    Abstract: 9571 Background: Lazertinib (YH25448) is a highly mutant-selective, irreversible 3 rd -generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that targets the activating EGFR mutations (Del19 and L858R), as well as the T790M mutation, while sparing wild type. Brain metastasis (BM) are common in patients (pts) with advanced NSCLC. Lazertinib showed a high blood-brain barrier penetration profile in preclinical studies. We report intracranial response data in pts with advanced NSCLC from a Phase I/II study of lazertinib (NCT03046992). Methods: Pts with advanced NSCLC, who had progressed after prior EGFR-TKI therapy, were enrolled in an open-label, multicenter, phase I/II study with dose-escalation, dose-expansion and dose-extension phases. Brain MRI was done in all pts at baseline. Pts with asymptomatic BM were eligible for enrollment. Intracranial anti-tumor activity of lazertinib was analysed in pts with BM present on baseline brain scan. Pre-defined intracranial endpoints included objective intracranial response rate (OIRR) and intracranial progression-free survival (IPFS) by independent central review (ICR). The brain metastasis full analysis population included pts with measurable and/or non-measurable BM lesion present on baseline brain scan; the brain metastasis population evaluable for response included only pts with measurable BM lesion. Results: As of 30 Sep 2019, a total of 181 pts received at least one dose of lazertinib 20-320 mg across 7 dose levels. Of those, 64 pts (56% female, median age 63, 86% T790M mutation positive by central testing) were included in the brain metastasis full analysis population; Intracranial disease control rate (IDCR) was 90.6% (58/64; 95% CI 83.5, 97.8) and median IPFS was not reached (95% CI 14.0, NR). In the brain metastasis population evaluable for response, a total of 22 pts were included; OIRR and IDCR were 54.5% (12/22; 95% CI 33.7, 75.4) and 90.9% (20/22; 95% CI 78.9, 100), respectively. In 13 pts (7.2%) out of 181 pts, brain was the first site of disease progression by existing and/or new lesions. Conclusions: Lazertinib demonstrated clinically meaningful activity against BM, aligned with preclinical data. Clinical trial information: NCT03046992 .

    Abstract: 9572 Background: Lazertinib (YH25448) is a highly mutant-selective, irreversible 3 rd -generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that targets the activating EGFR mutations (Del19 and L858R), as well as the T790M mutation, while sparing wild type. We report the efficacy and safety results of lazertinib 240 mg as recommended phase 2 dose (RP2D) from a phase I/II study of lazertinib (NCT03046992). Methods: Patients (pts) with advanced NSCLC, who had progressed after prior EGFR-TKI therapy were enrolled in an open-label, multicenter, phase I/II study with dose-escalation (20-320 mg), dose-expansion (40-240 mg) and dose-extension phases. Pts were assessed for safety, tolerability, pharmacokinetics and efficacy. For dose-expansion and extension phases, tumors had to be T790M mutation-positive (T790M+). Of all 78 pts assigned to lazertinib 240 mg dose level across all phases, 76 pts with centrally confirmed T790M+ were included for efficacy analysis. Results: As of 30 Sep 2019, a total of 78 pts (49% female, median age 62) received at least one dose of lazertinib 240 mg. The median duration of follow-up was 9.6 months and 44 pts were ongoing at data cut-off. Of 78 pts, 76 pts with centrally confirmed T790M+ showed the objective response rate (ORR) 57.9% (95% CI 46.8, 69.0), the disease control rate (DCR) 89.5% (95% CI 82.6, 96.4), the median progression-free survival (PFS) 11.0 months (95% CI 5.6, 16.4) and the median duration of response (DoR) 13.8 months (95% CI 9.6, NR) by independent central review (ICR), respectively. Two pts (3%) experienced a confirmed complete response. The investigator-assessed ORR, DCR, median PFS and median DoR were 72.4% (95% CI 62.3, 82.4), 94.7% (95% CI 89.7, 99.8), 13.2 months (95% CI 9.6, not reached) and 11.8 months (95% CI 8.4, not reached), respectively. The most common treatment-emergent adverse events (TEAEs) at the 240 mg dose regardless of its causality were rash (35%), pruritus (33%) and paraesthesia (32%), which were mostly mild (Grade ≥3 rash: 1%; no Grade ≥3 pruritus or paraesthesia). TEAEs leading to dose reduction and dose discontinuation were observed in 13% (10/78) and 8% (4/78), respectively. Drug related TEAEs of grade ≥3 were observed in 6% (5/78). Conclusions: Lazertinib 240 mg has a favorable safety profile, and exhibits promising anti-tumor activity in pts with EGFR T790M+ NSCLC. Clinical trial information: NCT03046992 .

