L treatment option for patients with MSI-H/dMMR mCRC. Clinical trial information: NCT02060188. [Table: see text]

9501 Background: NIVO + IPI was shown to improve overall survival (OS) and durability of response vs chemo in 1L advanced NSCLC in CheckMate 227 Part 1, regardless of PD-L1 expression. We hypothesized that a limited course of chemo combined with NIVO + IPI could provide rapid disease control while building on the durable OS benefit seen with dual PD-1 and CTLA-4 inhibition. CheckMate 9LA (NCT03215706) is a phase 3 randomized study evaluating NIVO + IPI + 2 cycles chemo vs chemo in 1L stage IV/recurrent NSCLC. Methods: Adults with tx-naive, histologically confirmed stage IV/recurrent NSCLC, ECOG performance status 0–1, and no known sensitizing EGFR/ALK alterations were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles) (n = 361) or chemo (4 cycles) alone (n = 358), stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous). Chemo was based on histology. Pts with non-squamous NSCLC in the chemo-only arm could receive optional pemetrexed maintenance. Pts were treated with immunotherapy until disease progression, unacceptable toxicity, or for 2 y. The primary endpoint was OS; the interim analysis using Lan–DeMets alpha spending function with O’Brien–Fleming boundary was planned at ~80% information fraction (ie, after observing ~322 total events). Secondary endpoints included progression-free survival (PFS) and objective response rate (ORR) by blinded independent central review, and efficacy by PD-L1 subgroups. Exploratory endpoints included safety/tolerability. Results: Baseline characteristics were balanced across arms. At a preplanned interim analysis (minimum follow-up 8.1 mo), OS was significantly prolonged with NIVO + IPI + chemo vs chemo (HR 0.69, 96.71% CI: 0.55–0.87; P = 0.0006); statistically significant improvements in PFS and ORR were seen. With longer follow-up (minimum 12.7 mo), NIVO + IPI + chemo vs chemo continued to provide longer OS; median 15.6 vs 10.9 mo (HR 0.66, 95% CI: 0.55–0.80); 1-y OS rates were 63 vs 47%. Clinical benefit was consistent across all efficacy measures in key subgroups including by PD-L1 and histology. Grade 3–4 tx-related adverse events were reported in 47 vs 38% of pts in the NIVO + IPI + chemo vs chemo arms, respectively. Conclusions: CheckMate 9LA met its primary endpoint: a statistically significant improvement in OS was observed with NIVO + NSCLC-optimized IPI + a limited course of chemo vs chemo (4 cycles) in 1L advanced NSCLC. No new safety signals were reported. Clinical trial information: NCT03215706 .

7093 Background: Aim of this study was to evaluate the activity and toxicity of MTA and CBDCA combination as first line chemotherapy in advanced MPM. Methods: Chemonaive patients (pts) with histologically proven, an ECOG performance status (PS) 0–2, and measurable advanced MPM were considered. The schedule of administration was: pemetrexed 500 mg/m2 in combination with CBDA AUC 5, once every 21 days for 8 cycles. Results: From July 2003 to March 2005 76 pts (54 male and 22 female) have been treated with this combination chemotherapy. Median age was 62.7 years (range 40–70); median PS 0 (range 0–3); epithelial histologic findings were in 57 (75%), mixed in 13 (17.1%), sarcomatous in 3 (3.9%), and unspecified in 3 (3.9%) pts. A total of 537 cycles was administered (median 7, range 1 to 13). Grade 3 hematologic toxicity according to WHO criteria was seen in 43 (56.6%) pts (neutropenia in 30, thrombocytopenia in 8, and anemia in 5); grade 4 hematologic toxicity in 5 (6.6%) pts. The most common nonhematologic events were grade 3 nausea/vomiting in 10 (13.1%), and fever in 4 (5.3%) pts. 74 pts were evaluable for clinical response. There were 16 (21.%) partial responses (PR) and 3 (3.9%) complete responses (CR), for an overall response rate of 23.9%. 29 (38.2%) pts reported stable disease (SD). The overall survival was considered from date of diagnosis to date of death from any cause or to date of last follow-up. The median survival time for the entire group was estimated at 23 months. Conclusions: The results of this phase II study indicate that, at this dose and schedule, the combination of CBDCA and MTA is moderately active and that the profile of toxicity is acceptable in pts with advanced MPM. No significant financial relationships to disclose.

