    Includes initial studies to determine the metabolism and pharmacologic actions of drugs in humans, the side effects associated with increasing doses, and to gain early evidence of effectiveness; may include healthy participants and/or patients.
    • Phase I/II
    Principal Investigator


    Primary Objective
    Phase Ib: To determine the maximum tolerated dose (MTD) of IONIS-AR-2.5Rx in combination with enzalutamide.
    Phase II: To estimate the anti-tumor efficacy of IONIS-AR-2.5Rx in combination with enzalutamide as measured by PSA response rate in patients with metastatic castration resistant prostate cancer.

    Secondary Objectives
    1. To estimate secondary measures efficacy of IONIS-AR-2.5Rx in combination with enzalutamide in CRPC subjects including radiographic progression-free survival (rPFS) by PCWG3-modified RECIST 1, 30% PSA reduction proportion, PSA progression-free survival, Duration of Therapy (DOT), Duration of Response (DOR), PFS and OS.
    2. To determine the safety and toxicity of IONIS-AR-5Rx, the Androgen Receptor AntiSense Oligonucleotide (AR ASO) in patients with metastatic castration resistant prostate cancer.