    American Society of Clinical Oncology (ASCO) ; 2020

    Abstract: 9601 Background: While EGFR mutant ( EGFRm) non-small cell lung cancer (NSCLC) patients usually experience improved clinical benefit with EGFR TKIs, most eventually progress. Understanding mechanisms of resistance (MoR) may allow for more personalized treatment. Lazertinib is an irreversible third generation EGFR TKI for which MoR are unknown. Obtaining sufficient tumor tissue for genotyping at progression is often difficult. Therefore, we utilized plasma ctDNA from patients treated with lazertinib to explore MoR. Methods: Plasma samples from 47 NSCLC patients in the phase 2 trial of lazertinib (NCT03046992) were collected at screening and progressive disease (PD) and underwent ctDNA NGS of 74 genes using Guarant360. All patients were positive for an EGFR Ex19del or L858R ( EGFRm) and T790M by tissue testing at screening. Acquired, nonsynonymous, characterized mutations detected in a PD sample but not in the screening sample from the respective patient were considered putative MoR, excluding aneuploidy. Patients with detectable plasma EGFRm and/or T790M at screening were evaluable. Results: ctDNA was detected in 47 (100%) screening samples and 43/45 (96%) PD samples (two failed sequencing). An EGFRm was detected in 85% of patients at screening (n = 40), 38 of which had PD ctDNA results and were included in analysis. T790M was detected in 30 patients at screening and subsequently not detected at PD in 21 of these patients, 55% of all 38 included patients. Among the ten patients with T790M detected at PD, on-target MoR were detected in 7 (18% of all included patients) including EGFR C797S (n = 3, 8%), EGFR amplification (n = 3, 8%), and EGFR T854A (n = 1, 3%). All C797S were in cis with T790M. No on-target MoR were detected in patients without T790M detected at PD. Off-target MoR were seen in 34% of patients (13/38) including mutations in PIK3CA (13%; 2 E545K, 2 E542K, 1 E81K), ERBB2 (5%; 1 D769H, 1 V777L), KRAS (3%; 1 G12C), and BRAF (3%; 1 G469A). Gene amplifications were detected in CCND1 (n = 1, 3%) , CCNE1 (n = 2, 5%) , ERBB2 (n = 1, 3%) , FGFR1 (n = 1, 3%) , MET (n = 4, 11%) , and PIK3CA (n = 1, 3%), with some patients having multiple MoR. Conclusions: The spectrum of MoR identified in this cohort of patients treated with lazertinib is similar to that reported in other third generation EGFR TKIs, but with some differences in frequencies. The most common resistance mechanisms are T790M loss and PIK3CA alterations which may address the mechanism of action. Our findings suggest putative MoR of lazertinib and show that ctDNA NGS is an effective way to identify MoR in patients progressing on targeted therapy. Clinical trial information: NCT03046992 .

