NCT04246671

Brief Summary

A Phase 1 open label trial of intravenous administration of TAEK-VAC-HerBy vaccine in patients with advanced brachyury and/or HER2- expressing cancer. The study will be completed in 2 stages. In Stage 1 patients will be enrolled and treated according to a 3+3 dose escalation scheme. Up to 4 dose levels will be explored to determine the recommended dose of TAEK-VAC-HerBy for Stage 2 of the trial. Stage 2 will enroll either chordoma patients for treatment with TAEK-VAC-HerBy alone, or HER2- positive breast cancer patients for combination treatment of TAEK-VAC-HerBy vaccine and therapeutic HER2 antibodies (trastuzumab). Patients in both stages will receive TAEK-VAC-HerBy intravenously, every three weeks, three administrations in total.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Men and women ≥18 years old.
  • Patients must have histologically documented malignant tumor which is unresectable locally advanced or metastatic.
  • ECOG performance status 0 or 1
  • Patients must have normal organ and bone marrow function as defined in the protocol.
  • Normal left ventricular ejection fraction (LVEF) ≥50%.
  • Troponin I within normal limits.
  • A maximum cumulative dose of prior doxorubicin ≤360 mg/m2 or epirubicin ≤720 mg/m2
  • Any approved cancer therapy (except HER2 antibodies) must be completed at least 3 weeks or 5 half-lives for small molecule inhibitors, whichever is shorter, prior to the first planned dose of TVH vaccine.
  • HER-2 positive cancer: Patients are required to be on active treatment with HER2 antibodies (trastuzumab) prior to and during study treatment.
  • Chordoma patients with progressive extracranial chordoma (base of skull is permitted) not amenable for surgical resection with curative intent, nor for radiation therapy will be enrolled.
  • Patients must have recovered (Grade 1 or baseline) from any clinically significant toxicity associated with prior therapy.
  • Patients must have measurable disease by computed tomography (CT) or magnetic resonance imaging (MRI) per RECIST 1.1.

You may not qualify if:
