In this research study, is assessing the feasibility of using an MR-guided implantable microdevice to measure tumor response to chemotherapy and other clinically relevant drugs in participants that have prostate cancer and are scheduled for a radical prostatectomy.
The name of the study intervention involved in this study is:
- Implantation of a MR-guided microdevice
This research study is assessing the feasibility and safety of implanting and retrieving a 'microdevice' that releases up to 20 drugs directly within the prostate cancer lesion as a possible tool to evaluate the effectiveness of several approved cancer drugs against prostate cancer.
Participants will be identified with confirmed prostate cancer whose treatment plan includes surgery as a component of standard-of-care treatment.
The name of the study intervention involved in this study is:
Implantation of a MR-guided microdevice .
It is expected that about 35 people will take part in this research study; 5 in the Ex Vivo Cohort and 30 in Surgery Cohort.
This research study is a Pilot Study, which is the first-time investigators are examining this study intervention. The FDA (the U.S. Food and Drug Administration) has not approved the implantation of the microdevice for this specific disease, but usage of this has been approved for other uses.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Surgery Cohort | Experimental | Participant eligibility for intervention and selection of lesion for device placement - Surgery Cohort will undergo percutaneous placement of several microdevices in a selected tumor(s) prior to surgery. The microdevice in the surgery cohort will dwell in the tumor tissue for approximately 48 hours to allow time for tissue effects of the drugs in the microdevice reservoirs. Placement of at least 1, and up to 6, microdevices depending on the number of lesions, size and accessibility
|
|
| Ex-Vivo Cohort | Experimental | Each participant will undergo a screening process to determine their eligibility for microdevice placement, consisting of the following items:
|
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Microdevice | Combination Product | Surgery Cohort: Placement of 1-6 microdevices: Drugs chosen have all been FDA approved for the treatment of cancer (so therefore safe) and there are phase 2 or 3 data that the drug has efficacy in prostate cancer. Agents of interest included Abiraterone, Enzalutamide, Pembrolizumab, Ipilimumab, Carboplatin, Docetaxel, and Olaparib as well as combinations Ex vivo Cohort: Placement of multiple microdevices with miniature drug reservoirs but no drug is loaded into the removed prostate |
| Measure | Description | Time Frame |
|---|---|---|
| Number of participants with adverse events as defined in the CTCAE v4.0 | Safety of microdevice placement and removal based on assessment of adverse events | From the time of arrival to interventional radiology for microdevice placement up to 6 weeks. |
| Number of Participants with successful surgical Placement and retrieval of Microdevice |
| 48 Hours |
| Measure | Description | Time Frame |
|---|---|---|
| Local intratumor response | measure local intratumor response to clinically relevant cytotoxic agents and small molecule drugs in prostate cancers using quantitative histopathologic assessment of tumor tissue. All inferences of secondary endpoints will use two-sided alpha = 0.05 and report 95% confidence intervals with any point estimates. Descriptive statistics will be used to summarize the quantitative measurements of apoptosis, proliferation, DNA repair, etc. for drug-treated regions compared to vehicle-treated regions. At least two separate regions will contain vehicle to account for tumor heterogeneity. |

Eligibility Criteria: Ex Vivo Cohort
Inclusion Criteria
Exclusion Criteria -- Unwillingness to sign informed consent.
Eligibility Criteria: Surgical Cohort
Inclusion Criteria
Participants must have the ability to understand and the willingness to sign a written informed consent document.
Patients must have the ability to understand and the willingness to sign a written informed consent document at the study site when both the investigator and participant are at the same location, or remotely (e.g., at the participant's home or another convenient venue) where the participant reviews the consent document with the Licensed Physician Investigator over secure Zoom. The electronic consent system, Adobe, ensures the participant electronically signing the informed consent is the subject who will be participating in the research study.
Participants must present with prostate cancer falling into an intermediate or high risk category to include features: Gleason score 3+4 or higher, greater than 3 biopsy cores positive and ≥50% of 1 core positive for carcinoma, and an MRI-visible lesion concerning for PCa in the region of the positive biopsy.
Participants must be 22 years of age or older.
Participants must be evaluated by a urologic oncologist who will determine the clinically appropriate treatment strategy based on clinical history and extent of disease.
Participants must be deemed medically stable to undergo both percutaneous procedures and standard-of-care surgical procedures by their treating surgeon.
Participants must have undergone multi-parametric prostate MRI that both assesses the extent of disease and allows the research team to assess for study eligibility. This will have been done as part of the standard-of-care. Abnormal imaging will be correlated with the biopsy findings to maximize the likelihood of the device being put in the lesion. If the images are not adequate, the MRI scan will be repeated at BWH/DFCI, again as part of standard-of-care management.
The participant's case must be reviewed by representatives of urologic oncology and interventional radiology to assess the following factors:
Participants must be willing to undergo research-related genetic sequencing (somatic and germline) and data management, including the deposition of de-identified genetic sequencing data in NIH central data repositories.
For men: agreement to refrain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm during the treatment period and for 28 days after the last dose of ipatasertib.
