By inhibiting active transcription in Tumor

Associated Macrophages (TAMs), lurbinectedin

downregulates IL-6, IL-8, CCL2 and VEGF

Selectively inhibits active transcription of protein-coding genes

through binding to promoters and irreversibly stalling elongating

RNA polymerase II on the DNA template, thereby leading to

double-stranded DNA breaks and apoptosis.

LURBINECTEDIN: SCLC

Market overview: Orphan drug designation granted in the United States and EU

Decision Resources, Inc. expects that in 2018,

there will be approximately 61,300 new cases

of small cell lung cancer in the EU2

The American Cancer Society expects that in 2019

there will be approximately 30,000 new cases of

small cell lung cancer in the United States1

• SCLC represents a significant unmet medical need with limited late stage options.

• The 5-year survival rate is about 5%-10%3

• 2nd line Standard of Care: Topotecan; Median TTP ~3m; OS ~6m4

• Last FDA approved NCE for 2nd line, Topotecan (iv) 1996, (only sensitive patients)

• PHM internal market research estimates ~60% of patients get treated in 2nd line
