MA26.10 - CNS Activity of Ramucirumab in Combination with Osimertinib in Patients with Advanced T790M-Positive EGFR-Mutant NSCLC (ID 12295)
14:35 - 14:40 | Author(s): James Chih-Hsin Yang
- Abstract
- Presentation
Background
Many patients with NSCLC develop central nervous system (CNS) metastasis. Osimertinib, a novel third-generation EGFR tyrosine kinase inhibitor (TKI), has previously demonstrated CNS and systemic efficacy in patients with EGFR-mutant NSCLC. Combination of an EGFR TKI with a VEGF/VEGFR2-directed monoclonal antibodies (mAb) have shown promising results in EGFR-mutant NSCLC. Ramucirumab, human IgG1 VEGFR2 mAb, was used in combination with osimertinib. Planned exploratory and CNS response analyses aim to examine the safety/efficacy of ramucirumab+osimertinib in patients with CNS metastasis.
a9ded1e5ce5d75814730bb4caaf49419 Method
In this ongoing, open-label, multicenter Phase 1 study (NCT02789345), patients with T790M-positive EGFR-mutant (Ex19del or L858R) NSCLC who had relapsed after first-line EGFR TKI therapy were enrolled. Patients with asymptomatic and stable CNS metastasis (with/without prior radiotherapy) were eligible. Primary objective of the study was to assess safety and tolerability of ramucirumab+osimertinib. Secondary endpoints include objective response rate (ORR) and disease control rate (DCR). Exploratory endpoints relevant to CNS include CNS ORR and CNS DCR.
4c3880bb027f159e801041b1021e88e8 Result
Patients (N=25) were 45-80 years (median 64) with ECOG-PS 0 (n=3) or 1 (n=22) and 10 patients had CNS metastasis at enrollment while 15 never had CNS metastasis. Patients with CNS metastasis could have had prior radiotherapy (n=7) or no radiotherapy (n=3) to the CNS. Median follow-up time was 7.23 months. Fifteen patients remained on study treatment (five with CNS metastasis, ten without). TEAEs of interest (CNS metastasis, no CNS metastasis), such as headache (4/10, 5/15), vomiting (3/10, 4/15), and nausea (2/10, 4/15), were observed with comparable rates in patients with or without CNS metastasis. One patient developed TEAE of cerebral hemorrhage (Grade 1), related to CNS metastasis, but unrelated to study treatment, according to the investigator. Another patient with CNS metastasis developed Grade 5 TRAE of subdural hemorrhage, unrelated to CNS metastasis, ~7 weeks after the last dose of ramucirumab. Only one patient with CNS metastasis had measurable CNS lesions (tumor shrinkage of 24% [SD] as best response). The other nine patients with CNS metastasis had non-measurable CNS lesions, one of whom had a CNS complete response; his systemic best response was SD. The rest of patients had CNS non-CR/non-PD. To date, one patient (1/25) developed CNS progression (due to new CNS lesion); her CNS best response was SD.
8eea62084ca7e541d918e823422bd82e Conclusion
Ramucirumab+osimertinib showed potential antitumor activity in the CNS. Patients with CNS metastasis, with/without prior radiotherapy, appeared to tolerate this combination similarly to patients without CNS metastasis.

P1.01-62 - The Third Generation Irreversible EGFR Inhibitor HS-10296 in Advanced Non-Small Cell Lung Cancer Patients (ID 13138)
16:45 - 18:00 | Author(s): James Chih-Hsin Yang
- Abstract
Background
The epidermal growth factor receptor (EGFR) T790M mutation is the most common mechanism of drug resistance to EGFR tyrosine kinase inhibitors (TKIs) in non-small cell lung cancer (NSCLC) patients with sensitizing EGFR mutations. The third generation irreversible EGFR inhibitor HS-10296 has been shown to be safe and effective against both EGFR TKI-sensitizing and T790M resistance mutations in preclinical studies.
a9ded1e5ce5d75814730bb4caaf49419 Method
A Phase I, open-label, multi-center clinical trial was conducted in patients with locally advanced or distant metastatic NSCLC who have progressed following prior therapy with EGFR TKIs. The study was consisted of dose-escalation cohorts (55, 110, 220 and 260 mg) and dose-expansion cohorts (55, 110 and 220 mg) with once daily oral administration of HS-10296. In each expansion cohort, tumor biopsies were collected for central determination of EGFR T790M status. Patients were assessed for safety, tolerability, pharmacokinetics and efficacy of HS-10296.
