Measure
Treatment (Pembrolizumab, HER2Bi-armed Activated T Cells)
Patients receive pembrolizumab IV over 30 minutes every 3 weeks. Treatment repeats every 3 weeks for up to 6 months in the absence of disease progression or unacceptable toxicity. Beginning at least 1 week after pembrolizumab, patients receive HER2Bi-armed activated T cells IV over 5-15 minutes 2 times a week for 4 weeks in the absence of disease progression or unacceptable toxicity.
