Study Details

Study Description

Brief Summary

The goal of this research study is to evaluate the safety and feasibility of implanting and retrieving a microdevice that releases microdoses of a specific drug or combination of drugs as a possible tool to evaluate the effectiveness of several cancer drugs against early stage Triple Negative Breast Cancer (TNBC).

The name of the intervention involved in this study is:

Implantable Microdevice (IMD)

Condition or Disease	Intervention/Treatment	Phase
Triple Negative Breast Cancer Breast Cancer Stage II Breast Cancer Stage III Breast Cancer Early Stage Triple-Negative Breast Carcinoma Breast Neoplasms Breast Carcinoma	Combination Product: Implantable Microdevice (IMD)	Phase 1

Detailed Description

This is a single-arm, pilot research study to evaluate the safety and feasibility of using an implantable microdevice to measure local intratumoral response to chemotherapy and other clinically relevant drugs in triple-negative breast cancer (TNBC). A pilot study means that this is the first time investigators are examining this study intervention in TNBC. Participants selected for this study must have a diagnosis of Stage II-III TNBC and are scheduled to undergo neoadjuvant systemic therapy.

This study involves implanting 2 microdevices, each small enough to fit inside the tip of a needle, into a tumor. The microdevices will release microdoses of up to 30 different cancer drugs via passive diffusion. The drugs will only penetrate the local tumor tissues. After approximately 72 hours, the microdevices and small regions of surrounding tissue will be removed and studied.

The U.S. Food and Drug Administration (FDA) has not approved the microdevice as treatment for any disease. For this study, the drugs used are agents approved by the U.S. FDA for the treatment of different types of cancer.

The research study procedures include screening for eligibility, study treatment with evaluations, radiology scans of tumors, blood tests, tumor biopsies, mammograms, and follow-up visits.

It is expected that about 24 people will take part in this research study.

Participants will be followed on this study for up to 3 years.

Outcome Measures

Primary Outcome Measures

Number of Participants with Adverse Events [up to 80 hours]
Defined by assessment of adverse events as defined by CTCAE v5.0.
Number of Participants with Successful Procedure [up to 80 hours]
Defined as the ability to retrieve two implanted microdevices with sufficient tissue, of sufficient quality, for downstream histopathology analysis and interpretation of at least 67% of the microdevice reservoirs in each device.

Secondary Outcome Measures

Local Intratumoral Response (per Apoptosis) [up to 80 hours]
Descriptive statistics will be used to summarize the quantitative measurement of apoptosis (apoptotic index) for drug-treated regions compared to untreated regions of the device.
Local Intratumoral Response (per Proliferation) [up to 80 hours]
Descriptive statistics will be used to summarize the quantitative measurement of proliferation (Ki67) for drug-treated regions compared to untreated regions of the device.
Response to Systemic Neoadjuvant Therapy (RCB Class) [up to 3 years]
Correlation between local intratumoral response with the microdevice and response to systemic neoadjuvant therapy will be evaluated. Clinical response to systemic neoadjuvant therapy will be defined using residual cancer burden (RCB) class.
Response to Systemic Neoadjuvant Therapy (RCB Score) [up to 3 years]

Exclusion Criteria:

Uncontrolled, significant intercurrent or recent illness including, but not limited to, ongoing or active infection, uncontrolled non-malignant systemic disease, uncontrolled seizures, or psychiatric illness/social situation that would limit compliance with study requirements in the opinion of the treating investigator.
Prior hypersensitivity to any of the study drugs implanted with the device.
Pregnant women are excluded from this study because of the possible increased dose of radiation from imaging associated with the device placement (e.g., if placement cannot be performed guided by ultrasound or MRI, if additional imaging and/or procedures are required due to potential complication of the device placement or removal).
