Amgen Presents First Clinical Data for AMG 757 at SITC 2020

Data Marks the First Proof of Concept for a BiTE® Molecule in Thoracic Malignancy and Further Demonstrates Potential of BiTE® Immuno-Oncology Platform in Solid Tumors

Data From Four Additional Immuno-Oncology Molecules Will Also be Featured

THOUSAND OAKS, CA, USA I November 9, 2020 I Amgen (NASDAQ: AMGN) today announced the first presentation of AMG 757 Phase 1 clinical safety and efficacy data in relapsed or refractory small cell lung cancer (SCLC). AMG 757 is an investigational half-life extended (HLE) bispecific T cell engager (BiTE®) molecule targeting delta-like ligand 3 (DLL3). The DLL3 protein is overexpressed on the cell surface of SCLC tumors and minimally expressed in normal tissues.Data will be featured during a live oral presentation on Nov. 12 at the Society for Immunotherapy of Cancer's (SITC) 35th Annual Meeting being held virtually.

"These AMG 757 proof of concept data in small cell lung cancer and the recently presented AMG 160 data in prostate cancer provide encouraging evidence of the BiTE platform's clinical activity in solid tumors," said David M. Reese, M.D., executive vice president of Research and Development at Amgen. "AMG 757 is a half-life extended BiTE immuno-oncology molecule targeting DLL3, which is an attractive target due to its differential expression in small cell lung cancer. Small cell lung cancer is a large unmet medical need globally, and yet treatment options have not advanced significantly in decades."

This interim analysis of the Phase 1 dose escalation study evaluated 40 patients with relapsed/refractory SCLC at a dose of up to 10 mg every two weeks. In this study, AMG 757 demonstrated an acceptable safety profile and showed preliminary evidence of anti-tumor activity. Among 38 patients with evaluable disease, 16% (6) had confirmed partial response, 29% (11) had stable disease, and 3% (1) had unconfirmed partial response. Five of the six responses are on-going with a median follow-up of 8.8 months. The maximum tolerated dose for AMG 757 has not been reached and dosing optimization is ongoing.

Cytokine release syndrome (CRS) was the most common treatment-related adverse event (AE) reported in 43% (17) of patients. All CRS events were grade 1 (30%) or 2 (13%), typically occurred in cycle 1, and did not recur in subsequent cycles. All CRS events were reversible, manageable, and did not lead to treatment interuptions or discontinations.

"Small cell lung cancer is an aggressive cancer resulting in poor prognosis for patients. Current platinum-based chemotherapy and immunotherapy options have limited benefit in patients with small cell lung cancer, leaving patients in need of novel therapeutic options," said Hossein Borghaei, DO, MS, chief of thoracic medical oncology at Fox Chase Cancer Center. "These early data of AMG 757 are encouraging for a BiTE immuno-oncology molecule that targets DLL3 in small cell lung cancer."

Additional Data Presentations
Data on IMLYGIC® (talimogene laherparepvec) will be featured during an oral presentation.  Data on AMG 404, AMG 160, and AMG 509 will be presented as poster presentations. More information can be found on the SITC website here.

About BiTE® Technology 
BiTE® (bispecific T cell engager) technology is a targeted immuno-oncology platform that is designed to engage patient's own T cells to any tumor-associated antigen, activating the cytotoxic potential of T cells to eliminate detectable cancer. The BiTE immuno-oncology platform has the potential to treat different tumor types through tumor-associated antigens. The BiTE platform has a goal of leading to off-the-shelf solutions, which have the potential to make innovative T cell treatment available to all providers when their patients need it. Amgen is advancing more than a dozen BiTE molecules across a broad range of hematologic malignancies and solid tumors, further investigating BiTE technology with the goal of enhancing patient experience and therapeutic potential.

About IMLYGIC® (talimogene laherparepvec)
IMLYGIC is a genetically modified herpes simplex type 1 virus that is injected directly into tumors. IMLYGIC replicates inside tumor cells and produces GM-CSF, an immunostimulatory protein. IMLYGIC then causes the cell to rupture and die in a process called lysis. The rupture of the cancer cells causes the release of tumor-derived antigens, which together with virally derived GM-CSF may help to promote an anti-tumor immune response. The exact mechanism of action continues to be investigated.

IMLYGIC is the first and only oncolytic viral therapy approved by the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), and other regulatory authorities, based on therapeutic benefit demonstrated in a pivotal Phase 3 study. IMLYGIC is indicated for the local treatment of melanoma in patients with unresectable cutaneous, subcutaneous, or nodal lesions after initial surgery.

The IMLYGIC clinical program continues to investigate the role of IMLYGIC both as monotherapy and in combination with other therapies across a variety of cancers and treatment settings.

IMLYGIC® (talimogene laherparepvec) is a genetically modified oncolytic viral therapy indicated for the local treatment of unresectable cutaneous, subcutaneous, and nodal lesions in patients with melanoma recurrent after initial surgery.

Limitations of use: IMLYGIC® has not been shown to improve overall survival or have an effect on visceral metastases.