    Abstract: 9037 Background: Lazertinib (YH25448) is a highly mutant-selective, irreversible 3 rd -generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that targets the activating EGFR mutations (Del19 and L858R), as well as the T790M mutation, while sparing wild type. We report the updated results from a Phase I/II study of lazertinib (NCT03046992). Methods: Patients with advanced and metastatic NSCLC who had progressed after treatment with standard EGFR-TKIs with/without asymptomatic brain metastases (BM) were enrolled in an open-label, multicenter, phase I/II study with dose-escalation and expansion cohorts. Lazertinib was administered once daily at doses between 20 to 320 mg in a 21-day cycle. Patients were assessed for safety, tolerability and efficacy. T790M mutation was required in the dose-expansion cohorts. Results: As of 26 Nov 2018, a total of 127 patients were enrolled. The dose-escalation cohort included 38 patients administered with 20 to 320 mg across 7 dose levels, and 89 patients in the dose-expansion cohort were administered with 40 to 240 mg across 5 dose levels. No dose-limiting toxicities were observed. The median duration of treatment was 9.7 months and 58 patients are still ongoing. The objective response rate (ORR) was 60% in all patients, 64% in T790M+ patients, and 37% in T790M- patients by investigators assessment. In BM patients with measurable lesion (n = 14), the intracranial ORR was 50%. The median progression-free survival (PFS) was 8.1 months in all patients, 9.5 months in T790M+ patients, and 5.4 months in T790M- patients. Subgroup analysis showed that ORR was 65% and PFS was 12.2 months in T790M+ patients with ≥ 120 mg (n = 62). The most common treatment-emergent adverse events (TEAEs) were pruritus (27%), rash (24%), constipation (20%), decreased appetite (19%) and diarrhea (14%). TEAEs leading to dose discontinuation were observed in 3% of patients. Drug related TEAEs of grade ≥ 3 was observed in 3% of the patients. Conclusions: Lazertinib was safe, well-tolerated and exhibits promising systemic and intracranial antitumor activity in EGFR T790M+ NSCLC patients. Dose extension cohorts in the 1st and 2nd line settings are underway at 240 mg dose. Clinical trial information: NCT03046992.

    Abstract: 9633 Background: Combination of aprepitant, 5-HT 3 receptor antagonist and steroid improve complete response (CR) of chemotherapy induced nausea and vomiting (CINV). But until now, there was no information whether ramosetron is as effective as other 5-HT 3 receptor antagonists for the combination regimen. Therefore, we compared a ramosetron, aprepitant and dexamethasone (RAD) with ondansetron, aprepitant and dexamethasone (OAD) to establish the non-inferiority of RAD in controlling highly emetogenic chemotherapy induced nausea and vomiting. Methods: A total of 334 patients with malignant disease who were scheduled to receive highly emetogenic chemotherapy were randomized to RAD or OAD. Aprepitant (125 mg day 1; 80 mg day 2, 3) and dexamethasone (12 mg day 1; 8 mg day 2-4) were administered to both group. Intravenous ramosetron (0.3mg day 1) or ondansetron (16mg day1) was given to RAD or OAD, respectively. Patients recorded vomiting and nausea (VAS score) on the diary. The primary end point was CR (no vomiting or retching and no rescue medication) rate in the acute period (chemotherapy day 1). The non-inferiority margin was defined as -15% differences. Results: 299 patients (RAD 143, OAD 156) were eligible for the efficacy analyses of modified intention-to-treat. Median age and sex were 60 (IQR 52 – 66) and 61 (51.5 – 68, p=0.54), 90 Male/66 Female and 114 Male/29 Female (p 〈 0.0001) in RAD and OAD, respectively. There were no significant differences between two groups on the other baseline characteristics. The CR rates of RAD vs OAD were 84.6% vs 77.6% (95% C.I. -0.4 – 14.5%) at acute period, 69.5% vs 62.6% (-2.1 – 16.0%) at delayed period (days 2-5), and 66.7% vs 58.1% (-0.6 – 17.8%) at overall period. Median nausea score at acute period were 4 (IQR 2 – 5) and 3 (2-5, p=0.14) in RAD and OAD, respectively. There were no grade 3 or 4 toxicities. Conclusions: RAD regimen is as effective and tolerable as OAD antiemetic combination for the prevention of CINV in patients receiving highly emetogenic chemotherapy. Ramosetron could be considered as one of the best partners for aprepitant. Clinical trial information: NCT01536691.

    Abstract: TPS9636 Background: In patients with activating EGFR mutations and ALK fusion, target specific tyrosine kinase inhibitor (TKI) showed significant survival improvement compared to the cytotoxic chemotherapy. However, the questions remain which combination strategy will be the best option for the patients who have failed from TKI. Especially, the role of an immune checkpoint inhibitor (ICI) in this population is still unclear. This study is designed and conducted based on the recent subgroup analyses from the IMpower 150 study which showed the positive clinical outcomes of atezolizumab combined with VEGF inhibitor and conventional cytotoxic chemotherapy in EGFR mutation and ALK translocation. Methods: This study is the phase III, open-label, multicenter study of atezolizumab in combination with bevacizumab + carboplatin + paclitaxel (ABCP, Arm A) compared with pemetrexed + cisplatin or carboplatin (Arm B). The study population will be randomized to either Arm A (n = 152) or Arm B (n = 72) based on two stratification factors, EGFR vs. ALK and presence of brain metastases. In Arm A, patients will be treated with 4 or 6 cycles of ABCP followed by maintenance atezolizumab and bevacizumab every three weeks. In Arm B, pemetrexed maintenance therapy will be applied every three weeks after 4 or 6 cycles of pemetrexed + cisplatin or carboplatin. As key inclusion criteria, the patients must be diagnosed with stage IV non-squamous non-small cell lung cancer with either activating EGFR mutation or ALK translocation. All the patients need to be cytotoxic chemotherapy naïve and must have experienced disease progression to treatment with at least one EGFR or ALK TKI. If the patients have T790M mutation after 1 st or 2 nd generation EGFR TKI, second line 3 rd generation EGFR TKI treatment is mandatory. The number of T790M positive patients is restricted to under 30% of the entire study population. The primary endpoint is progression-free survival and the major secondary endpoints are overall survival, objective response rate and duration of response. A total of 228 subjects will be enrolled to detect a hazard ratio of 0.67. The first subject received treatment in Aug. 2019 and 19 patients receive the treatment. This study is opened in 3 sites and expected to be opened at 18 sites in South Korea. The time point for the primary analyses is Q3. 2022. Clinical trial information: NCT03991403 .

    Abstract: e13104 Background: The aim of this study was to determine the maximum tolerated dose (MTD) and recommended dose of docetaxel-PNP when administered every 3 weeks in patients with advanced solid malignancies. Methods: Three to six patients received docetaxel at dose levels of 20-75 mg/m 2 as 60-min infusions every 3 weeks according to the single dose-escalating 3+3 method. Blood samples at the first dose of docetaxel-PNP were collected for PK analysis. Results: Nineteen pts were treated for a median of two cycles (1-14) in the phase I study. Dose escalation was performed up to 75 mg/m 2 . The most frequently reported adverse events were grade 4 neutropenia (52.6%, 10/19), grade 1 myalgia (42.1%, 8/19) and grade 1 alopecia (42.1%, 8/19). No acute infusion reactions were noted. Two dose-limiting toxicity was observed at 20 and 60 mg/m 2 , which were grade 3 hypophosphatemia and death of unknown cause, respectively. Although the MTD was not determined, the recommended dose was determined as 60 mg/m 2 . This was based on neutropenia and PK parameters which are summarized in the table. PK parameters revealed dose linearity. Partial response was seen in one patient and stable disease in seven patients. Conclusions: Administration of docetaxel-PNP was well tolerated up to 60 mg/m 2 every 3 weeks by heavily pretreated patients. Further phase II trials are recommended at this dose level.