4c3880bb027f159e801041b1021e88e8 Result
A total of 117 patients (median age 60) received at least one dose of HS-10296 across multiple sites in China (43 patients), Taiwan (69 patients) and the United States (5 patients). Maximum tolerated dose（MTD）has not been reached in this study. The most common adverse events were grade1/2 rash, pyrexia, upper respiratory tract infection, constipation, diarrhoea and blood creatine phosphokinase elevation. Drug-related serious adverse events were anemia (0.8%), blood creatinine elevation (0.8%), anemiarhabdomyolysis (0.8%) and blood creatine phosphokinase elevation (0.8%) occurred mainly in the cohorts with higher doses at 220 mg or 260 mg, respectively. These data demonstrated favorable tolerability and safety of HS-10296 in patients enrolled. The pharmacokinetics of HS-10296 was dose proportional and the plasma half-life was 30.7~37.5 hours. Among 82 evaluable patients (18 in escalation cohorts and 64 in expansion cohorts) with the EGFR T790M mutation, the overall objective response rate (ORR) was 52.4% (43/82; 95% CI, 41.6 to 63.3), while disease control rate (DCR) was 91.5% (75/82; 95% CI, 85.4 to 97.5). 110mg cohort showed better DCR (97.2% VS. 86.1%) than 55mg cohort. Phase II study is ongoing with the dose at 110 mg.
8eea62084ca7e541d918e823422bd82e Conclusion
HS-10296 has the potential to provide clinical benefit to locally advanced or distant metastatic NSCLC patients with EGFR T790M mutation who had disease progression following prior therapy with EGFR TKIs.

P2.12-04 - Liposomal Irinotecan vs Topotecan in Patients with Small Cell Lung Cancer Who Have Progressed On/After Platinum-Based Therapy (ID 12768)
16:45 - 18:00 | Author(s): James Chih-Hsin Yang
- Abstract
Background
Small Cell Lung Cancer (SCLC) accounts for ~15% of all lung cancers; it is an aggressive disease marked by rapid growth and early metastasis. Patients typically demonstrate initial sensitivity to chemotherapy and radiotherapy, followed by rapid relapse and development of drug resistance. Topotecan, a topoisomerase I (TOP1) inhibitor, is the only agent approved for second-line treatment in the United States and Europe. Liposomal irinotecan (nal-IRI) has demonstrated sustained TOP1 inhibition, with liposomal deposition in tumor tissue through leaky vasculature, followed by irinotecan release and subsequent conversion to the active metabolite SN-38. Pre-clinical data suggests that nal-IRI has improved anti-tumor activity compared to topotecan. The current trial (NCT03088813) is being undertaken to investigate the safety and efficacy of nal-IRI versus intravenous topotecan in patients with SCLC who have progressed on or after platinum-based first-line therapy.
a9ded1e5ce5d75814730bb4caaf49419 Method
There are two parts of this study: Part 1 is an open-label, single-arm, safety run-in phase and Part 2 is a randomized, controlled, efficacy assessment phase. Key inclusion criteria include ECOG performance status of 0–1, adequate organ function, histopathologically/cytologically confirmed SCLC, evaluable disease (RECIST v1.1), and life expectancy ≥12 weeks. Prior exposure of immuno-oncology therapies is allowed. Key exclusion criteria include a diagnosis of large cell neuroendocrine lung carcinoma, prior treatment regimens with TOP1 inhibitors, and retreatment with the same platinum-based regimen after relapse of first-line therapy. In Part 1, patients will be treated with different doses of nal-IRI to identify a tolerable dose level; this dose level will be expanded to include a total of 24 patients. The primary endpoint is safety and tolerability, with secondary endpoints including objective response rate (ORR), progression-free survival (PFS), and overall survival (OS).
In Part 2, ~450 patients will be randomized in a 1:1 ratio between nal-IRI and IV topotecan. The primary endpoint is OS, followed by PFS, ORR, patient-reported outcomes, and exploratory analyses. Patients will be treated for a minimum of 3 cycles (1 cycle = 6 weeks) or until progressive disease or unacceptable toxicity. Safety analyses will be performed using the safety population, defined as all patients receiving any study drug.

P3.16-02 - Phase III Study of Canakinumab (ACZ885) as Adjuvant Therapy in Patients with Surgically Resected NSCLC (ID 12069)
12:00 - 13:30 | Author(s): James Chih-Hsin Yang
- Abstract
Background
Preclinical and clinical data suggest that cytokines such as interleukin (IL)-1β can promote angiogenesis and tumor growth, and are essential to tumor invasiveness. Canakinumab (ACZ885) is a high-affinity human IgGκ anti-IL-1β monoclonal antibody approved for patients with various IL-1–driven auto-inflammatory diseases. In the Phase III Canakinumab Anti-Inflammatory Thrombosis Outcomes Study (CANTOS) in patients with atherosclerosis, canakinumab was associated with a significant reduction in the incidence of fatal and non-fatal lung cancer in patients with increased high-sensitivity C-reactive protein levels. ACZ885T2301 (NCT03447769) is evaluating the efficacy and safety of adjuvant canakinumab versus placebo in patients with surgically resected non-small cell lung cancer (NSCLC).
a9ded1e5ce5d75814730bb4caaf49419 Method
This Phase III, randomized, double-blind, placebo-controlled study is enrolling patients (≥18 years, Eastern Cooperative Oncology Group Performance Status ≤1) with completely resected (R0) American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) v.8 stages II−IIIA and IIIB (T >5 cm and N2) NSCLC, who have completed standard-of-care adjuvant treatments, including cisplatin-based chemotherapy and mediastinal radiation therapy (if applicable). Prior treatment with neoadjuvant chemotherapy or radiotherapy is not permitted. Approximately 1500 patients will be randomized 1:1 to receive canakinumab (200 mg every 3 weeks [Q3W], subcutaneous [s.c.]) or placebo (Q3W, s.c.) on Day 1 of 21-day cycles for 18 cycles or until disease recurrence, unacceptable toxicity, treatment discontinuation at the discretion of the investigator or patient, death, or loss to follow-up. Following baseline screening, imaging assessment will be performed every 12 weeks for the first year (treatment phase) following Cycle 1 Day 1, then every 26 weeks during Years 2 and 3, and annually during Years 4 and 5 (post-treatment surveillance phase). Randomization will be stratified by AJCC/UICC v.8 stage, tumor histology, and region.
The primary objective is to compare disease-free survival (DFS) in the canakinumab versus placebo arms, as determined by local investigator assessment. Secondary objectives include a comparison of the two treatment groups with respect to overall survival (key secondary objective), lung cancer-specific survival, safety, pharmacokinetics and immunogenicity of canakinumab, and patient-reported outcomes. Exploratory objectives include assessment of the relationship between pharmacokinetics, pharmacodynamics, safety, and efficacy, and evaluation of correlation between cytokines/soluble markers and efficacy endpoints. Enrollment is ongoing.

PL02.03 - Brigatinib vs Crizotinib in Patients With ALK Inhibitor-Naive Advanced ALK+ NSCLC: First Report of a Phase 3 Trial (ALTA-1L) (ID 11155)
08:30 - 08:40 | Author(s): James Chih-Hsin Yang
- Abstract
- Presentation
Background
Brigatinib has robust efficacy in crizotinib-resistant ALK+ NSCLC, exhibiting median progression-free survival (mPFS) of 16.7 months. We report results of the first interim analysis from the ALTA-1L study of brigatinib vs crizotinib in ALK TKI-naive, ALK+ NSCLC (NCT02737501).
This open-label, multicenter study enrolled patients with stage IIIB/IV ALK+ NSCLC based on local ALK testing (FDA approved/other). Eligible patients had ECOG PS 0–2, ≤1 prior systemic therapy for locally advanced/metastatic NSCLC, and no prior ALK inhibitor. Asymptomatic CNS metastases were allowed. All patients had systematic CNS imaging. Patients were randomized 1:1 to brigatinib 180 mg QD with 7-day lead-in at 90 mg or crizotinib 250 mg BID. Primary endpoint: blinded independent review committee (BIRC)-assessed PFS (RECIST v1.1). Secondary efficacy endpoints included BIRC-assessed objective response rate (ORR), intracranial ORR (iORR), and intracranial PFS (iPFS). Interim analyses were planned at 50% and 75% of planned PFS events (n=198).
275 patients were randomized (brigatinib/crizotinib, n=137/138); median age (years) 58/60. 26%/27% received prior chemotherapy for advanced disease, and 29%/30% had baseline brain metastases. At data cut-off (19 February 2018), median follow-up brigatinib/crizotinib: 11.0/9.25 months; with 99 PFS events, brigatinib met the prespecified threshold for statistical superiority vs crizotinib in the primary endpoint, BIRC-assessed PFS (HR 0.49, 95% CI 0.33–0.74, log-rank P=0.0007); brigatinib mPFS was not reached (95% CI NR–NR) vs crizotinib 9.8 months (95% CI 9.0–12.9). Investigator-assessed PFS HR 0.45 (95% CI 0.30–0.68), log-rank P=0.0001. Table shows additional efficacy data. Most common treatment-emergent AEs grade ≥3: brigatinib: increased CPK (16.2%), increased lipase (13.2%), hypertension (9.6%); crizotinib: increased ALT (9.5%), AST (5.8%), and lipase (5.1%). Any grade ILD/pneumonitis: brigatinib, 3.7%; crizotinib, 2.2%. Discontinuations due to AE (brigatinib/crizotinib): 11.8%/8.8%.
Brigatinib showed a statistically and clinically significant improvement in PFS compared with crizotinib in ALK inhibitor–naive ALK+ NSCLC.
