Andrew John Armstrong

Professor of Medicine
Medicine, Medical Oncology
Duke Box 103861, Durham, NC 27710
GSRB1 Room 3006, 905 La Salle St, Durham, NC 27710

Overview


I am a clinical and translational investigator focused on precision therapies and biomarkers in advanced prostate and other GU cancers.  I oversee a large research team of clinical and lab based investigators focused on improving patient outcomes, preventing metastatic disease, and understanding the biology of aggressive prostate cancer.  Some key themes:
1. Predictors of sensitivity and clinical efficacy of therapies in advanced prostate cancer
2. Novel designs of clinical trials and pharmacodynamic/translational studies in prostate, kidney, bladder cancer
3. Pre-operative models for drug development of novel agents in human testing in prostate cancer
4. Novel therapies and drug development for prostate, renal, bladder, and testicular cancer
5. Design of rational combination therapies in men with metastatic hormone-refractory prostate cancer
6. Developing prognostic and predictive models for progression and survival in metastatic prostate cancer
7. Examining surrogate markers of mortality in metastatic prostate cancer
8. Biologic basis for prostate cancer lineage plasticity, immune evasion, hormone therapy, and metastasis

Cytoplasmic versus nuclear localization of androgen receptor splice variant 7 as a predictor of benefit from androgen receptor pathway inhibitors in metastatic castration-resistant prostate cancer (PROPHECY trial).

Journal Article Prostate Cancer Prostatic Dis · April 2, 2026 BACKGROUND: Androgen receptor splice variant-7 (AR-V7), a constitutively active truncated protein, is linked to hormone therapy resistance. Nuclear AR-V7 in CTCs correlates with poor response and shorter progression-free survival (PFS) and overall survival ... Full text Link to item Cite
