NCT ID: NCT03204812

Last Updated: 2024-10-15

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 31 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-07-14
• Study Completion Date: 2021-04-13

Brief Summary

This phase II trial studies the safety, tolerability and how well durvalumab and tremelimumab work in treating participants with castration-resistant prostate cancer who have not received chemotherapy (chemotherapy naïve) and has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Detailed Description

PRIMARY OBJECTIVE:

I. To evaluate the safety and tolerability of durvalumab plus tremelimumab in patients with metastatic castration-resistant prostate cancer.

SECONDARY OBJECTIVES:

I. To assess the efficacy of durvalumab plus tremelimumab in patients with metastatic castration-resistant prostate cancer. II. To explore immunological changes in peripheral blood and tissue (e.g. peripheral blood cluster of differentiation [CD] 4+ [Inducible COStimulator (ICOS)]+ T cells, CD3 expression in tissue) in response to durvalumab plus tremelimumab in patients with metastatic castration-resistant prostate cancer.

OUTLINE:

Patients receive tremelimumab intravenously (IV) over 60 minutes and durvalumab IV over 60 minutes on day 1. Treatment repeats every 28 days for up to 4 cycles for tremelimumab and up to 13 cycles for durvalumab in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30, 60, and 90 days, and then every 3 months thereafter.

Conditions

Castration-Resistant Prostate Carcinoma; Metastatic Malignant Neoplasm in the Bone; Prostate Adenocarcinoma; Stage IV Prostate Cancer AJCC v8; Stage IVA Prostate Cancer AJCC v8; Stage IVB Prostate Cancer AJCC v8

• Platelet count >= 100 x 10^9/L (>100,000 per mm^3).
• Serum bilirubin =< 1.5 x institutional upper limit of normal (ULN). This will not apply to subjects with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology), who will be allowed only in consultation with their physician.
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]/alanine aminotransferase [ALT] serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal.
• Serum creatinine clearance (CL) > 40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance.
• Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
• Consent to MD Anderson laboratory protocol PA13-0291 and LAB02-152.
• Willing to have peripheral blood mononuclear cells and bone marrow biopsies to be collected prior to receiving the first dose of durvalumab and tremelimumab, after 2-doses and 4-doses of durvalumab and tremelimumab, after 2nd treatment administration and 4th treatment administration.
• Histologically or cytologically confirmed adenocarcinoma of the prostate.
• Evidence of metastatic disease to the bone seen on most recent bone scan, computed tomography (CT) scan and/or magnetic resonance imaging (MRI).
• Asymptomatic or minimally symptomatic patients (do not require narcotics for prostate cancer-related pain).
• Tumor progression while on hormone therapy with castrate levels serum testosterone (=< 1.7 nmol/L or 50 ng/dL) defined by prostate-specific antigen (PSA) and/or radiographic criteria according to the Prostate Cancer Working Group 3 (PCWG3). Castrate levels of testosterone must be maintained by surgical or medical means throughout the conduct of the study.

Exclusion Criteria

• Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site), previous enrollment in the present study.
• Participation in another clinical study with an investigational product during the last 4 weeks.
• Any previous treatment with a PD1 or PD-L1 inhibitor, including durvalumab or an anti-CTLA4, including tremelimumab.
• History of another primary malignancy except for: 1) Malignancy treated with curative intent and with no known active disease >= 5 years before the first dose of study drug and of low potential risk for recurrence. 2) Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease. 3) Adequately treated carcinoma in situ without evidence of disease (e.g., superficial bladder cancer).
• Evidence of visceral metastasis to the liver.
