TPS3653 Background: Ataxia telangiectasia and Rad3-related (ATR) is an essential kinase that senses stressed replication forks and orchestrates the multifaceted replication stress response. Cancer cells under replication stress are particularly susceptible to ATR inhibition. Small-cell neuroendocrine cancers (SCNCs) are highly aggressive and arise in multiple tissues, most commonly lung (SCLC). We hypothesized that SCNCs are under replication stress and that exacerbating this stress could selectively kill SCNC by replicative damage. Based on promising data from a single-arm study, this study seeks to evaluate the improvement of progression free survival (PFS) by adding M6620 to topotecan in patients with SCNC. Methods: This study is an investigator-initiated, multicenter, open-label randomized phase 2 clinical trial. Key inclusion criterion are patients at age ≥18 with SCNCs that had relapsed after at least one prior chemotherapy, ECOG PS ≤ 2, and adequate organ function. Patents with asymptomatic brain metastasis, irrespective sensitivity with prior platinum-based chemotherapy, and previously treated with immune checkpoint inhibitors are eligible. The primary cohort consists of 54 patients with SCLC randomized 2:1 to receive either topotecan in combination with M6620 or topotecan alone. Topotecan is administered 1.25 mg/m2 intravenously over 30 minutes every 23 hours on day 1 through 5, pegfilgrastim 6 mg subcutaneously on day 6 and M6620 is administered at 210 mg/m2 intravenously over 60 minutes on day 2 and day 5 if the patient is randomized to the combination arm, in 21-day cycles. Patients randomized to the topotecan alone arm can cross-over to the combination arm at disease progression. An exploratory cohort will enroll 20 patients with SCNC. Primary endpoint is PFS improvement with the combination compared with topotecan alone. Secondary endpoints are ORR and overall survival. To evaluate the genomic features associated with clinical outcomes and to gain insight into the underlying mechanisms of ATR inhibitor response, we require mandatory biopsy before starting treatment.

BackgroundInduction with four cycles of platinum-based chemotherapy was the standard of care for metastatic non-small cell lung cancer (NSCLC) until the approval of immune checkpoint blockade (ICB) in the first-line setting. Switch maintenance therapy has shown promise in improving survival by exposing patients to novel, non-cross–resistant agents earlier in their treatment course.MethodsWe performed this open-label, three-arm, randomized phase II study (NCT02684461) to evaluate three sequences of consolidation with pembrolizumab and nab-paclitaxel in patients without progressive disease post induction chemotherapy. Consolidation was either sequential with pembrolizumab for four cycles followed by nab-paclitaxel for four cycles (P→A), nab-paclitaxel followed by pembrolizumab (A→P), or concurrent nab-paclitaxel and pembrolizumab for four cycles (AP).ResultsTwenty patients were randomized before the study was closed early due to the approval of first-line checkpoint inhibitors. We found that consolidation is feasible and well tolerated, with 30% of patients experiencing grade 3 toxicity. The median progression-free survival and OS in months (95% CI) in P→A were 10.1 (1.5–NR), 27.6 (1.7–NR); 8.4 (1.2–9.0), 12.7 (4.4–NR) in A→P; and 10.2 (5.1–NR), NR. Quality of life as measured by FACT-L improved in the majority of patients during the course of the study.ConclusionSequential and concurrent consolidation regimens are well tolerated and have encouraging overall survival in patients with metastatic NSCLC.

