Study Description
Brief Summary
To learn if the proposed dose of 177Lu rhPSMA-10.1 is safe. Phase 2 will open if the Phase 1 dose is found to be safe.
To learn about the safety and effects of 177Lu rhPSMA-10.1 alone and with androgen deprivation therapy (ADT) on patients with high-risk, localized prostate cancer before they have surgery to remove the disease.

Phase 1/Phase 2 |
Detailed Description
Primary Objectives:
The primary objective of the study is to assess safety and toxicity of 177Lu rhPSMA-10.1 Injection and to assess the impact of 177Lu rhPSMA-10.1 Injection with and without ADT on radiation dose delivered to the tumor in high risk localized and locoregional prostate cancer prior to primary radical prostatectomy with lymph node dissection.
Secondary Objectives:
-
To assess the impact on pathologic outcomes at radical prostatectomy after 2 cycles of 177Lu rhPSMA-10.1 Injection with and without ADT Exploratory Objectives
-
To evaluate the IHC expression of PSMA on pre-treatment prostate biopsy specimen compared to post ADT and 177Lu rhPSMA-10.1 Injectiontreatment surgical pathology
-
To assess the impact on PSMA PET signal after treatment with 177Lu rhPSMA-10.1 Injection with and without ADT
-
To evaluate efficacy of neoadjuvant 177Lu rhPSMA-10.1 Injection with or without ADT in men with high-risk and localized prostate cancer planned to undergo radical prostatectomy
-
To evaluate exploratory predictive biomarkers for 177Lu rhPSMA-10.1 Injection with or without ADT including circulating tumor cells and extracellular vesicles

PSA >20 ng/mL
Very high:
-
Has at least one of the following:
-
cT3b-cT4
-
Primary Gleason pattern 5
-
2 or 3 high-risk features
-
4 cores with Grade Group 4 or 5
-
Prostate biopsy within 90 days prior to randomization is allowed for entry requirements. Prostate biopsy must be reviewed at MD Anderson Cancer Center. Patients with small cell, neuroendocrine, or transitional cell carcinomas are not eligible
-
ECOG performance status (PS) grade 1
-
No evidence of metastatic disease or clinically positive lymph nodes as documented by technetium99m (99mTc) bone scan and by computed tomography (CT) or magnetic resonance imaging (MRI) scans. Imaging may be obtained up to 60 days prior to randomization
-
Minimum prostate tumor volume of 1.5 cm3 or greater as measured on prostate MRI within 60 days prior to randomization
-
Distant metastatic disease or clinically positive lymph nodes not identified by conventional imaging including by technetium-99m (99mTc) bone scan and by computed tomography (CT) or magnetic resonance imaging (MRI) scans but identified PSMA PET is allowed based on provider discretion
-
PSMA expression within the primary tumor with a minimum SUVmax of the primary tumor of at least 8
-
Localized or locally advanced disease deemed by the surgeon to be resectable. Patients must be appropriate candidates for and plan to undergo radical prostatectomy and pelvic lymph node dissection
-
No prior treatment for prostate cancer including prior surgery (excluding transurethral resection of the prostate [TURP]), cryoablation, pelvic lymph node dissection, radiation therapy, hormonal therapy or chemotherapy
-

-
Hemoglobin ≥11 g/dL
-
Absolute neutrophil count ≥1.5 x 109/L
-
Platelet count ≥150 x 109/L
-
Adequate renal function defined as creatinine <1.5 x ULN or estimated glomerular filtration rate >60 mL/min/1.73 m2 using BSA with CKD-EPI
-
Adequate hepatic function documented by:
-
Total bilirubin ≤1.5 x ULN
-
AST ≤2.5 x ULN
-
ALT ≤2.5 x ULN
-
Alkaline Phosphatase (ALP) ≤2.5 x ULN

To avoid risk of drug exposure through the ejaculate (even men with vasectomies), subjects must use a condom during sexual activity while on study drug and for 6 months following the last dose of study drug. If the subject is engaged in sexual activity with a woman of childbearing potential, a condom is required along with another effective contraceptive method consistent with local regulations regarding the use of birth control methods for subjects participating in clinical studies and their partners. Donation of sperm is not allowed while on study drug and for 3 months following the last dose of study drug.
Exclusion Criteria:

-
Currently enrolled in another interventional study
-

Patients with HIV must agree to adhere to anti-retroviral therapy for the entirety of their participation in the protocol unless dictated by treatment toxicities.
-
Patients on Tenofovir will be excluded as there is a known risk of proximal renal tubule dysfunction leading to renal toxicity. Given that PSMA is expressed on the proximal tubule there is a theoretical risk of overlapping toxicity.
