TUKYSA (tucatinib)
TUKYSA is indicated for the treatment of Breast Cancer; Colorectal Cancer.
How TUKYSA Works
Tucatinib is a tyrosine kinase inhibitor of HER2. In vitro, tucatinib inhibits the phosphorylation of HER2 and HER3, resulting in the inhibition of downstream MAPK and AKT signaling and cell proliferation. It has demonstrated anti-tumor activity in HER2-expressing tumor cells in both in vitro and in vivo settings. The combination of tucatinib and trastuzumab has shown increased anti-tumor activity compared to either drug used alone.

TUKYSA Approval History
What TUKYSA Treats
2 indicationsTUKYSA is approved for 2 conditions since its original approval in 2020. These indications span multiple therapeutic areas including oncology, immunology, and more.
- Breast Cancer
- Colorectal Cancer
TUKYSA Target & Pathway
ProTarget
A receptor tyrosine kinase that promotes cell growth and division. Approximately 20% of breast cancers overexpress HER2, leading to aggressive tumor growth. Targeting HER2 blocks these growth signals and can trigger immune-mediated destruction of cancer cells.
Pathway Context
HER2 forms dimers with other HER family members to activate growth signaling
A receptor that triggers cell growth, proliferation, and survival when activated. Mutations or overexpression of EGFR drive many cancers, particularly lung cancer. Blocking EGFR stops the growth signals that fuel tumor progression.
TUKYSA Competitive Set
ProThree rings of competition based on shared molecular targets and treated indications.
Direct competitors

How We Calculate These Metrics
Trial Activity Stage
Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.
Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.
- Growth: High proportion of early-phase trials (Phase 1/2), active development
- Expansion: Significant Phase 3 activity, approaching or pursuing approvals
- Mature: Substantial Phase 4 post-marketing studies
- Stable: Mixed phase distribution, steady development
- Declining: Low active trial ratio, reduced R&D investment
