Could everyday aspirin and statins fight advanced prostate cancer?
NCT ID NCT03819101
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 3 trial is testing whether taking aspirin and atorvastatin (a common cholesterol-lowering drug) can help men with castrate-resistant prostate cancer live longer. The study plans to enroll 1210 participants who are starting their first treatment for this advanced stage. Researchers will compare survival rates between those taking the drugs and those not, to see if this simple combination offers a benefit.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- acetylsalicylic acid (aspirin) and atorvastatin (a statin)
- What this could lead to
- If it works, this could offer a simple, low-cost way to extend survival for men with advanced prostate cancer that no longer responds to hormone therapy.
- What could go wrong
- This is a large phase 3 trial, but the drugs are already widely used for other conditions; their benefit for prostate cancer is unproven. There is a risk of side effects like bleeding or muscle pain.

Inclusion Criteria: * Histologically confirmed adenocarcinoma of the prostate and no curative local therapy considered possible * Age ≥ 18 years, life expectancy of at least 6 months * CRPC defined as tumor progression (PSA increase on at least 2 separate values separated by at least 1 week or progression on imaging) while on Androgen Deprivation Therapy (orchiectomy, LHRH agonist or -antagonist) with documented serum testosterone levels ≤ 1.7 nmol/L (≤ 0.50 ng/mL). Ongoing concurrent use of LHRH agonist or antagonist is required if the patient has not been surgically castrated * Presence (M1) or absence (M0) of metastases on imaging * Performance status 0, 1 or 2 * No previous use of life- prolonging treatments for CRPC (including abiraterone, enzalutamide, radium-223, docetaxel, cabazitaxel, and sipuleucel-T). The use of these agents together with Androgen Deprivation Therapy (ADT) for castrate-sensitive disease is allowed. * Adequate renal function within 30 days prior to registration: calculated creatinine clearance ≥ 50 mL/min, according to the formula of Cockcroft-Gault and adequate liver function with levels of AST and ALT ≤ 3xULN and no signs for cholestasis. * Participation in other clinical trials is allowed except for trials with the same primary endpoint, i.e. OS * Patient authorized to participate to a clinical trial by specific country regulation (eg patient affiliated to a social security system or beneficiary of the same) * Information delivered to patient and informed consent form signed by the patient. Exclusion Criteria: * Previous localised malignancy within 2 years with the exception of localized non-melanoma skin cancer and Ta or Tis bladder cancer (patients with asymptomatic Chronic Lymphocytic Leukemia can be included) * Previous metastatic malignancy within 5 years * Patient currently taking daily acetylsalicylic acid or a daily statin within the last 6 months * Patients with active liver disease (hepatitis B or C, cirrhosis) or unexplained persistent elevations of serum transaminases exceeding 3 times the upper limit of normal or cholestasis * Patients with excessive alcohol intake or history of a relevant liver disease * Known hypersensitivity or intolerance to acetylsalicylic acid or atorvastatin or hypersensitivity to any of its components * Contra-indication to acetylsalicylic acid or atorvastatin according to label, including known high-risk for haemorrhage, * History of or active myopathy or significantly elevated (\> 5 times ULN) CK levels * History of recent stroke or transient ischemic attack (TIA). * Any concomitant drugs contraindicated for use with the trial drugs according to the product information (e.g. Fusidic acid, potent inhibitors of CYP3A4 or transport proteins: ciclosporin, telithromycin, clarithromycin, delavirdine, stiripentol, ketoconazole, voriconazole, itraconazole, posaconazole and HIV protease inhibitors including ritonavir, lopinavir, atazanavir, indinavir, darunavir, tipranavir, telaprevir, saquinavir, darunavir, fosamprenavir, boceprevir, gemfibrozil, fenofibrate, etc) * Any serious underlying medical condition (by the investigator's judgement) which could impair the ability of the patient to participate in the trial * Patients with hereditary galactose intolerance, Lapp-lactase deficiency or Glucose-Galactose-malabsorption * Compliance with trial medical follow-up impossible due to geographic, social or psychological reasons * Psychiatric disorder precluding understanding of information about trial related topics, providing informed consent, or interfering with compliance for oral drug intake
