Global Leader of Cancer Treatments



Product outline

ATB-301 is a new anti-cancer drug in combination with TGF- β2 Targeting Antisense Oligonucleotide (ASO), which selectively inhibits TGF-β, and IL-2.


- Designed based on the correlation between TGF-β overexpression and tumor progression.

- Inhibits TGF-β2 expression by complementary binding to mRNA.

  • Problem

    - Immuno-oncology drugs are effective, but there is
    a large difference in the response rate by cancer types

    - TGF-β has been found to be the main cause of
    resistance to immuno-oncology drugs.

  • Solution

    - Improving the response rate in various cancer types
    by combination therapy

    - Increasing treatment efficacy by using the substance
    which inhibits TGF-β
