Apalutamide in Treating Patients With Prostate Cancer Who Are in Active Surveillance

NCT ID: NCT02721979

Last Updated: 2023-02-09

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE2
• Total Enrollment: 24 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-11-02
• Study Completion Date: 2021-11-30

Brief Summary

This phase II trial studies how well apalutamide works in treating patients with prostate cancer who are in active surveillance. Testosterone can cause the growth of prostate cancer cells. Hormone therapy using androgen receptor antagonist apalutamide may fight prostate cancer by blocking the use of testosterone by the tumor cells.

Detailed Description

OUTLINE:

Patients receive apalutamide orally (PO) once daily (QD) for 90 days in the absence of disease progression or unacceptable toxicity.

After completion of the study treatment, patients are followed up at 180, 365, 545, and 730 days; and at years 3, 4 and 5 by medical record review.

Conditions

Prostate Adenocarcinoma

Study Design

• Allocation Method: NA

Exclusion Criteria

• Prior local therapy to treat prostate cancer (e.g. radical prostatectomy, radiation therapy, brachytherapy)
• Prior use of ARN-509 (apalutamide)
• Have known allergies, hypersensitivity, or intolerance to ARN-509 (apalutamide) or its excipients
• Prior or ongoing systemic therapy for prostate cancer including, but not limited to:

• Immunotherapy (e.g. sipuleucel-T, ipilimumab)
• Chemotherapy (e.g. docetaxel, cabazitaxel)
• Have any condition that, in the opinion of the investigator, would compromise the well-being of the subject or the study or prevent the subject from meeting or performing study requirements
• History of any of the following:

• Seizure or known condition that may pre-dispose to seizure (including but not limited to prior stroke, transient ischemic attack, loss of consciousness within 1 year prior to registration, brain arteriovenous malformation; or intracranial masses such as schwannomas and meningiomas that are causing edema or mass effect)

• Current evidence of any of the following:

• Uncontrolled hypertension

• Any condition that in the opinion of the investigator, would preclude participation in this study
• The use of drugs known to lower the seizure threshold, including: atypical antipsychotics (e.g. clozapine, olanzapine, risperidone, ziprasidone), bupropion, lithium, meperidine, pethidine, phenothiazine antipsychotics (e.g. chlorpromazine, mesoridazine, thioridazine), and tricyclic antidepressants (e.g. amitriptyline, desipramine, doxepin, imipramine, maprotiline, mirtazapine)