7554 Background: A prospective, nonrandomized, multicenter study was conducted to assess the effect of adding cet to pem and cis in pts with advanced nonsquamous NSCLC. Methods: 113 Caucasian performance status 0-1 pts received 1st line pem (500 mg/m2) and cis (75 mg/m2) on day 1 (21d cycle) for 4-6 cycles and cet (400 mg/m2 loading dose followed by 250 mg/m2) weekly. Non-progressive pts received pem 500 mg/m2 on day 1 (21d cycle) plus cet (250mg/m2 weekly) until progression. Pts received vitamin B12/folic acid and dexamethasone. Primary endpoint was objective response rate (ORR) (RECIST 1.0). Secondary endpoints were progression free survival (PFS), 1 year survival rate, translational research (TR) and safety. Results: Pts’ characteristics: median age 59.7 years, 64% male, 50% PS 0, 92% stage IV, and 78% adenocarcinoma. All pts completed ≥ 1 cycle of induction therapy and 45% and 43% completed ≥ 1 cycle of maintenance with pem and cet, respectively. ORR (n=109) was 38.5% (80% CI 32.2-45.1), all partial responses. Disease control rate (response/stable disease) was 59.6% (80% CI: 53.1-65.9). Median PFS was 5.82 months (80% CI: 4.40-6.70). One year survival rate was 0.45 (80% CI: 0.39-0.51). Significant associations were seen between high EGFR by IHC and increased PFS (cytoplasm: HR=0.46, p=0.035; membrane: HR=0.41, p=0.008), and between high nuclear TTF-1 and increased ORR (OR=7.73, p=0.021) / PFS (HR=0.21, p<0.001) / OS (HR=0.25, p=0.035). Of 113 pts evaluated for safety, 73 (64.6%) pts had drug related CTC Grade 3/4 adverse events (AE): most frequent were neutropenia (14.2%), rash (15%), and vomiting (8.8%). Drug related serious AEs were reported in 27.4% pts: most frequent were anemia (5.3%), neutropenia (5.3%), vomiting (3.5%), and rash, renal failure, diarrhea and fatigue (1.8% each). There were 2 potential on-study drug related deaths (sudden death and large intestinal perforation). Conclusions: Pem, cis and cet appeared efficacious and tolerable. These results support further evaluation in a randomized trial. The TR outcomes are hypothesis generating given the study’s size and nonrandomized nature.

e18005 Background: EOLE, a large cohort of 423 patients included in 1 year (July 2010 – July 2010) with locally advanced, metastatic or recurrent non-squamous NSCLC, aimed to describe the targeted population receiving first-line bevacizumab (Bev) in addition to chemotherapy with regards to progression-free survival, overall survival, safety and quality of life in real clinical practice. Methods: Patients who received physician’s choice of 1st-line Bev-containing treatment were included in this cohort study. Results: This analysis describes the inclusion data of 417 patients consisting of adenocarcinoma (92%), large cell carcinoma (4%), undifferentiated carcinoma in predominantly non-squamous (3%), bronchoalveolar carcinoma (1%). Patient characteristics were as follow: the median age being 60 (years) [32; 84], more males than females (68%), 40% had a baseline ECOG Performance Status (PS) 0, 47% of PS 1 and 12% of PS 2, most patients had Stage IV disease (91%), 13% of patients had never smoked. Tumor location was reported as central for 17% of patents and among them 4% was in contact with the large vessels. For 3% of the lesions a cavitation was notified; and 20% of included patients had brain metastases. The main comorbidities at the inclusion were: cardiovascular (45%), arterial thromboembolic and /or venous (20%) with pulmonary embolism (3%); related to the tumor lesion - bloody sputum (4%) and hemoptysis (1%). 68% of patients have received the dose of Bev 7.5mg/kg q3w; for 49% of patients Bev was combined with cisplatin/pemetrexed, 24% with carboplatin/paclitaxel, 13% with carboplatin/pemetrexed and 7% with cisplatin/gemcitabine. The EGFR mutation analysis was carried out for about 50% of patients. Conclusions: Compared to AVAil and SAil studies, EOLE cohort included more patients classified as having: a baseline PS of 2 (p <0.0001, Fisher test), a never smoked status (p<0.0001, chi2 test) and an adenocarcinoma (92%) (p<0.0001, chi2 test). Around a half of included patients received combination Bev - cisplatin /pemetrexed.

