HERTHENA-PanTumor01 (U31402-277): A Phase 2, Multicenter, Multicohort, Open-Label, Proof of Concept Study of Patritumab Deruxtecan (HER3-DXd; U3-1402) in Subjects With Locally Advanced or Metastatic Solid Tumors

Investigational drug late phase

The trial is testing an investigational drug and is at least phase 2, suggesting that the drug has shown promise in phase 1 studies and might have a high chance of working well compared to other investigational drugs.

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: Adults with measurable, unresectable locally advanced or metastatic solid tumors that have progressed after standard therapies, enrolled in tumor-specific refractory cohorts (e.g., melanoma post–PD-(L)1, SCCHN post platinum/PD-(L)1, HER2-negative gastric/GEJ, HGS ovarian, cervical, endometrial, urothelial, ESCC, pancreatic, mCRPC, nonsquamous NSCLC without drivers, and HR+/HER2– breast cancer after CDK4/6 and chemo). Single-arm therapy is patritumab deruxtecan (HER3-DXd) 5.6 mg/kg IV q3w, an HER3-targeted antibody–drug conjugate delivering a topoisomerase I inhibitor (DXd).

Investigational drug late phase

The trial is testing an investigational drug and is at least phase 2, suggesting that the drug has shown promise in phase 1 studies and might have a high chance of working well compared to other investigational drugs.

Active drug
