AMGEN PRESENTS NEW TARLATAMAB CLINICAL DATA AT WCLC 2022

Phase 1 Tarlatamab Study Showed Encouraging Antitumor exertion With Median Duration of Response of 13 Months in Small Cell Lung Cancer

No Approved Treatment Options Available to Cases in Third- line Setting
THOUSAND OAKS,Calif.,Aug. 8, 2022/ PRNewswire/– Amgen( NASDAQ AMGN) moment blazoned new data from the DeLLphi300 clinical trial, a Phase 1 cure disquisition and expansion study assessing the safety and efficacity of investigational tarlatamab, a implicit first- in- class half- life extended bispecific T- cell engager( HLE BiTE ®) patch targeting delta- suchlike ligand 3( DLL3), in small cell lung cancer( SCLC). streamlined data from the ongoing Phase 1 study were presented at the International Association for the Study of Lung Cancer( IASLC) 2022 World Conference on Lung Cancer( WCLC) in Vienna, Austria.

” Small cell lung cancer is one of the most ruinous and aggressive solid excrescence cancers. The complaint has demanded effective treatments with no curatives specifically approved to treat cases in the third- line setting,” said DavidM. Reese,M.D., administrative vice chairman of Research and Development at Amgen.” Our Phase 1 data for tarlatamab presented before moment at WCLC continues to demonstrate instigative antitumor exertion with remarkable response continuity in heavilypre-treated cases. We’re encouraged by the overall survival of13.2 months.”
In heavily pretreated cases with SCLC( n = 106), a population with many treatment options beyond first- line, investigational tarlatamab demonstrated encouraging antitumor exertion with notable response continuity. Tarlatamab delivered a verified ORR of 23( verified and unconfirmed responses), a median duration of response of13.0 months and a median overall survival( zilches) of13.2 months. Treatment- related adverse events( TRAEs) of any grade passed in 97 cases( 92), and TRAEs grade ≥ 3 passed in 33 cases( 31). Cytokine release pattern( CRS) was primarily grade1/2, substantially passed in Cycle 1, infrequently passed in posterior cycles and was generally manageable. Overall, treatment termination due to treatment- related AEs was low( 4).

Grounded on these data, a potentially registrational Phase 2 study of tarlatamab in the third- line treatment of SCLC is presently enrolling cases. fresh studies probing tarlatamab are underway, including DeLLphi- 303, a Phase 1b study testing tarlatamab in combination with standard of care in first- line SCLC and a Phase 1b study in de novo or treatment- imperative neuroendocrine prostate cancer.
About Tarlatamab
Tarlatamab is an investigational implicit first- in- class half- life extended bispecific T- cell engager( BiTE) patch that’s uniquely designed to target delta- suchlike ligand 3( DLL3) in neuroendocrine cancers, similar as small cell lung cancer( SCLC) and neuroendocrine prostate cancer – both of which have high unmet medical requirements,2 DLL3 is largely upregulated on the cell face of neuroendocrine excrescences and infrequently expressed on nonmalignant cells, making it a new target for probing a BiTE immuno- oncology patch

Tarlatamab is being delved in multiple studies, including DeLLphi- 301, a potentially registrational Phase 2 study in regressed/ refractory SCLC; DeLLphi- 303, a Phase 1b study testing tarlatamab in combination with standard of care curatives in first- line SCLC; DeLLphi- 302, a Phase 1b combination study with AMG 404 in alternate- line or latterly SCLC; and DeLLpro- 300, a Phase 1b study in de novo or treatment- imperative neuroendocrine prostate cancer.

About Small Cell Lung Cancer
Small cell lung cancer( SCLC) is a particularly aggressive form of the complaint that accounts for about 10 to 15 of all lung cancers.5 SCLC tends to spread briskly than NSCLC, with nearly 70 of people with SCLC having metastatic complaint at the time of opinion.5
The five- time survival rate for advanced SCLC remains low at 3 and unfortunately treatment options haven’t changed much in several decades,7 Delta- suchlike ligand 3( DLL3) is an arising treatment target that’s expressed in lesser than 80 of SCLC excrescences with minimum expression in normal cells.8

About BiTE ® Technology
BiTE ®( bispecific T- cell engager) technology is a targeted immuno- oncology platform that’s designed to engage case’s own T cells to any excrescence-specific antigen, cranking the cytotoxic eventuality of T cells to exclude sensible cancer. The BiTE immuno- oncology platform has the implicit to treat different excrescence types through excrescence-specific antigens.

The BiTE platform has a thing of leading to out- the- shelf results, which have the eventuality to make innovative T- cell treatment available to all providers when their cases need it. Amgen is advancing a number of BiTE motes across a broad range of hematologic malice and solid excrescences, further probing BiTE technology with the thing of enhancing patient experience and remedial eventuality.