9504 Background: T-DXd is an antibody-drug conjugate composed of an anti-HER2 antibody, cleavable tetrapeptide-based linker, and topoisomerase I inhibitor payload. In a phase I trial, patients (pts) with HER2-mutated NSCLC who received T-DXd had a confirmed objective response rate (ORR) of 72.7% (8/11) (Tsurutani et al, WCLC 2018). DESTINY-Lung01 (NCT03505710) is an ongoing, multicenter, phase II study of T-DXd in pts with non-squamous NSCLC overexpressing HER2 or containing a HER2-activating mutation. We report data for the cohort with HER2 mutations after a median follow-up of 8.0 mo (range, 1.4-14.2 mo). Methods: Pts were treated with T-DXd 6.4 mg/kg every 3 weeks. The primary endpoint was confirmed ORR (complete response [CR] + partial response [PR]) by ICR. Additional endpoints were disease control rate (DCR; CR + PR + stable disease), duration of response (DOR), progression-free survival (PFS), and safety. Results: At data cutoff (25 Nov 2019), 42 pts (64.3% female) had received T-DXd. Median age was 63.0 years (range, 34-83 years; < 65 y, 59.5%); 45.2% had central nervous system metastases; ECOG performance status was 0 in 23.8% of pts and 1 in 76.2%. HER2 mutations were predominantly in the kinase domain (90.5%). Most pts (90.5%) had prior platinum-based chemotherapy and 54.8% had anti–PD-1 or –PD-L1 treatment; median number of prior treatment lines was 2 (range, 1-6). Median treatment duration was 7.75 mo (range, 0.7-14.3 mo); 45.2% of pts remained on treatment. Confirmed ORR by ICR among the 42 pts was 61.9% (95% CI, 45.6%-76.4%); median DOR was not reached at data cutoff; 16 of 26 responders remained on treatment at data cutoff; DCR was 90.5% (95% CI, 77.4%-97.3%); estimated median PFS was 14.0 mo (95% CI, 6.4-14.0 mo). All pts (42/42) had treatment-emergent adverse events (TEAEs); 64.3% were grade ≥ 3 (52.4% drug-related), including decreased neutrophil count (26.2%) and anemia (16.7%). There were 5 cases (11.9%) of drug-related interstitial lung disease (ILD) as adjudicated by an independent committee (all grade 2, no grade ≥ 3) and 1 case of grade 1 ILD is pending adjudication. TEAEs led to dose interruption in 25 pts (59.5%), dose reduction in 16 pts (38.1%), and treatment discontinuation in 10 pts (23.8%). Conclusions: T-DXd demonstrated promising clinical activity with high ORR and durable responses in pts with HER2-mutated NSCLC. The safety profile was generally consistent with previously reported studies. Clinical trial information: NCT03505710 .

4040 Background: In the phase 2 CheckMate 142 trial, NIVO + low-dose IPI had robust, durable clinical benefit and was well tolerated as 1L therapy for MSI-H/dMMR mCRC (median follow-up 13.8 months [mo; range, 9–19]; Lenz et al. Ann Oncol 2018;29:LBA18). Longer follow-up is presented here. Methods: Patients (pts) with MSI-H/dMMR mCRC and no prior treatment for metastatic disease received NIVO 3 mg/kg Q2W + low-dose IPI 1 mg/kg Q6W until disease progression or discontinuation. The primary endpoint was investigator-assessed (INV) objective response rate (ORR) per RECIST v1.1. Results: In 45 pts with median follow-up of 29.0 mo, ORR (95% CI) increased to 69% (53–82) (Table) from 60% (44.3–74.3); complete response (CR) rate increased to 13% from 7%. The concordance rate of INV and blinded independent central review was 89%. Median duration of response (DOR) was not reached (Table). Median progression-free survival (PFS) and overall survival (OS) were not reached, and 24-mo rates were 74% and 79%, respectively (Table). Nineteen pts discontinued study treatment without subsequent therapy. An analysis of tumor response post discontinuation will be presented. Ten (22%) pts had grade 3–4 treatment-related adverse events (TRAEs); 3 (7%) had grade 3–4 TRAEs leading to discontinuation. Conclusions: NIVO + low-dose IPI continued to show robust, durable clinical benefit with a deepening of response, and was well tolerated with no new safety signals identified with longer follow-up. NIVO + low-dose IPI may represent a new 1L therapy option for pts with MSI-H/dMMR mCRC. Clinical trial information: NTC02060188 . [Table: see text]