    Abstract: To determine the efficacy of consolidation chemotherapy (CC) with docetaxel and cisplatin (DP) after concurrent chemoradiotherapy (CCRT) with the same agents in locally advanced non–small-cell lung cancer (LA-NSCLC). Patient and Methods Patients were randomly assigned to either CCRT alone (observation arm) or CCRT followed by CC (consolidation arm). CCRT with docetaxel (20 mg/m 2 ) and cisplatin (20 mg/m 2 ) was administered every week for 6 weeks with a total dose of 66 Gy of thoracic radiotherapy in 33 fractions. In the consolidation arm, patients were further treated with three cycles of DP (35 mg/m 2 each on days 1 and 8, every 3 weeks). The primary end point was 40% improvement in progression-free survival (PFS) compared with observation. Results From October 2005 to April 2011, 437 patients were randomly assigned. Seventeen patients did not start CCRT as a result of consent withdrawal or ineligibility reasons after random assignment, leaving 420 patients for this analysis (n = 211 for observation; n = 209 for consolidation). Patient characteristics were similar in both arms. In the consolidation arm, 143 patients (68%) received CC, of whom 88 (62%) completed three planned cycles. The median PFS was 8.1 months in the observation arm and 9.1 months in the consolidation arm (hazard ratio, 0.91; 95% CI, 0.73 to 1.12; P = .36). Median overall survival times were 20.6 and 21.8 months in the observation and consolidation arms, respectively (HR, 0.91; 95% CI, 0.72 to 1.25; P = .44). Conclusion CC with DP after CCRT with weekly DP in LA-NSCLC failed to further prolong PFS. CCRT alone should remain the standard of care.

    Abstract: 2069 Background: AZD3759 is the first EGFR inhibitor primarily designed to effectively cross the blood brain barrier (BBB) to treat central nervous system (CNS) metastases. A phase I study is ongoing to assess AZD3759 in EGFRm NSCLC patients with leptomeningeal metastasis (LM) who progressed after other treatment (NCT02228369). Methods: The primary objective is safety and tolerability, and secondary objectives include anti-tumor efficacy. Two dose levels of AZD3759, 200 mg and 300 mg BID, were assessed. Results: As of24 September, 2016,38 patients were recruited into the expansion cohorts of this phase I study. Of those, 18 were TKI pre-treated EGFRm NSCLC patients with LM. 10 and 8 patients were in the 300 and 200 mg BID cohorts, respectively. No DLTs were observed at either dose, while AZD3759 was better-tolerated at 200 than 300 mg BID during 〉 2 month treatment. The longest duration on treatment was 〉 9 months. Most common AEs included skin rash and diarrhea. 67% (12 out of 18) patients had drug-related dose interruption and/or reduction, however, there were no drug-related discontinuations.The C trough free plasma and CSF exposure were above pEGFR IC 90 at the two doses. 40% of patients (4 out of 10) had 〉 50% inhibition of pEGFR in CSF tumor cells at C1D8, and 70% of patients (7 out of 10) had reduced EGFR copy numbers in CSF at C3D1. 53% of evaluable patients (9 out of 17) had confirmed improved/stable LM MRI imaging. 2 out of 3 patients with concomitant measurable BM lesions achieved confirmed/unconfirmed partial CNS response. Among 18 patients with measurable extracranial lesions, 6 (33%) had confirmed stable extracranial disease as best response. 3 patients achieved clearance of tumor cells in CSF by two consecutive assessments. After 6 months follow-up, 29% patients (5 out of 17 evaluable) were still surviving, plus 5 surviving patients with less than 6 months follow-up. Conclusions: AZD3759 was well-tolerated, achieved sufficient CNS exposure for target inhibition and demonstrated promising anti-tumor activity in patients with LM who progressed after multiple lines of treatment. Updated clinical data will be shared at the meeting. Clinical trial information: NCT02228369.
