Propranolol and Pembrolizumab for Tumor Re-sensitization and Treatment of Patients With Checkpoint Inhibitor Refractory Metastatic or Unresectable Triple Negative Breast Cancer

Korábbi kezelés

• Patients currently treated with systemic immunosuppressive agents, including steroids, are ineligible until 3 weeks after removal from immunosuppressive treatment
• Patients with primary resistance (i.e., did not respond to initial treatment with chemotherapy plus checkpoint inhibitor) with progressive disease at 12 weeks after starting chemotherapy and pembrolizumab
• Participants with symptomatic known brain metastases < 4 weeks from radiation treatment should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events

Más betegség

• Patients with active autoimmune disease, requiring ongoing immunosuppressive therapy or history of transplantation
• Patients with rapidly progressive disease/ symptomatic disease
• History of malignancy other than breast cancer within 5 years prior to screening, with the exception of those with a negligible risk of metastases or death
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Any additional condition which in the investigator's opinion deems the participant an unsuitable candidate to receive the study drugs

Laborértékek

• Contraindications to the use of beta-blockers, like: uncontrolled depression, unstable angina pectoris, uncontrolled heart failure (grade III or IV), hypotension (systolic blood pressure < 100 mmHg), severe asthma or chronic obstructive pulmonary disease (COPD), uncontrolled type I or type II diabetes mellitus (hemoglobin A1C [HbA1C] > 8.5 or fasting plasma glucose > 160 mg/dl at screening), symptomatic peripheral arterial disease or Raynaud's syndrome, untreated pheochromocytoma, current use of beta-blockers or non-dihydropyridine calcium channel blockers
