      OA13.02 - Two Novel Immunotherapy Agents Targeting DLL3 in SCLC: Trials in Progress of AMG 757 and AMG 119 (ID 14538)

      Background
      Small cell lung cancer (SCLC) is an aggressive neuroendocrine tumor characterized by initial response to chemotherapy and radiotherapy followed by relapse or progression with chemoresistant disease. Delta-like ligand 3 (DLL3) is an inhibitory Notch ligand that is specifically upregulated in SCLC. IHC profiling of tumor samples showed DLL3 expression in 86% of SCLC tumors and minimal expression in normal tissue.
      We are conducting clinical trials of two novel immunotherapy agents that target DLL3. AMG 757 is a half-life extended bispecific T cell engager (BiTE®) antibody construct that is designed to transiently crosslink DLL3-positive SCLC cells to CD3-positive T cells and induce T cell–mediated tumor cell lysis and concomitant T cell proliferation. AMG 119 is an adoptive cellular therapy that consists of a patient’s autologous T cells that have been genetically modified ex vivo to express a transmembrane chimeric antigen receptor that targets DLL3 on the surface of SCLC cells. Both AMG 119 and AMG 757 showed potent killing of SCLC cell lines with a broad range of DLL3 expression in vitro and inhibition of tumor growth in the SHP-77 human SCLC xenograft model in vivo. AMG 757 was well tolerated in a preclinical multi-dose GLP toxicology study, with no evidence of tissue damage at weekly doses as high as 4.5 mg/kg.
      a9ded1e5ce5d75814730bb4caaf49419 Method
      NCT03319940 is an open label, phase 1 study evaluating the safety, tolerability and pharmacokinetics of AMG 757 that will initially enroll adult patients with SCLC who have progressed or recurred following platinum-based chemotherapy. Key inclusion criteria: ECOG PS 0–2, life expectancy ≥12 weeks, at least 2 measurable lesions per modified RECIST 1.1 criteria, and adequate organ function. The study will later enroll patients with extended disease SCLC with ongoing clinical benefit following no more than 6 cycles of first-line platinum-based chemotherapy. AMG 757 will be administered as an intravenous infusion once every 2 weeks.
      NCT03392064 is an open-label, phase 1 study evaluating the safety, tolerability and efficacy of AMG 119 in adult patients with SCLC whose disease has progressed or recurred after at least one platinum-based regimen. Key inclusion criteria: ECOG PS 0–1, at least 2 measurable lesions per modified RECIST 1.1 criteria, no evidence of CNS metastasis, and adequate organ function. AMG 119 will be administered as a one-time intravenous infusion.
      Both of these studies are currently enrolling patients. For more information, please contact Amgen Medical Information: medinfo@amgen.com.

      P1.01-02 - Long-Term Outcomes with First-Line Nivolumab Plus Ipilimumab in Advanced NSCLC: 3-Year Follow-Up from CheckMate 012 (ID 12380)

      16:45 - 18:00  |  Author(s): Hossein Borghaei

      • Abstract

      Background

      CheckMate 012 (NCT01454102) is a phase 1 study evaluating several nivolumab monotherapy/combination regimens as first-line treatment for advanced non-small cell lung cancer (NSCLC). CheckMate 012 was the first study to suggest the benefit of nivolumab plus ipilimumab in NSCLC. In the phase 3 study CheckMate 227, nivolumab plus ipilimumab recently demonstrated significantly improved progression-free survival (PFS) as well as more frequent, deeper, and more durable responses versus chemotherapy in patients with chemotherapy-naive advanced NSCLC and high tumor mutational burden (TMB). Here, we provide 2-year follow-up results for nivolumab plus ipilimumab from CheckMate 012. Three-year results, the longest follow-up to date for an immuno-oncology combination in NSCLC, will be presented.

      a9ded1e5ce5d75814730bb4caaf49419 Method

      Eligible patients had recurrent stage IIIb or stage IV chemotherapy-naive NSCLC and Eastern Cooperative Oncology Group performance status 0–1. Patients received nivolumab 3 mg/kg every 2 weeks plus ipilimumab 1 mg/kg every 12 weeks (n=38) or every 6 weeks (n=39) until disease progression, unacceptable toxicity, or consent withdrawal; pooled results of these two cohorts are presented. Endpoints included safety/tolerability (primary); objective response rate and PFS (secondary); and overall survival (OS), chemotherapy-free survival (CFS), and efficacy by TMB status (exploratory).

      4c3880bb027f159e801041b1021e88e8 Result

      With 2 years of follow-up, no new safety signals were observed. Thirty-three of 77 patients (43%) achieved objective responses, including six investigator-assessed complete responses (8%), three of which were complete pathological responses. Responses were durable (median duration of response, not reached; range, 1.4+ to 27.9+ months). The 2-year PFS rate was 29%. At the time of database lock, 32 of 34 patients (94%) with OS ≥2 years were alive, with four (12%) remaining on treatment and progression-free; 14 (41%) were off treatment and progression-free without subsequent therapy. Three-year follow-up results to be presented include OS, PFS, and select data on CFS, efficacy by TMB status, and characteristics of long-term survivors.

      8eea62084ca7e541d918e823422bd82e Conclusion

      With long-term follow-up, nivolumab plus ipilimumab continued to demonstrate durable clinical benefit and a consistent safety profile as first-line treatment for patients with advanced NSCLC.
