Intensity Therapeutics Resumes TNBC Trial with Adjusted Dosing

  • Intensity Therapeutics resumed patient treatment in the INVINCIBLE-4 Phase 2 trial for triple-negative breast cancer (TNBC) on July 15, 2026.
  • The trial evaluates INT230-6 combined with standard-of-care neoadjuvant immuno-chemotherapy versus SOC alone.
  • Protocol amendments include a lower drug-to-tumor volume ratio and single injection of INT230-6 to address skin irritation issues.
  • Prior to the pause, 14 patients were treated, with favorable safety trends observed in the INT230-6 cohort.

Intensity Therapeutics' resumption of the INVINCIBLE-4 trial addresses a critical unmet need in TNBC treatment, where current standard-of-care regimens yield only 63% pCR rates and high toxicity. The company's intratumoral approach with INT230-6 aims to improve outcomes by leveraging localized drug delivery and immune activation. Success in this trial could position Intensity as a key player in the evolving landscape of precision oncology, particularly for aggressive cancer subtypes.
