Study summary

Patients with cancer are at high risk for life-threatening venous thromboembolism (VTE) yet rarely receive anticoagulant prophylaxis due to bleeding risks. Thus, effective prophylaxis in oncology requires a method to reduce VTE without increasing hemorrhage.

The primary aim of the Statin Therapy to Prevent Cancer Associated Venous Thromboembolism (STAT-CAT) trial is to test whether rosuvastatin 20 mg daily for 12 months compared to placebo can safely prevent VTE in patients with newly diagnosed or recently relapsed cancer who are at increased thrombotic risk, are not planned to be anticoagulated, and who do not otherwise take statin therapy.

Read the detailed description

This trial is a randomized, double-blind, placebo-controlled trial of rosuvastatin 20 mg po daily in the prevention of venous thromboembolism (VTE) and other cardiovascular events among individuals recently diagnosed with cancer who are not scheduled to receive prophylactic anticoagulation and are at risk for VTE as defined by a Khorana Score (KS) 2 to 4 or a modified Khorana Score (mKS) 2 to 5.

  • > 6 months

Exclusion criteria

Exclusion Criteria:

  • current use of statin therapy or known statin intolerance.
  • current use of systemic anticoagulation.
  • very low VTE risk defined by a Khorana Score (KS) of 0-1 and a modified Khorana Score (mKS) of 0-1.
  • extremely high VTE risk defined by a Khorana Score (KS) > 5 or modified Khorana Score (mKS) > 6 where guideline recommendations for systemic anticoagulation should be considered.
  • Basal cell or squamous cell carcinoma in situ cancers of the skin as the sole qualifying cancer type
  • ineligible cancer types where level of acuity is likely to preclude trial participation (including acute leukemia, myelodysplastic syndromes, primary brain tumors, primary CNS lymphoma, or plans to undergo hematopoietic stem cell transplantation or CAR-T cell therapy). (g) Known , AST, or creatine kinase (CK) levels > 3 x ; \< 30 ml/min/1.73m2, or Class B or C liver disease
  • Known or disease, or intent to use certain oncologic agents (daralutemide, regorafenib, and cabozantinib) or some antivirals used to treat hepatitis C or HIV disease (combinations of sofosbuvir, velpatasvir, and voxilaprevir) which can significantly increase rosuvastatin exposure and potentially lead to drug-drug interactions (DDIs).
  • Conditions that, in the opinion of the investigator, would compromise the well-being of the subject or conduct of the study, including as examples less than 6 months or an Performance Status > 3.
Terms in these criteria, in plain language(12)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What researchers measure

Primary outcomes

  1. Assess whether Rosuvastatin versus placebo over a period of one year reduces the risk of incident (first event) VTE among patients with cancer

    The primary endpoint of the trial is the time from taking the first dose of study medication after randomization (modified intention to treat, mITT) to the first confirmed occurrence of the primary VTE endpoint. The primary analysis will use a likelihood ratio test based on a proportional hazards model stratified by eligibility criteria (eligible due to KS criteria alone or eligible due to mKS criteria), and enrollng center to test the null hypothesis of no association between assignment to active statin treatment and the rate of the primary endpoint. All analyses will classify patients according to their randomized treatment assignment, i.e. according to the intention to treat principle, and will base evaluation of statistical significance on a two-sided test with level 0.05. The estimated relative hazard in the statin compared to the placebo group with accompanying 95% confidence interval will quantify the treatment effect45. If this relative hazard is less than 1, then 100\*(1-esti

    Time frame: 12 months

Secondary outcomes

  1. Assess whether Rosuvastatin versus placebo over a period of one year reduces the cumulative incidence of a composite of venous and arterial thrombosis events among patients with cancer

    Time frame: 12 months

Other outcomes

  1. Safety Endpoint: Identify transaminitis > 5 x ULN on two consecutive tests at least one week apart

    Time frame: 12 months

  2. Safety Endpoint: Identify CK > 5 x ULN on two consecutive tests at least one week apart

    Time frame: 12 months

  3. Safety Endpoint: Identify clinical myositis, rhabdomyolysis, major bleeding and clinically relevant non-major bleeding

    Time frame: 12 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 16, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
