About this trial

This phase I trial investigates the side effects and best dose of using a modified measles virus, MV-s-NAP, in treating patients with invasive breast cancer that has spread to other places in the body (metastatic). Both the unmodified vaccination measles virus (MV-Edm) and this modified virus (MV-s-NAP) have been shown to multiply in and destroy breast cancer cells in the test tube and in research mice. MV-s-NAP has been altered by having an extra gene (piece of deoxyribonucleic acid \[DNA\]) so that virus can make a protein called helicobacter pylori neutrophil activating protein (NAP) which is normally expressed in inflammatory reactions. Monitoring blood, urine, tissue, and throat swab samples, and using imaging tests may help to determine whether MV-s-NAP has any impact on the amount of disease present in metastatic breast cancer patients.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age >= 18 years

COHORT 1 ONLY: Pathologically confirmed invasive breast adenocarcinoma with documented estrogen receptor (ER)/progesterone receptor (PR) /HER2 status and radiographic evidence of distant metastatic disease

COHORTS 2 & 3 ONLY: Pathologically confirmed invasive breast adenocarcinoma with documented ER/PR/HER2 status and radiographic evidence of distant metastatic or recurrent disease

COHORT 1 ONLY: Radiographic evidence of distant metastatic disease (using 7th edition American Joint Committee on Cancer [AJCC] criteria) with two discrete sites of measurable disease

Disqualifiers

Known standard therapy for the patient's disease that is potentially curative or definitely capable of extending life expectancy

Clinical or radiographic suspicion of impending visceral crisis due to invasion or compression by tumor

Active infection =< 5 days prior to registration

History of other malignancy =< 5 years except for non-melanoma skin cancer or carcinoma in situ of the cervix

Trial outcomes

Primary outcomes

1

Maximum tolerated dose

This is defined as the highest dose level among those under consideration where at most one of 6 patients develops a dose limiting toxicity, and two or more of the 3-6 patients treated at the next higher dose level develop a dose limiting toxicity.

Time frame
During the first cycle of treatment (each cycle = 21 days)
2

Best tumor response

The best tumor response in the injected and non-injected lesion will be determined using Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Results will be tabulated for the entire cohort and by breast cancer subtype in terms of whether there was response in none of the lesions, only the injected lesion, or both lesions.

Time frame
Up to 2 years
3

Incidence of adverse events

The maximum grade of each type of toxicity will be recorded for each patient. For each toxicity reported by dose level, the percentage of patients developing any degree of that toxicity, as well as the percentage of patients developing a severe (grade 3 or higher) toxicity, will be determined.

Time frame
Up to 2 years
4

Measles virus viremia

Defined as detection of any titer of virus by quantitative real time-polymerase chain reaction performed with patient peripheral blood mononuclear cells. Viremia will be examined in terms of the day and dose level it was detected, as well as the time to recovery.

Time frame
Up to 2 years

Secondary outcomes

1

Tumor response

The best tumor response in the injected and non-injected lesion will be determined using Response Evaluation Criteria in Solid Tumors (RECIST). Results will be tabulated by dose level and whether there was a response in none of the lesions, only the injected lesion, or both lesions.

Time frame
Up to 2 years
2

Progression-free survival (PFS)

PFS is defined as the time from study entry to the documentation of disease progression.

Time frame
Up to 2 years
3

Overall survival (OS)

OS is defined as the time from study entry to death due to any cause.

Time frame
Up to 2 years
