IL-1alpha Inhibitors & Biosimilars
2 drugsAbout IL-1alpha
Interleukin-1 alpha (IL-1alpha) is a pro-inflammatory cytokine that mediates the body's immune response. As a signaling protein, it plays a crucial role in inflammation pathways.
IL-1alpha is a valuable drug target in immunology, evidenced by two FDA-approved drugs. However, there is currently no genetic evidence data available linking IL-1alpha to specific diseases.
Two approved drugs, ARCALYST and KINERET, target IL-1alpha, with ARCALYST having 5 indications and KINERET having 4. These drugs are biologics (other) and fusion proteins.

ℹ️ How we calculate- White space opportunity in Recurrent Diffuse Large B-Cell Lymphoma with only 2 trials.
- Emerging modalities (Fusion protein) signal innovation opportunity.
- phase4 represents biological uncertainty with 50% completion.
Top IL-1alpha Drugs
Two companies, BIOVITRUM AB and KINIKSA PHARMACEUTICALS (UK), LTD., have approved drugs targeting IL-1alpha.
The presence of only two players suggests a concentrated market, potentially raising entry barriers.
IL-1alpha Drug Modality Landscape
Modalities
Routes of Administration
IL-1alpha requires biologic approaches (biologic (other)), likely due to its structure or location.
Consider exploring small molecule approaches to differentiate from existing biologics.
📈 Modality Evolution
other biologics pioneered IL-1alpha targeting (2001), with fusion proteins entering more recently (2008).
IL-1alpha Clinical Trials 146 trials
Completion by Phase
| Phase | Total | Completed | Failed | Active | Completion |
|---|---|---|---|---|---|
| Phase 1 | 37 | 22 | 9 | 6 | 71% |
| Phase 2 | 77 | 49 | 13 | 14 | 79% |
| Phase 3 | 25 | 13 | 4 | 8 | 76% |
| Phase 4 | 7 | 2 | 2 | 3 | 50% |

IL-1alpha Drug Approval Timeline (2001 - 2008)
The first drug targeting IL-1alpha was approved in 2001 (KINERET), and the most recent in 2008 (ARCALYST).
The 8-year span between approvals suggests a potentially maturing, but not saturated, market.

How We Calculate These Metrics
Target Attractiveness Score
A 0-100 score based on trial activity, sponsor diversity, and completion rates. Calculated from 107 clinical trials targeting IL-1alpha.
Completion rate: Percentage of trials that reached their planned endpoint. Trials terminated early, withdrawn, or suspended are not counted—these often indicate safety issues, lack of efficacy, or strategic pivots.
- Highly Attractive (80+): High trial activity, many sponsors, strong completion rates
- Attractive (60-79): Good trial activity and validation
- Moderate (40-59): Moderate interest from sponsors
- Low (under 40): Limited trial activity or validation concerns
Strategic Insights
Auto-generated insights based on trial analytics including competition intensity, white space opportunities, modality shifts, and failure patterns. We analyze trial sponsors, phases, indications, and outcomes.
Risk Signals
- High Competition: Many sponsors competing for this target (may reduce market opportunity)
- High Failure Risk: Low trial completion rates suggest development challenges
- Low Validation: Limited trial activity or poor outcomes indicate uncertain viability
- White Space Available: Underexplored indications present opportunities