588 Background: Now fluoropyrimidine plus Bmab is considered a recommendable option to the majority of elderly mCRC patients who are deemed inappropriate for the standard doublet chemotherapy with biologics. Our previous phase II study of UFT/ LV in elderly mCRC patients (≥75 years old) had demonstrated acceptable safety and efficacy (overall response rate [ORR] 33%, progression-free survival [PFS] 5.3 months, overall survival [OS] 18 months). The aim of the present study was to investigate the efficacy and safety of Bmab in combination with UFT/LV for elderly mCRC patients. Methods: This study was designed as a single-arm, open-label, multicenter, cooperative group (SGOSG-TCTG) clinical trial (trial registration: UMIN000003515). Key eligibility criteria included age ≥75 years, ECOG performance status (PS) 0 or 1, first-line chemotherapy, measurable lesions, and preserved organ functions. Patients received UFT 300mg/m2/day and LV 75mg/body/day on days 1-21 followed by 7 days rest, and intravenous administration of Bmab 5mg/kg on days 1 and 15. Treatment repeated every 28 days. The primary endpoint was PFS, and secondary endpoints were ORR, OS, and safety. Results: A total of 55 patients were enrolled from 15 institutions between Aug 2008 and Mar 2012. Among them, 52 eligible patients were evaluated. Median age was 80 years (range: 75-87). ECOG PS 0 was 73%. Median PFS was 8.2 months (95% confidence interval [CI], 6.2-10.3, events in 86.5%). Confirmed ORR was 40.4% (95% CI, 27.0-54.9%). Median OS was 18.7 months (95% CI, 10.3-27.0, events in 48%). The most common grade ≥3 treatment-related adverse events were hypertension (11.5%), fatigue (7.7%), nausea (5.8%), and diarrhea (5.8%). The treatment-related death occurred in 2 (3.8%) patients. Main reasons for discontinuation of treatment were disease-progression (62.5%) and toxicity (27.1%). Conclusions: Bmab in combination with UFT/LV is tolerable and effective treatment option for elderly patients (≥75 years old) with mCRC. Further trial with Bmab plus UFT/LV targeting elderly mCRC patients would be warranted. Clinical trial information: 000003515.

8028 Background: SCLC presents as ED-SCLC in 60%-70% of patients (pts). AMR, a synthetic anthracycline, is approved for these pts in Japan. We compare the efficacy and safety of single-agent AMR vs topotecan in non-Japanese pts with 2nd-line ED-SCLC sensitive to 1st-line platinum-based chemotherapy. Methods: This phase II, open-label, multicenter study enrolled pts with ED-SCLC sensitive to 1st-line platinum-based chemotherapy (recurrence or progression ≥90 days from 1st-line treatment). Pts aged ≥18 years with ECOG performance status (PS) ≤2 and only 1 prior therapy were eligible. Pts were randomized (2:1) to receive IV AMR 40 mg/m2/d (d, 1–3) or IV topotecan 1.5 mg/m2/d (d 1–5) and treated every 21 days until progression, unacceptable toxicity, or withdrawal. The primary endpoint, overall response rate (ORR, complete + partial response), used RECIST criteria. Secondary endpoints were progression-free survival (PFS), overall survival (OS), and safety. Results: In all, 76 pts were randomized to AMR (n=50) or topotecan (n=26) with AMR given for a median of 6 cycles (range 1–16) and topotecan 3 cycles (1–16). AMR significantly improved ORR rates vs topotecan (p<0.012; Table ). Median PFS/OS was 4.3 months (95% CI 2.0, 6.1)/9.3 months (95% CI 5.7, 12.0) with AMR vs 3.5 months (95% CI 2.1, 6.3)/8.9 months (95% CI 4.8, 13.8) with topotecan. There was a higher proportion of ECOG PS 2 pts in the AMR group (n=6) vs the topotecan group (n=2). A trend towards improved OS was observed in the ECOG 0–1 subgroup of 68 pts: median OS was 10.5 months with AMR vs 9.7 months with topotecan. The most common grade ≥3 adverse events with AMR vs topotecan were neutropenia (53% vs 74%), thrombocytopenia (31% vs 52%) and leukopenia (27% vs 30%). Three AMR pts (6%) and 1 topotecan pt (4%) died of neutropenic infection. Conclusions: AMR significantly improves ORR and has acceptable tolerability as 2nd-line treatment in pts with sensitive ED-SCLC. [Table: see text] [Table: see text]