1013 Background: C alone has good activity and tolerability in metastatic breast cancer (MBC) and when combined with docetaxel improves response and survival. C combined with B in heavily pretreated MBC improved the response rate but not PFS. In untreated MBC, the addition of B to chemotherapy significantly improves progression-free survival (PFS) which suggests that B, is most effective in early disease. Methods: Primary objective of this single-arm, 2-phase study, is to evaluate PFS in MBC patients receiving first-line treatment with C 1,000 mg/m2 twice daily on days 1–15 (28 doses) and B 15 mg/kg on day 1. Treatment was repeated every 21 days until progression. Eligibility criteria included HER2-negative MBC previously untreated for metastatic disease; ECOG performance status =1; no prior anti-angiogenic or oral fluoropyrimidine therapy. A sample size of 109 patients (including dropouts) was required to give 90% power to test an improvement from 4 months median PFS to 5.6 months with the two-sided test (a 5%) Results: At data cut-off, 103 patients had received study medication. Present results are based on 103 patients (ITT population), except tumor response which is based on 91 patients who had response evaluation. The average # of cycles received in first phase is 6.8. 84 pts.are alive at this time. 38.5% (35/91) pts. have had a response: complete response 5.5%; partial response 33.0%. Stable disease is 42.9% with 81.4% clinical benefit. Planned dose received is 77.7 % for C and 99.0 % for B. The majority of adverse events (AEs) were mild or moderate. The most common grade 3 AEs were hand-foot syndrome (13%) and pain (10%); grade 4 pulmonary embolism occurred in 2% in the first phase of the study. Conclusions: Updated results with longer follow-up including toxicity, TTP and PFS will be presented at the meeting. It appears that in first-line C+B is active for MBC and is well tolerated, with few grade 3/4 toxicities. [Table: see text]

5567 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. Advanced prostate cancer (PC) pts with germline or somatic BRCA1/2 inactivating mutations treated with O are reported. Methods: Eligible pts had advanced PC, no remaining standard treatment (tx) options, measurable disease, ECOG Performance Status (PS) 0-2, and adequate organ function. Tumor genomic testing was performed in CLIA-certified, CAP-accredited site selected labs. Pts received O tablets or capsules dosed at 300 mg (n=24) or 400 mg (n=5), respectively, orally twice daily until disease progression. Simon 2-stage design tested the null disease control (DC) (objective response (OR) or stable disease at 16+ weeks (wks) (SD16+) according to RECIST) 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 tx is worthy of further study. Pts had radiographic evaluations at 8 and 16 wks and then every 12 wks. Secondary endpoints are progression-free survival (PFS), overall survival (OS) and safety. Results: 29 pts with BRCA1/2 inactivating mutations were enrolled from Aug 2016 to Jul 2019; 4 were identified as ineligible after enrollment due to bone only disease and removed from analyses. Demographics and investigator-reported outcomes are summarized in the Table. Nine pts with OR and 8 with SD16+ were observed for DC and OR rates of 68% (90% CI: 53% - 77%) and 36% (95% CI: 18% - 57%), respectively. Six pts had at least one grade 3 AE or SAE at least possibly related to O including anemia, aspiration, dehydration, diabetic ketoacidosis, fatigue, and neutropenia. Conclusions: Monotherapy with O showed anti-tumor activity in heavily pre-treated PC pts with germline (1/2 pts with OR or SD16+) or somatic (16/23 pts with OR or SD16+) BRCA1/2 inactivating mutations. These findings extend results from recent trials of O in advanced prostate cancer pts with germline only BRCA1/2 mutations. Clinical trial information: NCT02693535 . [Table: see text]
