FLAMINGO-01

New Drug

GM-CSF (immune stimulation) +GP2 (a small section of the HER2/neu protein) versus placebo.

This is the most advanced clinical trial for a vaccine-type therapy for breast cancer.

  • HER2-positive
  • Residual cancer or high risk after chemo+surgery
  • HLA-A*02 Positive (immune type)
  • Active autoimmune disease
  • Prior HER2-targeted vaccine therapy

ShortStop-HER2

New Approach

Whether HER2-targeted treatment after surgery (eg. trastuzumab) can be reduced from 12 months to 6.

This is a de-escalation trial exploring whether treatment duration can be safely reduced to minimize adverse impacts.

  • HER2-positive
  • Early stage
  • Complete response to neoadjuvant treatment (prior to surgery)
  • Within 14 weeks of surgery
  • Did not receive trastuzumab before surgery
  • Cancer remaining after surgery
  • Heart failure