9533 Background: Uveal melanoma is the most common primary intraocular malignant tumor in adults. Overall Survival (OS) at 5 years(y) is 62% due high incidence of liver metastasis, fatal within 4-9 months(m) from diagnosis. No standard treatment exists for MUM. NIVO+IPI combination has shown efficacy in metastatic cutaneous melanoma. However, MUM pts were excluded in these trials. Methods: GEM1402 is a phase-2 trial evaluating NIVO+IPI in untreated adult pts with MUM; is being conducted in 10 centers in Spain, leading by the Spanish Melanoma Group. Eligible pts had histologically-confirmed MUM, ECOG-PS 0/1, and no prior systemic treatment for MUM. Treatment consisted in NIVO (1mg/kg, iv, q3 weeks [wk]) and 4 doses of IPI (3mg/kg iv q3wk) followed by NIVO (3mg/kg q2wk) until progressive disease (PD), toxicity or withdrawal. Primary endpoint is OS and secondary progression free survival (PFS), Overall Response Rate (ORR) (per RECIST 1.1) and safety. Radiologic evaluations q6wk. Interim analysis (n = 19) was planned per protocol to assess safety and ORR. Intention to treat analysis includes pts with PD at first radiological evaluation. Safety population includes all pts receiving at least one dose of study treatment. Results:19 pts enrolled from April to July 2016: Median age 62y (43y-82y), 63% male, liver M1 84% pts and extra-liver M1 42% pts, 31% elevated baseline LDH. 11 pts completed cycle 2 and 8 pts stopped after 1 dose (6 PD, 2 toxicity). Treatment-related adverse events were reported in 12 pts and lead to end of treatment in 2 pts. Grade ≥3 toxicities were seen in 7 pts (36.8%): diarrhea, transaminitis, dermatological events, anemia, acute thyroiditis. All G3/4 were resolved following the toxicity guideline. One G5 acute thyroiditis related to NIVO+IPI was reported. ORR was observed in 15.8% and disease stabilization in 47.4%. With a median follow-up of 4.6m, PFS was 4.99m. Median OS was not reached at time of this analysis. Conclusions: Combination of NIVO+IPI is feasible for MUM. In this INTERIM ANALYSIS, ORR did not reach yet 20%, but PFS seems promising. The clinical trial is ongoing. Final results will be updated. Clinical trial information: 2015-004429-15.

440 Background: ATLAS (NCT03397394) evaluated the efficacy/safety of the PARP inhibitor (PARPi) rucaparib in patients (pts) with previously treated locally advanced/unresectable UC or mUC. Methods: Pts with measurable disease who had progressed after 1–2 prior regimens (ie, platinum-based chemotherapy [PBC] and/or immune checkpoint inhibitors [ICI]) were enrolled regardless of tumor homologous recombination deficiency (HRD) status. Prior PARPi was not allowed. Pts received rucaparib 600 mg PO BID. Baseline tumor tissue or archival tissue ≤6 mo without intervening therapy was required; serial circulating tumor DNA samples were collected. Primary endpoint was investigator-assessed objective response rate (RECIST v1.1) in the intent-to-treat and HRD-positive (defined as genomic loss of heterozygosity ≥10%) populations. Key secondary endpoints: progression-free survival (PFS) and safety. Clinical benefit rate (CBR) was defined as complete or partial response or stable disease (SD) lasting ≥16 weeks. Results: As of Oct 7, 2019, 97 pts were enrolled (median age 66 y [range, 39–87]); most were men (n=76, 78.4%) and had ECOG PS 1 (n=65, 67.0%). Sixty-six pts (68.0%) had both prior PBC and ICI. Twenty pts (20.6%) were HRD-positive, 30 (30.9%) were HRD-negative and 47 (48.5%) had unknown HRD status; 4 pts had a deleterious BRCA1/2 alteration. Median time on treatment was 54 d (range, 2–224). There were no confirmed responses. Of 96 evaluable pts, 27 (28.1%) had a best response of SD; CBR was 12.5% and median PFS was 1.8 mo. No relationship was observed between HRD status and clinical activity. Treatment was discontinued by 93 pts (95.9%), mainly due to radiologic or clinical progression (73.1%). Most frequent any grade treatment-emergent (any cause) adverse events were asthenia/fatigue (n=56, 57.7%), nausea (n=40, 41.2%), and anemia (n=34, 35.1%). Conclusions: Single agent rucaparib did not show activity in pts with previously treated advanced UC and enrollment was suspended at the first interim analysis. The safety profile was consistent with that observed in pts with ovarian cancer. Next generation sequencing–based characterization of the genomic landscape of mUC will be presented. Clinical trial information: NCT03397394.

PurposePlatinum-based chemotherapy remains the classic treatment option for patients with advanced non-small-cell lung cancer (NSCLC) who progress while receiving treatment with epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs). In this study, we analyzed real-world outcomes of treatment with immune checkpoint inhibitors (ICIs) combined with platinum-free chemotherapy in patients with NSCLC after developing resistance to EGFR-TKIs.MethodsThis retrospective study included patients with mutation-positive NSCLC after developing resistance to EGFR-TKIs. Patients who received chemotherapy alone plus ICIs with or without anti-angiogenic drugs (cohort A) or platinum-based chemotherapy (cohort B) between February 2019 and August 2020 were enrolled. Clinical characteristics, EGFR mutation status, response to therapy, and adverse events (AEs) were retrospectively analyzed.ResultsSeventeen patients were eligible and included in the analysis, including 8 in cohort A and 9 in cohort B. After a median follow-up of 7.6 months, the median progression-free survival was 6.5 months [95% confidence interval (CI), 6.1 to 7.0] in cohort A and 3.6 months (95% CI, 1.3–5.8) in cohort B (hazard ratios, 0.22; 95% CI, 0.05–0.93; P = 0.039). The overall response and disease control rates were 50% and 100% in cohort A, and 22% and 89% in cohort B, respectively. Adverse events of grade 3 or higher occurred in 25% of the patients in cohort A and in 33.3% of the patients in cohort B.ConclusionICIs plus platinum-free, single-agent chemotherapy provides promising progression-free survival and overall response rate benefit, along with a low rate of severe AEs in patients with EGFR-TKI-resistant advanced NSCLC.

TPS9117 Background: Pembrolizumab-based combination immunotherapy aims to improve clinical outcomes over pembrolizumab monotherapy. A biomarker-based therapeutic approach may be associated with improved response to different combination therapies of immune checkpoint inhibitors and may improve overall outcomes in NSCLC. The randomized, multicenter, open-label, phase 2 KEYNOTE-495 trial ( NCT03516981 ) will evaluate the clinical usefulness of biomarker-informed, pembrolizumab-based combination therapy in patients with treatment-naive, advanced NSCLC. Methods: This is a group-sequential, adaptive randomization trial. Patients will have histologically or cytologically confirmed treatment-naive, advanced NSCLC, documented absence of EGFR and B-Raf mutations and ALK and ROS1 gene rearrangements, measurable disease per RECIST v1.1, and ECOG PS 0-1. Tumor tissue from patients will be initially screened for 2 validated, independent, next-generation biomarkers: T cell–inflamed gene expression profile (GEP) and tumor mutational burden (TMB). Based on results of biomarker screening, patients will be assigned to 1 of 4 groups: TMBlowGEPlow, TMBhighGEPlow, TMBlowGEPhigh, and TMBhighGEPhigh. Within each group, patients will be randomly assigned to receive pembrolizumab 200 mg Q3W intravenously (IV) combined with either MK-4280 200 mg Q3W (anti–LAG-3) IV or lenvatinib 20 mg orally once daily, with the randomization assignment adaptively modified based on interim efficacy analyses. Response will be assessed by imaging every 9 weeks for the first year and every 12 weeks thereafter using RECIST v1.1. Treatment will continue for 35 cycles (~2 years). Patients in the pembrolizumab + lenvatinib arm who complete 35 treatments may continue with lenvatinib monotherapy until disease progression or toxicity. Treatment arms may be terminated during the interim analysis due to safety, prespecified futility criteria, or both. Primary end point is investigator-assessed objective response rate (RECIST v1.1). Secondary end points are progression-free survival, overall survival, and safety. Recruitment and screening are ongoing in more than 8 countries. Clinical trial information: NCT03516981.

