Current Primary Outcome Measures (submitted: January 26, 2018)

Progression Free Survival [ Time Frame: 2 years ]

Progression Free Survival is defined from the time from randomization to the first occurrence of disease progression as determined by the investigator using RECIST 1.1 or death from any cause, whichever occurs first.

• Original Primary Outcome Measures: Same as current

Current Secondary Outcome Measures (submitted: March 22, 2024)

• Objective Response Rate [ Time Frame: 2 years ]
  Objective Response Rate is determined by Complete Response or Partial Response by RECIST 1.1. Per RECIST 1.1 for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
• Duration of Response [ Time Frame: 3 years ]
  Duration of Response is measured from the time criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented. Per RECIST 1.1 for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions.
• Overall Survival [ Time Frame: 5 years ]
  Overall survival is defined as the time from randomization to death from any cause, or is censored at date last known alive.

• Official Title: A Randomized, Phase II Study Comparing Trastuzumab and Vinorelbine in Combination With Avelumab or Avelumab and Utomilumab (41BB/CD137 Agonist), in Patients With HER2-positive Metastatic Breast Cancer Who Have Progressed on Prior Trastuzumab and Pertuzumab

Brief Summary

This research study is studying a combination of drugs as a possible treatment for breast cancer.

The drugs involved in this study are:

• Group A: Trastuzumab (Herceptin) + Vinorelbine (Navelbine)
• Group B: Trastuzumab + Vinorelbine + Avelumab
• Group C: Trastuzumab + Vinorelbine + Avelumab + Utomilumab (PF-05082566)

Detailed Description

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug combination to learn whether the drug combination works in treating a specific disease. "Investigational" means that drug combination is being studied.

The FDA (the U.S. Food and Drug Administration) has not approved Utomilumab as a treatment for any disease.

The FDA (the U.S. Food and Drug Administration) has approved Avelumab as a treatment for other diseases.

The FDA (the U.S. Food and Drug Administration) has approved trastuzumab as a treatment option for this disease.

The FDA (the U.S. Food and Drug Administration) has approved vinorelbine as a treatment for other diseases and is commonly used as a treatment option for this disease.

The immune system is the body's natural defense against disease. The immune system sends a type of cells called T cells throughout the body to detect and fight infections and diseases-including cancers. One way the immune system controls the activity of T cells is through the PD-1 (programmed cell death protein-1) pathway. However, some cancer cells hide from T-cell attack by taking control of the PD-1 pathway and this stops T cells from attacking cancer cells. Avelumab is a type of drug, known as an antibody which is designed to block the PD-1 pathway and helps the immune system in detecting and fighting cancer cells. An antibody is a protein produced by the body's immune system when it detects harmful substances. Previous studies show that the administration of antibodies which block the PD-1 pathway can lead to tumor destruction.

Utomilumab is an antibody designed to stimulate the body's immune system to fight cancer cells. Previous studies have shown that the administration of this type of antibody may help to prevent tumors from growing.

In the laboratory, adding avelumab and Utomilumab to trastuzumab appears to improve effectiveness. It is not known whether this is true in humans.

In this research study, the investigators are evaluating the activity of 3 different combinations: (a)trastuzumab and vinorelbine combined, (b) trastuzumab, vinorelbine and avelumab combined, and (c) trastuzumab, vinorelbine, avelumab and utomilumab combined in participants with metastatic HER2- positive breast cancer.