6056 Background: A Phase I trial (NCT01116648) of cediranib (cedi) in combination with olaparib (ola) (cedi + ola) demonstrated an overall response rate of 44% in patients (pts) with recurrent ovarian cancer (OC), including pts without a deleterious or suspected deleterious gBRCAm (non-gBRCAm; Liu et al. Eur J Cancer 2013). The subsequent Phase II trial (NCT01116648) showed significant improvement in progression-free survival (PFS) with cedi + ola versus ola monotherapy in recurrent platinum-sensitive OC pts, notably in non-gBRCAm pts (Liu et al. Lancet Oncol 2014). We report data from the Phase IIb, single-arm, open-label CONCERTO study investigating cedi + ola in non-gBRCAm pts with recurrent platinum-resistant OC who had received ≥3 previous lines of therapy for advanced OC (NCT02889900). Methods: Pts with disease progression <6 months from the last receipt of platinum-based chemotherapy received cedi tablets (30 mg once daily) plus ola tablets (200 mg twice daily) until progression or unacceptable toxicity. gBRCAm pts were ineligible. Primary endpoint: objective response rate (ORR) by independent central review (ICR; RECIST 1.1). Key secondary endpoints: PFS and safety. Results: 60 pts from the USA were included (median age: 64.5 years; median number of previous systemic treatment regimens: 4 [range: 2–9]; previous bevacizumab: 53). All pts had high-grade OC (90% serous; 3.3% clear cell; 3.3% endometrioid; 3.3% other). 7% of pts had tumor BRCA2 (confirmed somatic) mutations, 80% of pts had no tumor BRCA mutation (non-tBRCAm) and 13% of pts were not evaluable for tBRCAm. Five (8%) pts who were non-tBRCAm carried somatic homologous recombination repair gene mutations (FoundationOne Clinical Trial Assay, Foundation Medicine, Inc). The Table shows results of key endpoints. Most common grade ≥3 adverse events (AEs) that occurred in pts were hypertension (30%), fatigue (22%) and diarrhea (13%). 37% of pts reported serious AEs, of which nausea (7%) was most common. Dose interruptions, reductions and discontinuations were caused by AEs in 55%, 18% and 18% of pts, respectively, who received cedi + ola. Conclusions: Cedi + ola showed evidence of antitumor activity in heavily pretreated non-gBRCAm pts with recurrent platinum-resistant OC. Toxicity was manageable with dose modifications. Clinical trial information: NCT02889900. [Table: see text]

PURPOSE Patients with metastatic urothelial carcinoma (mUC) who progress on platinum-based combination chemotherapy (PLT) and checkpoint inhibitors (CPIs) have limited options that offer objective response rates (ORRs) of approximately 10% with a median overall survival (OS) of 7-8 months. Sacituzumab govitecan (SG) is a TROP-2–directed antibody-drug conjugate with an SN-38 payload that has shown preliminary activity in mUC. METHODS TROPHY-U-01 (ClinicalTrials.gov identifier: NCT03547973 ) is a multicohort, open-label, phase II, registrational study. Cohort 1 includes patients with locally advanced or unresectable or mUC who had progressed after prior PLT and CPI. Patients received SG 10 mg/kg on days 1 and 8 of 21-day cycles. The primary outcome was centrally reviewed ORR; secondary outcomes were progression-free survival, OS, duration of response, and safety. RESULTS Cohort 1 included 113 patients (78% men; median age, 66 years; 66.4% visceral metastases; median of three [range, 1-8] prior therapies). At a median follow-up of 9.1 months, the ORR was 27% (31 of 113; 95% CI, 19.5 to 36.6); 77% had decrease in measurable disease. Median duration of response was 7.2 months (95% CI, 4.7 to 8.6 months), with median progression-free survival and OS of 5.4 months (95% CI, 3.5 to 7.2 months) and 10.9 months (95% CI, 9.0 to 13.8 months), respectively. Key grade ≥ 3 treatment-related adverse events included neutropenia (35%), leukopenia (18%), anemia (14%), diarrhea (10%), and febrile neutropenia (10%), with 6% discontinuing treatment because of treatment-related adverse events. CONCLUSION SG is an active drug with a manageable safety profile with most common toxicities of neutropenia and diarrhea. SG has notable efficacy compared with historical controls in pretreated mUC that has progressed on both prior PLT regimens and CPI. The results from this study supported accelerated approval of SG in this population.
